The refrigeration industry is a massive one, with many different types of businesses using refrigeration equipment. It’s not surprising that there are so many different types of commercial refrigeration failures—and it’s even less surprising that they can be hard to diagnose. Commercial refrigeration equipment is usually more complex than residential units, and the maintenance requirements are often more stringent as well. Fortunately, though, there are several common causes of these problems that you can work on yourself or call in help (24/7) if necessary:

Faulty Installation.

The installation of your commercial refrigeration system is the most important step you can take to ensure that it’s a long-lasting, trouble-free machine. Installation should be done by an experienced technician who knows what he or she is doing and follows strict guidelines from the manufacturer. Your technician should also install new refrigeration equipment according to the manufacturer’s specifications, including:

  • A thorough cleaning and sanitizing of all parts before installation.
  • Proper mounting procedures for each part.

Improper Operation.

Improper operation can be a result of any number of things, including improper maintenance and lack of training. Here are some steps to take when you suspect improper operation:

  • Make sure that your refrigeration equipment is in proper working order by checking the temperature readings and making sure they’re within acceptable limits (see below).
  • Check that all controls are working properly by pressing them and seeing if they respond as expected. If something seems out of place or doesn’t seem right, don’t hesitate to call us at [phone number].

Poor Maintenance.

Maintenance is the most important aspect of keeping your equipment running smoothly. The best way to avoid future problems is by regularly maintaining your equipment and doing preventative maintenance on them as needed.

  • Regularly check all parts of your refrigeration system, including compressors, condensers, evaporators, and fans; condensers can be checked visually or with an electronic tester (which will illuminate a light when they need maintenance).
  • Check that all hoses are free from debris and have no cracks or holes in them at least once every three months; replace any old hoses if necessary but don’t just throw away old ones because they might still work!

Must-Read: Tips to Boost the Efficiency of Commercial Refrigerators.

Inadequate Cleaning and Sanitizing.

  • Cleaning and sanitizing your equipment is an important part of maintaining a safe, clean working environment. It’s also one of the most overlooked aspects of commercial refrigeration repair.
  • The right amount of cleaning and sanitizing will depend on how dirty your air conditioning unit is, how often you use it, and its age. If you have an older model unit that hasn’t been cleaned in a long time or has never been cleaned at all then it may need to be thoroughly cleaned before being used again to ensure proper hygiene standards are maintained throughout its service life cycle.*

Drainage Issues.

Drainage is the process of removing water from the refrigeration system. It’s important to consider how drainage issues can affect your business, especially if you have a large facility or refrigeration system that’s not well-maintained. If you notice any drainage problems, it’s best to take action right away so that they don’t get worse!

  • Make sure all drains are clear and free of debris.
  • Check inside all lines for leaks or other damage (such as rusty fittings). If there are any signs of leakage, contact a professional immediately; otherwise, they may cause serious damage over time due to corrosion.

Condenser Coil Issues.

The condenser coil is a part of your refrigeration system that cools the refrigerant. It’s made of copper or aluminum, and it’s located outside of the building. If you have any problems with your condenser coil, there are three common causes:

  • The metal surrounding it has become corroded due to water damage or poor maintenance practices (such as leaving doors open)
  • Ice build-up has caused it to freeze over time
  • Insulation around this part of your cooling system has failed

Regular maintenance will help Avoid commercial refrigeration failures.

  • How often should you do maintenance?
  • What should you look for when doing maintenance?
  • How to do regular maintenance on your commercial refrigeration system, including what to check and how to fix problems if they arise.*
