Ventilation in a kitchen is essential because, in addition to keeping the kitchen cleaner, it helps prevent the smell of food from flooding the house and cleaning the air you breathe. Options for keeping the kitchen ventilated are an open window and an exhaust hood. There are two types of kitchen hoods, those that have a duct that communicates with the exterior of the house and those that recirculate the air, cleaning the environment.

Although both types have the same goal in common, the operation is not the same. For example, those that are connected to the outside, purify the air with the help of a fan that is connected to a filter and a tube that leads outside the house. The other type, the recirculating one, cleans the air through a carbon filter and returns the air to the kitchen. 

These two types are adapted to particular needs, as there are many models of each one that is adjusted to the sizes and proportions within the kitchen. Both types are easy to install and simple to maintain. To install a kitchen hood, just follow these simple steps.

How to Install a Range hood?

To install a kitchen hood, you first have to know which of the two you need. This decision will be very simple, because if you have a tube that connects to the outside of the house, you need a hood that has these characteristics. If there is no such installation in the kitchen, the best and most practical thing is to have an air recirculation system.

Regarding the space that is needed, before installing a kitchen hood, the area in which it will be placed must be larger than that of the stove, that is, the optimal thing for good cleaning is that the hood is larger than the cooking zone so that the extraction is carried out in the most efficient way. If for space, the dimensions are equal, no problem.

Regarding the height at which we are going to install a kitchen hood, it is recommended that it be at a distance of between 65 and 70 centimeters from the cooking zone and about 55 or 60 centimeters if they are induction, glass-ceramic or electric stoves.

Materials and Tools to Use

After having taken the necessary measures and having bought an extractor that fits the needs of the home, check to have all the materials and tools to use to install a kitchen hood.

What Do You Need?

  • Bubble level
  • Measuring tape
  • Drill and bits
  • Arrow bit (only if tile needs to be drilled)
  • Stripping pliers
  • Screwdriver
  • Hammer
  • Dowels
  • Insulating tape
  • 1.5 mm electric cable.
  • Bolts
  • Pencil
  • Bell
  • Flexible duct with accessories (in case of having the outdoor outlet installation)

Measure the Area to Install a Range Hood

All range hoods have back holes that are used to hang them on the wall. You have to find them and measure the distance between them. The idea is to place marks on the wall and then make the holes with the drill.

One recommendation is to take a sheet of paper and mark it with a pencil. The sheet is folded in half and glued to the wall to make those same marks. With these visual guides, more precise holes can be made with which we will fix the hood to the wall.

Make the Holes in the Wall

Following the guidelines marked on the wall, we will prepare to make the holes in the wall. To do this, we must choose the drill that best suits our needs according to the thickness of the screws that fix the kitchen hood and the type and material of which the wall is made.

If the kitchen wall is tiled, an arrow point bit should be used so as not to break the ceramic. Once the tile has been drilled, it should be continued with another bit, either for concrete, brick or wood.

This is one of the steps in which there must be more concentration and precision since the correct fixing of the kitchen hood to the wall depends on doing this step well.

Electrical Installation

The Range hoods have an extractor that works with electrical energy so it must be connected to the current. If we are going to replace a hood that was already installed, the electrical connection is probably already made. If not, one must be created, for which we will need a plug.

The main thing is safety. Turn off the electrical power in the kitchen and locate the closest electrical outlets. If needed, strip the wires with the pliers and cut them for an outlet. It is important to connect the positive cables with the positives and the negatives with the negatives. You should always use the insulating tape to not leave cables uncovered, once we have finished.

Place the Anchors, & Screws Clamping Guide, and the Bell

We must hammer the anchors into the wall and then place the screws and the fastening guide with the screws inside them, tightening them as much as possible with the screwdriver. If the hood does not have a fixing guide, place the part of the hood that will be fixed to the wall.

Placing Screw of Range Hood

Once the fastening guide has been placed, we must assemble the hood with the guide and make sure that it is firm. If the hood is air recirculating, we just have to connect to the electrical current and that’s it. If not, go to step 5.

Fit the Exhaust Pipes

If the installation of our kitchen has an exit to the outside, the exhaust pipe must be installed. The flexible duct must be in contact with the kitchen hood on one side and with the outlet on the other. For them, we must put it as much as possible into the outlet hole, and at the other end, it must be fixed to the air outlet of the hood.


Range hoods work with filters to clean the air, so it is very important to check the hood filter periodically to make sure it is always in the best possible condition. The filter is very important because it is the one that keeps the grease and odors, so you have to be vigilant to change it regularly.

In addition, being in contact with the fat that comes off the cooking zone, it is common for it to fill with grease, so in addition to changing the filters regularly, the inside of the kitchen hood must be kept clean.
