No Heat From Your Geothermal System? Troubleshoot These 3 Things Before Calling A Technician

Winter winds are howling outside your door. As you step out of your warm bed, you realize that the air inside your home isn't as warm as it should be. Clearly, something has gone wrong with your geothermal heating system. Before you let panic take over, it's important to realize that the lack of heat doesn't necessarily mean that your geothermal system has suffered a catastrophic failure. In fact, the problem with your system may only require some simple troubleshooting. So, before you call in the HVAC repair technician, check these common causes of heating failure first.

Loss of Power

Without a power supply, your geothermal system will not run. One very common reason for the loss of power to your system is a tripped breaker. A breaker that has tripped has flipped into safe mode, cutting off the power supply to all appliances plugged into a particular circuit.

To see if a tripped breaker is your problem, go to your breaker box and locate the breaker that supplies power to your system. Flip the breaker back into the on position. Your heating system should now have power. If the breaker trips again, you'll need to have an electrician inspect your electrical system for problems.

Dirty Air Filter

The air filter on your heating system should be changed approximately every 90 days. If you haven't been keeping up with your filter changes, this may be the reason why your geothermal system isn't working well.

The air filter prevents dust and debris from entering your heating system by trapping them on its screen-like surface. When the air filter becomes clogged, air can't circulate over your system's coils. This results in overheating. To prevent system damage, your geothermal system will shut off. Replace the dirty filter with a clean one and turn your heating system back on.

Incorrect Thermostat Setting

Your thermostat controls your heating system. So, if it isn't set properly, your home may feel colder than it should. To see if you're thermostat is set properly, ensure that

  • it is set to heat and not cool
  • fan is on auto
  • set temperature is not lower than the temperature inside your home

The temperature setting of your thermostat is very important. Remember your geothermal system will only heat your home to the temperature you've set. However, if the air inside your home is registering at 65 degrees, and your thermostat is set to 60, your system won't run. So if you're chilly, you'll need to set your thermostat above 65 for the heat to turn on and warm up your home.
