INDIANAPOLIS (May 24, 2012) – Federal regulations have turned what was a commonly available air conditioning system refrigerant into a scarce resource. And that may make a lot of homeowners sweat this summer.
The U.S. EPA’s Montreal Protocol included a provision to phase out a refrigerant called R-22 because of its harmful effects on the ozone layer. That coolant is to be completely phased out by 2020 and replaced with a non ozone-depleting coolant, R-410A. Some small amounts may be available beyond that date for units that remain in operation.
Manufacturers stopped making air conditioning systems and equipment that use the old, harmful fluid two years ago.
Newer units cannot use the R-22 refrigerant. Ninety percent of the old refrigerant is expected to be out of use out by 2015.
Older units can still be serviced with R-22 refrigerant or R-22 retrofitted refrigerants such as R-427A. They cannot safely operate with the new R-410A coolant.
“But there’s a lot of hot weather between now and then,” says Angie Hicks, founder of Angie’s List, which offers consumer reviews on local service companies. “And consumers with older, leaky and otherwise failing air conditioners may be paying a lot to keep cool."
Some R-22 coolant is being produced but only under allowances from the EPA as it moves toward phase-out. Because of this short supply, prices for it have soared and HVAC specialists are harvesting remaining fluid when they replace older units. The leftover coolant can safely be re-used in those units, but isn't to be used in other units without being properly cleaned and certified by the EPA.
Refrigerant leaks are a common problem with air conditioners. Over a couple of years, most units will lose a pound or two of the eight pounds of coolant typically needed to keep the machine pumping chilled air throughout your home.
“The scarcer R-22 becomes, the more expensive it will be,” Hicks said.
Highly rated HVAC companies tell Angie’s List that the cost for the R-22 coolant is now $175 for the first pound compared to $30 as recently as two years ago. Prices fall to $90 for each additional pound now compared to the older $10 charge. Homeowner opting for repair should be prepared to also pay additional costs to cover service, labor and any other parts necessary.
“Some homeowners will need to think seriously about replacing their units with newer ones that use the new coolant,” Hicks said. “This isn’t entirely bad news. The newer units are more environmentally friendly and more efficient. Heating and cooling accounts for 54 percent of your home’s yearly energy costs, so long-term savings can really add up.”
Hicks advises homeowners to talk to a reputable heating and cooling system expert before making any decisions about retrofitting, repair or replacement. Technicians who handle refrigerant are required to earn EPA certification before working with the fluid and should be happy to discuss your home’s needs. HVAC companies should be up-to-date on these issues and happy to educate consumers, she said.
“This is a conversation you could have if you’ve scheduled the annual inspection your unit needs anyway,” Hicks said. “A reputable technician can give you great advice on what option is best for you and will also point out available rebates and other cost saving options that might be available”
