If your thermostat isn’t signaling your air conditioner to work, it won’t activate.
The key part is ensuring it’s switched to “cool” and not “heat.” Otherwise your air conditioner may not turn on. Or you might have. hot air blowing from vents since the heater is running instead.
If you’re using a regular thermostat:
- Put in new batteries if the monitor is blank. If the screen is presenting jumbled characters, get a new thermostat.
- Check the proper mode is displaying. If you can’t update it, override it by decreasing the temperature and pressing the “hold” button. This will make your AC start if programming is incorrect.
- Test setting the thermostat 5 degrees colder than the space’s temperature. Your AC won’t start if the thermostat is set the same as the space’s temperature.
Once your thermostat is set accurately, you should receive cold air promptly.
If you have a smart thermostat, including ones manufactured by Nest, Ecobee, Lux, Honeywell or Bosch, check the manufacturer’s website for troubleshooting. If you’re still having problems, contact us at 507-387-6596 for support.
