For the super tune-up I inspected the furnace and condenser. I'll equipment was measuring with in manufacture specs and running well. Customer stated they had poor airflow in the living room and upon inspecting the return plenum I noticed there was a significant amount of water pulling under there. I checked the drain line and condensate pump and the condensate pump was not working, I checked in the Attic and noticed the copper line was connected to another copper line via flexible tubing with hose clamps and was not secure. I resecured the line and turned power off to the condensate pump turn it back on and got it working again. Due to the amount of water damage to the unit I do recommend them replacing the condensate pump to ensure it stays working throughout the summer with a large amount of water that will be being produced. Additionally I recommend a compressor saver, and a redesign of their duct system in the attic as it is old and there is air gaps in the connections.
