There are a few reasons why your car air conditioning might be making a hissing sound. In this article, we’ll go over a few ways to troubleshoot and fix the issue.

If your car’s AC is making a hissing noise, the first thing you should do is check the compressor. The compressor is the component in your AC system that pressurizes and circulates the refrigerant. If the compressor is malfunctioning, it can cause a hissing noise.

If the compressor is functioning properly, the next thing you should check is the refrigerant lines. If the lines are loose or damaged, it can cause a hissing noise.
