Best source for ridgid duct supplies?

Don't like the flex duct all over the place that the contractor installed years ago. Where is the best place to get ridgid duct supplies (round or square metal ducting)?


Smart man woulda posted this in the correct forum, Mods, please move?

Have you tried any small HVAC shops around you? Dont know just what you need .But they could make up a lot of stuff you will need. if in the attic Id still use the silver flex pipe. Might try

sorry for lack of detail, ducts are in semi-finished basement area. several of the ducts appear to be so bent and twisted to make clearance that they must be restricted, plus my personal theory that the "ridges" on the inside of the insulated fexduct must cause some restriction or velocity loss of the airflow. and the insulated flexduct in an area that is part of the heated and cooled portion of the house, does it really need to be insulated?

We do not use flex or insulate Duct work in a open basement at all. We also put two small registers and a small cold air return down there. This helps the home in to heat the floor and cool the basement some so the ducts dont sweat. There is no loss . As it goes up to the floor.

Yes get sheet metal pipe and use 90o L 's there. It should give you a much better air flow also.
