If your thermostat isn’t giving a sign to your system to work, it won’t switch on.
The key point is making sure it’s switched to “cool” and not “heat.” Otherwise your AC may not switch on. Or you might receive. hot air coming from vents being the heater is going instead.
If you’re using a digital thermostat:
- Replace the batteries if the screen is blank. If the screen is presenting scrambled numbers, get a new thermostat.
- Check the right setting is on the display. If you can’t change it, reverse it by lowering the temperature and pushing the “hold” button. This will cause your AC to run if the configuration is not right.
- Attempt to set the thermostat 5 degrees colder than the space’s temperature. Your AC won’t cool if the thermostat matches the room’s temperature.
Once your thermostat is set correctly, you should receive chilled air fast.
