Anyone have a the GE Monogram® 36" Wall Mount Vent Hood ZV950SDSS? It's rated for 700 CFM's and I need a min of 600 CFM for my cooktop. I like the tapered look and chimney style. Is this unit noisy? Any problems with it? Thanks for any feedback.

A custom duct cover is probably less expensive than getting an island hood to solve your problem. (The "chimney" on the hood is really a cover for a duct that the air flows through.) Because an island hood has to be finished on all 4 sides and has to support its weight from the ceiling, it normally costs more than a wall hood which normally has 3 finished sides and is supported from the wall. About the smallest price difference I've seen between the wall and island models of the same hood was $500 and it can be over $1000. The custom duct cover for our hood cost about $500. That was to get a duct cover made with trapezoidal sides because there was a sistered joist in the way of where we wanted to hang our island hood. Since it was for an island hood, that was for something strong enough to support the hood. That is a lot more weird request then getting a "flange" on a wall duct cover. A wall duct cover usually has 3 sides with just flanges at the back for screws. So what you want might be more like a small step or notch in the sides of the duct cover so that the sides are 1/4 inch deeper above the backsplash. I'd expect that to add much less than $500 to the duct cover cost. To ensure that you get exactly what you want, you should draw up a sketch with dimensions showing it. Independent, who made our duct cover, required a sketch from us before they would quote. There might be some practical problems with an island hood against a wall. If it is installed tight to the wall (so that its rear edge touches the backsplash, there might be noise from vibration since it won't be screwed to the wall like a wall hood would. If it isn't tight to the wall, it might be difficult to clean behind and some grease and steam laden air might flow behind it. If your backsplash goes behind the hood, screws will need to go through it that attach the hood to the wall.

First, the ducting has to be steel so care is needed to assure that any flexible ducting is the correct material. You can make a duct path as tortuous as you want, so long as the blower being used is capable of the necessary flow rate at the pressure loss you have incurred. Generally, the baffles or mesh filters dominate the pressure loss so a short length of bends is not too critical. Consider an angled duct path in the wall with two 45-degree bends. What size duct is in play here?

Am looking for recommendations on wall mount vent hoods please? What did you buy? Do you like it? Regrets? Happy? Pics if you can.. I’m going to need a 36” wide stainless over a 30” pro type range.. stainless steel - interior vent size is negotiable- price depends on brand / ratings but would like to keep it under $1000 or less.. thanks!
