How to Install a Range Hood

While the scent of a delicious meal can be mouthwatering and enjoyable as you cook, lingering smoke and odors in the rest of your home can be less than desirable. A range hood can help keep smoke, grease, and odors out of your home, and installing a new one can be done with the right tools and some help. This guide will walk you through some tips and tricks on how to install a range hood, so you continuously create in a fresh space.

When choosing your new range hood, you’ll notice that there are two types—vented and ventless. Vented range hoods circulate odors directly to the outside, while ventless hoods recirculate clean air back into your kitchen with the help of a filter. The ideal range hood for your kitchen depends on a number of factors. Get help choosing the right one for you with this guide to 5 types of range hoods.

VENT HOOD INSTALLATION INSTRUCTIONS

Before installing your range hood, please note that this guide is an overview of the installation. You should always consult your owner’s manual for specific information and requirements needed to complete the process. Additionally, this should be a two-person job, and if you haven’t worked with electrical wiring or are unfamiliar with this kind of installation, hiring an electrician is strongly recommended.

Step 1: Shut off Power and Disconnect Wiring

Turn off the switch at the breaker box that powers the range hood. Next, unplug the range hood and disconnect all electrical wiring.

 

Step 2: Remove Old Range Hood

With the help of a second person, unscrew the support screws while the second person supports the weight of the range hood.  

 

Step 3: Locate and Mark Vent Location

Your vent location will be determined by the measurements of your range hood. If the hood came with a paper template, you can tape it to the wall as a reference point to see where the new vent location will be. 

 

Step 4: Check Wall where Vent will be Installed

There should be no plumbing or electrical wiring behind the wall of where the vent location will be, so first cut a small hole to check that nothing will interfere with the venting. If you find any plumbing or wiring, you'll want to consult with a professional, since you may have to vent through the roof. 

Note: If your vented range hood is going to be installed above a kitchen island, the vent will have to be installed in the ceiling and through the roof. Venting through the roof is a different process and may require a professional installation.

 

Step 5: Cut Interior Hole of the Vent 

If, after checking through the small hole you don't find any plumbing or wiring, you can proceed to cut out the bigger hole for your vent. With a jigsaw or keyhole saw, cut a hole that's at least six inches wide or slightly bigger if you want more room to work with. Next, with a long drill bit, place locator holes on the edges of the vent hole that extend to the exterior of the home. 

 

Step 6: Cut Exterior Vent Pipe Hole 

Using the locator holes as reference points, connect each dot with the pencil to form the circle that you'll be cutting out with the jigsaw. If the exterior of your home is paneled, you can use a piece of PVC trim to create an even surface to cut the hole through. 

 

Step 7: Attach the Duct/Range Hood Vent Cap

Attach the vent cap into the exterior opening, making sure that it's long enough to reach the range hood. Attach with screws and use the caulk gun and weatherproof caulking compound to get a tight seal. 

 

Step 8: Prepare the Damper

Some vent hoods are equipped with a damper. If yours has one, measure it against the interior hole to see how much space you need for the duct size. First use a small piece of duct to make sure you have the correct measurements prior to cutting the bigger piece of duct.  

 

Step 9: Run Electrical Wiring

Run the electrical wiring from the hood to the electrical box. If necessary, you can drill holes next to each side of the vent to make it easier to run the wiring. There should be enough conduit and wires from  the breaker to the hood's electrical terminal box. 

 

Step 10: Position New Range Hood and Secure Mounting Screws

With the second person that helped you remove the old range hood, place the mounting screws through the mounting slots of the hood. Next, remove the grease filter to give you better access to the screws when you tighten. Level the hood first, and tighten the upper screws before securing the bottom screws. 

 

Step 11: Finish Electrical Connection

Strip back the wires to connect them with wire connectors, making sure to clip any excess wiring. Match the color of the wiring to the corresponding color connector and the copper ground wire to the grounding wire connector. 

 

Step 12: Install Vent Covers 

Once the wiring has been connected, turn the power back on at the breaker box to make sure that the hood is working properly. Install the vent covers using your owner's manual for specific instructions. After this, your installation is complete!

FAQS 

CAN I INSTALL A RANGE HOOD MYSELF?

Installing a range hood yourself is a task that you can take on as long as you have the right supplies, full installation instructions for your model and feel comfortable with this kind of home project. Keep in mind that if your installation requires any rewiring, drilling a hole through the roof or moving plumbing, then hiring a professional is recommended.

DO RANGE HOODS HAVE TO BE VENTED OUTSIDE? 

Range hoods can either be vented outside or the air recirculated back into the home. Which one you choose depends on your kitchen setup and personal preferences. Vented hoods remove the air from your home, but ventless range hoods will also do a great job recirculating filtered air back into your home as you cook.

DO YOU NEED AN ELECTRICIAN TO INSTALL A RANGE HOOD? 

If you’re experienced with some home renovation projects and working with electrical wiring, then you may be able to install the range hood without hiring an electrician. However, if you’re not familiar with electrical work or don’t feel comfortable doing this kind of installation, then hiring an electrician is encouraged. 

ARE RANGE HOODS PLUGGED IN OR HARD-WIRED? 

While hardwiring your range hood is recommended, if your hood came with a three-pronged plug, it technically does not need to be hardwired.

CAN RANGE HOODS BE VENTED THROUGH THE WALL? 

You can certainly vent both wall range hoods or under cabinet hoods through the wall as long as there is a pathway to the exterior of the home. As a general rule, if you're using an interior wall and are creating a pathway, there should be no more than two elbows to your duct run and the length should not exceed 30 inches.
