New Year, New Rules: What the End of Federal HVAC Tax Credits Means for Your 2026 Upgrade

Written by Kevin on February 10, 2026. Posted in HVAC.

As 2026 approaches, many homeowners are asking the same question: What happened to the federal HVAC tax credits? If you were planning to upgrade your heating and cooling system and rely on federal incentives to offset the cost, an important change is coming. Major provisions that supported energy-efficient upgrades are set to expire at the end of 2025, reshaping how homeowners save on HVAC improvements moving forward.

Understanding how 2026 HVAC tax credits are changing, and what options replace them, can help you plan smarter, avoid surprises, and still make a cost-effective upgrade.

The End of Section 25C and 25D: What’s Changing?

Two key federal incentives were scheduled to expire on December 31, 2025:

Section 25C – Energy Efficient Home Improvement Credit
Section 25D – Residential Clean Energy Credit

Together, these programs helped homeowners save thousands on qualifying upgrades, including heat pumps, high-efficiency furnaces, and certain HVAC components.

With the Section 25C expiration, homeowners will no longer be able to claim federal tax credits for most energy-efficient HVAC installations completed in 2026 and beyond. That includes what many refer to as the federal heat pump credit 2026, which, under current rules, will no longer be available.

For homeowners who delayed upgrading or planned to wait, this change could significantly impact the overall cost of a new system.

How the Loss of Federal Credits Affects 2026 HVAC Upgrades

Without federal tax credits, the upfront cost of installing a high-efficiency HVAC system may feel steeper in 2026. However, this doesn’t mean upgrading is no longer worthwhile, or unaffordable.

In fact, newer systems continue to offer:

Lower monthly energy bills
Improved comfort and temperature consistency
Better indoor air quality
Reduced risk of breakdowns compared to aging equipment

The key difference is where the savings come from. Instead of federal tax relief, homeowners will need to lean more heavily on high-efficiency HVAC incentives offered at the local and utility level.

Utility Rebates: The New Front Line of HVAC Savings

While federal programs are sunsetting, many local utility providers are expanding or maintaining rebate programs to encourage energy efficiency. These rebates can still offer meaningful savings, sometimes hundreds or even thousands of dollars, depending on your system choice and location.

Utility rebates may apply to:

High-efficiency heat pumps
ENERGY STAR®-rated HVAC systems
Variable-speed furnaces or air handlers
Smart thermostats installed with qualifying equipment

Unlike tax credits, rebates are often applied upfront or shortly after installation, reducing your out-of-pocket cost immediately. Availability and rebate amounts vary, making it especially important to work with a contractor who understands current local programs.

Financing Options That Replace Lost Federal Savings

Another way homeowners are adapting to the end of federal incentives is through flexible financing. Rather than paying the full cost upfront, financing spreads payments over time, often with competitive interest rates or promotional terms.

At Beltway, financing options can help:

Offset the loss of federal tax credits
Make high-efficiency systems more accessible
Allow you to upgrade now instead of waiting for a breakdown
Keep monthly costs predictable

In many cases, energy savings from a new system can help balance monthly financing payments, softening the overall impact of the Section 25C expiration.

Why 2026 Is Still a Smart Time to Upgrade

Even without federal credits, upgrading your HVAC system in 2026 can be a smart move, especially if your current system is aging, inefficient, or unreliable.

Modern HVAC systems are designed to:

Use significantly less energy than older models
Meet stricter efficiency standards
Perform better in extreme temperatures
Reduce long-term repair and maintenance costs

Waiting too long can lead to emergency replacements, fewer equipment options, and higher stress, often at the worst possible time.

Plan Ahead for a Smarter 2026 HVAC Upgrade

The end of federal HVAC tax credits doesn’t mean the end of smart savings; it just means the strategy has changed. By combining utility rebates, flexible financing, and expert system selection, homeowners can still upgrade efficiently and affordably in 2026.

If you’re considering a new system or want to understand your options before incentives disappear, the team at Beltway Air Conditioning, Plumbing and Heating is here to help. Contact Beltway today to explore rebate opportunities, financing solutions, and expert guidance to make your 2026 HVAC upgrade a success, without missing a beat.

Everything Maryland Homeowners Should Know About SpacePak Maintenance & Repair

Written by Kevin on October 10, 2025. Posted in HVAC.

If you own a home in Maryland, you know how unpredictable the weather can be. Summer brings stifling heat and heavy humidity, while winters bring below-freezing temperatures. Many older homes in the area cannot accommodate traditional ductwork, which is why SpacePak systems have become so popular. These high-velocity central air systems deliver year-round comfort without requiring extensive remodeling.

Like any heating or cooling system installation, they need regular care to stay reliable and efficient.

This guide covers everything Maryland homeowners like you should know about SpacePak maintenance and repair. From understanding common issues to knowing when to call in the professionals at Beltway Air Conditioning and Heating, you’ll learn how to keep your system running at peak performance.

Why SpacePak Systems Work Well for Maryland Homes

SpacePak systems stand out because they use smaller, flexible tubing instead of bulky ductwork. That makes them ideal for older homes in Baltimore, Annapolis, and other historic towns across Maryland. Many homeowners choose them because they provide powerful, even cooling and heating, while preserving the character and architecture of these homes.

Maryland’s climate also puts HVAC systems to the test. Humid summers strain cooling systems, while cold winters demand dependable heating. A SpacePak system can meet these needs, but only if you maintain it properly. Neglect leads to reduced efficiency, higher energy bills, and costly repairs down the line.

These systems also fit the unique needs of Maryland neighborhoods where zoning laws or preservation rules may prevent major renovations. By installing a SpacePak system, you gain modern comfort without sacrificing historic charm. You must also care for the system to make sure that everything runs smoothly.

Common SpacePak Problems Maryland Homeowners Face

Understanding common issues helps you recognize when your SpacePak system needs professional attention. One frequent problem involves airflow restrictions. Because SpacePak systems rely on flexible tubing, dust and debris can build up faster than in traditional ductwork. This buildup causes weak airflow and reduces efficiency. Regular cleaning and filter changes can prevent this issue.

Another problem comes from wear and tear on the blower motor. The motor works hard to move air through the compact system. If it runs without proper lubrication or develops electrical issues, you might hear strange noises or notice uneven temperatures throughout your home.

Leaky tubing is another concern. Even though the flexible ducts used in SpacePak systems are durable, they can still develop small leaks over time. These leaks force the system to work harder to deliver the same level of comfort, driving up your utility bills.

Finally, Maryland’s damp climate can strain the system’s drainage. If moisture isn’t managed, water may collect around the unit, leading to mold growth or even structural damage in nearby areas.

Recognizing these warning signs early prevents bigger problems later. If you spot weak airflow or hear unusual noises, it may be time to schedule an inspection.

The Importance of Regular SpacePak Maintenance

Routine maintenance is important when it comes to preventing these issues. A well-maintained system lasts longer and performs better than one that is not. If you schedule annual heating and cooling tune-ups, you save money on repairs and keep your home more comfortable year-round.

During a maintenance visit, a technician from Beltway Air Conditioning and Heating will inspect the blower motor, check for leaks in the tubing, and ensure the condensate drain line works properly. We also check to make sure you have clean filters to prevent dust buildup that restricts airflow. These steps will help your system maintain peak efficiency, which is especially important in Maryland’s hot summers.

Maintenance also allows our technicians to catch small issues before they escalate. For example, a minor leak in the tubing might seem insignificant. If ignored, it can lead to uneven cooling and wasted energy. A simple repair today prevents major costs tomorrow.

When you invest in routine service, you also protect indoor air quality. The heat and moisture in Maryland can encourage mold growth. By keeping your SpacePak system clean, you minimize the chance of allergens being able to circulate in your living space.

When to Call for SpacePak Repairs

Even with regular maintenance, every HVAC system eventually needs repair. Knowing when to call us at Beltway Air Conditioning and Heating saves you from bigger headaches later. Unusual noises, like banging, grinding, or squealing, often indicate motor or blower problems. If you ignore these sounds, they can turn into expensive repairs.

Uneven temperatures can also signal a problem. If some rooms feel much warmer or cooler than others, leaky tubing or a failing blower may be the cause. You should also call for repairs if your energy bills suddenly spike. A system that runs longer or works harder than usual often wastes energy due to hidden issues.

Finally, never ignore water leaks or moisture buildup around your system. These problems can damage your home and lead to mold growth if left unaddressed. Prompt repairs keep your SpacePak system reliable and ensure your home stays comfortable during Maryland’s most extreme weather conditions.

The Cost of SpacePak Maintenance and Repair in Maryland

Don’t hesitate to schedule service because you worry about costs. In reality, maintenance and minor repairs cost far less than replacing a neglected system. The cost of maintenance varies depending on the service package you choose, but it is generally affordable compared to the savings on energy bills and future repairs.

Repair costs depend on the issue. Replacing a blower motor costs more than fixing a clogged drain line, but both repairs cost less than installing a new system. When you work with Beltway Air Conditioning and Heating, you receive upfront pricing and clear recommendations.

You also benefit from the long-term value of consistent care. By extending your system’s lifespan, you delay the cost of a full replacement and enjoy better efficiency every season. In a state like Maryland, where summers and winters both put heavy demands on HVAC systems, those savings add up quickly.

Why Maryland’s Climate Makes SpacePak Care Essential

The hot summers and cold winters in Maryland can create additional challenges for your system. High humidity increases the chance of condensation issues, while rapid temperature swings put extra strain on your equipment. SpacePak systems are able to handle these demands well when properly maintained.

Historic homes in areas like Ellicott City, Frederick, and Annapolis often rely on SpacePak because traditional ductwork isn’t an option. These homes deserve careful care to preserve both comfort and character. Regular service ensures that your SpacePak system keeps working without compromising your home’s structure or style.

Maryland also experiences intense seasonal changes. A system that performs flawlessly in the spring may struggle under the extreme demands of July or January. By scheduling service ahead of these peak seasons, you will be able to relax knowing that your system will perform reliably when you need it most.

8 Tips For Extending The Life of Your HVAC System

Written by Kevin on December 8, 2024. Posted in HVAC.

For most homeowners, the HVAC system is a major investment in the property. Although you must expect the system to eventually require replacement, you want to get as many years of service as possible. Fortunately, several things can make a notable difference in the service life of your HVAC system. Even better, many ways to help a system involve small tasks and routine maintenance. Follow these eight tips to give your HVAC a longer lease on life.

1. Regularly Change the System’s Filters

Airflow is your HVAC’s best friend. Ample airflow keeps fans from becoming strained. It also provides more oxygen, benefiting any system that uses burners for heating. Keeping dust and debris out of the system also reduces the risk of junk building up in moving parts and damaging them. With everything running better, you can also expect the system’s running times to be lower. Consequently, you can expect the system to suffer less wear and tear.

Performing a filter replacement is also an excellent opportunity to check in on your HVAC system. If you see that the filters are accumulating less or more particulate matter than expected, this may tip you off to something potentially failing. You will also get a sense of how often they need to be replaced. Depending on your household and the surrounding environment, filter replacements may be necessary once per month to every three months.

Many homeowners elect to handle air filter replacements themselves. However, you should at least have one of our technicians show you where everything is so you don’t miss any filters. Likewise, be sure to ask about the grade needed for the filter. Some systems do not support higher MERV-rated filters, and using them can strain the HVAC. Running the right filters in the HVAC is just as important as regularly replacing them.

2. Annual Professional Checkups

Even if the HVAC system in your house appears to be operating perfectly fine, an annual checkup by a professional is a good idea. We send technicians to check a wide range of HVAC features. Our technicians can look at moving parts and ensure they’re properly lubricated. We can also test relays and the thermostat to verify that all the signals are ending where they need to be. Flow-rate testing from the vents also provides early clues about potential failures. The same goes for testing how well refrigerant levels are holding up.

Visual inspection is also helpful. Looking for little issues like corrosion, burned surfaces, discoloration, and frayed wires can indicate that something bigger might be happening.

3. Keep Humidity Levels Down

Humid air is harder to heat and cool. The extra moisture in the air can strain the HVAC system. Consequently, you want to be sure that your HVAC is cooling and heating dry air. This doesn’t mean you want the house to be bone-dry, though. For comfort, you shouldn’t have the humidity level dip below 30%. At the same time, it is wise to keep the humidity below 50% for efficiency and to deter mold growth.

Depending on how well your HVAC controls humidity, you may consider adding a whole-house humidifier or dehumidifier. It may end up being both, especially in a climate like we have in Maryland. A humidifier can keep levels comfortable during dry winter months, and a dehumidifier could be necessary during steamy summer months. On the upside, you can typically retrofit humidity-controlling systems into an existing HVAC.

4. Check Vents To See if They Are Open or Closed

Keeping vents as wide open as possible reduces airflow constrictions and improves HVAC efficiency. Conversely, closing vents completely prevents inefficient airflow into unused rooms. Both cases matter.

An annual check is a good idea when it comes to keeping vents open. This makes sure the vents haven’t started closing due to gravity pulling them shut. The reverse can also happen, with gravity pulling vents open in rooms where you don’t want airflow. A quick walkthrough of your house could save you significantly by making sure all the vents are at your preferred level of openness. This is a great time to check temperature accuracy using a temperature gun on the vents to see if the temperature matches the thermostat display.

5. Seal Leaking Ductwork

Air wants to escape your home’s HVAC system and will do so at the first available outlet. If the ductwork in your house is leaky, the air could escape to undesired locations. Mainly, you want to be sure there isn’t leakage in the basement or the attic. Air that escapes is the air that needs to be heated and cooled longer to achieve the same results. For example, your house might lose 10% of its air to HVAC leaks. That forces the HVAC system to run longer to compensate for lost efficiency. This ultimately shortens the system’s service life through additional wear and tear.

6. Protect Outdoor HVAC Components

The air conditioning components in your HVAC system tend to have significant outdoor exposure. Condenser coils are the main potential problem. Even something as simple as having a tree near the outdoor unit can lead to junk collecting in the coils. Cleaning helps, but the best solution is not to have anything near the system. Cutting down a nearby tree or bush can protect the coils from debris buildup.

You should also protect outdoor components from other risks. Many people have small fences around the components to prevent objects or people from accidentally getting near them.

7. Consider a Programmable Thermostat

Better temperature control leads to better efficiency. By extension, more efficient operation leads to less wear and tear. A programmable thermostat is the best way to accomplish better control.

Programmability also helps by reducing unnecessary run times. Suppose no one is home during a typical weekday. Why let heating or cooling equipment run more than is necessary? Programming the thermostat to tolerate lower temperatures on cold days and higher ones on hot days will lead to fewer cycles. Over the system’s lifetime, this can save the equivalent of months or even years of use.

A bonus is that you can program the system to bring the temperature back to an average level before you get home. Ideally, you won’t even know that the system is running less until you see the reduction in your home’s energy bills.

8. Handle Problems Promptly

No one likes the cost of an HVAC repair job. However, letting failing components remain as is to save money now will cost you down the road. If you notice a problem like short cycling, an unusual smell, or uneven heat and cooling, tell us about it.

HB Home Services and Air Solutions: A Transition to Beltway Heating, Air, and Plumbing

Written by Kevin on November 26, 2024. Posted in HVAC.

HB Home Services and Air Solutions have long been trusted names in Maryland’s home service industry. However, after years of dedicated service, they faced challenges that led to their closure—a reflection of the difficulties of operating a home service business in Maryland. With high competition, a short HVAC season due to mild springs and mild temperature falls, and increasing private equity acquisitions of smaller companies, the market is as demanding as it is dynamic.

Understanding the need to ensure their loyal customers were cared for, HB Home Services sought a partner who truly valued customer satisfaction and long-term relationships. This search led them to Ryan Grimes and the team at Beltway Heating, Air, and Plumbing.

Why Beltway?

HB’s decision wasn’t made lightly. Their former Director of Operations emphasized that Beltway was the ideal company to carry on their legacy. But the endorsement didn’t stop there. HB consulted Lennox, their preferred HVAC equipment provider known for its quality, to identify the best company in Maryland. Lennox’s District Manager Martin, with deep insights into the operations of all HVAC and plumbing businesses statewide, recommended Ryan Grimes and Beltway Heating, Air, and Plumbing as the top choice.

At Beltway, we’ve built our reputation not on flashy ads but on consistently delivering quality work. We don’t do a ton of advertising, so if you’ve never heard of us, we get it.

What matters most: people. We’re proud to be known as a trusted, certified provider for Maryland homes.

The Beltway Difference

While there are a few differences between HB Home Services and Beltway, our shared values of quality and customer care remain central. Here’s what sets us apart:

Affordable Service Plans: At $175 per year, our service plan includes two HVAC maintenance visits, one plumbing visit, and a complimentary water test.
Filters: Instead of carrying filters on service calls, we’ve chosen to focus on providing efficient and thorough maintenance. With the vast variety of filter sizes available today, it’s a logistical challenge to stock and transport every type, which could take time away from delivering the best service possible. Instead, we offer a convenient and cost-effective option: a two-year supply of filters delivered directly to your door at cost. This allows you to always have the right filters on hand, and when you combine this with our service plan pricing, it’s still more affordable than HB’s previous offerings.
Service Area: Our service area remains largely the same as HB Home Services, covering most of Maryland. The only exception is that we do not service certain parts of Baltimore City. Otherwise, you can expect the same coverage and reliable service for your home’s needs.
Experienced Leadership: Gary North, formerly of Air Solutions/HB and now our Operations Manager, brings 40 years of industry experience to Beltway. He describes Beltway as the best company he’s ever been part of, with unmatched confidence in our team’s ability to serve you. Gary can be contacted directly at Gary@BeltwayHVAC.com for any questions, concerns or assistance.

12 Reasons It’s Worth it to Invest in a High-Efficiency HVAC System

Written by Kevin on October 11, 2024. Posted in HVAC.

If the time has come to replace your home’s old HVAC system, there is a wide range of options. In fact, there are more options now than a decade or more ago when you purchased your current system. That includes modulating furnaces, dual-fuel heat pumps, and high-SEER air conditioners. These high-efficiency systems do cost more up front but provide many benefits. Let’s explore those to see why the added investment may be the right choice for your home.

1. Suitable for All Homes

There are no special requirements to upgrade to a high-efficiency system. If you have a traditional furnace, you can upgrade to a high-efficiency furnace with little to no modifications. You may need condensate drainage for a condensing furnace, for instance. That said, if you already have a drip pan for the AC, we can often use it. If you currently have a furnace and AC pairing, upgrading to hybrid heating is simple. Upgrading to a modulating blower is simple too, and if your home lacks ducts, there are ductless solutions. Those include mini-splits and variable refrigerant flow (VRF) systems.

2. Enhanced Comfort

High-efficiency systems foster a more comfortable home and more consistent comfort. Temperature readings and control are much more precise. These often allow for relative humidity (RH) adjustment and “feels like” temperature settings. High-efficiency systems provide greater airflow and give you finer and more robust control over it. The industry has also come a long way in manufacturing efficient, high-output systems. Modern high-output HVAC systems are much better suited to larger homes, including those with multiple levels.

3. Improved Indoor Air Quality

Modern high-efficiency systems generally run cleaner. This is particularly notable with fuel-burning systems, such as gas and oil furnaces. High-efficiency HVAC units don’t have to cycle as long and minimize the impact to air quality. They also allow for high-efficiency air filters. Most systems support a minimum efficiency reporting value of at least 13. At that level, filters trap a minimum of 90% of household allergens. Some systems allow up to 16, which is the highest rating on the MERV scale. There are even systems that support high-efficiency particulate air (HEPA) filters, which filter at least 99.97% of all particulates.

4. Reduced Operating Costs

The Department of Energy (DOE) estimates that the average home can reduce its annual HVAC costs by at least 30%. Doing so requires proper insulation and sealing of your home and a programmable or smart thermostat. You must also upgrade to an HVAC system that meets DOE standards, which are lower than Environmental Protection Agency (EPA) standards. High-efficiency equipment can increase that savings to 50% or more.

5. Lessened Household Carbon Footprint

The DOE estimates that 40% of the country’s carbon dioxide (CO2) emissions come from heating, cooling, and hot water. AC alone accounts for 15% of the world’s energy consumption and will likely reach 25% by 2050. A high-efficiency system will reduce your household’s environmental output by at least 20% and as much as 50%.

6. Longer Lifespan

High-efficiency HVAC equipment will typically have a longer lifespan. It’s not unusual for these systems to last 25 years or even longer. One reason is that they don’t cycle as often and are subject to less wear and tear. Another reason is that component quality and sophistication are generally higher as well. Warranties also reflect these expected longer lifespans.

7. Lower Total Cost of Ownership

While high-efficiency systems cost more initially, they usually cost less over the life of the equipment. There is a range of factors to this. Some we’ve already discussed, such as lower operating costs and extended lifespan. There are others, such as rebates and tax credits, which we’ll discuss next.

8. Rebates and Tax Credits

Whether a high-efficiency HVAC system is worth it comes down to whether the long-term savings outweigh the added initial cost. Energy incentives help to offset that added cost and make the investment more appealing. Rebates are available through manufacturers, utility companies, federal, state, and local governments, and other groups. You can claim multiple rebates if they’re available, and there are few requirements other than the model you select. Typically, you do need to buy a unit with the ENERGY STAR label. It’s a certification awarded by the EPA for appliances among the most efficient in their class.

Choosing an ENERGY STAR heating, cooling, or ventilation system or accessory may also make you eligible for a federal tax credit. The Energy Efficient Home Improvement Credit has existed in one form or another for decades. It lets you claim an annual nonrefundable tax credit up to $3,200. The High-Efficiency Electric Home Rebate provides you either a $4,000 or $8,000 reimbursement for a heat pump depending on household income.

9. Safer Operation

It’s important to note that all modern HVAC systems are incredibly safe, including hot water and steam boilers. Still, high-efficiency fuel-burning furnaces and boilers are even safer than their standard counterparts. One reason is that they have sealed combustion chambers. That upgrade makes it even less likely that carbon monoxide (CO) will mix with your air supply.

10. Quieter Operation

High-efficiency HVAC systems are generally quieter for several reasons. They don’t have to cycle as often. When they do cycle, they don’t have to run at full bore. They can throttle down as needed. Noise-reducing blower fan blades are common as well.

11. Future-Proofing

Upgrading your home now will prepare you for a future inevitability. Consider that the DOE has already updated annual fuel utilization efficiency (AFUE) requirements for the future. By 2029, you won’t be able to buy a furnace with an AFUE rating of less than 95. That means you’ll need a modulating blower and condensate drainage system for your furnace.

12. Increased Property Value and Home Appeal

Another way high-efficiency HVAC systems provide an excellent return on investment is by increasing your property value. If you may sell or rent your home in the future, these upgrades will make it more appealing and move faster.

Other Considerations

High-efficiency systems open up a broad range of additional options. Manufacturers often use green refrigerants with their high-efficiency air conditioners, heat pumps, mini-splits, and VRF systems. Higher efficiency systems are a better option for HVAC zoning. Zoning is where we organize your home into discrete zones that you can adjust independently. You can use a programmable or smart thermostat with any HVAC system, but high-efficiency systems often have integrated smart features. That includes predictive analysis for lower maintenance and repair costs. High-efficiency systems often have integrated humidity control or at least provide better support for HVAC add-ons like humidifiers and dehumidifiers.

The Hidden Dangers of a Leaky HVAC System

Written by Kevin on October 4, 2024. Posted in HVAC.

When you hear the word “leak,” you probably start to panic. Whether you’re dealing with a plumbing leak or a leak in your Hanover, MD home’s HVAC system, these are household problems that can lead to expensive issues. There are several locations and ways that your HVAC system can leak, including a leak of refrigerant or leaky ductwork. Let’s look at the hidden dangers associated with these leaks and the ways that you can address the problem.

HVAC Condensate Drain Leaks

There is a certain amount of condensation coming from your HVAC system as part of its normal operation. However, this condensation must be able to move away from your HVAC equipment and home. A condensate drain line allows for this process, but clogs and leaks can occur. This is usually a minor repair job if you spot the problem early on. A sign of this issue is pooling water around your heating or cooling equipment.

Leaks in Your Ductwork

The ductwork system in your home is designed to distribute conditioned air to your various living spaces. Holes, gaps, and cracks can occur in your ductwork, leading to air leaks. This can cause a big loss of efficiency. It can also impact your indoor air quality by introducing particulate matter into your circulated air.

Refrigerant Leaks

Refrigerant is a material that allows for a heat exchange to occur when you are running your air conditioning equipment. The design of your HVAC system typically keeps refrigerant in a sealed system, but leaks can occur because of damage or routine wear and tear. It’s dangerous to expose yourself to refrigerant. Low refrigerant levels can also cause your HVAC system to run more frequently to keep your home at a comfortable temperature. Refrigerant levels can be checked as part of annual routine maintenance.

What to Look For

There are some subtle, and not so subtle, signs that you can watch for that indicate there are leaks in your HVAC system.

Pooling Water or Dripping

It’s normal for a little bit of condensation to form around your air conditioning unit, especially if it’s located outdoors. However, pooling water or water stains around your furnace or other areas of your HVAC system is not normal. You may see an increase in the amount of water that is pooling if your system has been running more frequently than normal, as would be the case with extreme temperatures.

A Decrease in Efficiency of Your Equipment

If you have leaking refrigerant or leaking air, this can cause your HVAC system to run more frequently. This decreases the efficiency of your unit and can increase your utility bills. Keep an eye on your energy usage, which can indicate HVAC issues if there’s no other known cause for the increase.

Odd Sounds

Do you hear a rattling sound when your HVAC system is on? What about grinding, gurgling, or rattling? Odd sounds can indicate that you have leaks in your HVAC system.

Bad Smells

Gaps and cracks in your ductwork can introduce moisture into your system. This can quickly lead to mold growth. When mold spores circulate around your home, this can cause a musty odor. Not only is this smell unpleasant, but it’s dangerous to your health and wellbeing.

Hot or Cold Spots

Do certain rooms or areas of your home feel hotter or colder than others? These uneven spots can point to several HVAC issues, including ductwork leaks, refrigerant leaks, thermostat problems, and more.

HVAC Leak Dangers and Concerns

We touched on the dangers of mold growth in the home, which can lead to an increase in allergies, asthma attacks, and respiratory issues. There are other dangers that you should be aware of.

HVAC Equipment Damage

If you have HVAC leaks in your equipment or ductwork system, this can cause damage. This damage can lead to costly repairs. In some cases, this can shorten the lifespan of your HVAC system. Ductwork usually lasts for about 10 to 15 years. Furnaces and air conditioning devices last anywhere from 15 to 20 years. Eventually, our team may advise that you will need to replace your equipment or ductwork because repairs to them are becoming more frequent because of cumulative leak damage.

Household Damage

You may also see damage occur to areas of the home like your flooring, walls, ceilings, etc. when HVAC leaks are present. This can be expensive and inconvenient to repair.

Dangers to the Environment

Certain HVAC leaks can be dangerous to the environment. For example, refrigerant that escapes your closed system can release harmful gas into the air. Whenever work needs to be done to your air conditioning system that requires us to work on the refrigerant, there is specific protocol we must follow to prevent leaks.

Preventing HVAC System Leaks

While repairs can be made to fix the leaks in your HVAC system, routine maintenance and annual inspections can spot problems early on. This allows for minor repairs to be made before the issues get out of hand and become much more expensive. Maintenance can also prevent these leaks from occurring in the first place, keeping your energy bills low and helping you save money.

Other things you can do to minimize the risk of leaks in your HVAC system include having your ductwork sealed. Various products are available that will close any gaps, cracks, or holes that are in your system before they become larger. This is a relatively simple procedure that we can perform in one day.

Having our team monitor your furnace and air conditioner can help us spot problems with your drain lines, filter, coolant, etc. We can clean out your condensate line if it has a buildup of mineral deposits or sediment.

There are various seals that close your furnace, air conditioner, and ductwork. These seals can break down over time, causing leaks. Routine maintenance includes replacing these seals as needed.

It’s common for the bends and connections of your ductwork to break down over time. You can look for cracking, peeling, or other signs of damage that indicate the material is compromised and needs to be replaced. If you’ve recently had any remodeling work done in your home or you were moving items around the area of your furnace or ductwork, you may have inadvertently crushed areas of the ducts. Repairs or replacements should be completed before leaks cause problems.

Understanding Different Air Duct Materials

Written by Kevin on September 19, 2024. Posted in HVAC.

If you want an efficient and high-performing central HVAC system in your Hanover, MD home, you need efficient and high-performing ductwork to support it. HVAC air ducts are the distribution channels that deliver conditioned air to every room. With the right duct materials, you can minimize heat loss and heat gain during air delivery, protect your indoor air quality (IAQ), and limit HVAC noise. Read on to explore the different options in air duct materials and the benefits and drawbacks of each.

Sheet Metal Air Ducts Are the Most Popular Choice

Hands down, sheet metal air ducts are the most popular choice in the nation. They allow for a customized approach to ducting. Sheet metal workers can streamline these features to suit the needs and nuances of individual houses and HVAC equipment types. Some sheet metal materials are lightweight and flexible enough to bend around sharp corners. Flexible sheet metals can also be custom-fitted to suit tight spaces.

Research performed by the University of Florida found that HVAC air ducts can be responsible for the loss of up to 40% of an HVAC system’s heating and cooling energy. Fortunately, with tight fittings and professional duct sealing and insulation, sheet metal air ducts can experience minimal heat gains and heat losses. However, they aren’t without their drawbacks.

All sheet metal air ducts expand and contract when subjected to dramatic temperature and pressure changes. These movements often produce loud popping or banging sounds. If you want whisper-quiet HVAC operation, you might not get it with sheet metal ducting. Proper installation and quality insulation both have sound-dampening benefits, but movement-related sound invariably increases as sheet metal ducts near the end of their lifespans.

Stainless Steel Air Ducts

Stainless steel air ducts are chemical- and corrosion-resistant. They’re strong, highly rigid, and easy to maintain. They work well in hostile environments and in spaces where moving large volumes of air is required. Although stainless steel air ducts are an increasingly common choice for new homes, they’re most often used in commercial construction.

Stainless steel air ducts are the most expensive sheet metal duct type. Their high levels of rigidity also make them unsuitable for tight spaces, sharp corners, and sharply sloped ceiling areas. This is especially true when installing, modifying, or extending HVAC air ducts post-construction.

Galvanized Steel

Galvanized steel is the most durable and longest-lasting option for sheet metal ducting. It’s also significantly cheaper than stainless steel and a bit easier to adapt to tight, cornered, or otherwise awkward spaces. The smooth interiors of galvanized steel ducts are resistant to mold, mildew, and other fungal growths. They also allow for smooth, unimpeded airflow.

Among the many benefits of galvanized steel is its impressive fire rating. Galvanized steel has an A1 fire rating. Thus, these ducts can play an important role in slowing the spread of fires from room to room.

Unfortunately, galvanized steel is prone to rust and other corrosion. If you have consistently high humidity in your home, galvanized steel ducting could have a relatively short lifespan. To keep galvanized steel ducts in optimum condition, homeowners must:

Schedule annual HVAC service for all heating and cooling equipment
Perform regular air filter changes
Keep the perimeters of their outdoor condenser units clear
Regularly remove built-up debris from HVAC air vents

These and other ongoing maintenance tasks ensure good airflow and limit significant rises in humidity. Although they’re important for all HVAC systems, they’re critical for preserving galvanized steel ducting.

Aluminum Ducting

Though much less durable than galvanized and stainless steel, aluminum air ducts are valued for being both lightweight and flexible enough for easy installation in tight corners and small spaces. Aluminum ducts are also significantly cheaper than both steel types, and they offer good thermal conductivity. With professional duct sealing and insulation services, homeowners can limit their costs for HVAC air duct replacement and still enjoy high levels of HVAC efficiency.

Like galvanized steel, aluminum is prone to corrosion when installed in humid environments. Moreover, although it’s cheaper than galvanized and stainless steel, it’s more costly than fabric, plastic, and other non-metal ductwork materials. Due to its high malleability, aluminum ducting also requires special tools for installation, especially when this material is used for longer runs of ducting.

Mild Steel Air Ducts

Mild steel (MS) air ducts are often referred to as galvanized mild steel ducts. Like galvanized and aluminum ducts, they have low levels of corrosion resistance and aren’t suitable for humid environments. However, the high rigidity of MS air ducts allows for limited air resistance and promotes even and consistent air distribution.

This metal is incredibly ductile when heated. This makes it perfect for shaping, cutting, and otherwise altering to suit awkward or tight spaces. When used in residential HVAC systems, it’s typically for aesthetic purposes, such as when post-construction air duct installation results in exposed duct sections in visible areas. MS ducting also works well in non-load-bearing walls and other interior frameworks.

Flexible Air Ducts

Often referred to as flex ductwork, flexible air ducts are made from flexible metal, durable plastic, reinforced fabric, or fiberglass. These air ducts are easy to install, low in cost, and flexible enough to suit a broad range of applications. They work exceedingly well in tight spaces and corners. They’re also virtually soundless. Flex ducts are an excellent choice for affordable and all-around quiet HVAC installations. However, flex ducts have shorter lifespans than most rigid ducting. They’re also more difficult to clean.

Fabric Air Ducts

Also known as textile air ducts and air socks, fabric air ducts are porous, lightweight sleeves installed instead of metal or fiberglass ducting. Textile ducts are customizable, easy to install, and significantly less expensive than sheet metal. They also allow for even air distribution by preventing radical changes in static pressure. Given that fabric doesn’t expand or contract when exposed to temperature extremes, it’s also among the quietest ductwork materials currently available.

The drawbacks of fabric air ducts make them unsuitable for some homes and building areas. For instance, they’re less durable than most HVAC air duct types. They’re also more easily entered by pests and damaged by moisture, UV rays, and other exposure.

Fiberglass Air Ducts

Fiberglass air ducts have a lightweight sheet metal construction and a thick interior lining of fiberglass. This offers superior insulation and sound-dampening. Fiberglass air ducts work well in highly corrosive environments due to their excellent corrosion resistance. They’re also mold-resistant. As an inorganic material, fiberglass is less susceptible to mold problems, although not entirely invulnerable.

When the fiberglass lining in these ducts gets wet or contaminated with mold or other fungi, the U.S. Environmental Protection Agency (EPA) recommends replacing all affected materials. The intensive cleaning that wet or moldy fiberglass ducts require can shorten their lifespans. It can also dislodge micro-fine particles of glass that enter HVAC systems.

PVC Air Ducts

For high-humidity and corrosion-prone environments, PVC air ducts are an excellent choice. PVC has impressive insulating properties and high levels of moisture resistance. Though not as affordable as flex ducting, it’s less expensive than all sheet metal types. The primary drawback of PVC ducting is its limited heat resistance. Thus, you can’t use PVC if you have a gas-fired furnace for winter heating. However, it does work well with the lower operating temperatures and radiant heating supplied by heat pumps.

Pros and Cons of Ductless Mini-Splits

Written by Kevin on September 5, 2024. Posted in HVAC.

One type of HVAC system that’s gained a lot of popularity over the past 20 years is the ductless mini-split unit. This type of system allows you to enjoy all year-round comfort without the need for any traditional ductwork. If you’re in the market for a new HVAC system, it can be helpful to understand both the benefits and drawbacks of this type of system.

Heating and Cooling

Probably one of the most significant benefits of a ductless mini-split system is that it offers both heating and cooling capabilities. You no longer have to invest in two different types of HVAC systems to keep your family comfortable throughout the year. Now, you can purchase one system to handle all your comfort needs.

No Ductwork Needed

One of the biggest problems with older homes is that they don’t always have ductwork. It can be extremely expensive to have ductwork put in your home after it is finished. This is because flooring and walls will need to be removed in order to gain access to the appropriate areas to install your new ductwork. When you opt for a ductless mini-split system, you won’t need to worry about any of that invasive installation.

All these systems require is a small hole on the exterior wall of each room that gets a mini-split unit. This makes them the perfect heating and cooling solution for home additions where you can’t connect onto existing ductwork.

Energy-Efficient Operation

Ductless mini-split systems offer energy-efficient operation. In the summertime, they tend to operate more efficiently than traditional central air conditioning systems. This is mainly because they don’t lose any of their cold air through gaps in ductwork since they don’t use it.

In the wintertime, these units can be extremely energy-efficient when they operate in mild climates. Unlike traditional heating systems, the ductless mini-split unit does not create heat. It simply transports heat from one location to another. This can allow it to reach efficiency levels of up to 300 to 400%.

Federal Tax Rebates

Because ductless mini-split systems are so energy efficient, they qualify for a federal tax incentive. Under the Inflation Reduction Act, homeowners can receive 30% of the total cost of their mini-split system back in the form of a tax rebate. They can claim amounts up to $2,000. Even some local municipalities and state governments are offering their own tax incentives for homeowners who invest in these energy-efficient products.

Zone Temperature Control

If you have a mini-split system installed in your home, you will have individual units in each main room. Each unit will come with its own remote that will allow you to set individual temperature settings. This gives you the ability to enjoy zone temperature control throughout your entire home.

Instead of relying on just one thermostat for your entire home, you can enjoy setting a specific temperature for each room. This not only will go a long way in enhancing your overall comfort, but it can provide other benefits as well. You can enjoy fixing hot and cold spots throughout the year. This also gives you the capability to be more efficient with your energy usage.

Quiet Operation

One of the more annoying parts of forced air heating systems is the movement of air through your ductwork can be quite loud. When you get a ductless mini-split system, you don’t have to worry about the noise. These units operate at a noise level similar to a whisper.

Better Quality Air

Another area where ductless mini-split units outperform traditional forced-air HVAC systems is when it comes to air quality. Systems that rely on ductwork tend to experience more buildup of airborne debris that can reduce the quality of air inside your home. On the other hand, ductless models don’t have to deal with that excess buildup. Rather, each unit has its own filter that removes contaminants from the air as air circulates through the unit. This leads to better overall indoor air quality than with a traditional forced air heating or cooling system.

Dry Mode for Humidity Control

One feature that many new ductless mini-split units come with is dry mode. This works to remove excess humidity from the air without exerting the normal amount of energy to cool your air. It does this by pulling air over the evaporator coils at a much slower operating speed. By removing excess humidity without running your system at full speed, this system can allow you to be more comfortable in your home. Traditional central air conditioning systems must be running in cool mode to offer any sort of humidity control.

Not Efficient in Cold Climates

One major drawback of ductless mini-split units is that they don’t function efficiently at below-freezing temperatures. When temperatures get too cold, they’re unable to extract heat from the air outside. Instead, these units switch to their auxiliary heating mode, which works very similarly to a heating element inside an electric furnace.

Unfortunately, when in auxiliary heating mode, these units are going to be quite expensive to operate. One alternative that a lot of people use in colder climates is a backup heating system. This system will allow you to enjoy all the energy efficiency that comes with your ductless mini-split system when temperatures are above freezing. However, when temperatures dip down below freezing, you can switch to using your backup furnace to enjoy more affordable operating costs than if you were to rely solely on auxiliary mode.

Wall Units Can Be Ugly

Traditionally, ductless mini-split units were only available in wall-mounted models. These are a decent size box that is about one to two feet long by around eight inches high. Unfortunately, they’re not the nicest thing to look at as they stick out from your walls. This can be a big drawback for some people. It’s important to note that modern-day mini-split units are also available with floor-mounted and ceiling-mounted units, with the latter being the more discreet of the two.

More Maintenance

Another drawback of mini-split systems is they do require a little bit more maintenance than your traditional forced-air heating and cooling systems. The main difference in maintenance has to do with the filter. Each mini-split unit will have its own built-in washable filter. This will need to be washed every few weeks to ensure optimal efficiency. With traditional HVAC systems, you only need to change out one filter every two to three months.

Bigger Rooms May Need Multiple Units

Another known disadvantage of mini-split units is they can only handle so much square footage per unit. Your HVAC technician will have to determine the square footage of each room and pick a unit that matches that. Unfortunately, there may not be units big enough to cover the entire square footage of your bigger rooms. In this case, you may have to purchase more than one unit to handle your larger rooms.

13 Factors That Affect HVAC Efficiency

Written by Kevin on August 20, 2024. Posted in HVAC.

HVAC efficiency refers to how efficiently your system converts energy into the cooling, heating, and ventilation you require. The more efficient your system is, the cheaper it is to run. There’s also the matter of environmental impact. HVAC is the number one contributor to the average American household’s carbon footprint. Let’s explore 13 factors that shape your system’s efficiency.

1. Efficiency Ratings

There are three core energy efficiency ratings that the Department of Energy (DOE) uses to set standards for the American consumer. In all cases, the higher the number, the more efficient the system.

Annual fuel utilization efficiency (AFUE) indicates how much fuel a furnace or boiler wastes in the conversion process. An AFUE 81 furnace wastes 19% of the fuel it converts into heat energy.

Seasonal energy efficiency ratio (SEER) measures cooling efficiency over an entire cooling season. You can use SEER not only to compare air conditioners but also heat pumps in cooling mode.

Heating seasonal performance (HSPF) is like SEER but measures heating efficiency. This is necessary for heat pumps, which transfer heat energy rather than generating heat as a furnace does.

2. Climate

In general, extreme temperatures will negatively impact HVAC efficiency. This is why the DOE sets the minimums for energy efficiency by region rather than nationwide. It’s also why northern homeowners have been slower to adopt air-source heat pumps, which run less efficiently in very cold temperatures.

3. Building Envelope

The building envelope of your home refers to its seal. A home with a tight seal will be very efficient. Homes with loose seals will waste more heating and air conditioning. Aspects that make up a building envelope include the roof, doors, windows, insulation, foundation, and so forth. One way to assess your building envelope is to schedule a home energy audit. You can then use this information to target the aspects of your home that are undermining HVAC efficiency.

4. Sizing

Size in the HVAC world refers to the overall capacity of the system. You neither want an undersized nor oversized HVAC system. The goal is to get it just right. An incorrectly sized system will cycle too frequently or for too long a period. That will drive up your operating costs. It will also increase wear and tear, which will make repairs more common and decrease the equipment life span. This is one reason why it is so important to hire a professional installer who will perform a load calculation for your home.

5. Thermostat

A thermostat is integral to efficiency because it reads the temperature in the home and dictates the heating and cooling cycles. It’s important to have a thermostat that’s centrally located and that has an accurate temperature sensor.

Programmable and smart thermostats can make your system even more efficient. Both types allow for scheduling that lets you save while you’re sleeping or away from home. Smart models add energy-saving features like energy monitoring, geofencing, and smart setback.

6. Humidity Control

Relative humidity (RH) reflects the amount of water vapor in the air within the context of temperature. In high humidity, your AC will be less efficient, and you’ll need a lower temperature to feel comfortable. You can improve cooling efficiency with a dehumidifier that lowers RH during summer. You can also improve heating efficiency with a humidifier that raises RH during winter.

7. Installation

Proper sizing is just one aspect of HVAC efficiency and why it’s so important to hire an experienced HVAC installer. Others include equipment placement, static air pressure, and adhering to the manufacturer’s specifications for the installation.

8. Maintenance

HVAC warranties typically require seasonal maintenance as a condition for coverage. Schedule in spring for your cooling system. Schedule again in fall for your heating system. This is good advice even if you have a heat pump that both cools and heats. Equipment gets dirty over time and becomes less efficient. It’s also necessary to tighten electrical connections, lubricate moving parts, and so on.

9. Static Air Pressure

Static air pressure is an important concept in HVAC performance. It refers to the resistance to airflow in the ducts. The blower is on the other end of the system moving the air. If air pressure is too high or too low, it will affect comfort throughout the entire home. It will also make the system work harder, which will decrease energy efficiency and increase your operating and long-term costs.

The main cause of static air pressure issues is a clogged HVAC filter. This is why you should check your filter at least every month and replace it as needed. During a seasonal tune-up, your technician will service your blower or air handler and check the static air pressure.

10. System Age

HVAC systems become less efficient with age. Routine maintenance and preventative repairs will slow the decline, but some deterioration is inevitable. There’s also the fact that new models are becoming more efficient each year. This is why it’s rarely economical to wait for an HVAC system to fail before replacing it. In fact, the DOE estimates that homes with older systems can save 20% or more annually with an upgrade.

11. Air Leakage

Air leakage refers to heating and cooling that seeps out of the seals in your ducts. The DOE estimates that air leakage causes heating and cooling losses of between 20% and 40%. To avoid this, schedule a yearly video camera inspection of your ducts. When the seals wear out, you can have the ducts resealed, which can lower your losses to 5% or less.

12. Zoning

Traditional central HVAC systems have a single zone, which is the entire home. A multi-zone system is a modern option through which we organize the home into multiple discrete zones. This requires additional equipment, such as a variable-speed blower and active duct dampers. Zoning makes an HVAC system more efficient because it allows you to adjust the temperature in each zone. You can, for instance, increase the AC in the zones you’re using and turn it down in those you’re not.

13. Air Balancing

In a balanced HVAC system, each vent or vent group is providing the right airflow for that particular room or area. With a traditional single-zone system, you generally only need air balancing performed during an installation or replacement. Zoned systems are more complex and sensitive. Experts recommend balancing every several years or so. An imbalanced zoned system will be less comfortable and cost more.

Understanding The Different Parts of Your HVAC System

Written by Kevin on August 6, 2024. Posted in HVAC.

Even though you rely heavily on your HVAC system to keep you comfortable throughout the year, you might not know all that much about how it works. That’s not unusual. Most homeowners’ knowledge of HVAC systems doesn’t go much beyond operating a thermostat. However, if a component of your Hanover, MD home’s HVAC fails, a bit more knowledge can go a long way toward getting you back on track. To help, here is a guide to the major components of your home’s HVAC system. We’ll identify each component and let you know exactly what it does. That way, you can approach future necessary HVAC repairs with confidence that you know what you’re talking about.

Thermostat

We’ll begin with the part of your HVAC that you’re most familiar with. Your thermostat is the device that keeps track of the temperature in your home. It also signals your HVAC system to turn on and off based on your comfort preferences. Your thermostat connects to your HVAC system via control wires. A basic thermostat will have at least four wires connecting it to your HVAC. More advanced thermostats, including smart thermostats, can have up to six wires.

You can think of your thermostat as the brain of your HVAC. The more advanced your thermostat, the more you can do with your HVAC system. Basic thermostats have little more than simple temperature sensing and on/off capabilities. Programmable thermostats make it possible to set automated temperature schedules by the day or hour. Smart thermostats feature advanced connectivity and learning capabilities to maximize HVAC efficiency and improve your comfort.

HVAC Indoor Unit

The parts contained inside your HVAC’s indoor unit vary depending on the type of system you have. For these purposes, we’ll assume you have a combination of a gas furnace and a central AC system. These are the parts you’ll find in the indoor unit of such a system.

Control Board

The control board inside your HVAC indoor unit receives signals from your thermostat and activates components as necessary. If you request heat, it will activate your furnace’s burners and blower motor to provide it. If you need cooling, your outdoor condenser unit and indoor unit blower motor will activate.

Blower Motor

The blower motor in your HVAC indoor unit draws in air through your home’s return air ducts. It pushes that air past the system’s heat exchanger or evaporator coil to heat or cool it as needed. Then, it pushes the conditioned air back through your home’s supply vents.

Combustion Chamber and Burners

The combustion chambers and burners inside your HVAC indoor unit are the main components of your furnace. Inside the combustion chamber, there’s a valve that controls the flow of natural gas into the burners. It ensures that there’s a proper mixture of gas and oxygen to support complete combustion inside the chamber. To ignite the combustion process, the burners typically rely either on a pilot light or a glow stick. The pilot light continuously burns a tiny amount of natural gas to serve as an ignition point. A glow stick uses electrical resistance to create enough heat to cause combustion of the gas and air mixture.

Heat Exchanger

Your heat exchanger is the part of your furnace that warms the air coming from the blower motor. It is like a radiator. The hot gasses resulting from the combustion process pass through sealed tubes within the heat exchanger. Those tubes have large sets of fins attached to them, which transmit the heat into the passing air. Then, the combustion gasses leave the heat exchanger to exit your home through the furnace’s flue.

Flue

Your furnace’s flue is a pipe that allows the furnace’s combustion gasses to leave your home safely. These gasses include substances like carbon monoxide, so proper ventilation is critical. Those combustion gasses also leave the heat exchanger at a high temperature. Furnace flues are typically made of aluminum, which can handle high heat without warping or suffering damage.

Evaporator Coil

When you’re running your HVAC in cooling mode, all the previously mentioned furnace parts stand idle. The only shared component that doesn’t is the blower motor, which runs in heating and cooling mode. However, in cooling mode, another type of heat exchanger called an evaporator coil goes to work. The evaporator coil receives cold refrigerant from your HVAC’s outdoor unit. As air passes over the coil, the cold refrigerant absorbs heat from the air to cool down your home. That causes the refrigerant to warm up and boil off into a gas before it leaves to return to the outdoor unit. The process of cooling the air also allows your evaporator to dehumidify the air through condensation. The collected water then drains from your indoor unit via a condensate drain line.

HVAC Outdoor Unit

Your HVAC outdoor unit is only active when you’re running your system in cooling mode. As a result, it has fewer parts than the indoor unit. Here’s what they are.

Compressor

As its name suggests, the compressor in your HVAC outdoor unit manipulates the pressure on the system’s refrigerant. Specifically, it increases the pressure on the warm gaseous refrigerant coming from the system’s evaporator coil. This raises the temperature of the refrigerant until it’s hotter than the outside air. That’s how your HVAC system can exhaust heat from your home even when it’s hot outside.

Condenser Coil

The majority of the space in your HVAC outdoor unit is occupied by a heat exchanger called a condenser coil. It’s where the hot, high-pressure refrigerant goes to release its heat into the outside air. To facilitate that, the condenser coil has a series of large fins to maximize contact with the outside air. The condenser coil gets its name from the process that happens inside it. As the hot gaseous refrigerant releases its heat, it condenses back into a liquid to begin the cooling process again.

Condenser Fan

A large fan called a condenser fan is typically situated at the top of your outdoor HVAC unit. Its job is to pull outdoor air through the fins of the condenser coil to cool the refrigerant inside it. The fan vents air straight up from the top of the unit.

Expansion Valve

After the cooled refrigerant condenses back into a liquid, it’s still too hot to help cool your home. That’s where your outdoor HVAC unit’s expansion valve comes into play. It reduces the pressure on the warm liquid refrigerant. This lowers the refrigerant’s temperature and its boiling point. At that point, it can travel back to your indoor unit to begin the cooling process again.
