Stable underground temperatures
The earth below the surface remains far more consistent than the outdoor air.
Why geothermal works differently
Comfort that does not depend on the temperature outside
Traditional air-conditioning systems release heat into the outdoor air. As outdoor temperatures rise, those systems may have to work harder to maintain indoor comfort.
Geothermal systems exchange heat with the more stable temperatures beneath the ground, helping to provide efficient and consistent cooling even during periods of extreme heat.
Less strain during peak heat
Geothermal systems do not rely on extremely hot outdoor air to reject heat from the home.
Consistent indoor comfort
A properly designed system can help maintain steady cooling through the hottest parts of summer.
