We live on a hillside. Our kitchen and living room are located on street level and our bedrooms are downstairs. The kitchen was a narrow galley kitchen with a small pantry and a 2nd upstairs bathroom. We had the kitchen, pantry and bathroom totally reconfigurated by making a smaller bathroom and moving it to another area. The pantry was eliminated allowing us to open up the kitchen and making it larger. Originally there was a narrow open doorway leading from the kitchen into a dining area and into the living room. We had that wall with the doorway removed which opened up the dining area and kitchen into the living room. The living room had a heating and air conditioning vent on the north wall and the other vent located on the east wall that was removed to open up the kitchen. My concern was if we eliminate the wall with the vent, that only leaves the one vent on the north wall. The company we hired to do the work said no problem we will move the vent to another wall. When it came time to relocate the vent they said they cannot handle those types of jobs. It was the only thing not written in the contract. They had also replaced the plumbing with copper pipes. The vent that was removed ran downstairs to the den. We found out the vent had asbestos lining and had to have another company remove it. The wall in the den is still open from the copper piping and the abestos vent column removal. It is now 2 years later and we have another contractor remodeling the den with the open piping. The base of the vent column had never been capped. Should we cap it and close the wall leaving the living room with only one vent or try having the vent moved to another wall. To the right of the vent is a lot of pipes so the vent cannot be moved over on the same wall and kitchen travertine flooring now stands where the vent originally ran upstairs to the wall that was removed. I am not sure if I am making any sense but if anyone can give me a suggestion - it would be much appreciated. Thanks

Do a manual D to find the necessary amount of duct in square inches and location. It is the only way to be sure.
