We performed a heating tune up on 4 gas systems. Two systems are from 2023, one is from 2017, and one is from 2014. We checked amps, filters, electrical, cleanliness, air quality, and safeties. The systems are performing well. Customer spoke about an issue with the system that services the dining room area. We could not replicate the issue. The master bedroom unit has an emergency pan that is rusting through. The main living room unit’s blower motor has bearings that are becoming worn. The 2023 unit has a contactor that is heavily pitted and burnt. Customer recently had a power surge and one of the thermostats had been reset. We spoke about adding surge protection to the equipment. Customer declined options at the time of service for blower motor, emergency pan, contactor, and surge protection.
