Furnace tune-up and safety inspection. Tested all mechanical components. Cleaned all sensors. The system is operating adequately at this time. The customer has a lot of water damage due to the collector box gasket failing. The system is 9years old; however, the warranty may not be valid due to the builder's ownership, not the homeowner's. Multiple pictures are on file to represent damage. Providing customer estimates for replacements/repairs. The humidifier has stopped working, and the inducer motor is weakening, causing flame rollout on startup.
