If your thermostat isn’t signaling your system to work, it won’t turn on.
The key point is checking it’s on “cool” and not “heat.” Otherwise your air conditioner may not start running. Or you may get. heated air blowing from vents being the heat is on instead.
If you’re using a regular thermostat:
- Put in new batteries if the readout is empty. If the readout is showing scrambled letters, replace the thermostat.
- Make sure the proper option is displaying. If you can’t update it, cancel it by decreasing the temperature and hitting the “hold” button. This will cause your AC to run if the configuration is not right.
- Try setting the thermostat 5 degrees lower than the room’s temperature. Your AC won’t start if the thermostat is identical to the house’s temperature.
Once your thermostat is adjusted accurately, you should receive refreshing air quickly.
