R-32 (difluoromethane) is a single-component HFC refrigerant that has become the global standard for mini-split heat pumps and is gaining share in light commercial rooftop applications. With a GWP of 675 - 68% lower than R-410A - it offers significantly lower climate impact while delivering superior volumetric capacity (meaning smaller components and charge sizes). Classified A2L (mildly flammable), R-32 requires installation and service in equipment specifically rated for it. Virgin sealed, AHRI-700 compliant, same-day ship from Houston.
R-32 is a single-component refrigerant; R-454B is a blend of R-32 and R-1234yf. R-454B has a lower GWP (466 vs 675) but R-32 is simpler to recycle and is more widely adopted globally.
Only if the equipment is specifically designed for R-32. They are not interchangeable; R-32's A2L safety class and different operating pressures require purpose-built systems.
Yes - under the EPA SNAP program, R-32 is approved for use in residential AC and heat pumps installed in equipment designed for it.
