Cleaner Airflow

Get the Hidden Dust
Out of Your Home

Every time your system runs, air moves through your ductwork. When dust, pet hair and debris collect inside, some of it circulates back through your home. Professional cleaning helps remove it.

Frequently Asked Questions

Questions About
Air Duct Cleaning?

Find answers to common questions about the cleaning process, scheduling, airflow, and what to expect during service.

  • Many homes consider duct cleaning every three to five years. Cleaning may be needed sooner after remodeling, moving into a previously occupied home, or when excessive dust and debris are visible.

  • Removing accumulated debris from accessible ductwork may reduce the amount of dust moving through your air-distribution system. Household dust can also come from carpeting, furniture, pets and outdoor air.

  • Cleaning may reduce some dust, pet dander and pollen inside the duct system. It should not be presented as a medical treatment or a guaranteed solution for allergies.

  • Our equipment is designed to keep loosened dust and debris contained. The technician also protects work areas and cleans up before leaving.

  • Timing depends on the size of the home, number of systems, duct configuration and amount of buildup. We provide an estimated timeframe during scheduling.

  • In most cases, homeowners can remain in the home. The equipment may be noisy, so customers working from home or caring for young children may wish to plan accordingly.

  • Renovation and construction work can introduce sawdust and fine debris into vents and return-air pathways. A post-renovation inspection can help determine whether cleaning is appropriate.

  • Removing significant buildup may improve airflow and reduce unnecessary strain. We don't promise specific energy savings or utility-bill reductions.
