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 Danville
Air duct cleaning in Danville, CA typically costs $450-$850 for a full residential system and is scheduled by appointment with a written price confirmed before any work begins. Most Danville homes, especially the large executive properties built in the 1980s and 1990s, contain multi-zone HVAC systems that require per-system pricing and documented cleaning of each unit separately. Call (323) 918-4345 for a free estimate with no obligation.
We’ve been driving out to Danville since 2005, and our dispatch team coordinates scheduling from our San Francisco Bay Area office so crews arrive prepared for the specific layout of your home. Whether you’re off Diablo Road near the village, up in the Blackhawk gates, or closer to the San Ramon border near Sycamore Valley, we know the drive times and the house styles. That matters because a 4,000-square-foot multi-zone home with three separate air handlers needs a different crew allocation and equipment load than a compact single-system ranch. We plan for that before we knock on your door.
Our technicians carry shoe covers and drop cloths on every visit, included without asking. We use quieter Rotobrush and Nikro equipment during nap hours when possible, and we work around pets rather than expecting you to board them. Every job is backed by our 365-Day Done Right Promise, stamped on the work order, not offered only if you complain.
Why Morton’s Air Duct Cleaning Is Danville’s Preferred Air Duct Cleaning Company
Danville families call us back because we treat the house like it’s our own. Paul Adeyemi, who leads Morton’s, built this business on the Cedarwell Care Promise: written price before work starts, every time, no exceptions. That matters in a town where the median home value supports high expectations for professionalism.
Our crews know Danville’s housing stock intimately. The 1980s and 1990s executive homes, particularly in and around Blackhawk, feature extensive duct runs that have now aged 30-40 years. Original duct sealant degrades. Joints leak. And because many original owners held these properties long-term, we regularly open systems that haven’t seen professional cleaning in 35 years. We don’t treat that as an opportunity to upsell panic. We treat it as a condition to document, explain, and fix methodically.
Calls are answered by a live person 24/7, not a voicemail tree. Our background-checked, uniformed technicians arrive with the Cedarwell C.A.R.E. values: protect floors first, explain the plan before touching equipment, and leave a photo of the clean-up before driving away. That photo goes to you, not just our files. It’s proof you can show your partner, your realtor, or your own records.
We don’t promise same-day dispatch because duct cleaning is a scheduled, deliberate job. We do promise punctuality, preparation, and no invoice surprises.
Commercial Air Duct Cleaning in Danville
Commercial Air Duct Cleaning in Danville covers everything from small professional offices along Hartz Avenue to the larger residential-scale systems in estate homes that functionally operate as commercial HVAC loads. A typical commercial duct cleaning in Danville runs $800-$2,400 depending on system count, square footage, and accessibility. We schedule these during off-hours when possible to avoid disrupting your business or household routine.
Our process follows NADCA-compliant source-removal methods using HEPA-filtered negative pressure containment. We don’t brush dust around; we extract it. For Danville’s larger homes with commercial-grade equipment, this means isolating each air handler, establishing proper containment, and documenting airflow improvement with before-and-after photos you can actually see.
Multi-Zone Estate Systems
Many Danville properties, especially in Blackhawk and the Diablo Road corridor, contain three or more separate HVAC zones with dedicated air handlers and duct networks. We clean each system individually, with separate containment and separate documentation. Skipping the guest-house zone or the rarely-used upstairs unit leaves a reservoir of Diablo-wind grit that recontaminates the whole house within weeks.
Small Business and Professional Offices
Offices along Railroad Avenue and in the Danville Town Center need clean ducts for employee comfort and equipment longevity, not dramatic claims about health crises. We work evenings and weekends, protect your flooring and furniture with drop cloths, and leave no debris behind. The written price covers the full scope; no per-vent add-ons appear later.
Air Duct Cleaning Services in Danville
Air Duct Cleaning Services in Danville address the unique particulate load created by the town’s position at the eastern base of the coastal hills, where Diablo winds funnel Central Valley dust and pollen directly into residential return-air intakes. A typical full-system residential cleaning in Danville runs $450-$850 for a single-zone home, with per-system pricing for multi-zone properties. Every service includes supply duct cleaning, return duct cleaning, register and grille cleaning, and a visual inspection of accessible components.
We use professional-grade Rotobrush agitation tools paired with Nikro negative pressure extraction systems. This isn’t rental equipment from a big-box store. These are industry-trusted machines designed for source removal without redistributing fine particulate into your living space. For Danville’s 30-40-year-old original ductwork, proper containment matters enormously.
Supply and Return Duct Cleaning
Supply ducts push conditioned air to your rooms; return ducts pull air back to the air handler. Both sides need attention, but the return side typically carries heavier contamination in Danville homes because that’s where Diablo wind-driven dust enters the system. We clean both completely, not just the easily accessible supply registers.
Video Inspection and Documentation
Our crews can provide video inspection of accessible duct runs when the system layout is complex or when you’re evaluating whether cleaning is needed. For the large homes common in Danville, this documentation helps you understand what you’re paying for and proves the work was done. After cleaning, we photograph the clean-up before leaving. You get visual evidence, not just a verbal report.

Trusted Brands We Service in Danville
We clean and service systems using professional equipment from Rotobrush, Nikro, and Abatement Technologies, and we stock common replacement components from Honeywell, Aprilaire, and Guardsman for faster turnaround on Danville jobs. When we find degraded duct sealant or failing register boots in a 1990s Blackhawk home, we don’t need to order parts and return next week. We carry the materials to complete the repair during the same visit, documented on the same written invoice. That efficiency matters when you’re scheduling around work, school pickup, or a household with young children and pets who need their space back.
Common Air Duct Cleaning Problems We See in Danville Homes
- Layered Diablo-wind dust in multi-story duct runs. The oversized, extended duct systems in Blackhawk’s 1980s custom homes collect decades of fine grit from recurring northeast wind events. Because many systems were never cleaned under original ownership, we frequently find accumulation thick enough to restrict measurable airflow.
- Degraded original duct sealant creating recontamination pathways. The mastic and tape used on 1980s-1990s duct joints breaks down after 30+ years of thermal cycling. Leaks at these joints allow unfiltered attic air and wind-driven exterior dust to re-enter the system continuously, undoing the benefit of cleaning if not addressed.
- Skipped zones in multi-system homes leaving active contamination reservoirs. Homeowners sometimes clean only the main-floor system they use daily, neglecting upstairs or guest-house zones. Those untouched systems redistribute particulate through shared wall cavities and return pathways, recontaminating the whole house within a single season.
- Inadequate negative pressure containment during DIY or discount cleaning attempts. Without proper HEPA filtration and sealed extraction, agitation of 35-year-old ductwork simply blows fine particulate into living spaces through leaks and open registers. We’ve been called to remediate these situations, which costs more than doing it correctly the first time.
Pricing for Air Duct Cleaning in Danville, CA
A typical single-system residential air duct cleaning in Danville runs $450-$650. Homes with two systems generally fall in the $700-$950 range, and three-system properties like many Blackhawk estates run $1,050-$1,400. Commercial duct cleaning for small offices or large residential-scale systems starts around $800 and scales with square footage and system complexity.
We price per complete system, not per vent. That matters in Danville’s larger homes, where vent counts can be misleading. A 12-vent system with short duct runs costs less to clean properly than an 8-vent system with 80 feet of extended supply and return trunkline. Our written quote specifies exactly which air handlers, duct zones, and components are included. No per-vent upcharges appear after we arrive. No “disposal fees” or “equipment surcharges” materialize on the final invoice.
Factors that affect your specific price: number of HVAC systems, age and condition of ductwork (older systems may need sealant repair), accessibility of air handlers and trunklines, and whether video inspection or photography documentation is requested. Every estimate is free, delivered in writing, and valid for 30 days. Call (323) 918-4345 to schedule yours.

FAQs About Air Duct Cleaning in Danville
Danville’s direct exposure to Diablo winds means return-air intakes load with Central Valley dust and pollen faster than in coastal Bay Area cities, so most Danville homes benefit from cleaning every 3-4 years rather than the 5-year interval typical for marine-influenced climates. Homes near open hills or with frequent spring and fall wind exposure may need attention every 2-3 years. Call (323) 918-4345 and we’ll evaluate your specific exposure and system age.
Yes, we clean each system as a separate scope of work with isolated containment, separate agitation and extraction cycles, and individual documentation. A Blackhawk home with three zones and original 1980s-1990s ductwork requires this approach; skipping any zone leaves an active contamination reservoir that re-distributes through shared building cavities. Our per-system pricing reflects this properly.
You receive a written invoice with scope details, a 365-Day Done Right Promise stamped on the work order, and a photo of the clean-up before the crew leaves. For multi-system homes or commercial jobs, we can provide before-and-after photos of accessible components and notes on any sealant degradation or joint repairs performed. This documentation is yours to keep for home sale disclosures, warranty claims, or your own maintenance records.
Yes, our Air Duct Cleaning team handles residential-scale commercial systems in large Danville estates and small professional offices with the same NADCA-compliant methods we use on single-family homes. We schedule around your hours, protect floors and furniture, and provide the same written upfront pricing with no per-vent structure. Typical commercial jobs in Danville run $800-$2,400 depending on system count and square footage.
Wildfire smoke that settles in the San Ramon Valley during temperature inversions concentrates fine particulate matter that standard HVAC filters don’t fully capture, loading duct systems with residue that circulates for months after visible smoke clears. This effect is stronger in Danville than in coastal cities because the valley traps smoke rather than letting it disperse. Professional cleaning with HEPA-filtered extraction removes this accumulated residue; we also inspect filter fit and recommend appropriate upgrade options if we find bypass gaps.
Ready to schedule? Call Morton’s Air Duct Cleaning at (323) 918-4345 for a free written estimate. We’ll ask about your home’s systems, your scheduling needs, and any pets or nap schedules we should know about. Then we’ll show up on time, protect your floors, and leave your ducts cleaner than we found them, with the photo to prove it.
