Things you need

Before proceeding towards installing your range hood, it’s better to get your hands on all the required tools and things which includes

  • A new Range hood
  • Drill bits
  • Noncontact electric tester
  • Power drill
  • Screwdriver
  • Wire nuts
  • Wire Stripper
  • Measuring Tape
  • Hammer
  • Dust mask
  • Hand gloves
  • Eye gear

Once you get all the things, then it’s time for action.

Remove old Rangehood

First things first, you need to remove the existing range hood in your kitchen. If your kitchen doesn’t have a range hood, you can skip this step and move to the next one.

For removing the range hood, simply detach the wires. For this, unscrew all the nuts and separate connections. Once you have unscrewed all the nuts, ask someone to hold the hood and take it off carefully. Be cautious not to hurt yourself.

Buy a new range hood

A range hood can impact your kitchen environment in a good or bad way, all depending on your choice. If your range hood is mismatched, it would be unable to filter out the heat and smoke. That is why it’s necessary to get yourself that range hood that fits your stove.

Here are here guidelines for that

  • Check the CFM rating of the range hood. CFM stands for cubic feet per meter, and it represents the air pulling ability of the vent. To calculate the best CFM rating for your kitchen, multiply the total square feet area by 2. The average cfm for most kitchen in 250 while if you’re looking for an excellent vent then go for 400 cfm.
  • Choose the range hood, which fits your stove perfectly. If you buy a shorter or longer vent, it can cause issues in the future. That is why it’s highly advisable to go for the right size. The average size for all stoves is 36in, 48in, and 60 in.
  • Some range hoods vent through the wall while others through a cabinet, If you’re buying a range hood for pre-existing vent pipe then make sure to the hood fits the venting pipe properly.
  • Measure the length of the stove and get the range hood with few inches extended than the actual size. This way, it will cover all the heat around the stove.

Disassemble the cover and filters

Now it’s time to disassemble the covers, filters, and fan of the range hood in order to fix them at the exact place. For that, make sure to switch off the electricity supply to the circuit.

First of all, remove the filters, you can easily remove the filters with hands and no tool is required.

Then, with the help of screwdrivers, remove the bottom panel. Next remove the duct connector, to prevent any damage, which is present underside the bottom panel.

Finally, with the help of a slotted screwdriver, take out the perforated knockout duct from the back end of the hood.

Prepare the vent

Now you need to prepare a proper vent for your range hood. But if you’re replacing an old hood, then there’s no need for this and you can skip this part. However, if you’re installing a venting range for the first time, you need to put some extra efforts.

Mark the Vent holes

Installing a new range hood under cabinet requires you to mark and draw holes. Most vent hoods come with a manufacturer’s guide/template for marking the right spot. You can use water or laser level to mark the exact middle spot on the wall. Then put your template on the mark and attach it with the help of a tape.

Once you have taped off the template. Now is time for drilling. Before drilling cross-check your markings because the cutout in the wall must the range hood knockout.

You can also drill for the wires, but I would suggest you not to do that if you’re not familiar with electrical wiring. You can take any expert’s help for that.

Cut interior hole

Before start cutting, check out if there are some pipings or wires behind the wall. If there’s nothing then with the help of a drill or wallboard saw, start cutting out the interior hole for the vent. However, if the wall has some kind of obstacles, below is the solution for that. (You can also take expert’s help if you don’t want to do it by yourself.)

Remove the obstacles

If there are pipings or studs in the wall, then you have to remove it. You can do it in three ways.

  • Re-locate the pipe somewhere else so that it leaves behind free space for drilling. It’s better to call a plumber for this job as you don’t want to break open a water or gas supply.
  • Cutout a few cleats from top and bottom of the wall. These will help the new wall patch and provides whole new wallboard covering the opening.
  • After that, drill and cover the hole with tape and mud. When it’s dry, drill the original cutout with help of the template.

By following this method, do the required ductwork. Install the ductwork in a way that it secretly reaches outside your home. Make sure to open the duct outside as it will not terminate inside the wall.

Install the hood

  • Just as you mark for vent with the help of the template, now mark for the cables and screws. You can also ask someone to hold the hood in place while you mark the holes.
  • Now drill all the holes for mounting brackets and screws.
  • If you’re drilling exactly into the wall, then drill the full screw in it, but if its cabinetry, then drill screws only halfway.
  • If you’re drilling in a cabinet, then it is recommended to use some wooden support on the back.
  • Once you drill the screws, check the alignment of your vent and holes.

Connect the wires

Now it is time for connecting the wires. For that, run the wire from inside the wall to the cable hood. Wires for fan and lights must be attached correctly. If you don’t know how to attach them, take an electrician’s help.

  • Connect one black wire from outside wall to two black wires inside the hood.
  • Repeat the same process for white wires.
  • Attach the green grounding wire to the grounding screw on the hood.
  • Then plug in your hood.

Reattach the filters

Reattach the filters and grease guard onto the hood. Then put on the lid with the help of screwers.

Turn on the power supply

Finally, turn on the power supply and check if the fan and lights are working well to ensure proper ventilation.

If your range hood is not working well, then it is highly advisable to call a professional. Don’t try to mess with it otherwise, it can get damaged.


  • Always wear protective gloves on hands and eye gear to protect yourself from any possible injury.
  • Don’t operate the drill if you do not know how to do that. Take someone’s help for this purpose.
  • Make sure to turn off all the electric supply before installing the under cabinet range hood.
  • Ask someone to help you in lifting and fitting the hood because it needs to be set in place perfectly.
  • Always buy the quality range hood to get rid of unnecessary mishaps.
  • Make sure to get the under cabinet hood because there are plenty of options available on the market.

What does a range hood do?

The range hood is one of the most essential appliances in your kitchenette. With the help of a filter and fan, it vents out the heat and smoke from your kitchen and circulates fresh air inside. The range hood is also best to keep your kitchen odor and fumes free. The range hood usually comes along with the stove, but if it doesn’t, you can purchase it separately.

How much does an under cabinet range hood cost?

On average, most under cabinet range hoods cost around $300 to $400. However, if you have a tighter budget, you can check for other range hoods at a lower price.

How much time is required to install a range hood?

It depends on the type and size of your range hood. Typically, it takes 1.5 hours to 2.5 hours in order to install the hood under the cabinet.

What is the difference between ductless and ducted range hood?

The ductless range hood doesn’t need to be vented outside. It blows the air out from the top and circulates it inside the kitchen. These hoods can be fitted anywhere and don’t need any ductwork.

The ducted range hoods need to be vented outside. These require ductwork and proper venting. Ducted range hoods remove air, smoke and fumes completely from the kitchen.


Which pipe is best for air ducting?

Any pipe which doesn’t melt under heat is perfect for air ducting. However, you must not use PVC pipes for this as they melt readily under heat.

At what height the range hood should be installed?

The average height for installing your range hood above the stove is 24 to 30 inches. If you install it lower than that, it could block the view. And if it is installed higher, the work efficiency can decrease.

But if you have a short height, then you can install it a bit lower. It all depends on how you feel comfortable.

Can I replace my old range hood with a new one?

Of course, you can replace your old range hood with a new, upgraded one. For that, check out the range hoods which fit under your cabinet perfectly.

Can I install a plug to my range hood?

If your range hood doesn’t come with a plug, then it is not recommended to install one. It could have safety risks. However, if you’re sure about it, then you can install the plug.

Does the fan continue to rotate if it is turned off?

No. If you turn off the fan, it will stop rotating.

Can I use the same hood range for gas and electric stove?

Yes, you can use any of the stove with under cabinet range hood. But make sure to install the hood a bit higher to the gas stove. Because gas stove gets hot faster than the electric stoves.

Why my range hood produces so much noise?

Some range hoods have loud voices while others have less to no sound. It all depends on the placement of the fan motor. If the unit blower is located inside, it produces annoying noise. So always check the manual carefully before purchasing a vent hood. Otherwise, you will be left with frustrating sounds in your kitchen.
