Commercial Refrigeration Maintenance

Refrigerant vented in the atmosphere is severely damaging to the environment



Maintenance or PPM(Planned Preventative Maintenance) as pros call it, is a must-have for any refrigeration and air conditioning appliance. The truth is that PPM is designed to extend the lifespan of your equipment. It may seem that having maintenance done once or twice a year is a waste of money but its quite opposite to that.

We offer a light commercial equipment maintenance service for as low as 40 GBP per unit all over the London and home counties.

Maintenance is a proactive, preventative work that reduces the risk of the major breakdowns and therefore reduces overall running costs. On-site, it’s checking, cleaning, taking notes of any current problems or possible problems in foreseeable future. The Maintenance Report will be also drawn up on site. After you sign the report, it will be sent back to our office and a quote will be provided for you to rectify any remaining issues with your equipment. Some services we quote will be pick-and-choose and others will be in your own interest. If You agree with the quote we have provided all the remaining parts will be ordered and fitted for you in a few days or as soon as the parts are available. VAT invoice will be provided.

The purpose of maintenance is to keep any refrigeration and air conditioning equipment in good working order, prevent major breakdowns, avoid costly repairs and inconvenient downtime that also costs money as a loss of sales and customers.

In the medical industry, you may need to provide a certificate to your insurance company proving that equipment you use to store perishable medicines is in good working order.

Sometimes insurance companies require a certificate of the maintenance for reasons unknown to us. 

The best way to think about it is that fridge is a heat exchange device. Any device that is meant to absorb and reject heat must have a heat exchange devices. Those devices are in need of regular maintenance as per specifications of the manufacturer in order to function properly. If you don’t get the maintenance done in accordance with the manufacturer recommendations, the manufacturer warranty, parts warranty and labour warranty become invalid. Some manufacturers insist on the condenser cleaning as often as every two months.

If we talking about fridge maintenance, then we mostly mean condenser cleaning. Every now and then (1-2-3 times per year, depending on your site conditions and peculiarities) its a good idea to clean the condenser off the dust, hairs,  grease, till receipts, plastic bags and even dead mice. 

What if you don’t do the maintenance

In short term, it may cause all sorts of anomalies that you cannot even notice. At first: power consumption goes up(think about how much it will go up if you have 20 commercial fridges in your restaurant or shop), compressor runs all the time, fans also, temperature in the fridge is stable but it never reaches the set-point, evaporator is icing up, fan starts to catch the ice(making noise) until it will get fully iced up and most likely cease, refrigerant does not evaporate in the evaporator and floods the compressor washing the oil off the crank and piston. Later on, the lubrication ceases and shortly the compressor also ceases. Compressor still runs but it’s under enormous pressure and it is red-hot, something on the compressor must give in sooner or later and depend on the type of equipment and site specifics may add up in cost if service is delayed. You can call the Fridge Service Company on 02030703858 rather sooner than later. 

Maintenance DIY

If you DIY, then you probably will brush it off or hoover it and you will get off with this in short-term as you only cleaning the surface. DIY is ok as long as you don’t apply any force what so ever to the condenser fins as they are very soft and in no circumstances should be bent. For this reason, it’s best to use a soft brush and “non-contact” hoovering method. In long term, the condenser will get clogged up inside and the hoovering won’t help anymore. Then you need to call the pros to blow out the condenser or clean it with chemicals depending on circumstances. As mentioned above the lack of maintenance can lead to serious compressor damage that will cost a significant amount of money to rectify.
