Thread: A/C PRO recharge kits

It is finally warming up here in MN and we can put an end to the Brrrrr!! thread. Has anyone used the A/C Pro recharge kits? I see ads on tv and the kits are in current Auto Parts sale fliers.

Thanks.

I have used that stuff on two cars and been pleased with the results.

I think I used the Ez Chill stuff.

I just used it on mine and it worked fine.

I use the cheapest cans of r134a I can find. I just got some for $5 a can. It all works the same. If you have to add to your system though you have a leak somewhere

If you suspect a leak, get some refrigerant dye and put a few drops in the end of the connector before hooking it up. If it starts getting warm again, you can use a black light to spot where it's leaking. Check with a black light before you try though, you may need to rinse the lines and stuff down as other things can glow under the light.

Those things work great as long as the leak is small, it kept my 05's AC running by adding a can once a year, but don't bother with any that contains stop leak. It shouldn't do any harm, but it won't stop any leaks.

Now if you want like, as cold as when the car was new, just buy a gauge set from Harbor Freight (they're pretty cheap) and rent a vacuum pump. You can do a professional evacuation and recharge surprisingly easy.



This dude shows how easy it is. As long as you use the correct weight of refrigerant, nothing will get you colder AC than that. Replacing the accumulator wouldn't hurt either.

best bet your low side port valve but yeah all 134a is the same. I love fixing ac systems its so freaking easy

Thanks for the info paedbo, I just learned some useful info! I'm doing basically an AC overhaul later this month, so I'll definitely keep all that in mind.

Can't wait for some ice cold, reliable AC, I haven't experienced that since I got my 05 used three years ago

Black death?

your talking about when you mix r12 with r134a yeah it makes a black sludge and kills the compressor.



EDIT: its the oils from r12 and 134a mix and make it

Nylog, I've never heard of the stuff. Definitely can't hurt, I'll be replacing just about every o-ring anyways. I'm going to guess you've done quite a bit of AC work

don't have to necessarily mix oils. poor lubrication, and on compressors like the fx15 the Teflon rings disintegrate turning into a fine powder. Mixed with hot oil and refrigerant and tada! Black death caked all over everything. No use trying to flush. You may be able to save the evaporator otherwise its a firewall forward replacement of everything. Put a new compressor back in a system that suffered black death and it will not survive long either.

Nik -12937 blue nylog by the way. red is is harder to work with. Btw I am a licensed mvac technician all though I haven't worked in the field for a long time.


here's another interesting thing I found I have not used this product tho.

I had a sneaking suspicion you were, a majority of people (including me) have a pretty limited knowledge of AC systems past their basic design.

I'll just order some tomorrow to make sure I don't mix them up, it's pretty cheap for how helpful it could wind up being.

I think I'll test out those oil checkers too while I'm at it, can't argue with $7.50 after shipping. I know for a fact my system is pretty done at the moment, though it still works for a week or so if you add some freeon, so I can test one knowing it should come up bad. Another tool to make sure I get the system as close to its condition out of the factory. Not having AC is actually even crappier in the winter months (in my opinion) while living in PA. I can stand pretty hot temperatures without much complaint, but it's so difficult to defog the windows in cold weather without a functioning compressor.

The compressor doesn't run if it's under 36° anyway
