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 Bothell
Air duct cleaning in Bothell typically costs $425 – $780 for a full single-system home, and the honest answer is that most houses here need it every 3 – 5 years, not annually. We’re Cardinal Air Duct Cleaning, part of the Relay Home Co. family founded in 2005, and we serve Bothell with a straight answer on price before any work begins. If your registers in Canyon Park or North Creek are blowing weak or the house smells stale every time the furnace kicks on, call (737) 727-2314 and we’ll walk you through what’s actually worth doing.
Bothell’s split between King and Snohomish counties doesn’t change how ducts get dirty, but it does change who’s driving out to you. We schedule Bothell jobs from our Seattle metro office and our crews work the Bothell-Woodinville corridor regularly, so we know the housing stock and the traffic patterns. A live person answers when you call, and every appointment comes with a trackable arrival window through The Relay Standard. You’ll know the technician’s name before they knock.
Why Cardinal Air Duct Cleaning Is Bothell’s Preferred Air Duct Cleaning Company
Bothell homeowners call us because we do not play the per-vent pricing game. A quote of “$99 for up to 10 vents” sounds fine on the phone, but a 1990s two-story in the Canyon Park area often has 14 – 18 registers. The invoice balloons the moment the tech starts counting. We give you one written price per system before anything is touched, and that number does not move at the door. It is a flat rate for the whole duct system, agreed up front.
Every booking runs on The Relay Standard. You get a live trackable arrival time, before-and-after photos of your own ducts, and a digital invoice you can pay from your phone. No four-hour windows, no guessing who’s on the way. Omar Haddad leads our team, and every technician is background-checked and arrives in uniform with professional equipment, Rotobrush rotary brush systems for agitation and Nikro HEPA-rated vacuums for negative-pressure extraction.
The 365-Day Done Right Promise covers every job we do in Bothell, no exceptions. If the work isn’t right within a full year, we come back and make it right at no charge. That is the longest-standing satisfaction window in the trade, and it applies to every booking, not just the ones where someone asks about it.
Air Duct Repair in Bothell
Air Duct Repair in Bothell typically runs $180 – $420 depending on the failure, and it is one of the most common things we do in homes between Thrasher’s Corner and the Sammamish River. Much of Bothell’s housing stock was built in the 1990s and 2000s, which means flex duct runs that are now 20 – 30 years old and starting to fail at the connections. A collapsed flex section or a disconnected boot behind a register can cut airflow to a room by more than half, and no amount of dust removal fixes that.
Re-Sealing and Reconnecting Aging Flex Duct
When we find a disconnected or collapsed flex run during a cleaning, we repair it on the spot. That means re-securing the inner liner to the collar, pulling the insulation jacket back over, and sealing the connection properly. In Bothell homes built during the 1990s and 2000s, these connections were often taped rather than mastic-sealed at installation, and that tape fails after a couple of decades. We also replace pinched sections where flex was routed too tightly behind an air handler or through a joist bay.
Camera Inspection for Hidden Damage
We run a camera down the main trunk line on most jobs in Bothell, especially in two-story homes where the ductwork runs through spaces nobody has seen since construction. A camera inspection catches collapsed flex, rodent damage, and buildup inside the plenum that a visual check at the register would miss. The inspection is included with any full-system cleaning, and you get the footage as part of your before-and-after documentation.
Ductwork Cleaning in Bothell
Ductwork Cleaning in Bothell for a standard single-system home runs $425 – $780, and the price depends on the home’s square footage, the number of returns, and whether the system has ever been cleaned before. In Bothell, that matters because so many homes here share a single return air pathway per floor, which means the return side pulls from multiple rooms and collects dust from the entire house. We clean the supply runs, the return runs, the main trunk, and the air handler cabinet as one system, not as a count of vents.
Full System Cleaning
Full System Cleaning means we clean the entire ductwork pathway from the return grilles to the supply registers, including the main trunk lines and the air handler cabinet. We do not skip the cabinet. In Bothell’s older flex duct systems, the blower motor and housing collect a layer of dust that reduces efficiency and shortens the motor’s life. We clean it, photograph it, and show you the before and after.
Video Inspection
Video Inspection is standard on every full-system cleaning in Bothell. We run a camera through the trunk line and main branches, looking for collapsed flex, disconnected boots, moisture stains, and anything else that affects airflow. The footage is yours, and if we find a problem, you get a written photo-backed explanation of what it is and what it costs to fix. There is no pressure to repair on the spot; you decide, and the written quote sits in your inbox.
Trusted Brands We Service in Bothell
Bothell homes run on a mix of builder-grade equipment from the 1990s and newer high-efficiency systems, and we service both ends of that spectrum. We clean and maintain systems from Honeywell, Aprilaire, and Guardsman filtration lines, and our equipment fleet includes Rotobrush rotary brush systems, Nikro HEPA-rated vacuums, and Abatement Technologies containment units for jobs that need separation and air scrubbing. If your Bothell system has an Aprilaire filter housing or a Guardsman media cabinet, our techs know the housing and the replacement schedule. We keep common filtration parts on the truck so a cleaning can include a filter replacement right then.
Common Air Duct Cleaning Problems We See in Bothell Homes
- Collapsed or pinched flex duct in 1990s and 2000s homes. Bothell’s housing boom in that era leaned on flex duct, which sags and kinks as it ages. A pinched run behind the air handler is one of the most common reasons a second-floor bedroom in Canyon Park barely gets airflow.
- Heavy return-side buildup from pets and carpet. The return grille in many Bothell houses pulls air from high-traffic areas, and with the wet winters and dry summers, that grille becomes a grey mat of hair and dust. Cleaning the return path and the blower cabinet together is the only way to actually fix it.
- Builder-grade air handler cabinets caked with dust. Homes built around the 1990s often have air handlers that were never sealed well at installation. Dust bypasses the filter, lands on the blower motor, and bakes on. That buildup cuts airflow and pushes the system harder than it should run.
- Disconnected boots at the register. We regularly find supply boots that have pulled loose from the drywall or the floor register in Bothell homes. The duct is pushing conditioned air into the joist cavity or the attic instead of the room, and the homeowner’s utility bill shows it. We re-secure and seal those connections during a cleaning.

We were called to a two-story in the Canyon Park area where the upstairs registers were barely moving air and the return grille was caked with a dark grey mat of dust and pet hair. After setting up negative pressure with our Rotobrush and HEPA filtration, we used agitation tools on the supply and return ducts, then ran a camera inspection down the main trunk and found a collapsed section of flex duct pinched behind the air handler. We replaced and re-sealed that run, cleaned the blower motor and housing, and the homeowner sent us before-and-after photos showing the airflow difference at the same registers.

FAQs About Air Duct Cleaning in Bothell
Most Bothell homes need air duct cleaning every 3 – 5 years, not every year. Homes with multiple pets, recent renovation work, or smokers may need it sooner, around the 2 – 3 year mark. If your system was built in the 1990s and has never been cleaned, schedule once and then set a reminder for several years out, not annually. If you’re unsure whether your ducts actually need it, call (737) 727-2314 and we’ll ask the right questions before you spend a dollar.
We charge one flat price per system. The quote is written down and handed to you before any work starts, and it does not change based on how many registers we count. Per-vent pricing quotes low on the phone and balloons the moment a technician starts walking your Bothell two-story. We think that is a bad way to do business, so we don’t do it. Call (737) 727-2314 for a flat per-system quote.
It involves connecting a HEPA-rated vacuum to the system to create negative pressure, then agitating the inside of the supply and return ducts with a rotary brush to loosen debris, which is pulled into the vacuum rather than released into the living space. We also clean the air handler cabinet, the blower motor, and the return plenum. In Bothell homes with flex duct, we inspect and re-seal connections as part of the job. You get before-and-after photos of your own ducts when we’re done.
Yes, and we usually do. If the camera inspection finds a collapsed section of flex or a boot that has pulled loose, we fix it during the same visit. The repair is quoted separately and in writing before we touch it, so you know the exact dollar figure before any additional work starts. Bothell homes from the 1990s and 2000s see this often, and we carry the materials to re-seal and reconnect on the truck.
No, and we won’t pretend otherwise. Duct cleaning is a scheduled job that takes several hours to do properly, and a crew that promises same-day service is cutting corners somewhere. We book Bothell appointments in a live trackable arrival window through The Relay Standard, and a real person answers the phone at (737) 727-2314 to get you scheduled. You’ll know the technician’s name and arrival time before they get to your door.
