Frequently Asked Questions Regarding Geothermal Heating and Cooling
Have questions about geothermal heating and cooling? We have the answers to your frequently asked questions!
How long does a geothermal system last? Thanks to the durability of geothermal heat pumps, these units can perform reliably for 15 to 20 years. Then, the underground portion of the geothermal heating and cooling system comes with up to a 50-year warranty.
How much space does it take up? A majority of the system is installed underground. Multiple layouts are available, including a Slinky-type loop system that requires the least amount of space underground if land is limited. The remaining components are located inside your home and take up about the same amount of space as a traditional furnace.
Does frozen soil present a problem? No, as long as the system is designed properly and installed at the correct depth.
What about comfort? Geothermal heating and cooling uses your existing ductwork to circulate warm air (90 to 105 degrees) around your home. Cycles are longer since the air isn’t piping hot, but this is beneficial because it evens out hot and cold pockets that form in homes with traditional HVAC systems.
How does efficiency compare? Furnaces can achieve up to about 94 percent efficiency. Since geothermal systems move heat instead of generating it from a combustible fuel source, they can achieve around 400 percent efficiency. This results in up to 70 percent savings on your monthly energy bills.
What makes these systems so eco-friendly? The Department of Energy and Environmental Protection Agency back geothermal heating and cooling systems because they conserve natural resources, consume very little electricity, minimize ozone depletion, and emit no harmful greenhouse gases.
What incentives are available for installing geothermal heating and cooling? Check into federal tax credits for qualified geothermal systems. These credits amount in 30 percent of the total cost (no upper limit; existing homes and new construction both qualify).
To learn more about upgrading to a geothermal heating and cooling system, please contact Sobieski Services in Wilmington. Our goal is to help educate our customers in Delaware, Pennsylvania, Maryland and New Jersey about energy and home comfort issues (specific to HVAC & plumbing systems).
