I hang this type of duct nearly every week. Flex duct should never be longer than four feet in a single run. I would recommend having someone come out and have them reroute the duct work up in the trusses. Rigid duct work with an insulated jacket is way more efficient. Paint on flex duct will look good for awhile but in my experience the paint will begin to flake and peel after time and it's not a good look. Also the flex duct work was never meant to take paint. If you do use paint in the basement be very careful with the fumes. A gas furnace and hot water heater have pilot lights and that could be a bad mix.

What he said. This looks like the equivalent of using garden hose to run your plumbing. It may seem like lots of money to get it redone correctly, but you are certainly wasting a LOT of money sending your air through those messed up flex ducts. Doing it right will make a lot of it go away so you have more space to work with. It will certainly save you a lot on heating and AC bills over the years.
