What You Need to Know to Maintain Your Geothermal System

Geothermal HVAC systems deliver heating and cooling through ground loops buried deep in your soil where the ground temperature is constant year-round. This delivers you with an abundant source of energy in the winter and a heat sink in the summer, but it also places the outdoor coils out of reach. Fortunately, geothermal systems are most reliable, and maintaining one is easy for homeowners even when the ground loops aren’t accessible.

Check out a few tips on maintaining a geothermal system:

  • Use the correct thermostat. A wired rather than battery-driven thermostat is always a wise choice, and using a programmable thermostat to run the geothermal system when only necessary will increase your energy efficiency. Make sure the thermostat is also set correctly, and that the fan is set to “auto,” not “on.”
  • Change the air filter monthly and if you want more air filtration, consider a whole-house air cleaner.
  • Consistently check the condensation pans for standing water, and clear the drain of any blockage. Every year, rinse the drain using a dilute bleach solution to keep it flowing freely.
  • Do not close the vents in your home, and watch them for any debris or blockage. Make sure not to position furniture or clutter in front of the vents.
  • Review your ductwork and repair any leaks. Leaks may be visible as punctures, gaps and tears or they may be a pattern of blown-out dust on the ceiling or wall next to the duct.
  • Review your owner’s manual and be sure to make yourself familiar with the various indicator lights and system accessories.
  • Schedule seasonal maintenance with your local geothermal experts. They should be able to conduct a thorough inspection, including a check of the refrigerant levels, a check of electrical connections and also any maintenance of your internal components.
