I live in an older Victorian in the Boston area. Either a Unico-type system
or a Mr. Slim-type system seem to be my best options. I'm thinking of having
the system installed in the third floor (two bedrooms, playroom, and
bathroom, in total approximately 1100 square feet) because it'd be far too
expensive to do the entire house.
Any opinions on the relative merits or either system? Or approximate costs?
