Why is my indoor fan running all the time?


You may have the thermostat set in the “on” instead of “auto” position.  When set to “on” the indoor fan will continue to run even when the system is not calling for heating or cooling.  This will constantly filter the air in your home, not just when the system is heating or cooling.  If you have the thermostat set to the “auto” position, the indoor fan will only come on when the system is calling for heating or cooling.
