R-410A Refrigerant

R410A - A chlorine-free refrigerant that meets the U.S. EPA's newest, most stringent environmental guidelines. January 1st 2020 R22 was officially phased out in US and R-410A has replaced R-22 as the preferred refrigerant for use in residential and commercial air conditioners in United States. R-410A was invented and patented by Allied Signal (now Honeywell) in 1991, later R-410A was successfully commercialized in the Air Conditioning segment. Unlike R22, R410A does not contribute to the depletion of the ozone layer.


What is the difference between R22 and R410A refrigerant?

  • R410A is better at absorbing and releasing heat than R22, making it more energy efficient to use.
  • R-410A allows for higher SEER ratings than an R-22 system by reducing power consumption.
  • R-410A cylinders are colored rose.


Can I replace r22 with r410a?

R22 refrigerant and its HFC (hydrofluorocarbons) replacement R410A are totally incompatible. Your existing condensing unit and cooling coil are not suited to the new higher pressure refrigerant. R-410A cannot use R-22 service equipment because of higher operating pressures (approximately 40 to 70% higher).
