No heat. Found inducer motor seized up. Replaced inducer motor (refer to photo) and cycled the furnace on to verify operation. Upon arrival I noticed all CO detectors going off Jason said they started going off last night and they had to evacuated the home. I performed a combustion test verifying that the home was free of carbon monoxide. Please keep in mind if CO detectors do not reset after being outside they may need to be replaced. Due to the age and condition of the sytem I highly recommend having a cleaning done so we can get a better idea of the current condition of the system. Job complete
