If your thermostat isn’t telling your equipment to start, it won’t turn on.
The main part is checking it’s set to “cool” and not “heat.” Otherwise your AC might not switch on. Or you might receive. heated air blowing from vents being the heat is on instead.
If you’re using a traditional thermostat:
- Replace the batteries if the monitor is blank. If the screen is displaying jumbled numbers, buy a new thermostat.
- Ensure the proper mode is showing. If you can’t change it, override it by lowering the temperature and pushing the “hold” button. This will force your AC to work if programming is not right.
- Try setting the thermostat 5 degrees below the room’s temperature. Your AC won’t work if the thermostat is identical to the room’s temperature.
Once your thermostat is calibrated correctly, you should start getting cold air promptly.
