If your thermostat isn’t signaling your equipment to run, it won’t activate.
The main step is checking it’s switched to “cool” and not “heat.” Otherwise your air conditioner might not turn on. Or you could have. hot air coming from vents because the heater is going instead.
If you have a digital thermostat:
- Put in new batteries if the screen is blank. If the screen is showing jumbled numbers, replace the thermostat.
- Make sure the right setting is displaying. If you can’t alter it, cancel it by decreasing the temperature and pressing the “hold” button. This will force your AC to work if scheduling is not right.
- Try setting the thermostat 5 degrees below the house’s temperature. Your AC won’t start if the thermostat is set the same as the house’s temperature.
Once your thermostat is adjusted correctly, you should begin getting chilled air fast.
