Wait, Do Geothermal Systems Work in the Summer Too?

Why, yes! They do! But, we understand why you might’ve believed otherwise — c’mon, the word “thermal” is right there in the name!

Geothermal systems, like all heat pumps, come equipped with a reversing valve, which allows for both home heating and cooling. That way, you can enjoy year-round comfort with just the flip of a switch. But even still, geothermal systems are different than their forced-air counterparts, and many homeowners don’t quite understand how they work.

So below, we’ve decided to explain the science of it all. Just keep reading below to find out more! (And of course, remember to schedule your HVAC services in Andover, MN with our team!)

So, How Do These Systems Keep Me Cool?

The indoor components of a geothermal heat pump are similar to those of a standard heat pump: a refrigerant coil where the refrigerant is either condensed or evaporated and a blower fan to send the conditioned air into the ventilation system. But where an air-source heat pump used an outdoor coil to perform heat exchange, a geothermal heat pump uses loops buried in the ground.

These loops are placed about 6–10 feet down into the earth, which gives them access to more stable temperatures. When the heat pump is in cooling mode, the refrigerant absorbs heat indoors, then transfers that heat into a water/anti-freeze mixture moving through the loops. The heat is then deposited into the ground, using it as a heat sink. The removal of heat from the house creates a nice cooling effect. In heating mode, the process reverses and heat is brought from the earth into the house.

Are There Benefits of Using a Geothermal System?

Why yes! There are plenty of benefits with using a geothermal system to cool your home during the summer. For one, these systems are super energy efficient. In fact, a geothermal heat pump works at 3-6 times greater energy efficient than an air source model, saving you hundreds of dollars on your annual utility bills! Secondly, these systems are super reliable, simply because the temperature of the earth does not fluctuate much at all. You can always be sure that your home will be nice and cool, even during the hottest heatwave! Lastly, these systems are super eco-friendly because they do not generate their own heat, but rather move it from one place to another.

You Need Professional Services

Not all homes are good candidates for geothermal systems, so it is important that you hire a professional who can determine if your home is a good fit. Installing one of these systems requires a lot of planning, so you want to be sure that you’ve got a team of professionals to guide you through the entire process. Trust us, when it comes to your comfort, you definitely do not want to take any risks!
