To help protect the ozone layer, the EPA has mandated that the production of Freon be stopped by January 2020. The good news is that new air conditioning systems made since 2010 no longer rely on Freon. Most newer AC units use a refrigerant called R410A, or Puron.

Do you need to change R-22 refrigerant to Freon?

According to the EPA, this reclamation and recycling should ensure that existing supplies of R-22 will last longer and be available to service a greater number of systems. Existing units using R-22 can continue to be serviced with R-22. There is no EPA requirement to change or convert R-22 units for use with the new non-zone-depleting refrigerants.

What happens to the refrigerant in a condenser?

Forever so long as there are no more leaks? Are leaks inevitable?” For context, this customer’s parents had a slow refrigerant leak in their AC system. These are great questions.
