The frequency for cleaning air vents can vary. As a general guideline, you should inspect and clean your return air vents at least once a year, while a more thorough cleaning of all vents is recommended every two to five years. However, you should clean them more frequently if you notice a significant buildup of dust or debris on the vents, see mold growth, find signs of a pest infestation, or notice an unusual amount of dust accumulating on your furniture. More frequent cleaning may also be necessary to maintain good indoor air quality if household members have allergies.
