The most common substitute for R-22 freon is R-410A, which is a hydrofluorocarbon (HFC) blend that does not deplete the ozone layer. Other alternatives include R-422B and R-438A, which are designed to be retrofitted into existing R-22 systems. These substitutes are more environmentally friendly and comply with current regulations aimed at reducing greenhouse gas emissions. However, it's important to ensure compatibility with the existing system before making a switch.
