But I know there are many hear in the Villages who have used these products for over 20 years and never had a problem and it's because they had an older system. I'll bet if they opened the airhandler and looked at the evaporator coil there would be significant corrosion. On the newer systems the coil material is different so they only recommend hot tap water.

I find it interesting that the average Joe could get to/access their evaporator coil to use the wrong solution and hasten corrosion. How many average homeowners know where the evaporator coil is? There has been conversation here regarding what products to use to flush the condensate line, but I’d wager less than 1% of owners in TV flush their evaporator core with anything, much less the wrong thing.
