Maintenance & Upgrade
Cold room repairs and maintenance for commercial refrigeration systems. We repair cold rooms, walk-in fridges, walk-in freezers, compressors and door seals.
Glotech Group provides cold room repairs and maintenance for businesses that rely on commercial refrigeration every day. We repair and service cold rooms, walk-in refrigerators, walk-in coolers, freezer rooms and commercial refrigeration systems used in restaurants, butcheries, bakeries, food production facilities, supermarkets, hotels, catering kitchens, warehouses and industrial sites in Cape Town & across Western Cape.
When a cold room is not cooling correctly, running continuously, leaking water, building up ice or causing stock temperature problems, fast diagnosis is important. A refrigeration fault can affect stock safety, production, service and business continuity.
Our technicians inspect the full system, identify the cause of the fault and advise on the correct repair. We assist with compressor faults, gas leaks, evaporator problems, condenser issues, electrical faults, door seal problems, thermostat faults, drainage issues and planned maintenance.
Call Glotech Group on 067 153 8332 for cold room repairs and commercial refrigeration maintenance.
A cold room fault is not always caused by one obvious component. Poor cooling can be linked to a gas leak, blocked condenser, faulty compressor, iced-up evaporator, damaged door seals, incorrect controller settings, failed fans, poor airflow or a defrost problem.
Glotech Group checks the full refrigeration system before recommending a repair. This helps prevent repeated call-outs and ensures the real cause of the problem is addressed.

Glotech Group can assist when your cold room, walk-in fridge or freezer room has problems such as:
Cold room not cooling
Cold room temperature too high
Cold room running continuously
Compressor not starting
Compressor overheating
Evaporator iced up
Condenser blocked or dirty

Gas leak or low refrigerant
Water leaking from the cold room
Drainage problems
Door not sealing properly
Damaged door seals
Thermostat or controller faults
Electrical faults
Freezer room ice build-up
Walk-in cooler not holding temperature
Walk-in freezer not freezing properly
Unusual noise from the refrigeration unit

Repeated breakdowns
A commercial refrigeration system works harder when coils are dirty, fans are weak, drains are blocked, door seals are damaged or refrigerant levels are incorrect. Regular maintenance helps keep the system clean, efficient and reliable.
Our cold room maintenance service can include:
Condenser coil cleaning
Evaporator coil inspection
Fan motor checks
Drain line checks
Refrigerant pressure checks
Leak detection checks
Compressor inspection
Electrical control checks

General refrigeration system report
Maintenance is especially important for businesses that cannot afford stock loss or downtime, such as restaurants, butcheries, food producers, supermarkets, hotels and distribution facilities.
Where an ageing room has widespread insulation, door and refrigeration problems, a new commercial cold room installation may be more economical than repeated repairs.
A fast, structured repair process designed to minimise downtime, restore system performance, and ensure reliable commercial refrigeration operations for your business.
We inspect the cold room, walk-in fridge, cooler or freezer room to understand the fault. This includes checking temperature performance, equipment operation, airflow, controls, door sealing and visible system condition.
We identify the likely cause of the problem and explain the repair required. Where possible, we advise whether the fault can be repaired, whether a part must be replaced or whether the system needs further testing.
We carry out the approved repair, which may include compressor replacement, fan replacement, leak repair, controller replacement, door seal replacement, electrical repairs, drain clearing or refrigeration system work.
After the repair, we test the system and check cooling performance. We also advise on maintenance steps that may help prevent the same issue from returning.
Reliable cold room, freezer room, and commercial fridge solutions designed to maximise performance, reduce downtime, and support business operations.
We repair cold rooms that are not holding temperature, not cooling properly, running too long, tripping power, leaking water or causing stock temperature concerns.
Our technicians inspect the refrigeration system, controls, fans, coils, pipework, electrical components, doors and general room condition to identify the cause of the fault.
Walk-in refrigerators are used for chilled storage in restaurants, hotels, food suppliers, butcheries, bakeries and commercial kitchens. When a walk-in refrigerator fails, it can put fresh stock and daily operations at risk.
We repair walk-in refrigerator faults such as poor cooling, compressor failure, fan motor issues, thermostat problems, electrical faults, drainage issues and door seal damage.
We repair walk-in freezers and freezer rooms used for frozen food, meat, seafood, ice cream, bakery products and bulk frozen storage.
Common freezer room problems include ice build-up, slow temperature pull-down, door sealing issues, defrost faults, compressor problems, fan failures, drain freezing and low-temperature control faults.
If the insulated structure and refrigeration equipment have reached the end of their useful life, Glotech Group can also quote on a complete walk-in freezer installation.
A faulty compressor can prevent the cold room from cooling and may cause the system to trip, run loudly, overheat or fail completely. Our technicians assess the compressor, pressures, electrical supply, controls and system condition before recommending replacement.
Where compressor replacement is required, we install a suitable replacement compressor and complete the necessary refrigeration work, including system checks, vacuuming, charging and testing.
Damaged cold room door seals allow warm air to enter the room, causing temperature loss, condensation, ice build-up and unnecessary load on the refrigeration system.
We replace cold room door seals and freezer room door seals where suitable. Correct sealing helps the room maintain temperature more effectively and reduces strain on the compressor.
Where the problem extends beyond the seal to a damaged door frame, panel joint or room structure, professional insulated panel and cold room door repairs may also be required.
Regular maintenance helps prevent breakdowns, temperature issues and expensive emergency repairs. We provide maintenance for cold rooms, freezer rooms, walk-in fridges, walk-in coolers and commercial refrigeration systems.
Maintenance can include coil cleaning, pressure checks, leak checks, fan inspection, drain checks, controller checks, door seal inspection, defrost checks and general system performance testing.

Yes. We assess the compressor and refrigeration system before recommending replacement. If replacement is required, we install a suitable compressor and test the system after the repair.
Yes. We can replace cold room and freezer room door seals where suitable. Damaged seals can cause warm air entry, condensation, ice build-up and temperature loss.
Common causes include low refrigerant, gas leaks, compressor faults, dirty condenser coils, failed fans, iced-up evaporators, faulty controllers, poor door sealing or electrical faults. A technician needs to inspect the system to confirm the cause.
Ice build-up can be caused by warm air entering the room, damaged door seals, poor door closing, defrost faults, blocked drains, evaporator problems or incorrect controls.
Commercial cold rooms should be serviced regularly, especially in food, hospitality and production environments. The ideal maintenance frequency depends on usage, operating hours, stock value and site conditions.
