Refrigerant lines are often ran on the exterior of the home during system replacement or when replacing leaking lines. Sometimes they are left without being properly anchored and can be very unattractive. A Line Set Cover can conceal and protect the lines and eliminate the possibility of pests entering the home through the penetrations. Rain Guards are also important for diverting rain water from the roof away from the outdoor unit. Excessive water can cause component failures and interrupt normal system operation.
