Geothermal heating and cooling may seem a bit like magic to homeowners—especially for homeowners who only recently found out that a geothermal HVAC system is a possibility for them and not something that’s out of reach. A geothermal heat pump has much greater energy efficiency than a standard air source heat pump, and it manages to pull off this trick through the simple concept of placing loops down in the ground rather than having the heat pump release and draw heat from the outside air.
What makes using the earth so much more efficient than the air? We’ll let you in on the secret in this post…
Although geothermal HVAC systems are becoming more common for homes, this technology is still new to many. Because of this, people often have misconceptions about how geothermal heating and cooling works and how useful it is. 
Geothermal heat pumps (a.k.a. a “ground-source” heat pumps) are becoming more common for residential homes. People who once thought that installing geothermal heating and cooling was out of their reach are finding that these installations are more flexible and affordable than ever before. If a home already has a standard AC or heat pump, most of the indoor work for installation is already done—a geothermal heat pump will use the same ductwork the current AC or heat pump uses. Putting in the ground loops isn’t as difficult as it may seem either.
