Geothermal heat pumps are electrically powered heating and cooling systems that transfer ground-source heat from one place to another. Using refrigeration, geothermal heat pumps remove heat stored in the earth and transfer it to your home. During the summer months, a geothermal heat pump works in reverse—transferring the heat stored in your home to the ground. If you’re interested in geothermal heat pump installation in the Gaithersburg, MD area, GAC Cooling & Heating can help. We install geothermal heat pumps in the Montgomery County and Frederick County areas—helping you save money on your heating and cooling bills.
Why Install a Geothermal Heat Pump?
Geothermal heat pumps have been around for over 30 years, but they have risen in popularity lately due to higher energy costs, consumers concern for the environment, and the affordability of a geothermal system through tax credit programs the government offers.
Geothermal heat pumps differ from air source heat pumps in their sources of heat. Geothermal heat pumps draw heat from the ground, while air source heat pumps draw heat from the air. Geothermal heat pumps work better in colder climates and are generally more energy efficient.
The cost of a geothermal heat pump can be three to five times more than a typical air source heat pump system, but they can be 30 percent to 50 percent more efficient than a typical heat pump—dramatically reducing your monthly electric bill. Combined with government incentives and tax breaks, a geothermal heat pump system may not be as big of an investment as you may originally anticipated.
Our Geothermal Heat Pump Installation Process
When we install a geothermal heat pump system, we need to coordinate with a company to drill the well or dig the trenches for the loop. There are two types of loops: a closed loop and an open loop. A closed loop is a term used to describe the plastic pipe buried in the ground. This pipe is connected to the indoor heat pump to form a sealed or a “closed loop” system. Inside the closed loop, a mixture of water and anti-freeze solution transfers the heat from the ground to the heat pump system. With an open loop system, a well is drilled and water is pumped up through the system and then back into the ground.
Depending on your application, your land, and other factors, GAC Cooling & Heating will help you determine what type of loop is best for you.

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.
