What Is a Heat Pump, Anyway?

Modern air conditioners use a simple cooling cycle to remove heat from buildings. The refrigerant chemicals absorb heat at the indoor coil, becoming gaseous in the process. Then the system pumps the refrigerant over to the outdoor coil, where it is compressed back into liquid form. In the process, the heat is released outside the home; the refrigerant then returns to the indoor coil to repeat the process. Because no refrigerant is actually consumed in the process, air conditioners run quite efficiently, even in very hot weather.

So if you're wondering, "what is a heat pump?" - A heat pump is essentially a reversible air conditioner. During the cooling season, the system collects heat inside the house and expels it outside, just like a standard air conditioner. During the heating season, the cycle runs backward, absorbing heat outside and bringing it into the home.

The Many Benefits of Heat Pumps

Because they essentially combine two systems in one package, heat pumps are a great way to save space in smaller homes. They run very efficiently, especially in areas with fairly mild winter temperatures. Unlike furnaces, which would require one of our Sterling, VA furnace repair technicians, and boilers, heat pumps don’t need to burn fuel to heat your home; they just use the power of the cooling cycle to bring in heat from the outside air. Many of our friends and neighbors have had great success heating and cooling their homes with heat pumps.

We offer annual service agreements to keep those essential systems running at peak efficiency during the heating and cooling seasons alike.
