I performed a heating maintenance on a 2013 York gas system. I checked amps, filter, electrical, cleanliness, and safeties. I noticed that the units did not have surge protection and that the inducer motor is pulling 1.0amps out of 1.06amps. I brought the inducer motor to the customer attention and they would like to wait before addressing it. I installed 2 surge protectors at the time of service and collected for the work.
