Do Geothermal Systems Work in the Summer?

Tuesday, May 28th, 2019

When homeowners hear the word geothermal, they often think of heat. Obviously, this makes sense as the word thermal is right there in the name! And indeed, geothermal heat pumps are an excellent way to keep your home warm all winter long. But, what about the summer?

Geothermal heat pumps, like all heat pumps, offer cooling as well! So, if you are currently in the market for a new way to keep your home cool this summer, don’t count out geothermal systems as an option! Below, we will explain how geothermal systems work and some of the reasons why you should consider installing this type of system. Keep reading to find out more!

Geothermal Question: How Do Geothermal Systems Work?

Monday, January 14th, 2013

Geothermal systems are specifically designed to take full advantage of all of the energy stored under the ground. There seems to be a lot of confusion in Rincon around about how exactly geothermal systems work. We thought it would be helpful for our customers if we put together a quick explanation. Below are some of the main components in geothermal systems and how they work together.

The Sun and the Earth

As the sun beats down on the earth every day, that energy gets stored in the ground. If you were to dig down about 10 feet into the ground, the temperature there would be about 55° F—and it stays that way all year long. No matter what the temperature of the air is above, the ground is consistently the same temperature. Geothermal systems take advantage of that consistency to heat and cool your home.

Underground Loop

The way that geothermal systems are able to harness the energy in the ground is through a series of buried pipes. The pipes can be laid out horizontally if your property has the space for them. They can also be installed vertically in deep holes drilled out of the ground. The pipes are basically one big loop that is connected to a heat pump in your home. The refrigerant enters the heat pump and is then returned out into the ground.

The Refrigerant

After the pipes are buried in the ground, a refrigerant is pumped through them. This refrigerant is very sensitive to heat and is an environmentally friendly version of other refrigerants like Freon. The refrigerant’s job is to carry heat. A pump is used to move the refrigerant through the pipes.

The Heat Pump

At the heart of a geothermal system is the heat pump. The heat pump is what actually heats and cools your home using an evaporator coil in the air handler. Here’s how it works: in heating mode, the refrigerant will extract heat out of the ground. The heated refrigerant is pumped into the heat pump and through the evaporator coils. A fan blows air over the coils. The newly heated air is then distributed to your home via your ductwork. In cooling mode, the opposite occurs.

Geothermal FAQ’s

Monday, December 17th, 2012

With professional installation and regular maintenance service a geothermal heating and cooling system can provide you with decades of efficient, effective comfort. A lot of people know next to nothing about the installation and operation of these incredible systems, though, so AAction Air has gathered some information for your consideration. We hope you find this information helpful, and if you have any further questions contact us to speak with a Savannah geothermal heating and cooling expert on our staff.

  • What is the installation cost of a geothermal system?

The cost of installing a geothermal system varies due to a number of factors. The option of an open or closed loop system, the potential need for geothermal drilling, heating distribution style, and property-specific considerations all inform the cost of a geothermal installation. Generally these systems are more expensive to have installed than conventional heating systems, but the operational cost savings can recoup that over time.

  • What type of loop system do I need?

This is also contingent on the specifics of your property and the area in which you live. In colder climates such as the northeast a vertical system may be the best option. Have your land assessed by a professional for a concrete answer.

  • What benefits do geothermal systems offer?

Geothermal systems use existing heat to warm your home, drastically reducing the amount of energy you use to maintain comfort. The process is easily reversed to cool your home, and thanks to the depth at which the loop system is buried they are less susceptible to temperature fluctuation problems than air source heat pumps.

If geothermal energy sounds like an option that you’re interested in, please contact us at AAction Air with any questions you have. We believe that consumers should be informed and are happy to provide any information you need to make the right decision for your home. If you decide to go ahead with a geothermal system installation in Savannah, let us know.
