What is the difference between freon and puron?
R-22 (commonly referred to as freon) is an HCFC which means it uses a mineral oil and contains fluorcarbons or ozone depleting elements. Because of this, R-22 is being phased out. By 2010, HVAC manufacturers will no longer be allowed to produce an R-22 based air conditioner. Supply of R-22 will be reduced by 65%, but the refrigerant itself will be around to service existing units at least until 2030. R-410A (commonly referred to as puron) is an HFC which is a refrigerant blend that uses a synthetic oil and contains no fluorocarbons or ozone depleting elements. Practicing proper refrigeration techniques on the installation of R-410A based systems becomes more critical.
