Licensed, bonded & insured in WashingtonMon–Fri 8am–6pm · 24/7 emergencies
Duct cleaning removes dust, pet hair, and construction debris from your home's supply and return lines, register boxes, and the air handler compartment. It's typically needed every 3 to 5 years, or sooner after a remodel, pest issue, or if you're noticing more dust on surfaces than usual. We serve homes throughout King and Snohomish counties, from older Seattle bungalows to newer builds in Redmond and Lynnwood.

How a duct cleaning visit works
1
Inspection
We check accessible duct runs, registers, and the air handler to gauge debris buildup and note any damage or disconnections before starting work.
2
Sealing and setup
Registers are covered and equipment is staged to contain dust so it doesn't spread into living spaces during the cleaning.
3
Vacuum extraction
A high-power vacuum system pulls dust, debris, and allergens out of the main trunk lines and branch ducts.
4
Agitation and brushing
Stubborn buildup on duct walls is loosened with brushes or air whips before final extraction.
5
Final walkthrough
Registers are reattached, the work area is wiped down, and we review findings with you, including any duct repairs worth considering.

Straight answers
Duct Cleaning questions we hear most
How long does duct cleaning take?
Most homes take 2 to 4 hours depending on the number of vents and how the ductwork is routed. Larger homes or systems with heavy buildup can take longer. We give you a time estimate on-site before starting.
Will duct cleaning lower my energy bills?
It can help if ducts were significantly clogged, since restricted airflow makes your furnace or AC work harder. For most homes the bigger benefit is cleaner air and less dust, not a dramatic bill drop.
Do I need duct cleaning every year?
No. Most homes in King and Snohomish counties only need it every 3 to 5 years unless there's a specific trigger like a renovation, pest problem, or new pet allergies in the household.
Is duct cleaning messy?
We seal registers and use contained vacuum equipment to keep dust out of your living space. Some residual dust settling near vents is normal afterward and easy to wipe up.
