What Happens When Ac Compressor Fails?

The compressor in your air conditioner is frequently called the system’s brain. Your air conditioner cannot operate without the compressor, so the Ac compressor fan fails is a major problem. Less air will emerge from the vents when your Ac compressor fan fails, and that air may be heated. The system may also operate continuously without cooling your home. This can lead to a higher electricity cost because refrigerant isn’t pumped through the system.

To stop such a failure, you must comprehend what occurs when your Ac compressor fan fails.

What Is Failure Of The Air Conditioning Compressor?

The refrigerant must be compressed for the AC compressor to push it through the cooling system and remove heat and humidity from the air. The compressor is frequently referred to as the heart because it pumps refrigerant, which is comparable to how your heart pumps blood. Unsurprisingly, the compressor is one of the most dependable parts of the complete AC system. It doesn’t require much maintenance and AC Repairing Dubai to function optimally for the duration of the AC unit’s lifespan. However, if it happens, your entire AC unit will also malfunction.

If your Ac compressor fan fails before it should (normally 10 to 20 years), it’s probably because of another problem with the AC system. The most frequent cause of AC compressor failure is an underlying problem straining the system until the failure. Understanding this is crucial since it implies that AC compressor failure is avoidable!

You can avoid failure by identifying and resolving the problem producing stress. Additionally, the new compressor will probably malfunction if you replace the compressor but fail to address the root problem. Scheduling routine AC Repair Springs for your unit will help you avoid an AC compressor failure because many of the problems that lead to one are avoidable.

The top signs of an AC compressor failure include:

Limited Airflow

One of the initial signs that an Ac compressor fan fails is decreased airflow. If you believe your home is not chilly enough, you may continue to lower the temperature over the first few days, making it difficult to notice the change. Placing your hands under the vents is the best way to determine whether the airflow is weak. If you experience little to no airflow or warm air when it should be cool, your air conditioner’s compressor may malfunction. It would be best if you addressed it immediately by contacting an AC Repair near me.

Noisy Banging Sounds

You should be informed immediately if your HVAC system begins to make loud banging or growling noises and you observe associated tremors. Failure of the AC compressor is one of the issues it could indicate. The compressor is having problems starting and is most likely to fail in the future based on these AC noises. The compressor’s electrical parts failing is also indicated by the hammering noise. As soon as possible, turn off your appliance and contact AC Repair Dubai to have your system thoroughly inspected.

Inability to switch on the compressor

Here’s how it begins: You realize that your apartment is too hot and the AC isn’t keeping it at the desired temperature. The fan appears to be operating OK when you inspect your indoor unit. But after that, you examine the condensing unit. Although the compressor is not operating, you can hear the fan running, and the device has power.

The thermostat should be lowered as a first step to try to activate the compressor. If it doesn’t, one or more underlying issues may have already caused it to fail. You shouldn’t mess with it now; hire AC maintenance Springs in Dubai to figure out what went wrong.

You might have to choose between making repairs or replacing the item. Repairing a broken compressor can be very expensive. It might not be worthwhile to spend the money on the repair if your system is old.

The System Emits Warm Air

Warm air escaping from the system even while the condenser appears to be working is another sign that the AC compressor will fail. A malfunctioning compressor makes it impossible for refrigerant to be pumped through the system, which reduces cooling capacity.

It’s crucial to remember that a refrigerant leak might also be the source of this symptom. This may be why the system has been gradually decreasing its cooling capacity. Refrigerant leaks can lead to compressor failure because as the system loses refrigerant charge, it stresses the compressor.

Why Do AC Compressors Malfunction?   

Electrical Error

Electrical failures can be caused by faulty wires, fuses, and contractors. Acids accumulate in your system due to electrical issues, which causes other AC components to break down as well. Your air conditioner may experience electrical problems as a result of power surges.

Typically, the accumulation of acid and oxidation is a blatant sign that your HVAC system has electrical problems. During a routine examination, the AC Repair spring can find acid accumulation and fix it before it gets out of control.

Condenser Coil Obstruction

Your condenser coils might become blocked largely due to neglect. They cannot discharge heat when they are clogged with dirt and dust, which strains the compressor. Your compressor may overheat and quit working entirely if you keep running your system in this manner.

The Compressor Is Too Hot

Compressor failure is frequently brought on by overheating, and there are numerous contributing causes. Your outdoor unit’s compressor can overheat if there isn’t enough airflow around it and it receives direct sunshine. High voltages may harm the motor, leading to an overheated compressor. Furthermore, filthy coils, low refrigerant levels, and a lack of insulation can all cause the compressor to overheat and eventually fail.

Motor Displacement of an Evaporator

The refrigerant may be forced to return to the compressor if the evaporator motor in your air conditioner is dislodged. This forces the compressor oil out of its position, which may cause lubrication problems for your system. Over time, it causes the compressor to become less effective until it eventually stops working.

 Low Levels of Refrigerant

You cannot cool your house without enough refrigerant in your air conditioner. Contrary to popular belief, refrigerant levels do not decline with time. The refrigerant in your air conditioner doesn’t run out. If the levels are low, there probably is a leak requiring immediate attention from AC installation Dubai experts.


The lesson is never to overlook any warning indications now that you are aware of why AC compressor failure occurs. The delay will worsen the situation rather than solve it. You might choose an AC maintenance Springs contract for AC installation in Dubai if you cannot maintain your system on your own. By doing this, the underlying problems can be resolved before they can harm the compressor.
