Arrived to find t stat set at 74 and satisfied at 74 Client had stated system would not cool this past Saturday and temp went up to 81. Removed entire charge and weighed in factory charge. Fan speed is set accordingly and adjusted mechanical txv per specs to now gather pressures and temps of 124/346 sh9 sc12 VSAT43 LSAT 106. Temp split is right at 20 degrees I have 80 degree air entering air handler and 61 degree air exiting. Home will take some time to cool down today as I have been turning system off frequently to continuously adjust txv. If problem still occurs made client aware we will return to fully insulate attic.
