I don't know if my acronym is correct but I mean a underfloor air conditioning system. I have a pier and beam home in which we are remodeling and the contractor is suggesting a underfloor system by which each room will have its own blower. He said they have used it in Japan forever and it is just now making its way to the US. Has anyone ever heard of this system and is it reliable and cost effective? We live in Texas where it is very hot 90% of the year and alot of humidity. Any thoughts or recommended reading? The contractor has not mentioned the upfront cost only that it will save alot of future money on lower energy bills.
