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’ve worked the tract homes off Stevenson Ranch Parkway and the larger hillside properties near the Santa Clarita Valley’s rural edge long enough to know what fails here and why. The master-planned construction of the 1980s and 1990s means entire streets share the same aging flexible ductwork, the same collapsed runs behind upstairs registers, and the same dust loading from unpaved roads and open land. That pattern is predictable, and we price for it honestly.
Why Hollis Air Duct Cleaning Is Stevenson Ranch’s Preferred Air Duct Cleaning Company
Our Air Duct Cleaning team has built a reputation in Stevenson Ranch by showing up uniformed, background-checked, and ready to explain what we find before we quote the fix. Homeowners here are not looking for the lowest teaser price; they’re looking for the price that stays put when the van is in the driveway. We write it down before we start, and it does not move.
Dispatch and scheduling for Stevenson Ranch are coordinated from our Los Angeles office, but the crews serving you are local to the Santa Clarita Valley and know the area’s housing stock. They understand that a two-story tract home near Pico Canyon Road faces different duct failure modes than a hillside property off The Old Road with longer supply runs and more exposure to dust.
Every job carries our 365-Day Done Right Promise in writing. If the work fails within a year, we return and make it right at no charge, including a free second visit. No negotiation, no runaround. Phones are answered by a live person 24 hours a day, 7 days a week.
Air Duct Repair in Stevenson Ranch
Air Duct Repair in Stevenson Ranch almost always involves the original flexible duct runs installed during the 1980s and 1990s tract construction, now disintegrating or crushed flat behind walls and upstairs registers. When a blower motor pulls high amps against that restriction, you’re paying more in electricity for less airflow. A typical repair runs $200 – $500 per affected zone, with full system replacements reaching $1,500 – $3,500 depending on access and square footage.
Collapsed Flex Duct Behind Upstairs Registers
This is the failure we see most. The original flex duct was strung tight through attic trusses and has simply gone flat with age. We cut access, remove the collapsed material, and replace with properly supported new ductwork sized to the register’s CFM requirement.
Disintegrating Duct Seams and Connections
The mastic and tape used in 1990s construction has dried and failed. We reseal with modern duct sealing mastic or replace sections where the damage is too extensive, then test static pressure to confirm the system is breathing properly again.
Ductwork Cleaning in Stevenson Ranch
Ductwork Cleaning in Stevenson Ranch addresses the fine dust, pollen, and wildfire particulate that loads supply and return ducts year-round, especially in homes near the rural edge with longer drives on unpaved roads and more exposure to open land. A full system cleaning runs $350 – $650 for most 1,500 – 3,500 sq ft homes, with larger hillside properties up to $850. We use Rotobrush rotary brush systems and Nikro negative-air machines with HEPA filtration, the same equipment commercial crews run.
Source Removal for Wildfire Smoke and Dust Loading
Santa Clarita Valley’s hot, dry summers push HVAC systems to run constantly, and wildfire smoke from the Angeles National Forest routinely infiltrates return ducts. Our process agitates the debris loose, maintains negative pressure so nothing escapes into your living space, and captures it in HEPA-filtered collection. We show you before-and-after photos of your own ducts.
Air Handler and Blower Motor Cleaning
Fine dust bypasses standard filters and coats the blower motor and evaporator coil, reducing efficiency and circulating debris back through clean ducts. We clean the full air handling unit as part of our complete system service, not as an upsell.
Trusted Brands We Service in Stevenson Ranch
We stock parts and filtration products from Aprilaire, Abatement Technologies, and Guardsman for Stevenson Ranch customers, which means faster turnaround when a component needs replacement and no waiting on special orders. Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation and Nikro negative-air machines for controlled debris extraction. If your system uses Honeywell or Aprilaire filtration, we carry those media replacements and can advise on upgrade options that fit your existing cabinet without modification. Every brand we mention is one we actually install, service, and stand behind with our written guarantee.
Common Air Duct Cleaning Problems We See in Stevenson Ranch Homes
- Identical flex-duct failures across entire tracts. Because Stevenson Ranch was built as a master-planned community in the 1980s and 1990s, entire neighborhoods share the same original ductwork. Our crews routinely find the same collapsed flex runs on house after house along the same street, rather than the scattered, varied failures seen in older parts of LA County.
- Rural-edge dust and pollen loading. Properties near the hilly sections and open land around Stevenson Ranch face fine dust infiltration from unpaved roads that standard 1-inch filters cannot stop. This debris coats blower motors and evaporator coils, reducing system efficiency even before ducts are visibly dirty.
- Wildfire smoke infiltration during summer HVAC overload. Hot, dry Santa Clarita Valley summers keep systems running continuously, and smoke from the Angeles National Forest enters return ducts through gaps and negative pressure. Without seasonal cleaning, odor and particulate recirculate for months.
- Weak airflow to upstairs registers in two-story tracts. The original 1990s flex duct runs to second-floor registers were often strung with minimal support and have flattened or torn. Homeowners notice this as hot upstairs bedrooms or a system that never reaches setpoint despite running constantly.
Pricing for Air Duct Cleaning in Stevenson Ranch, CA
Most full-system duct cleanings in Stevenson Ranch fall between $350 and $650 for homes in the 1,500 – 3,500 sq ft range, with larger hillside properties up to $850. Air duct repair runs $200 – $500 per zone for localized collapsed flex duct, and full system replacements reach $1,500 – $3,500.

Cost drivers here include square footage, number of HVAC zones, accessibility of attic duct runs, and whether we find disintegrating flex that requires repair before cleaning is worthwhile.

FAQs About Air Duct Cleaning in Stevenson Ranch
Every 2 – 3 years for most Stevenson Ranch homes, and every 18 – 24 months for properties near unpaved roads or open land with heavier dust and pollen loading. Wildfire smoke seasons may warrant an additional inspection. Call (361) 326-5060 to schedule.
Nearly never. Stevenson Ranch’s homes were built after California’s 1975 ban on asbestos in duct insulation, so original ductwork here does not contain the asbestos-laden materials still found in older Los Angeles County properties. If we encounter any suspect material during inspection, we stop work and advise on proper testing.
Because the original 1980s – 1990s flexible duct runs to second-floor registers have likely collapsed flat with age. This is the most common duct failure we see in Stevenson Ranch tracts, and it chokes airflow while forcing your blower motor to work harder. Repair typically runs $200 – $500 per affected zone.
Yes. Smoke particulate from the Angeles National Forest and Santa Clarita Valley wildfires infiltrates return ducts during hot, dry summers when HVAC systems run constantly. Without cleaning, these odors and particles recirculate indefinitely. Seasonal duct cleaning removes the residue and restores indoor air quality.
They do if they have dedicated duct systems or mini-split connections. We price additional systems separately upfront, not as hidden add-ons. Many Stevenson Ranch hillside properties have workshop or guest house systems that accumulate the same dust loading as the main house.
