Is it worth ducting a range hood to the outside?
I am in the middle of a major kitchen remodel, and am considering whether or not it will be worth the effort to vent a range hood to the outside.
We are going to have a conventional (gas) 30" range, located on an interior wall that runs perpendicular to an exterior wall. In order to vent to the outside, I would need to run approx 5' of horizontal ductwork above the cabinets and then outside.
Above the range we will have a combination microwave/vent hood.
We have never had an exterior venting range hood before. Just recirculating type.
My question boils down to whether or not this would be worth the effort. Has anyone gone from a recirculating type to the vented type? Is the difference worth it?
Thanks!

I did switch a microwave vent from recirc to outside. Worked well. Check the manufacturer's specs concerning vent run, elbows, etc. Be careful doing the work....fire depts don't like them.

I would only consider a vent that exhausts outside. Without it the hood is mostly useless. You may also be able to run your exhaust duct vertical and go out through the roof if you don't have a second story. Also, the ducting must be rigid galvanized steel. Aluminum or flexible "dryer" hose is not permitted.

Agreed this is worth the effort, especially since you are remodeling. 5 feet is no problem.
By above the cabinets, do you mean in the joist cavities or in a soffit above the cabinets?
Are you sacrificing upper cabinet height to run the duct?

Yes, worthy!
I regret during my ongoing remodeling having put, again, mw/recirculating vent combo. This newer, upgraded type has zero efficiency. Whole house smells like whatever was cooked yesterday (all the way to 2nd floor, which is now the vent). Also, indoor humidity increases a lot during cooking.
I've tested the vent with a thin kleenex, and hair. They don't even move in the direction of the vent! Of course, one cannot test this at the store...

It's not the best but should help in your situation.

The old reasoning behind a hood was to reduce the odors from cooking. Newer thinking has included air quality and the gas products given off from the stove, along with the moisture. It is now recommended that the exhaust fan be run anytime the gas is being used. In today's more energy efficient air tight homes air quality has become a high priority. Vent to the outside for sure as others have stated.

If I do this, I'm thinking I'll just run the ductwork right on top of the cabinets.
The top of the cabinets is right at 8' above floor grade. There is one more foot before you get to the ceiling. That gives me some room. I could run the duct back against the wall, above the cabinets, and it would be all but invisible.

Sounds like a plan. The duct might not be visible and is well worth the effort to have it there.
Be aware that a MW hood vents nowhere near the quality of a regular hood. I have one because of convenience and it's better than recirculating.
No matter the quality, they all vent marginally at best. I would call it good enough.
Normally you would run 7" round above the cabinets, but I would have no problem with reducing that to 6" round.
