Hello All;
I am about to finish my basement and have 2 strange sheet metal hvac runs.. they come out of the main stack on the furnace - same size openings then for some reason they cross over one another.. ie.. the left side comes out and crosses under the right side.. anyway I want to rework the ducts so they are more effecient.. ie.. the left stays left and the right stays right.. anyway.. is it worthwhile to replace the sheet metal with the flexible stuff or should I tape (sometheing that was not done when the house was built 2 years ago) the ducts and rework the sheet metal. There will be a drywall ceiling - that I am contimplating insulating.. thats another question can I stuff insulation around the duct work or should I just leave it?
thanks!
jim
