From 1 January 2010 it became illegal to use virgin HCFCs like R22 refrigerant to maintain or service air conditioning equipment. As a temporary measure re-cycled or recovered R22 can be used until 31 December 2014, but costs may become high as it gets scarcer. From 1 January 2015 sales and use of all recycled or recovered R22 to maintain or service air conditioning equipment will be banned.
For other Companies who are still using R-22, Its time to replace them now before it last.
