If your thermostat isn’t signaling your system to run, it won’t activate.
The key part is making sure it’s switched to “cool” and not “heat.” Otherwise your air conditioner will probably not turn on. Or you might receive. warm air coming from vents since the furnace is going instead.
If you rely on a traditional thermostat:
- Replace the batteries if the readout is clear. If the monitor is showing garbled letters, get a new thermostat.
- Ensure the right program is showing. If you can’t alter it, reverse it by lowering the temperature and pressing the “hold” button. This will force your AC to work if the configuration is not right.
- Test setting the thermostat 5 degrees cooler than the room’s temperature. Your AC won’t cool if the thermostat matches the space’s temperature.
Once your thermostat is set accurately, you should start getting chilled air quickly.
