R-410A Pros and Cons

October 1st, 2009

R-410A is a blend of various refrigerants and, for now, is considered by the EPA to be a non-ozone-depleting refrigerant. While R-410A was invented and patented by Allied Signal (now Honeywell) and Honeywell continues to be the leader in 410A capacity and sales, other producers around the world have been licensed to manufacture and sell the product.


  • R-410A is considered to be safe for the environment.
  • Currently, R-410A is available to purchase at prices comparable to R-22.
  • R-410A is relatively safe to store, use, and transport when handled by properly trained technicians.



  • Used at much higher operating pressures than R-22.
  • Because R-410A is a blend of refrigerants it cannot be recycled (unlike R-22, which can be recycled and reused numerous times).
  • R-410A designed systems require thicker walled tubing, and compressors capable of withstanding the higher pressures of R-410A.
  • R-410A’s polyolester (POE) oil is more susceptible to moisture which can produce acid buildup within the refrigerant circuit.
