Diagnosis and repair of insulated walk-in cold rooms — panels, doors, evaporators, condensers and control systems — restoring holding temperature fast to protect perishable stock.
A walk-in cold room that drifts above temperature is almost always losing its hold through the gas circuit, an iced-up evaporator coil or a breached door seal. We restore the panel, seal and refrigerant charge, then verify the room holds temperature under a full load before we sign it off. Site C's commercial strips and taxi routes bring constant foot traffic, which keeps its independent grocers, food traders and takeaways running long hours with refrigeration to match.
