If your thermostat isn’t telling your air conditioner to start, it won’t turn on.
The main step is ensuring it’s on “cool” and not “heat.” Otherwise your AC may not turn on. Or you may have. hot air blowing from vents being the furnace is going instead.
If you have a traditional thermostat:
- Swap out the batteries if the readout is empty. If the monitor is showing jumbled numbers, get a new thermostat.
- Ensure the proper program is on the display. If you can’t change it, cancel it by dropping the temperature and pushing the “hold” button. This will cause your AC to run if programming is not right.
- Try setting the thermostat 5 degrees lower than the room’s temperature. Your AC won’t start if the thermostat is set the same as the room’s temperature.
Once your thermostat is set accurately, you should receive refreshing air quickly.
