I would have thought the HVAC company would be in a better position to suggest the better option, but personally I would inclined to go with 2 smaller returns if one of the new returns is placed in another area of the house and not so close to the existing return and the new return in MB.


He did say something about adding the third return air vent benefiting the pressure? I am an idiot when it comes to any repair beyond what I can do with basic tools. The downside would be that the if the third return air was added it would either be in another bedroom which would be fairly close to the current return air in the hall or in a common area of the house that quite frankly gets cooler than the rest of the house already.

Well you can certainly go either way, and if a second return has to be placed in a location you rather not have, then go with the larger MB return duct, it should solve your problem assuming no other issues you are not aware of. But again remember after the new return air ducting is installed you should be able to to adjust the dampers in the ducts to hopefully better distribute the air equally to all areas of the home so that you have uniform cooling throughout.

Also try to keep doors open to all interior rooms, if there is no need to close them, which helps draw air throughout the house to the air return registers.
