ac over fill and now rough idle and wanting to stall Sign In

Hi, I recently had my ac serviced and it was done improperly, I was told the high side was too full. They I guess evened out the levels and It was working, I didn't drive my car very much but with in a short time my ac was acting weird it started to sort of cut off and fluctuate in cooling and my car started to idle rough and try to stall out when I ran the ac?
What happened to my car when the high side was too full and why is my car acting like this?
what should I do? Help!
Thank you in advance!

It is completely obvious that these people have no clue what they are doing. Refrigerant charge is done by weight. There is a specific weight charge for every vehicle. If they charge the correct amount and the pressures are too high, then there is something else wrong with the system.

It is very dangerous to run an AC system with the pressure too high. Not only will it not cool properly but it will destroy the compressor.

You need to get this to a COMPETENT shop that is highly experienced is AC diagnosis.

Suggestion: Get this overcharge which is both high and low fixed ASAP to exact amount system requires or depending in what this is you could be walking over this. It's choking on overfill. The risk of things busting, even a belt required to use at all could be there never mind other damage.
Hurry and hot as it is in many places don't use A/C, defog, defrost get this put right now up https://youtu.be/1-dQLmc7lOY to tow it if choking like that.
Long weekend, one of a few techs that would know probably are not working get going and find a real place that just maybe might take this on today,

Someone had zero clue about this to allow it to hap
