About Geothermal Heat Pumps

Geothermal systems use the stable temperature of the earth to heat and cool your home with exceptional efficiency. While installation costs are higher, they offer the lowest operating costs of any HVAC system.

📋 Important Considerations

•Site Assessment: Professional evaluation of soil conditions, available land, and home heating/cooling load is essential
•Loop Field: Vertical loops require drilling 150-400 ft deep. Horizontal loops need 1/4 to 3/4 acre of open land
•Ground Loop Warranty: Most ground loops come with 50-year warranties and can last even longer
•Federal Tax Credit: 30% tax credit available through 2032, then phases down
•Financing: Many utilities and states offer special financing for geothermal installations
•Best for New Construction: Ideal during new builds, but retrofit installations are common
