FAQ: 

Is there propane in R-32?: No, R-32 is pure difluoromethane. It does NOT contain propane.

Can you mic R-410A with R-32 or top off an R-410A system with R-32?: No - an R-410A system wasn’t intended to be charged with an A2L like R-32.

For residential unitary split systems, will R-410A compatible evaporator coils, air handlers and furnaces be matched with R-32 outdoor units?: R-32 evaporator coils and air handlers are required to match with a R-32 outdoor units. 

Will contractors need to be certified to use R-32?: It is not required, but it is recommended that contractors obtain training for the safe handling and transportation of Class A2L refrigerants.  ACCA, ESCO and NATE all provide safe handling and transportation training with certifications.  Refrigerant manufacturers also provide training.  Daikin provides live training options, VR training, and prerecorded content geared towards technicians and comfort advisors available at www.HVACLearningCampus.com. 

Can Contractors use the same tools and charging equipment with R-32?: If their tools are rated for use with Class A2L refrigerants and are non-sparking, they should be able to use them.  A separate set of hoses for each unique refrigerant is required to avoid mixing refrigerants. Existing gauge sets for R410A, R22, R407C, etc. can be used to measure pressures, but they may not have appropriate saturation temperatures for R-32 (and R454B).

Will current meters to find leaks work on R-32 or is there a new meter coming out?: Leak detectors for use with A2L refrigerants are now available.

Are R-32 pressures higher than R-410A?: R-32 has slightly higher pressures compared to R-410A, but they are very similar and therefore applied and used in the same manner.  Our quality and reliability testing has shown there are no discernable differences.
