Repair Industry Group Warns Motortists of Flammable RefrigerantsSACRAMENTO, Calif., Jan. 15 -- A number of chemical blends masquerading as Freon could cause major damage to vehicles, and the Automotive Service Councils of California is urging motorists to make sure they are being sold a refrigerant that has been approved by their vehicle's manufacturer. While many of these chemical blends have been given clearance for use in home and commercial refrigeration systems, they haven't received approval from the U.S. Environmental Protection Agency for use in passenger vehicles. They are being marketed as less-expensive alternatives to R-12 (also known as Freon) and R-134A, the industry-standard refrigerants. The ASC, an independent repair industry association, has so far only endorsed the use of R-12 and R-134A. "Many chemical-blend products use propane, butane or other flammable gases," said Mike Mahneke, president of ASC. "They have the ability to leak out of the system and cause an under-hood fire, or a hose can burst or an O-ring can leak at the evaporator and the flammable refrigerant will seep into the passenger compartment. The potential could be serious." Mahneke also warns motorists that these chemical blends can cause compressor failure and other refrigeration system malfunctions, and the use of any other refrigerant not approved by the vehicle manufacturer will void the warranty on the air conditioning system. The Automotive Service Councils of California is also alerting its member repair facilities to beware of vehicles that have been filled with one of these chemical blends. When a repair shop fills a vehicle's air conditioning system, by law it needs to capture the refrigerant currently in the vehicle into a dedicated recovery system. Refrigerants must not be mixed in a recovery unit. These blends can cause thousands of dollars in damage to an expensive recovery system, Mahneke said. Mahneke, who owns and operates a garage in Santa Barbara and who is a certified master automotive technician, said he had to purchase a $2,000 "sniffer" to identify the type of refrigerant in each vehicle so he wouldn't contaminate his recovery system with a dangerous chemical blend. "Until these chemical blends get approval from the manufacturers, our recommendation to Wages throughout the state and for vehicle owners is to use the approved, industry-standard refrigerants, R-12 and R-134A," Mahneke said. The Automotive Service Councils of California is an association of 2,700 independent automotive repair shops and related businesses. For more information, call the ASC at 916-924-9054.
