Came out to look over furnace and put new gas valve in. After looking over the system, the heat exchangers have a lot of dark spotting but all the rings are Intact and no cracks or holes. Blower cabinet is pretty dirty. Blower motor is leaking a little bit of oil and has a lot of dirt build up on it. Blower capacitor is reading 10.49uf and the recommended is 10. Evap coil is clean. Burner cabinet is really dirty. Gas valve was leaking. Talked with you about the price and the MSC. You decided not to do the gas valve today due to price. I left estimate with invoice on the gas valve. System is not up and running when i left.
