If your thermostat isn’t telling your AC to run, it won’t turn on.
The first step is making sure it’s switched to “cool” and not “heat.” Otherwise your air conditioning may not turn on. Or you may get. warm air moving from vents since the furnace is running instead.
If you have a regular thermostat:
- Put in new batteries if the monitor is clear. If the monitor is displaying jumbled numbers, buy a new thermostat.
- Make sure the right option is on the display. If you can’t change it, cancel it by lowering the temperature and hitting the “hold” button. This will make your AC start if the configuration is not right.
- Try setting the thermostat 5 degrees colder than 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 set properly, you should start getting 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 help. If you’re still having problems, contact us at 715-318-6728 for assistance.
