R22 v. 410A

The Refrigerant in your central air conditioning unit is usually R-22 or Puron (410A). Due to the Montreal Protocol, R-22 is in the process of being phased out. Puron, is considerably more environmentally friendly, and air conditioning and other energy companies are coming up with more environmentally friendly ways to cool our cities every year. The EPA, has a lot of resources on their webpage and even animations to help explain what the problem is. One of the reasons we are switching to Puron is to help decrease the size of the holes in the Ozone. The Epa's animation below shows the probable improvements.
