Have a Finished Basement except for the Furnace Room & Utility Room.. We have a Bedroom & Rec Room in in the Basement, the objective is correcting the Heating situation into those rooms during the Winter Months.. The heating Duct Work Vents are in the Ceiling.. And there is NO Cold Air Return tied into this, the existing Cold Air Returns only serve the Main Floor. My question, Would this be a major undertaking to install a Cold Air Return in the basement or is there any other Solution ?? Thoughts & Opinions Appreciated, Cheers Thanks
