Refrigerant transitions, such as hydrofluorocarbons (HFCs) replacing chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), get all the press.
And as hydrofluoroolefins (HFOs), hydrocarbons (HCs), and natural refrigerants are set to replace HFCs, their often-overlooked partners — lubricants — are rarely mentioned. As the industry prepares to adhere to government-
mandated refrigerant transitions, one question is repeated over and over: “Can I use my old lubricants with
new refrigerants?”
