Geothermal HVAC
The most efficient heating and cooling available — using the earth's own temperature.
Geothermal (ground-source heat pump) systems use the stable temperature of the earth — roughly 55°F year-round in our region — to heat and cool your home with exceptional efficiency. Junior Collins HVAC provides geothermal system service and consultation for new geothermal installations on qualifying properties.

Financing, Rebates & Tax Credits
Federal Investment Tax Credit — 30%: Ground-source (geothermal) heat pump systems qualify for a 30% federal tax credit on total installed cost through 2032, with no dollar cap. This is the largest available credit for residential HVAC work.
Air-Source Heat Pump Comparison: If a geothermal system isn't feasible for your property, air-source heat pumps qualify for up to $2,000 in annual federal tax credits — still significant.
Utility Financing: Some utility providers offer low-interest financing for geothermal installations. Ask us about options for your utility territory.
Tax credit eligibility depends on equipment specifications and your individual tax situation. Consult a tax professional for details. Ask us about current utility rebate programs when you request your quote.

FAQ
Common Questions
Is geothermal practical in western North Carolina?
Yes. The ground temperature in our region stays at approximately 55°F year-round, which is the foundation of how geothermal systems work. They're most practical for new construction and properties with enough land for a horizontal loop (roughly 1,500 sq ft per ton of capacity) or access to a suitable well for a vertical loop.
How efficient is geothermal compared to a standard heat pump?
Geothermal systems typically deliver 3–5 units of energy for every 1 unit of electricity consumed, compared to 2–3 for an air-source heat pump. The higher upfront cost (typically $15,000–$30,000+ installed) is offset by significantly lower operating costs over 20+ years — and the 30% federal tax credit substantially reduces first cost.
What's a desuperheater on a geothermal system?
A desuperheater captures waste heat from the geothermal refrigeration cycle and uses it to preheat domestic hot water. On average, a geothermal desuperheater can provide 50–70% of a home's hot water at no additional energy cost during heating and cooling season.
Does geothermal qualify for tax credits?
Yes — one of the best incentives available. Residential geothermal heat pump systems qualify for a 30% federal investment tax credit on total installed cost (including ground loop installation) through 2032. This credit applies with no dollar cap.
