If your thermostat isn’t signaling your system to start, it won’t switch on.
The first part is making sure it’s on “cool” and not “heat.” Otherwise your AC might not turn on. Or you might receive. warm air moving from vents since the heater is going instead.
If you’re using a traditional thermostat:
- Put in new batteries if the monitor is clear. If the readout is showing garbled characters, replace the thermostat.
- Check the right option is on the display. If you can’t change it, override it by dropping the temperature and pushing the “hold” button. This will force your AC to work if programming is wrong.
- Try setting the thermostat 5 degrees cooler than the room’s temperature. Your AC won’t work if the thermostat is identical to the space’s temperature.
Once your thermostat is adjusted accurately, you should receive chilled air promptly.
If you have a smart thermostat, such as one made by Nest, Ecobee, Lux, Honeywell or Bosch, check the manufacturer’s website for troubleshooting. If you’re still having problems, reach us at 760-784-9034 for support.
