If your thermostat isn’t telling your system to run, it won’t switch on.
The first part is ensuring it’s set to “cool” and not “heat.” Otherwise your AC may not start running. Or you could get. hot air moving from vents because the heat is on instead.
If you have a digital thermostat:
- Swap out the batteries if the readout is blank. If the readout is showing jumbled numbers, replace the thermostat.
- Check the correct option is displaying. If you can’t update it, reverse it by dropping the temperature and pressing the “hold” button. This will force your AC to work if programming is incorrect.
- Attempt to set the thermostat 5 degrees below the space’s temperature. Your AC won’t cool if the thermostat is identical to the room’s temperature.
Once your thermostat is adjusted properly, you should receive cold air fast.
If you rely on a smart thermostat, like one made by Nest, Ecobee, Lux, Honeywell or Bosch, look at the manufacturer’s website for troubleshooting. If it still won’t work, contact us at 631-460-5159 for assistance.
