Choose a geothermal heat pump
Geothermal heat pumps, also called ground-source heat pumps, use 45% less energy than standard options. If your current air-source heat pump needs to be replaced—typically when it is more than 12 years old—think about choosing a geothermal heat pump.
How it works:
- A standard heat pump exchanges heat with the outdoor air and brings it inside.
- A geothermal heat pump exchanges heat with the ground, where temperatures are more constant throughout the year.
- Electricity is only used to transfer heat, not to create it, meaning the unit is more efficient than other heating methods.
What to look for:
- The ENERGY STAR® label.
- The right size for your home.
- A reputable contractor to install your system.
Added benefits: Geothermal heat pumps tend to be quieter than conventional systems.
