hvac not comming on when turned on by control panel

February 20, 2011


I noticed the ac wires were chewed through and bare wires touching each other. the control panels both work but when commanded on to blow air out, i get no heat and of course no Ac. is there a breaker? maybe a circuit board. the central ac unit is in the attic, and the home was built in 06

The bare wires are most likely the root cause of your problem. There is a circuit board on the air handler that is part of the furnace. Chances are the shorted wires have either blown a fuse, blown a transformer or shorted out the circuit board.

Contact a local Air-conditioning contractor to have a qualified HVAC technician diagnose the problem. There are no consumer serviceable components in the furnace or condensing unit.
