My range is 36” gas stove that I inherited with the house. It’s only five years and it serves me well( as a light cook) when I’m ready for upgrade, I’ll probably get the same size. So I feel like 42-44” should be sufficient.

I don’t have a plan on make up air yet. I mean I can add this while getting new hood but I’d have to rely on local HVAC company to figure that out( and not get ripped off :-)

I see a gas stove. 36 in. 42 wide is fine ,900 is pretty good. With your sensitive nose and using gas , a stronger cfm would be great. Yale hoods have good cfm. Also, how deep. 25 deep is preferred.  Gas is on its way out in California.  Maybe consider induction?

I know… starting January 1st, I believe no gas stove can be installed in new build both residential and commercial. I did hear that there are some petition on the way to reverse this but who know…

If 900 CFM is not good enough, what CFM would you recommend? No matter how efficient the hood I’ll be getting, I’ll limit steak/grilling strictly to outdoor cooking. I can only count with a single hand cooking steak since lived in current house and although I’m planning on have dinner get together more often than the past, dinner party will still be few times a year thing. Although even smaller than 900CFM might be sufficient with the way I cook now,I’d rather spend money now on changing duct to 8”( or 10”?) and do efficient hood instead in few years when the labors inevitably will go higher

I’ll check out Yale hood now, didn’t know there’s option for 25” depth. Thanks!

Got it. I guess the first thing will be contacting HVAC before choosing the hood. Thank you all.
