Performed QA on Mitsubishi Single Ductless unit. Homeowner said system is working very well and she is very happy with it. Ran system in cooling and tested amp draw and voltage. Poured water into the drain to make sure it was draining. Adjusted the drain tubing in the garage so it was pitched better. It had one or two spots where it was bellied. Completed checklist form in system. No follow is needed.
