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 Duarte
Air duct cleaning in Duarte typically runs $350-$650 for a full residential system and $800-$1,800 for commercial properties, with most jobs scheduled within a few days of your call. We’re Morton’s Air Duct Cleaning, and our crews work Duarte regularly, from the post-war tracts near Royal Oaks Park to the hillside streets below the San Gabriel Mountains. Dispatch and scheduling are coordinated from our Los Angeles office, but the technicians who arrive at your door know Duarte’s housing stock, its wind patterns, and the specific contamination we find here. Call (323) 918-4345 for a free written estimate before any work begins.
Why Morton’s Air Duct Cleaning Is Duarte’s Preferred Air Duct Cleaning Company
We’ve been part of the Cedarwell family since 2005, and our reputation in Duarte has been built one home at a time. Homeowners here talk to each other, and they mention the same things in reviews: our crew noticed the dog bed in the corner and worked around it, they laid drop cloths before touching anything, and the price on the invoice matched the written quote exactly.
Our response time to Duarte is typically two to four days for standard scheduling, sometimes sooner depending on route density. We know the difference between a 1950s Royal Oaks tract home with original sheet-metal ductwork and a 1970s split-level with early flex-duct retrofits. That local knowledge means we show up with the right equipment and the right expectations, not a generic checklist.
Every visit is backed by our 365-Day Done Right Promise. If something isn’t right, we make it right. No expiration date, no fine print.
Air Duct Inspection in Duarte
Air Duct Inspection in Duarte is where we always start, because Duarte’s housing stock demands it. A typical residential inspection runs $150-$250 and includes a full video scan of your supply and return runs, assessment of the air handler and blower assembly, and a written report with photos. For Duarte homes, we’re specifically looking for separated joints in original sheet-metal ductwork, collapsed flex-duct sections from 1980s retrofits, and the distinctive grayish-white ash residue from the 2020 Bobcat Fire that still lingers in north-Duarte return plenums.
What the Camera Reveals
Our video inspection uses a lighted, articulating camera that travels through your duct runs and records what we find. In Duarte, that often means documenting decades of accumulated debris, cracked fibrous-glass lining, or the ash layer that compressed-air cleaning alone won’t touch. You see the footage. We explain what it means. Then we write the price.
The Written Report
Every inspection concludes with a printed or emailed report: photos, findings, recommended scope of work, and one flat price for the full system. No per-vent add-ons, no surprises after we start. In Duarte’s older homes, we frequently recommend sealing separated joints as part of the cleaning scope, since agitation without sealing just lets the same contamination back in next Santa Ana season.
Residential Air Duct Cleaning in Duarte
Residential Air Duct Cleaning in Duarte addresses a specific set of problems you won’t find in newer coastal communities. A typical full-system clean for a single-family home runs $350-$650, with larger homes or systems requiring extensive sealing work reaching $750-$950. The job includes HEPA-contained negative-pressure cleaning of all supply and return ducts, agitation with professional brushes and compressed-air tools, camera verification, and, for north-Duarte homes near the foothills, enzymatic deodorizing treatment when Bobcat Fire residue is present.
Working Around Your Household
We schedule with your family’s rhythm in mind. Nap hours mean quieter tool settings where possible. Pets stay in their familiar spaces; we work around them rather than asking you to board them. Shoe covers and drop cloths are standard on every visit, part of the Cedarwell Care Promise, not an upgrade.
Sealing as the Real Fix
Cleaning removes what’s there now. Sealing keeps it from coming back. In Duarte’s post-WWII tracts, we regularly find supply ducts separated at attic joints, pulling hot attic air and chaparral dust straight into your living space. We re-seal with mastic and metal tape rated for ductwork, not the hardware-store stuff that dries and fails in two summers.
Trusted Brands We Service in Duarte
Our trucks carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, the same brands specified by commercial HVAC contractors, not the rental-grade units sold to homeowners. Rotobrush’s brush-and-vacuum systems handle the agitation and extraction in Duarte’s older sheet-metal and fibrous-glass-lined ducts. Nikro’s HEPA-contained negative-air machines maintain proper pressure differential so contamination doesn’t escape into your home during cleaning. Abatement Technologies filtration captures the fine particulate that Santa Ana winds drive into Duarte’s duct systems. We stock common fittings and sealing materials locally, so if we find a separated joint or crushed flex run during your clean, we can address it same visit rather than rescheduling.
Common Air Duct Cleaning Problems We See in Duarte Homes
- Original sheet-metal joints separate in attic runs. Duarte’s post-WWII tract homes were built with sheet-metal ductwork that expands and contracts through decades of San Gabriel Valley heat cycles. The joints separate, and Santa Ana winds push chaparral dust and mountain grit straight into your supply air. We find this in maybe half the 1950s and 1960s homes we inspect.
- Early fibrous-glass lining cracks and sheds. The fibrous-glass insulation inside original ducts becomes brittle after 50-plus years. It cracks, exposing raw fiber to the airstream, and the cracks become debris collection points. Agitation without proper containment makes this worse, which is why we run negative pressure on every job.
- 1980s flex-duct retrofits collapse in attic and crawl spaces. Many Duarte homes got flex-duct additions or replacements in the 1980s. That flex has sagged, torn, or collapsed entirely, creating contamination traps that choke airflow and harbor mold-friendly moisture pockets. We camera-locate these before we quote, so you know what’s actually wrong.
- Bobcat Fire ash residue persists in north-Duarte return plenums. Homes near the hillside, especially streets off Mount Olive Drive and north of Royal Oaks, still have a grayish-white ash layer in their return plenums from the 2020 fire. Standard compressed-air cleaning won’t remove the faint smoke odor. Enzymatic deodorizing treatment does, and we include that assessment in every north-Duarte inspection.
Pricing for Air Duct Cleaning in Duarte, CA
Here’s what honest pricing looks like for Duarte’s market. A typical residential full-system cleaning runs $350-$650 for homes up to about 2,500 square feet with standard duct configurations. Larger homes or systems with extensive sealing needs reach $750-$950. Commercial duct cleaning in Duarte’s retail and office spaces starts around $800 and ranges to $1,800 depending on system complexity and access. Video inspection alone is $150-$250, credited toward your cleaning if you proceed.
What moves you within these ranges: number of supply and return vents, accessibility of duct runs (crawl space vs. walkable attic), extent of sealing work needed, and whether enzymatic deodorizing is required for fire residue. We give you one flat price per system, agreed in writing, before any work starts. No per-vent pricing. No add-ons after the van is in your driveway. Call (323) 918-4345 for your exact quote.

FAQs About Air Duct Cleaning in Duarte
The 2020 Bobcat Fire left a grayish-white ash layer in north-Duarte return plenums that standard compressed-air agitation doesn’t fully remove, and that residue can carry a faint smoke odor for years. Enzymatic deodorizing treatment breaks down the odor compounds at a molecular level, which is why we assess for this specifically in hillside-adjacent homes and include it in our scope when needed. Call (323) 918-4345 and we’ll check your plenum with a camera before we quote.
Original sheet-metal supply runs with separated joints at attic connections, cracked fibrous-glass lining shedding fibers into the airstream, and decades of accumulated dust compounded by Duarte’s higher particulate load from Santa Ana wind events. We camera-inspect first, then quote sealing and cleaning together since sealing is usually the fix that lasts. Estimates are free at (323) 918-4345.
Yes, frequently. The flex-duct installed in many Duarte homes during the 1980s has sagged, torn, or collapsed in attic and crawl-space runs, creating airflow restrictions and contamination traps that standard cleaning can’t address without repair or replacement. We locate these with our inspection camera and include repair options in your written quote before we start any work.
Duarte’s position where the San Gabriel Valley narrows toward the foothills creates a direct funnel for Santa Ana winds, driving fine chaparral dust, mountain grit, and fire-season ash into home interiors and through HVAC return grilles. Combined with the South Coast Air Basin’s high PM2.5 readings, ducts here accumulate visible contamination faster than homes just 15 miles west toward Pasadena. Most Duarte families benefit from inspection every three to five years, with cleaning scheduled based on what we find.
