Glad I found this forum, with all the jury-rigging and corner cutting the previous owner did I'll need a lot of information and help. So, Project #1: Dryer vent and exhaust fan. I need to vent the main floor dryer through the roof (instead of the 20 ft extension made entirely of flexible hose that has at least three turns before venting out of the basement). The dryer rooms shares a wall with the bathroom which has a exaust fan. My question: Can those systems be connected. i.e. connect the dryer lint vent pipes to the exhaust fan pipes and only have one exhaust out of the roof, OR do they have to be seperate. I can forsee the dryer lint just falling into the bathroom if I connect the two, but I would like to decrease the amout of vents in the roof and thought about this. Second, slightly related question: does one really need an exhaust fan in a laundry room on the mainfloor? Genius previous owner has one vented to just blow into the attic which seems to be pointless and I'd rather just remove the whole gosh darned thing. - Thanks in Advance!

We have central air and recently installed a home theater system in our basement which is not insultated, 40% under ground level and .......freezing. All the duct work down there has major amounts of insulation. The only part where there is raw metal is on the hot forced air furnace itself. What would be the easiest way to add a return down there? I want something that I can simply open and close based on the temp and knowing its movie night. I don't want to add returns all over the place, just in the one corner where we have the system.
