Since January 2010 in the United States, use of R-22 is no longer permitted in the manufacturing of new HVAC units. That is because R-22 has proven to be harmful to the environment due to its ozone-depleting properties. Instead, all newly manufactured air conditioners and heat pumps use a more environmentally friendly refrigerant called R-410A.
