Performed the diagnostic and found that the condensation drain line was clogged. Options for repair were presented to the homeowner, and Karla chose to have the drain line cleared. I cleared the drain line and washed the air filters. I rinsed off the evaporator coil with cleaning solution and tested the system. The system is now operational, and I could see the cleaner draining out of the drain line while the system was running. I allowed the system to run until clear water was flowing tough the drain line.
