A range hood removes odors, grease, heat, steam and smoke from the air in your kitchen during the cooking process. With a range hood, air will be filtered and the kitchen will be properly vented. Generally speaking, a range hood keeps kitchen space clean. As a result, more comfortable cooking environment is created.

On the other hand, a range hood can be a frustrating problem if it makes a lot of noise when working. There are many factors that affect range hood’s noise level. These include: materials used, size of a range hood, range hood’s exhaust fan, motor and others. Excessive noise can be caused by improper installation as well.

Range hoods can be either loud or quiet. Range hoods that come with variable speed controls and energy-efficient blower motors are quieter. A quiet range hood makes noise below 50 dB. A loud range hood makes noise above 60 dB.

And of course, it’s necessary to do something with a noisy range hood. If your range hood is very noisy, then you should try to make it quieter. There are many effective ways to reduce noise level in range hood. Today, we are going to share some practical tips that you should follow to make a range hood quieter.

So, let’s get started.

1. Inspect a Range Hood Carefully and Try to Determine the Causes of Noise

First of all, you turn on a range hood. Listen to a range hood carefully and try to figure out where noise in a range hood comes from. Keep in mind that range hood noise can be made by a range fan motor, ductwork or vibration. Once the source of noise is identified, you need to upgrade a range hood and fix a problem.

2. Soundproofing Makes a Range Hood Quieter

It makes a lot of sense to add soundproofing material to the interior of a noisy range hood. Among the best soundproofing materials for a range hood are: acoustic foam, fiberglass and vinyl. Such materials absorb sounds perfectly and make a range hood quieter. When adding soundproofing material, you should aim to cover as much area as it’s possible.

3. Clean or Replace Range Hood’s Filters Regularly

Keeping range hood’s filters clean makes a range hood quieter and has a positive impact on the quality of air. Grease, dust and dirt particles need to be removed from range hood’s filters. It’s necessary to clean or replace filters on a range hood regularly.

4. Clean Range Hood’s Blades Regularly

Dirt and debris can accumulate on range hoods’ blade over time. This negatively affects the motor. A motor becomes unbalanced and can make more noise. That’s why it’s so important to clean range hood’s blade regularly to prevent this from happening.

5. Tighten Range Hood’s Loose Parts

The same can be said about range hood’s loose parts. Keep in mind that range hood’s parts may loosen over time. Loose parts in a range hood cause vibration. As a result, a range hood begins to produce buzzing noises.

That’s why it’s necessary to check range hood’s loose parts from time to time. Pay close attention to the screws on blower and support screws in a range hood. Tighten parts on your range hood if such a need arises. Tightening range hood’s loose parts will help you reduce noise.

6. Lubricate Range Hood’s Moving Parts

All range hood’s moving parts have to be lubricated regularly. This has to be a part of range hood’s maintenance program. If you don’t lubricate moving parts in a range hood, they will become dry sooner or later. It’s one of the reasons why a range hood can make noise while working. However, it’s possible to avoid this problem. All that you need to do is to lubricate range hood’s moving parts properly. If you do this regularly, a range hood will always work smoothly.

7. Installing an External or Inline Blower

An external or inline blower would be a good addition to a range hood. A range hood works quieter with a blower. A blower can be installed either outside a house or within ductwork. An external blower is installed outside a house. Inline blower is installed within ductwork.

8. Make Changes to Ductwork

Sometimes, it’s necessary to make adjustments to ductwork to reduce the noise level of a range hood. If a range hood is too small, resistance will be created in the duct. So, it makes sense to increase the size of ductwork. Pick ductwork of a larger diameter for a range hood. By doing so, you’ll make it easy for air to go outside your home. When a range hood runs more effectively, it will be quieter.

9. Run a Range Hood at Lower Speeds

Keep in mind that the noise level of a range hood depends a lot on its speed. It’s possible to select a speed for a range hood. Range hoods come with a variable speed blower and have 2 – 6 speeds.

You can run a range hood at either high or low speeds. If you run a range hood at high speed, its performance increases. When you run a range hood at low speeds, its performance decreases but noise reduces. Lowering range hood’s speed helps lower noise. Increase and decrease range hood’s speed to find the golden mean between performance and noise.

10. Open the Door of Your Kitchen’s Cabinet

It’s the easiest way to make a range hood quieter. If range hood’s ductwork goes through kitchen cabinet, this method can help you reduce noise level. Open the door of the cabinets where your ductwork goes through. Sometimes, it’s enough to solve the problem.

As you can see, there are many ways to make a range hood quieter. Initially, you should understand what causes range hood noise. After that, you should take an action to make a range hood quieter. And of course, it’s incredibly important to maintain a range hood regularly. Doing regular maintenance works in time helps reduce noise level, makes a range hood quieter and prolong its lifespan.
