What affects the cost of duct cleaning?
Across the industry, these factors usually drive the price:
Number of HVAC systems
Many larger homes in Renton, Tukwila and SeaTac have two or even three HVAC units, often one per floor. Each unit has its own air handler and duct system, so per-unit pricing is a fair way to scale the cost. Our air duct cleaning is $199 for each unit.
Number of vents
Some companies charge per vent, which can add up quickly in a home with 15 to 25 registers. Our per-unit air duct cleaning includes unlimited vents on that unit, so you don't need to count registers to get a price.
Condition of the ducts
Heavy buildup, construction debris or pet hair can mean more time. If only one or two runs are the problem, targeted deep duct cleaning at $59 per vent may be the more economical choice.
Access
Ducts in tight attics, crawl spaces or unusual layouts can take longer to reach. We'll discuss any access issues during the estimate.
Add-on services
Dryer vent cleaning is a common add-on, since the equipment is already on site. It's $99 for up to 10 feet.
Watch out for bait-and-switch pricing
The FTC and the Better Business Bureau have warned for years about extremely low "whole-house" duct cleaning offers. The typical pattern is a very cheap advertised price, followed by pressure at your door to buy expensive add-ons or "emergency" mold treatments.
A few tips to protect yourself:
- Get the price in writing before work starts, including what's covered.
- Ask what the price covers: how many vents, which units, and whether returns are included.
- Be cautious of on-the-spot mold claims with pressure to buy right away. Ask to see the problem and take time to decide.
- Check reviews on Google and other platforms before you book.
- Ask about insurance and who will be doing the work.

Is duct cleaning worth it?
It depends on your home. Duct cleaning is most worthwhile when there's a clear reason: visible dust and debris, a recent remodel or new construction, pets, odors, or many years since the last cleaning. Customers often report less dust and fresher air afterward. Results vary by home, but removing buildup that restricts airflow helps your system do its job.
Dryer vent cleaning is often the easiest value to see: shorter dry times, less wear on the dryer, and lower fire risk from lint buildup.
