Range Hood Maintenance


Range hoods were not always necessary but with the advancements in cooking, they have become one of those kitchen essentials. If you are constantly cooking meals that produce a lot of smoke then a range hood might be the best way to keep odors from lingering around your home. Just like most appliances, there are many sizes, styles and designs to choose from but the maintenance of these products are relatively the same.

Range hoods must be placed over the range in your kitchen about 25-30 inches above the surface. It is alright if the range hood hangs a little over the side of the range, this will help rid of smoke and odors more efficiently. You must choose the correct direction for venting and properly connect the wiring in order for the range hood to be installed correctly. Note that the CFMs of the hood should be at least 1% of the total BTU output of the range for optimal performance. So, if u have a range that is 30000 BTUs, then the range hood must be at least 300 CFMs in order to properly vent

It is advised to have a professional install your range hood. However, if you have the knowledge and materials to do so yourself, by all means, blow em’ away!


Cleaning the air filter on your range hood is important in keeping the air clean in your kitchen. There can be either a metal or charcoal filter in your unit. Both of these kinds of filters can easily be removed and cleaned or replaced. If you have a metal filter, remove it and place it in a degreasing solution. Once you see that all of the grease and dirt has dissolved, thoroughly wash the filter in soapy warm water and let dry completely before placing the filter back in its place. If you have a charcoal filter, simply remove and replace it (charcoal filters are not washable). You must replace/clean these filters at least twice a year or when you feel as though it is losing its power.

Cleaning the vent of your range hood is often forgotten and this neglect can be hazardous to fire. The grease build up in the vent comes from using the range hood, as the same for the air filters. If it helps, when you check your air filters, check your vent’s condition as well. If it needs cleaning, contact your local cleaning professional as soon as possible.


Cleaning the fan or replacing the motor goes hand in hand because sometimes you may think the motor is faulty but, the fan just needed to be cleaned because of built up dirt and grease. If an issue does persist, try cleaning the fan first. If this does not solve the problem, then you will need to replace the motor.

Cleaning the whole unit itself will keep it looking brand new and will get rid of any residue that may be left on the surface from previous meal preparation. Use a household cleaner or degreaser and a non-abrasive sponge or rag to wipe the range hood clean. Be careful to steer clear of electrical components when spraying the cleaner.


Testing your range hood is a great way to determine the condition of your range hood. A simple test of holding a piece of paper near the vent can be conducted to check if your vent is running normally. If the piece of paper is suctioned upward and held, your range hood seems to be working as it should.

Paying attention to some of these signs will tell you whether or not you need to have your unit repaired:

  • The motor is making odd sounds or unknown sounds occur
  • The controls and/or lights stop working
  • The suctioning of smoke has reduced

If you practice these tips when you should, it will help your range hood last longer.
