Can I run range hood vent horizontally through cabinets?
First, you are most certainly better off with a venting hood than a non-venting hood. Filters can reduce cooking smells and oils in the air, but do very little for the moisture issue. In terms of your health and the health of the home, you need to get the moisture out. Technically, you could run your vent through the cabinets as you are suggesting. The first issue you will run into is the length of the duct. Shorter ducts allow the hood to perform much better. Elbows and transition fittings further reduce performance, so short and straight is best. The real problem I could see would be with the cabinets. Some cabinets are designed to use the side panels as part of the structure. If you start cutting holes in the side large enough to fit your vent, you may ruin the structure of the cabinets. Hard to make that call without seeing what you have. I would consider a couple of alternatives. 1) Place the vent in the interior wall vertically and through the roof. 3 1/4″ x 10″ rectangular vents
