finding a good shop that I would even trust
Like you after years of doing our own work,knowing how you want it done, it is a challenge .
Went thru this with my PT Cruiser. It needed a clutch and I had a shop do it.
loosened that connection.
When I picked the car up the A/C didn't work. They pulled a line loose when removing the tranny.
At my age now there are thing I just can't do anymore.

As I get older my motto is "make the call, write the check"
 
As my old work buddy James use to say: If you want a job done right, HIRE somebody. That was from probably the sorriest employee my company ever hired....lol
 
FWIW Check into getting a 30# cylinder... You'll need to see if a friend will hook you up since you need a license to buy the 30# but the savings is/was insane, 1# cans are $15-$20 Last year I bought a 30# cylinder it was $120... Looking on line I'm seeing $500+ for a 30# cylinder but unless things have changed dramatically I think that's places fishing for suckers...

Might be time I buy a couple more cylinders just so I'm well stocked...
 
Avoid "recycled refrigerant" if you can and get a cylinder of nitrogen for purging the system.

So I called my warehouse $335 for 30#... Not quite the bargain it use to be...
 
1. Never, ever, use refrigerant with a leak stopper or sealant.
Excuse my ignorance here…would you please explain why you say this? I see many refrigerants advertised with sealants. In fact I’ve used them before myself.

I'll send you my ruined robinair gauge set, that'll explain it all. Lol. First, because the 'sealant' will plug the orifice and/or condensor. And secondly, if you ever take it to be repaired proffesionally and they're worth a ****, they'll use a refrigerent tester before they touch it that looks for flammable gasses, and you guessed it, sealer. If it has either they won't use their machine on it as the sealer will plug it up.
I get it, all the parts places sell it like radiator stop leak, head gasket in a can, engine rebuild in a can, oil leak stopper, etc., so your average Joe sees no issue and it solves their problem, they think. If sealer(stop leak) is detected at one of our dealerships in a customer's system, everything, compressor, lines evap, condensor, etc all have to be replaced.
I know it's more info than you wanted probably, but I don't know how else to explain it. I apologize.
I see 40 cans of refrigerant with sealer and 6 cans of plain ole 134 on the shelves and I just shake my head. These parts places don't give 2 shits if this stuff ruins anything because they are in the parts business.

Thank you. That’s good info to consider, especially considering making the investment in my own equipment myself.

Dedicated vacuum gauge that reads in microns is a must. That pump will give you the deep vacuum you need but a dedicated gauge is the only thing that can confirm microns. The compound gauge on the low side of the gauge set confirms that a system is in vacuum, but does not read accurately enough in the low ranges that you need to confirm that all noncondensibles have been removed from the system.

I do that by shutting off the gauges and letting it sit for 5 or 10 minutes, if the gauge moves towards zero, I pull it down more and repeat until vac holds. I know it's not 'precise' but it works. Your way is a neat alternative but I do so little ac work I can't justify it.

I need to work on the A/C systems for at least two different cars. I am tired of (a) leaving my car with unknown shops and (b) paying big dollars for A/C work. So I want to get the tools I need so I can work on A/C repairs myself. Previously, I have just shoved cans of R134a into the system with one in-line gauge. I need to step up my game.

Can you help me get a good list for the A/C tools I need?

I went quickly to Summit Racing to spec out a couple of things.
First, I need a good set of gauges. Something like this? I like that it has a case to keep it neat and tidy when I don't use it.

Then, I guess I need a vacuum pump. Like this?

Obviously I need cans of R134a (mine has been converted).

Any feedback on my tool choices? Additions? Replacement? Subtractions? Any feedback is appreciated!

Thanks,

Hawk
