Freon 22

You didn't look very hard ... by just entering "r22 replacement" in a startpage rearch box i got a bubch of hits . Here's one that looked good to me ...

"Terry Coombs" fired this volley in news:nquvpa$l3q$ snipped-for-privacy@dont-email.me:

Yeah... and there are a couple of "homebrew" refrigerants that come close-enough to serve, too.

This guy is one of those who DOESN'T search -- he just asks on a forum, and hopes someone will _give_ him the answer.

You can still get R22. Not cheap but it's still out there.

Yeah , but didn't they make it "illegal" to use it ?

Steve - getting r22 requires getting a license or hiring someone with a license; as you say, not cheap.

Thanks Terry. Do you happen to know of any suppliers of containers with less than a pound of rs-44?

Nope, you just have to be EPA section 608 certified to use it in a stationary unit. Free study guide, free test software. Take a $25.00 online test and you're good to go.

I did full 608 and 609 way back when they first came out. If you do A/C work it's best to have both because the rules are rather convoluted.

For instance if you need to work on bus A/C units, 609 covers R-12 and R-134a systems, BUT if it's using R-22 you need 608 because it's considered a high pressure unit and NOT a Motor Vehicle A/C unit, Even though it's in a bus!

If interested here is a company that does the testing
