The U.S. Environmental Protection Agency (EPA) announced its final phasedown schedule regarding production and importation of HCFC-22 on Oct. 16. The order calls for an immediate drop from 51 million pounds allowed in 2014 to 22 million pounds beginning Jan. 1, 2015. Subsequently, 18 million pounds of new and imported R-22 will be allowed in 2016, 13 million pounds in 2017, 9 million pounds in 2018, and 4 million pounds in 2019. No new or imported R-22 will be allowed in the U.S. on or after Jan. 1, 2020.
Looks like I am going to buy more on Tuesday, though I rarely use R22, mainly on myself and family and friends AC. Most everything I do uses 134 or 404.
You can Always use Hot Shot as a replacement, but you cannot MIX them, it must be evacuated and then recharged and it is undr $300 for a 25lb Bottle.
I stand corrected. Must have been R-12. Been a long time since I worked on refrigeration systems.
