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’re CleanRun Air Duct Cleaning, and we’ve spent more than a decade documenting what actually lives inside the ductwork of this neighborhood. Our crews coordinate dispatch from the brand’s Los Angeles office and serve Northridge directly. If you want a written price and a photo record of every duct run before and after, call (806) 606-6902.
Why CleanRun Air Duct Cleaning Is Northridge’s Preferred Air Duct Cleaning Company
Northridge homes carry a set of duct problems you won’t find three miles west in Chatsworth or south in Encino, and knowing that difference is the whole job. The 1994 earthquake cracked mastic seals across tens of thousands of attics here, and the reconstruction rush that followed left a lot of duct tape where a proper seal should have gone. Tomas Reyes, who leads our team, made the documented photo record a standard deliverable back in 2013 precisely because this neighborhood’s ductwork tells a story you have to see to believe. We write the price down before work starts, every time, under Haven Standard Clause 1.
Local homeowners in Northridge repeatedly tell us the same thing: they’d rather see a photo of a 3-inch debris build-up at the first elbow than hear a vague description of “dirty ducts.” That’s what we deliver. 52,000+ homes served across the Valley, every one with a written price first and a photo record when the crew leaves. Our 365-Day Done Right Promise backs the work in writing. Not as a marketing line. As a clause in the job record.
Our Air Duct Cleaning Services in Northridge
Residential Duct Cleaning
The typical Northridge ranch built between 1955 and 1975 runs forced-air through an attic duct system that was originally sized for heat, then retrofitted for central AC decades later. That retrofit is where the trouble starts. Flex duct runs get crushed, kinked, and disconnected under the wiring and insulation shifts that happen in any attic, and in Northridge the 1994 quake added a whole extra layer of physical disruption. Our residential cleaning covers every supply and return run, the plenum, and the registers, with a camera record of what was inside before and what it looks like after. A full-system residential clean in Northridge typically runs $385-$720 depending on the number of runs and the condition we find.
Supply Duct Cleaning
Supply ducts are the pressurized side of your system, the runs that push conditioned air into your living spaces. In Northridge, supply plenums are where we most often find fiberglass batt insulation being drawn in through joints where post-quake mastic cracked and was never re-sealed. That’s not a cosmetic issue. It means insulation fibers are blowing through your registers and into the air you breathe. We clean the full supply side with Rotobrush agitation tools and HEPA-filtered negative-pressure extraction, then we show you the before-and-after photos of the exact joints where the contamination was entering. Supply-side cleaning alone on a Northridge home typically starts around $225 and rises with the number of runs.
Return Duct Cleaning
Return ducts pull air back to the furnace and are the negative-pressure side of the system. Any leak or disconnection here acts like a vacuum hose pointed at whatever is around it, and in Northridge that often means attic dust, rodent debris, and the fine particulate matter that Santa Ana winds push across the Valley floor from the Santa Susana and Simi Hills. A disconnected return under the slab or in the crawlspace will pull in air that never passes through your filter. Return-side cleaning in Northridge typically runs $200-$400, and we photograph the inside of every return run so you can verify the work.
Commercial Duct Cleaning
Small commercial spaces in Northridge, particularly medical offices along Reseda Boulevard and retail storefronts near the Northridge Fashion Center, accumulate dust and debris on a schedule that residential systems don’t. Foot traffic, longer runtime hours, and the fine dust that blows across the Valley floor combine to load filters faster and coat duct interiors sooner. We clean commercial ducts with the same written-price standard and photo record we use on homes, and we’re happy to provide a Free Second Opinion on any written estimate you’ve already received from another contractor. Commercial jobs are quoted per system, per building, in writing before we start.

Northridge homes carry Honeywell media filters, Aprilaire whole-house purification units, and equipment from a dozen other furnace manufacturers. Our documented Air Duct Cleaning process works around whatever equipment you have, and we stock the common filters and replacement components for Honeywell and Aprilaire systems so we’re not making a second trip. When your blower, coil, or plenum needs attention beyond the ductwork itself, we tell you what we found and what it costs to put right, in writing, before any additional work happens. We also run Abatement Technologies HEPA-filtered negative-air machines on every cleaning job in Northridge.
Common Air Duct Cleaning Problems We See in Northridge Homes
- Post-quake tape failures at duct joints. Duct tape used during the 1994-1996 rebuild wave in Northridge has a service life of about 5-10 years in a hot attic. 25-30 years later, it’s dried, peeled, and letting unfiltered attic air into the system. A basic cleaning will pull out the debris, but sealing is the real fix.
- Fiberglass insulation drawn into supply plenums. The 1994 earthquake cracked mastic at attic duct joints, and many Northridge homes were patched with tape rather than re-sealed. Attic insulation fibers migrate into the supply side and blow out of registers. We document this with a camera before we do anything else.
- Crushed and kinked flex ducts from the AC retrofit era. 1970s flex runs originally designed for heat only collapse or kink under 100°F+ summer AC load. That restricts airflow, forces the blower to work harder, and traps debris in the collapsed section. Sometimes these runs need replacement, not just cleaning.
- Santa Ana dust and ash intrusion through return leaks. During wind events, fine particulate matter from the Santa Susana and Simi Hills blows directly across Northridge. Any disconnected or cracked return run pulls that dust into the house and bypasses the filter entirely. Return-side cleaning plus leak sealing is the combined fix.

FAQs - Air Duct Cleaning in Northridge
The 1994 quake physically cracked and shifted attic ductwork in Northridge, and much of the post-quake repair work used duct tape instead of mastic to re-seal joints. That tape fails after 5-10 years in a hot attic, and 25-30 years later it’s dried and peeled. The result is fiberglass insulation and attic dust being drawn into supply ducts, a contamination pattern that’s measurably more common in Northridge than in Granada Hills or Reseda, which sit farther from the rupture zone. A basic cleaning that doesn’t address the seals is a temporary fix. Call (806) 606-6902 for a written assessment of your specific duct runs.
Yes, a proper cleaning with HEPA-filtered negative-pressure extraction will remove fine Santa Ana dust and wildfire ash from inside your duct runs. The caveat: if your return ducts have leaks or disconnections, new dust will be pulled back in during the next wind event. The right approach is cleaning plus sealing. We use Abatement Technologies HEPA negative-air machines and Rotobrush agitation tools, and we photograph the inside of every run before and after. If you want the dust gone and staying gone, call (806) 606-6902 for a written scope.
The most common signs are uneven airflow between rooms, certain registers blowing weakly while others are strong, and a persistent musty or dusty smell when the system runs. In Northridge specifically, homes rebuilt or repaired between 1994 and 1996 often have flex runs that were installed quickly and have since kinked or separated. We run a camera inspection as part of every cleaning, and we’ll show you the exact footage of any crushed, disconnected, or failed section. If you suspect this in your home, call (806) 606-6902 and we’ll put a written assessment together.
We clean to NADCA standards for source removal: we use agitation tools to dislodge debris, then HEPA-filtered negative-pressure equipment to extract it without blowing it back into your living space. The full process covers supply ducts, return ducts, the plenum, and all registers. On a 1960s ranch off Reseda Boulevard, our techs pulled an attic access panel and found a supply duct joint where the original mastic had cracked during the ’94 quake and was covered only with dried-out duct tape. That job ended with eleven joints mastic-sealed and two crushed flex runs replaced in the crawlspace, all documented with photos. For a written estimate on your Northridge system, call (806) 606-6902.
In most Northridge homes, both sides need attention, but for different reasons. The supply side is where post-quake tape failures let fiberglass insulation into the pressurized air stream. The return side is where leaks pull in unfiltered attic and crawlspace air, including Santa Ana dust. Cleaning only one side leaves the other as a contamination source. We’ll tell you which side is worse after the camera inspection, and we’ll price each side separately so you can decide with a written number in front of you, not a surprise after the fact. Call (806) 606-6902 for an exact, written quote.
