1. Dirty coils.
When dust, grime and mineral scales build up on the condenser coil, the air conditioner can’t expel enough heat from the system and it’s forced to run constantly trying to cool your space. The increased pressure and temperature can cause the compressor to overheat and fail.
2. Blocked suction lines.
When your air conditioner’s refrigerant lines become blocked or damaged, the first thing you’ll notice is that the unit is not cooling as effectively. If the problem is not fixed, once again the increased pressure and temperature cause overheating and AC compressor failure.
3. Low refrigerant charge.
If your system’s refrigerant lines develop holes or cracks, the air conditioner leaks refrigerant. After a while, the level becomes so low that the compressor has to work harder to pump enough refrigerant through the system to cool your space. The strain can eventually cause the compressor to break down.
4. Incorrect suction line size.
If your refrigerant line develops leaks and needs to be replaced, make sure you get an experienced AC technician to do the job. A line that’s too large or too small for your system can cause premature AC compressor failure.
5. Too much refrigerant.
If a less-than-qualified person works on your air conditioner and inadvertently adds too much refrigerant, or even the wrong type of refrigerant, it can be a deadly mistake for the compressor.
6. Electrical problems.
An electrical failure can result in a buildup of acids that cause a great deal of damage to other parts in addition to the compressor. If you have a failed compressor, make sure the technician tests for the presence of these acids. If he finds them, an electrical burnout has caused damage throughout the system that is probably not worth fixing.
But electrical problems are often easily preventable when an experienced tech inspects your system: he can spot and repair damaged wiring, fuses and contractors before they take down your system and cause AC compressor failure.

7. Contaminants in the system.
The high heat and pressure in an air conditioning system, not to mention the locations where they are typically housed in New York City (outdoors, on rooftops, in crawl spaces) can introduce any number of contaminants that can cause damage. These include air, moisture, dirt, debris, leaves, soot, acids, and even bird and pest droppings.

8. Inadequate oil lubricant.
To take the heart comparison a step further, think of your air conditioner’s oil lubricant like the blood in your body. If there’s not enough, the system can’t work properly and all kinds of problems can result, including AC compressor failure. When your system is regularly maintained by a trained AC professional, he will check the lubricant levels and the condition of the oil pump to prevent this problem.
