WHAT IS INCLUDED IN COMMERCIAL REFRIGERATION SERVICE?

Door Gaskets – Cleaning door gaskets is simple and requires only a damp cloth, soap, and water. To avoid any harm to the compressor, make sure to fix any tears as quickly as you can. To avoid harm to the door or stress on the condenser, the gaskets must be changed right away if it is broken.

Cleaning Coils – Allowing a significant build-up of dust or debris can make a unit less efficient, which means it uses more energy, costs more to operate, and has a shorter lifespan. This may potentially result in a compressor failure, which might cost a lot to fix if not discovered right away.

One of the simplest refrigerator maintenance tasks is routinely cleaning the condenser coils. Make sure to clean your appliance at least once every three months to maintain it operating effectively and at its best.

Cleaning of Drains – It might take a long time to clean your drain lines. It’s advisable to hire a skilled expert to clear your drain pipes once a year to make sure they are not blocked with dirt or mould. The service technician will typically disinfect the interior of your unit while cleaning it.

Routine Maintenance – Routine servicing for commercial refrigeration systems entails more than just periodically inspecting various parts. These systems must be regularly inspected, evaluated, cleaned, adjusted, and replaced with new parts since they must operate continually to maintain the proper temperatures.

Checking Refrigerant Level – Our staff also examines the refrigerator’s refrigerant level when maintaining your business refrigeration equipment. If the refrigerant level is low, you will be aware of it before it affects cooling or causes a problem for your business.

Other Issues Check-up – Serious problems like overheating and dirt accumulation can be quite expensive to address. However, by performing routine maintenance on your refrigeration systems, major issues may be identified before they become impossible to resolve. Additionally, this may eliminate the need for pricey replacements. If you work in the hospitality sector, it’s crucial to remove dirt build up and make repairs so that clients aren’t at danger of contracting foodborne diseases. While it’s true that everything eventually needs to be replaced, industrial refrigeration systems can benefit greatly from servicing. The downtime required for system maintenance is often frustrating. However, it’s undoubtedly the most preferable option when weighed against the downtime of a significant emergency repair.

CONCLUSION

All restaurants, nightclubs, bars, and foodservice establishments require refrigeration. It’s essential to keep your refrigerators functional and capable of sustaining precise temperatures.

Inefficient energy use and mechanical stress caused by dirty refrigerators, coolers, or freezers may result in the appliance breaking down during the worst possible moment and costing extra money.

Common Indicators that your fridge or freezer needs maintenance, repair or service

When your refrigerator or freezer is malfunctioning, several signals or indicators might identify the issues with your appliance. A few of the several signs that show that your commercial fridge/freezer repair in London is required are discussed below

  1. The fridge/freezer not working properly – The obvious indications that a refrigerator is broken are warm food or a defrosting freezer. If the refrigerator has an ice or water dispenser, look for power lights on those devices. Open the doors and look inside for lights. Keep an ear out for the fan’s running noises. If there is electricity but the refrigerator does not seem cold enough, adjust the thermostat inside; otherwise, refrigerator repair services are required.
  2. There is a buildup of frost and the freezer is excessively chilly – Temperature swings within the refrigerator can be brought on by frost accumulation on the evaporator coils. Self-defrosting technology is used by frost-free refrigerators, and it runs around four times each day. A refrigerator that has damaged coils. If the frost is removed, the freezer returns to normal; however, if it builds up once again, it is necessary to contact for freezer repair.
  3. Condenser issues – A series of cooling coils are located beneath the refrigerator, and when they are unclean, they affect how the refrigerator functions. A cooling fan is also included with these coils and must be cleaned regularly. If cleaning the refrigerator does not work, it can be broken and need repair or service to be kept in working order. Then you need refrigerator repair services.
  4. Compressor issues – Several things might be damaged if the motor is working yet the temperature inside the refrigerator is higher than usual and setting the thermostat does not solve the issue. The thermostat, relay, or defrost timer could need to be replaced or repaired, or the compressor itself might be broken.
  5. Water on the floor from the refrigerator – Water damage can result from both ice on your surfaces and liquid on your flooring, so you should have this issue treated soon away. Many leaks are not severe enough to spill water into the floor in front of your refrigerator, which makes them go undiscovered.
