How to Install a Range Hood Vent in Your Kitchen

Home Improvement

If you’re like many homeowners, you prefer to install high-quality appliances in your kitchen that will last years without needing replacement or repair. One of the most important parts of any commercial or residential kitchen is the ventilation system, and this includes the range hood vent that pulls hot air out of your cooking area and into the rest of your home. This guide will walk you through how to install a range hood vent in your own kitchen so that you can keep using your home appliances to cook delicious meals for yourself and your family!

Selecting A Range Hood

Before you purchase and install your range hood, you’ll want to select one that will ventilate your kitchen efficiently. First, consider what type of air flow is best for your kitchen space. The right choice will usually be dependent on whether or not you have wall-mounted exhaust fan already installed. 

If you’re trying to replace an existing range hood, either with a different model or another venting method altogether, it might be easiest to start from scratch by removing any remaining pieces of the old unit. Otherwise, make sure you measure correctly so that your new unit fits properly within its designated space.

 And don’t forget about electrical wiring! Make sure to factor in access points for any cords and switches when measuring. To install a range hood through your ceiling: Determine which side of your roof would offer better ventilation – Typically, ranges are vented out through sloped attics (the bottoms of pitched roofs). So if there’s enough room near where you plan to locate your vent (and if there’s nothing that would obstruct airflow), placing it at least 8 inches from the peak of your roof’s slope should provide better ventilation than vented through flat attic spaces. 

Trace out both sides’ measurements before deciding; sometimes things are smaller than they appear.

Measuring Up And Cutting The Hole

When it comes time to install your range hood vent, you’ll want it centered over your cooktop. Measure across from each end of your vent and measure up from each end. Center those measurements on one wall and mark them as well as four or five inches on either side of your marks for cutting into drywall with a drywall saw. Next, use a level to make sure you have an even gap all around and then tape off where you’ll be cutting. Cut out using a jigsaw or hole saw, making sure to clean up any rough edges with sandpaper or files. After that, place ducting through so you can connect it to your new range hood when installation is complete. 

Attaching Gasket To Mounting Plate

After installing your mounting plate, place your gasket over it and begin pressing it into place. Use an adhesive such as liquid nails to keep it from shifting around when installing ducting or any electrical components later on.

 Screws can also be used but won’t provide quite as good of a seal. If you want your range hood vent to be really secure, use two screws through each corner of the gasket and one in each middle square on either side of them.

Marking & Cutting Electrical Box Cutout

First, you will want to mark and cut out an opening for your electrical box. Measurements vary depending on your installation plan and type of range hood you’re using, but for reference, I placed my electrical box with its center at about 2 1⁄2 from either side of where my range hood ducts would be and about 1 1⁄4 down from my ceiling.

 You can always use a stud finder to locate wooden support beams underneath, too. Next, I made my cutout by using a jigsaw. Start slowly at first so that you don’t make any mistakes – these cuts are fairly permanent! Then, clean up your edges with sandpaper or an orbital sander if needed.

Installing Brackets & Attaching Support Hangers

When you’re installing your range hood vent, it helps to have someone hold up some support hangers while you place your brackets. This is especially true if you’re doing it alone. These support hangers will make your life easier, though they aren’t totally necessary if you have extra hands on deck (so to speak). 

However, always use wall anchors when hanging large objects, such as appliances; these are great for small jobs but can cause issues with heavier items—such as an entire range hood! If you’re hanging heavy stuff above stove or counter tops, ask a professional carpenter what they’d recommend.

Fastening Exhaust Pipe To Mounting Plate

A basic range hood vent assembly includes a damper, ductwork and an exhaust fan. The damper is essentially like a hatch on your attic, but it’s located inside your kitchen instead of outside. When you pull down on it, it opens up and lets air come into your home.

 When you push it back up, air flows out of your home. The ductwork is the metal casing that surrounds and protects the inner workings of your range hood vent system. Ductwork is available in many different styles, sizes and shapes; round ducts are most common but square or rectangular ducting are also options.

Assembling & Installing Ductwork And Damper

When you install a range hood vent, you will also need to install ductwork and a damper. Ductwork is necessary for ventilation. If your venting system does not have it, you can purchase an appropriate duct kit at most hardware stores.

 The installation of these items is fairly straightforward; be sure to read any specific instructions that come with them when installing them for use with your range hood vent. Attach one end of each pipe to your existing ductwork, then place them inside a smaller, shorter piece of pipe—this helps keep all of your pipes organized and also helps increase airflow and pressure.

Fastening Sheet Metal To Ceiling

To install your range hood vent through your ceiling, you’ll need to fasten sheet metal onto your ceiling. One of two common ways is to use screws and nuts (most common) or rivets.
