When your furnace or air conditioner isn’t working the way it should, it doesn’t necessarily mean that it’s broken. Your thermostat could be the culprit. Before assuming that you’ll need HVAC repairs done, do some thermostat troubleshooting first. These are some common issues that can result from a faulty thermostat.
HVAC System Short-Cycles
If your HVAC system comes on and off frequently, this is known as short cycling. This can happen if your thermostat has dust or dirt inside it. Remove your thermostat and carefully clean off the components, then try running your HVAC system again. If your thermostat was to blame, it should run on longer cycles.
HVAC System Doesn’t Heat or Cool Efficiently
If your HVAC system doesn’t seem to reach the temperature you’ve set on your thermostat or if it goes beyond the set temperature, making sure your thermostat is properly mounted could fix the problem. Thermostats that are mounted crookedly aren’t showing you the actual temperature inside your home. Straightening out your thermostat should cause it to show the correct temperature.
HVAC System isn’t Heating or Cooling
If your HVAC system runs but doesn’t heat or cool your home, you could have a buildup of debris inside your thermostat. It might also have loose wires or a bad battery if you have a digital electronic type. You might also have a blown fuse that is affecting your thermostat. For thermostat troubleshooting in this case, check the fuse, clean the inside of your thermostat and check its wiring and battery to find out what’s causing the problem.
Check Thermostat Settings
If you suspect that your thermostat isn’t working right, you can check by setting it 5 degrees above or low your desired temperature. Your HVAC system should come on and be able to heat or cool your home to the set temperature.
