A functioning thermostat is central to an efficient HVAC system and a comfortable home. As a consequence, homeowners should learn to recognize when their thermostat is defective. Here are some signs of a faulty thermostat. 

Is Your Thermostat Acting Up? Look for These Signs

1. The Thermostat Is Glitchy

If your thermostat has an electronic display screen, it’s usually clear when it’s not working correctly. The up and down buttons may be unresponsive, or the screen may be blank. If the display lighting seems blurry or faded, a contractor should inspect the wiring and replace the thermostat if needed.

2. The Temperature Stays the Same

Your thermostat may be faulty if the temperature doesn’t go up or down when you adjust the settings. Try moving the thermostat up or down by five degrees. You should feel a temperature change after your HVAC system has been running for several minutes. If you don’t, call a heating and cooling repair company to check the status of your device.

3. The Temperature Is Inaccurate

If the temperature of your home doesn’t seem to match the setting on the thermostat—if it’s set to 72 degrees but feels like 65—the device may be defective. A well-functioning thermostat should be accurate. Test it by placing an indoor thermometer in the center of a room, noting whether its temperature aligns with that on your wall unit. A heating and cooling contractor will advise you if your thermostat or your HVAC system requires repair or replacement.
