Let’s talk on how to install under cabinet ductless range hood today.

Installing a Under Cabinet Ductless Range Hood: Required Tools & Installation Guide

I’ll elaborate simple steps of how to install a range hood under cabinet, the ductless version of course. You’ll need some tool for the project and I’ll start by mentioning those.

Tools & Materials

  • A work box.
  • Circuit testes.
  • An electric outlet.
  • Mallet
  • Saw for drywall.
  • Wire stripper.
  • Screwdrivers set.
  • Drill
  • Drill bits of 1/8 inch size.
  • Drywall screws of 2-inch size.
  • Tracing paper
  • Stud finder.
  • Tape measure.
  • The Range Hood.

Determining the Wall’s Center

Start by putting a cardboard over the top of range. So that you can protect it from the consequences of this process. You need to figure out the wall’s center point by using tape measure. If this installation space is between two above-cabinets, then this mark should be exactly halfway from each of these.

It should be exactly centered above the range to ceiling, try double-checking to ensure that. As soon as you find the center, get a level. Use it for drawing a vertical line from the ceiling’s range.

Getting the Measurements Right

Usually, with range hoods, recommendations are coming along to make the placement right. Usually, these come with 29 to 34 inches above range mounting setup. You should decide where the chimney and range hood will be placed by taking these measurements of available space. Just make sure that after positioning the hood, recommended height is above range.

Let the chimney be on top of the range hood. Calculate the distance between range hood bottom to chimney’s top part. The chimney should be at its shortest length. This distance needs to be less than range hood’s bottom to ceiling distance.

Or else there’s a chance of mounting range hood lower on the wall. Between the ceiling and range hood’s top, electric wire for outlets need to fit nicely. With this measurement you are goal is to be sure about the range hood’s bottom and top part placement accurately.

Setting Up the Electrical Box

You need to place the old work box in a face-first position against wall. This placement should be on the space where wires emerge. Markdown the opening where this box will fit by simply tracing edges around. It should be somewhere close to center line and the area that chimney will cover.

You should have the right breaker off. Use a circuit tester to check that. Once you are sure about wires being live, switch off the circuit controlling this breaker. Now along the pre-marked line, use a drywall saw to make a cut. Start through a small hole to be safe in this process. You can look for wires and other obstruction while going this way.

Use a mallet to tap out the drywall. On old work box’s back, you need to pry open the holes. Thread down the circuit wires through these holes. After inserting wires, place this box into the wall opening. Let the screws be tight enough so that placement is secure enough.

Connecting Wires

Use a wire stripper to strip around half inches from each insulated wire. Make a tight J shape by bending the exposed ends of these wires. On the electric receptacle, there should be brass-colored screws. Make it lose and loop this J shaped black wire.

It should be around the brass screw and use a clockwise direction here. Tightly attach the screws. Use the same manner to attach white wire into sliver screws. Finally, connect the bare copper ground wire to green colored.

Now gradually tuck these wires inside the box. You don’t want to loosen any connections. Use mounting screws next and connect straps of outlet to the box. Turn on the power and test if it works. Troubleshoot for any mistaken step and finally connect the cover plate.

Placing Bracket

Get to the range hood’s back part and hold a tracing paper. This is where you need to make the mounting bracket holes. Trace down these holes into the paper. You want to redo measurements if necessary. Markdown the spots where these drywall screws will go through.

Use the 1/8-inch bit and drill to make pilot holes into marked spots. Insert the screws and tighten them. Stop when screws are barely protruding. These screws will hold the hanging range hood.

Now you need to add those chimney brackets next. Place them directly on the ceiling and center line using drywall screws.

Fixing Range Hood & Chimney in Place

Over the mounting screws, slip range hood and tighten them securely. You need to determine two studs that run behind range hood. Use stud finder for that. From beneath of hood, anchor it to the studs at marked lines. Since the marks are beneath hood, it won’t be visible. Plug the range hood into an electric outlet and check if everything is working fine.

Now you can finish by placing chimney. Just slip it over the mounting hardware located on range hood. There’s no need to insert anything inside the chimney. Use provided screws to secure the chimney with range hood’s body.

And We Are Done with The Installation!


And now you have the whole guide on how to install under cabinet ductless range hood. Ductless hoods are surely super versatile and easy to use but only with the right installation.

Also, don’t forget to check your local building codes. Since you’ll be dealing with electrical work, this follow-up is necessary to keep things legal.

Good Luck with The Installation!

  1. Hello, your article provided some very useful information that really comes in handy. However, I do disagree with your suggestion of stripping the electrical wires yourself; many would suggest that a certified electrician do this instead. Most people are inexperienced when it comes to stripping wires, and if done incorrectly, or the wire is nicked even slightly, the wire will overheat easily and start a fire. I would not recommend that this part of the range hood installation be done as a DIY step.

    • I agree with you. I also recommend hiring certified electricians to do this job. This guide is only for those people who dare to do DIY work, know what are they doing, and have confidence in themselves.

      Thanks for your valuable opinion.
