Repair or Replace?
Considering the options in air conditioning refrigerants

R-22 equipment? Or do they go ahead and purchase the new, more efﬁcient and more costly R-410A units?
An older R-22 unit is being hauled away to make room for a new R410A unit.
ow that the United States is dramatically reducing refrigerant R-22 production and banning the production or import of any air conditioning equipment ﬁlled with R-22, retail store maintenance professionals have several factors to consider when their stores’ air conditioning equipment breaks down. Should they authorize repairs on a unit that uses a coolant that may soon become scarce or extremely expensive? Do they make the repairs and hope for sufﬁcient supplies of recycled R-22, or rely on “drop-in” refrigerants that can work with the
R-22 was the choice of air conditioning refrigerant in the U.S. for more than four decades. But as concerns grew over ozone layer depletion, many governments, including the U.S., agreed through the Montreal Protocol to ban the production of ozone-depleting chloroﬂuorocarbons and hydrochloroﬂuorocarbons (like R-22). In the U.S., the CFC and HCFC ban is enforced through the Clean Air Act, which requires a phased reduction in R-22 production and importation [see chart on page 39: HCFC (including R-22) Phase out Schedule]. As of Jan. 1, 2010, the law required a 65 percent reduction in R-22 consumption and banned the manufacture or import of any new equipment loaded with R-22 as a refrigerant. But there is a loophole in that law. “The loophole said that manufacturers could build components for R-22 equipment but couldn’t build pre-charged R-22 equipment. Some manufacturers are taking this to mean that they can actually build condensing units dry, with no refrigerant in them at all—but they are designed to be used with R-22,” said Ron Prager,
