What air duct cleaning actually involves

First question: do you have ducts? Census estimates show electricity as the main heat in 61.1% of Seattle's occupied homes, and much electric heat (baseboards, wall heaters, ductless heat pumps) uses none. Ducts belong to forced-air furnaces and central heat pumps. Fuel oil remains the main heat in 8.0% of occupied homes in the Census ZIP code area around Arbor Heights, the highest share among the peninsula's areas, though that area also reaches past the city limit. Older furnaces often sit on duct systems that have not been opened in a long time. We clean those systems under negative pressure, so that what is loosened leaves the house instead of the registers.

Indoor air has been designed for on the peninsula before. When the Seattle Housing Authority rebuilt High Point, its 1,529 on-site units included 60 'Breathe-Easy' homes designed to reduce asthma triggers. Most houses were not built with that aim, and in one with a forced-air furnace the return ducts running through a crawlspace or basement are a common place for dust and damp to get in. Our inspection starts there.

What's included

  • Inspection of the furnace, the plenum and a sample of ducts before any work, with photos
  • A negative-pressure collector hooked to the trunk line and exhausted through HEPA filtration or outdoors
  • Each supply and return branch agitated with air whips or brushes toward the collector
  • Registers and grilles removed, washed and refitted
  • Blower compartment and accessible plenum cleaned, and a new filter fitted if you have one on hand

Why it matters

Smoke has made indoor air a practical topic. When smoke settles in, the Puget Sound Clean Air Agency suggests a HEPA filter, a furnace filter of MERV-13 or higher strapped to a box fan, one room set aside as the clean room, and closing the fresh-air intake on an air conditioner. A forced-air system can help or hurt in those weeks: with a good filter and clean returns it circulates filtered air; with a clogged filter and dusty ducts it redistributes what is already there. Duct cleaning is one part of that, and the filter is the larger part.

Candor matters with this service, because it is often oversold. Cleaning is worthwhile when there is visible debris or construction dust in the ducts, signs of rodents or insects, mold growth on hard duct surfaces, or dust blowing from the registers. It is not a routine annual need, and it does not cure a damp crawlspace or a leaking duct. If we find disconnected runs, crushed flex duct or wet insulation under the house, we photograph them, because those are repairs to make before any cleaning.

How it works

What to expect with air duct cleaning

  1. 1

    Look first

    If the ducts are clean, we say so. Not every system needs this.

  2. 2

    Seal and connect

    Registers are covered and the collector is attached, putting the whole system under suction.

  3. 3

    Work branch by branch

    Starting at the register, every run is agitated toward the trunk.

  4. 4

    Clean the air handler side

    Blower, return drop and plenum are vacuumed.

  5. 5

    Show the result

    Duct interiors photographed at the start and again at the end.

Signs you may need air duct cleaning

If any of these sound familiar, book the $99 plus tax inspection — credited toward the work if you approve the quote:

  • Dust puffing from the registers when the furnace starts
  • Debris, pet hair or construction dust visible behind a removed register
  • Evidence of rodents in the crawlspace, or droppings in a duct
  • Drywall work, floor sanding or a remodel carried out while the furnace was running
  • A stale odor present only while the blower runs

Air Duct Cleaning — common questions

What will air duct cleaning cost for my house?

For ducts our price is from $535. How many registers there are, how large the house is and how reachable the trunk lines are set the figure, which we confirm after seeing the system.

How often do ducts need cleaning?

Only when an inspection shows a reason: debris, pests, mold on hard surfaces, or dusty construction. Changing the filter on schedule does more for most homes than frequent cleaning.

I have ductless mini-splits or baseboard heat. Do I need this?

No. Those systems have no ducts. Mini-split heads have washable filters and occasionally need a coil cleaning, which is a different service from this one.

Do you spray sanitizers or sealants into the ducts?

Not as a routine. We remove debris mechanically. If mold is found on duct surfaces, the moisture source has to be fixed first, and we talk through the options with you case by case.

Can the dryer vent be cleaned during the same appointment?

Yes, and the two are often paired. The dryer vent is a separate exhaust with its own tools, priced apart at $105–$295.
