What We Remove
Dirty Filters Are Just the Start
A clogged filter is a visible symptom — but the buildup inside the duct network is what drives air quality issues and system strain. We clean the full system, not just the accessible surfaces.
After cleaning, filters last longer and the system runs more efficiently. Most homeowners notice improved airflow and reduced dust within days.
What's Included in Our Cleaning
Supply duct cleaning
All supply lines from the air handler to every vent register, cleared of dust and debris
Return duct cleaning
Return air lines that pull stale air back to the HVAC unit — often the most contaminated portion
Air handler cleaning
The internal components of the air handler including the blower wheel and evaporator coil area
Register and grille cleaning
All supply and return registers removed, cleaned, and reinstalled
HEPA vacuum containment
We use HEPA-filtered vacuum systems to capture and contain debris rather than releasing it into your home
Pre and post inspection
We photograph before and after to show you exactly what was removed

The EPA and NADCA (National Air Duct Cleaners Association) recommend air duct cleaning every 3–5 years for most homes. Clean more frequently if:
- You have pets that shed
- A household member has asthma or allergies
- You've recently completed home renovations or construction
- You've moved into a previously owned home and don't know the cleaning history
- You've had water damage or noticed mold near registers
- You have a very dusty home despite regular cleaning

Bundle & Save
Many Seattle homeowners bundle air duct cleaning with chimney cleaning or dryer vent cleaning for a complete home ventilation service. The duct-plus-dryer-vent pairing is our most requested combination for air duct cleaning in Renton, where many 1960s–90s homes are due for both at once. Ask us about our bundle discount — you can save $50 when you combine services.
Time to Call — 5 Warning Signs
These are the signals your air duct system is overdue for a cleaning.
You need to dust more than usual
If you find yourself dusting furniture every few days — even with windows closed — your ducts are likely redistributing accumulated debris with every HVAC cycle.
Higher utility bills
Restricted airflow caused by duct buildup forces your HVAC unit to run longer to reach target temperatures. If your heating or cooling costs have crept up without explanation, dirty ducts may be the culprit.
Allergy or respiratory symptoms
If family members experience increased sneezing, coughing, or allergy flare-ups that improve when they leave home, contaminated air ducts circulating allergens and mold spores could be a contributing factor.
Little or no airflow from vents
Registers that barely push air — or pull noticeably less than others — suggest significant buildup in those duct runs, or a blockage. This puts added strain on your HVAC system and reduces efficiency throughout the home.
Musty or stale odor when HVAC runs
A smell that appears only when the furnace or AC kicks on is a strong indicator of mold growth, dead insects, or significant debris accumulation inside the duct system. This warrants prompt inspection and cleaning.
You can see debris at the registers
Visible dust buildup around your supply or return registers — especially dark streaks on surrounding walls — means contaminants are actively being discharged into your living space.
Benefits of Clean Air Ducts
Regular air duct cleaning pays for itself in energy savings, HVAC longevity, and improved home air quality.
Cleaner Indoor Air
Remove allergens, mold spores, pet dander, and dust particles that recirculate with every HVAC cycle.
Lower Energy Bills
Clean ducts allow unrestricted airflow — your HVAC reaches target temperature faster and runs less.
Longer HVAC Life
Reduced strain on the blower motor and heat exchanger means fewer repairs and a longer system lifespan.
Less Dusting
Less debris in your ducts means less debris blowing out of your registers and settling on surfaces.
What Is Air Duct Cleaning?
Air ducts are the network of channels associated with your HVAC system — the heating and cooling system in your home. These ducts carry conditioned air from your furnace or air handler to every room, then return it back for reconditioning.
Over time, these passages collect dust, pet dander, pollen, mold spores, construction debris, and other contaminants. Every time your HVAC runs, it pulls from and pushes into these ducts — recirculating whatever has accumulated inside throughout your home.
Professional air duct cleaning uses specialized rotary brush systems, high-powered vacuums, and compressed air tools to remove built-up debris from the full duct network — from the air handler to every supply and return register in your home.
