Came out today to diagnose a ac system that is leaking. Upon arrival the customer showed me where the system was leaking from. I powered down the Rheem system. Model #Rihanna-21j2suaa, serial #T m4495 5980. I removed the access panel and found the drain line was clogged in between the air handler and condensate pump. I connected my stinger vac the the pvc drain line at the condensate pump and turned it on. Almost immediately I could feel the clog get sucked up. I placed the drain line back in the condensate pump and tested the system by pouring multiple bottles of water into the air handler and observing the condensate pump it out. I ran the condensate pump 4 separate times. I also noticed that the air flow was poor. I removed the air filters and the air flow improved. I replaced 2- 20x20x1 air filters. These return ducts are located in a room where dogs get washed and blow dried. This causes the filters to clog more frequently. Recommend checking the air filters weekly. Bill out per o
