Signs your furnace needs a look
It won't turn on: often a thermostat, a tripped breaker or an ignition failure
It blows cold air: a dirty filter, pilot or ignitor trouble, or a failing gas valve
Banging, squealing or rattling: usually a worn blower motor or loose parts
It turns on and off over and over: an airflow restriction or a thermostat problem
