What does air duct cleaning include?
- Inspection of the supply and return ducts, the blower and the coil, to see what is actually there: dust, debris, pet hair, construction dust or signs of moisture.
- Cleaning each run, loosening and removing the dust and debris inside the ducts.
- Registers, returns and grilles removed and cleaned.
- The system side: the blower and coil, where dirt does the most harm to airflow, and the filter and how well it fits.




When duct cleaning helps, and when it does not
The US EPA advises cleaning ducts when there is visible mold growth, signs of rodents or insects, or so much dust and debris that particles blow out of the registers, and not as routine maintenance on a clean system (EPA). Good reasons to clean in Los Angeles homes:
- After a remodel, drywall work or flooring sanding.
- After wildfire smoke or ash got into the system.
- Moving into a home where pets or smokers lived.
- Dust blowing out of vents shortly after you clean, or a musty smell when the system starts.
If the ducts are torn, crushed or disconnected, cleaning will not fix them; see air duct replacement.

How often should ducts be cleaned?
Only when one of the reasons above applies; for most homes that means years apart. Changing the filter on schedule, every one to three months depending on the filter and pets, keeps ducts clean far longer. Better filtration is covered on indoor air quality.

What affects the cost of air duct cleaning?
The number of supply and return vents, the size and layout of the home, access to the attic or crawl space, how dirty the system is, and whether the blower and coil need cleaning too. Every quote is up front with no hidden fees, and same-day and scheduled air duct cleaning is available.

Air duct cleaning questions
Is air duct cleaning worth it?
It is worth it when there is a reason: visible debris, mold, pests, a remodel or smoke. On a clean system with good filters, the money is better spent on filtration or duct sealing.
Does duct cleaning help allergies?
It removes dust that has built up in the ducts; ongoing allergy relief comes from better filtration and sealed returns. See indoor air quality.
