Aftermarket vs. OEM Parts

There are literally hundreds of aftermarket suppliers out there. The question is “what is the difference in quality as opposed to price?” In some cases, it may seem like the same part you would get from the manufacturer. The difference is that when you use an aftermarket part, you have the potential to unintentionally void the warranty you may have had on your equipment.

The manufacturer provides parts specifically engineered to make your unit perform as it should. You may save a few dollars purchasing aftermarket parts, but what happens when something does not work properly, and you have no recourse through the manufacturer? Keep in mind that just because it fits, does not mean the product is working as the manufacturer designed. Take a look at drift eliminators, for example. Different eliminators cause different casing pressures in the condenser, which leads to decreased efficiencies. Another opportunity is air filters. Many offer filtering characteristics, but not at the level of filtering as originally designed.

There may be good reasons to go the economical route, but do not make that decision lightly. Here are five reasons why you may want to stick with the original manufacturer’s parts, at least in certain situations:

1. Quality. We are referring to fit and function here. Have you ever gone to install a new replacement part and the holes didn’t match up? This is much less likely to happen with OEM parts designed by the manufacturer.

2. Warranty & Support. Occasionally, the installation of a non-OEM part poses a threat to warranty coverage on a particular piece of equipment. OEM parts themselves may also have a better guarantee than those from 3rd-party suppliers.

3. System Compatibility. With the increasing use of connected sensors and integrated data collection to monitor and record operating conditions, making sure related components are compatible is a primary concern. Manufacturers commonly use proprietary software, and other aftermarket suppliers may not have access to the code that ensures proper operation.

4. Reliable Distribution. Large manufacturing companies have been around for years, meaning they have had a long time to refine their supply chains and distribution networks. While you may believe you are saving a few hundred dollars by buying that expensive part from an aftermarket vendor, you may be actually costing your self-time and money when production is held up because the part does not work or is delayed.

5. Durability. A part is a part, right? Except you have no idea what is in the alloy or plastic that is used to manufacture the part. OEM manufacturers have spent over 100 years formulating recipes for metal and coatings that resist corrosion and contribute to increased safety standards. Is your aftermarket part made of the same materials? In some cases, you won’t know the answers to this question, and this could be dangerous when it comes to your Ammonia Refrigeration System.

While aftermarket parts are often more cost efficient, and are sometimes just as reliable as an OEM, take care in your selection and use of aftermarket parts. Of course manufacturers are going to tell you to use their parts, but only you can decide how the pros and cons stack up for your system.
