I got this tip from an AC service professional.

Pretty similar from my AC company. For some reason (?) my Trane had no safety cut off (???) so had a puddle of water on the furnace pedestal before I realized what was happening. I used the tablets you just drop into the line for a long time after that, but AC person told me that a cup of vinegar would do the same thing much cheaper as long as I set a day *first day of the month, and do it every month without fail. For over a year had worked just as well as the costlier tablets ! Bought the super size Costco 1.50 gallon size to put out in garage to remind me !
