Dispelling the Myth of New Semi-Hermetic Compressors

Those in the market for a new semi-hermetic compressor have options, but they may be less abundant than consumers tend to realize. Compressor remanufacturing has become big business and is also the norm. That has led to the term OEM (Original Equipment Manufacturer) taking on new meaning.
When it comes to compressors, OEMs remanufacture their semi-hermetic compressors. It is the same process used here at City Compressors. The lone exception is Carrier/Carlyle, which do feature brand new semi-hermetic compressors that are included on new package units. However, there are ample reasons as to why remanufacturing has become the norm for semi-hermetic compressors.
There are many common issues with semi-hermetic compressors as they are prone to oil leakage, inadequate levels of coolant, overheating, contaminants, and improper setting of valves. It is difficult to avoid some of these issues, especially ones where outside contaminants infiltrate the system and flood the compressor. While not all these problems cause an immediate shutdown, they can take a toll over periods of and reduce performance.
To the untrained eye, it remains difficult to detect subtle problems with a semi-hermetic compressor. As these systems have grown, all the components have become more complex, making it more difficult to identify smaller issues. But not all those issues are going to cause the compressors to cease. Some minor issues may simply bring about the need for troubleshooting. This is where the remanufacturing process becomes more financially viable.
The benefits of remanufacturing also generate much less downtime. A full replacement would mean more time lost. Companies, such as City Compressor, have all the necessary parts to provide a customized rebuild. Furthermore, the process is able to remain the same as semi-hermetic compressors are not undergoing wholesale changes. That is also a financially reassuring notion for business owners.
It is never out with the old and in with the new when it comes to semi-hermetic compressors. New is a relative term in this industry, one that has led to common misconceptions. Semi-hermetic compressors can continually be serviced, making them a very unique item. It is a rarity in the modern age that such a powerful and widely-used contraption can be upgraded, fixed, and adjusted over long stretches of time.
This gives credence to the marvels of the remanufacturing process and has made the term OEM a bit obsolete when shopping for semi-hermetic compressors. City Compressors can provide a remanufactured semi-hermetic compressor that will work as good as any you will find on the market.
Common Compressor Issues and How to Fix Them

Upkeep
Because of the economy, not every budget has enough room for preventative maintenance. Therefore, it is understandable as to why some businesses pass on this aspect of service. It is also important to note that evaporators and condensers can accumulate dirt. When either of these parts get too dirty, your system will be unable to charge.Wear and tear
Constant use will cause belts and pulleys to wear out over the course of time. Adjustments will need to be made and this can even be done without the service of a professional. Other components can also fail and that could lead to other problems. For example, failing to change a bad relay will burn out the motor.Keep an eye out
Refrigerant needs to always be charged or else the system could incur icing, which can severely damage a compressor. Meanwhile, a valve that is not properly adjusted will damage the compressor and could cause a liquid floodback. This issue can be alleviated by the quick and easy process of making sure the filter is clean and also doing a check on the super heat.- To make things even easier, here are some simple steps to follow. Compressors are an important component and keeping them functioning properly can be accomplished by adhering to these guidelines:
- Be sure to examine the gauge pressures. These should be operating on a normal level according to the specified box temperature and ambient.
- Run a visual sweep of numerous components, including the oil level and amp draw. As a rule, the compressor should feature 20 degrees.
- Whenever a compressor is replaced, it is a good idea to also replace the driers as well as the contactors A failure to do so could shorten the lifespan of your new compressor.
- Get to know your oil. It is vital to match your refrigerant with the proper oil. There are far more refrigerants to choose from than oils, which are limited to only a few. Mismatching refrigerants and oils could bring about big problems.
