Now that we are in a new year of greatly reduced supplies of new and imported HCFC-22, it is important to note that there is no ban on the use of R-22. You can use R-22 for as long as supplies last and you have well running R-22 equipment to service.
The entire furor at the beginning of the year over the refrigerant relates to, as I just said, new and imported R-22 because supplies were cut from 51 million pounds allowed in 2014 to 22 million pounds allowed in 2015 and heading to zero pounds allowed as of Jan. 1, 2020.
