Is Geothermal Heating and Cooling an Option for Your Home?

Monday, November 9th, 2015

It’s one of the most efficient heating and cooling systems on the market today, and yet, few homeowners ever consider geothermal heating and cooling systems when it’s time to install a new unit. Geothermal installation involves putting a large, intricate loop system in the ground, which means digging up your property and a lot of time for the installation process. But once installed, geothermal systems are highly efficient and last many years. Before you can decide whether it’s right for you, however, you’ll have to ask yourself some questions.

What Kind of Repairs Should I Expect for a Geothermal System?

Monday, March 10th, 2014

One of the major advantages of having installation of a geothermal heat pump in your home is the incredible longevity of these systems. According to the U.S. Department of Energy, the indoor elements of a geothermal system can last 20+ years, while the in-ground coils (the most expensive part of installation) can last 50+ years. That’s an enormous amount of time for you to get the full benefits of the energy-efficient performance of geothermal power.

However, durability doesn’t mean invincibility, so you can expect occasional repair needs for your ground source heat pump. Here are some repairs you might encounter from your system. Call on experts in geothermal repair in Pooler, GA when you need assistance: look to AAction Air, where our technicians are on-call 24-hours a day.

Some geothermal repair needs you might have

  • Leaks in the pipes: The underground pipes that run through your property, carrying the crucial water and antifreeze mixture needed for heat exchange, rarely develop leaks (unless they were poorly installed). But accidents from extreme weather conditions, construction, or age can still lead to leaking, and this will cause your indoor heat pump to lose efficiency. A technician can put a dye into your system and then trace where it emerges on the surface to find leaks. This allows the least amount of excavating necessary for repairs.
  • Broken reversing valve: If your ground source heat pump seems to only provide heat when need cooling, or vice versa, the problem could be refrigerant leaking… but it could also be a failed reversing valve, which means the refrigerant going through the heat pump will only go one direction and therefore you cannot switch between modes. Thankfully, this repair requires no digging: the technician needs only open up your indoor unit and replace the broken reversing valve.
  • Replacing the indoor heat pump: We mentioned above that the indoor unit has a lower life-expectancy than the in-ground elements. Normally, “replacing the heat pump” for an air-source heat pump wouldn’t count as a repair, it would be a full new heat pump installation. With geothermal, however, the underground coils will remain in place, and the unit that contains the air handler, compressor, and reversing valve is replaced if it has worn down too much. You can expect this repair to happen eventually—but with proper annual maintenance it should be many years off.

Make sure you take excellent care of your geothermal heat pump so that the repairs you do need will be few and far between. When it is time for geothermal repair in Pooler, GA, contact our experts at AAction Air.

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.
