AC Smoke? Can you use a EVAP smoke machine on AC? 

I have did this with a regular Snap-On smoke machine, I Did not change the oil like you did, I have found evaporators leaks in the dash doing this very helpful. I simply feed the smoke line into the yellow feed line into the gauges. After I am done I let the vacuum pump run for a while to vacuum out the old residue etc. My Ac still works in my truck years later after I Did this so no bad side effects.

Awesome video brother. I was thinking about trying this myself and was wondering if anyone else has done it already and I see that you have. Great work. I will probably try this myself and I may change up a thing or two but this was awesome. Thank you!

I do a lot of a/c work on semi truck and heavy equipment. So far no call backs. After using the smoke method. Thank you for the informative video.

AWESOME IDEA WILL TRY THIS AND AS ALWAYS THANKS FOR SHARING.

I wonder if u used oil with dye in it could u you see smoke better with black light???

Hi Chad, is some oil with dye color like green or red color? . I like your videos a Lot and more when you show tools or diagnóstic. 🙏👌

A new compressor? Are you sure about that? Could be an inexpensive seal only at compressor.

Aren’t you worried a little about smoking off label oils like pag 46? Ok to breathe? I mean… “the pioneers take all the arrows”, ya know?

Y did U change oil, doesn't make sense.

Traditional leak detection is to pump sysdtem 1st with a sniff of system refrigerant 2nd back up with nitrogen and check system at 50 psi then at 250 psi . Check with electronic sniffer and bubbles . Check all o rings, compressor seal ,evaporator drain and vent with fan on . UV dte will pick up leaks but evaporaters are hard to detect some times evident in the drain but not always . CO2 leak detecting is also done but requires its own set up $$$$ [testing must be done at 250psi ] Your Standard smoke test unlikely to pick up small high pressure leaks particularly in evaporator. Just buy a nitrogen bottle and a good brand sniffer 500-1200$

I think if you're doing this is a good idea to wear a mask, that smoke is probably very toxic.
