At Comfort Pro, we like to ensure our customers are well-informed on their purchase decision before any charges are made. Geothermal systems are among the most energy efficient HVAC units on the market. No other unit comes close to geothermal in actual monthly savings immediately after installation. But all homeowners have questions about it before their purchase, so we’ve compiled some frequently asked questions (FAQ) about geothermal for your convenience! If you have any question not answered here, feel free to contact us at any time.
