Service diagnostic found that the drain line was clogged before getting to the condensate pump. The primary pan would then overflow and leak water into the closet. I also found the blower wheel is dirty. I spoke with the homeowner and he chose to have the drain line serviced at this time. I cleared, vacuumed and then tested the drain line and condensate pump. Verified the system is draining outside. The system is working at completion of service.
