The substitutes will work, but they have advantages and disadvantages. You can't add a substitute to existing R12... have to vacuum it all out and replace with the substitute. They are usually blends, which means if you do have a leak you have to vacuum out and start over (except for Jim C. who blends his on the fly!). The blends are also usually flammable, which some people use as a negative point. IIRC, either R134 or R12 is flammable anyway so it doesn't really much matter. The blends also stop working above a certain ambient temperature (~100)... so if it is really toasty where you live they won't work. The replacements *are* cheaper than 12 though... Just get your EPA609 certification ($15, online, open book test) and get two or three cans on ebay for about $15 a can. Really not all that more expensive than R134. I have no vested interest in maintaining an AC servicing monopoly... I just live in the south and like cold A/C!!
