If your thermostat isn’t signaling your system to start, it won’t turn on.
The first step is making sure it’s on “cool” and not “heat.” Otherwise your AC may not turn on. Or you may receive. hot air coming from vents because the heater is running instead.
If you’re using a traditional thermostat:
- Swap out the batteries if the screen is blank. If the monitor is displaying scrambled numbers, buy a new thermostat.
- Ensure the proper program is displaying. If you can’t update it, cancel it by lowering the temperature and pushing the “hold” button. This will force your AC to work if programming is incorrect.
- Attempt to set the thermostat 5 degrees below the house’s temperature. Your AC won’t start if the thermostat is set the same as the house’s temperature.
Once your thermostat is adjusted properly, you should receive chilled air promptly.
