4 Things To Consider Before Installing a Vent Hood

4 Things To Consider Before Installing a Vent Hood
  • Opening Intro -

    Adding a vent hood to your kitchen is a great way to improve style and ventilation.

    Vent hoods whisk away cooking grease, fumes, and smoke, making your kitchen safer and keeping it cleaner.


Before you add just any vent hood to your kitchen, though, there are some things you need to. Keep reading to learn four of the most important things to consider before installing a vent hood.

Mounting Options

You have a number of mounting options, depending on the layout of your kitchen. If your cooktop is on an island, then you’ll need an independent vent hood designed to mount over an island. If your cooktop is against a wall with cabinets over it, you’ll need a vent hood designed to mount underneath cabinets.

For custom cabinets, you’ll need a custom vent hood. And if your cooktop is against a wall without cabinets over it, you’ll need a wall-mounted vent hood.

If you’re remodeling your kitchen and don’t know where the cooktop and vent hood will be, consider your ceiling height and where adding ducting would be easiest, if you want a ducted system.

Ducted vs. Ductless

Vent hoods are just another name for range hoods, and despite the name, not all vent hoods have vents. You can choose between a vented, or ducted, system for your hood or a non-vented (ductless) hood.

A ducted system will collect the dirty air from your kitchen and vent that dirty air elsewhere, ideally outside your home. There are certain places you can’t vent, such as into a garage.

So if you want a ducted system, make sure you have safe venting options. On the other hand, ductless systems suck in the dirty air, filter it, and then release it back into your home.

Although they’re not as effective as ducted systems, if you don’t have a safe ducting option or live in a location that doesn’t allow you to add ducting, such as a rental unit, this may be your best option.

Size and Power

Getting a vent hood that extends six inches past either side of your cooktop is a good rule of thumb. That means if your cooktop is 24 inches wide, you’ll want a range hood that’s 36 inches wide.

When you’re choosing how powerful of a hood you want, you’ll need to do some calculations. Hood power is measured in cubic feet per minute, or CFM.

You can determine the minimum CFM you need by dividing your gas cooktop’s BTUs by 100. For an electric cooktop, you’ll multiply the width of your cooktop by 10 to get the minimum CFM.

Noise Level

The last thing you need to consider before adding a vent hood to your kitchen is how noisy it will be. The bigger and more powerful of a hood you get, the more noise it will make. However, it will also work better and faster.

Once you calculate the minimum CFM your cooktop needs, you’ll have to see how many decibels of noise a hood that powerful makes and decide if the rewards are worth the increased kitchen noise level

Once you’ve considered these four vent hood factors, you can make an informed decision on whether you want a vent hood in your kitchen and what type to get.
