How Often Should Air Ducts Be Cleaned?

When To Clean Your Air Ducts

Most people don’t think very much about the air ducts that help heat and cool their homes.  Many assume they’re not something that needs to be looked at unless blocked off or not passing air for some reason. But knowing how often to clean air ducts should be like knowing when to check other major components of the home.

So how often should air ducts be cleaned? According to the National Air Duct Cleaners Association, the general time frame should be every three to five years.

Respiratory Conditions

If there are people living in the house who have respiratory conditions such as asthma or who have severe allergies related to dust and mold, it may be advisable to have a somewhat shorter window on the order of two to three years. Annual cleanings, if they’re logistically feasible, can certainly be arranged, but there’s a distinct chance of diminishing returns.


One of the big misconceptions about air duct cleaning, in Phoenix and elsewhere, is that the ducts shouldn’t be able to hold on to dust, that the force of the air pressure is enough to keep it from settling.

In fact, dust sticks to all sides of an air duct, picking up a weak static charge as it travels, helping it stick to the metal inside of most ducts. And once it sticks, it’s going to stay stuck until something disturbs it like a duct-cleaning brush. The same properties apply to things like dust mites, mold spores, and pet dander.

If you’re going to hire air duct cleaners in Phoenix, or anywhere for that matter, make sure that you’re hiring professionals. Check to make sure that they’re members in good standing with the National Air Duct Cleaners Association and that they adhere to NADCA standards when it comes to their work.
