Don’t Forget The New A/C Refrigerant Mandate – Now That Summer is Near..!

What is the Montreal Protocol and why is it important?

In 1987, world leaders met in Montreal, Canada to discuss the effect of chemicals on our Ozone Layer. As a result, an international environmental agreement, referred to as “The Montreal Protocol,” established requirements that began the worldwide phase out of ozone-depleting CFCs (chlorofluorocarbons). These requirements were later modified, leading to the phase out in 1996 of CFC production in all developed nations. In addition, a 1992 amendment to the Montreal Protocol established a schedule for the phase out of HCFCs (hydro chlorofluorocarbons). HCFCs are substantially less damaging to the ozone layer than CFCs, but still contain ozone-destroying chlorine. The Montreal Protocol, as amended, is carried out in the U.S. through Title VI of the Clean Air Act, which is implemented by Environmental Protection Agency (EPA).

An HCFC known as R22 has been the refrigerant of choice for residential air conditioners for over 40 years. Unfortunately for the environment, releases of R22 that result from Freon leaks contribute to ozone depletion. In addition, the manufacturing of R22 results in a by-product that contributes significantly to global warming.

What is taking the place of R22 refrigerant?

The replacement refrigerant is referred to as 410A (or Puron) and is a Polyolester (POE) based refrigerant, as opposed to the mineral based oil used in R22 systems. In addition, 410A contains no HCFC’s and is not harmful to the environment or ozone layer if it leaks from the system.

Will there be R22 refrigerant available to repair existing air conditioners after 2010?

Yes. The phase out of R22 production allows for the manufacturing of R22 refrigerant through the year 2020, strictly for the use of servicing existing equipment. After 2020, the servicing of R22 systems will rely on recycled refrigerants and it’s expected that reclamation and recycling will ensure that existing supplies of R22 will last longer and be available to service a greater number of systems beyond 2020.

Can you install an R22 system after 2010 and will R22 equipment be available?

Yes. Manufacturers are allowed to sell existing inventory of R22 equipment after January 1, 2010, but will be prohibited from manufacturing equipment containing R22 refrigerant after that date. “Reliable” sources at several of the major manufacturers of residential air conditioners believe R22 units will be in short supply after Q2 of 2010. ORHP will install R22 equipment when available after January 1, 2010.
