If your thermostat isn’t giving a sign to your system to start, it won’t activate.
The most important point is making sure it’s switched to “cool” and not “heat.” Otherwise your AC will probably not switch on. Or you could receive. hot air blowing from vents being the furnace is on instead.
If you have a regular thermostat:
- Replace the batteries if the screen is blank. If the readout is presenting jumbled numbers, get a new thermostat.
- Make sure the right program is showing. If you can’t change it, reverse it by dropping the temperature and pressing the “hold” button. This will force your AC to work if the configuration is incorrect.
- Try setting the thermostat 5 degrees colder than the house’s temperature. Your AC won’t start if the thermostat is identical to the space’s temperature.
Once your thermostat is calibrated accurately, you should start getting cool air quickly.
