I routinely observe RH levels up to 75% in Florida homes in the summer with the AC on. In the winter I commonly see RH down to 35%. Still, you are right that an air conditioned Florida home commonly has significantly less extreme RH levels than say the average home in Duluth. However, if you have a nice piano that you care about in a Florida home and you prefer to have it in tune rather than out of tune, IMHO, you NEED good climate control. I have a DC on my piano at home and I find it energized often. On the other hand, I do not even talk to owners of 1952 Gulbranson spinets about climate control - unless they bring it up first - and then I only recommend it if they find they are having tuning stability problems - which of course they never do - think about it - does an in-tune Gulby sound a whole lot different that an out-of-tune Gulby? You get my drift.
