The furnace is blowing cold and won't shut off

Furnace repair in Mcdonough

Your furnace blower is running. The thermostat is on heat. You don't have any heat. You might have a bad limit. Turn off the power and leave it off until the serviceman arrives. A dirty filter can cause this. An old limit can too.
