R-22 refrigerant is on the way out. As early as 1974, scientists suspected that HCFCs, or hydrochlorofluorocarbons, of which R-22 is one, were bad for the environment. After Joseph Farman and his colleagues published findings in 1985 about the alarming decline of ozone levels, it became clear that R-22 and similar chemicals were playing a role in this depletion. The first Montreal Protocol was drawn up, beginning the slow phase-out process. While the total ban isn’t until 2030, the effects of the gradual ban are already here.
As of 2010, all new air conditioning equipment must use R-410A refrigerant. Prices of the old refrigerant have risen dramatically since this ban on production of new equipment using R-22. In some cases, the cost of service calls for old refrigerant have tripled. This trend will only continue as R-22 steadily becomes more scarce and therefore more expensive.
During the changeover
Equipment manufactured to use R-22 cannot use R-410a. Since the parts of the air conditioner must match in terms of the kind of refrigerant they use, homeowners with older equipment will perhaps choose to replace the entire system, rather than just the malfunctioning part, since R-22 is becoming shorter in supply. Even though R-22 will continue to be made for older equipment, the price will continue to rise, as it grows more scarce while being phased out.
Long-term maintenance costs are the biggest concern if you decide to repair a system that uses R-22. Keep in mind the age of your current system and whether it is still under warranty. If your old system ever needs heavy maintenance, your money may be better spent with a new system designed specifically for R-410A. Professional advice will save you money and energy costs during the refrigerant change-over.
