While R-22 remains available for servicing equipment made before 2010, it is important to know that supplies of R-22 will become more limited over time. Contractors can send refrigerant they remove from an air conditioning system to a reclaimer who will reclaim the refrigerant to restore it to a purity level that meets AHRI Standard 700. This reclaimed refrigerant can be used again to recharge R-22 air conditioning systems. This will help extend the supply of R-22.
