The reversing valve directs refrigerant flow to change between heating and cooling modes. When it fails or gets stuck, your system may blow cool air in winter or warm air in summer. Our licensed technicians are experienced in diagnosing and repairing or replacing these valves to restore your heat pump's proper function efficiently.
