Unfortunately, releases of HCFCs deplete the Earth’s protective ozone layer and contribute to climate change.  \nR-22 is an HCFC refrigerant that is often used in air-conditioning equipment. To protect the Earth’s protective ozone layer, the United States is phasing out R-22, along with other chemicals.  \nAs the United States phases out refrigerant R-22, you will need to make informed choices when servicing, repairing, or replacing an existing air-conditioning unit or when purchasing a new unit. EPA has banned the manufacture of new equipment that contains R-22 . As a homeowner, you need to consider and balance several key factors in your decision to purchase a new unit, such as energy efficiency, performance, reliability, cost, and the refrigerant used.  \nThe lengthy phaseout period allows you to replace your air-conditioning equipment that contains R-22 when you normally would, for instance if it becomes old, inefficient, or ineffective. Realizing that supplies of R-22 will become more limited and that the price may increase should also be factors. In the meantime, R-22 remains available for servicing equipment made before 2010.  \n\n| Availability and Cost of R-22 |  |  |\n| --- | --- | --- |\n| R-22 is a refrigerant that is often used in airconditioning equipment.\u003Cbr>Because R-22 depletes the ozone layer, production and import was further limited in 2010.\u003Cbr>In 2020, R-22 will no longer be produced or imported After 2020, only recovered, recycled, or reclaimed supplies of R-22 will be available. |  | . |\n| The production (not use) of R-22 is being phased out You are not required to stop using R-22 air |  |  |\n\n.  \nconditioners nor to replace existing equipment.  \nThe phaseout period provides time to switch toozone-friendly refrigerants when you normally would replace your air conditioner.  \nIn the future, R-22 supplies will be more limited and costs to service equipmen","cbCainukVw5oPkMx","https://ap.wps.com/l/cbCainukVw5oPkMx","pdf",232447,"English","# HCFCs and the Ozone Layer\n## Phaseout of R-22 and HCFC-142b (R-142b)\n## What you need to know when servicing or replacing an air conditioner\n## What are HCFCs and R-22?\n## Availability and Cost of R-22\n## Servicing Systems with R-22\n## Buying a New Air Conditioner\n## Alternative Refrigerants","[{\"question\":\"What are HCFCs and how do they affect the ozone layer?\",\"answer\":\"HCFCs (hydrochlorofluorocarbons) are mainly used as refrigerants.
