You most likely won't be able to buy this unless you have certification in recovery and charging HVAC equipment.

Get on  macsw.org  pay your'e $15.00,  take an open book test, get you're freon certificate and go buy some R-22.  It is that easy, I just did it last year and the certificate has not been refused by anyone.

Hi Robert,

The R-438A gas just happens to be Duponts brand and will work just fine.

I use 407-C and 417-A which are also direct drop in refrigerants for R-22.

According to my suppliers, there is enough R-22 around to last about 10+ years...

Another fact,  the price of a 30lb tank of R-22 is still lower then the replacement gasses...??..??

Things that make you go Hummmm!

Have a great day!

Is it true that the replacements are 10% or so less efficient than R22?

Thanks,
Ken

Hi Ken,

More like 5% but only when used in systems that they are not designed for Like R-22..

Hope this helps
