The compressor is fairly considered to be the “heart” of an air conditioner. Indeed, any AC compressor failure negatively affects the whole split system, so its condition must be carefully and timely checked.
Before repairing this AC part, technicians make sure to identify the exact reason for the breakdown. But the truth is, the causes leading to a compressor malfunction are very diverse!
Want to reduce the chances of a serious compressor breakdown? We suggest that you get familiarized with a number of causes preceding it, so you can take action in advance and call professional HVAC technicians and save your compressor.
Root causes for AC compressor failure
Dirty AC coils
When dust and dirt build up on the condenser or evaporator coil, the air conditioner cannot cope with hot air removal and must run constantly to cool the room. Increased load can cause the compressor to overheat and, as a result, break down.
When the pipes, which are responsible for the refrigerant supply, get clogged or damaged, the first thing that becomes noticeable is worse performance of the split system. Why? It stops cooling as well as it did before. Not solved in time, this problem will lead to the compressor overheating.
Low refrigerant level
Because of micro cracks on the refrigerant pipes, refrigerant begins to leak. After a while, its level becomes so low that the compressor has to work twice as hard to move enough refrigerant to cool your home. This inevitably leads to AC compressor failure.
Too much refrigerant
The same goes for an excessive amount of refrigerant in the air cooling system. Increased pressure inside hugely complicates the operation of the compressor. Consequently, there’s a high risk of a breakdown and costly repairs.
Electricity problems, damaged wiring and fuses can lead to the formation of acids from the refrigerant and oil, which corrode all parts of the air conditioner. If your compressor is broken, this may be one of the reasons.
Dirt in the system
Outdoor AC units are rarely protected from dust, sand and various debris. They can easily get into this unit of the air conditioning system that is located outside. Such contamination increases the risk of a breakdown.
Poor fan operation
If the fan of the outdoor unit does not work properly, it may cause disturbances in the vital heat exchange process. The consequences include compressor overheating and internal damage.
When your air cooling system fails, the most important thing is to properly reveal the root cause and have it professionally repaired. Fortunately, 80% of AC compressor failures are quite easy to avoid. How? By regular AC maintenance and early identification of the problems mentioned above.
How can I reduce the chances of sudden AC malfunctions?
It’s a well-known fact that compressor repairs typically account for a third part or even half of the price of the air conditioner. So, it is in our best interest to take care of this AC part and prevent possible failures.
As a rule, an urgent replacement or repair of an air conditioning compressor stems from insufficient knowledge as to how to maintain the air cooling system.

- The most important thing to do is regularly clean or replace the filters.
- At least once a year, the AC evaporator and condenser coils should be carefully cleaned.
- Don’t forget about regular refrigerant control. Low amount of it can lead to compressor overheating and bring the entire AC unit out of order.
- Call a local Las Vegas HVAC contractor for overall inspection and cleaning twice a year.
