Client had an issue with drain line backing up. Did a complete evaluation of all AC system, found a lot of sediment and slime in drain line, outdoor capacitor was very weak, and compressor had high startup amps. Gave client solutions for issues with system, however, system is 11 years old and recommended replacing due to age and cost of repairs. Client needs to discuss replacement with spouse and just wanted to do minimal repairs for now. Got approval from client to install an in-line drain guard cleaner, cleared and flushed out drain line, and replaced dual run capacitor. Cycled and tested drain in AC system, all operations OK at this time.
