Geothermal Energy

Use the earth as a heat source to provide heating, cooling and hot water for homes.

In the winter...
Heat is absorbed from the ground or groundwater and carried to the geothermal unit via an underground piping system or well. The heat is transferred to the air, which is distributed through duct work similar to that used in any forced air heating system.


In the summer...
The unit provides central air conditioning by rejecting heat from your home. A portion of the heat can be used to produced hot water, while the remainder is pumped back to the underground piping or well system, where it harmlessly dissipates into cooler ground/water.


 Option GT
New – installation of new geothermal system | Retrofit – replacement of heat pump for an existing geothermal system.

Our rebate is based on the unit’s Energy Efficiency Ratio [EER] rating. Geothermal units must be independently verified through the current Air Conditioning and Refrigeration [ARI] directory as performing to our Efficiency standards.

Geothermal Energy Highlights

  • Efficiency - Geothermal systems are up to four times as efficient as the most efficient fossil fuel furnace. Instead of burning a combustible fuel to make heat, they simply move heat that already exists.
  • Cost Savings - Geothermal systems not only cut your heating and cooling costs, they often provide hot water at substantial savings.
  • Durability - Geothermal systems last longer than conventional systems because they are protected from harsh outdoor weather. The unit is housed entirely indoors.
  • Conservation - Geothermal systems work with the environment by absorbing renewable, non-polluting solar thermal energy stored in the earth and groundwater, and using that energy to heat and cool your home.
  • Low Maintenance - Geothermal systems have fewer mechanical components, making them more reliable and less prone to failure. The ground loop has an expected life of over 50 years and requires no maintenance.
