3 Common Repairs for Geothermal Systems

Geothermal heating systems consist of a heat pump and pipes below the ground on your property, which draw upon the ambient temperatures of the earth itself to warm your home. Below the ground, the earth’s temperature doesn’t change, and that constant allows tubes full of liquid to facilitate a heat exchange and warm your home with it. Geothermal systems require a certain amount of land space, but they’re inexpensive to run and can save you a great deal of money on monthly heating costs. However, even though they are very reliable systems, you might occasionally need to schedule repairs with a reliable Frederick, MD heating contractor. Below are some common geothermal repairs:

  • Leaks: Leaks rarely happen within the tubing itself, since it’s underground and thus protected from most forms of damage. Refrigerant leaks in the heat pump inside your home are more common, however, and can severely restrict the efficiency of your unit. Sometimes, you will be able to see signs of the refrigerant leak, but more often, the signs will be more subtle: usually with higher energy bills signaling the system’s lost effectiveness.
  • Air Flow Problems: Just like with an air source heat pump, proper air flow speed is essential to effective heating. Air flow that is too fast will lead to inadequate heating, and air flow that is too slow will lead to hot and cold spots throughout your home. Your technician can check the air flow during your annual maintenance visit.
  • Thermostat Issues: As with any heating system, an inaccurate or malfunctioning thermostat can cause issues with your geothermal system. Make sure that your thermostat is set to “heat” and that it is turned up high enough to trigger your system. If those two things are not the issue, call a professional to take a look at your thermostat.
