Cold Room Not Cooling
A cold room that isn't cooling is the most urgent fault we handle. The cause can be a failed compressor, a refrigerant leak, a faulty controller, a blocked condenser or an electrical issue. Our technicians run a full diagnostic to find the exact cause and repair it — not guess at symptoms.
