If your thermostat isn’t signaling your AC to work, it won’t switch on.
The main step is ensuring it’s set to “cool” and not “heat.” Otherwise your AC may not start running. Or you may get. hot air blowing from vents since the heat is on instead.
If you’re using a digital thermostat:
- Swap out the batteries if the screen is empty. If the monitor is presenting scrambled numbers, buy a new thermostat.
- Make sure the right setting is showing. If you can’t change it, override it by lowering the temperature and hitting the “hold” button. This will cause your AC to run if programming is not right.
- Attempt to set the thermostat 5 degrees lower than the house’s temperature. Your AC won’t work if the thermostat is set the same as the space’s temperature.
Once your thermostat is calibrated properly, you should begin getting cool air fast.
