When we change out (next spring Lord willing) we're thinking of moving the AH to a closet in my office rather than the living room. They share a common wall and of course a new return hole would have to be cut.
Have you ever moved AH locales inside the house and will this be a bear to accomplish for my highly professional, professional?
(Post Script) The reason for this is the return air is right in my wife's ear when she was watching TV and its POing her on a continual basis.
Once aGAIN, thanx for the info ahead
