Perform four system home care. Several AC condensers do not have 1 foot clearance between each other. The bedroom and the basement units on each floor and do not have the correct size. Both units are rated at 25 A. Both are currently sitting on 30 amp breakers. Recommended homeowner get wet switched for the upstairs. Homeowner approved installed and tested Wet switch. Couldn’t see drain line for the upstairs unit was a concern so was the leveling condenser pad for the bedroom unit. I replaced all filters today tested all condensate pumps. Homeowner is fully aware of all of my findings, explained all of my findings to him over the phone. I explained to the homeowner since three of the systems are relatively new. He still may be under your labor warranty through the company that installed them. I explained to him if we were to take care of repairs it would be at his cost.
