Tech arrived at a 2 system warranty tune-up. It was raining. Upon inspection, the upstairs capacitor was out of tolerance and replaced. The wrong filters were installed allowing unfiltered air to enter the system. The blower area and ductwork was dirty. There was biological growth present. The Deltas were within range. The drains were clear and the sump pump was functioning. The customer was informed of recommendations today. The customer decided to move forward with adding a compressor saver to the upstairs system compressor. He will speak to his other ac company about the cleaning and UVC system and would like a follow up at the end of April. The systems were functioning upon departure.
