How important is A/C Evacuation?
OK, so my AC leaks, probably from the compressor hose fitting O-rings. So, assuming the system now has zero or very little pressure and I pop those fittings off and put new o-rings on in 10 minutes or less, do I really need to evacuate the system before recharging? I'm sure it's a good idea, but is it really necessary?

the once vacuum is achieved and held you can add r134. what about a/c oil? do you have any leaks showing? might need fresh compressor oil. make sure you use the green orings.

Re: How important is A/C Evacuation?
The whole process would be easier if someone hadn't lifted all my A/C equipment out of my garage. I hope they needed it more than I did.

Re: How important is A/C Evacuation?
Great links.
Anyone know the correct fully charged low side pressure for our system? You can buy cans of "drier" on the market to add along with your refrigerant, but I have no idea if they are a good idea.

Re: How important is A/C Evacuation?
Please allow me to post my own experiences. A 92 SVX I owned had no AC for about 2 years. One hot summer day I decided I was going to get an interdynamics kit and charge it up. I charged it and clearly it was leaking from one of those compressor o-rings. I replaced the o-ring, charged it again, and the car had cold AC for the remaining 3 years that I owned it. I never evacuated anything.
