A/C over pressured

[AmBo]

Hey guys,

I recall being told that our AC is supposed to be around 40-50psi? They tested it at 90psi.

Yea, I'm a baller. I hate the body shop that fixed my AC after my accident. This will be my 5TH return to them to fix it RIGHT.

Sounds like they can't fix it right if they've tried 5 times already.

Your pressure depends on whether or not it's running. If the AC is running the low side pressure should be around 40, that would be throwing out some cold air. If the AC is not running and you put the guages on it depends on the outside tempurature. On an 80 degree day it would be about 90psi on both high and low sides, but that doesn't matter. I would need to know what both the high and low pressures are while it's running to tell you any more. We're just guessing without more information.

Well it's 5x for all different issues. THis is the newest of them that I've experienced so far. It's one thing after the next.

Two kinds of work I never do myself are exhaust and a/c. Exhaust because it is too hard and exhaust shops do not charge much and get it done the first time. A/C because it is too complex and requires too much specialized knowledge and too many specialized tools.

Make sure that when the A/C is turned on that the fans at the rad are running, if they are not then there is your problem

What are the high and low side readings with the A/C running at max and what temp. outside?

 

[AmBo]

Sadly i don't have the tools to get these readings on the fly. It'd have to go to a shop to get this type of information.

Ah ok, pretty vital readings to have to know which direction to look.
