Came back on 06/09/25: per customer they want to go ahead with the previous band aid option I gave them. Properly cleaned both condenser units, installed 2 wet safety switches, installed an ss1 safety switch on main floor system, replaced both furnace capacitors (10uf), replaced both condenser capacitors (main floor: 35/5uf and upstairs 40/5uf), added 2lbs of refrigerant R-410A in main floor system. Added armoflex on main floor system suction line close to the evaporator coil, cleared both condensate drain lines. Tested systems for normal operation l systems are cooling properly at this time.
