How Often Should You Clean Your Air Ducts and Vents?

By Luke Armstrong

Take a deep breath… and exhale. Did that hurt your lungs at all? If you have not had your air ducts and vents cleaned in a while, you may be harming your health and you don’t even know it.

While the immediate damage may be as simple as additional sneezing, it can extend to prolonged allergic reactions to dust and mold and eventually, a respiratory infection. Air ducts and vents carry and filter cold air and warm heat through your home and office throughout the year. Just as the air filter in your vehicle and the lint trap in your dryer must be replaced or cleaned, the same attention must be paid to your air ducts and vents.

Duct CleaningThe question remains…how often should you clean your air ducts and vents? Having your heating and cooling system cleaned as a preventative measure is wise in response to certain events. Examples of these events include:

1. You think that water has entered your ductwork.
This can occur if your roof begins to leak or a pipe bursts.

2. Your air conditioner condensation drainage system malfunctions.
This water may collect and harbor mold.

3. There was a nearby forest fire or industrial fire.
Ash and soot can settle into your heating and cooling systems.

4. You experienced flooding in your house or in your area.
Moisture may have settled into your ventilation system and can trap allergens in your home.

5. You recently did a home remodeling or home improvement project.
Drilling, resurfacing and replacement of tiles and flooring may kick up dust in your home.

6. You resolved an insect or rodent infestation.
It is best to consult a professional duct cleaner to ensure all traces of this issue have been removed.

7. You are moving into a new home.
You may not know what the previous owners’ habits were, so it is wise to have the ducts cleaned before you move in.

8. There is visible mold growth in your vents or you smell mold or mildew in the ducts.
It is possible the problem has spread to other areas of your home, which means it’s time to call in a professional.
