With R-22 scheduled to be banned for use in new equipment by 2010, manufacturers of air conditioning equipment stepped up the changeover of product lines to R-410A. There were questions about higher operating pressures and a learning curve with 410A, but training programs dealing with such matters were on the increase in 2004.
Production of R-22 for the aftermarket can continue until 2030, but supplies of the refrigerant will be gradually phased out.
