Tech arrived at a tune-up/ IAQ estimate. Upon inspection, the capacitor was out of tolerance. The condenser coils were hosed off to assist with air flow across the coils. The refrigerant was within range. The filter was dirty. The blower area was dirty and there was growth present in the system. There was ductwork that was not sealed properly in the attic. Tape was applied to these areas. The Delta was within range. The customer was informed of recommendations today. He is interested in the IAQ 1000 Filter, 200 UVC System / Air Cleaner and Level 2 Duct Cleaning. He will speak with his wife and will call us back. He would like a follow up next week if we haven't heard from him by then. The system was functioning upon departure.
