Geothermal Heating and Cooling FAQ

Did you know the answer to heating and cooling your home could be underneath your feet? In Michigan, the underground temperature hovers around 50 degrees Fahrenheit year-round. Ground source heat pumps then transfer heat energy from your home or commercial building to the underground and vice versa. Water source heat pumps transfer heat from your building to a nearby pond or lake.

Heat pumps improve the energy efficiency of your home and save you money on utility bills. To help you better understand the benefits of geothermal heating and cooling, we recommend checking out our list of frequently asked questions and contacting a geothermal heat pump contractor.

How does geothermal heating and cooling work?

A geothermal heat pump works by moving heat energy from one place to another. A geothermal heating system removes heat energy stored underground or in a nearby body of water and transfers it to your home or commercial building.

In the summer, this process reverses so that the heat in your building is exchanged with cool underground temperatures. There are many different types of geothermal heat pump systems, such as ground and water source heat pumps.

How is heat transferred from the ground or water into a home or business?

An antifreeze solution is pushed through a series of tubes buried underground or submerged in water. The antifreeze solution carries geothermal heat energy to a heat exchanger where it’s exchanged with cold indoor temperatures.

This process is reversed during the summer months when heat energy is taken from your home and transferred with the cooler underground temperatures. Depending on the season, the heat pump system will either heat or cool your home so it stays at a comfortable temperature year-round.

Do I need separate geothermal ground loops for heating and cooling?

No. A closed loop geothermal heat pump system is capable of both heating and cooling. When shifting from heating to cooling, and vice versa, the flow of heat is simply reversed by a mechanism inside the geothermal heat pump system.

Where will the geothermal loop be installed?

Where we install the geothermal loop depends on land surrounding your house. If your property is big enough, we may be able to install closed loop systems horizontally adjacent to your home. For small properties, we are able to install a vertical geothermal loop system.

If you are lucky enough to own a pond or lake, we can install the tubes needed for a geothermal system at least eight feet under the surface to prevent freezing. Water source heat pumps are the most affordable geothermal energy option for homeowners.

How much does it cost to install a geothermal heating system?

According to homeadvisor.com, the average cost of geothermal heating installation is $7,151. In comparison, it costs an average of $4,179 to install a furnace.

Will geothermal heating and cooling save money on energy bills?

Yes. However, you’ll have to pay more in the short-term to install geothermal heat pumps than you will for other types of home heating systems.
