Tech arrived at a warranty tuneup. Upon inspection, the capacitor was within specs. The contactor was in working condition. The Delta was within range. The filter was dirty and allowed unfiltered air to enter the system. The blower area and ductwork was dirty. The drain was clear and bleach was poured. The customer was informed of recommendations today. She decided to move forward with adding an UVC System and Air Cleaner and an AprilAire filter upgrade kit to the system. The customer would like for this to be performed next week, any day except for Wednesday. The system was functioning upon departure.
