Repair Issues for Geothermal Systems

Monday, April 11th, 2016

Geothermal heat pumps and similar systems make a lot of sense in our part of the world. The ambient heat beneath the ground doesn’t change once you get more than a few feet below the surface. Geothermal systems make cunning use of that, installing tubes below the surface the circulate a mixture of water and antifreeze. That lets them pull heat from the earth or deposit heat into the earth from your home: providing reliable heating and cooling for very little money. They usually require large stretches of property, but that’s not a problem here in Selma, TX, and installation options are available for properties with smaller square footage. Problems are rare for geothermal systems – it’s one of the benefits of this particular form of cooling – but they do happen, and when they do, you want the right service to come make it right. Here’s a quick list of a few to keep an eye out for.

Principles Behind Geothermal Cooling

Friday, June 27th, 2014

The power to cool your home can come from right beneath your feet: the heat of the earth provides a renewable, efficient, and clean source of energy that you can harness with a geothermal heat pump. Like any heat pump, a geothermal model can provide you with both heating and cooling, whatever your needs during the year.

If you would like to take advantage of the many benefits of a geothermal heat pump, contact our staff today to get started.

At Cowboys Air Conditioning & Heating, we offer comprehensive service for installation, repair, and maintenance when it comes to geothermal cooling in San Antonio, TX.

How geothermal cooling works

The basic principle behind cooling with a geothermal heat pump is the same as that of a regular (or “air-source”) heat pump. The heat pump circulates refrigerant through the system, absorbing heat in one location, and then releasing it in another. When in cooling mode, the heat pump’s refrigerant absorbs heat from the inside of a house, and then removes it from the house to release it. Heating mode reverses the direction, and the refrigerant releases the heat into the house. This process is called heat exchange.

But where the geothermal system differs is that it uses a different medium for heat exchange than a standard heat pump. Instead of using the air for both absorption and release of heat, a geothermal heat pump uses the earth for half of the process, which is why geothermal systems are sometimes called “ground-source” heat pumps.

The outside section of a geothermal heat pump isn’t an outdoor coil, but a set of plastic loops buried at least 10 feet into the ground. The refrigerant in the system (water or a solution of water and anti-freeze) runs through these coils to absorb or release heat. In heating mode, the loops draw heat from the ground, and in cooling they deposit heat into the ground.

Because the earth 10 feet below the surface maintains a steady temperature of approximately 55°F, the heat pump always has a reliable source for the exchange. No matter how hot it is outside, the system has a cooler location to release the heat removed to cool the indoors. No matter how cold it is outside, the system has a warmer location to draw heat to warm the indoors. This makes geothermal systems both reliable and energy efficient.
