A compressor is considered the heart of an automobile’s air conditioning system, and a bad car A/C compressor can quickly make it unusable. Recognizing the early symptoms of a bad car A/C compressor can help prevent more expensive repairs and complete system failure. Below are some symptoms of a faulty compressor that drivers should always be on the lookout for, as delaying repairs can lead to further damage to your vehicle’s A/C system.
Hot Air Coming from Vents
This is often one of the first things that drivers will notice. The whole purpose of air conditioning is to produce cold air that will cool down the vehicle, so if the air coming out of the vents is hot, it defeats the purpose of having A/C. While warm or hot airflow might mean that your refrigerant levels have become depleted, it can also mean that you have a compressor that is near the end of its service life. In many cases, a failing compressor is unable to properly circulate refrigerant, resulting in weak or warm airflow.
Unusual Noises When A/C Is On
When operating your vehicle’s A/C, you shouldn’t hear anything out of the ordinary. Those who are hearing strange sounds whenever their air conditioning is activated almost certainly have a compressor issue. This is because once this component goes bad, it may begin to produce grinding, squealing, or rattling noises when the system is running. These sounds often result from worn internal parts like bearings or loose components inside the compressor.
Compressor Clutch Not Engaging or Stuck
As with a manual transmission, most A/C compressors come with a clutch. The clutch will connect to the automobile’s engine for the purpose of extracting power. However, compressors will use this power only when necessary, engaging and disengaging as needed. If the car A/C compressor clutch becomes stuck, seized, or fails to engage, the compressor cannot work since it won’t receive adequate power. In some cases, clutch failure may be repaired separately, but often it indicates internal compressor damage, requiring full compressor replacement.
Refrigerant or Fluid Leaks
A/C compressors are manufactured with internal bearings which are responsible for preventing refrigerant leakage. One of the jobs of a compressor is pressurizing refrigerant so it can cool. The trouble is that over time, this tends to wear down the bearings due to the constantly pressurized environment, which will then cause the bearings to leak out the refrigerant. You may notice visible fluid around the compressor or reduced cooling performance due to low refrigerant levels. Leaks are a common sign of compressor wear and should be addressed promptly to avoid further system damage.
What Happens If You Ignore a Faulty Compressor?
Some people are strapped for cash and do not want to spend it getting their compressor replaced, but the consequences for not doing so can be severe. Like most mechanical issues, a failing A/C compressor will continue to worsen over time.
For instance, if the bearings inside the pulley are bad, it might cause a lockup which could stop your engine from working while you’re driving the vehicle! In severe cases, a seized compressor can place additional strain on the engine belt system, potentially causing belt failure or engine stalling. Obviously, if you’re driving on a freeway or high traffic area, this can be dangerous and increase the risk of an accident.
