    When we come across a furnace installed in a bedroom, bathroom, or adjoining closet, it is usually because the room was originally a garage or utility room that got remodeled into a bedroom suite. The homeowner left the furnace in place and remodeled around it, to avoid the expense of relocating the unit and its gas service piping, plus reconfiguring the ductwork.

    No isolation system is foolproof, so we always recommend installing a CO alarm in a bedroom or bathroom with direct-vent furnace or one in an adjacent sealed closet.


While we hope you find this series of articles about home inspection helpful, they should not be considered an alternative to an actual home inspection by a local inspector. Also, construction standards vary in different parts of the country and it is possible that important issues related to your area may not be covered here.
