venting range to roof or exterior side?
My downstairs neighbor is remodeling her kitchen and proposing to vent her range to the exterior side wall between our 2 units (right above her window line and a bit below mine- between our bathroom windows which are not far from the bedroom windows), My question: what's the likelihood of my smelling her exhaust (grease etc) through my windows?
Depending on the breeze, I'd say the chances are good. Our vent is through the wall and my son knows what's for dinner as he walks up the driveway. I also know when my next door neighbors are cooking steak and their vent is probably 40 feet from our house with bushes in between.
"My question: what's the likelihood of my smelling her exhaust (grease etc) through my windows?"
Well, only if they're open. My son's vent is onto the deck, you can not only smell it, you can feel the heat it draws out of the kitchen as well. You would probably be less likely to smell it if it were vented through the roof, but, that could change depending on the wind direction and how it flows over the structure and exactly where the vent is located on the roof. My guess is you're going to know what's for dinner downstairs either way. Our vent in our house in NY vented to the garage, not a good idea.
The smell and the grease are two different things. Cooking smells are unavoidable, but not generally objectionable. Grease, however, can go out a vent as vapor and condense on things on the outside. The severity of this problem depends on the type of cooking they are doing and the type of venting system used. Vent-a-Hood, for example, claims to condense most grease in a trap before the air is exhausted. A filter-type system will trap some grease, but will be less efficient.
