Geothermal Systems
When it comes to keeping you comfortable, lowering utility costs, and conserving natural resources, geothermal systems offer a proven solution that's not only practical, but readily available.
Nothing Compares to the Efficiency of Geothermal Systems
A geothermal heat pump can save half the cost of heating and cooling the average home. In fact, for every unit of energy used for operation, three to five units of heat energy are produced.
In other words, for every $1 you spend on running the heat pump and blower, $3 to $5 worth of energy is delivered.
For even further energy savings, Comfort-Aire geo heat pumps include hot water generators that supplement domestic hot water (in both the cooling and heating modes).
Not only is geothermal technology efficient, it's also effective at keeping your home comfortable in every season.
Energy Efficient & Earth Friendly
How our geothermal systems work...
- Piping or tubing is buried in the ground or submerged in a pond or lake.
- A water/coolant mixture circulates through the piping.
- In summer, hot air is extracted from the home by the heat pump and absorbed by the water mixture. This heat is transferred to the ground or pond water as the water mixture travels through the piping, and cooled water is returned to the heat pump.
- In winter, the water mixture in the piping absorbs heat from the ground or pond/lake and transfers it to the heat pump.
- The heat pump blower distributes the conditioned air throughout the home.

Residential Energy Use
Conventional System
Breakdown: Lighting 3%, Appliances 11%, Hot Water 22%, Heating & A/C 64%.
Geothermal System
Breakdown: Lighting 3%, Appliances 11%, Hot Water 16%, Heating & A/C 19%, Free Geothermal 51%.
With a Geothermal system, over half your home's energy is free.
Geothermal Advantages
- Energy efficient: Energy is needed only to pump the water solution and to run the geo system's blower, efficiency ratings reach as high as 27.3 EER* and 5.0 COP (full load).
- Extended operating range: Allows geothermal to work in virtually every climate.
- Quiet operation: Cabinet insulation and compressor mounting system dampen vibration and associated sound.
- Safety: No gas or oil is used, there are no fumes, and no odors.
- Long life: There are fewer moving parts to wear out than on a conventional heating/cooling system.
- Proven technology: Recognized by the EPA and the U.S. Department of Energy.
Exceptional Efficiency Means Fast Payback
Although the initial cost of a geothermal system is higher than a conventional heat pump or furnace/condenser combination, you can quickly recoup these costs through energy savings and potential Federal tax credits.
On average, geothermal heat pumps provide:
- 40% greater efficiency than air-to-air heat pumps.
- 48% greater efficiency than gas furnaces.

They're also eligible for Federal tax credits. Ask your dealer to prepare a cost savings analysis for you to determine just how much you can save!
*EER-Energy Efficient Ratio, COP-Coefficient of Performance
The relative stable temperature of the ground or water at 5 feet below the surface allows heat transfer to occur in summer or winter.
Installation Flexibility
Geothermal offers many options in terms of installation, so you can select the system that best meets your personal preferences, your geographic area, and the availability of land or ground water. When properly designed, all systems work equally well.
