Customer said furnace was not working. Found the main control board was bad. And also the inducer motor is bad. Due to age Parts were hard to find, but found them at Sid Harvey. Left a quote for repair. Customer is also going to get a quote for a new furnace. Cannot guarantee functionality of other furnace parts until main control board is replaced, which could potentially increase cost of repair. Recommend replacement due to age of furnace and uncertainty of operation. Furnace is from 2007.
