Tech arrived at a 2 system tuneup. Upon inspection, the upstairs duel run capacitor was almost out of tolerance. Both systems condenser coils were hosed off to assist with air flow across the coils. The downstairs system filter was dirty and replaced. The drains were clear and vinegar was poured. The Deltas were within range. There was growth present in downstairs system plenum. Both blower areas were dirty. The customer was informed of recommendations today. He decided to add a UVC System and Air Cleaner to the downstairs system, as well as replacing the capacitor and cleaning the downstairs system blower wheel. There items were installed tested and functional. The system were functioning upon departure.
