Product review (3 stars): Broan 36" QS2 range hood
Has never been very quiet. Others have mentioned the poor exhausting from the right hand side, and we've had the same isues. After 4 years now it's even noisier than ever. The cheap plastic blower wheel is badly warped from stove heat, and yes it is properly installed with over 24" of clearance from the stove surface. I wouldn't buy Broan again. I believe a little shopping around would find a quieter, more efficient hood in the same price range.
