Tech arrived for a 2016 2 system Armstrong Air system tune-ups. Upon inspection 3 of the 4 capacitors were out of tolerance. The contactors were in working condition. The condenser coils were dirty and were hosed off to assist with air flow across the coils. There was no observed surge protection. The filters were relatively clean. The drain systems were clear and bleach was poured. There were no drain safeties on the systems. The Deltas were within range. The customer was informed of recommendations today. The customer will budget for repairs in the future and will consider becoming a member at that time. The systems were functioning upon departure.
