How often should air ducts be cleaned?

Every 3 to 5 years for a typical home. Every 2 to 3 years is better with pets, smokers, or allergy sufferers, and ducts should be cleaned right away after renovation work or wildfire smoke exposure.

Does duct cleaning need to happen every year?

No. Annual duct cleaning is unnecessary for most homes. Dryer vents are the annual item; ducts run on a 3 to 5 year cycle unless something changes in the home.

Should I clean the ducts in a newly built home?

Yes. New construction and remodels leave drywall dust, sawdust, and insulation fibers inside the ductwork. Cleaning before or right after move-in clears that out before it circulates.

How often should I change my HVAC filter?

Every 60 to 90 days for a standard 1-inch filter, or monthly if you have pets or allergies. Thicker media filters generally last 6 to 12 months.

How Often Should You Clean Your Air Ducts?

There is no single answer that fits every home. Pets, allergies, remodeling, wildfire smoke, and system age all shorten the interval. Here is the schedule we recommend after twelve years of cleaning ducts across California.

Immediately

After renovation or smoke

The baseline: every 3 to 5 years

For a typical home with no pets, no allergy sufferers, and no recent construction, cleaning every three to five years keeps dust, pollen, and debris from building into the airflow. That matches the National Air Duct Cleaners Association guidance and what we see in the field.

Recommended schedule by home type

No pets, no allergies: every 4–5 years
One or more shedding pets: every 2–3 years
Allergy or asthma sufferers in the home: every 2 years
Smokers in the home: every 2 years
After remodeling, drywall, or flooring work: as soon as work finishes
After wildfire smoke exposure: same season
Newly purchased home: before you move in
Rental turnover: between tenants

Signs you are overdue right now

Visible dust puffing from vents when the system starts
Dust resettling on surfaces within a day of cleaning
Musty or stale odor when heat or AC runs
Allergy symptoms that get worse indoors
Uneven airflow between rooms
Rising energy bills with no change in usage
Mold, pet hair, or debris visible inside a register

What about filters and coils?

Duct cleaning is not a substitute for filter changes. Replace a 1-inch filter every 60 to 90 days, or monthly with pets. Media filters typically run six to twelve months. Have the blower and evaporator coil inspected annually — a dirty coil undoes the benefit of clean ducts.
