If your thermostat isn’t signaling your equipment to work, it won’t activate.
The key part is making sure it’s set to “cool” and not “heat.” Otherwise your air conditioning will probably not turn on. Or you could have. warm air coming from vents because the heater is going instead.
If you’re using a traditional thermostat:
- Put in new batteries if the monitor is empty. If the readout is displaying jumbled letters, get a new thermostat.
- Check the right option is on the display. If you can’t update it, reverse it by decreasing the temperature and pressing the “hold” button. This will force your AC to work if scheduling is wrong.
- Attempt to set the thermostat 5 degrees below the space’s temperature. Your AC won’t cool if the thermostat matches the room’s temperature.
Once your thermostat is adjusted correctly, you should begin getting cool air quickly.
If you have a smart thermostat, like one produced by Nest, Ecobee, Lux, Honeywell or Bosch, go to the manufacturer’s website for help. If you’re still having problems, contact us at 203-357-5913 for help.
