Geothermal cooling and heating systems are a truly remarkable way to condition the air in your home. They rely on the temperature under the ground – which stays constant once you get more than a few feet deep no matter what the temperature outside is – to facilitate a heat exchange. Coiled tubes under the earth circulate a mixture of water and anti-freeze, which either release heat from your home into the ground, or pull heat from the ground to warm your home. They’re energy efficient and extremely long-lasting, but like any appliance, they run into problems from time to time. The good news is that services offering air conditioning repair in Hartford, CT and similar towns can often handle common repairs for geothermal systems as well.
The good news is that the majority of problems take place above ground. The tubes have no moving parts and are protected from erosion by the earth. (The bad news is that, in the unlikely event of a breach, you’ll need to excavate the tubes to get them fixed, which can cost quite a bit.) The most common issues occur in the above-ground portion: the pump that circulates the fluids and the mechanisms that push the heated or cooled air through your home. In the event of a pump malfunction, the fluid will circulate more slowly and you won’t get the hot or cool air that you need. Similarly, a problem with the fan or fan motor will keep the conditioned air from circulating, and clogs in various lines may prevent any aspect of the system from functioning.
You can usually spot the need for common repairs for geothermal systems by a general slowdown in your system’s quality: lower air flow, reduced heating or cooling capacity, a sudden spike in monthly energy costs, and so on. When that happens you need to call on a company that can make repairs quickly, and for air conditioning repair in Hartford, CT the experts at Dynamic Mechanical Heating & Air Conditioning are ready to help.
