4 Reasons to Repair Your Commercial Chiller Instead of Replacing the Entire System

Posted on: 17 March 2017

If your commercial chiller starts to show signs of wear, you'll be forced to either replace or repair it. While there are benefits to replacing the entire system, it's usually more beneficial to simply call in a professional chiller repair company like Maximus Chillers.

Here are just four reasons why.

1. Installing a New Chiller Can Be Disruptive

People often underestimate just how much work goes into replacing a chiller system, particularly if they were not part of the business in question when the chiller was installed. This isn't just a single system that can be removed with ease. The piping will run through walls and ceilings, and the chiller might be large enough to necessitate the moving of other larger pieces of machinery. When the new chiller is installed, a new piping system will need to be fitted; this can sometimes follow the layout of the old system, but this might not be the case.

Repairing parts of a chiller can also be disruptive, particularly if you need to get at some of that piping, but it's hard to imagine a scenario in which it could be more disruptive than a complete replacement.

2. Efficiency Depends Mainly on Replaceable or Cleanable Parts

People will often argue that it's better to replace a chiller because the newest models are a lot more efficient. In one way, they are exactly right: Newer chillers will almost always be more efficient. However, the parts of a chiller system that most strongly influence efficiency include the compressors, pumps and motors. By replacing these items instead of the entire system, you'll benefit from a boost to efficiency without having to put up with the inconvenience and expensive of a complete replacement.

You might also find that efficiency is suffering because of a part that can be easily cleaned. For example, many chillers begin to consume more power when their pipes become fouled. In such cases, a complete replacement is unnecessary; all you need to do is have the pipes cleaned.

3. It Takes a Long Time for Chillers to Be Replaced

It's not like you can walk down to your local supermarket and pick up a new commercial chiller. In fact, the length of time between ordering the chiller and having it up and running can be considerable. The new chiller will have to be shipped, the old chiller will have to removed, and then the new chiller will need to be installed and inspected. That all takes time, which can make replacing a chiller on the fly more than a little bit inconvenient.

Most commercial chillers need to run constantly, so it's best to replace your system when the current one is still working instead of when it has broken down. This will reduce the amount of downtime you experience without a properly operating chiller. If you really have your heart set on a replacement, consider repairing the system now and then replacing it a year or so down the line.

4. Worn Out Chillers Could Hide an Underlying Problem

Finally, keep in mind that chillers are generally supposed to have very long service lives. Experts suggest that most screw chillers will last for 15-20 years and most centrifugal chillers will last more than 25. If you do find yourself having to consider replacing the system long before it should have begun to suffer from extended use, it could be that you haven't been properly maintaining it; alternatively, you might have been using the system incorrectly.

If you choose to just straight up replace the system, you run the risk of treating the new chiller in the same manner. In contrast, having the system repaired will mean benefiting from the knowledge and experience of a professional; they will be able to look through your daily logs and inspect your system to check whether the damage was caused by any mistakes on the part of you or your staff.
