Similar to what a central processing unit does
for your computer, a compressor is known as the heart of an AC unit. It compresses
the refrigerant and pumps it throughout the system to reduce the heat and
humidity from the air. AC compressors are usually reliable and require little
maintenance. However, if it fails to function properly, it is a sign that some repairs
are required.
Here are six causes of an AC compressor
failure.
1. Insufficient Lubricant
The lubricant used in an AC compressor does
what blood does to your body. The lubricant is what adds to the functionality
of your system and keeps it going. When the lubricant is insufficient, the
system is forced to work harder than necessary. After some time, the compressor
fails altogether.
2. Electrical Issues
The electrical problems start small, and if
left untreated grow bigger. If the electrical damage has worsened, there no
repairs can help you out, and the only option is to replace the compressor.
However, through regular maintenance, an electrician can figure out whether or
not there are any damaged wires, short fuses, or other electrical hazards.
Electrical issues in your AC compressor if detected in the early stages are
easy to deal with. If left to stay, they can make your compressor fail.
3. Dirty Coils
With an extended period of use, dirt and grime
tend to accumulate over your AC compressor. It is build up excessively, it
hinders the expulsion of heat from the system. As a result, the system works
harder than usual to cool your living space. With extra pressure exerted over
it, the compressor heats up and fails.
4. Inadequate Refrigerant
Oftentimes, the refrigerant lines form small
holes and cracks. As a result, the refrigerant starts to leak. Refrigerant
leaks must be dealt with in the early stages. However, if these holes aren’t
fixed in the initial stages, the refrigerant will continue to leak. A time will
come that the refrigerant will run so low, that the system will be forced to
work harder. This unnecessary strain will cause the compressor to fail.
5. Excessive Refrigerant
Similar to insufficient refrigerant, excessive
refrigerant can be just as bad for your system. Oftentimes, people make the
mistake of pouring too much refrigerant into the system. Remember, that too
much refrigerant or the wrong kind of refrigerant affects your system, and a
time comes when the compressor seizes to function.
6. Blocked Refrigerant Lines
As discussed earlier, it is the job of your
compressor to pump the refrigerant throughout the system. In the event the
lines are clogged, the clogging results in pressure buildup. As a result, the
system temperature rises, and it heats up. Being overly heated, the AC
compressor breaks down, thus causing you a lot of financial inconveniences.
