13AUG2023 Jason Brown Arrived for new customer no cool. Spoke with Brian about the systems performance. It’s been cutting out and finally stopped it was squealing recently and struggling all summer. Inspected AC and coil. Found dual run cap out. Replaced capacitor with individual caps. Cycled equipment checked amps and charge. Inspected coil found coil to be clean and insulation levels adequate. I did however find the system running on 2 14” returns. A 4 ton system is designed to move 1600 CFM of air. Right now we’re around 900-1000 CFM recommend adding an additional 16” return to correct return air.
