Is it a good idea to replace the freon in a typical home AC unit with an Enviro-Safe type of substitute?

and when you take out the old stuff, what do you intend to do with it? Home AC units do not typically leak the way auto units do, simply because the home unit is sealed. Auto units have an exposed pulley shaft that always leaks a little refrigerant so cars are always putting refrigerant into the air. Homes, however, do not. Just leave it alone until the AC unit fails, then replace everything. Pretty sure there is a leak so that takes care of the 'what to do with the old stuff' issue. Want to fix the leak and heard about the Enviro-Safe products (google for info) and supposedly it is comapatible with all units (even on top of R-22) and runs at a lower pressure which not only puts less stress on the unit but results in a 20-45% drop in electricity consumption, which is very enticing to me since I live in Florida. Your thoughts? ==Discussion== The stuff you are talking about is probably R-410 which is the new blended refrigerant. This uses a different oil than R-22, so if you make the change you need to blow the current refrigerant lines. 410 runs at higher pressure so I do not know which replacement you are talking about.
