Common Questions

Frequently Asked Questions

Everything you need to know about geothermal heating, cooling, and finding the right contractor.

What is geothermal heating and cooling?

Geothermal heating and cooling uses the earth's constant underground temperature to heat and cool buildings. A geothermal heat pump circulates fluid through underground pipes (ground loops) to exchange heat with the earth, providing efficient heating in winter and cooling in summer. These systems can reduce energy costs by up to 70% compared to conventional HVAC.

How much does a geothermal system cost?

A residential geothermal system typically costs between $15,000 and $35,000 installed, depending on system size, loop type, and soil conditions. However, the 30% federal tax credit under the Inflation Reduction Act can reduce costs by $4,500–$10,500. Most homeowners see payback within 5–10 years through energy savings of 40–70%.

How do I find a qualified geothermal contractor?

Use Geothermal.contractors to search our directory of 900+ verified geothermal installers across all 50 states. Filter by location, services, and certifications. Look for contractors with IGSHPA certification, proper licensing, and experience with your specific project type (residential, commercial, or retrofit).

Is geothermal worth it in 2026?

Yes. With the 30% federal tax credit available through 2032, rising energy costs, and systems lasting 25–50+ years, geothermal offers excellent long-term value. A typical household saves $1,000–$2,500 annually on heating and cooling costs while reducing carbon emissions by 5–8 tons per year.

What types of geothermal loop systems are available?

There are four main types: horizontal closed-loop (trenches at 4–6 feet deep, best for large lots), vertical closed-loop (boreholes 150–400 feet deep, ideal for small lots), pond/lake loop (submerged coils in a nearby water body), and open-loop (using well water directly). Your contractor will recommend the best type based on your property, soil, and budget.
