20-year geothermal vs conventional HVAC comparison
Quick Cost Estimate
Formula
Install Cost = System Tons × Cost per Ton; Net Cost = Install − (Install × 30% ITC); Annual Savings = Current HVAC Cost − Geothermal Operating Cost; Payback = Net Cost / Annual Savings
Frequently Asked Questions
How much does geothermal installation cost?
A typical residential geothermal system costs $18,000-$45,000 before incentives, depending on system size, loop type, and soil conditions. After the 30% federal ITC, costs drop to $12,600-$31,500. Vertical loop systems cost more but require less land area.
Is geothermal worth it in my climate?
Geothermal works in all climates because ground temperature is constant year-round (50-60°F in most US regions). It's most cost-effective where heating/cooling costs are high, especially for homes using oil, propane, or electric resistance heating. Even in mild climates, the high efficiency provides savings.
