Arrived at clients for two systems cooling maintenance. Did thorough evaluation of both systems. Set both thermostats to cooling. Flushed both condensate drain lines with water. Mini capacitors for both indoor systems were weak. Client did not approve replacement. There was no water safety’s for attic unit. Recommend ez trap water safety as well as wet switch flood protection. Outdoor capacitor for downstairs unit was weak as well. We found a leak in the downstairs evaporator coil. Client wanted to seal the leak and top off the unit. We were not able to go with that option. Client would like comfort specialist to come out tomorrow 5/1/2020 at 10am to go over possible replacement of both systems. Both systems are operational.
