Thermostat Repairs & Troubleshooting

Over time, thermostats can lose calibration, send faulty signals, and cause a variety of heating and air conditioning problems. Your thermostat is more than just a means for controlling your HVAC system—it should work seamlessly with your unit to adjust room temperature and maintain comfort. When your thermostat has dirty components, gets knocked out of calibration, or breaks completely, you lose system performance and efficiency.


Troubleshooting Your Thermostat


Modern electronic thermostats are sealed at the factory, reducing the need for cleaning and adjusting. However, old and new thermostats can require occasional maintenance, recalibration, and repair. If your thermostat doesn’t seem to be working, you can try to troubleshoot it on your own before calling a professional.


  • Double check your circuit breaker to ensure a fuse hasn’t blown.


  • Try replacing the battery if you have a digital thermostat.


  • Feel for cold or warm air coming through the wall. This could mean your thermostat requires caulking or insulation.


If you think your thermostat requires cleaning, call a professional HVAC technician to do this for you. Even if you can remove the cover yourself and see dusty parts, it’s safer to leave cleaning to the professionals. Electronic components of a thermostat are delicate and require the expert care of a trained technician. If you can’t solve your thermostat problem with an at-home fix, trust Palm Harbor Heating & Air Conditioning to perform a repair or replacement.
