Yes, that's a classic sign of a failing heat pump reversing valve, a common repair we handle in Walterboro. This valve directs refrigerant flow to change modes. When it gets stuck—often due to wear or debris—your system can't provide the right comfort. Our technicians can diagnose the valve issue quickly and perform the necessary repair to restore your system's proper function, whether it's a repair or a replacement of the component.

Reduced cooling is a frequent symptom of a dirty evaporator coil. Here in Walterboro, pollen, dust, and humidity accelerate this buildup, forcing your system to work harder. Don't ignore it, as this strains the compressor. We recommend calling J & J for a system repair check. Our technicians will clean the coils thoroughly, check refrigerant levels, and ensure all components are working correctly to restore efficiency and prevent further damage.
