I have a finished basement, ground floor, and upstairs. The ground floor and basement cool nicely with the AC. The upstairs doesn't cool very well. The returns are really just holes in the drywall- there are no ducts behind them. The ground floor has a 30"x6" return vent. The upstairs has that plus 2 15"x7" return vents. I checked last night and there does seem to be decent movement of air into the big upstairs return (one or both of the other two seemed significantly weaker). My primary question is if it makes sense to block air behind the wall above the upstairs ducts? I'm thinking of using expanding spray foam. My reasoning is it would help seal the inside and create better suction.

I'm open to other ideas too. Since I moved in 4 years ago, I've: had the attic insulatedavoid air duct cleaning scams had the ducts cleaned and sealedair duct cleaning in kalamazoo mi put supply register boosters on 2 upstairs bedroomsair duct cleaning in marin county ca increased the HVAC blower fan speed All the things you've done should have helped some, except the duct boosters. They can't add much flow to the system unless the return ducts were increased proportionally (or similarly boosted). You get increased flow by increased pressure or larger ducting. Keeping upstairs doors closed will help by slowing the 'fall' of cooler air downstairs. Try leaving fan "ON" for a 24 hr period to see if your house will equalize better.

You can force the system to concentrate on the upstairs by reducing both the supply and return vents in the main floor and basement. You may have to do some makeshift blocking (reduction ) of the returns with plastic sheeting and 'no residue' duct tape. If successful, I believe magnetic covers are available. AFA blocking above the upstairs ducts, by all means. Save yourself some expense (and trouble, that much foam is hard to scaffold in a vertical shaft) and make 2x4 blocking (essentially fire blocking) to go above the vents. If you have typical framing 16 inches on center, a 14 1/2 inch piece will span stud-to-stud. Use a pair of pocket screws on each end to secure the blocking in place. Use fire caulk/foam for any gaps.Browse other questions tagged hvac or ask your own question.Optimum performance for Ford and Lincoln vehicles Help eliminate dirt particles that can enter through the intake system and upset the proper mix of air and fuel to the engine Tight, leakproof polyurethane seals are superior to plastisol seals
