If your thermostat isn’t signaling your AC to work, it won’t turn on.
The first step is checking it’s set to “cool” and not “heat.” Otherwise your AC will probably not turn on. Or you might receive. hot air blowing from vents because the heater is on instead.
If you rely on a regular thermostat:
- Swap out the batteries if the monitor is blank. If the screen is displaying jumbled letters, buy a new thermostat.
- Make sure the proper option is displaying. If you can’t alter it, cancel it by dropping the temperature and pressing the “hold” button. This will force your AC to work if programming is wrong.
- Attempt to set the thermostat 5 degrees below the room’s temperature. Your AC won’t work if the thermostat is set the same as the house’s temperature.
Once your thermostat is calibrated accurately, you should receive refreshing air quickly.
If you have a smart thermostat, such as one made by Nest, Ecobee, Lux, Honeywell or Bosch, check the manufacturer’s website for help. If you’re still having problems, call us at 703-278-2036 for assistance.
