Blew My A/C? Blew Pressure

My wife was complaining about the A/C in my 01 X5 not being cold enough. I topped off the freon in the system last year and I thought it worked fine, but to please my wife I got some more freon and charged my system. Unfortunately I wasn't paying attention and probably blew the system. As I was charging I heard a loud woosh and cloud of what appears to have been freon exiting the system somehwhere down near the compressor. Someone please tell me there is an overpressure release valve or something similar that is easy to reset/replace.

Failing this - please tell me the real answer if you know it. I will be taking it to an A/C specialist tomorrow but am afraid of hearing I have damaged the system.

Any suggestions/help is appreciated.

I dont do cars but i do hvac. Overcharging a system can slug out the compressor. Overcharging can make it blow warm too.

Having an overpressure release valve would make good sense. I hope you haven't done too much damage. I assume your compressor is working fine then?

Re: Blew My A/C? Blew Pressure

Some compressors have a pressure relief valve, so you may be okay. If you are going to do the DIY thing at least use something like this


Using a low side guage should keep you from over charging the system.
