Which Heat Pump Features Matter Most for Smyrna, DE Homes

Heat pump installation in Smyrna, DE requires variable-speed technology and proper sizing to handle Delaware's humid climate while delivering year-round comfort and efficiency.

Does heat pump technology work efficiently in Delaware winters?

Modern heat pumps maintain full heating capacity down to temperatures well below Smyrna's typical winter lows of 20-30 degrees.

Earlier generation heat pumps struggled when outdoor temperatures dropped below freezing. Efficiency plummeted and systems switched to expensive backup electric resistance heating. Technology has advanced dramatically in recent years through improved refrigerants, enhanced compressor designs, and variable-speed operation.

Today's cold-climate heat pumps extract usable heat from outdoor air even when temperatures reach zero or below. Delaware's moderate winter climate makes them ideal candidates for heat pump heating. Smyrna rarely experiences the prolonged deep freezes that challenge these systems in northern states.

Variable-speed compressors adjust output to match changing conditions rather than cycling on and off. This continuous modulation maintains consistent indoor temperatures while using less electricity than single-speed models. During mild winter days, the system runs at lower speeds for quiet, efficient operation. When temperatures drop, output increases smoothly without performance gaps.

What efficiency ratings actually indicate for your energy bills?

SEER2 measures cooling efficiency while HSPF2 indicates heating performance, with higher numbers translating directly to lower operating costs throughout the year.

The Department of Energy recently updated efficiency standards to better reflect real-world conditions. SEER2 replaced SEER for cooling measurements, while HSPF2 superseded HSPF for heating metrics. These new standards account for variable outdoor temperatures and humidity levels more accurately.

For Smyrna homes, look for minimum SEER2 ratings of 15-16 and HSPF2 ratings above 8. Premium models reach SEER2 values of 20+ and HSPF2 numbers around 10-12. The efficiency difference matters more than marketing suggests. Moving from a 14-SEER2 unit to an 18-SEER2 system reduces cooling costs by roughly 28 percent.

Heating efficiency gains prove equally significant. A heat pump with 9 HSPF2 uses about 40 percent less electricity for heating than older 6 HSPF2 models. Over Delaware's heating season from November through March, these savings compound into hundreds of dollars annually.

Energy efficiency also affects comfort beyond just costs. More efficient systems remove humidity better during summer operation. They distribute heat more evenly in winter because variable-speed fans match airflow to actual needs rather than blasting at maximum constantly.

How does Delaware's housing stock influence heat pump selection?

Smyrna's mix of older homes with outdated insulation and newer construction requires different heat pump approaches for optimal performance and comfort.

Many Smyrna residences date back decades, built before modern insulation standards existed. These homes leak heat in winter and gain it rapidly during summer. Older windows, minimal attic insulation, and gaps around doors create thermal challenges that affect heat pump sizing.

Contractors must perform detailed load calculations accounting for actual building characteristics. Simply matching tonnage to square footage fails in older homes. An undersized system runs constantly without keeping pace with heat loss or gain. Oversized equipment cycles on and off rapidly, failing to dehumidify properly and wasting energy.

Ductwork condition matters tremendously for heat pump efficiency. Many older Smyrna homes have duct systems designed for oil or gas furnaces that produce hotter air than heat pumps. The ducts may leak, lack insulation in unconditioned spaces, or have design flaws that reduce airflow. Professional assessment identifies these issues before installation rather than discovering problems after your new system performs poorly.

Newer construction typically features better insulation and tighter building envelopes. These homes benefit from properly sized heat pumps that operate at designed efficiency levels. The reduced heating and cooling loads mean smaller, less expensive systems handle the space comfortably. Pairing new equipment with quality construction maximizes both comfort and energy savings.

Can single-zone systems handle whole-home comfort?

Multi-zone heat pump installations solve temperature variations between floors and rooms that plague single-zone systems in larger or multi-story homes.

Traditional central heat pumps use a single indoor unit connected to ductwork throughout your home. Upstairs bedrooms may roast while the main floor stays comfortable, or vice versa. The thermostat location dictates operation regardless of conditions elsewhere.

Multi-zone systems employ individual indoor units in different areas, each with independent temperature control. Upstairs bedrooms can be cooler for sleeping while living spaces maintain different settings. Everyone gets comfortable without compromising or arguing over thermostat battles.

Ductless mini-split configurations work particularly well in homes lacking existing ductwork or in additions where extending ducts proves impractical. Each indoor head mounts on a wall or ceiling, connected to the outdoor compressor through small refrigerant lines. You gain precise zone control while avoiding major construction disruption. Consider combining heat pump services in Smyrna with strategic zone planning for maximum comfort and efficiency.

Energy savings from zoning prove substantial. Why heat or cool empty rooms to the same level as occupied spaces? Zoned systems focus conditioned air where needed, when needed. Guest rooms stay at minimal settings until visitors arrive. Home offices maintain comfortable temperatures during work hours then scale back overnight.

What installation factors determine long-term performance?

Proper refrigerant charging, correct airflow settings, and outdoor unit placement affect efficiency and reliability more than equipment brand or model selection.

Heat pumps operate on precise refrigerant charges. Too little refrigerant reduces capacity and efficiency while potentially damaging the compressor. Excess refrigerant causes similarly poor performance plus additional operating problems. Installing contractors must measure charge carefully using digital manifolds and temperature measurements, not guesswork.

Airflow through your system must match manufacturer specifications within narrow tolerances. Too little airflow across indoor coils causes freezing and capacity loss. Excessive airflow reduces dehumidification and wastes fan energy. Proper duct design, correctly sized return air pathways, and appropriate fan settings ensure optimal operation.

Outdoor unit location impacts both performance and longevity. The compressor needs adequate clearance for airflow and service access. Placement too close to walls, fences, or landscaping restricts air movement and reduces efficiency. Shading from afternoon sun helps, but units require unobstructed space above and around them.

Consider noise impact when positioning outdoor equipment. Even quiet heat pumps produce some sound during operation. Placing the unit near bedroom windows or outdoor living areas creates annoyance issues. Professional installers balance efficiency requirements, service accessibility, and noise considerations.

Condensate management prevents water damage and system shutdowns. Heat pumps in cooling mode generate significant moisture that must drain properly. Delaware's humid summers mean heavy condensate production. Drain lines need correct slope, clean paths to disposal points, and protection against blockage. Winter heating operation can also produce condensate requiring drainage.

Quality installation includes electrical work meeting local codes and manufacturer requirements. Heat pumps draw substantial current, demanding proper wire sizing, disconnect switches, and overcurrent protection. Improper electrical work creates fire hazards and equipment damage while voiding warranties.

Heat pumps deliver exceptional efficiency and comfort for Smyrna homes when properly selected and installed. The technology handles Delaware's climate effectively while reducing energy costs and environmental impact compared to traditional heating and cooling methods.

When Air Conditioning Breakdowns Strike Most Often in Dover, DE

Fri, 20 Feb 2026 14:53:59 GMT

When Air Conditioning Breakdowns Strike Most Often in Dover, DE

Air conditioning repair needs in Dover, DE peak during June through August when extreme heat strains cooling systems beyond their normal operating limits.

Which warning signs appear before complete AC failure?

Weak airflow and warm air coming from vents signal urgent repair needs before your system stops working entirely.

Your air conditioner works through precise mechanical and refrigerant processes. When components start failing, the system tries to compensate before eventually giving up. Most breakdowns don't happen suddenly—they announce themselves through subtle changes in performance weeks before complete failure.

Pay attention to temperature inconsistencies between rooms. One bedroom feeling like summer while another stays comfortable indicates ductwork issues or failing zone controls. Unusual sounds like grinding, squealing, or banging mean mechanical components are wearing out. Metal-on-metal grinding suggests motor bearing failure, while squealing often points to belt problems.

Moisture where it doesn't belong tells important stories. Water pooling around your indoor unit means either condensate drain blockage or frozen evaporator coils. Refrigerant leaks leave oily residue and cause ice formation on copper lines. Both issues require immediate attention to prevent compressor damage.

Do Dover summers create unique AC challenges?

High humidity levels combined with coastal heat make Delaware air conditioners work significantly harder than systems in drier climates.

Dover's location in the Mid-Atlantic creates demanding conditions for cooling equipment. Summer temperatures regularly push into the 90s while humidity stays elevated due to proximity to Delaware Bay and the Atlantic Ocean. This combination forces your AC to run longer cycles removing both heat and moisture from indoor air.

The extra work accelerates wear on critical components. Compressors labor against back pressure from humid outdoor air. Evaporator coils handle heavier moisture loads, increasing freeze-up risks if airflow drops even slightly. Capacitors that start compressor motors fail faster under sustained heavy usage.

Many Dover homes rely on AC units originally sized for heating-dominated climates. These undersized systems run nearly nonstop during heat waves, never quite catching up with cooling demand. Constant operation prevents proper cycling, eliminating rest periods motors need to avoid overheating. You get reduced comfort and accelerated equipment failure.

What causes most emergency repair calls during summer?

Refrigerant leaks, failed capacitors, and clogged condensate drains account for roughly 70 percent of emergency service requests between June and August.

Refrigerant doesn't get consumed—your system operates on a sealed loop. When levels drop, leaks exist somewhere in the refrigerant circuit. Small leaks worsen over time as vibration and temperature cycling stress compromised joints. By summer, years-old pinhole leaks become large enough to drop refrigerant below functional levels.

Capacitors store electrical energy to start compressor and fan motors. Delaware's humid heat creates ideal conditions for capacitor failure. The components contain electrolytic fluid that evaporates faster in high temperatures. Once fluid levels drop, the capacitor can't store enough charge to start motors reliably. Your system tries to run, hums loudly, then shuts down on safety limits.

Condensate drains remove humidity your AC pulls from indoor air. A central air system can produce 20 gallons of water daily during humid Delaware summers. When algae or debris blocks the drain line, water backs up into overflow pans. Modern systems shut down automatically to prevent water damage, leaving you without cooling until the blockage clears.

Dirty air filters deserve special mention. A clogged filter restricts airflow across evaporator coils, causing ice formation. The frozen coils stop absorbing heat, and ice buildup eventually blocks airflow completely. Your system runs constantly while indoor temperatures climb. This simple maintenance issue triggers expensive service calls when homeowners don't realize a $20 filter caused the problem.

How do Dover's building codes affect AC repairs?

Delaware requires permits for refrigerant work and electrical modifications, adding planning time and ensuring repairs meet safety standards for humid coastal conditions.

State regulations protect homeowners by requiring licensed technicians for refrigerant handling. This prevents improper repairs that worsen environmental damage and equipment performance. When your AC needs refrigerant work, technicians must identify and fix leaks before adding refrigerant. Simply topping off a leaking system wastes money and violates EPA regulations.

Electrical permits apply to compressor replacements, condenser installations, and any work involving your home's electrical panel. The permitting process verifies installations can handle Dover's humidity without creating shock hazards or fire risks. Outdoor disconnect boxes need weatherproof ratings suitable for coastal moisture exposure. Indoor components require proper clearances and protection from water damage.

Licensed contractors understand these requirements and handle permit applications as part of normal service. Unlicensed workers skip permitting to save time and money, leaving you liable for code violations and insurance claim denials if problems arise. The upfront permit cost proves minor compared to risks of substandard electrical work in a humid climate.

When should you replace rather than repair?

Systems older than 12 years facing major component failure often cost less to replace than repair, especially with modern efficiency gains.

Air conditioners manufactured before 2010 use outdated refrigerant that's being phased out environmentally. R-22 refrigerant prices have tripled in recent years as production ends. A leak repair and recharge on an old system can cost nearly as much as new equipment using modern refrigerant.

Calculate the 50 percent rule for repair decisions. Multiply your system's age by repair cost estimate. If the result exceeds half the replacement cost, new equipment makes better financial sense. A 14-year-old unit needing a $1,400 compressor replacement crosses this threshold easily since new systems start around $4,000 installed.

Energy efficiency matters more than many homeowners realize. Moving from a 10-SEER older unit to an 16-SEER modern system can cut cooling costs by 37 percent. Over 10 years of Delaware summers, efficiency improvements often exceed the price difference between repair and replacement. You gain reliability, lower utility bills, and better humidity control.

Consider pairing new equipment with indoor air quality services in Dover to maximize comfort and efficiency. Modern systems integrate with advanced filtration and ventilation options that older units can't support. The combined upgrade improves both temperature control and air freshness throughout your home.

System age affects more than reliability. Manufacturers discontinue parts support for models over 10 years old. Finding replacement components means searching salvage yards or paying premium prices for scarce inventory. Newer systems come with parts availability guarantees and longer warranty coverage, reducing future repair uncertainty.

Regular AC maintenance prevents most emergency breakdowns while extending equipment life. Professional technicians spot developing problems during routine service before they escalate into expensive failures. Coil cleaning, refrigerant level checks, and electrical testing catch issues at stages where simple adjustments prevent major repairs.

How Geothermal Systems Transform Home Comfort in Clayton, DE

Fri, 20 Feb 2026 14:53:22 GMT

How Geothermal Systems Transform Home Comfort in Clayton, DE

Geothermal heating and cooling in Clayton, DE taps into stable underground temperatures to deliver efficient year-round climate control for Delaware homes.

What makes geothermal different from traditional HVAC systems?

Geothermal systems use the earth as a heat source in winter and a heat sink in summer.

Unlike furnaces that burn fuel or air conditioners that fight outdoor temperatures, geothermal heat pumps exchange energy with the ground. Underground temperatures stay around 50-55 degrees year-round in Delaware, creating a stable thermal battery your system can access. This eliminates the wild efficiency swings typical systems face during extreme weather.

The technology works through buried loops filled with water and antifreeze solution. In heating mode, fluid absorbs ground warmth and concentrates it for your home. During cooling season, the process reverses—excess heat from your house transfers underground where earth absorbs it naturally. You get consistent comfort without combustion risks, carbon monoxide concerns, or outdoor units laboring against temperature extremes.

Do homeowners actually save money with geothermal installation?

Operating costs typically drop 30-70 percent compared to conventional heating and cooling equipment.

The exact savings depend on your current system's efficiency, home size, and usage patterns. Most Clayton families replace electric resistance heat, propane furnaces, or aging heat pumps—all expensive to operate. Geothermal systems move heat rather than generate it, requiring far less electricity for the same comfort level.

Equipment costs run higher upfront, but federal tax credits currently cover 30 percent of installation expenses. Delaware also offers rebates through utility programs and state energy incentives. Factor in decades of lower monthly bills, and payback periods often land between 5-10 years. The systems themselves can last 25+ years for indoor components and 50+ years for ground loops.

Beyond energy bills, you eliminate furnace repairs, AC condenser replacements, and the unpredictable costs that come with maintaining separate heating and cooling systems. One integrated system handles all your climate control needs.

Which homes work best for geothermal?

Properties with adequate yard space and existing ductwork see the smoothest installations and fastest returns.

You need room for ground loop installation—either horizontal trenches if you have open land, or vertical boreholes if space is limited. Most Clayton residential lots accommodate one method or the other. Homes with forced-air systems already in place require minimal interior work since geothermal heat pumps connect to existing ducts.

Older homes without ductwork can still benefit. Many homeowners pair geothermal with ductless mini split services in Clayton for efficient zoned comfort without extensive renovations. New construction offers the ideal scenario—ground loops installed before landscaping, with duct systems designed specifically for geothermal efficiency.

Soil conditions matter less than you might think. Delaware's geology generally supports both loop types, though your installer will conduct soil tests to determine the most efficient approach for your property.

How does Delaware's climate affect geothermal performance?

Moderate temperatures and high humidity levels in Clayton make geothermal exceptionally efficient compared to more extreme climates.

Delaware doesn't experience the brutal cold snaps that challenge northern geothermal systems or the scorching summers that strain southern installations. Your system operates in its optimal range throughout most of the year. The coastal plain geography provides stable subsurface conditions without bedrock complications that increase drilling costs in mountainous regions.

Summer humidity deserves special attention. Traditional air conditioners struggle with Delaware's muggy conditions, running longer cycles that spike electric bills. Geothermal systems excel at moisture removal because of their operating characteristics. The longer, steadier cycles pull more humidity from indoor air, improving comfort while using less energy than conventional cooling equipment cycling on and off.

Winter heating proves equally impressive. Even when surface temperatures drop below freezing, the ground maintains its thermal stability. Your system continues pulling heat from earth efficiently while neighbors' heat pumps labor or switch to expensive backup heating. This consistency eliminates the comfort swings and cost spikes common with other heating methods during cold snaps.

What happens during a geothermal installation in Clayton?

Professional installers complete site assessment, loop field installation, and system connection typically within 3-5 days for most residential projects.

The process starts with energy analysis of your home and property evaluation. Technicians calculate heating and cooling loads, determine optimal loop configuration, and identify the best location for ground loops based on your lot layout. They'll also review existing ductwork condition if applicable.

Ground loop installation represents the most visible phase. For horizontal systems, excavators dig trenches 4-6 feet deep in your yard. Vertical systems require drilling equipment to bore holes 150-400 feet deep, leaving minimal surface disruption. Both methods install high-density polyethylene piping that will outlast your house.

Once loops are placed and tested, crews connect them to the indoor heat pump unit. This equipment replaces your existing furnace and air handler, connecting to your ductwork or indoor air quality services in Clayton if you're upgrading ventilation simultaneously. Final steps include electrical connection, thermostat programming, and system testing to ensure peak efficiency before crews restore your landscaping.

Geothermal systems deliver reliable climate control through Delaware's changing seasons while reducing environmental impact and operating costs. The technology harnesses renewable energy already beneath your property for heating and cooling that keeps working efficiently year after year.

Geothermal Systems Deliver Sustainable Climate Control in Smyrna, DE

Geothermal systems in Smyrna, DE harness stable underground temperatures to deliver efficient heating and cooling with minimal environmental impact and long-term energy savings.

How do geothermal heat pumps work?

Geothermal heat pumps circulate fluid through underground loops to absorb earth's constant temperature, then transfer that energy into your home for heating or cooling.

Below the frost line, soil temperatures remain steady year-round, typically between 50 and 60 degrees. During winter, the system extracts heat from the ground and moves it indoors. In summer, the process reverses, pulling heat from your home and depositing it into the cooler earth.

This heat exchange uses electricity only to run circulation pumps and compressors, not to generate heat or cold. That efficiency translates to up to 50 percent lower energy costs compared to conventional HVAC systems. Because you're moving existing heat rather than creating it, geothermal systems produce fewer greenhouse gas emissions.

Which properties in Smyrna benefit most from geothermal?

Homes with adequate lot size for loop installation, high heating and cooling demands, and long-term ownership plans see the greatest return on geothermal investment.

Geothermal loops require horizontal trenches or vertical boreholes depending on your property layout. Larger lots accommodate horizontal systems more easily, while smaller parcels may need vertical drilling. Either method works well in Smyrna's soil conditions, which provide good thermal conductivity.

If you plan to stay in your home for many years, the upfront installation cost is offset by decades of reduced utility bills and minimal maintenance. Geothermal systems also increase resale value by appealing to eco-conscious buyers seeking energy-efficient features. You can discover more about financing options in Smyrna, DE to make your transition to sustainable climate control more affordable.

What maintenance do geothermal systems require?

Geothermal systems need annual inspections of fluid levels, pump operation, and filter changes, with underground loops typically lasting 50 years or more without intervention.

Indoor components such as heat pumps and air handlers require the same routine care as conventional HVAC equipment. Technicians check refrigerant charge, inspect electrical connections, and clean coils to maintain peak efficiency. The underground loop itself is remarkably durable, with sealed pipes resistant to corrosion and leaks.

Because geothermal systems have fewer moving parts and no outdoor condenser exposed to weather, they experience less wear than traditional air conditioners and furnaces. This reliability reduces repair costs and extends system lifespan well beyond standard equipment.

How does Smyrna's climate suit geothermal technology?

Smyrna's moderate winters and humid summers create ideal conditions for geothermal systems, which excel at managing both heating loads and dehumidification needs.

Delaware's temperate climate means your geothermal system rarely faces extreme demands, allowing it to operate in its most efficient range throughout the year. Unlike air-source heat pumps that struggle in subzero temperatures, geothermal performance remains consistent because underground temperatures stay stable.

Humid summers also favor geothermal systems, which naturally dehumidify indoor air as they cool. This dual action improves comfort without the energy penalty of separate dehumidification equipment, a significant advantage for homes near me in Smyrna.

Indoor Air Quality Testing Uncovers Hidden Pollutants in Middletown, DE Homes

Thu, 22 Jan 2026 14:30:01 GMT

Indoor Air Quality Testing Uncovers Hidden Pollutants in Middletown, DE Homes

Indoor air quality testing in Middletown, DE uses comprehensive assessments to detect airborne pollutants like mold spores, volatile organic compounds, and particulates that trigger health symptoms.

What symptoms suggest poor indoor air quality?

Frequent headaches, respiratory irritation, persistent allergies, and unexplained fatigue often indicate elevated levels of indoor pollutants affecting your household.

Many homeowners dismiss these symptoms as seasonal allergies or stress, but they may stem from contaminated air circulating through your HVAC system. Pollutants such as dust mites, pet dander, and chemical vapors accumulate in ductwork and get redistributed with every heating or cooling cycle.

Children and elderly family members are especially vulnerable to poor air quality. If symptoms worsen at home but improve when you're away, testing can pinpoint the source and guide effective remediation.

How does professional air quality assessment work?

Technicians use calibrated sensors and air sampling devices to measure particulate levels, humidity, carbon dioxide, volatile organic compounds, and biological contaminants throughout your home.

Testing begins with a walkthrough to identify potential pollution sources such as cleaning products, off-gassing furniture, or moisture-prone areas. Sensors placed in multiple rooms capture data over several hours to account for daily activity patterns and HVAC operation.

Lab analysis of air samples reveals specific pollutants and their concentrations, allowing you to address the most significant threats first. You can explore indoor air quality services in Middletown, DE to understand the full scope of testing and remediation options.

Can HVAC systems worsen indoor air quality?

Yes, dirty ductwork, moldy coils, and clogged filters turn your HVAC system into a pollutant distributor, spreading contaminants into every room.

When moisture accumulates on evaporator coils or in drain pans, mold colonies grow and release spores into your airflow. These spores trigger allergic reactions and asthma symptoms in sensitive individuals. Regular coil cleaning and drain maintenance prevent biological growth and keep air fresh.

Filters beyond their replacement interval lose effectiveness and allow dust, pollen, and fine particulates to bypass the filtration system. Upgrading to higher-MERV filters captures smaller particles but requires compatible airflow capacity in your system to avoid strain.

Which Middletown neighborhoods face higher air quality risks?

Older homes in established Middletown neighborhoods often have sealed construction that traps pollutants, while newer developments near busy roads face elevated outdoor particulate infiltration.

Homes built before modern ventilation standards may lack adequate fresh air exchange, causing indoor pollutants to accumulate over time. Radon, a naturally occurring radioactive gas, can also seep through basement foundations in certain Delaware soil conditions, requiring specialized testing and mitigation.

Properties near highways or industrial zones experience higher levels of outdoor pollutants that enter through windows, doors, and HVAC intakes. Testing helps you understand your specific risk profile and choose appropriate filtration and ventilation upgrades.

Protecting your family's health starts with understanding what you're breathing every day. EnviroTemp provides thorough air quality assessments and practical solutions, including HVAC services near me in Middletown, DE to improve your home's environment.

What To Do If HVAC Exhaust Smells Like Gas

Tue, 02 Dec 2025 18:08:03 GMT

Is It Normal To Smell Gas When Hvac Is Running?

Residential furnaces that are powered by natural gas are one of the most common types of home heating systems in the area. Sometimes with these systems, there can be a malfunction which may lead to funny smells coming from your vents or around the furnace. Though it is uncommon for the system to produce a gas smell, it is important to know what to do if it happens, as this could be a very serious concern.

Propane (LP) gas: You have this type if your gas comes from a tank located outside close to your house. Propane is stored as a liquid under pressure in tanks and cylinders. In most residential applications, propane is used as a vapor. When liquid propane changes into a gas vapor, it expands in volume. This means that even a small leak of liquid propane can result in a much larger quantity of propane vapor, which can be especially dangerous in a confined space. A chemical odorant has been added to propane to give it a distinct smell. Learn to identify this odor. Propane gas is heavier than air, so it will sink to the floor and spread. To check for the presence of propane, carefully smell all over a room, especially in low spots.

If you smell propane (LP) gas:

Exit your home immediately.
Propane gas can ignite easily. Do not light a match, start an engine, use a cell phone, or do anything that may create a spark.
From a safe area, contact your propane supplier and call 911.
If you are able, shut the propane gas supply off at the tank.
Stay away from your home until you've been told that it is safe to return.

Natural gas: You have this type if you have a gas meter and pay a natural gas supplier or utility. A chemical odorant has been added to natural gas to give it a distinct smell. Learn to identify this odor. If you smell gas faintly, check all areas of your house for strong odor. If the smell is only faint throughout all areas of your home, call your heating contractor to get it fixed within 24 hours. Keep the house well ventilated by opening windows.

If you smell a strong, persistent odor:

Exit your home immediately.
Do not light a match, start an engine, use a cell phone, or do anything that may create a spark.
From a safe area, contact your gas company or call 911.
If you are able, turn the gas off at the meter.
Stay away from your home until you've been told that it is safe to return.

How Does 2-Stage Cooling Or Heating Work?

Tue, 02 Dec 2025 17:44:50 GMT

2-stage cooling is a method of cooling that can better manage the cooling of your home while outdoor temperatures are changing. It can also better maximize indoor comfort and energy efficiency. 2-stage cooling systems are typically the most energy efficient systems out there.

2-stage cooling can be done by having one unit with two compressors, one small and one large. The small one is typically capable of putting out about 50% the capacity of the larger one. The second way to have 2-stage cooling is to have a single scroll unloading compressor. This compressor can unload its capacity down to about 66% of maximum capacity. Both these methods of getting 2-stage cooling allow the unit to run at a lower stage when the high stage is not needed. By doing this, energy is saved.

2-stage heating has the same principle as 2-stage cooling. It allows the unit to adjust itself based on the amount of heating that is necessary. 2-stage heating is a good way to save on heating costs.

A heat pump system would have two different sized compressors, a small and a large one. The compressor that is used at a given time would depend upon the need. If only a small amount of heating is necessary, the smaller compressor would be used to save energy. The large compressor would only be used when a large amount of heating was needed.

A gas furnace that is 2-stage has a modulating gas valve that regulates gas flow depending upon the need.

Ductless Mini-Splits Vs Central Air Conditioner - Which Is Best?

Tue, 02 Dec 2025 16:55:12 GMT

When it comes to ductless mini-split air conditioners vs central air conditioning, there are a lot of factors to consider. Both have their pros and cons, and the best option for your home will depend on your specific needs. In this article, we will take a look at both ducted and ductless AC systems and help you decide which is the best option for you.  Envirotemp has worked in numerous Clayton, Delaware homes that do not have a traditional furnace. During the harsh winters, homeowners used baseboard heat or a boiler to get by.  When it's hot outside with no air conditioning, there aren't many options. You open windows at night, close shades on the east and west sides of the property on sunny days, turn up the fans to maximum speed, and gather around room or window air conditioners.  If the Clayton summers are making you yearn for air conditioning, and you don't currently have a duct system, there are two viable alternatives.  Install a forced-air cooling system - an air conditioner or heat pump - or invest in a ductless mini-split system.  Don't know which option is cheaper? Are you curious about the installation process? Or how each one will change the appearance of your house? We'll answer these and other questions at the conclusion of this essay, and we hope to assist you in selecting how to keep your home cool.

If You Already Have Ductwork

The first course of action is simple if you already have ductwork. The external device will require power, and a line set will be required to bring conditioned air down to the basement or lower level. After that, an air conditioner must be installed to push the cooled air throughout the house.  Because the ducts will most likely reach all of the rooms, chilly air will be available in every location. All you have to do now is purchase an air conditioner or a heat pump, and you'll be well on your way to a more pleasant summer. In addition, both of these devices help to remove humidity from the internal air, resolving:

An overly warm top floor or finished attic
Musty and disgusting smells
Mold showing in damp areas
Family having breathing issues
A general decrease in comfort
Permanent window fog
Different floors are often completely different in temperature
Spiders, bug infestations, and cobwebs
Wooden furniture experiencing moisture damage
Water stains

Ductless mini-splits can be used in conjunction with central ductwork if it is already in place. However, they would be utilized room by room rather than as a whole-house remedy.

If You Don't Have Ductwork

Ductwork installation is time-consuming and expensive. And that doesn't include the price of a new air conditioner or heat pump.  An HVAC technician will need to design a ductwork system to cover the entire house. To all of the rooms, the ductwork will need to be retrofitted.  Then you have to factor in the cost of installing an air handler, air conditioner, heat pump, or gas furnace and air conditioner.  It's not difficult to install whole-home ductwork in a ranch house with a full, unfinished basement. You may run the ductwork wherever you want.  If you have multi-levels, a basement, or a finished basement, it'll be extremely invasive. The ductwork will need to pass through finished rooms. There will be cutting and moving and refinishing. It becomes filthy and expensive.  You cut out a space for the supply and return ducts in a closet or the nook of a room. Then it's time to bring it up to the attic. It's going to set you back some cash. After all that work, you'll need to finish the job afterwards.

How Long Would It Take To Install Ducts For An Unfinished Basement In A Ranch Home?

It might take two to four days to complete the whole system. The process of running ductwork is time-consuming. Installing the AC and air handler would take another six to eight hours.  We may always add a zoned system as we go. Electronically controlled dampers are an option for a zoned system. These can be partially closed to aid in the restriction of air movement into a specific room. The air pressure throughout the rest of the home would rise as a result of this.

Why Is Ductwork So Expensive To Install?

A basement run takes only a few minutes. However, you must cut the floor holes for supply and return registers. You must cut the holes for the return registers. Flex-duct is used by some businesses. You just pull it out and tie off each end, and you're ready to go.  Sheet metal ductwork is used at Envirotemp since it promotes airflow more than ribbed, flexible ductwork. It also takes a bit longer to install.  We can't give a price since we'd have to run a lot of duct and make a lot of holes. The final work would need to be completed by another contractor.  The cost of a whole-house duct system can range from $6000 to $15,000. That's starting at the low end for a baby ranch house with a small main trunk system.

Advantages Of Installing Central Air Conditioning

Central air conditioning is your quickest, simplest, and most affordable way to cool your house if you already have existing ductwork.  The disadvantage is that you'll have to run ductwork throughout the house. The advantage is that you'll be able to reach each room if you must install ductwork in the whole home.  By using central air, you may quickly add equipment to improve the air quality. Humidifiers can make the dry winter months more enjoyable. Air purification systems can get rid of germs, odors, allergens, pet dander, and other pollutants. Your entire home will be healthier and cleaner as a result of this renovation project.  The cost of an air conditioner unit is less than that of a ductless. The cost of a new AC for a house ranges from $4,500 to $13,000. This covers labor and regulatory costs. Variable-speed AC systems are among the different system sizes and levels of sophistication covered by this range.  If you're leaning towards a heat pump, the cost is comparable. The price of a new heat pump ranges from $4,900 to $12,500. This time period covers the equipment expense, labor costs, and any other expenses. This range includes variable-capacity heat pump systems in a variety of system sizes and degrees of sophistication.  A typical air conditioner costs between $2900 and $5800. This fee includes installation. The price variation is due to the unit's capacity and type of blower it has. Heat strips are another $300 to $600 in addition to the unit's price.

Disadvantages Of Installing Central Air Conditioning Without Ducts

A duct may have to run through your living room. Installers will cut two holes in the floor and run ducts throughout in order for it to function. It will be intrusive.

Let's pretend we're examining a fully completed basement in a three-story home. What would happen?

We have to either run the ductwork beneath the existing finished ceiling in the basement to install supply registers on the first floor. Alternatively, we'll have to run the ducts above the completed ceiling or rip out the ceiling to place them up in the joist space. Another contractor will need to clean up any holes we make.

If we want to get to the second floor, we'll either have to climb up the walls and across the ceilings of the first floor. Then there's another set of holes. We'll also need to create holes for both supply and return air.

Unless you've got the system zoned, you'll have to choose where to put a thermostat. The thermostat does not know what temperature is in every room. Air conditioning can be used with zoning, but it isn't as efficient as ductless mini-splits for zoning.

Advantages Of Ductless Mini-splits

They are less invasive. They may enter areas where there are no existing ducts. This can't be overstated. Ductless mini-splits have a flexibility central air conditioning doesn't come close to matching..
Each head is picked to whatever temperature you choose. (One note of caution: They all must be set to cool or warm. You can't have one that's cooling and another that's heating.)
In most cases, they are. The head is installed on the wall, and a small hole is cut in it for the refrigerant line. We conceal that refrigerant line because it is hidden behind a line hide.
The process of connecting ductwork to the system is far faster than that of installing ducts. You'll have immediate heating and cooling just as you wish, and you may manage the units using your phone with the mobile app. (You can do this with a high-end AC/heat pump and thermostat, too.)
They heat and cool. Yes, A heat pump can do the same, though they will struggle during extreme cold.
Ductless technology is one of the most energy-efficient technologies available. The lower end of ductless systems has a SEER rating of 16 - 18. Some of the more expensive devices reach into the 30s. There is no way that an air conditioner or heat pump can compete with these products when it comes to efficiency. A higher SEER rating is preferable, and it consumes less power.
Ductless heating/cooling systems are simpler to regulate since they don't need a main supply line. You can set the temperature on each head individually.
Variable-speed compressors are common in small-capacity mini-splits, allowing them to run as much or little as necessary. In contrast to most (but not all) central air units, which have only one or two speeds and must be switched on and off more frequently.

Disadvantages Of Ductless Mini-splits

You won't be able to perform complete-house humidification, air purification, or dehumidification with ductless. The ductless system includes some humidity and cleaning abilities. (The ductless does include some dehumidification and filtering capabilities.)
Some people can't get over that thing on their wall. No question that it will be obvious in every room in which it's mounted, whereas vents can be more unobtrusive.
You need a ductless air conditioner with heat strips if you have no ducts or don't want to use them. They're efficient when it comes to heating, but there's no backup heat. When it gets really cold, you'll wish you had an air handler with electric heat strips and some emergency heat. A long period of intense cold will significantly increase your electricity bill.
Central airflow is not created by ductless. It does not move air throughout the property, resulting in unventilated rooms that will not receive conditioned air. Only specific areas will be cooled/heated to precise comfort levels.

The Next Step Is Up To You

It's a difficult choice between running ductwork and installing centralized air conditioning in a retrofitted home without ducts. You must compare both alternatives and choose the one that is best suited to you. In general, a ducted system in the basement is generally more appealing than a ductless mini-split system in a house with a full basement and just one floor.

If you have multiple levels and no locations where ductwork may be run, ductless technology may be a more appealing option.

You should now have a much better notion of which option is right for you. For others, the answer may be a combination of both, with a central air system servicing the majority of the property while a mini-split unit serves a specific area or room that is difficult to heat and cool.

How To Resolve Common Gas Propane Furnace Problems

Tue, 02 Dec 2025 16:00:05 GMT

The four most prevalent furnace issues are listed below. Continue reading to learn how to repair many of them, as well as what you can do to prevent future furnace issues.

After you troubleshoot your system and still need professional help, schedule a furnace repair today!

No Heat

One of the most typical furnace problems is a lack of heat. There was no one single problem that caused the lack of heat, so you'll need to examine everything carefully to discover what's wrong.

Adjust the thermostat if necessary. To begin, check the thermostat. The heat may have been switched off or set to a low level. If this is the case, adjust the thermostat's temperature setting.

If it's not a thermostat problem, check to see whether the propane valve is closed. If the valve is shut, no gas can enter the furnace to warm up the air. If you discover that it is shut, you may either open it yourself or seek help from a professional if you need it.

The third possible problem is a blown fuse. This fuse will need to be changed. You'll need to book an appointment for a gas heater repair to do so.

When it comes to propane, always exercise caution. With interactive safety training that the entire family can grasp, educate your children.

Lastly, if your furnace has a pilot light, check to see whether it's on by peering into the tiny window at the front of the unit. The flame should touch the end of the thermocouple. Check to see if your furnace is turned on using an electronic ignition instead of a pilot light.

The Fan Is Not Running

If your furnace's fan isn't working, check the inspection window on the blower compartment of the furnace first.

Is there a blinking green light? If that's the case, go on to the next technique for repairing your heating system.

If the light is red or nothing at all, your heater may have a problem with the transformer, control board, blower motor, or run capacitor.

If you saw a green light, check the breaker. If it's tripped, look for loose wiring or burned areas on the control board. Do not reset the breaker until a competent specialist has addressed these concerns.

Blower Does Not Turn Off

Suddenly, you discover that your gas furnace's blower has been on continuously for an hour or more. What do you do now?

Do some troubleshooting to determine if it is the setting or the fan that is the problem.

Check the thermostat to see whether your fan is on continuously. The blower should not be on 24 hours a day, seven days a week; It needs time to cool down between uses. Set your thermostat to automatic so that the blower can turn on and off as needed.

The other reason the blower won't turn off is because of a faulty control switch on the fan. If you can reach it, check that the switch for turning off the blower is in good working order.

Furnace Turns On And Off Too Often

A gas furnace should turn on and off throughout the day. If it's turning on and off too frequently, that might indicate a problem.

The issue could be the thermostat, air filter, belt or blower motor.

Check the filter and thermostat first. Replace a dirty air filter if necessary. A clogged air filter can cause frequent on-off activity. Check the thermostat to be sure it's set to auto as well. If the thermostat shows on, high or continual, change it to auto

If the problems listed above still aren't alleviated, it's time to call your furnace repair company. The problem may be more difficult than this, such as a worn belt or incorrect tension, or motor ports might need to be lubricated.

Maintenance Tips For Your Furnace

Get in the habit of having your gas furnace serviced on a regular basis to avoid many of the issues it may experience. Get in the habit of scheduling maintenance by a professional trained expert. During these visits, your repair person will look for and address any problems before they become serious.

Contact a furnace repair firm at the end of summer or the start of fall to come to your property and fully inspect and repair your heating system.

Regular maintenance visits ensure your heating system is in tip-top operating order and reduce the likelihood that you will wake up to a chilly house in the middle of winter.

Prevention is often much less expensive than repairs after neglect.

You should also schedule maintenance visits on a regular basis, as they are important for the long-term health of your chimney. There are certain maintenance activities that you can accomplish yourself during the duration of the professional visit. For example, change the air filter on a regular basis. Follow the manufacturer's instructions regarding how often you should change the filter and do so accordingly.

Check and replace the battery on your thermostat every spring and fall.

If you smell gas, contact your propane supplier immediately.

Envirotemp Can Help

When troubleshooting your furnace problems, never hesitate to contact a trained professional.

All furnaces, even new ones, could pose combustion or other safety hazard risks. It's always best to have a specialist take a look and suggest the right solution.

Don't block vents in well-used rooms - Keep your supply and return air vents free of objects like blinds, carpets or furniture so your furnace can operate efficiently and there is even heat distribution.
Install ceiling fans - Change the direction of airflow on your ceiling fans. In the winter, the blades should operate in a clockwise direction helping to push the warm air from the ceiling down into the room.

Should I Repair or Replace My HVAC System?

Tue, 02 Dec 2025 15:55:25 GMT

Does My Ac System Need To Be Replaced Or Can It Be Fixed?

When contemplating whether to repair or replace your HVAC system, there are a few factors to consider. Although repair may seem like the cheaper fix, it isn't always the best option for your home. There are pros and cons to both repair and replacement, and we hope to help make your decision easier with these things to evaluate!

Repair

Depending on your situation, repairing your AC system can be the best solution. Typically, repair is the cheaper option when compared to replacement. Who doesn't love to save money? One thing to understand in your decision to repair or replace is if repair is actually cheaper in the long run. Will this repair be a temporary fix? Does your system have frequent breakdowns? Your heating and cooling unit is much like your car. When your car breaks down, you take it to the body shop and have it fixed. If the car repair is unfixable or costly, buying a new car is a possible solution.

Replace

Unfortunately, even heating and cooling units have an expiration date. Replacing your HVAC system is an investment, but it does have benefits. If you are in the market to replace, your current system is likely causing you stress from breakdowns. Replacing as a whole can give homeowners peace of mind knowing they have a reliable unit in the summer and winter months. New HVAC units have higher efficiency which increases your overall comfort.

Things To Consider

We encourage you to consider these factors when deciding to repair or replace your HVAC system.

The Age Of Your Unit.

HVAC systems typically last 10-15 years with proper maintenance. The chance of breakdowns and frequent repairs increase after your unit hits the 10 year mark. Considering this, if your unit is 10 years or older it is likely to continue needing repairs until it eventually gives out. Frequent repairs and technician calls can be expensive, which makes replacement a good option.

The Cost Of The Repair.

Many HVAC technicians use the "$5,000 rule." This rule of thumb multiplies the age of the unit by the repair cost, and if the total exceeds $5,000 it may be best to replace the unit. If the repair is inexpensive and your technician recommends this as the best option, repair could be your best choice.

The Efficiency Of Your Unit.

Ask your Envirotemp technician to evaluate your unit's Seasonal Energy Efficiency Ration (SEER) rating. The higher the SEER rating, the more efficient your unit is. This rating can help determine your possible savings by replacing your unit.

How Long Will You Live In Your House?

Evaluate how long you plan on living in your home before buying a new unit. If you plan on living there for many years to come, replacement could be beneficial. If you are selling your home, a new HVAC unit can increase your resale value and many buyers ask for replacement.

The Cost Of Your Energy Bills.

Older units may be the cause of high utility bills due the amount of energy they use. New units are more energy efficient, which can reduce your monthly energy bill.

Best Air Purifying Plants (And How To Keep Them Alive)

Tue, 02 Dec 2025 15:53:38 GMT

Six Plants That Improve Air Quality

Plants help improve air quality in many ways such as absorbing carbon dioxide and releasing oxygen through the process of photosynthesis. Additionally, some plants can naturally purify the air you breathe. If you are looking for continued ways to decrease allergens and harmful toxins from the air, consider placing a few air purifying plants in your home. In this blog, we will highlight six air purifying plants and their benefits. Don't worry, for those that do not have green thumbs, we will explain how to keep them alive!

Benefits Of Indoor Plants

Helps us breathe easily. Plants have the ability to create oxygen, which is vital to clean air and obviously human life. While plants use the process of photosynthesis, they are in taking carbon dioxide and releasing oxygen, which is an equal process for humans releasing carbon dioxide and inhaling oxygen.
Purifies air. A study done by NASA revealed that houseplants can remove toxic vapors in enclosed buildings. NASA also concluded that plants can reduce dust levels by up to 20%. Dust reduction is beneficial for residents with asthma or allergies.
Improves health. Plants increase the humidity of the air, which isn't always a bad thing in Delaware! Humidity in your air can have multiple health benefits such as preventing dry throats and reducing the likelihood of allergies.
Cost effective. Plants are the natural comparison to an air purifier and can be the cheaper option if properly taken care of.

Why Is My AC Freezing Up?

Tue, 02 Dec 2025 15:43:46 GMT

Everything You Need To Know If Your Air Conditioner Freezes In The Summer

Although many love the summertime, it is nice to know you have a cool getaway from the heat waiting for you inside your home in Dover, Delaware and surrounding areas. To ensure the comfort of air conditioning is waiting for you at home, it is important to make sure your unit is running properly. A common homeowner repair in the summertime is a frozen air conditioning unit. Many do not understand how 80 degrees and above can allow your condenser to freeze up, but trust us - it is possible! In this blog, we will answer the common homeowner question of "Why is my AC freezing up," and how to proceed.

What Causes An Air Conditioner To Freeze?

To understand why your air conditioner is freezing up, let's start with the basics. Your AC unit's main parts are a compressor, evaporator coil, condenser coil, and refrigerant. Each plays a vital role to maintain your comfort. Your air conditioner collects all the warm air from your home, which blows over the evaporator coils. The refrigerant is found inside both condenser and evaporator coils and works to remove heat and moisture. If warm air does not reach the refrigerant, it becomes so cold that the excess moisture on the coils freezes. Your air conditioner is freezing up because of lack of airflow to your coils, where your refrigerant lies. Fix your airflow and you will no longer have a frozen air conditioner.

How Do I Fix A Frozen Air Conditioner?

In most cases, you are able to defrost your AC unit by yourself. Switch your thermostat to the "off" setting and turn the fan setting to "on." These two steps will power off your air conditioner and help blow warm air over the frozen coils. However if there is frost on your fans, skip switching your fan setting on due to possibly delaying the process. Dethawing your air conditioner can take up to 24 hours, so make sure you are prepared to maintain comfort in another way. While the unit is defrosting, try to find the source of the problem. We have listed common reasons your air conditioner froze in the section below. After your air conditioner has thawed, turn your air conditioner back on and monitor it closely. Give us a call if the problem arises again to identify the issue!

Reasons Your Air Conditioner Froze

It sometimes seems like your air conditioner picks the hottest and most humid day to need repairs. Here are the common reasons for air conditioners to freeze up:

Dirty Air Filters
Clogged Drain Lines
Faulty Blower Fan
Low Refrigerant
Blocked Air Vents
Dirty Air Filters

Your air filter can be the reason your air conditioner has many problems. Debris such as pollutants and dust can clog your air filter and make it difficult for air to flow through. If the outside of your air filter vent has dust, it is likely your air filter needs to be changed. Airflow begins with your air filter, so start here if your air filter is frozen.

Clogged Drain Lines

While your air conditioner removes heat, it also removes moisture. Moisture exits through a copper or PVC drain line pipe typically near your outdoor unit. Drain lines can become clogged by a buildup of mold, mildew, and debris. If your drain line is blocked, water can become trapped near the evaporator coil and freeze.

Faulty Blower Fan

The blower fan is designed to blow warm air to the coils. If the blower fan is damaged or malfunctioning, there is a lack of airflow and your air conditioner can freeze.

Low Refrigerant

Low refrigerant is a common cause of a frozen air conditioner due to the coil pressure. Low refrigerant leads to low pressure, which allows moisture in the air to accumulate and freeze on the coil. If your air conditioner is low on refrigerant, there is likely a leak which should be addressed by a professional.

Blocked Air Vents

You should not be closing or placing furniture over your air vents. Your airflow will decrease and can cause problems such as air duct leaks and frozen air conditioner coils. Avoid obstructing air coming out of your vents to prevent a frozen air conditioner.

If your air conditioner is not frozen due to any of these issues or continues to freeze, give us a call at (302) 653-4073! We are not comfortable until you are and can help solve any issue with our air conditioning services in Clayton.

Ways To Boost AC Efficiency

Tue, 02 Dec 2025 15:42:34 GMT

Your cooling system is a large part of your energy bills each month, especially in the summer. Your air conditioner is working hard at all hours of the day to keep your home a comfortable temperature. However, if your air conditioner is well maintained your bills can be lowered. In this blog, we provide a few ways to boost AC efficiency to keep your air conditioner working properly and save you money this summer.

Save Money And Energy!

Below are 8 simple ways to improve your AC efficiency while keeping cool all summer long.

Keep Clean And Clear Vents
Shut All Windows
Clean Outdoor Unit
Boost Your Thermostat Temperature
Utilize Blinds And Curtains
Maintain A Clean Air Filter
Perform Regular Maintenance
Clear Drain Line

Keep Clean And Clear Vents

To increase your air conditioner's efficiency, ensure all air vents are open and free of any items blocking them. Furniture blocking your air vents can create pressure in your ducts and lead to air leaks. Vents can also cause molding on your furniture if they are placed over them. Cleaning your air vents free of dust and debris will help your air conditioner easily push air through, and result in better air quality.

Shut All Windows

As nice as a summer breeze can be, it can threaten your air conditioner's efficiency and raise your utility bills. Open windows alter the room's temperature, which causes your air conditioner to work constantly to meet the thermostat setting. Your cooling bills will rise due to the amount of energy used if windows are open.

Clean Outdoor Unit

Your outdoor unit can collect debris from the weather. Your air conditioner's efficiency levels and airflow will rise if you ensure your unit is clear of branches, grass clippings, leaves, and other debris each week.

Boost Your Thermostat Temperature

Your air conditioner works hard all day long to keep up with cooling demands. If your home will be vacant for the day, consider turning your thermostat up a few degrees. You will save on cooling costs, and your home will stay at a comfortable temperature if altered by 5-8 degrees. A programmable thermostat can automatically alter your temperature due to previously programmed settings, and could be a good investment to increase your home's efficiency.

Utilize Blinds And Curtains

Sunlight can add unwanted heat to your home during the day and cause your air conditioner to work harder. Utilize your blinds and curtains to block out sunlight and decrease heat gain.

Maintain A Clean Air Filter

Your air filter determines your air conditioner's performance. If dirty, it harms airflow, efficiency, and air quality. Your air conditioner struggles to push air through a clogged air filter, which causes it to overwork itself and raise your energy bills. Be sure to change your air filter every 3 months to maximize your AC unit's efficiency.

Perform Regular Maintenance

Much like your car, your air conditioner needs maintenance twice a year. We recommend scheduling preventative maintenance in the spring and fall to prepare for the weather the upcoming seasons will bring. Your Envirotemp technician can ensure your air conditioner is working properly and efficiently.

Clear Drain Line

Your air conditioner also removes humidity while cooling your home. The excess moisture exits out of the drain line, which can clog from time to time. A clogged drain line can decrease your AC unit's efficiency and cause a leak. Your Envirotemp technician can help you locate and clear your drain line, give us a call!

Consider these 8 ways to boost your air conditioning efficiency to keep your home comfortable and your cooling bills low. Give us a call with any air conditioning repairs in Clayton or to schedule your fall maintenance today!

AC Repair: DIY Vs. Calling A Pro

Tue, 02 Dec 2025 15:34:48 GMT

Your air conditioner is an important appliance in your home and should be properly taken care of. While DIY projects can be beneficial and efficient, we recommend leaving the complex AC repairs to the experts at Envirotemp. Homeowners are encouraged to do tasks that help their air conditioner function properly, but not attempt to fix a broken unit. In this article, we will explain the importance of calling an AC professional rather than fixing your air conditioner yourself.

Why You Should Call A Professional

Air conditioning repair can be a complicated process. Most repairs require certain tools that most do not keep in their tool box, along with knowledge only trained professionals hold. Below are 5 reasons you should call a professional.

Safety
Reducing Efficiency
Creating Bigger Problems
Warranty
Equipment

Without a trained eye, attempting to repair your unit can do more harm than good and possibly create more repairs. Some repairs deal with electric wiring and can risk safety if not handled properly. We don't expect you to be the expert, that is what we are here for!

What You Can Do For Your Unit

To ensure you don't do more damage, it is important to know which tasks you can do yourself. Below we have listed a few maintenance tips homeowners can do to help your air conditioner perform efficiently and prevent repair!

Regularly Change Air Filters

Your air filter can determine how your system functions and could be the source of many problems. It is important to change your air filters every 3 months to keep your air conditioner running efficiently and effectively.

Keep A Clean Outdoor Unit

Your outdoor unit endures the weather and can build up debris. Debris such as grass clippings, leaves, branches, and trash can accumulate on your air conditioner and harm efficiency and airflow. We recommend checking the status of your outdoor unit weekly to ensure its health and performance.

Ensure Good Air Flow

The air vents in your home should remain open and unblocked for better airflow and efficiency. Blocked or closed vents can cause air leaks in your ducts from the built up pressure, resulting in high energy bills and possible repair.

When To Call A Professional

Certain AC repairs should be handled by a professional to ensure your safety and protect your air conditioner. Rather than attempting to identify and fix the problem, below are signs you should call a professional.

Unusual Noises

It is normal for your air conditioner to make noises from time to time, but not constantly. Unusual noises can indicate your air conditioner needs repair soon. Below are 3 noises to pay attention to:

Banging/Clanking: This typically indicates there is a loose part, which could cause more damage if ignored.

Buzzing: Buzzing means there is a malfunction within your system, such as the compressor or condenser fan.

Squealing: If your unit is squealing, it may be an issue with your blower fan.

Warm Air

Warm air blowing from your air conditioner is just about as uncomfortable as no air. A common cause to an AC unit blowing warm air is low refrigerant, which is a toxic fluid. Refrigerant poisoning can lead to difficulty breathing, headaches, and other problems. For your safety, call a professional rather than attempting to repair a refrigerant leak.

Insufficient Airflow

If your air conditioner is not adequately cooling your home, it could mean a variety of repairs. Your AC unit is likely working overtime to meet the cooling needs of your home, which raises utility bills. Rather than finding the source yourself, we can quickly identify the issue and restore airflow!

For all air conditioning repairs and maintenance, we recommend calling one of our trained technicians to help resolve your issue. Repairing your AC unit yourself can lead to more issues and risk your safety. We are here for you and are not comfortable until you are!

Benefits Of a Whole Home Dehumidifier

Tue, 02 Dec 2025 15:26:36 GMT

While Delaware being surrounded by water has its perks, it also has negatives like high humidity. Homeowners in Delaware should be aware of humidity levels inside their homes, because of the damages it can cause. If your home has high humidity, we recommend investing in a dehumidifier. In this article, we will explain the benefits of a whole home dehumidifier and why it is necessary in your Delaware home.

What Is A Whole Home Dehumidifier?

A whole home dehumidifier is a device that removes moisture from the air in every room of your home. They function similarly to a regular dehumidifier, but protect each room rather than single rooms. If your home has ever felt uncomfortably hot and muggy, chances are humidity levels are high. Your HVAC units work to remove humidity, but when levels are high it struggles. A dehumidifier provides many benefits to your home, such as reducing workload for your HVAC system.

Why Do I Need A Dehumidifier In Clayton?

Delaware has a humid and temperate climate. There are some high humidity months and some lower. To put into perspective, homes should be kept between 30-50% humidity and the lowest humidity month in Delaware is about 53%. If your home has high humidity, it can damage many components and cause discomfort. Dehumidifiers can remove extra moisture from the air and greatly improve indoor air quality.

Benefits Of A Whole Home Dehumidifier

A dehumidifier can improve comfort and protect aspects of your home. Both portable and whole home dehumidifiers can be beneficial, but the whole home device can protect every room at once. Below are 5 advantages of a whole home dehumidifier.

Reduces Utility Bills
Increases Home Protection
Improves Comfort
Prevents Mold Growth
Improves Energy Efficiency
Reduces Utility Bills

Your HVAC unit works to remove humidity, but can become overworked if levels are high. A whole home dehumidifier can take some of your HVAC unit's workload, which reduces energy usage and saves money on monthly utility bills.

Increases Home Protection

High humidity can cause damage to many aspects of your home. The moisture in the air can cause:

Damaged electronics
Warped wood floors & furniture
Peeled paint & wallpaper
Mold and mildew growth

A dehumidifying system can remove excess moisture and protect your home from the damages it may cause.

Improves Comfort

Homes with high humidity can feel uncomfortable and sticky. A dehumidifier is the quickest and easiest solution to restoring comfort. A whole home dehumidifier can ensure each room has an appropriate level of moisture to maximize comfort.

Prevents Mold Growth

High humidity can cause mold and mildew growth in your home, because the pollutants thrive in warm and moist environments. A whole home humidifier can remove moisture from every inch of your home to prevent mold growing in the future.

Improves Energy Efficiency

If your home has high humidity, your HVAC system is working hard to remove it. However, removing moisture is not a heating and cooling unit's main task. A whole home dehumidifying system can help the workload of your HVAC unit and reduce energy usage.

A whole home dehumidifier can help you breathe cleaner, healthier air while providing multiple other benefits. The fall season is the perfect time to consider having a dehumidifier installed, because it will help remove pollutants and keep seasonal allergies to a minimum.
