Furnace maintenance Furnace is very loud on start up. Venter motor internal bearings are seizing up. Blower motor is drawing high amperage, more than the rating plate specifications. Inspected heat exchanger with inspection camera and noticed it is very corroded internally. Took clear pictures and showed customer the internal conditions. Provided information what needs to be done to keep furnace running. Customer would like repair quotes vs replacement unit quotes. Did notice water heater water inlet is very corroded and leaking water. Recommend replacing unit before it leaks more. Did make customer aware that the chimney does not have a chimney liner, and would require upgrading the water heater to the power vented Style.
