Geothermal Heating System Repair

Learn basic geothermal heating repair from Trane. We’ll walk you through DIY geothermal repair, and provide guidance on when to call the professionals.

Geothermal heating uses heat stored below ground to power your heating and cooling systems. The system includes a heat pump connected to an energy source under the ground (usually about four to six feet deep) connected to an indoor air handling unit. The indoor unit then moves the heated or cooled air throughout your home.

Like traditional HVAC systems, geothermal heat systems may encounter occasional maintenance problems that require troubleshooting. For most repairs, a trained professional should be consulted, so you’ll need to contact your local Trane Comfort Specialist. There are, however, a few basic checks you can perform yourself.

DIY Geothermal repair basics

Before calling a professional, you can perform these basic checks on your geothermal heating system.

• Check to make sure the unit is plugged in and receiving power
• Look for a blown fuse or a tripped circuit breaker
• Make sure the thermostat is set to the correct temperature and turned to the correct mode (either heating or cooling).
• Check the air filter and coils. Change the filter and clean the coils if needed, which could be preventing air flow.

Professional geothermal heating repair

Beyond these basic concerns, it’s best to call a Trane Comfort Specialist who can perform a technical diagnosis of our system and perform any needed repairs. Potential problems could include leaks, broken wiring, loop system issues, low refrigerant, defective reversing valve and more.

Regular maintenance

To extend the life of your system, regular checkups are advised. This will include cleaning filters, coils and condensate traps. For the advised maintenance timeline, consult your owner’s manual and schedule appointments with your local Trane Comfort Specialist as needed.
