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.

Why Cardinal Air Duct Cleaning Is Renton’s Preferred Air Duct Cleaning Company
Renton homeowners tell us the same thing: they want a real price, a real arrival time, and proof the work happened. That’s exactly how we operate. Every booking comes with a live trackable arrival window through The Relay Standard, so you’re not stuck waiting in a four-hour block wondering if anyone will show. When our technician arrives in uniform, you’ll know their name before they ring the bell.
Our work is backed by the 365-Day Done Right Promise. If anything isn’t right within a full year, we come back and correct it at no charge. That applies to every job, not a select few. Omar Haddad leads the team, and he holds every technician to the same standard: written price first, before-and-after photo proof second, and no surprises in between. For renton homeowners who’ve been burned by vague estimates or bait-and-switch coupons, that’s the difference.
Commercial Air Duct Cleaning in Renton
Commercial Air Duct Cleaning in Renton covers office buildings, medical suites, restaurants, and light industrial spaces across the city, including properties near Southport and along Grady Way. Commercial systems run longer ducts, handle higher static pressure, and often serve mixed-use spaces where dust from one tenant space migrates into another. Our crews use Abatement Technologies containment units and Nikro HEPA vacuums to perform source removal without shutting down adjacent operations. A commercial duct cleaning in Renton generally runs $1,200 – $4,500 depending on square footage, number of rooftop units, and access constraints.
The process starts with a video inspection of the supply and return runs, then we build a containment strategy around each air handler. We clean the supply ducts, return ducts, coils, and blower cabinet in one pass. Before-and-after photos are standard, and property managers get a digital invoice payable by link.
Office and Retail Systems
Renton office buildings with VAV boxes and long flex runs need careful negative-pressure setup so loosened debris doesn’t drift into occupied workstations. We schedule commercial work around business hours where possible, including early mornings and weekends.
Restaurant and Kitchen Exhaust Adjacent Ducts
Restaurants in Renton’s downtown corridor deal with grease-laden air that coats supply and return ducts faster than typical office dust. We recommend a camera inspection every 18 – 24 months for food-service spaces, with full source removal as needed.
Air Duct Cleaning Services in Renton
Air Duct Cleaning Services in Renton cover the full scope: supply duct cleaning, return duct cleaning, full system cleaning, and video inspection. A standard single-family home in Renton runs $450 – $850 for a complete source removal, and we quote that as one flat price per system before we touch anything. No per-vent math, no add-on fees for the air handler or blower motor. You get the price in writing, and it doesn’t change when the van pulls up.
Our crews are trained on HEPA-rated negative-pressure extraction. That means the loosened debris goes straight into a sealed vacuum system, not back into your living room. We run Rotobrush agitation tools through supply and return ducts, clean the air handler cabinet, and finish with a camera pass so you see the result.
Supply and Return Duct Cleaning
Supply ducts push conditioned air into your rooms; return ducts pull air back to the handler. Both collect dust, and in Renton’s older homes the return side often carries pet hair and pollen straight into the blower. We clean both sides as one system, never one without the other.
Full System Cleaning with Video Inspection
Full system cleaning includes the ducts, the return plenum, the blower cabinet, and a video inspection before and after. This is the option we recommend for any Renton home that hasn’t had its ducts cleaned in five or more years, or where someone in the house has allergy symptoms that spike indoors.

Trusted Brands We Service in Renton
We service and maintain filtration systems from Aprilaire, Guardsman, and Honeywell, and we carry replacement media for most common Aprilaire filter cabinets used in Renton homes. If your system has an electronic air cleaner or a media filter housing that hasn’t been serviced in years, we’ll inspect it during the duct cleaning and let you know what needs attention. Our equipment fleet includes Rotobrush rotary brush systems, Nikro HEPA vacuums, and Abatement Technologies containment units. We stock common filter sizes and access panel hardware on the truck, so small fixes don’t require a second trip.
Common Air Duct Cleaning Problems We See in Renton Homes
- Cedar and alder pollen buildup in return ducts. Renton sits between Lake Washington and the Cascade foothills, and spring pollen loads here are heavy. Return ducts in Highlands and Renton Hill homes often carry visible yellow-green pollen into the blower cabinet, which then recirculates it through every room.
- Disconnected or crushed flex runs in older homes. Many 1960s and 1970s ramblers in Renton have original ductwork with joints that have loosened over decades. A camera inspection regularly shows gaps where conditioned air is escaping into crawlspaces or attics instead of reaching bedrooms.
- Pet hair and dander compacted in the return plenum. Homes with dogs and cats in Renton’s single-family neighborhoods often have return plenums packed with hair. This restricts airflow, shortens blower motor life, and pushes allergens through the supply side.
- Dryer lint bypassing a missing or torn duct seal. Dryer vents that run through Renton crawlspaces sometimes have torn foil or disconnected seams. That lint doesn’t just reduce dryer efficiency; it’s a fire hazard, and we inspect the full vent run during any duct cleaning.

FAQs About Air Duct Cleaning in Renton
Every 3 to 5 years for most Renton homes, though homes with pets, recent renovations, or residents with allergy symptoms may need it more often. Renton’s heavy spring pollen season, combined with cedar and alder pollen from the surrounding foothills, pushes some households to a 2-to-3-year cycle. If you haven’t had a video inspection in five years or more, that’s the place to start. Call (737) 727-2314 and we’ll talk through what your system actually needs, not what a coupon says it needs.
One flat price per system, agreed in writing before any work starts. We don’t charge per vent, and we don’t add surprise fees for the air handler or blower motor. Some Renton companies quote a low per-register price and then stack charges once they’re inside. We quote the whole job as one number. Call (737) 727-2314 for a free written estimate.
A video inspection first, then negative-pressure extraction with HEPA filtration, agitation of supply and return ducts with rotary brushes, cleaning of the blower cabinet and return plenum, and a final camera pass. You see before-and-after photos of your own ducts, not stock images. Call (737) 727-2314 and we’ll walk through what your system looks like and what the cleaning will cover.
Yes, and we recommend it. Dryer Vent Cleaning in Renton is important because vents in local homes often run through crawlspaces with turns that collect lint, and a clogged dryer vent is a fire hazard, not just an efficiency issue. We can add a dryer vent cleaning to any duct cleaning visit for a small additional charge. Call (737) 727-2314 and mention the dryer vent when you book.
Renton’s position between Lake Washington and the Cascades means outdoor pollen counts spike hard in spring and fall, and homes here close up tight during the wet months. What settles into your ducts stays in circulation through the heating season. Our crew spent a morning in the Highlands doing a full source removal on a 1970s ranch: a camera inspection showed the return ducts carrying cedar pollen and pet hair into the air handler, so we set up negative pressure with HEPA filtration and ran agitation tools through the supply and return ducts before sealing everything back up. The homeowner said the musty smell that had lingered in the hallway was gone by that evening.
If you’re ready for an honest Air Duct Cleaning in Renton, call (737) 727-2314. We’ll give you a written price before any work starts, a live trackable arrival window, and before-and-after photos of your own ducts when the job is done.
