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. Graceland mixes formal housing with small business premises, and its local butchers, caterers and food shops rarely have the luxury of closing for a failed cold room.
