Furnace tune-up and safety inspection. Cleaned and serviced all 3 furnaces. Tested all mechanical components. Cleaned all sensors. Changed all filters and changed all humidifier pad filters. Found all 3 ignitors needed to be replaced due to heavy corrosion. Replaced parts. The customer requested new thermostats in the upstairs hallway and the downstairs dining room. Replaced thermostats. On the basement/main furnace, found water underneath the inducer motor. Disassembled the inducer motor and tightened all screws along the collector pan, and resealed the gasket going from the collector box to the inducer motor. There is no more water coming from the unit at this time. All systems are clean, heating, and operating properly at this time. First visits on the VIP Service Plan.
