Has anybody here used a do it yourself AC charge kit?

I just got the car running (Code 57 Fathom Green thread) and want to get the Vintage Air AC system going. I didnt install the rest of the dash just in case there was a leak/problem. So the AC install is holding me up.
I was at the local Carquest getting some stuff and noticed several AC charging kits selling for around $35-40 bucks.
I want to try it myself so bad but thought I would run it by TC first.
Anybody here recharge a new aftermarket AC system? What were the results/problems?

Either get an A/C manifold set, the gauges and hoses made for the fittings on the lines, R12 is a screw on fitting, R134A is a quick disconnect, and get a rough vacuum pump and evacuate the system for about an half hour. Shut off the valves and see if it holds a vacuum, overnight would be good.

If you have a leak and does not hold a vacuum, pressurize with nitrogen to 150 PSI and Snoop the bejesus of all the fittings and hose crimps. See bubbles, it may take about 30 minutes for minute leaks, fix it.

Evac again. Then add freon of choice. Set a box fan in front of the car to aid in cooling of the condensor and radiator. If an orifice system, set evap pressure for 30-32 PSI.

Or get your A/C buddy over to help.

Well...I guess I'll be taking the car to get the AC system evacuated and charged. Sounds like this job is like many others I have considered/tried. If you do it once, (IE headliner) it takes time and patience and the second time you do it, it would be perfect. This one is too important to not get right the first time.

Recharge is easy. But I think I would take it to a pro for the initial setup.

Yeah, a shop with the correct system would be best. It needs to be absolutely free of moisture which you need to proper system to do.

Go some place that can do it.
You MUST evacuate the system then charge it to its proper charge weight. Cans are at best Guesstimates. An AC shop can put in the freon to the exact ounce.

AC isn't for the DIY'er.
