16 year old Trane Gas furnace and AC. System not heating, high limit tripped and blower motor has failed. Inspected blower wheel, inducer motor, and heat exchanger. The Neat exchanger is cracked in multiple places on the 2 left cells. I can only access these cells but is most likely they are in the same condition. The blower wheel is impacted with debris and seized. The inducer motor bearings are worn and inducer is over amping. Due to the age, condition, and repair cost exceeding replacement, I recommended updating this equipment. The home requested we send out an install supervisor, I scheduled this for today asap, only system for the home. Thank you for choosing T.E. Certified, have a great weekend!
