You need to buy a Range Hood but do not know how to find the best one? Keeping these 4 things in mind when looking for one will help you adding value to your kitchen.

1. Know Your Kitchen

Kitchen Space Design and Best Practices

Your kitchen layout will determine how much space you have to work with when selecting the perfect range hood.  You might be looking for Wall Mount Range HoodsIsland Range HoodsRange Hood Inserts or Under Cabinet Range Hoods. It is important to know the height of your ceiling in order to determine if you will need a Chimney Extension or not. Keep in mind it is the industry standard to mount your Range Hood between 24 to 30 inches above the cooktop.

2. Too Much Power?

How big is your space and your cooktop? This will dictate how much power your Range Hood needs to work efficiently and effectively.

The standard rule is this:

100 CFM of airflow for every 10,000 BTU’s of heat energy

The formula for how to size your Range Hood over a gas is you need 100 CFM of airflow for every 10,000 BTU’s of heat energy. Now, this is the basic formula and your own cooking style may need more or less depending on how you cook and the configuration of your cooking area.

For example, if you are cooking greasy hamburger meat on a griddle in an island gas cooktop then you may need a higher CFM depending on how high the range hood is from the cooking surface. The coverage area, the CFM, and the range hood height and design play a big role in Range Hood performance.

Here is a typical example of how to size your Range Hood over a gas cooktop. Say the cooktop is a 48” Model with 6 burners and a griddle.

From the owner’s manual the small burners are 8,000 BTU’s and the large burners are 12,000 BTU’s and you have 3 of each for a total burner output of 60,000 BTU’s.

The griddle uses 20,000 BTU’s. Total BTU’s for the cooktop is 80,000. This is a very realistic example and using our rule above of 100 CFM for every 10,000 BTU’s you would need a minimum size of range hood in the 800 CFM size.

3. Exhaust Type – Vented & Non-Vented

There are two ways that you can set up the ventilation system on your range hood, a vented system and a non-vented system. The vented system uses ducting to channel the air away from the kitchen and out of the home. When building a vented system, you may want to consider mounting the range hood on an exterior wall in order to make the ducting shorter and more efficient.  The non-vented system, or duct-free system has the air filtered, cleaned and returned to the kitchen rather than directing it outside. You can use a recirculating kit or charcoal filters for this, depending on the model range hood you have.

4. What Is In Your Budget?

Range hoods come in all shapes, sizes and costs.

Much like any other appliance you purchase for your home, range hoods come in all shapes, sizes, and costs. The material used, size and power will all contribute to the final cost of your range hood. Do your research and compare prices before you press the buy button. Do not forget to factor in the cost of installation if you plan on having a professional do the job.
