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.
Air Duct Cleaning Company in Duarte, CA
Air duct cleaning in Duarte is a job shaped by where the city sits: tucked tight against the San Gabriel Mountains, right in the path of Santa Ana winds and the South Coast Air Basin’s heaviest particulate drift. Homes here, most built between the late 1940s and early 1970s, still run on original sheet-metal or early fiberglass-lined ductwork that has had decades to collect that mountain grit along with smoke residue from the 2020 Bobcat Fire. Morton’s Air Duct Cleaning handles those older Duarte systems with professional Rotobrush and Nikro equipment, a written price before any work starts, and the 365-Day Done Right Promise behind every visit. Call (323) 918-4345 for a free estimate.
Why Duarte Homes Are Different
Duarte sits where the San Gabriel Valley narrows toward the foothills, which means the city acts as a natural funnel for Santa Ana wind events. When those winds kick up, they push fine chaparral dust, mountain grit, and during fire season, ash straight through return grilles and into HVAC duct runs. Combined with the air basin’s consistently high PM2.5 readings, ducts in Duarte accumulate visible contamination noticeably faster than homes just 15 miles west toward Pasadena. We see it on nearly every job: a fine gray-brown film coating the inside of return plenums that coastal LA homes rarely develop in the same timeframe.
Then there’s the housing stock itself. Duarte’s core residential streets are dominated by post-WWII tract homes, many still carrying original sheet-metal ductwork from the late 1940s through the early 1970s. Those ducts were well built for their era, but seams separate, joints pull apart, and early fibrous-glass linings crack over time. Some systems include 1980s flex-duct retrofits with collapsed sections that trap debris and choke airflow. It’s not unusual for us to find a return plenum in Royal Oaks or along Huntington Drive holding a layer of Bobcat Fire ash that standard compressed-air cleaning alone won’t fully resolve. When that residue carries a faint smoke odor, the job calls for an enzymatic deodorizing treatment, something we handle with equipment from Abatement Technologies.
Our Main Duarte Services
Most Duarte homeowners call us for two things: cleaning the supply and return ductwork that moves air through the house, and clearing dryer vents that have accumulated lint and, in some foothill neighborhoods, fine ash and dust. Both have their own Duarte page with full pricing and job details.
Air Duct Cleaning in Duarte
Air Duct Cleaning in Duarte means working around systems that are often 50 to 70 years old. We inspect the full duct run first, then clean supply and return lines, replace filters where needed, and photograph everything after. In northern Duarte streets closest to the hillside, we watch specifically for that grayish-white Bobcat Fire ash layer inside return plenums and treat it with enzymatic deodorizer when smoke odor lingers. Our crews bring Rotobrush and Nikro equipment, lay down drop cloths, and wear shoe covers from the front door to the attic access. Written price first, always.

Dryer Vent Cleaning in Duarte
Dryer Vent Cleaning in Duarte matters more than most homeowners realize, especially in older Duarte homes where dryer vents run long horizontal distances through attics or crawl spaces. Lint builds up, but so does the same fine dust and ash that coats HVAC ducts here. We clean the full vent run from dryer to exterior termination, check for crushed or disconnected sections common in those 1980s flex retrofits, and leave a photo of the cleaned vent at the exterior exit point. One flat price per vent run, agreed before we start.

What Duarte Customers Say
"New house, old dusty ducts. They were gentle in the house, laid down drop cloths, and double checked every register was sealed back up. Air smells fresh now."
- Scott Hemmings"Friendly, calm crew that clearly cared about the house. Covered their shoes, protected the floors, and double checked they'd closed up every vent cover properly. Would have them back."
- Omar Zaid"Ducts and dryer vent both. They put runners down the whole hall and wore booties. Spotless after, and they showed me photos of what came out. Worth every penny."
- Bonnie Vo
