I guess I should have clarified things a bit more. I was talking about new homes in general.....not retrofits. I'm thinking that if the heating contractor is there putting in ductwork anyways, doesn't it make sense for him to install the ductwork for the exhaust fans?
Same with cabinetry - the cabinet installers are there, they have the proper tools, why not get them to cut out for the electrical boxes?
Once again, I'm talking about new homes here - my intent is not to pass work off to other trades un-necessarily. Of course I will install some ducting for a bathroom or a range hood, and cut out for receptacles, ceiling boxes, recessed lights etc. in a retrofit. But new homes are different - all the trades are there.
My expertise, such as it is, is for electrical. I don't know, nor do I want or need to know air flow calculations, static pressure, etc.
