Today I completed your anuall cooling maintenance. I tested all 3 of your systems in the cooling mode. I replaced all air filters, tested refrigerant and all electrical operations and cleaned systems. Bottom level system we’re both testing as they should at this time. I found that the capacitor on the top level system was testing under factory specifications and the system is low on r22 refrigerant which is no longer made. I recommended having system replaced. Thanks for having me out today, Eli
