How do I fix my commercial hvac?

Answer 1

The first thing you need to do is to change your thermostat setting from COOL to FAN. Then, you need to address the main cause of the problem. First, you need to know that if the temperature in your location dips below 60 degrees at night, you should not be running the unit overnight as this will cause freezing to occur. If this is not the case, then you should change out the air filter because a dirty air filter also contributes to freezing.
