Residential Geothermal
Heating & Cooling
Cut your home energy bills by 30–70% with a geothermal heat pump system. Enjoy consistent comfort, whisper-quiet operation, and free hot water — all powered by the stable energy beneath your yard.
Why Homeowners Choose Geothermal
Residential geothermal heating and cooling is the most efficient, reliable, and environmentally friendly way to heat and cool your home — delivering 30–70% energy savings with a system that lasts 25+ years.
30–70% Lower Energy Bills
Homeowners typically save 30–70% on heating and cooling costs compared to conventional furnaces and air conditioners.
30% Federal Tax Credit
The Inflation Reduction Act provides a 30% federal tax credit on residential geothermal installations through 2032 — no cap.
50+ Year Ground Loop Life
The underground loop system lasts 50+ years. Indoor equipment lasts 20–25 years — double the lifespan of conventional HVAC.
Whisper-Quiet Operation
No noisy outdoor condenser units. Geothermal heat pumps operate quietly indoors, providing peaceful comfort year-round.
Free Hot Water
A desuperheater captures waste heat to preheat domestic hot water, reducing water heating costs by up to 50%.
Zero Carbon Emissions
No fossil fuels burned on-site. Geothermal is the cleanest, most environmentally friendly way to heat and cool your home.
How Residential Geothermal Works
A geothermal heat pump uses the earth's constant underground temperature to heat your home in winter and cool it in summer — all from one compact indoor unit.
Just a few feet below the surface, the ground stays at a remarkably stable 50–60°F year-round, regardless of the weather above. A residential geothermal system taps into this free, renewable energy source through a network of underground pipes called a ground loop.
In Winter (Heating Mode)
Fluid circulating through the ground loop absorbs heat from the earth and carries it to the indoor heat pump. The heat pump concentrates this energy and distributes it through your ductwork or radiant floor system, warming your home efficiently — even when it's below zero outside.
In Summer (Cooling Mode)
The process reverses. The heat pump extracts heat from your indoor air and transfers it to the cooler earth through the ground loop. This is far more efficient than an air conditioner, which must dump heat into the already-hot outdoor air.
Loop System Options
Vertical loops are ideal for smaller lots — boreholes are drilled 150–300 feet deep. Horizontal loops work well with larger yards — trenches are dug 4–6 feet deep. Pond/lake loops are an economical option if you have a nearby water source. Your contractor will recommend the best option for your property.
The Installation Process
Home Energy Assessment
A certified geothermal contractor evaluates your home's heating and cooling loads, insulation, ductwork, and lot characteristics to design the optimal system.
Ground Loop Installation
Depending on your property, vertical boreholes (150–300 ft) or horizontal trenches (4–6 ft deep) are drilled to install the underground loop system.
Indoor Equipment Setup
The geothermal heat pump unit is installed indoors — typically in a utility room, basement, or closet — and connected to your existing ductwork or hydronic system.
System Commissioning
Your contractor tests, balances, and commissions the system. You'll enjoy immediate savings with consistent, comfortable temperatures in every room.
Residential Geothermal Cost & Savings
A residential geothermal system typically costs $18,000–$45,000 before incentives. After the 30% federal tax credit and state incentives, your net cost could be significantly lower — with payback in just 5–10 years.
- Average installed cost: $18,000–$45,000 (before tax credits)
- 30% uncapped federal tax credit — save $5,400–$13,500+
- Additional state and utility rebates available in many areas
- Monthly energy savings of $100–$300+ for typical homes
- Typical payback period: 5–10 years
- Increases home resale value by $10,000–$25,000
