I am having a duct put in for a range hood. I plan on redoing the kitchen in the next year or two, but am installing the ductwork for the hood now. (i am putting on an addition and it makes more sense to do it at that time. It will have to be vented up to the roof since the addition will be abutting the kitchen.) I was wondering if there is a standard height for the ductwork? my stove it 36inches height. 8ft ceiling (actually 95 1/4in to be precise:) I plan on having the bottom of the hood about 30inches from the cook top, give or take a few inches. This will of course depend on the height of the hood itself. The main issue is, I don't want to have it at a height which will cause problems if/when I ever wish to install new kithing cabinets! ie hard time finding cabinets that would accommodate a hood at the height the duct is on the wall. When the time comes for replacing the cabinets, we are planning on the ones that go all the way to the ceiling. thanks. PS, If there is a more appropriate part of the forum for this question, just let me know.

Hey guys, just about winter here and we are looking into replacing our old ductwork, for several reasons. #1 it is quite old (the house itself is around 70-80 years old or so), #2 it has been painted inside by old owners and this is peeling amongst other dirt and #3 there is some areas with asbestos wrap. We are having some trained asbestos professionals to come and estimate removal of the asbestos sections - there is not much. Once the asbestos is removed, we want to save money on the removal of the old ductwork and installation of the new. So I figure, with the asbestos safely gone it shouldn't be too hard for us to tear out the old ductwork, right? Now for installation I am not as sure... I assume that I could do it all myself but it would be challenging. So I was thinking at the very least I could install the basic runs myself and mount them into the basement ceiling and have a contractor come and do-up the connections where needed, no? Would flex duct be easier for a DIY job or metal duct still recommended? Part flex? Educate me guys! If we had more money available, we'd let a pro do it all but finances necessitate that we help out to reduce the financial burden where possible. Also, here is a picture of one of our registers. [IMG]http://img208.imageshack.us/img208/4096/p8040722.jpg[/IMG] This one has asbestos wrapped on the outside of the register boot in the wall, behind that black area. It was sprayed with spray adhesive to encapsulate the fibers after it was unintentionally disturbed by a negligent contractor during a bathroom reno. I will ask the pros this when they come to estimate, but I thought I'd get your opinions too. It would probably be better just to make sure the boot is well sealed off instead of having the guys rip it out and potentially cause more disturbance, right? And then perhaps just installing a new register in or around that one since these old registers had very big openings. One final question. If all goes well and we get the new ductwork installed we also want to install a HEPA bypass. Any brand recommendations? And if we do install a HEPA bypass, since it is only a bypass, can we also run just any other random media filter in the filter area before the furnace? Many thanks guys, Cody
