American Range is a decent product but if you have any issues, the company might give you a big fat "%$#@ you, sucker!" like they did me. Customer service is important, and they failed miserably in that department.

I am not a fan. Spend more and get something else. :)

Check into make up air to go along with the ventilation for your range.

30"? BS has a number of options.

Consumer Reports (https://www.consumerreports.org/join) tested "pro-style" and gas ranges and found that the pro-styles didn't perform any better than the gas ranges and were much more expensive. The American Range ARR304 was the lowest-rated 30" "pro-style" range tested.

The part you don't want to hear is if going w/a commercial range you'll also need commercial strength ventilation. If your looking at a BS or similar you'll be way ahead budgeting at least $2k for a good hood and ducting, at least.......

Ventilation is often an afterthought and not considered a major appliance or work. It is, it's equally important as the range. If you can't ventilate the effluent you'd be better off not even bothering w/a commercial style range or hi-heat cooking. Those ranges create a LOT of mess, if your not familiar with hi heat cooking you'll get an education fast. If your a neat freak they'll keep you busy. Another thing, it'll never look as good as it does the day you install it once you start using it. None of those statements are meant to dissuade, just letting you know. It's the nature of the beast.
