For Improved Air Quality:

We recommend that your ducts be cleaned at least once every 3-4 years to ensure the most effective operation of your heating and cooling systems.

How often you decide to have your ducts cleaned depends on several factors such as:

* moving into a new home
* renovations or remodeling done to your home
* having smokers in your home
* having pets that shed high amounts of fur and dander in your home
* family members with allergies or asthma who might benefit from a reduction in the amount of indoor air pollutants in your home
