One of the biggest complaints about kitchen ranges is the noise level. The most obvious way to have a quiet range is to buy one with lower noise output.
Even if you don't want to replace your current setup, there are a few ways that you can decrease noise and enjoy a quieter range:
Use the lowest speed: Running your over-the-range unit at the lowest speed setting will provide you with a quieter noise output.
Choose a unit with an inline blower: Inline blowers produce the least amount of noise when compared to other motor types.
Keep the hood insert and filters clean: The cleaner the hood insert and filters are, the quieter the unit will be.
Secure all unit parts: Running a fan at top speed with loose parts will lead to a loud rattling noise that will get frustrating fast. Make sure all parts are securely tightened.
Routine maintenance is an important part of reducing noise and improving performance.
