Common Overcharged Car AC Compressor Symptoms

Hello there! Ready to enrich your knowledge with another fun blog? You are in the right place then. Today’s blog is about overcharged car AC compressor symptoms, risks and possibilities. And since we care for you a lot, a bonus point for you. We also have a column about the appropriate amount of refrigerant for the proper functioning of the car and long life! So let us begin with our first question:

Can You Put Too Much Refrigerant In-Car AC?

The first question that arises in everyone’s mind is that is it safe to keep coolant jar full to the neck? How much refrigerant is excess? The fluid should not overflow when the car is accelerating or takes sharp turns. If you are not a professional, chances are you will mess up and overfill refrigerant.

So basically the answer to the above question is NO. Doing this can promote unwanted problems such as slugs. Moreover, since the coolant is liquid, it is highly contagious and will take no time to spread the calamity to other parts too.

Can Overcharge AC Damage Compressor?

As we know, anything in excess does more evil than good. Same goes with overcharging. It not only heats up the compressor more than safety level but also puts extra unwanted load over the compressor. As a result, the performance is reduced exponentially and the battery life diminishes significantly. In such a situation, the initial symptom is under-cooling. It will stop working and functioning properly. Overcharge develops a condition know as slugging. It means due to extra refrigerant overflowing, the compressor, as well as other internals, undergo damage vigorously.

Common Symptoms Of Over Charged AC?

How to figure out that something is wrong with the AC or more accurately, with the AC compressor which is just an outcome of overcharged AC. Here are a few most common and noticeable symptoms which may alarm you:

Slugging, loss of ability too cool effectively in a short time, inappropriate pressure points, excessive heating in evaporator coil or compressor, unwanted noises like rattling and hissing, poor performance, high pressure, malfunctioning system, fissiparous circuit, condenser overflowing with fluid, etc.

How Much Refrigerant Does My Car AC Needs?

After knowing the cons and overcharged car AC compressor symptoms, it is now time to meditate upon preventing from letting it happen. It can be done easily by maintaining a healthy refrigerator mark. According to experts, just keep the fluid level almost an inch below the rim of the jar. Anything above that is considered to be in surplus.
