Air Duct Cleaning questions, answered by experts

Air ducts should be cleaned every three to five years, though the frequency can vary based on factors such as household conditions and local environmental factors. For homes with pets, smokers, or high dust levels, more frequent cleanings every two to three years would be necessary to maintain optimal air quality. If you notice persistent odors, significant dust buildup, or signs of mold or rodent activity, schedule a cleaning sooner.

Odors, humidity problems, and health symptoms like headaches or allergies.

No, not all houses have ducts. It would be safe to say, however, that most modern houses do. The reason is that older houses had boilers in the basement that heated from the bottom up and often vents weren’t built into the house. Another reason is that older homes don’t have air conditioning (because it didn’t exist) and use radiators for heating. Since radiators don’t require ductwork, it wasn’t built.

Some experts say you should clean your air ducts every three to five years, but regular air duct cleaning is something you may never need to do. The EPA has shown no noticeable health benefits to cleaning your ducts regularly, so as long as you don’t encounter any major problems and maintain your HVAC system, you won’t need to clean your air ducts.

It’s possible to remove too much humidity from the air, but it’s very unlikely. Dehumidifiers have moisture sensors and settings to control how they function, so they can pause when the air inside your home reaches a certain humidity level. This means that most modern dehumidifiers won’t dry out the air to the point where it’s uncomfortable. But older, more basic dehumidifiers that are left on too long could potentially dry out the air so much that your skin, hair, and sinuses start to feel dry.
