Doing my AC now.
Just need new lines made now.

Where are you getting your lines made?

The '05 Avalanche blows colder than this Jeep I just worked in. I dunno man. I charge the systems up using my gauges, watching pressures and keeping a big fan in front of the vehicles blowing on the condensors while running the a.c. on high max during Freon insertion.

Although, the Avalanche hasn't been messed with since factory.

Would you say this is an accurate table? This is what I used when measuring my high/low side pressures while charging. I also had a fan blowing on the condensor while charging, but it's possible I didn't have a big enough fan blowing enough air. I did use hot (boiled) water to dip the freon can into to help "boost" the charge going into the system when the can started getting frosty.

Friend is sending me to a guy about a 1 mile from my shop they use. Don't remember the name of the place off the top of my head.

That chart is pretty close to the ranges I am seeing on my gauges as well, with ambient temps at about 95* in the garage at the time of filling.

I usually just hold the cans upside down and only crack the valve at the manifold alittle, letting the freon go in slowly, usually takes about 4 minutes or so to empty a can. Also as I think someone mentioned earlier, once the can top is punctured, crack the can line at the manifold a bit for a second to purge out any air in the yellow line, crack it till freon comes out.

Good deal, that's exactly what we did (bleed the air out of the yellow line prior to opening manifold). I'll just have to settle for what I'm getting. It's decent, and maybe a small electric fan would help (to push air through the condenser when at idle and in traffic).
 
Went by TRM a out hoses. They have to pick up some ends. Should have hoses tomorrow or Friday.
 
Hope you get it dialed in after all this work.

I went the route no one said would work and used evirocare? It's propane/LPG in AC cans with a fitting, been blowing cold in my Suburban for 2 summers, no need to flush and change oil, cheaper the R134a, mixes with all oils and r12 and r134a. To good to be true but still working!

Supposedly it is what is used in Europe, we are stuck with Dupont lobbying of goverment to mandate their product... :dunno:

Was close to 100 here yesterday, vent temps was 34f and I had to turn down AC on highway... in a Suburban!
 
Didn't do a writeup, I had been reading about it and found a box of this at a garage sale and bought it. Had a little leak at a shrader valve so I used my old R12 recovery machine to evacuate the system, fixed the valve, used the vacuum pump and went to rechare when my R12 Recovery unit sprang a leak and I lost all my R12 I ended up using it...

Nothing specail, it's just like any other AC service except when charging the pressures are lower. Go by vent temps. They are a little lower at idle sitting still.


Brrrrrrrrrr! It was only 94f here yesterday and I was cold!
