Exhaust fans are designed to remove water vapor, foul odors and smoke from bathrooms and kitchens. An exhaust fan pulls these things out of your home and passes them to your homes duct system to the outside. However, there may come a time when you notice the exhaust fan in your bathroom or kitchen is no longer quite as strong or as effective as it used to be. So, if you notice that your exhaust fan is no longer able to move air the way it once did, there are a few things that you should do.
Giving Your Exhaust Fan More Power
If you notice your exhaust fan is not working the way it should, remove the fan cover and thoroughly clean the fan blade and enclosure. Over time, dirt and grime can build up on the blade and enclosure that will reduce the effectiveness of your exhaust fan.
Next, check the area in your attic around the exhaust fan and check for any obstructions to the airflow of the exhaust fan. Check to make sure that duct system is intact and nothing is impeding the flow of air from your exhaust fan to the outside of your home. You may have to occasionally remove duct tube from your exhaust fan and shake it out and remove any debris that may be blocking air flow.
