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.

AfterFast, Reliable Air Duct Cleaning Across Sammamish
Air duct cleaning in Sammamish, WA typically costs $385 – $675 for a full residential system, and it’s a scheduled, multi-hour job, not a 30-minute knock-off. Our crews work across the Plateau, Pine Lake, and Klahanie every week, so we know the housing stock here: half 1980s-90s builds with aging flex duct, half 2005-2015 homes with sealed, insulated runs. That split means honest pricing and a real cleaning protocol matter more than a cheap coupon. Call (737) 727-2314 and you’ll get a written price before we touch a single vent.
Why Cardinal Air Duct Cleaning Is Sammamish’s Preferred Air Duct Cleaning Company
Sammamish homeowners tend to be detail-oriented, and they ask good questions. What’s actually in the ducts? Why does one quote say $89 and another says $500? Is this even necessary this year? We answer straight. Our technicians arrive in uniform, background-checked, with Rotobrush agitation tools and Nikro HEPA vacuums, and they hand you a written price before work starts. That number doesn’t move at the door.
Reviews from Sammamish customers consistently mention two things: the before-and-after photos and the fact that we didn’t push extra services. One recent job off Southeast 24th Street on the Plateau, a 1994 custom home, had original flex runs sagging behind a finished basement soffit. We source-removed about two cups of drywall dust and rodent debris per run, photographed each duct before and after, and flagged a blower motor issue without upselling. That’s the standard Omar Haddad set for this company.
Scheduling is coordinated from our Seattle office, but crews serve Sammamish locally, so you’re not waiting on a crew driving up from Tacoma to figure out where the Plateau is. The Relay Standard applies to every booking: a live arrival window you can track from your phone, photo proof of the work, and a digital invoice payable by link.
HVAC Duct Cleaning in Sammamish
HVAC Duct Cleaning in Sammamish means source-removing debris from the supply and return sides of a forced-air system, including the trunk lines, branch runs, registers, and the air handler cabinet. In Sammamish’s climate, where fall brings heavy leaf litter and pollen from the canopy-heavy lots, and winter means closed windows for months, the system recirculates the same air constantly. If the ducts haven’t been opened in a decade, that recirculated air is moving through accumulated dust, pet dander, and construction debris from the home’s original build. A full HVAC duct cleaning here runs $385 – $675 for a typical single-family home, depending on system size and the number of levels.
What the job actually involves
We start by inspecting the system with a video camera, especially on 1990s Plateau homes where flex duct often sags behind finished walls. Then we connect a Nikro HEPA vacuum to create negative pressure, meaning the loosened debris goes straight into the vacuum, not back into your living room. Rotobrush agitation tools work the inside of each run until the visible material is gone. We photograph the registers and mains before and after. It takes three to five hours for most Sammamish homes. Anyone promising to do it in under an hour is not source-removing anything.
When Sammamish homeowners should schedule it
After a major remodel is the most common trigger we see in Sammamish. Drywall dust gets pulled into the returns during construction and then redistributed for months afterward. The second most common: you moved into a home built before 2000 and no one can remember the ducts ever being opened. If you see fine dust accumulating on registers within days of wiping them, or if airflow feels weak in second-floor rooms, the ducts are the first thing we check. A Air Duct Cleaning visit with video inspection costs nothing extra and tells you what’s actually there before you commit to cleaning.
Vent Cleaning in Sammamish
Vent Cleaning in Sammamish is part of the full system, not a separate upsell. The vents, which are the visible grilles and boots at each register, collect dust, hair, and debris where air exits into the room. In Sammamish homes with pets, the lower vents in bedrooms and hallways are often coated with fine fur and dust. We remove the register covers, clean the boot with agitation tools under negative pressure, and wipe down the grilles before reinstallation. This is included in our flat per-system price, which for a standard Sammamish home runs $385 – $675.
Supply and return registers
Supply registers push conditioned air into rooms, and return registers pull air back to the air handler. Both get dirty, but returns usually collect more because they’re pulling unfiltered air from the living space. In Sammamish homes on the 1980s-90s Plateau side, return ducts are often oversized and short, so debris settles right at the return register and into the first few feet of the run. We clean both sides fully. One flat price per system, agreed before we start, regardless of how many registers you have.
Dryer vent note
Dryer vent cleaning is a separate service, and we’ll be direct about whether you need it. If your dryer takes longer than 45 minutes to dry a normal load and the vent exits through the roof or a long sidewall run, it’s likely backed up. Sammamish homes built in the 1990s often have dryer vents that exit through the roof, which collect lint faster than standard wall exits. We’ll tell you if we see a problem during the duct job, and you decide whether to have us clean it. We don’t package it into a duct quote or push it when it’s not needed.
Trusted Brands We Service in Sammamish
We work with equipment and filtration from Nikro, Honeywell, Aprilaire, and Abatement Technologies. What that means for a Sammamish homeowner: if your system has an Aprilaire media filter cabinet or a Honeywell electronic air cleaner, our technicians know how those integrate with the ductwork and won’t damage them during cleaning. We stock common filter sizes and replacement clips on the truck, so if we find a cracked filter frame or a worn Aprilaire gasket during the job, we can usually fix it the same visit rather than scheduling a return trip. That’s the practical value of a specialist truck over a pickup with a shop vac.
Common Air Duct Cleaning Problems We See in Sammamish Homes
- Sagging flex duct on 1990s builds. Homes off Southeast 24th Street, around Pine Lake, and in older Plateau neighborhoods often have original flex runs that were strapped too loosely and have settled over 20-30 years. We find pinched runs behind finished basement ceilings that trap debris and reduce airflow to upper floors.
- Drywall dust from remodels. Sammamish has a steady rate of kitchen and basement renovations, and the fine gypsum dust gets pulled through the returns during construction. It settles inside the ductwork, then blows out over the next six months. A post-remodel cleaning saves you from dusting every room twice a week.
- Pet dander and hair in homes with multiple animals. Larger Sammamish lots and the single-family housing stock mean many homes have two or more dogs or cats. That dander coats the inside of supply runs, especially on the return side where the filter is doing less than homeowners assume.
- Rooftop dryer vents on older builds. Homes built in the 1980s and early 90s often have dryer vents terminating through the roof, which fill with lint faster and are harder to access. We see these regularly when we’re already inside for a duct job and can clean them as a separate line item with clear pricing.
Pricing for Air Duct Cleaning in Sammamish, WA
A full residential air duct cleaning in Sammamish runs $385 – $675 for a single-family home. That’s one flat price per system, written down before we start. No per-vent math, no add-ons when we “find” extra runs during the job. The range exists because house sizes and system complexity vary: a 1,500-square-foot single-level home with eight registers is going to land near the lower end, while a 4,000-square-foot Plateau home on three levels with 20+ registers and long return runs lands near the top. You’ll know your exact number before the Rotobrush comes off the truck. Call (737) 727-2314 for a free estimate. We’ll ask a few questions about square footage, year built, and number of levels, and give you a written number. That number is what you’ll pay.

FAQs About Air Duct Cleaning in Sammamish
Most Sammamish homes need it every 5 to 7 years, with two exceptions: after any remodel that produced drywall dust, and within the first year after moving into a home built before 2000 where cleaning history is unknown. If you have pets and severe allergies, some homeowners choose every 3 to 4 years, but we’ll tell you honestly if a cleaning isn’t warranted. Call (737) 727-2314 and we’ll help you decide based on what we see, not a schedule.
Because per-vent pricing in Sammamish’s larger, multi-level homes creates an incentive to skip the long runs and count registers instead. A flat per-system price, agreed before we start, means the tech cleans the entire system thoroughly. $385 – $675 covers the whole house, regardless of register count. You get the written number before work begins, and it does not change.
Yes. Every Cardinal Air Duct Cleaning job includes photograph documentation of the ducts before and after we clean them, taken with an inspection camera inside the runs. You’ll see what we saw before work started and what it looked like when we finished. That’s the Relay Standard: photo proof, not just a verbal summary.
Yes and no. The core equipment is the same, Nikro HEPA vacuums and Rotobrush agitation tools, but the approach changes. Older Plateau homes with sagging flex runs need camera inspection first and more careful agitation to avoid damaging weakened duct. Newer 2005-2015 builds with sealed, insulated metal runs can be cleaned faster because we know the ductwork is rigid. The protocol adapts to the house, and we’ll tell you which one you have.
We don’t promise same-day service, and we’d be suspicious of anyone who does. A legitimate source-removal duct cleaning in Sammamish takes three to five hours with HEPA equipment. A same-day promise is usually a signal that the job will be a quick register wipe-down, not an actual cleaning. We schedule realistically, give you a live arrival window you can track, and do the full job.
