Fast, Reliable Air Duct Cleaning Across Chatsworth
Air duct cleaning in Chatsworth runs $425 to $780 for a typical single-system ranch home, and $900 to $1,650 for larger estates with multiple air handlers and zoned ductwork. We give you that price in writing before any work starts, and it does not move at the door. This matters in Chatsworth more than most places, because the mid-century ranch homes scattered across the 91311 zip code often have original 1950s-to-1970s metal ducts that have never been replaced, and the Santa Ana winds push fine dust from the Santa Susana Mountains through every crack and seam. Call (661) 523-0295 and you will get a live person on the line, not a voicemail loop. We know this area, we know these houses, and we know what it takes to get baked-on attic dust out of ductwork that most homeowners have never seen.
Why Hollis Air Duct Santa Clarita Is Chatsworth’s Preferred Air Duct Cleaning Company
Hollis Air Duct Cleaning operates under the Garrison Partners family with The Garrison Standard behind every job: arrive inside the quoted window, put the price in writing before touching anything, complete the work by the book, and leave the site clean. Roy Castellanos leads the crew, and the technicians who walk through your door are background-checked and uniformed. You will know who is in your home before they arrive. We have been doing this since 2004, and in Chatsworth specifically, homeowners tell us the same thing over and over: other companies gave them a low per-vent teaser price, then the invoice tripled once the technician started pulling registers. That does not happen with us. The price is written, it is for the whole system, and it is the price you pay.
When we service homes around Lake Manor, the Santa Susana Pass area, or the neighborhoods west of Mason Avenue, we account for what those properties actually have: original metal supply and return ducts running through uninsulated attics that bake all summer. That changes the cleaning method. That changes the time on site. And it changes the documentation we hand back. Residents who have compared notes with friends in Porter Ranch or Northridge know that Chatsworth homes run a little different because of the hills and the heat.
Styles & brands we work with
Commercial Air Duct Cleaning in Chatsworth
Commercial Air Duct Cleaning in Chatsworth covers office suites, retail spaces, medical offices, and the small industrial shops that line De Soto Avenue and the commercial corridors near the 118 Freeway. The job involves running a camera through the full duct network first, then using negative-air machines to pull debris out while rotary brush systems agitate the duct walls. Commercial jobs in Chatsworth typically run $1,100 to $2,800 depending on the square footage, the number of rooftop units, and how much dust has accumulated inside the runs. We schedule commercial work during off hours when needed, so a retail shop or dental office on Topanga Canyon Boulevard does not have to close for a day.
Full System Cleaning
This means exactly what it sounds like: supply ducts, return ducts, plenums, and the air handler itself all get serviced in one job. For a commercial space in Chatsworth, skipping the return side is a common mistake that leaves the system recirculating the same dust you just paid to remove. Full system cleaning on a commercial property usually runs $1,300 to $2,800, and it takes a half day to a full day depending on system size.
Video Inspection
Before any cleaning starts, we run a camera through the ducts and record what it finds. You see the footage. You know what was in there before we touched it. After the job, we run the camera again. If a commercial tenant in Chatsworth has been complaining about dust settling on desks within a day of janitorial service, the before-and-after video usually shows why.
Air Duct Cleaning Services in Chatsworth
Air Duct Cleaning Services in Chatsworth focus on the housing stock that defines this corner of the San Fernando Valley: mid-century ranch homes with original metal ductwork, and newer hilltop estates with zoned systems that run three air handlers or more. The work starts with a camera inspection, then moves to negative pressure to create suction, then rotary brush agitation to break the dust crust off the duct walls. For a standard single-system Chatsworth ranch, the full job runs $425 to $780. A three-system custom home up in the hills around Woolsey Canyon or along Valley Circle Boulevard runs $900 to $1,650. Every job gets a written price before work begins, and every job is covered by the 365-Day Done Right Promise: if the work fails within a year, we come back and make it right at no charge.
Supply Duct Cleaning
Supply ducts are the runs that carry conditioned air from the furnace or air handler out to each room. In Chatsworth, these ducts often run through attics that hit 130 degrees or more in August, and that heat bakes dust onto the metal from the inside. Supply duct cleaning on a ranch home is part of the full-package price above. We do not do per-vent add-ons.
Return Duct Cleaning
Return ducts pull air back to the air handler, which means they see all the dust, pet hair, and Santa Ana grit that gets pulled into the system. On older Chatsworth homes, we often find the return side more contaminated than the supply side, because returns in 1950s and 1960s homes were frequently undersized and pulled hard against dirty registers. Return ducts get the same agitation and negative-pressure treatment as the supply side. It is the same written price, not a separate line item.
Residential and Commercial Duct Sealing
Some Chatsworth homes lose 20 to 30 percent of conditioned air through leaky duct joints and separations in attic runs. That is not a guess; that is what our camera finds on a regular basis in this housing stock. We offer Air Duct Cleaning and sealing as a combined service, using mastic and metal tape at the joints after cleaning. A sealed system costs about $250 to $450 to add on a ranch home, and it means the air you paid to cool stays in the house instead of blowing into the attic above Lassen Street.

Trusted Brands We Service in Chatsworth
Our crews run professional-grade equipment from Rotobrush rotary brush systems and Nikro negative-air machines. When duct sealing or filtration upgrades come up, we work with Honeywell and Aprilaire products. That is not a hardware-store setup. It is the same class of gear commercial crews use on multi-tenant buildings, and it is why we can handle the compact, baked-on dust found in Chatsworth attic ducts instead of just loosening the surface layer and leaving the crust behind. We keep common filters and sealing materials stocked on the trucks dispatched to Chatsworth, so most jobs do not need a second trip for parts.
Common Air Duct Cleaning Problems We See in Chatsworth Homes
- Baked-on dust crust in uninsulated attics. Summer attic temperatures in Chatsworth routinely exceed 130 degrees, and that heat turns fine Santa Susana dust and skin-oil residue into a hard coating on the inside of metal ducts. Standard brush agitation skims the surface; fully removing it takes longer and more aggressive source removal, which changes how the job is priced and scheduled.
- Original 1950s-to-1970s metal ducts that have never been serviced. Many ranch homes on streets like Devonshire Street or Lassen Street still run the same metal supply and return lines installed when the house was built. The duct joints are often loose, the interior is caked, and the system has never been balanced for modern air handlers.
- Cross-contamination in multi-zone homes. When a Chatsworth estate has two or three air handlers, cleaning only one zone or skipping the return side pushes debris from one part of the house into another. We clean supply and return ducts separately on every system, and we document each one in the photo log.
- Santa Ana dust loading that returns weeks after a cheap cleaning. The Santa Ana winds push fine grit from the Santa Susana Mountains into Chatsworth neighborhoods several times a year. If a cleaning used low-suction equipment or skipped the air handler cabinet, the dust settles back into the ducts within a month or two. That is why our written price includes the full path, not just the register openings.

FAQs About Air Duct Cleaning in Chatsworth
In Chatsworth, every two to four years is the practical range, which is more frequent than coastal areas but in line with the hotter, dustier parts of the northwest Valley. The Santa Susana Pass geography means Santa Ana winds cycle fine dust through homes several times a year, and uninsulated attics bake that dust hard between cleanings. If you have not had the ducts cleaned in five years or more, start with a camera inspection. Call (661) 523-0295 and we will schedule it.
Three separate duct systems usually means three air handlers, one per zone or floor, which is common in larger custom estates built in the Chatsworth hills and in some expanded mid-century ranches. Pricing goes by the whole system, so a three-system house costs more than a single-system ranch because the job takes longer and covers more duct surface area. The price you get is written before work starts and it covers every system, supply and return, in one number. Call (661) 523-0295 for a written quote on your layout.
You should expect a before-and-after video or photo log of your actual ducts, taken with a camera inspection tool, plus a written invoice that shows the system count and the work performed. We cleaned a three-system house on Lassen Street near Mason Avenue where the original metal ducts had never been serviced. Our camera inspection showed baked-on dust inside the return ducts, so we used Rotobrush agitation tools and negative pressure to pull crusted debris out of the supply and return ducts. After cleaning, we resealed the registers and left the homeowner a before-and-after photo log so they could see what was removed from ductwork they cannot access. That is the standard we hold on every Chatsworth job.
Cleaning the ducts will reduce the dust that gets blown out of the registers when the system runs, but it will not stop dust from entering the home through windows, doors, and attic gaps during a strong Santa Ana event. What it does is stop the system from recirculating the dust that settled inside the ducts over years of wind events. Duct Sealing - Chatsworth helps too, and we can give you a written price for cleaning and sealing together. Call (661) 523-0295.
Yes. Original 1950s-to-1970s metal ducts in Chatsworth ranch homes frequently sit in uninsulated attics, and the summer heat bakes fine dust into a crust that standard brush cleaning will not fully remove. We use higher-agitation Rotobrush tools and longer dwell times with negative pressure to break that crust loose. The method is different because the condition is different, and a technician who treats it like a coastal job will leave debris behind. Our written price accounts for the extra time before we start.
