If your thermostat isn’t telling your AC to work, it won’t activate.
The main step is making sure it’s set to “cool” and not “heat.” Otherwise your AC will probably not switch on. Or you could have. warm air coming from vents being the heater is going instead.
If you rely on a digital thermostat:
- Swap out the batteries if the screen is clear. If the monitor is presenting jumbled characters, buy a new thermostat.
- Ensure the correct mode is showing. If you can’t alter it, reverse it by decreasing the temperature and pushing the “hold” button. This will make your AC start if the configuration is incorrect.
- Attempt to set the thermostat 5 degrees below the room’s temperature. Your AC won’t start if the thermostat is identical to the space’s temperature.
Once your thermostat is set properly, you should start getting chilled air fast.
