Proper Ventilation | Selecting a Range Hood For A Kitchen Remodel

A properly sized, elegantly designed, range hood will make cooking more enjoyable. Learn why.

It's not glamorous like your new Viking Stove, or beautiful like your imported marble counter tops, but your ventilation is one of the most important elements of your kitchen remodel. Whether you have a Viking range or a cooktop, you'll need to consider your ventilation system options.

In an open concept home even if you have the perfect kitchen, without proper ventilation you'll have issues. When you cook, the smoke, odors, and particles released can hang in the air without proper filtration. A range hood is designed to remove smells, smoke, and particles from the room.

Let's look at the benefits and most common type of systems available as well as important factors to consider when shopping.

Five Additional Range Hood Benefits

While its primary purpose is to remove smoke, smells, and particulates from the air, a range hood provides other benefits to homeowners including:

• Providing extra light for your cooking surface which makes food preparation safer.

• Helps keep your kitchen cleaner. By removing smoke and grease it makes kitchen cleanup faster.

• Reducing carbon monoxide which can build to dangerous levels if your cooking area is not properly ventilated.

• Helps cool off hot kitchens. Along with smoke and odors, proper ventilation can help to remove heat.

• Even if you never cook, your range hood can add value when you sell!

Choosing the Perfect Range Hood: Types of Ventilation Systems

Today, you have a number of choices when it comes to ventilation systems. In fact it can be a bit overwhelming. Fortunately, your kitchen design will help to narrow your choices. If you're replacing a hood that is no longer working, it's best to stick with a similar hood that fits the space. If you're remodeling, your range hood can become an interesting focal point in your kitchen.

Here's a quick rundown of your options.

Under Cabinet Hoods

They mount under a wall cabinet and the ductwork runs into the wall or up through the cabinet and vents outside. Some newer models “hide” under the cabinet and then slide out over the cook surface when needed.

Wall Chimney Hoods

These are usually placed where there are no cabinets. They can feature decorative covers to hide the ductwork and usually vent through the ceiling or wall to the exterior of your home. In order to work properly, they should be slightly larger than the cooktop.

Downdraft Hoods

These pull odor and smoke downward into ducts running through the floor. Technology has improved in the past 20 years and today downdraft hoods are an excellent option for island cooktops. Some even drop down into the island when not in use.

Island Hoods

Mounted to and vented through the ceiling over your island cooktop. Because they have no cabinets to help funnel smoke, like wall chimney hoods, island hoods should be slightly larger than the cooktop surface.

Ductless Hoods

This option is available in several different types including under-cabinet, wall and island range hoods. They draw smoke and odor away from the cooktop and through a filter. It releases the cleaned air back into the kitchen. Some also include a carbon filter stage for odor removal. Ductless hoods are not the best choice. If they are not maintained they can disperse any smoke and odor not captured back into the room.

Specifications and Features

There are some technical specifications that are important to understand when choosing the perfect range hood. First, make sure it's the proper size and at least as wide as your cooktop surface. If you're ventilating an island cooktop, make sure it's a bit wider than the cooktop. Here are some specifications to consider:

Airflow

Measured in cubic feet per minute (CFM).The higher the CFM the more air the fan can move. Proper CFM depends on the type and size of your cooktop and also the way and how often you cook. For example, a 36” professional Wolf gas range will need a higher CFM than a 30” electric cooktop. CFM can range from 300-450 for an electric range to 1200 for a gas cooktop. The height above the cooking surface is also an important factor.

Fan Speeds

Some range hoods offer as many as six but you really only need two. Use the high setting when preparing food and the low setting after you're done cooking to continue to clean the air. More than three speeds really aren't necessary.

Automatic Thermostat Control, Exhaust Timer etc.

Higher-end models may contain these and other options like different lighting levels. Automatic thermostats turn the fan on automatically when a threshold temperature is reached. Exhaust timers shut the fan off automatically after a specified time period.

While most range hoods are utilitarian, there are some that offer an interesting aesthetic design. From contemporary glass hoods, to wall mounted range hood with copper covers, no matter what your design style there are attractive models available. The most important aspect of purchasing a range hood is functionality. Make sure you purchase the proper size, follow the manufacturers specifications when hanging it, and purchase a hood with the proper CFM rating.

When researching compare CFM, electronic controls and options, auto extend and retract functions (for hidden under-cabinet and downdraft hoods), filter maintenance indicators and access, and lighting.

Your range hood might not be the most glamorous appliance you'll purchase when undergoing a kitchen renovation, but it's hands-down the most important when it comes to day-to-day use and function.
