Your furnace blowing cold air is certainly a frustrating problem to have. Clearly, that’s not what that sucker is supposed to do!

However, before you pick up the phone to call GAC for furnace repair, we have a few steps for you to follow to make sure this is a matter for the pros:

When Your Furnace Blows Cold Air…

Step 1: Do nothing. And by that, we mean wait about a minute to see if the air heats up. Your furnace’s heating cycle begins when your thermostat detects that the temperature in your room has dropped below the temperature set on your thermostat. Once the heating cycle begins, it can take a few seconds for the warm air from your furnace to reach your vents, so it might blow out the cold air from your ductwork in the meantime.

Step 2: Check your thermostat. There are a few things you should check for. First, make sure it’s set to “heat” and above room temperature. Next, you’re going to want to check your fan settings. If your fan is set to “ON,” your system will blow air whether your furnace is on or not. That could be why your furnace is blowing cold air. If you switch it to “auto,” it will only blow (warm) air when you need it. If all of this is correct but your furnace is still blowing cold air, there could be a thermostat malfunction. But let’s not conclude that just yet.

Step 3: This step is a little more involved than the other two. If you have a gas furnace, you’ll need to check the gas valve to make sure it’s open. A closed gas valve will prevent you from getting any heat from your furnace! If this isn’t the case, check your pilot light while you’re down there (note: newer furnaces don’t have pilot lights). If your pilot light is out, this could explain why your furnace blows cold air.

Step 4: Consult a professional. We’ve all got our talents. Troubleshooting a furnace just might not be yours. Lucky for you, we do this sort of thing all the time.

Geothermal. Ductless. Ground source. You’ve heard the buzzwords, but what do they mean? If you’re clueless about varieties of heat pump, or just want to learn more, read on.

What Is a Heat Pump?

A heat pump is a heating system that provides warm air by collecting it from outside and pushing it into your house. The principle is the same as that of a refrigerator, but working in the opposite direction. There are several types of heat pumps that all function a little differently.

Air-Source Heat Pump

These are “regular” heat pumps, which pull in heat from the outside air and push it into your home through a ducted HVAC system. These are the most inexpensive heat pump systems to install, but are less efficient and reliable than some of the alternatives.

Geothermal Heat Pump

Also called a “ground-source heat pump,” geothermal heat pumps are better at heating because they draw warmth from the earth, which is generally hotter than the outside air. In addition, the consistency of underground temperatures makes for highly efficiency operation, as there is little variation in the amount of heat the pump draws in.

Geothermal pumps can be expensive to install, but can often save money in the long run, not only in energy savings but also in saved maintenance costs.

Dual-Source Heat Pump

Of course, you can combine both air-source and ground-source heat pumps into a single “dual-source” system. These systems are nearly as efficient as geothermal-only pumps, but cost significantly less to install. However, with an exposed air-source pump, you’ll have all the problems that come along with that system.

Ductless Heat Pump

Also called a “mini-split heat pump,” ductless heat pumps are often used in houses that don’t already have duct systems, or extended to new or renovated rooms. These systems function like window-mounted AC units, drawing air in from the outside and pumping it directly into a room.
They can be very cost-effective when heating small spaces, especially because they don’t rely on ducts (which waste up to 30 percent of energy, according to the U.S. Department of Energy).
However, ductless heat pumps can be obtrusive, as they aren’t built into the walls like a ducted system. In addition, they can be more expensive to install and require technicians with more expertise.

Absorption Heat Pump

Absorption pumps are a little more exotic, as they can be operated using heat sources like gas, propane, or even water heated by geothermal or solar energy. This means they can work in homes without access to electricity, but it also means that they don’t make sense for many residential applications.

However, if you’re interested in exploring more varied sources of energy, absorption heat pumps might provide the flexibility that you’re looking for.

Which Type of Heat Pump Is Right for You?

If you’re confused by these options—and who wouldn’t be—you might want to call a professional. GAC Cooling & Heating can provide expertise and a free estimate for the cost of installing the perfect heat pump system for your home in Maryland. Contact us now to learn more.

A dual-fuel heat pump is a “hybrid” heating and cooling system that combines an electric health pump with either a gas or oil system. Dual-fuel systems are extremely efficient because a computer can control which method it uses to heat your home based on ambient temperature and your own energy use needs.

Dual Fuel Heat Pump Advantages

Electric heat pumps and oil or gas heating systems both have their advantages. Heat pumps rely on existing heat to warm your home. Thus, they function best on warmer days. When the thermometer drops significantly, electric heat pumps have to work very hard to produce the same level of warmth.

On the other hand, oil and gas heat systems can provide a lot of heat, but they’re more difficult to moderate. On very cold nights, the blast of warmth is welcome, but on a mild winter day, it’s often overkill.

Dual fuel heat pumps use energy extremely efficiently by switching between these two kinds of systems based on need and energy efficiency. This means a better experience for residents than either system on its own, and can result in a smaller energy bill at the end of the month.

Is a Dual Fuel Furnace Worth It?

Probably. In a mid-Atlantic climate—like Frederick, MD—where winter temperatures are variable, a dual-fuel system can take advantage of unusually warm winter air to limit your heating to the low-energy electric heat pump. And when the weather gets really chilly, you can still rely on your gas or oil heating to kick on and keep things toasty.

First of all, it’s important to note that it’s normal for external heat pumps to develop some frost in the winter. Most heat pumps have a defrosting mechanism that will periodically melt this icy coating to ensure proper operation. But problems can arise if thicker frost forms, or if the ice stays for too long. To understand why, it’s helpful to know how heat pumps work.

How Heat Pumps Work

Heat pumps need access to outside air to work. They function much like refrigerators, but in reverse, absorbing heat from the cold outside and transferring it into your warm home. This system relies on the flow of air through the pump, as well spinning fans, to get the job done.

During this process, the heat pump creates condensation, and in cold weather that condensation can easily accumulate and freeze. Over time, this can impede the functionality of the pump, and eventually cause damage.

How You Can Tell if Your Heat Pump Is Frozen?

The easiest way to know if your heat pump is frozen is to do a visual inspection. Remember that not all frost is bad—it’s only if it stays around for a while that you might have a problem. Be sure to check back after a few hours to see if the freezing is still there, or has even gotten worse.

Why Is Your Heat Pump Frozen?

There are a few reasons that your heat pump might have frozen over:

  • Weather: Freezing rain or sleet can overwhelm your pump’s normal defrosting process.
  • Debris: Leaves or other debris can block the air flow around your pump, allowing condensation to form.
  • Maintenance: Your pump’s defroster could be dysfunctional, or another element could be promoting ice build-up.

How to Unfreeze the Heat Pump

It’s possible to unfreeze a heat pump on your own, however, it can be tricky. For safety’s sake, you’ll need to ensure it’s turned off before attempting to remove the ice. Doing so with a tool can cause damage, so using warm water is best.

However, heat pumps are delicate devices, and often this fix is only a temporary one. It’s often best to contact a professional who can make a permanent fix.

Have you ever gone to the doctor and felt there was something not quite right about their recommendation? In that case, you go get a second opinion. Sometimes they confirm that the first doctor was right, but sometimes they find another explanation or a simpler solution to your problem. We see the same thing in HVAC all the time.

For instance, recently a Frederick County homeowner came to us for a second opinion. The first HVAC company they called said they would need to replace the heat exchange on their furnace. This is a costly repair that can cost several thousand dollars. Understandably, they wanted to make sure that was the issue, so they called us.

Our technician came and took a look at the furnace, but wasn’t convinced the heat exchange was to blame for their problems. He decided to take a look at their outside vent, just to make sure nothing was blocking it and keeping it from working. Sure enough, the vent was almost entirely blocked by mud dauber wasp nests. We were able to clear that out and resolve their problem for just over $100 rather than thousands. Not to mention replacing the heat exchange wouldn’t have made any difference if the vent was still blocked.

If you ever feel that you’d like a second opinion on your HVAC system, you should never hesitate to ask. In this case, the client asked a different company for a fresh set of eyes, but we even offer second opinions on our technicians. If you ever feel that there’s something more going on or our technician might have missed something, we’ll send another technician to your house at no charge to make sure everything’s in order. In the end, we’re interested in building a long-term relationship with you, and we want to make sure we’ve really solved your problem. Sometimes a second look is all you need.

Whether this is your first opinion or your second, we’d love to talk to you about your HVAC system. Contact GAC today and we’ll help you diagnose your problems, replace your system or get you on a maintenance plan that keeps your system humming all year round.

When it comes to heating your home, you have many different options. You want your home to be heated evenly throughout and for your system to be able to keep up with your home’s heating demands—all while still being economical. A forced air furnace can be a great tool to help you keep your home comfortable throughout the cooler months.

Forced Air Furnaces Defined

A forced air furnace or forced air heating system uses air to help push heat into your home. A system of ducts are used to carry heated air throughout your home. The air is pulled in from the rooms in your home where it then travels through cold-air return ducts. This air then goes through the furnace or heat exchange where it is heated and then pushed back into you home through vents, delivering warm air consistently throughout your home.

You can use your home’s thermostat to control the temperature of the heated air and easily control when you want your home warmed and how warm you want it.

The Benefits of Forced Air Furnaces

There are many benefits to having a forced air furnace installed in your home. Here are just a few:

  • The distribution system can be used to do more than just heat your home. It can also be used to cool and ventilate your home—helping to streamline your home’s heating and cooling systems.
  • The technology involved in forced air furnaces is simple, meaning you save money compared to installing other heating systems.
  • A good forced air furnace will save you money when it comes to energy online slots costs, and it will also put less impact on the environment. Using a programmable thermostat in conjunction with your forced air heating system can save you even more money.
  • There are many different models to choose from. This makes it easy to find one to fit your specific needs.
  • Finding parts and a professional to fix your forced air system if it breaks is easier due to the popularity of these heating systems. It will also be easier to find a professional to give your furnace the regular maintenance it needs to keep it running smoothly.

Install a Forced Air Furnace in Maryland

If you are looking to heat your home more efficiently, you may want to consider having a forced air furnace installed. If you already have duct work in place in your home, then a simple installation can turn your home into a warm and cozy haven. If you are starting from scratch, ductwork can be installed that can then work as an all-in-one system for heating, cooling, and ventilating your home.

Many times, we’ll head out to a Montgomery or Frederick County home for a cooling check and we’ll notice that a heat pump isn’t cooling the home because it is low on refrigerant. Adding a pound of refrigerant to keep the home comfortable for the rest of the season is typical, but when you have a heat pump, that system is working in the winter also. Adding a little refrigerant to get through the summer is common in our industry, but be careful with your heat pump.

During the winter, your heat pump works to heat the home. You can end up damaging the system or end up with a large electric bill two to three times your normal bill because your heat pump stopped working and you didn’t know it and you were heating your home with the electric heat.Typically electric heat is only used for supplemental warmth when it becomes unusually cold. It’s not supposed to heat your whole home all the time, and you don’t want it to because of the high cost.

The moral of this story is that adding coolant to a failing heat pump is a Band-Aid that might end up costing you more in the long run. It also underscores the importance of getting your system checked twice a year, once to inspect the cooling aspects and once to inspect the heating parts of your HVAC system. If your heating and cooling technician warns you that the heat pump will need to be replaced, don’t forget about it. If you aren’t ready to replace it right away, put replacing your heat pump on your calendar for before the first frost. Otherwise, you’ll throw hundreds of extra dollars in the trash for inefficient heat that doesn’t keep you and your family comfortable. No one wants that.

Need more advice on whether your heat pump is salvageable or it’s time to buy a whole new system? Gaithersburg Air is here and ready to help. Whether you’re having a problem right now or need routine maintenance, we help Montgomery County homeowners like you save money with great service and good advice. Contact us today.

When something goes awry with your furnace, you’ll often notice an accompanying smell. In this blog post, our goal is help you associate those furnace smells with the necessary repairs. And, of course, if you decide you need furnace repair in the Gaithersburg or Frederick, MD areas—we know a guy you can call (hint: it’s us. We’re the guy.).

Why Does My Furnace Smell Musty?

If your home is filled with a musty, dry, or dusty smell when you turn your furnace on, you most likely have dust in your combustion chamber. Changing your filter can help! If the smell persists after this, call a professional for further inspection.

Why Does My Furnace Smell Like Gas?

Be careful with this one! If you own and operate a gas furnace, you should be well aware that carbon monoxide is a by-product of its combustion. When your gas furnace is not operating as efficiently as it should, excess and dangerous amounts of carbon monoxide can be produced.

So when you smell gas, it’s usually best to call your gas company in case of a gas leak to avoid fire, explosion, or carbon monoxide poisoning.

Why Does My Furnace Smell Like Rotten Eggs?

Natural gas is actually odorless. A compound is added to it by utility companies to give off a smell so you can more easily detect a gas leak. If you smell rotten eggs or sulfur, this could be a sign that you have a natural gas leak. Shut off your gas supply line (if you know how to) and call your gas company.

If you have a propane furnace and you smell rotten eggs, it’s possible that you’re low on fuel.

Why Does My Furnace Smell Like Burning?

Does your furnace smell like an overheated iron? It’s possible that one of your furnace’s electrical components has failed—especially if you don’t have your system regularly maintained. Call an HVAC company for an inspection.

Geothermal heating is becoming increasingly popular these days. If you’re reading this blog post, chances are you’ve heard of geothermal heating and are wondering if it really can save you money on your heating and cooling bills in Maryland.

The short answer is yes. But let’s rewind just a little.

What Exactly Is Geothermal Heating?

A geothermal heating system is electrically powered unit that transfers the heat stored in the ground to your home. With a geothermal heat pump, the system works in the reverse in the summer—using refrigeration to remove heat from your home. This system differs from air source heat pumps, which draw heat from the air rather than the ground.

This article from National Geographic explains it well:

“Outdoor temperatures fluctuate with the changing seasons but underground temperatures don’t change as dramatically, thanks to the insulating properties of the earth. Four to six feet below ground, temperatures remain relatively constant year-round. A geothermal system, which typically consists of an indoor handling unit and a buried system of pipes, called an earth loop, and/or a pump to reinjection well, capitalizes on these constant temperatures to provide “free” energy.”

Why Do Geothermal Heat Pumps Cost More than Air Source Heat Pumps?

The cost of a geothermal heat pump can be three to five times more than a typical air source heat pump system. This makes sense when you consider the installation process. To install a geothermal heat pump, you must drill into the ground to place the pumps’ loops—which carry the water and anti-freeze solution necessary to transfer the heat in the ground into your home.

Is Geothermal Heating Worth the Extra Cost?

A geothermal heat pump can be 30 to 50 percent more efficient than a typical heat pump—dramatically decreasing your monthly electric bills. According to the Department of Energy, you may recoup your initial investment in as little as two years through lower utility bills.

In addition, because geothermal heat pumps are an environmentally friendly heating and cooling option for your home, the government offers incentives and tax breaks in Maryland for residents who choose to install them. It is estimated that federal and local incentives can cover between 30 to 60 percent of your geothermal unit.
