How Geothermal Systems Cool Your Home

Friday, June 6th, 2014

Geothermal systems represent a viable alternative to more traditional heating and cooling systems, tapping into the ambient temperature of the earth itself to do its job. When you get down below about five or six feet, the temperature under the ground remains at a constant regardless of what the weather is like upstairs. Geothermal systems run a series of tubes under the earth and then pump some form of refrigerant (usually a mixture of water and antifreeze) through them to facilitate a heat exchange with the ground. Here in Atlanta, geothermal systems have proven quite popular, particularly on property with a lot of square footage. Here’s a quick breakdown of how geothermal systems cool your home.

It starts inside your home, where warm or hot refrigerant is pumped through the central system and into the coils beneath the ground. The temperature under the ground stays set at about 55 degrees or so, which means that the heat from the refrigerant bleeds into the ground as it passes through. By the time it completes its cycle and returns to the house, it’s usually the same temperature as the earth. That, in turn, pulls heat from the air in the in-house portion of the system, cooling it and allowing it to be dispersed through your home with a fan. The process warms the refrigerant up again, just in time to send it back into the coils and start the process anew.

This is very efficient because you’re not expending any energy to warm or cool the refrigerant. The earth is doing that for you, meaning you only need enough power to circulate the liquid and run the fan blowing the cool air into your home. As a result, geothermal systems cost much less to run month-to-month than more traditional forms of air conditioning, saving you a great deal of money in the process.

Atlanta Geothermal Guide: Types of Geothermal Loop Systems

Monday, March 4th, 2013

A geothermal heating and cooling system is a great home comfort option for those homeowners in Atlanta looking to reduce both energy costs and their environmental impact. Geothermal heating and cooling systems use a heat pump in order to keep your home comfortable year round in a very efficient, effective manner. In fact, geothermal systems are often more versatile and reliable than standard types of heat pumps.

This is due to the fact that they draw the heat they utilize from the ground or beneath water on your property, where temperatures are more constant. They are able to do this by using a geothermal loop system. Here is some information about the types of geothermal loop systems that may be used during your geothermal heating and cooling system installation. Call Air Conditioning experts for more information.

Closed Loop Systems

Most geothermal systems will use a closed loop system to circulate an antifreeze solution through the ground or in a body of water on your property. This solution is not used up or disposed of, but rather cycled throughout the closed loop system again and again. This type of loop system may be installed vertically or horizontally.

Horizontal installations are the most common type. They also require a certain amount of usable space on your property, though. Pipes are buried next to one another at staggered depths, and the antifreeze solution is piped through via the loop system, gathering heat. If there is not sufficient space the loops may be tightly coiled, allowing for an installation in smaller amounts of land. However, this runs the risk of overdrawing heat from the ground around the system

Open Loop Systems

In an open loop system water itself is used in place of an antifreeze solution. Once the cycle is completed the water is simply discharged from the system. Obviously this type of installation requires the availability of sufficient water on your property. A trained professional will help you determine if an open loop system is right for your home.

If you have any questions about geothermal heating and cooling system installations or the types of loop systems you may use, call Air Conditioning Experts. We are the geothermal professionals in the Atlanta area. Our technicians can help you heat and cool your home more efficiently and effectively with a geothermal heating and cooling system installation, so call today.

Is a Geothermal Heating and Cooling System Right for Your Atlanta Home?

Monday, February 11th, 2013

Geothermal heating and cooling technology has been around for quite some time, but as more and more homeowners look for affordable, environmentally friendly heating and cooling options it has grown more popular. Geothermal heating and cooling systems are a great home comfort option in Atlanta, but there are a number of factors to consider before deciding if one is right for your home. Contact Air Conditioning Experts today if you would like more information about geothermal heating and cooling systems. Here is some basic information to get you started.

In order to determine if a geothermal heating and cooling system installation is even possible on your property you must have an evaluation performed by a qualified expert. Geothermal systems use an underground loop system to keep your home comfortable. This loop system circulates an antifreeze solution or, in an open loop setup, water, to gather and transfer the heat necessary for operation. The loop system may be buried beneath the ground on your property or submerged in a body of water. Either way it is necessary that your property or the water on it meets certain size, quality and geological requirements. There is no way for you to be sure that a geothermal installation is a viable option for your home without the help of a professional.

It is also important that you consider your budget before making any decisions about the way in which you will heat and cool your Atlanta home. While geothermal heating and cooling systems incorporate a heat pump in order to keep your home comfortable efficiently, the installation process is more involved and expensive than that of an air-source heat pump. This initial investment can be offset over time with potential energy savings, though. Plus, due to the fact that the temperature beneath the ground or underwater is more constant than that of the air, geothermal systems are often more effective in a more diverse range of climates.

There is not any one heating and cooling system that is better than all the rest. With the help of a trained professional from Air Conditioning Experts, though, you can find the one that is best for your specific heating and cooling needs.
