Tech arrived at a tune-up. Upon inspection, the capacitor was within specs. The contactor wire was burnt and replaced. The condenser coils were hosed off to assist with air flow across the coils. The filter was dirty and replaced. The blower area and ductwork was dirty. The drain line was draining slowly. The customer was informed of recommendations today. He will try and clean the drain himself and will call us if he needs anything. The system was functioning upon departure.
