Today I came to Monart and Mary Jane’s Edgemont home because the main floor furnace stopped working yesterday. Upon diagnostics of the 20 year old system I found it is extremely poor condition. Both roll out safety switches were tripped. This is usually attributed to a failed heat exchanger. Once I reset the switches I found the system started running but was over heating the combustion chamber. The inducing motor is over amperage indicating impending failure. The condensate pan is leaking acidic condensate into the furnace. The heat exchangers have failed and the system is putting out extreme amount of carbon monoxide. The furnace is unsafe for use until repaired or replaced. I visually inspected the other furnace and found its condensate pan is also leaking and the combustion chamber is very rusted much like the main floor furnace. Furnace install day1 Removed old unit, cut out old venting for both furnaces and ran 2” 636 for both. Placed new unit and made transitions. Hooked up
