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 Walnut Creek
Air duct cleaning in Walnut Creek typically runs $450-$850 for a whole-home system, with most jobs completed in a single visit. Our crews work from the San Francisco Bay Area office and serve Walnut Creek homes directly, carrying Rotobrush and Nikro equipment sized for the 1960s ranch-style tract homes and multi-story condo complexes that define this city’s housing stock. Call (323) 918-4345 for a written estimate before any work starts.
We’ve been in enough Walnut Creek attics to know what we’re walking into. Original flex-duct from the Johnson, Larkey, and Rossmoor developments has had fifty-plus years to disconnect, crush, or load up with dust. The Diablo Valley heat pushes HVAC systems harder than coastal cities, and wildfire seasons pull fine particulates straight into ductwork. That’s why our Air Duct Cleaning team doesn’t just vacuum registers. We inspect, we find the real problems, and we tell you exactly what it’ll cost to fix them before we touch anything.
Why Morton’s Air Duct Cleaning Is Walnut Creek’s Preferred Air Duct Cleaning Company
Walnut Creek homeowners call us back because we treat the house like it’s our own. Shoe covers and drop cloths go down before the equipment comes in. If there’s a dog on the floor or a toddler napping down the hall, we use quieter tools and work around the schedule. Every technician is background-checked and uniformed, and every job carries our 365-Day Done Right Promise - if it’s not right, we make it right, stamped on the paperwork, not just offered if you complain.
We’ve built our reputation in neighborhoods from Larkey Valley to the Rossmoor gates by showing up when we say we will and leaving a photo of the clean-up behind. No surprise invoices. No per-vent upsells. One flat price per system, agreed in writing before we start. That’s the Cedarwell Care Promise, and it’s how we’ve operated since 2005.
When you call (323) 918-4345, a live person answers. Not a chatbot, not a callback queue. We coordinate dispatch from our Bay Area office, but the crew that arrives knows Walnut Creek’s specific building types and access requirements, especially the HOA-coordinated jobs that catch less experienced companies off guard.
Air Duct Inspection in Walnut Creek
Air Duct Inspection in Walnut Creek starts with a camera run through your supply and return lines, because surface cleaning won’t fix what you can’t see. In the 1960s ranch homes off Ygnacio Valley Road and the multi-story Rossmoor buildings, we regularly find disconnected flex-duct dumping conditioned air into attics, crushed runs flattened by decades of foot traffic in shared utility spaces, and smoke residue from the 2018 and 2020 wildfire seasons still clinging to duct walls. A typical inspection runs $150-$250, and we’ll show you the video before quoting any cleaning or sealing work.
What the Camera Reveals
Our Nikro video inspection systems push through sheet-metal and flex-duct alike, recording every joint, seam, and accumulation point. In Walnut Creek’s unconditioned attics, we often spot original duct tape that’s turned to dust, leaving gaps that pull attic air straight into your living space. You’ll see it on the screen. We’ll explain what it means. Then we’ll write down what it costs to fix.
When to Schedule First
If your home was built between 1960 and 1980 and has never had a duct inspection, start here before paying for any cleaning. We’ve seen $800 cleaning quotes turn into $400 jobs once the camera shows the real problem is a single disconnected run. Or the opposite - a cheap cleaning that missed $1,200 worth of sealing work the system actually needed. The inspection removes the guesswork.
Residential Air Duct Cleaning in Walnut Creek
Residential Air Duct Cleaning in Walnut Creek means source removal with professional agitation and negative-pressure HEPA containment, not a shop vacuum and a prayer. For a typical 1,500-2,500 square foot home in the Larkey or Arbolay neighborhoods, whole-system cleaning runs $450-$650. Rossmoor condos and co-ops, with their extended duct runs and HOA-coordinated access, often fall in the $550-$850 range depending on system complexity. We use Rotobrush contact cleaning for flex-duct and Nikro high-velocity tools for sheet-metal trunk lines, with Abatement Technologies HEPA filtration protecting your home while we work.
Protecting Your Space
We lay drop cloths from the front door to the attic access and back. Shoe covers stay on until we leave. Pet areas get a wide berth, and if you’ve got a nap schedule, we’ll schedule around it. Our technicians work to the Cedarwell C.A.R.E. values - that’s a system, not a slogan - and the photo we take of your clean floors and registers before we leave is proof we followed it.
The Sealing Work That Matters
Cleaning removes what’s loose. Sealing fixes what’s broken. In Walnut Creek’s original 1960s-70s systems, we find disconnected or crushed runs in roughly one of every three homes we inspect. We’ll reconnect and seal them with proper materials, quote the work separately, and never bundle it into a surprise. The written price covers exactly what we agreed to. Nothing more.
Trusted Brands We Service in Walnut Creek
We carry professional-grade equipment from Nikro, Honeywell, and Aprilaire on every Walnut Creek job, not rental-shop gear that struggles with fifty-year-old accumulation. Our Rotobrush systems handle the original flex-duct common in Diablo Valley ranch homes without tearing fragile material, while Nikro high-velocity whips break loose packed dust in sheet-metal returns. For filtration upgrades after cleaning, we stock Honeywell and Aprilaire MERV-rated media that actually catches the fine particulates Walnut Creek’s inland valley position concentrates during wildfire season. Parts are on the truck. Turnaround is same-visit. You don’t wait two weeks for a filter order while your newly cleaned system pulls dirty air again.
Common Air Duct Cleaning Problems We See in Walnut Creek Homes
- Disconnected flex-duct in unconditioned attics. Original 1960s-70s flex-duct in Walnut Creek’s ranch homes has often separated at joints, dumping heated or cooled air straight into insulation. Homeowners notice weak airflow at registers and higher utility bills, but the real damage is hidden above the drywall.
- Wildfire smoke residue recirculating year-round. Walnut Creek’s position in the Diablo Valley traps fine particulates from Northern California wildfires, and without source removal and upgraded filtration, that 2018 or 2020 residue recirculates every time the HVAC cycles. Surface cleaning doesn’t touch it.
- Crushed supply and return runs in Rossmoor buildings. Multi-story condo complexes with shared utility chases see decades of maintenance traffic flatten ductwork. We find runs compressed to half their original diameter, choking airflow and forcing the system to overwork in summer’s 100°F heat.
- HOA access delays compounding dust loads. Rossmoor’s roughly 6,700 units require building management coordination for duct access, and crews unfamiliar with this workflow show up unprepared, get turned away, and let another season pass. We handle the coordination so the job actually happens.

FAQs About Air Duct Cleaning in Walnut Creek
Rossmoor’s 6,700-plus units were built primarily in the 1960s and 1970s with original flex-duct that has never been cleaned in many cases, plus shared utility chases where maintenance traffic has crushed runs flat. Standard cleaning removes loose dust but doesn’t reconnect disconnected lines or seal leaks. We quote cleaning and any needed sealing separately, with video proof of what we found. Call (323) 918-4345 for a Rossmoor-specific estimate.
Camera inspections in Walnut Creek regularly reveal disconnected flex-duct joints, crushed runs in attics, wildfire smoke residue coating duct walls, and failed original duct tape at seams. In a 1968 ranch-style home off Rossmoor Parkway, our tech pulled a camera inspection through the original flex-duct in the unconditioned attic and found three disconnected runs dumping conditioned air straight into the insulation. We set up negative pressure with HEPA filtration at the air handler, used agitation tools to break loose decades of dust and wildfire smoke residue, then reconnected and sealed the crushed supply and return ducts before the homeowner scheduled their first cleaning since construction.
Walnut Creek sits in the Diablo Valley, fully inland and cut off from the coastal fog belt, regularly reaching 95-105°F in summer. HVAC systems here run far harder and longer than in Oakland or Berkeley, accelerating dust circulation and putting more stress on already-aging duct joints. Clean ducts move air more efficiently, but sealed ducts matter even more - every disconnected run forces the system to work longer to reach thermostat setpoints. We inspect for both.
Rossmoor jobs require coordinating access through building management rather than a single homeowner, a workflow quirk unique to this property type in Walnut Creek. We handle that coordination directly, scheduling through the appropriate channels so our crew arrives with proper clearance. Jobs that skip this step get turned away at the door, letting dust loads compound for another season. We’ve done enough Rossmoor buildings to know the process, and we build that time into our scheduling.
Yes, our cleaning protocols align with NADCA source-removal standards - negative pressure containment, mechanical agitation, and HEPA filtration on every job. Our equipment from Nikro, Rotobrush, and Abatement Technologies is sized for the specific duct materials found in Walnut Creek’s 1960s-70s housing stock, and we document the work with before-and-after video when possible. The 365-Day Done Right Promise backs every job, and the written price you receive before we start reflects exactly what those standards require for your system.
