Visited a new homeowner in Philadelphia, PA 19132, who received one of our mailer coupons and scheduled a routine maintenance service for her gas furnace located in the basement. The system was last serviced in 2021, so our technician performed a comprehensive furnace tune-up to ensure all components were in proper working order. We inspected and cleaned the burners, blower assembly, and heat exchanger, checked the safety controls and gas pressure, and verified overall system efficiency. Everything tested within safe operating range, and the system is now running smoothly and ready for the colder months ahead.
