So my car sat for 5 years while I was working on rebuilding the motor. I got the motor back in and I’m having issues with my A/C.

The A/C system was left in the car intact. I did not undo any lines or open the system. When I turned it on the compressor didn’t engage. I got some refrigerant and it wasn’t registering so I added some and the clutch on the compressor engaged. It was a little low so I added some refrigerant. Still hot aur was coming out when the system was set to cool.

Then I noticed this odd hissing sound inside the car when the compressor was running. Any ideas what it could be? I’ve never messed with A/C.

Here is the link to my video of the noise it’s making.
