New residential air conditioning units can only use R-410A, but older units running R-22 still exist. Talk to contractors about retrofitting R-22 residential A/C units with Genetron® 422D or 407C.
Supplies of R-22 are set to be reduced every year until 2020 when R-22 will no longer be available. Review Honeywell’s non-ozone-depleting alternatives to determine which R-22 replacement is right for you.
