Dedicated to the Promotion of Efficient Ground Source Energy in Connecticut Buildings
Welcome to the Connecticut Geothermal Association

The purpose of the Connecticut Geothermal Association is to promote and enhance ground source heating and cooling systems for new and existing buildings throughout the Constitution State.
Our mission is to develop the ground source (also known as geothermal) industry.
If you are work in the geothermal heating & cooling industry in Connecticut, we invite you to visit and/or join our group.
What is Geothermal Heating & Cooling?
Geothermal systems use technology known as ground source heat pumps to make the transfer of hot and cool air more efficient.
Because the system works with the relatively constant temperature of the earth, instead of the variable temperatures above ground, geothermal heating and cooling systems use 40-60% less energy than conventional systems.

BREAKING NEWS!
The 30 percent federal income tax credit is back until December of 2019! This credit is for homeowners updating a current heating system and for new construction. This credit is inclusive of the entire geothermal heating and air conditioning system with the exception of the duct work. Again this is a tax credit not a rebate. If you didn’t pay enough in taxes the year its installed you get to claim it again on the following years taxes until the full 30 percent is back in your pocket.
