The FBI, the Environmental Protection Agency (EPA) - Criminal Investigation Division, and the U.S. Department of Transportation - Office of Inspector General are conducting an investigation into a flammable “refrigerant” sold as Super-Freeze 22a, Super-Freeze12a, Super-Freeze 134a, Enviro-Safe 22a, and R134a. These products have not been submitted to the EPA for review as alternative and accepted refrigerants.
If you have purchased any of the above refrigerants and/or received a letter notification from the FBI, you have been identified as a possible victim who may have unknowingly purchased flammable refrigerant.
This refrigerant product had been marketed as a drop-in replacement, second generation, non-ozone depleting hydrocarbon refrigerant. The target consumers were home owners and do-it yourselfers. The product could be purchased online and over the telephone by anyone; a refrigeration license was not required to make the purchase.
If a flammable refrigerant has been installed into your air conditioning system, call a licensed heating and air conditioning professional, and do not attempt to service the system yourself. If you suspect a leak, call your local fire department immediately. The flammable refrigerants are not believed to contain the “rotten eggs” smell typically associated with liquefied petroleum gas or propane.
