Geothermal heat pumps are similar to conventional models. But instead of from the outdoor air, they transfer heat to and from the ground or water. Since ground and water temperatures stay more constant than air temperatures, geothermal units are more efficient. They can reduce your utility bills and increase the value of your home in Punta Gorda, Florida. They can also eliminate the need for an unsightly outdoor unit. Here are some of the most popular types of geothermal heat pumps available:

Closed Loop

Most geothermal HVAC systems circulate refrigerant or water through a closed loop of plastic or copper pipes. Along with a fan and ductwork, many closed loop systems use radiant heating. Pipes inside your walls or floors prevent cold floors and keep your family warm. They can also make getting out of bed or stepping out of the shower more pleasant.

Open Loop

Geothermal systems with open loops use water from a well or a nearby lake or pond. Water circulates between the pipes and the water source. Open loop systems with water filters can work as water heaters. Therefore, you’ll never have to worry about maintaining or replacing your current unit. Placing pipes underwater is less expensive than having holes dug for underground pipes, and you can get rid of your water bill by using a nearby water source.


Horizontal geothermal HVAC systems usually use closed loops. The pipes sit underground in horizontal trenches. Therefore, you’ll need a large yard that doesn’t have valuable landscaping to install this type of geothermal heat pump.


Vertical systems have pipes inside holes that are hundreds of feet deep and only a few inches wide. They won’t disturb your landscaping, but they’re more expensive to install. They work well in places with soil that’s mostly too hard or rocky for a horizontal system.
