Do You Need Air Ducts with a Geothermal System? A Cincinnati Geothermal Question

Geothermal systems are a great way to heat and cool your home using the energy in the earth. For homeowners that are looking to reduce the amount of energy that they use to condition their home’s air, geothermal systems are one of the best ways to do that. We thought it would be helpful if we put together a quick explanation of how they work. If you need geothermal system installation or repairs in Cincinnati, call RineAir Heating & Air Conditioning.

How Geothermal Systems Work

If you were to dig down about 10 feet into the ground the temperature there is about 55° F all year long. No matter what temperature the air is above the ground the earth stays about the same temperature. Geothermal systems work by taking advantage of that temperature consistency.

Geothermal systems are able to take advantage of that energy using a series of pipes buried in the ground. During installation, your HVAC contractor will dig out a large area of your yard and put in a ground loop. For this reason, geothermal systems can only be installed at homes that have a large enough area for this ground loop.

The Geothermal Heat Pump

Inside your home, a heat pump will do the work of extracting heat out of the ground. The heat pump will circulate refrigerant through the loops in the ground where it will absorb heat and carry it back to the heat pump. The fan in the heat pump will blow air over a series of coils where the refrigerant expels its heat.

Air Ducts

After the heat is pulled out of the refrigerant, the fan in your heat pump will push the newly heated air through the ducts in your home. The ducts carry the heat through your home and to each of your individual rooms.
