R-22 (freon) discontinued

R-22 (freon) refrigerant is no longer in production due to environmental impact and has been replaced with 410a (puron) the new refrigerant. What this means for you as a customer is that although R-22 is still available there are ethical limits for its use, so the epa urges us to repair leaks before large amounts are added. http://www.epa.gov/ozone/title6/phaseout/22phaseout.html
