If your thermostat isn’t telling your AC to run, it won’t activate.
The key step is making sure it’s set to “cool” and not “heat.” Otherwise your air conditioning may not switch on. Or you might receive. warm air blowing from vents being the heat is on instead.
If you rely on a traditional thermostat:
- Replace the batteries if the monitor is empty. If the monitor is showing garbled characters, replace the thermostat.
- Ensure the correct setting is on the display. If you can’t alter it, override it by decreasing the temperature and hitting the “hold” button. This will make your AC start if programming is not right.
- Test setting the thermostat 5 degrees colder than the room’s temperature. Your AC won’t cool if the thermostat matches the room’s temperature.
Once your thermostat is adjusted accurately, you should begin getting cool air promptly.
