Responded to a call in Philadelphia, PA 19118, where the homeowner reported a gas smell coming from the furnace early this morning. The system, originally installed in 2018, hadn’t been serviced in several years. During inspection, our technician found a small gas leak at the union to the heater and also noticed rust buildup on the igniter spark rods. We recommended replacing the gas union, spark rods, and air filter to ensure safe and efficient operation before the heating season ramps up. The customer was relieved that we located the source of the odor quickly and scheduled a follow-up repair appointment.
