At Sunset Heating and Cooling we recommend the auto setting because it's the most efficient setting. That way, the fan operates only when the temperature requires it. Having it on the auto setting will also save you more energy.

Some thermostats require Battery’s. If your thermostat is blank you should change them. If your thermostat does not take battery’s call us at 949-302-3473 for service.
