Hey all,

I posted a couple weeks ago about how my low side cap had a leak and leaked out all my refrigerant....

I got some of the enviro safe refrigerant (I know some of you dont like this, I understand and not really looking for comments about it being a bad idea )

It states that a 6 ounce can is equal to 18 ounces of r-12. My capacity in my system is 2.6 lbs. so I ordered 4 cans so I could have some handy for recharges if needed.

I hooked up my low side, and didnt have the correct connector for high side so left that unhooked. Started the car, started charging the empty system, and it sounded like the compressor engaged, and the system was accepting refrigerant. All seemed good.

After the 2nd can, I checked the cabin to see if it was cooling, it was not. I still had a 10 psi reading on my low side so I went with another bottle. Did that one, still showing low pressure and could not tell a huge difference on cooling. I was wondering if the claims of using so much less were wrong and did the 4th can because my pressures still showed low.

After the 4th can and no cooling, I started to freak out. I took off the bottle and didnt have the valve turned off, thought it would spray all over me, but there was suction! I walked away from it for a while to research.

Upon research, I found that suction means the compressor is not fully engaging, and was thinking I really really overcharged this thing. Went out to go get a high side fitting, and for the heck of it turned on the AC, and it was very cold!

I hooked up the low and the high side, and at a little over idle, had 28 psi low side and 150 high side. So it seemed a little undercharged, and it was blowing cold.

So my two questions that are nagging me are:

1. When the bottle was off, there was a few seconds of suction, so obviously the system was sucking in air. I know air is not good to have, but is that serious enough to empty the system again and re charge?

2. How the heck could I have near ideal pressures for low and high side after 4 of the 6 ounce bottles? According to the enviro safe website, that is the equivalent of 4.5 pounds of r-12 in a system that has a capacity of 2.6 pounds.

Thanks for any help.
