If your thermostat isn’t giving a sign to your system to start, it won’t activate.
The most important part is checking it’s set to “cool” and not “heat.” Otherwise your air conditioner may not start running. Or you might get. warm air moving from vents being the furnace is going instead.
If you’re using a digital thermostat:
- Put in new batteries if the monitor is blank. If the screen is showing garbled letters, get a new thermostat.
- Ensure the proper setting is on the display. If you can’t update it, cancel it by decreasing the temperature and pressing the “hold” button. This will cause your AC to run if the configuration is incorrect.
- Try setting the thermostat 5 degrees lower than the house’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 chilled air quickly.
