The use of such a flammable refrigerant in a home or building can create a serious fire and explosion risk as heating and air conditioning systems typically involve combustion flames and spark igniters that are potential ignition sources. A leak in the refrigerant system could bring flammable vapors in contact with an ignition source, with potentially fatal consequences, stated the HRAI.

“With the air conditioning season nearly here, Canadians need to be aware that flammable refrigerants used in home or business air conditioning systems can create the potential for a serious explosion and fire, which could result in injury or death,” said Warren Heeley, president, HRAI. “It is time government authorities, including provincial fire services, take action on this potential hazard.”

In their fire marshal message, the HRAI shared that, in addition to the potential for fire and explosion, the refrigerants used in these DIY kits are not approved for use in air conditioning systems already installed in the home or business and use of such gases could cause environmental damage if the existing refrigerants in these systems are not properly recovered. Improper mixing of the existing refrigerant with the DIY hydrocarbon refrigerant could also have a negative impact on the operation of the air conditioning system, potentially causing added repair or replacement expenses to the home or building owner.

Prior to purchasing hydrocarbon refrigerant DIY kits, home and business owners should be fully aware of the potential hazards and liability of using hydrocarbon refrigerants in air conditioning systems.
