Will the Cryo-Seal people warrant against any damage that their product produces. I'll bet not. Why would they bad mouth something they are trying to sell you. That's a basically poor business practice. If you try to visualize the inside of an A/C system, get a mental picture of expansion valves with tiny orifices, reed valves in a compressor, the small passages in the evaporator, capillary tubes and the like. I'm a cheapskate when it comes to finding the least expensive way out of a problem, but guess what, if this stuff really worked as advertised, then all the HVAC shops would go out of business. Find the leak and fix it right. This may be costly or it may not, depending, but why play Russian Roulette with some rather expensive hardware.
