No heat/air flow in the Bedroom Now Fixed

[concours]

I finally got tired with having very little heat in the bedroom, previously I had checked the ductwork for damage restriction etc. I replaced the 4 inch dryer hose with rigid and messed around trying to balance the other registers with dampers etc. I finally gave up and replaced the 4 inch duct that joins the lower ductwork to the upper with 7 inch the heat now works there is good air flow and heat. I takes a bit of work as you need to do some cutting of the ductwork and install new outlets but it's the best $45.00 we have spent on the trailer
