DIY R12 to R134a conversion

[Tuck]

I did this two weeks ago and so far, so good. I got a pressurizied can of flush, a filter/dryer, a blister pack of o-rings, two cans of R134a and a bottle of PAG oil to do the job from AutoZone. I already had a vacuum pump. I removed the compresser and drained the oil before replacing it with the PAG oil. Then I flushed the system, replaced the o-rings, and filter/dryer. Pulled a vacuum on the system and after seeing there were no big leaks, charged the system and was ready to go. BTW one of the cans of R134a had a leak stop in it and the other had a leak dection dye.

Why do I have a vacuum pump handy? I live in Florida and every time I took a car to get the A/C repaired it was $600. The pump was $400 @ Grainger.
