Is your intake vent the first thing you notice when you walk into your foyer? Since you can't cover it with furniture (to allow proper air flow) for solution #10: we placed a console with a lower shelf, this allows accessories which help detract the eye. Large abstract art adds the cheerful touch this homeowner requested, it's allows the more contemporary feeling they preferred, next to the traditional mahogany dining room furniture in the adjacent room. This foyer is 9'3" x 17' x two stories tall, so this 64" painting was as a great size!
