Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.
Fast, Reliable Air Duct Cleaning Across Shoreline
Air duct cleaning and Dryer Vent Cleaning in Shoreline typically costs between $450 and $800 for a full system on a standard single-family home, and most jobs take four to six hours from setup to final photo.

We’re Cardinal Air Duct Cleaning, part of the Relay Home Co. family founded in 2005, and our Shoreline crews work on the systems this city actually has: 1950s and 60s ranch homes, daylight basements, converted oil-furnace ductwork, and long return trunks that most companies never touch.

Why Cardinal Air Duct Cleaning Is Shoreline’s Preferred Air Duct Cleaning Company
Shoreline homeowners tend to do their homework before booking home services. They ask about equipment, about pricing structure, about who exactly is walking into their house. That’s the right instinct, and we answer those questions directly. Our technicians are background-checked, uniformed, and you’ll know the tech’s name before they arrive. We run professional-grade equipment: Rotobrush rotary brush systems for agitation, Nikro HEPA-rated vacuums for negative-pressure extraction, and Abatement Technologies containment units so the debris we loosen goes into the vacuum, not back into your living room. The Relay Standard booking experience means a live trackable arrival window, before-and-after photo documentation of your own ducts, and a digital invoice you can pay from a link. Every job is backed by the 365-Day Done Right Promise: if the work isn’t right within a full year, we return and correct it at no charge.
Local reputation in Shoreline comes down to whether the crew actually reaches the dead-end trunks in a 1962 daylight-rambler off NE 165th or just hits the easy supply registers in the hallway. We judge the job by total duct layout, not by how many vents you can count from your couch. That distinction matters here more than almost anywhere in King County, and we’ll get into why below.
Vent Cleaning in Shoreline
Vent Cleaning in Shoreline means more than wiping register covers. The real work happens inside the duct runs behind those covers, and in a city where thousands of homes were built on slab foundations with original return trunks running under the floor, that work is not optional. When we clean vents in Shoreline, we’re pulling the registers, running agitation tools through the supply runs, and extracting the loosened debris with negative pressure. Negative-pressure extraction, by the way, means the vacuum is pulling air out of the ducts the entire time, so the fines and lint we dislodge go straight into a HEPA-filtered collection unit, not into your bedroom air. A supply-and-return vent cleaning on a typical Shoreline ranch home runs $250 to $400 when done as part of a full system clean.
Supply Vent Runs
Supply vents push conditioned air from your furnace out to the rooms. In Shoreline houses with original 1950s ducting, those supply runs were often sized for oil heat, not for the gas furnaces and heat pumps that replaced them. That means lower air velocity through longer runs, which means more dust settling in corners and elbows. We go register by register, but we price the system, not the register.
Return Vent Runs
Returns are where Shoreline duct systems show their age. A daylight basement return trunk running under a slab can collect decades of construction fines, pet hair, and lint. If the return side isn’t cleaned, the blower motor just re-circulates everything we loosened on the supply side. So we clean both sides, every time.
Air Duct Repair in Shoreline
Air Duct Repair in Shoreline usually starts with a video inspection. We send a camera through the ducts, find the actual problem, and show you the footage before we quote a repair. The most common repair calls we get in Shoreline are separated joints in crawlspace duct runs, crushed return trunks under slab floors, and disconnected boots where the duct meets the register. Loose duct tape from a 2005-era remodel job is another frequent find. Our crews carry sheet metal, mastic sealant, and replacement flex duct on the truck, so most repairs happen the same visit. Repair pricing in Shoreline follows the same rule as cleaning: a written price before any work starts, agreed up front, and a written guarantee on every repair with a free second visit if it fails. That guarantee is part of the 365-Day Done Right Promise, and it applies to every booking without exception.
Leaky Return Ducts
A leaky return pulls attic or crawlspace air into your system before it ever reaches the filter. That’s unfiltered air, and in Shoreline crawlspaces, that air carries whatever’s down there: dust, rodent droppings, dampness. If your blower motor is caked with fines or your Aprilaire filter collapses after a month, a return-side leak is the first thing we check.
Crushed or Separated Trunks
Shoreline’s 1960s-era slab homes sometimes have return trunks that were installed before the slab was poured. Those trunks can’t be replaced without major demolition, but they can often be repaired from the register side or through an existing access point. We’ll show you the camera footage and walk you through what’s fixable before we quote a dollar amount.
Trusted Brands We Service in Shoreline
We work on all major furnace and filtration brands you’ll find in Shoreline homes: Honeywell media cabinets, Aprilaire filter housings, Guardsman purification units, and just about every furnace brand tied to 1950s-to-1980s converted oil systems. Our trucks stock common replacement parts for Aprilaire and Honeywell filtration products, which means a clogged filter housing or a failed media cabinet gasket doesn’t need a second appointment. When you book with us, Air Duct Cleaning includes the filtration housing check as standard, not as an upsell.
Common Air Duct Cleaning Problems We See in Shoreline Homes
- Converted oil-furnace duct layouts. Shoreline’s housing boom happened in the 1950s and 60s, when oil heat was standard. When those systems converted to gas or electric, the ductwork stayed. Those original runs are often oversized for the new equipment, so air moves slower and dust settles faster.
- Daylight basement return trunks under slab. We mentioned this earlier, and it’s the single most common issue we see. These runs can’t be swapped out easily, so they load up with decades of debris. A camera inspection tells you exactly what’s in there before we clean it.
- Post-remodel drywall fines. A 2019 kitchen remodel or a 2022 basement finish produces fine drywall dust that gets pulled into the return side and lingers. In Shoreline, where a lot of homes have been remodeled in place rather than rebuilt, this is a recurring pattern.
- Collapsed filter media. Homes with Aprilaire or Honeywell media cabinets in crawlspace locations see more filter failures. High static pressure from dirty coils and loaded ducts collapses the filter media, which then lets unfiltered air bypass the system. Cleaning the ducts and blower drops that static pressure.
We were at a daylight-rambler off NE 165th in the Ridgecrest neighborhood last month, a 1962 house with original return trunks running under the main-floor slab. The blower motor had been caked with fines since a 2019 remodel, and the homeowner’s Aprilaire filter was collapsing every few weeks. After a camera inspection showed a lint pathway back to the air handler, we set up negative pressure with HEPA filtration and ran agitation tools through the supply and return ducts. The after-photos of the same trunk showed bare galvanized steel, and the homeowner’s static pressure dropped enough that their filter stopped collapsing. That’s the standard we hold every Shoreline job to.
Pricing for Air Duct Cleaning in Shoreline, WA
A full air duct cleaning for a standard Shoreline single-family home runs $450 to $800, depending on the number of systems, the total duct layout, and whether we’re also cleaning the blower motor and air handler. A condo or smaller daylight basement unit typically lands between $350 and $500. Commercial duct cleaning in Shoreline starts around $800 and scales with square footage and duct complexity. What affects the number: how many systems (a furnace plus a separate heat pump adds time), whether the return trunks run under slab, and whether the blower motor needs extraction work. We quote one flat price per system before any work starts. No per-vent pricing. No bait-and-switch at the truck. Call (737) 727-2314 for a free estimate with a written number.

FAQs About Air Duct Cleaning in Shoreline
Most Shoreline homes need air duct cleaning every three to five years. Homes with pets, recent remodels, or converted oil-furnace ductwork in the 1950s-to-60s age range may need it more often. If you’ve never had it done and your house was built before 1980, it’s worth a camera inspection to see what’s actually in the ducts before deciding. Call (737) 727-2314 and we’ll walk you through what to look for.
We charge one flat price per system, agreed before any work starts. Per-vent pricing is how duct cleaning companies hide the real cost, especially on Shoreline homes where the work is in long return trunks and air handlers, not in the number of hallway registers. The number we quote on the phone is the number on your invoice. A written price is handed to you before a single duct is touched, and it does not change at the door.
You get before-and-after photos of your own ducts, taken with the same camera we use for inspection. We photograph the return trunks, the supply runs, the blower motor, and the air handler before we start, then we photograph the same spots after extraction. The photos are delivered digitally with your invoice, so you can see the bare galvanized steel where there used to be a lint pathway. If a section wasn’t reached, the photos will show that too, and that triggers the 365-Day Done Right Promise.
Yes. The blower motor and air handler are where the fines settle in Shoreline homes with converted oil-furnace systems, especially after a remodel. We extract the blower motor, clean the housing, and check static pressure before and after. If your Aprilaire or Honeywell filter has been collapsing, cleaning the blower and ducts usually fixes the pressure problem. A blower motor service is included in our full system cleaning, not billed as a separate add-on.
We schedule by appointment, and our Shoreline crews are typically able to book within a few days depending on current volume. We don’t promise same-day service, because a proper duct cleaning on a Shoreline home takes four to six hours and we don’t rush the camera inspection or the extraction. Call (737) 727-2314 and a live person will answer 24/7, give you a written quote, and get you on the schedule.
