Retrofit Range Vent Duct – who to call
RickGreg
| Posted in Energy, Heating & Insulation on
I’ve been living with an unvented range hood for 10 years… just blows the fumes through a “filter” and back into the kitchen. The range is not on an exterior wall, so venting the hood will be tricky. It will require running duct through 10 ft. of cabinets to get to an exterior exit.
Any suggestions on what kind of contractor I should call for this?
Thanks.

You need a carpenter. A very patient carpenter.
It would probably take me a pretty good day to do that job.

Remodeling specialists are generally good problem solvers, especially for PITA things like this. (Carps who do mostly new construction just purely hate having all those #$%?*)$#@!!! cabs and trim work in the way when trying to knock a hole in the wall....)

A-holes. Hey every group has to have one. And I have been elected to be the one. I should make that my tagline.
Im a carp but I have my HVAC guy install the actual vent.
Family.....They're always there when they need you.
I had one of them, took a 4 inch hole saw. cut top of vent, through cabinet and ran 4 inch pvc out of roof, took all of 45 minute. and plug the filter vent
Don't believe that is kosher. For those who have fought for it Freedom has a flavor the protected will never know.
honest question, why?
I guess that would be ok for a bathroom vent but would be surprised if 4" is enough diameter and would expect codes to call for a metal pipe in case of a fire.
Have no idea what actual code is for your area. Hopefully someone with more knowledge will chime in.

IIRC, either a 3-1/4" by 10" rectangular, or 6" round, are recommended.
What was the size of the opening in your range hood?
And those duct sizes are only good for up 400cfm I believe... Any large hoods (especially any of the pro-sumer ones they're now selling that look like restaurant hoods) might require 10"+ round duct. 4" is definitely not enough for a range hood, and I'm pretty sure that the duct is required to be metal for grease fire reasons.Z
What isn't kosher ... running it up through the roof?? I think the vent close off was the vent returning to the room that he was referring to.
111876.12 and the one after it. I was not talking about disabling the filtered outlet. Most of the hoods I have seen are capable of going out or recirculate. Should be no problem closing the original off. Roof certainly is fine and usually will make for shorter run ( at least less turns). For those who have fought for it Freedom has a flavor the protected will never know.
Reread msg #7 .... I see ... PVC isn't kosher ... sorry ... missed their reference to the plastic pipe (and you didn't say specifically what wasn't kosher). Yeah, not kosher to use the PVC.
the county inspector ask me about that and what ok with it. I guess wally world really do screen their employees
I was also hitting at the diameter. As I qualified the statements I had nothing to quote but was more questioning the practice from gut feeling.

I usually try to roof vent. Last I did I built a box-out of drywall from top of over range cabinet to ceiling. Most call for min of 6" round or 3.5x10 vent.
A remodeler is your best bet. A lot of carpenters are not quite ready to hack cabinets and do finish effort.

Look for a remodeler or a kitchen salws and contractor that does complete installations of kitchens on a regular basis.
What you want done isn't a great head scratcher, but it will take someone with know how and patience.
No soffit above the cabinets? That's where I ran mine. I think you'll often find the soffit used for that. If you don't have a soffit ... maybe time to get one to hide a 6 inch exhaust duct. What's over the kitchen/range ... 2nd floor? attic? ... Up through the roof would be 'easy' (at least for us arm chair consultants :) ).
Call a renovation contractor who is a jack of all. A heating contractor might be able to do the job too if they are equipped as a retro fit contractor.
