How Does a Heat Pump Work?

Heat pumps are becoming an increasingly-popular choice for homeowners to heat and cool their homes. Keep reading to learn how a heat pump can help keep you comfortable all year long.

The key difference between heat pumps and other HVAC systems is that heat pumps do not actually generate heat. Instead, they transfer heat from one place to another to keep your home at your desired temperature. For this reason, heat pumps can also be used to cool your homes, though they generally work best in moderate climates.

So, how exactly do heat pumps work? There must be both a “heat source” and a “heat sink”. The heat source can be the air or the ground. Even air that feels cold still has heating energy present and can therefore be used as a heat source. The heat sink is the place where the heat gets directed to. During the winter months, the heat sink is your home.

A heat pump utilizes a compressor to constantly circulate refrigerant through cycles of evaporation and condensation. When the refrigerant reaches the evaporator coil, it turns into a gas and absorbs heat from its surroundings (the heat source). This refrigerant is then compressed and transferred to the condenser coil, where is turns back into a liquid and releases the heat into the heat sink (your home).

During the summer months, the process is reverse. Your home acts as the heat source, and the outside becomes the heat sink, allowing the unit to effectively function as an air conditioner. This all-in-one system is not only convenient for homeowners, it is very energy-efficient since no heat needs to be created from fuel.

Different Ways to Heat Your Home This Winter

Times are changing in the world of HVAC. Unlike the past, homeowners today have several options when it comes to keeping warm during the winter months. If you are in the market for a new heating system, here are a few options you can consider:


Furnaces are one of the oldest, and by far the most popular, methods of home heating in the United States. Also known as a forced-air system, the furnace burns gas (oil, natural gas, or propane) to generate heat, and blows this hot air through ducts to heat your home.


Unlike furnaces, which heat air, boilers rely on hydronic (water) heating to warm your home. These systems heat water and distribute it through radiators, which release warmth into the air. The water is then returned to the boiler where it is re-heated.

Ductless Heating

As you can tell by the name, a ductless heating system (also referred to as a “mini-split system”) does not require the use of air ducts. Instead, the combination of an outdoor compressor and multiple indoor air-handling units are used to keep your home at your desired temperature.

Radiant Heat

Radiant heating is a relatively new technology that is gaining popularity. A radiant heating system heats tubes under the floor, thus warming the floor and causing this heat to rise throughout your home. The best part? No more cold feet!

Heat Pump

Despite the name, heat pumps can be used to heat or cool your home. They are essentially a two-way air conditioner; removing heat from your home during the summer months, and bringing it into your home (with the help of an electrical system) during the wintertime.

No matter how you plan keeping warm this winter, trust the experts at Air Treatment Company to keep your heating system running in tip-top shape. We offer HVAC repairs, installations, and replacements for all makes and models of systems. If you live in Fairfax County, Virginia, contact us online or give us a call at (703) 938-0550.

Things To Consider When Replacing Your Home's Heat Pump

​Heat pumps can heat and cool your home for 10 to 15 years. Has your heat pump far exceeded this lifespan? If so, consider replacing it. Below are some tips to keep in mind when replacing your home’s heat pump.

First and foremost, start with a realistic budget for your new heat pump. Think about how much money you would feel comfortable spending on a new system. This will prevent you from spending an astronomical amount of money. In the best case scenario, it will also help you save money. It’s a win-win situation!

Energy Efficiency
Another major factor that can have an impact on your decision is energy efficiency. Plenty of homeowners want to “go green.” After all, there are two benefits to this–it can help you conserve energy, and it also saves you money. A heat pump that is purchased in 2016 is bound to be more energy efficient than one that was purchased 15 years ago. If energy efficiency is important to you, choose a heat pump with a SEER rating of 13 or above. The higher the rating, the more energy efficient it is.

Signs You Need A New Heat Pump

Heat pumps are not meant to last forever. If a heat pump in an older home has never been upgraded, a replacement is probably in order. Below are some indications that you need to invest in a new heat pump.

Old Age
When it comes to your heat pump, age is not just a number. Heat pumps have a life expectancy of 10 to 15 years. If your heat pump has exceeded this range, a replacement is your best bet.

Poor Performance
Do you have unseasonably high utility bills? Does your heat pump require frequent repairs? If you answered yes to either of these questions, your heat pump is not performing at peak efficiency. A new heat pump can remedy the situation.

An Uncomfortable Home
Your heat pump is supposed to make your home feel more comfortable. If you find yourself feeling cold in the wintertime and uncomfortably warm in the summertime, your heat pump has seen better days. It’s time to upgrade!
