Customer complaint: customer has to turn thermostat up during the day to keep home from getting too cold. I found Hot air from attic is leaking into Home and down the wall that thermostat mounts to. This is causing the thermostat to register much higher than room temperature during the day. Customer complaint: system stopped blowing cold air. I found supply flex duct in crawl space disconnected! I reattached with three screws for temporary attachment. Customer plans to have work done next month, requiring removal of flex duct. Checked cooling performance. Set blower speed to match condensing unit/coil combination. Sub cooling was zero. I topped off Freon (0.5#, 410A). Suction: 141 (49) suction line: 57 to 60. Head pressure: 351 (107). Liquid line: 99.
