Save Thousands on a Geothermal System

Geothermal technology moves energy from the sun that is stored in the earth to provide heating, air conditioning, and hot water. With thousands in rebates available, it’s never been easier — or more affordable — to switch to the most efficient and eco-friendly technology available.

How it works

Geothermal (also known as ground-source) heat pumps transfer heat stored in the earth into your building during the winter, and transfer it out and back into the ground during the summer to keep your space cool.

The system includes three principal components:

  1. Ground Loop
    A series of connected pipes buried in the ground circulate water to absorb heat from, or relinquish heat to, the surrounding soil, depending on whether the system is providing heat or cooling. In other words, the system uses the earth as a heat source during winter and a heat sink during summer.
  2. Heat Pump
    The mechanical system that compresses a refrigerant to efficiently move heat into or out of a building. During winter, the heat pump removes heat from the water in the ground loop and transfers it to the building. During summer, the process is reversed.
  3. Heat Distribution Subsystem
    Conventional ductwork is generally used to distribute heated or cooled air from the geothermal heat pump throughout the building.


  • Uses energy more effectively. Heat pumps concentrate and transfer heat rather than generating it directly, delivering one-and-a-half to three times more heat energy to a building than the electrical energy they consume   
  • Dual heat-and-cooling system
  • Systems equipped with desuperheaters can also produce hot water by transferring excess heat from the pump’s compressor to the building’s hot water tank   
  • Cost savings   
  • Whisper quiet
  • Lower emissions
  • Filters and dehumidifies the air
  • Easy to operate
  • No visible or exposed outdoor equipment

Save Thousands on a Geothermal System

Receive thousands in incentives for a home geothermal system with up to 300,000 Btu/h of total system heating capacity.

Get additional incentives if you install a desuperheater to supplement your existing water heater, or ground-source, heat-pump water heater.

When combined with federal tax credits, you could save tens of thousands of dollars when you install geothermal!

Pick a participating contractor to get started. Your contractor will help find and install your heat pump, and deduct your rebate from the total project cost.
