Delridge, King County
Cleaning the forced-air ducts in a Delridge home starts at $535. Three things move the number: the count of registers and return grilles, the length of the main trunks, and whether those trunks hang in a crawl space or attic we can get into. A powerful collector clamped onto the trunk keeps the whole system pulling inward, and only then do brushes and air whips start knocking dust loose, so it travels to the collector rather than into the living room.

Not every home here has ducts to clean. Ask the Census which fuel warms the houses in Delridge's ZIP code area and electricity wins: it is the main source in about 63 percent of occupied homes, and electric heat often means baseboard or wall units with no ductwork at all. Close to three homes in ten burn utility gas, frequently in a ducted furnace. We ask what heats your house before we book, so nobody pays for a visit that finds nothing to clean.
On the Delridge slope the city's landslide study found silt-clay soils up to 25 feet thick over hard clay, with groundwater typically high. The historical society's Delridge history lists periodic flooding among the valley's long-standing hazards, alongside ravines and creeks.
Ductwork often runs through a crawl space, and a crawl space on wet ground is a damp place. Joints that have separated pull that air into the return side, along with whatever dust and debris is down there. While we clean, we look along the reachable runs for open joints, crushed sections and insulation that has fallen away, and we note them in the report so they can be sealed. Clean ducts that still draw crawl-space air will not stay clean for long.
Every air duct cleaning we do in Delridge includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowWhen summer smoke drifts over the Sound, the regional Clean Air Agency's advice turns to filtration: run a HEPA unit, strap a MERV-13 or finer furnace filter to a box fan, pick one room to keep sealed, and shut the outside-air damper on an air conditioner. A good filter in the furnace helps only if the ducts downstream of it are not releasing their own load of dust every time the blower starts. We clean behind the filter so the filter can do its share.
We check that you have a ducted furnace or heat pump and note where the trunk lines and returns run.
We clamp the collector's hose into the largest duct, and from then on every register draws air in rather than pushing it out.
Starting at the branch most distant from the collector, we feed brushes and compressed-air whips through one run after another.
Registers go back on clean, the blower area and filter slot are cleaned, and photos show the inside of the ducts after.
Delridge's Census tabulation area, which also reaches south of Seattle, spans the whole postwar period: about one unit in five from 1940 to 1959, a median build year of 1981, and nearly a third built in 2000 or later. The heating survey for the same area lists a few hundred households still on fuel oil alongside the gas and electric majority.
Duct systems age with their houses. An older home may have had its oil furnace replaced by gas or a heat pump while keeping some or all of the original ducts, with joints and seams that have opened over the years. A newer one usually has tighter ductwork but may carry construction dust from the build or a later remodel. Either way, we photograph inside the runs so you can see what came out.

Delridge is a valley neighborhood between the two ridges of West Seattle, on Longfellow Creek, with homes of mixed ages, about a fifth of those in its ZIP code area from the 1940s and 1950s and nearly a third built since 2000. We work every part of it — Pigeon Point, Youngstown, Cottage Grove, Puget Ridge, Riverview included.
