Why Geothermal?
The Case for Ground-Source Energy
Geothermal isn't just an alternative — it's the most efficient, longest-lasting, and cleanest heating and cooling technology available for New England buildings.
Key Advantages
Why Building Owners Choose Geothermal
Up to 70% Energy Savings
Geothermal systems deliver 3-5 units of energy for every 1 unit of electricity consumed. Homeowners routinely see 50-70% reductions in heating and cooling costs from day one.
Zero Direct Emissions
No combustion, no flue, no fossil fuel burned on-site. Geothermal is the only HVAC technology that eliminates direct carbon emissions entirely.
Built for New England
Unlike air-source heat pumps that lose efficiency below 20°F, geothermal taps the constant 55°F underground temperature — reliable performance even in January.
Near-Silent Operation
No noisy outdoor compressor unit. The entire system operates quietly indoors — no impact on your property's appearance or your neighbors.
50+ Year Ground Loop Life
HDPE ground loops are warrantied for 50+ years. Indoor heat pump units last 25+ years — far outlasting furnaces (15-20 yrs) and air-source units (12-15 yrs).
Increases Property Value
Studies show geothermal homes sell for 6-8% more. Low operating costs and long equipment life are a strong selling point for buyers.
Heating + Cooling + Hot Water
One system does it all — heating in winter, cooling in summer, and optional desuperheater provides free domestic hot water year-round.
Energy Independence
Eliminate dependence on volatile oil and gas prices. Your "fuel" is the constant temperature of the earth beneath your property — free and unlimited.
System Comparison
Geothermal vs. Traditional Systems
See how ground-source heat pumps compare to conventional heating and cooling technologies across every metric that matters.
| Feature | Geothermal | Oil / Gas Furnace | Air Source Heat Pump |
|---|---|---|---|
| Efficiency Rating | 300–500% (COP 3–5) | 80–95% AFUE | 200–300% (COP 2–3) |
| Operating Cost | ★ Lowest | High (fuel volatile) | Moderate |
| Cold Climate Performance | ★ Consistent at 55°F ground | Good (burns fuel) | ✕ Degrades below 20°F |
| Both Heating & Cooling | ✓ Yes | ✕ Heating only | ✓ Yes |
| Lifespan (Indoor) | 25+ years | 15–20 years | 12–15 years |
| Lifespan (Ground Loop) | 50+ years | N/A | N/A |
| Carbon Emissions | ✓ Zero direct | ✕ High (combustion) | Low (electric) |
| Noise Level | ★ Near silent | Moderate | Moderate (outdoor unit) |
| Federal Tax Credit | ✓ 30% uncapped | ✕ None | Limited |
| Maintenance | ★ Minimal | Annual tune-up + fuel | Moderate |
The Economics
How the Numbers Work
Total system cost including drilling, ground loop, and heat pump for typical residential
After incentives, most systems pay for themselves in energy savings within 5-8 years
After payback, the ground loop keeps working for 40+ more years at near-zero marginal cost
