Furnace tune-up and safety inspection. The system is from 2006! Tested all mechanical components. Cleaned all sensors. Found f/s and HSI very corroded. Customer agree to replace both parts. Took a lot of pictures in hopes of helping provide detail to the condition of this system. Found the inducer motor is making a loud noise, and is leaking on the back where it connects to the collector box, causing water damage. Found the humidifier pad filter to be very calcified. This system is also an R22 AC system, which I added refrigerant to in 2023. Gave customer estimates for complete system replacement due to age, out of warranty, and the condition of everything. They are considering and will get back to us. The furnace is heating and operating adequately at this time. The system is at the end of its lifespan. Customer renewed VIP maintenance plan. One visit is being used today, and they will have spring/ac visit of 2026 season prepaid. Performed free inspections.
