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.

We’re Morton’s Air Duct Cleaning, and we’ve been part of the Cedarwell family since 2005. Our technicians know Clayton’s housing stock, the Diablo wind patterns that surge through from Mount Diablo, and what it takes to clean ductwork in the ranch-style and split-level tract homes that dominate this community. When you call (323) 918-4345, a live person answers, and we’ll give you a written price before any work starts. Every visit includes shoe covers, drop cloths, and a photo of the clean-up before we leave.
Why Morton’s Air Duct Cleaning Is Clayton’s Preferred Air Duct Cleaning Company
Clayton homeowners call us back because we treat their houses like we treat our own. Our Air Duct Cleaning team arrives in uniform, background-checked, and trained to the Cedarwell C.A.R.E. values. We notice the dog bed in the corner and the baby monitor on the counter. We use quieter tools during nap hours, and we lay drop cloths before we touch a floor.
Our reputation here is built on one thing: doing what we said we’d do, at the price we said we’d do it for. The 365-Day Done Right Promise isn’t a slogan we mention when asked. It’s stamped on every job. If something isn’t right, we make it right. Full stop. That matters in a small community like Clayton, where neighbors talk on Nextdoor and at the farmers market on Main Street.
We coordinate scheduling from our Bay Area office, but our crews are in Clayton regularly, serving homes from the Oakhurst Country Club area to the hillside streets off Marsh Creek Road. We know the difference between a Concord commute and a Clayton hillside, and we plan our equipment loads accordingly.
Vent Cleaning in Clayton
Vent cleaning in Clayton addresses the supply and return registers where conditioned air enters your rooms and where stale air gets drawn back to the air handler. In Clayton’s climate, these vents collect more than ordinary household dust. Diablo wind events push wildland particulate through your system, and that material settles on vent louvers and in the short duct runs behind them. A typical vent cleaning in Clayton runs $120-$220 as part of a larger system clean, or $180-$320 as a standalone service focused on registers and immediate duct branches.
Supply Vent Deep Cleaning
Supply vents push cooled or heated air into your living spaces. In Clayton’s triple-digit summer months, these run constantly, and any debris on the louver surfaces gets baked and recirculated. We remove each register, clean the visible surfaces, and use Rotobrush agitation tools to scrub the first several feet of duct behind it where dust cakes thickest.
Return Vent and Boot Cleaning
Return vents are the intake side, and in Clayton they work hardest during Diablo wind season. We clean the grille, the boot, and the immediate duct connection, checking for filter bypass damage where unfiltered air has slipped past a poorly fitted or overloaded filter. This is where wildland ash often shows up first.
Air Duct Repair in Clayton
Air Duct Repair in Clayton focuses on the aging flex duct and sheet-metal runs in homes built during the 1960s through 1980s, when most of Clayton’s residential development occurred. Original ductwork in these homes is now 40-50 years old. The flex duct liners crack, the fiberglass insulation degrades, and sheet-metal seams separate under decades of thermal expansion. A typical air duct repair in Clayton runs $280-$550 for localized fixes like resealing a plenum or replacing a damaged flex run, while more extensive sectional replacement can reach $800-$1,400 depending on attic or crawl space accessibility.
Flex Duct Replacement
The original flex runs in Clayton’s ranch and split-level homes were often installed with minimal support, causing sagging and compression that restricts airflow. We replace damaged sections with properly supported, insulated flex duct rated for the temperature swings these attics see.
Sheet-Metal Seam Sealing
Older sheet-metal ductwork in Clayton homes develops leaks at longitudinal seams and joint connections. We use mastic sealant and mechanical reinforcement, not tape that will fail in the heat, to restore system pressure and stop conditioned air from bleeding into your attic.
Trusted Brands We Service in Clayton
Our trucks carry professional-grade equipment from Nikro, Honeywell, and Abatement Technologies, not rental-shop vacuums with a duct attachment. For Clayton homeowners, this means we can source replacement components and filtration upgrades without waiting on regional distribution. We stock Honeywell media filters and Aprilaire cabinet systems that fit the air handlers common in Clayton’s 1970s and 1980s tract homes. When a repair calls for a specific part, our relationship with these manufacturers means faster turnaround and fewer return trips. Our technicians train directly on the equipment they use, so a Rotobrush brush-and-vac system or a Nikro negative air machine isn’t unfamiliar gear they pulled from the warehouse that morning.
Common Air Duct Cleaning Problems We See in Clayton Homes
- Diablo wind ash loading in hillside homes. Properties backing onto Mount Diablo State Park open space see HVAC filters clog within days of a strong wind event. The ash and fine particulate that gets past the filter settles in return duct runs, creating a reservoir that continues to recirculate even after the wind stops.
- Original flex duct degradation in 1960s-1980s tract homes. Clayton’s ranch and split-level housing stock uses flex duct that has exceeded its design life. The inner liner becomes brittle, the insulation compresses, and the vapor barrier tears, allowing attic dust to contaminate the airstream.
- Filter bypass from improper sizing or installation. Homeowners upgrade to high-MERV filters without checking compatibility, causing the filter to bow or gap. Unfiltered air pulls directly into the return plenum, accelerating buildup in the air handler and supply ducts.
- Moisture and biofilm in low-velocity duct sections. Clayton’s inland heat creates temperature differentials in duct runs that pass through unconditioned spaces. Slow airflow zones develop condensation, supporting microbial growth that a fogging treatment will coat but not remove.
Pricing for Air Duct Cleaning in Clayton, CA
Most complete residential air duct cleaning jobs in Clayton fall between $350 and $650 for a single HVAC system. This covers the full supply and return duct network, register cleaning, air handler cabinet, and a post-cleaning photo of the work. Commercial systems or homes with multiple zones typically run $550-$950. What moves the needle: system size, accessibility of duct runs in attic or crawl space, and the degree of buildup we find during our initial camera inspection.
We do not quote per-vent pricing. That structure invites bait-and-switch tactics, and we’ve heard too many stories from Clayton homeowners who accepted a low per-vent rate and watched the final invoice triple with “necessary” add-ons. At Morton’s, you get one flat price per system, agreed in writing before we start. No surprises. Call (323) 918-4345 for a free estimate.

FAQs About Air Duct Cleaning in Clayton
It’s a duct problem that shows up at the filter first. The filter is doing its job by catching what it can, but the fine ash and grass seed getting past it is settling in your return ducts and air handler. We treat these Clayton hillside homes as wildland-particulate loads, not filter failures. Call (323) 918-4345 and we’ll run a camera inspection to show you what’s actually inside the ductwork.
You need it if your system shows the signs we see regularly in Clayton: filters clogging faster than manufacturer intervals, visible dust on supply registers, or reduced airflow from returns. The Diablo wind loading here is real and measurable, not a sales fiction. We don’t sell duct cleaning to homes that don’t need it; we show you the camera footage and let you decide. Estimates are free.
A real cleaning removes the source. We use negative pressure HEPA containment and mechanical agitation to pull ash, dust, and biofilm out of your ducts. Fogging coats surfaces with a chemical layer but leaves the debris in place. In Clayton’s climate, where wildland particulate and moisture-nourished growth are the actual problems, fogging is a cosmetic treatment, not a solution. We don’t offer it as a substitute for source removal.
Expect aging flex duct with brittle liners, compressed insulation, and possible rodent damage in attic runs. The sheet-metal plenum and trunk lines may have separated seams. We camera-inspect every 1970s Clayton home before quoting cleaning or repair, because the condition of the ductwork determines whether cleaning alone is appropriate or if repair sections are needed first. The inspection itself is included in our estimate visit.
Clayton homes, especially on the eastern edges near Mount Diablo, typically need cleaning every 2-3 years versus the 3-5 year interval common in Concord or Walnut Creek. The Diablo wind events and wildland particulate loading here are genuinely more intensive. Homes with original 1960s-1980s ductwork may need more frequent inspection even if full cleaning isn’t required every cycle. Call (323) 918-4345 and we’ll recommend an interval based on your specific address and system age.
