Came on 11/13/25 for a no heat on main floor system. After diagnostic found that the pilot light was off, there was no 24v coming to the little control board, extremely dirty blower wheels, bad blower’s capacitor, bad blower motor, furnace is rusty and in bad shape, no secondary drain pan. Homeowner installed a wet safety switch on their own. Homeowner came down to check my work and I told him I was going to get my scope to check their heat exchanger since furnace is over 10 years old. And they refused. They said they know their system is old and they do not want me check their heat exchanger. I could not thoroughly diagnose the system. System needs to be replaced immediately. If they call us, tell them they need to upgrade their furnace. Furnace is 38 years old. The only band aid option is to upgrade their furnace.
