If your thermostat isn’t giving a sign to your air conditioner to start, it won’t switch on.
The first point is checking it’s on “cool” and not “heat.” Otherwise your AC may not turn on. Or you could have. hot air moving from vents being the furnace is going instead.
If you’re using a digital thermostat:
- Replace the batteries if the screen is clear. If the screen is showing scrambled letters, buy a new thermostat.
- Ensure the proper program is showing. If you can’t change it, reverse it by dropping the temperature and hitting the “hold” button. This will make your AC start if scheduling is incorrect.
- Test setting the thermostat 5 degrees lower than the house’s temperature. Your AC won’t cool if the thermostat is identical to the space’s temperature.
Once your thermostat is calibrated accurately, you should start getting refreshing air quickly.
