Anyone see the recent Ask This Old House show which featured a new
product for creating zones for forced air systems? It creates room by

Anyone see who makes this product and have any experience with it?

I got this message "We're sorry, MyTemp is currently only available in

I saw that segment- while amusing, it looked awfully Rube Goldberg to
me. And at that price point (especially for somebody that can afford a
13-room house), seems like the traditional solution of splitting the
plenum and installing a second furnace and separate Tstat may not be
much more expensive. I think they did mention that the original HVAC
company stupidly commingled the duct trunks for upstairs and downstairs.
When I was a wee lad and my father built his folly for us to live in, it
had similar problems, and a second furnace was what we ended up with,
but in that case splitting the plenums and returns was trivial due to
the house layout. (This was the first partially multi-level no-attic
flat-roof contemporary he had built, and not having an HVAC engineer on
staff, it was a learning experience for all)
