Freezer Repair

Commercial freezer repair in London requires same-day response and engineers who carry the right parts to complete the repair on the first visit. A failed commercial freezer puts thousands of pounds of frozen stock at risk within hours. Our F-Gas certified engineers provide 24/7 emergency response across all 32 London boroughs.

Frozen food begins to degrade above -15°C and is typically considered unsafe for resale once it has risen above -9°C for any period. The window for safe recovery is short. Calling us as soon as a freezer fault is noticed gives the best chance of saving your stock and minimising losses.

Commercial Freezer Faults We Repair

We repair all types of commercial freezer faults across all equipment categories.

Upright Commercial Freezers

Upright commercial freezers are common in restaurant preparation areas and food retail. Typical faults include compressor failure, refrigerant loss, evaporator fan failure, defrost system faults, and door seal deterioration. We carry spare components for all major upright freezer brands including Foster, Williams, True, and Gram.

Chest Freezers

Chest freezers used in catering and food retail can suffer compressor failure, thermostat faults, refrigerant leaks, and lid seal problems. We carry replacement compressors and thermostats for all common chest freezer models and can complete most repairs in a single visit.

Blast Freezers and Blast Chillers

Blast freezers operate at very low temperatures (-35°C or below) and use high-capacity refrigeration plant. Faults in blast freezers can include compressor failure, refrigerant system issues, defrost controller problems, and air blast fan failures. We have experience with all major blast freezer brands including Irinox, Williams, and Foster.

Remote Condensing Unit Systems

Many commercial freezer cabinets use a remote condensing unit located in a plantroom or on the roof. Faults in remote systems can be harder to diagnose, as the fault may be in the cabinet, in the remote plant, or in the pipework connecting them. Our engineers are experienced in diagnosing and repairing remote condensing unit systems of all capacities.

Walk-In Freeze Rooms

Walk-in freeze rooms combine the panel structure of a cold room with a high-capacity low-temperature refrigeration plant. Faults include condensing unit failure, evaporator coil ice-over, defrost system failure, and door seal degradation. We carry out both emergency repairs and planned maintenance on walk-in freeze rooms across London.

What Happens to Frozen Stock During a Breakdown

The rate at which frozen food warms up depends on the thermal mass of the cabinet, ambient temperature, and how full the cabinet is. A well-insulated, fully loaded upright freezer will typically maintain temperatures below -10°C for 4 to 6 hours after failure. Chest freezers and walk-in freeze rooms hold temperature for longer.

Actions that help protect your stock during a breakdown include keeping the freezer door closed as much as possible, moving the most temperature-sensitive items to an alternative freezer if available, and documenting the temperatures at regular intervals. This documentation supports any insurance claim for stock loss.

My commercial freezer is not reaching temperature but is still running. What could cause this?

The most common causes are refrigerant loss, a blocked or dirty condenser, a defrost system fault causing ice build-up on the evaporator, or a failing compressor. We diagnose the specific fault on attendance using temperature measurement, refrigerant pressure gauges, and electrical testing.
