If your thermostat isn’t telling your equipment to start, it won’t switch on.
The most important part is ensuring it’s on “cool” and not “heat.” Otherwise your AC will probably not turn on. Or you could have. hot air moving from vents being the heat is running instead.
If you rely on a traditional thermostat:
- Swap out the batteries if the monitor is clear. If the monitor is presenting scrambled letters, buy a new thermostat.
- Ensure the correct mode is showing. If you can’t update it, override it by decreasing the temperature and hitting the “hold” button. This will force your AC to work if programming is wrong.
- Attempt to set the thermostat 5 degrees colder than the house’s temperature. Your AC won’t cool if the thermostat matches the room’s temperature.
Once your thermostat is calibrated accurately, you should receive refreshing air quickly.
If you rely on a smart thermostat, including ones produced by Nest, Ecobee, Lux, Honeywell or Bosch, check the manufacturer’s website for help. If you’re still having problems, call us at 717-479-4950 for assistance.
