Advanced Geothermal Systems for Eco-Friendly Comfort
Geothermal systems offer one of the most energy-efficient and environmentally friendly ways to heat and cool your home. At Envirotemp, we specialize in geothermal HVAC solutions that deliver reliable comfort, lower energy costs, and long-term savings for homeowners throughout Delaware.
Unlike traditional heating and cooling systems, geothermal technology uses the stable temperature beneath the earth’s surface to regulate your home’s comfort. This allows your system to work more efficiently in every season—keeping your home warm in winter, cool in summer, and comfortable year-round.

TURNKEY INSTALLATION
"Envirotemp installed two Water Furnace systems in our new home in 2007. The units work great. Mike promised a turnkey installation and he delivered. This included ductwork, well drilling, air cleaners, and submitting all rebate forms. I am very pleased with my geothermal systems."

GREAT JOB!
"My wife and I are very "thankful" for the great job done to upgrade our A/C and heater. The old system was a money pit and Evirotemp installation of the new system has been very cost effective with heat in winter and a/c in the summer. Very efficient and cost less to run."
