I came back out for a not cooling well. They said the ac would run sometimes and sometimes not. I checked the system over and found that the dual capacitor was extremely low. That the reason why it wouldn’t run every time. The system is still under its parts warranty, so with approval, I installed a new dual capacitor. I cycled the ac and checked all operations. I also double checked the drain line. All working properly. I did recommend a hard start kit, to ease the strain on the compressor and dual capacitor. They didn’t want to install it at this time.
