Our average individual experience is greater than 15 years. We understand your business, and your equipment. Commercial refrigeration maintenance can extend equipment life by years & save big on electrical consumption.
Commercial Refrigeration Maintenance is critical, especially when it comes to Walk-In Coolers, Freezers & Ice Machines. This is especially true when it comes to line coolers. All refrigeration needs to expel heat. The majority of units do this through an air-cooled condenser coil. This is done by drawing air through the coil. This causes dust & debris to form fairly quickly on the condenser coil. Failure to clean condenser coils on a regular basis will increase electrical consumption & lead to major system component failure such as burnt wiring, a failed condenser fan motor, a restricted metering device or a failed compressor. These are some, but not all of the possible consequences of lack of maintenance. Without a doubt poor maintenance will decrease the lifespan of equipment & increase electrical consumption.
There are things to be done between contractor clean & checks that can really help. The following is a checklist of tasks you can perform to help extend the life of your commercial refrigeration equipment.
1.Visually inspect the condenser coil on self-contained refrigeration. Often the condenser coil is behind a cover at the top or bottom of commercial coolers & freezers. Condenser coils can also be located at front right or left on a unit & also at the back of a unit. The condenser cover can usually be removed with a Philips screwdriver. Occasionally a ¼” or 5/16” nut driver is needed to remove cover.
2. Check door seals (gaskets). Your refrigeration unit has worked hard enough cooling the conditioned space. Don’t let warm kitchen air seep in through torn or split gaskets. Slowly inspect all four sides of door gaskets for rips or tears. Make sure the gasket actually seals well on all four sides. Gently clean gaskets with a mild soapy water to remove food debris.
3.Check any drain line outlet visible. Usually condensate drains are located at the base of coolers in the back on refrigeration units that have the compressor on the bottom. On units that have top mounted compressors the drain may also be located at the top of unit. Clear end of drain. The following is a tip on how to keep cooler & freezer drain lines clear. You may insert a straw into drain outlet. Wrap a damp cloth around where straw goes into drain. Blow air into straw & up into drain while firmly holding straw in drain with damp cloth. This will help clear restrictions. The drain should also be blown out by a contractor a few times a year.
It is recommend checking these three things around once a month at minimum. It is also a good idea to have a professional maintenance of equipment a minimum of twice a year is the best way to increase equipment reliability, longevity & efficiency.
A contractor can quote a maintenance plan by doing an equipment count. Professionals will clean the coils & drains far better than an end user can. This is important for proper operation of equipment.
The following is a comprehensive list of the types of things that should be checked & serviced during a contractor preventative maintenance visit.
Pressure cleaning of all air-cooled condenser coils
Pressure cleaning of all drains
Refrigerant level check
Inspection of door gaskets / seals
Inspection of hinges & or automatic door closers
Oil motors or bearings when oil ports exist
Check unit thermometer for accuracy
Check unit insulation
Inspect unit wiring
Inspect unit compressor
A detailed report on each unit along with make, model, serial number & temperature
A detailed list of repairs found to be needed
