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 Kent’s Preferred Air Duct Cleaning Company
Kent homeowners deal with a specific problem: houses here split between 1960s-era ranches on the East Hill and much newer construction near Kent Station and the Valley floor. That means one home might have original galvanized duct trunks running through the crawlspace, while another has flex runs snaked through tight attic spaces. Our Air Duct Cleaning team carries camera equipment to see exactly what’s inside before we touch anything.
Every booking runs through The Relay Standard, so you get a trackable arrival window, a technician’s name before they show up, and photo proof of the work when it’s finished. Omar Haddad leads our Kent operation, and every tech is background-checked and uniformed. The 365-Day Done Right Promise covers every job for a full year. If something isn’t right, we return and fix it at no charge. That’s a long satisfaction window in this trade, and we put it in writing on every invoice.
Air Duct Repair in Kent
Air Duct Repair in Kent usually means fixing sagging flex runs, resealing leaking joints, or replacing a section of crushed trunk line. On the East Hill specifically, a lot of 1950s and 60s homes had flex runs added during remodels, and those cheap sections often tear or collapse. You’ll notice it as weak airflow to certain rooms, dust blowing out of registers, or a furnace that runs longer than it should. Repair pricing in Kent runs $150 to $500 per section, depending on access and whether we’re replacing flex or patching galvanized metal.
Flex Run Replacement
Flex runs sag, tear, and collect dust faster than rigid metal. We replace damaged sections with properly sized and insulated flex, then rebalance the airflow to that room. Most flex replacements in Kent take under two hours and include a camera check before and after.
Duct Sealing and Leak Correction
Leaky duct joints bleed conditioned air into your crawlspace or attic. We seal seams with mastic, not tape, because mastic doesn’t dry out and peel. The before-and-after photos show the sealed joints, so you know exactly what was fixed.
Ductwork Cleaning in Kent
Ductwork Cleaning in Kent homes means removing the dust, pet hair, and construction debris that accumulates inside supply and return lines. Most Kent homes need this every 5 to 7 years, though houses with pets, smokers, or recent remodeling can need it sooner. Full ductwork cleaning in Kent runs $450 to $750 for a typical 3-bedroom home. We clean the full system: supply ducts, return ducts, the trunk line, and the air handler cabinet.
Source Removal with Negative Pressure
We hook a Nikro HEPA-filtered vacuum to your duct system to create negative pressure. That means every particle we loosen with Rotobrush agitation tools gets pulled into the vacuum, not blown back into your living room. It’s the difference between actually removing debris and just redistributing it.
Before-and-After Photo Verification
You get photos of your duct interiors before we start and after we finish. You’ll see what the original galvanized trunk looked like and what it looks like clean. No other duct cleaner serving Kent shows you the inside of your own ducts on a phone-ready invoice.
Trusted Brands We Service in Kent
We work on whatever your house already has: original galvanized trunks, fiberglass duct board, flex runs, and modern insulated systems. When replacement parts are needed, we stock Guardsman and Aprilaire filtration products locally, and our Abatement Technologies containment units keep the work area clean during larger repairs. Faster turnaround for Kent customers usually means one visit, because the parts are already in the van. No week-long waits for a flex section or a filter rack.
Common Air Duct Cleaning Problems We See in Kent Homes
- Sagging flex runs from remodels. A 1960s ranch off James Street gets a garage conversion, someone adds a cheap flex run, and five years later it’s pinched and leaking. Dust blows out of registers every time the blower kicks on.
- Skipped air handlers. Crews that only brush supply and return ducts never touch the blower motor or evaporator coil. That’s the biggest dust reservoir in the system, and ignoring it means the dust comes back within months.
- Fog-only cleaning. Some outfits fog the system with a deodorizer and call it clean. Fogging doesn’t remove debris. When the air kicks on, the dust redistributes through the registers, and the homeowner paid for nothing.
- Per-vent pricing that climbs. A low price per register quoted over the phone turns into a much higher invoice once the tech sees the actual duct footage and the sagging runs typical of East Hill remodels. The price you get from us is one flat price per system, agreed before work starts.

FAQs About Air Duct Cleaning in Kent
Every 5 to 7 years for a typical Kent home. Homes with pets, smokers, recent remodeling, or a long heating season may need it every 3 to 5 years. If you’ve never had it done and your house is 20+ years old, it’s probably time.
One flat price per system, agreed in writing before any work starts. We do not charge per vent. The written price you approve is the price you pay, even if the job takes longer than we estimated.
We connect a HEPA-filtered Nikro vacuum to create negative pressure, then run Rotobrush agitation tools through every supply and return duct, the trunk line, and the air handler. Debris goes into the vacuum, not your home. You get before-and-after photos of your duct interiors on a digital invoice.
Yes. If our camera inspection finds sagging flex, crushed metal, or leaking joints, we quote the repair separately in writing. You approve it, and we fix it during the same visit. Same-day repair saves you a second appointment and another service call.
Ask whether they use negative pressure with HEPA filtration and whether they’ll show you before-and-after photos of the duct interiors. Fogging alone doesn’t remove debris, it just masks it. We do source removal, and we document it with camera photos you can see on your phone. Call (737) 727-2314 for a free quote.
