Performed diagnostic on system. Unit is not cooling. Found compressor was not turning on. Found Unit completely flat on r-22 refrigerant. Went over recharge price for refrigerant. Charla decided that itâ€™s not worth fixing and they will be replacing the unit. They purchase their systems through Ferguson and have fire and ice replace it. Helped put a portable AC unit in that they had on site. System is not operational upon departure, left power to unit off.
