Top 10 Common Causes Of Air Conditioner Compressor Failure

Some air conditioner problems are not going to be that costly, if the reason turns out to be a failure of the AC compressor, for sure it will put a big cost from your pocket or wallet. 

However if you don’t want to face any inconvenience of an HVAC system malfunctioning, learn more about the compressor of the air conditioner. It works like the heart of the air conditioning unit. 

10 common causes of AC compressor failure

1. Electrical failure

Acids develop in your framework because of electrical issues making different pieces of your AC glitch too. Power floods can likewise bring about electrical issues in your forced-air system.

Corrosive and oxidation development is generally a noticeable indication of electrical issues in your HVAC framework. A prepared proficient can recognize corrosive development during a normal investigation, making the fixes before it goes crazy.

2. Blockage of condenser coils

The absence of upkeep assumes a major part in hindering your condenser loops. On the off chance that you keep on running your framework in this condition, your blower can overheat and quit working totally.

3. Overheating of compressor

Moreover, overheating is a typical reason for blower disappointment, and there are many elements at play. Assuming direct daylight falls on your outside unit and there is lacking ventilation around it, it makes your unit’s blower overheated. High voltages can likewise harm the engine making the blower overheat.

Also, filthy loops, low refrigerant levels, and absence of protection; all can add to blower overheating, at last bringing about blower disappointment.

4. Evaporator motor displacement

Assuming that your AC’s evaporator engine is uprooted, it can constrain the refrigerant to get back to the blower. This pushes the blower oil out of its place, and your framework can confront grease issues. It makes the blower lose its productivity over the long run, and at last, it will stop working.

5. Low refrigerant levels

However you won’t cool your home without a sufficient measure of refrigerant in your climate control system. It is a not unexpected misinterpretation that refrigerant levels decline with time. Your forced-air system doesn’t go through the refrigerant. Assuming the levels are low, there is possible a spillage that should be arranged directly.

Low refrigerant levels decline the strain, which makes the blower work more diligently to push the refrigerant in the framework. Ultimately, the whole blower will implode.

The absence of support can build erosion and cause breaks in the AC curls. Hence standard support is the best way to stay away from this issue later on.

6. An excessive amount of refrigerant in your unit

Thinking about how the overabundance measure of refrigerant got in your unit? Have you at any point had an issue of low refrigerant level and called a specialist to fix it?

A less qualified individual may not know how to top it off appropriately and wind up filling it more than whatever is required. The refrigerant levels should coordinate precisely with the amount indicated by the producer. Significant degrees of refrigerant can prompt expanded strain in the framework causing untimely AC blower disappointment.

7. Absence of lubrication

Your HVAC needs the right measure of grease to work ideally. Without sufficient grease, the mileage will expand, making your blower work more enthusiastically. At the point when there are low degrees of oil your blower parts rub against one another. This makes little parts fall to pieces and are let free in the framework.

Loss of oil is for the most part because of spillage from the evaporator condenser pipe associations or the blower shaft seal. An overemphasized blower is probably going to separate sooner than its normal life expectancy.

The specialists will check the oil levels, make any fundamental changes and check whether the oil siphon turns out great.

8. Stopped up or damaged suction lines

Over the long run, the pull lines of your cooler can foster breaks and openings, impeding the refrigerant stream in the framework. This puts weight on your blower as now it needs to utilize additional ability to siphon sufficient refrigerant through the unit bringing about a breakdown. One of the apparent signs is a lessening in the cooling limit.

Assuming that you notice your unit isn’t cooling like it should, call an HVAC master to view the attractions lines.

9. Soil and debris stuck in the outdoor unit

Open-air contaminants, dust, trash, residue, and dampness can enter your open-air unit and cause issues for your blower.

This can build the temperature inside the blower and can cause oil carbonization on the release valve. Oil carbonization brings about buildup development and makes the valves spill. Spilling valves further increment the temperature making more harm to the blower.

You can keep away from this issue by booking yearly Ac checkups.

10. Inaccurate sizing of suction lines

Assuming your pull line is excessively long or excessively short, it can cause AC blower disappointment. Wrong estimating can construct pressure and overheat the blower.

However this issue for the most part emerges when an undeveloped or beginner expert endeavors to fix the line and introduces some unacceptable size. It is best 100% of the time to call an expert for any AC fixes. They realize what sort of attraction line is most reasonable and they will introduce the right length of the pull line.


Once you identified any issues with the compressor you have got a few options. Whether you can go to repair it replace the compressor or also the entire condenser unit. It suggested hiring professional help for thorough repairs and inspection to get the system of HVAC in working condition again.

 If in your AC some small problem is caused like low Ac pressure repair, so it may not charge anything big in the repair process like the compressor problem.
