How to Install a Range Hood Vent Through Ceiling? (Step-by-Step)

Ductless vs. Ducted Range Hoods

Range hoods use fans to draw up grease and steam, along with food odors and excess heat, but not all hoods perform the task equally well. The difference between average and effective largely depends on the type of ventilation available: ductless or ducted.

  • Ductless models do not vent to the outside of your house. The fan on a ductless range hood draws in air and circulates it through a charcoal filter, which traps grease and some odors, but it’s usually not as effective as an exterior-vented model. The less expensive of the two styles, ductless range hoods can cost as little as $50, and go up from there to several hundred dollars.
  • Ducted range hoods are more effective than their ductless counterparts, and they, too, have a wide price range. Ducted range hoods draw in cooking air, then whisk it outside your home via a wall vent or upward through the ceiling joists and roof. More affordable options start under $100, but homeowners who want a high-efficiency or designer ducted hood could pay well over $1,000.

The option for ductless or ducted also applies to the popular and space-efficient microwave-hood combinations. Homeowners shopping for a new combination unit often (mistakenly) focus primarily on the features offered by the microwave. But it’s also important to weigh a unit’s ventilation capabilities to make sure you’re selecting one that’s sufficiently effective and efficient for your needs.



How much does it cost to have a range hood installed?

Typically it costs between $200 and $500 to install your range hood. Island range hoods tend to be more expensive than wall or under cabinet range hoods.For more information on range hood installation cost, check out this article.

Do I vent my range hood through the wall or roof?

You have two options to vent your range hood: through the wall or through the ceiling.

Wall and under cabinet range hoods vent through the wall or ceiling, while island range hoods must be vented through your ceiling.

When choosing how to vent your wall range hood, there are a few things to consider. What is the shortest distance from your kitchen to the outside, with the least amount of turns or elbows? Find this distance and your hood will run at its optimal efficiency.

Second, do you have anything obstructing your ductwork? You want to pick a path that is completely unobstructed to allow for a smooth and affordable installation.

Range Hood Venting Options

Here are a few different ways you can install your wall or under cabinet range hood.

The most common way to install your under cabinet hood is to duct horizontally through the wall. You can run the ductwork horizontally (option 1) or vertically for at least 18 inches and then insert an elbow (option 2).

Or, you may want to run your wall mounted range hood vent through the ceiling instead.

Finally, here is a diagram that shows how your island vent hood will look with the ductwork installed.

#3. Ceiling Support

Some island range hoods may need to be supported at the joists or studs. Make a wooden support and attach to the top of the studs or joists.

#5. Install The Vent Duct

Now it’s time to install the flexible vent duct, likely either 6-inch or 8-inch depending on your range hood.

You will need to connect this to the exterior vent hose either with aluminum tape or strapping.

Vent Hood Filter

Here’s how the three most common grease-trapping methods work

•Metal mesh

The hood’s blower pulls smoke and vapors through several layers of aluminum or stainless-steel mesh, catching the grease. These removable filters should be cleaned regularly—most can be popped into the dishwasher—to prevent clogs that can slow airflow.


More common on high-cfm, commercial-style units, these slat-style metal filters force the smoke to change direction several times, causing grease droplets to separate from the air and drip down into a tray that can be taken out for cleaning.

•Centrifugal traps

In place of a filter, centrifugal force within the blower liquefies grease, which is collected in a tray or a cup that’s removable for cleaning. With no filters to slow the airflow, these hoods require fewer cfm than those with baffles or mesh to do the same job, often with less noise.

  • Sump: Inverted area along the rim that collects fumes until the fan can exhaust them. Should be at least 1 inch deep.
  • Filter: Traps grease before it can reach the blower and ductwork. Metal mesh filters are the most common type.
  • Blower: Also called a fan, it moves air into the duct. Most blowers are in the hood, but they can be located “in-line,” up in the duct itself, or externally (inset), where the duct terminates.
  • Ductwork: The metal channel that leads the air out to the exhaust vent.
  • Damper: Prevents outside air from coming in when the fan is off.

Note: Vent hoods over 400 cfm require that makeup air be brought in from the outside when the unit is on. This air can come from a supply fan, a motorized damper, or another source.

Does a range hood need to be vented outside

Since a gas stove produces a lot of heat and harmful contaminants, venting the range hood over the gas stove outside the kitchen is helpful. The range hood, vented outside, keeps the air clean and fresh. In most cases, ductless hoods can be used as electric stoves are not very powerful. They take away all the smoke and cooking exhaust from your room, whereas ductless hoods recirculate your cookery exhaust into your room.

Installing a Hood vents through outside walls

This is very similar to installing your vent through your roof, but it’s a bit different.

It is assumed that there is vinyl siding on your home, and for any other siding types the installation is quite similar. You are going to need the right ducts as well as a vinyl vent. You can also use a dryer vent too, but it could be too small as a typical dryer vent is only 4 inches wide.

You can purchase a vinyl mounting box that comes in 12 inches by 18 inches. You will need to cut a round hole at the right size for your duct. Then attach the vent using the mounting box using flat head screws that are quite long and do this between 2 inches and 3 inches apart around the mounting box.

Next, apply clear roofing caulk or exterior caulk to create a seal between the vent and the mounting box. You will have to trim the vent flange to be able to fit the mounting box. Once your vent has been installed and then sealed, you will just need to attach your duct and then it is complete.

Key Tips

During installation, ensure that power outlets con
  • During installation, ensure that power outlets connected to the kitchen and located close to the venting hood are switched off to avoid any potential electric accidents.
  • When cutting the wires for installation, using wire nuts is a good option.
  • Also, never do the whole installation process with wet hands as these could lead to electric shocks.
  • Insulating the ductwork will prevent leakages. Make sure to do so.

Range Hood Maintenance

Once you’ve installed your range hood, keep your investment fully functioning for its expected lifespan by giving it regular attention and using degreasing cleaners. Because range hood fans draw up grease and steam, prevent a sticky buildup from forming by spraying the underside of the hood with kitchen cleaner and wiping it down as frequently as you would any other surface in your cooking space.

If you cook a lot, it’s also a good idea to wash the exhaust fan filter at least once a month—otherwise, its holes may become so clogged with grease that it will no longer work effectively. Simply slide or pop out the stainless steel filter, place it in the sink, and scrub it using hot water, baking soda, and a degreasing dish soap. Some filters (check the manufacturer’s instructions) can be put directly into the dishwasher for even easier cleaning.
