Is it normal for my truck's air conditioning compressor...?
to make a leaking noise for a minute after I have used it? I know it is my air conditioning because I tried listening for the noise without running the a/c and I heard nothing after I turned off my truck. My air conditioning stills works and the noise does go away after a few minutes after my truck has been off; im assuming from the compresed air being released. So is this normal or should I have it looked at? Thanks for the help.

Your air conditioning system has a high pressure side and a low pressure side. The hissing noise you hear are the two pressures equalizing after the system was running then shut off. This is normal. All a/c systems do it.

The compressor obviously compresses and there is still pressure when you cut the engine. It is normal for the aircon gas to flow back to equalise the pressure.

if you ever have to add gas then you have a leak. Until then do not be concerned about it.
