Required Return Intake Size
I'm putting new cabinets in my kitchen and one of the walls I'm was trying to remove or move has the furnace return filter and intake box in it. How can I determine how much of the box I can remove or how do I determine the size of the intake box needed by my system?

Just curious. Why should there not be return in the kitchen?
I was considering putting a return in our kitchen ceiling because that part of the house gets very hot in the summer. The kitchen, breakfast nook and living room are basically all one room and there is no return in any of them. The ceiling is vaulted and is about 12 feet high. Is this a bad idea? Any other suggestions?

Your rooms are hot because of equipment or duct that is not sized correctly. We don't put returns in kitchen because we don't won't grease and smoke in the duct going to the rest of the home.

The equipment is properly sized (per my heat gain study last summer), but all of my returns are on one side of the house and are within 10 feet of each other. I was considering blocking one off and adding an additional return (same size as the one blocked off) near the kitchen (side of the house with no returns).
I was also told (by HVAC guy) that we have too many registers for our 2.5 ton unit.

Oh, then yes I had that done last summer. That's when I found out that my supply trunk was too large and has too many registers for my system. The HVAC guy suggested reducing some of the branches (from 6" to 5") and adding a return on the other side of the house. The only other option was to tear out the entire supply line and start over.
