Just as air source heat pumps use outdoor air to heat or cool the home, geothermal heat pumps utilize energy stored in the ground to manage indoor temperatures. They feature a “closed loop” of underground piping that serves as the exchanger transferring heat to or from your central HVAC system throughout the year.
By moving heat to and from the earth instead of burning fossil fuels like a traditional furnace, geothermal heat pumps have virtually no environmental impact. And when it comes to cooling, the more consistent underground temperature makes them up to twice as efficient as air source pumps and central AC units.
According to the U.S. Department of Energy, geothermal heat pumps (GHPs) can reduce energy bills by up to 65 percent compared to traditional HVAC systems. The resulting energy savings offset the higher installation costs over time, usually within 10 years.
Homeowners can claim a federal tax credit for 26% of their GHP installation through December 31, 2022. The incentive will drop to 22% for systems installed in 2023.
A GHP system is a long-term investment that pays itself off long before needing replacement. And with up to 65 percent more efficiency than traditional HVAC systems, GHPs typically pay off their higher installation costs within 10 years.
GHP systems use less electricity and rely on free, renewable energy from the ground to heat or cool the home, effectively reducing your carbon footprint as well as your utility bills. Additionally, they don’t produce carbon monoxide or any other pollutant greenhouse gases.
Offering enhanced dehumidification and air purification, GHPs provide improved indoor air quality. And since they don’t require the combustion of a fuel-burning furnace, GHPs don’t produce carbon monoxide that can potentially leak into the home and pose a health hazard for you and your family.
GHPs don’t require a noisy outdoor condensing unit like traditional AC systems, and the indoor components are engineered for smooth and quiet operation. And beyond cleaning/changing the filter and annual inspections from an HVAC professional, you can expect little to no maintenance with your GHP.
The closed loop system transfers energy from the ground to the home for heating. In the summer, the GHP system cools the home by pulling heat from inside and releasing it to the ground. That means year-round comfort with the convenience of one system.
