I performed a single cooling maintenance on a 2017 gas system. I checked amps, capacitors, filter, electrical, drains, and cleanliness. During my thorough evaluation, I noticed a couple areas of concerns. I discovered that the blower capacitor is failing 18.5/20. According to manufacture spec, it needs to stay above 19. The outdoor unit has a reasonable amount of build up present. I would advise a chemical bath to assist in the removal of the debris.
