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.
  • Reduced maintenance costs
  • Whisper quiet
  • Lower carbon emissions
  • Easy to operate
  • No visible or exposed outdoor equipment

Get $150 Off a Desuperheater for Your Geothermal System

If you already have geothermal, you can earn $150 if you install a desuperheater to supplement your existing water heater.

A desuperheater is a small, auxiliary heat exchanger that uses superheated gases from the heat pump's compressor to heat water. This hot water then circulates through a pipe to a storage water heater tank.

In the summer, the desuperheater uses the excess heat that would otherwise be expelled to the ground to heat your water. During the fall, winter, and spring—when the desuperheater isn't producing as much excess heat—you'll need to rely more on your storage or demand water heater to heat the water. You can install a triple-function geothermal heat pump system, to meet your hot-water needs year-round.

Save Thousands on a Geothermal System

Get up to $5,000 per 10,000 Btu/h of heating capacity off a geothermal system—up to 300,000 Btu/h total. Multifamily and commercial customers are eligible for incentives on geothermal installations larger than 300,000 Btu/h as a custom incentive at $200/MMBTU of annual energy savings.

If your building is in the area affected by the Westchester natural gas moratorium, you can receive an incentive increase of 30% above the current incentive rates. Category 9 projects (simultaneous installation of space heating water heating) are not eligible for additional rebates.

Find a participating contractor in the New York State Clean Heat Program. Your contractor will help find and install your heat pump, and deduct your rebate from the total project cost.
