Our Geothermal Experience

Chelsea has been installing and maintaining geothermal systems since 1978 and stands at Chester County’s forefront in the installation of this innovative technology.

A geothermal system produces extemely high levels of efficient energy because a geothermal heat pump only uses electricity to move heat; not to produce it. A geothermal unit typically supplies four to five kilowatts of heat for every killawatt used. Three to four of these kilowatts of heat come directly from the earth itself, and are clean, free and reusable. For more go to our geothermal page.

Geothermal systems tap the constant temperature of the earth in order to provide heating, cooling
and hot water. Your home stays comfortable all year round while trimming your energy bill up to 80%.
And by taking advantage of new federal tax credits that won't expire until December 2016 (check with your state), you’ll also save 30% - on your TOTAL installation.
