Question a/c video

So I took a video of my a/c compressor earlier with the a/c on. its blowing warm and I was wondering why the compressor is doing this? Is it the clutch? I don't know too much about a/c work, so i was wondering if anyone knew what to do? Heres the video...

It's probably low on freon. It's cycling on and off because the pressure switch detects the low freon and won't let it run. If that happens, the clutch will burn up.

Well, thats the thing i forgot to mention. I added freon to it about a week ago, a full can of the r124 or whatever its called, and it blew cool (not cold) for a bit and now its warm again.

It sounds like you have a leak somewhere in the system and are losing freon (r134a). Have someone pressure check the system or go buy a set of gauges at the parts store and do it yourself.

How do you test it? Would the stop leak kind of r134a fix it?

well thers a few things that could do it.1 is that the system is actually overcharged but you saying it blew cool and now hot kinda knocks that out. 2 since you used a can and didnt have it actually serviced, you could have a bunch of air in the system. believe me ive seen both of those quite a few times. and 3 just low charge ( leak in the system) . easy way to do this is get pag oil with dye, put some in the system and let it run. get a black lamp and the leak will stick out like a sore thumb if its leaking good. the reason i say find the leak rather then plug it with the r134 stop leak is because that stuff coats the complete system with stop leak, not saying it will hurt it but it always could. just find the leak and fix it the correct way.
