Many people rely on their home's central air conditioning to keep their home cool during the hot summer months. Like any appliance, an air conditioner can develop problems. Luckily, in many cases, A/C issues can be diagnosed and repaired by an HVAC technician. However, when the air conditioning system's compressor fails, it can be extremely costly to repair and you will most likely be told that your better option is to purchase a new air conditioning unit. Continue reading to learn more about common reasons compressors fail and how you can help prevent problems with your A/C compressor:
Coils are Dirty
An air conditioning unit has condenser coils inside and if they are not cleaned regularly, dirt, debris, grime, and mineral scales can begin to build up. When this happens, the air conditioner is unable to dispel heat efficiently, which causes the unit to run constantly in order to cool down your home. This leads to an increase in pressure and temperature inside the A/C unit which can cause the compressor to overheat and fail completely. This easiest way to prevent this is by having your air conditioner tuned up annually, preferably in the spring.
Refrigerant Charge is Too Low
Refrigerant lines inside an air conditioning unit can crack or develop holes, which causes the refrigerant to begin to leak out. When there is a refrigerant line leak, the refrigerant charge becomes too low and the compressor has to work much harder to pump the refrigerant through the system. If this problem is not solved promptly by having the leak repaired and refilling the refrigerant, the compressor will eventually break down.
Not Enough Oil Lubricant
The components inside an air conditioning unit need proper lubrication in order to run smoothly and efficiently. When there is a lack of oil lubricant, the parts can't function properly, which puts a strain on the entire system, including the compressor. This strain can cause parts to stop working entirely, leaving the compressor to pick up the load, and the extra wear and tear on the compressor can lead to failure. Lubricating the components of an air conditioning system are one of the things that are done during a regular air conditioning unit tune-up.
Suction Lines Blocked
A refrigerant leak is not the only thing to worry about with an air conditioner. The suction lines that transport the refrigerant through the system can also become blocked or clogged, preventing the refrigerant from flowing properly. This type of issue can also cause temperature and pressure to build up, causing the compressor to overheat and fail.

Hello, my name is Cece. Welcome to my site about HVAC repair and equipment replacement. The heating and air conditioning systems at my place of business were always failing at the most inopportune times. After bringing in a professional to take a look at the problem, we learned that the components were exhibiting signs of extreme wear. We decided to perform an equipment upgrade to restore the functionality of our HVAC system. The HVAC repairs fully solved the problem in very little time. I will use this site to talk about similar repairs you might need to complete on your own HVAC systems. Thanks for coming by.
