How to Know if an Air Conditioner Compressor is Broken?

time2022/06/22

The air conditioner compressor is an important part of the air conditioner as it is responsible for the heat transfer function of delivering the conditioned air to the different rooms. If it's broken, your air conditioning unit won't be able to produce cold air.

Air conditioning is one of those items that many of us are grateful for because it saves us during the hot months, but many don't give much thought to the whole operation. While it's easy to just go to your unit and enter the temperature you want, you have to be aware of these signs if your air conditioner compressor is broken.


The air conditioner compressor is an important part of the air conditioner as it is responsible for the heat transfer function of delivering the conditioned air to the different rooms. A compressor runs refrigerant through your equipment so it can produce cool air. If your A/C compressor fails, your A/C unit will not be able to produce cold air.

Changes in temperature and flow

While there are many signs that an air conditioner compressor is bad, the main sign is your electricity bill. If you find that your electricity bill is climbing for no apparent reason, your air conditioner compressor may be worn out. When the air conditioner compressor wears out, it can't compress enough gas. This means your compressor will run longer than it needs to cool your room, which is why your bills go up.

Also, take care to reduce the amount of cold or warm air coming out of the vents. When the compressor fails, the air temperature may be higher than normal. If you notice an increase in temperature in your home, it means your compressor is no longer maintaining proper refrigerant pressure or flow, which is why warm air is coming out instead of cold air.

Noise from equipment

If you turn on the air conditioner and notice louder than normal noise, your compressor may be starting to go bad. Your compressor can be noisy for a number of different reasons, including loose bearings or leaking bearings. A loose bearing will usually make a grinding sound, while a leaking bearing will make a screeching sound.

As soon as you notice any unusual noises, you should call a service technician to check your equipment. While it's easy to think the noise will go away, just by letting it run, you could further damage your device.

Puddles or leaks

Puddles and leaks are also a huge indicator that something is wrong. While dirty and clogged coils can cause water leaks, bad compressors can also leak refrigerants. If you notice any leaks, stay away and call a service technician right away, even though your first instinct might be to clean up the leak or puddle. A service technician will be able to diagnose the problem while keeping you safe.

Daily maintenance of compressor

There are three important things you can do to keep your compressor running longer. First, maintain routine maintenance. The second thing you should do is be careful when landscaping around the exterior unit. Vents can be damaged, even if they look like they can take anything. Finally, keep plants, leaves, or other debris 2 to 3 feet away from your equipment so they don't restrict airflow.
