My heating ir conditioning system is in a finished basement. Currently there six inch galvinized pipe runs to all the floor register coming off a galvinized trunk. The longest run to a register is about 12 feet. Is there any advantages or disadvantages for replacing these runs with insulated flexible duct? Having some issues with the current galvinized pipes doing a little popping and cracking during each heat cycle.
