Frequently Asked Questions
How much does geothermal installation cost in Indianapolis?
Geothermal installation in Indianapolis costs $15,000-$30,000 before incentives. Federal tax credit (30%) reduces cost by $4,500-$9,000. Many states and utilities offer additional rebates. Payback period: 5-10 years.
How does geothermal heating and cooling work?
Underground loops circulate fluid that absorbs earth's constant temperature (50-60°F). In winter, the heat pump extracts warmth from the fluid. In summer, it dumps heat into the ground. 300-400% efficient vs 95% for gas furnaces.
How long does a geothermal system last?
Indoor heat pump components last 20-25 years. Underground loops last 50+ years. This means you only replace the indoor unit — the most expensive part (the ground loop) is essentially permanent.
