DON'T allow your vehicle to be converted to a blend.  Blends are a mixture of refrigerants and considered a contaminated system by most reputable air conditioning shops.  We at Matt's, do not use blends.

DON'T allow anyone to install a sealant into you air conditioners sealed system.   Even if it does temporarily stop the leak,  it's not a permanent fix, and the damage caused by this sealant can and will destroy the entire system and make the system unfixable.  True professional air conditioning shops wouldn't consider putting that junk in there vehicles, why let them inject it into yours.

DO, Call Matt's Auto Service.
