Customer called about 1 unit being completely down and another had leaked bad. The upstairs system has an electrical issue. I have 120 at 1 leg but 6 on the other. I advised the customer to contact an electrician to resolve the issue. The system that had leaked, had the coil frozen due to dirty filter. We changed the filter. That system was running and cooling properly when I arrived. 1 system down due to electrical issue.
