Looking for feedback & advice here.
HVAC system for high quality custom timberframe home (2900 sq. ft) to include 2 air handlers, one each for upstairs and downstairs. Ductwork to go in crawl space. The contractor wants to use all flexible duct. I like his system except for this. I’m not that impressed with the stuff and don’t want something of mediocre quality going into a house of this caliber.
What’s the deal with the flexible duct? How about insulated flexible metal duct (aluminum lined)? Would that be better?
What should I tell the contractor? Get another bid? Can anyone provide reassurance that this is a good way to go? I get the impression that flexible duct is a compromise.
Cost is always an issue but does labor intensive sheet metal offer any real advantage over the others?
