Repair Issues for Geothermal Systems

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.

  • Low Heat or Cool Levels. If the system isn’t generating sufficient heat of cooling levels, it’s often a problem with the liquid flowing through the tubs, which can be traced to a pump issue or perhaps a clog in the line. A trained technician can usually take care of both.
  • No Cooling at All. Refrigerant can sometimes leak from the system as it can from a regular air conditioning. Plugging the leak and recharging the refrigerant should solve the problem.
  • High Humidity. In cases where the humidity is too high, the fan motor may be overpowered, causing excessive air flow within the system. A technician can adjust the motor or replace it with one that is appropriately sized.
  • Electrical Issues. Heat pumps rely on electricity to run the pump and fan motor. Frayed wires or other problems may cause those components to malfunction.
