If your thermostat isn’t signaling your system to start, it won’t activate.
The main step is making sure it’s set to “cool” and not “heat.” Otherwise your air conditioning may not start running. Or you may have. heated air moving from vents since the heater is running instead.
If you’re using a regular thermostat:
- Swap out the batteries if the monitor is blank. If the monitor is presenting garbled characters, get a new thermostat.
- Ensure the proper mode is displaying. If you can’t change it, reverse it by decreasing the temperature and pressing the “hold” button. This will cause your AC to run if programming is wrong.
- Test setting the thermostat 5 degrees below the house’s temperature. Your AC won’t cool if the thermostat matches the room’s temperature.
Once your thermostat is set accurately, you should begin getting cool air fast.
