Service considerations
Do not mix R22 with alternative refrigerants. A conversion, where appropriate, needs a system-specific procedure and a review of components and lubricant compatibility.
Compatibility & handlingU.S. production and import of new R22 were phased out in 2020. Existing systems may still be serviced using eligible existing or reclaimed supplies. No virgin or reclaimed status is implied by this description.
