Range Hoods - Everything You Need to Know

The range hood is the chief ventilation unit of a kitchen and consists of three main components:

  1. The Hood: Serves as canopy collecting all the smoke and fumes that emanate from the cooking surface.
  2. The Blower System: Sucks in the emissions of all kinds.
  3. Ducting: It exhausts the emissions out of your kitchen through a duct network.

It is important to understand that ducting is not always a part of the system, for more on this please refer to our page that discusses ductless range hoods. But irrespective of the type of installation you carry out, the range hood has two main functions: minimize cooking smells, condensation, and heat and the other important function is the prevention of grease build up all around your kitchen.

Range Hoods: Some FAQs

Can you vent a range hood down?

You definitely can, but you should not unless you’re buying a downdraft hood. Regular range hoods are meant to vent up or through the wall. Changing the direction and pulling air down would decrease the effective CFM and you would have to use a higher powered hood to get the same job done.

Should a range hood be vented?

Not all range hoods are vented. You always have the option to get a ductless range hood. But a ductless hood only gets rid of grease and odor. Any traces of toxic gases from a gas stove do not get exhausted this way. Also, it’s always wise to find out if you are required to vent out by law or not in your municipality.

Are range hoods hard wired?

Some are, some aren’t. But, if the model you buy does come with a plug, you could always switch things around and set it up so that it’s hard wired or vice-versa

What are the different kinds of range hoods?

There are mainly three popular kinds, but four kinds in total, they are:

  1. Under cabinet range hoods
  2. Wall mount range hoods
  3. Island range hoods
  4. Downdraft range hoods

Can flexible duct be used for range hood?

Of course you can, unless the manual specifically says you shouldn’t. However, you should know that any flexible duct that is not completely pulled out adds to the friction, thereby dropping the effective CFM of your range hood a bit, while at the same time increasing the noise produced. So when possible, stay away from flexible ducting. For every 25 feet of ducting there is a 7% reduction in effective CFM when you use flexible ducting, where as it is 3% if you use non-flex ducting.

Do you need a range hood for a gas stove?

If required by law, you would definitely need one. If it’s not required by law, you would only need one if you cannot have open windows or some other form of exhaust. The biggest problem of having a gas stove in an enclosed space is the build up of carbon monoxide and other gases; which in high quantities are toxic.
