Hi, I'm a homeowner with an HVAC related question. I have a 1250 sqft ranch style home with forced air AC. There is a single return air register located in the wall at floor level in the main hallway. The floor level register is linked to the attic flexible return duct by a rigid duct running vertically through a closet that used to contain the water heater (relocated to the garage). I'm remodeling my master bathroom and would like to extend my shower into the hall closet, but to do so, I would have to remove the rigid ductwork and move the return register. The easiest way to do so is to put a return register into hallway ceiling directly above it's current location in the middle of the hallway and connecting it to the existing return duct. My contractor thinks this is a good solution and would like to proceed, but I wanted to get other opinions about whether moving the register would adversely affect circulation and/or HVAC performance. Thoughts? Thanks!
