Tech arrived at a 2 system tuneup. Upon inspection, the main system duel run capacitor was out of tolerance. The condenser coils were hosed off to assist with air flow across the coils. The filters were not sized correctly and were allowing for unfiltered air to enter the system. The blower area and ductwork was dirty. The drains were clear and bleach was poured. The system reached complete ignition. The flame sensors were scorched. The customer was informed of recommendations today. He will contact home warranty for repairs and will think about upgrading his filters.
