Many commercial catering businesses will invest in a cold room, but these vital pieces of cold kit need to be managed efficiently to keep overall operating costs down. Here are some of our favourite tips to enjoy all of the benefits without the huge energy bills.

Regularly Maintain and Service

A cold room will rely on a regular maintenance schedule in order to perform at its best. Take your manufacturer’s advice and always invest in a professional service to ensure that every component part is operating as it should. This will help it to run efficiently and also nip any smaller problems in the bud as they arise, preventing expensive repair jobs.

Make Sure the Coolant Level Is Topped Up

Refrigerant coolant is a vital gas that provides heat transfer in the energy cooling system. If it drops too low, cooling reduces and inefficiency increases. Keep checking the levels in your system and top up as necessary.

Wash the Evaporator Coil

If your evaporator coil gets dirty, it simply won’t work as effectively and will prevent the system from circulating airflow. Clean it at least every quarter so that the efficiency of the cooling mechanism is retained. You’ll need to speak to your supplier to get an accurate frequency estimation based on the cold room location, its age and so forth.

Replace Old Compressors

Similarly, if your compressor starts to show signs of ageing – perhaps by overheating or failing to cool quite as well – then it’s time to replace it with a new one.

Get a Great Service Team

A good HVAC service team will make a real difference when it comes to providing operational resilience for your business. Invest in a servicing contract with a KPI for rapid callouts for your walk in cold rooms from This will prevent excess spoilage in your cold room if anything goes wrong and help to get your business up and running again with the minimum of disruption.

Check Door Seals

All too often, cold room owners are hot on checking the mechanics of their cold room but forget to keep an eye on the door seals. If these start to degrade, then the entire unit will lose efficiency. Regularly check seals and replace then when they show signs of age.
