If your geothermal system isn’t running, there’s a good chance that you’ll want to seek professional help. Before that happens, though, there are some things to look out for, and possibly even a fix or two that you can try.

What you can try

Here are some things you should check in the event that your geothermal system isn’t running:

  • Thermostat settings – It’s possible that either the system simply isn’t switched to “auto”or “heat.” A second possibility is that it isn’t set any lower or higher than the room’s current temperature. To test the system, switch the temperature to its lowest or highest point, and see if the HVAC system kicks on.
  • Air filter – If your geothermal system is working, but the air flow coming from the registers seems to be low, it’s possible that you have a clogged air filter. This is simple to check and fix, if that’s the case.
  • Registers – Be sure that the registers are open. If anything is obstructing them, be sure to move the blocking item.
  • Fuse/breaker – This is another possibility. Perhaps the breaker was tripped. This is another easy fix if that’s the problem.
  • Power disconnect switch – Be sure you check both the indoor and outdoor units to make sure this switch hasn’t been tripped.

Nothing beats a service call

The above details are some of the things you can check when your geothermal system isn’t running. However, it’s important to remember that a service call will guarantee results. A professional HVAC technician can evaluate your system and make sure that it’s operating at peak performance. In fact, even if you don’t have any problems with your geothermal system, it’s always good to have it checked on a regular basis.
