I am going to have the HVAC company add a return to our master bedroom. Obviously they are going to offer suggestions on how to accomplish this, but I wanted to get some ideas on how it’s usually done in existing construction.
This room sits over the garage, so there is access from underneath. Is it possible to cut the subfloor under the wall that I want the return in and slide the ductwork up into it? I would prefer the return be at the top of the wall. There is also a closet on that same wall, so I suppose a hole could be cut in the floor of the closet and duct/flex ran up the wall in the closet. I’d prefer not to do it this way, but if that’s the only option, then I will do it.
Thanks for your suggestions.
