How to Replace a Range Hood

Whether you’re renovating your kitchen or you’re simply upgrading your range, installing a new range hood is a smart way to upgrade one of the most important appliances in the room. After all, range hoods effortlessly eliminate smoke, grease, and cooking odors from your kitchen while boosting ventilation at the same time. Learn how to replace a range hood in 10 easy-to-follow steps.

Pre-Installation Prep

1. Gather Tools and Supplies

Before you get to work, take the time to gather the tools and supplies necessary for this project. You’ll need the following:

  • New range hood
  • Circuit tester
  • Wire connectors
  • Wire cutter
  • Screwdriver
  • Screws
  • Masking tape
  • Pen
  • Safety goggles

Take the time to research permits in your local area, too. Although replacing a range hood might not seem like a big project, there’s a chance you’ll need one to do the job. Since that isn’t the kind of thing you want to learn after you’ve completed a project, do your research first.

2. Disengage the Power

When you’re ready to start, disconnect the power to the range hood. If you haven’t labeled your circuit breaker, you may need to flip a few switches until you locate the right one.

Since you’re going to be removing the wiring from the range hood in a few short steps, this is an essential safety precaution. Consider locking the panel box or leaving a note to warn your family members not to flip the breaker in question. Use the circuit tester to ensure the power is indeed disconnected before proceeding.

3. Detach the Old Hardware

Use the screwdriver to remove the hardware from the existing range hood. You’ll want to pull off all cover plates and filters and unscrew the lightbulbs. You’ll want to access the existing wiring before removing the hood from the wall, and you should be able to see and reach the wiring once you’ve detached the hardware.

4. Label the Existing Wiring Before Disconnecting

Next, take a few minutes to label each wire so there’s no question about how to connect the new range hood. Use the masking tape and pen to label each wire that extends from the wall.

If wire connectors hold any of the existing wires in place, unscrew them. If crimped connectors hold any wires in place, you’ll need to use the wire cutter to detach the two wires. Make a close cut to leave as much wire as possible to work with.

5. Remove the Old Range Hood

You’re finally ready to remove the old range hood, so use the screwdriver or screw gun to remove fasteners and other hardware that hold it in place. Although most of this project is a one-person job, you’ll want another pair of hands to help with this. Ask a friend or family member to hold the old hood in place while you remove the last few fasteners. It won’t be particularly heavy, but you won’t be able to support it safely while removing the screws.

Installing the Range Hood

With the old range hood out of the way, it’s time to focus on the new range hood. While it’s essential to measure the space before purchasing a new range hood, it’s smart to double check your calculations before moving forward with the installation.

6. Confirm the New Range Hood’s Dimensions

The new range hood should fit neatly into the horizontal space you have to work with while providing coverage for the width of the range. It should also leave at least 2 feet of clearance above the range. After all, you’ll want the range hood to pull smoke, moisture, and odors away from the range, but you’ll also want to leave plenty of space to cook.

7. Configure Venting and Wiring for the New Range Hood

Once you’ve confirmed the range hood specs, it’s time to prep the new model. Many newer range hoods can work with either overhead or rear venting configurations, so you’ll need to open the venting hole that matches with your existing ductwork. Remove any plates that cover the new range hood’s wiring, too.

8. Mount the New Range Hood

To mount the new range hood safely, review the manufacturer’s instructions. Your new model should come with its own set of mounting screws that are approved for the weight of the hood. To determine placement for the new range hood, ask a friend or a family member to hold it in place as you mark the correct location for the screws.

Move the new range hood out of the way and drive the mounting screws partway into the wall.

Put the new range hood in place, making sure it rests safely on the mounting screws. Make sure your kitchen ductwork lines up with the range hood’s vent, and then tighten the mounting screws.

9. Hook Up the Wiring

With the new range hood in place, it’s time to hook up the wiring for both the fan and the light. Thread the wires extending from the wall through the opening in the new range hood, and then match black wires together and white wires together. Use wire connectors to join black wires to black wires and white wires to white wires. If a ground wire extends from the wall, connect it to the grounding screw, which is typically green.

10. Finalize the Installation and Turn on the Power


To finish the job, tuck the wiring away neatly and put the wiring cover back into place. Check to make sure that all mounting screws are tight.

Switch on the power and then turn on the range hood to test it out. Make sure the light works properly, and check to be sure the fan is venting correctly. Step outside to confirm that air is flowing out of the exhaust vent for the range hood, since you won’t want the moist air from the kitchen to get trapped inside your house.

Once your new range hood is in place, the power is on, and the hood passes your tests, your kitchen setup is ready for use. Turn on your new range hood and get cooking.
