Range Hood Installation: Step-By-Step Instructions

Before knowing how to install a range hood (photo above), it is essential to understand what this kitchen appliance is and what it offers.

A range hood is an appliance designed to suck, filter, and vent gasses through its exit point.

These hoods can filter the air, odor, smoke, steam, and excess heat produced within your cooking area, whether you're preparing Gordon Ramsey's Beef Wellington or simple scrambled eggs.

Now that you know what it is, it's time to learn what you'll need and the specific steps to install a range hood through the following section.

What You'll Need

To efficiently install a range hood, the first thing you need to do is prepare the specific materials and tools, like the following:

  • Caulk gun, Chisel (optional), Drill
  • Drill bits, Ducting, Hammer (optional)
  • Hole saw, HVAC foil/aluminum tape
  • Oscillating tool, Pencil, Range hood
  • Screw, Screwdriver, Tape measure
  • Wall cap, Wire stripper, Wire nuts

After gathering the aforementioned materials, you must follow this step-by-step guide:

Step 1: Take Down the Old Range Hood if There Is One

The first step involves removing the old range hood and its embedded components if your goal is to upgrade it

However, if you do not have an existing range hood or you will be installing it in other parts of your kitchen, then you can skip this step and proceed with the second one.

Step 2: For Safety, Shut off the Electricity

Before drilling and doing other steps to install a range hood on the wall, you must first switch off the electrical power from the breaker box.

Turning the electricity off will keep you or an expert from the dangers of electrocution, especially when dealing with old or faulty electrical wiring.

Step 3: Hire Electricians for the Electrical Wiring Setup if There is None

The next step you need to do is to settle the electrical lines that will run the range hood by letting an electrician set it up. 

However, if you have existing wirings from your old vented range hood and there are no existing problems, pull the electrical cable, separate, and remove the protective paper to prepare it for connection in the later steps. Then, you can proceed to the next step.

Step 4: Measure and Mark the Vent Holes

After performing the first two steps, you must measure and mark the wall area where you will need to drill locator holes and set up the hoods.

Remember that this is only applicable for a ducted range hood (which is what most range hoods are) and not for the ductless range hood.

Nevertheless, you can do this by placing the round or rectangular duct at the chosen wall where you plan on mounting it and marking its diameter or area based on size.

Step 5: Drill or Cut Space for the Vent

When you have gotten the exact measurements of the range hood and the vent hole, it is time to drill or cut through the wall to make space for the vent.

In this process, you will need appropriate tools, such as the drill and drill bits. After preparation, follow these steps:

  1. For circular vents, use a hole saw to drill a hole for the ductwork inside
  2. For rectangles and other shapes, drill a hole through the wall using drill and drill bits
  3. You can also use the oscillating saw or a cold chisel and hammer to perfect the hole
  4. Check the wall entry points of the duct (flow)
  5. If there are obstructions, relocate the holes in the wall
  6. If there are none, proceed with drilling through the exterior wall

However, if you have ductless range hoods, it will not be necessary as they use a unique charcoal filter system to circulate clean air back into the kitchen.


If the obstruction includes pipes, plumbing, and wires, you can ask the help of professionals to relocate pipes accordingly.

Step 6: Install the Ductwork

The sixth step you must do is the process of installing ductwork. The duct is the pathway through which the air suctioned by range hood fans passes until it reaches the exit point.

In doing this, you must first put a mounting bracket (architecture) at the exterior hole using adhesive and mounting screws. After that, proceed with these steps:

  1. Connect the metal wall cap or duct cap with the end length of the ductwork (duct extension) using aluminum tape and screws.
  2. Then, install the connected ductwork into mounting brackets.
  3. Using mounting screws, secure the ductwork into the mounting brackets.

Now that you are done with the exterior wall, proceed by finishing the route (ductwork) on the interior by connecting the remaining duct length.

This is done by inserting it in the interior wall's hole using aluminum tape.

Step 7: Run the Electrical Wiring

After you install ductwork, it is time to connect and run the electrical wiring for your hood.

Using wire nuts, connect the electrical wires in the electrical box; this means black to black wire, white wire to white fixture lead, and green grounding wire to green lead.

Once all the wires are connected and in their proper places in the electrical box, cover the ductwork and electrical wire with the duct cover.


A duct cover or an electrical cover is essential to protect the internal electrical work, duct connector, and other materials from damage.

Step 8: Mount the Range Hood

When the ductwork has been settled, it is time to mount the range hood into your wall. In doing this, the following actions must be performed:

  1. Drill the mounting brackets into the wall, where the range hood will be attached based on the manufacturer's instructions, and fix them with mounting screws
  2. Secure the hood on the wall with screws driven at its intended spots on the top
  3. Cover the rest of the ductwork installed (seams) with a duct tape

Step 9: Turn on the Power and Test the Range Hood

When you have finished the first up to the eighth steps, you can proceed with the last (and most crucial step): turn on the electric power and range hood.

To check if the new appliance is working, here are the things you must watch intently:

  • If the hood runs when turned on (e.g., after plugging through an outlet nearby) 
  • If the lights are working properly
  • If the vented range hoods suction air
  • If the air passes swiftly out through the exterior wall exit point

  • How High Should a Range Hood Be?

    A range hood must be 20 inches to 30 inches above the heat source. Specifically, if you have an electric cooktop, ensure the range hood installation is 20 inches to 24 inches above.

    On the other hand, if you use a gas stove as a cooking surface, ensure you install the range hood at least 24 inches to 30 inches above.
