If your thermostat isn’t telling your AC to start, it won’t switch on.
The main part is making sure it’s switched to “cool” and not “heat.” Otherwise your air conditioning will probably not turn on. Or you might get. hot air blowing from vents since the heat is going instead.
If you rely on a digital thermostat:
- Replace the batteries if the screen is blank. If the readout is showing garbled numbers, replace the thermostat.
- Check the proper program is displaying. If you can’t update it, reverse it by decreasing the temperature and pressing the “hold” button. This will cause your AC to run if the configuration is incorrect.
- Test setting the thermostat 5 degrees below the space’s temperature. Your AC won’t start if the thermostat is identical to the space’s temperature.
Once your thermostat is adjusted properly, you should receive cold air quickly.
