Arrived onsite for no heat service call. Performed diagnostic and found 2 faults. Fault in the combustion pressure sensor system and a fault in the fuel delivery system. Provided homeowners with options for repair or replacement the furnace. As the furnace is 18 years old and has other parts that are systematic. Homeowner elected for Bandaid Repair. I was able to secure the parts and install them. Confirmed operation of the heating system.
