Common Causes Of A Commercial AC Compressor Failure

Posted on: 6 September 2018


When your AC compressor fails, your AC will no longer be able to blow chilled air. Instead, the fans might continue to circulate, but they won't keep your home sufficiently cool. There are several reasons why your AC compressor might fail.

Have the Right Amount of Refrigerant

Refrigerant is a crucial part of your AC. When you have too much or not enough refrigerant, this can lead to too much pressure building up for your AC and this can lead to the compressor failing prematurely. To prevent this from happening, make sure to have commercial air conditioning maintenance services charge your AC. 

Clean the Coils

Your air conditioner relies on coils to ensure that it is able to expel heat. If these coils become dirty, your AC might heat up too much and this can lead to the compressor failing. To prevent this from happening, make sure to have a maintenance crew regularly vacuum and brush the evaporator coils.

When your AC is dirty, another consequence is that the refrigerant lines can become blocked or damaged. When the line is damaged, make sure to not repair it yourself because having a refrigerant line that is not the right size can also cause your compressor to fail as a result of overheating.

Beware of Acids

Some AC units will begin to develop electrical problems, which can lead to the buildup of acids. For this reason, you will want to have the electrical problems solved as soon as possible. When the acids build up, they will cause damage to other components in your AC unit and a repair technician might recommend that you replace your AC.

Use the Recommended Lubricant

Lubricants are an important part of a functioning AC unit. If you do not use the right lubricant, your AC unit will have to work harder to pump the refrigerant through the system.

Eventually Replace Your AC

AC units are not meant to last forever. Eventually, the compressor might wear out and you will then need to have it replaced. When your commercial air conditioner is older than 10 years old, you may want to consider having it replaced so your business does not have to suffer through a period without air conditioning. 

The reason why the AC is often replaced when the air compressor fails is because the compressor is the most expensive component to replace. Even when the compressor doesn't completely fail, if it is not properly maintained, it can become very inefficient and raise your utility bills.
