Microwave and Hood Fan CombinationsYou can also integrate a combination appliance for kitchen ventilation. There are pros and cons to this option, and it's a matter of personal preference. For many homeowners, a microwave is a no-brainer. However, the accurate positioning of a microwave can be challenging — particularly in a small kitchen — since it often takes up valuable counter or shelf space. Using a combination microwave hood fan above the range puts it out of the way, into a spot that would've been used by a vent anyway. It often strengthens the concept of the stove area as the main feature in the kitchen too, without the visual clutter of other appliances. It's definitely worth considering in small to midsize kitchens. However, this location also makes the microwave very difficult to reach, since you have to lean over a potentially hot surface. I would never install a unit like this over a gas range — the open flame could become very dangerous.
