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.
Fast, Reliable Air Duct Cleaning Across Universal City
Air duct cleaning in Universal City, CA runs $425-$860 for a commercial system and $380-$620 for the limited residential stock along Lankershim Boulevard, with most jobs completed in one to two days. The work here is different from what crews see in Studio City or North Hollywood. Universal City sits at the mouth of Cahuenga Pass, where wind patterns funnel Santa Monica Mountains wildfire smoke and chaparral ash directly into rooftop HVAC intakes on hotels, sound stages, and office buildings. That single geographical fact drives nearly everything about how we approach duct cleaning in this zip code. Call (806) 606-6902 for a written price before any work starts.
Key Takeaways:
- Commercial duct cleaning in Universal City typically costs $425-$860 per system, depending on duct run count and contamination level.
- Post-fire ash contamination from Santa Monica Mountains burns is the dominant local failure mode, not ordinary household dust.
- Every CleanRun job includes a documented photo record of every duct run, before and after, delivered as a standard deliverable.
- A fogging “sanitizer” treatment does not remove ash or debris. Mechanical agitation with negative pressure does.
- Written pricing under Haven Standard Clause 1 is delivered before a single panel comes off.
Why Universal City’s Ductwork Gets Dirty Faster Than Flat Neighborhoods
Universal City is effectively a single-campus commercial and entertainment enclave dominated by NBCUniversal. The demand for Air Duct Cleaning here comes almost entirely from hotels, studio office buildings, sound stages, and CityWalk retail, not from single-family homes. And the geography makes those commercial systems uniquely vulnerable. Cahuenga Pass is a natural wind funnel between the San Fernando Valley and the LA basin. When brush fires burn in the Mulholland corridor or the Santa Monica Mountains, the pass channels smoke, ash, and fine particulates straight through Universal City at elevation, where rooftop HVAC intakes sit directly in the debris path.
Flat-terrain neighborhoods like Glendale or West Hollywood see ash settle gradually. Universal City properties see it forced into intakes within hours of a nearby burn. Facility managers here know the pattern: a fire breaks out near Mulholland Drive, and within two days every hillside hotel along the upper Universal Studios terrain is calling for duct cleaning. We have run enough post-fire jobs in this area to know exactly what the camera will show before we even open the first access panel.
Why CleanRun Air Duct Cleaning Is the Commercial Standard in Universal City

Tomas Reyes founded CleanRun Air Duct Cleaning in 2013 with a simple rule: every job gets a written price before work starts and a photo record when the crew leaves. That rule, now Haven Standard Clause 1, matters more in Universal City than almost anywhere else we work. Commercial property managers here answer to ownership groups and brand standards. They cannot accept a technician’s word that the ducts are clean. They need documentation.
We have served 52,000+ homes and commercial properties, every one with a written price delivered before a single panel came off. In Universal City specifically, our crews know the hillside hotel layouts, the rooftop access patterns, and the filter-loading behavior that follows a Santa Monica Mountains fire event. We arrive with professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, and every technician is background-checked, uniformed, and identified by name before setting foot in your mechanical room. The 365-Day Done Right Promise backs every job in writing. If the work is not right, we make it right.

Commercial Duct Cleaning
This is the core of what we do in Universal City. Hotels, sound stages, and office towers along the Universal Studios terrain run HVAC systems far harder than any residential unit. Rooftop intakes pull in whatever the Cahuenga Pass sends through: chaparral ash, construction dust from studio backlot work, brake particulate from the 101. A full commercial clean here means negative-pressure extraction on every duct run, mechanical agitation of caked debris, and a camera inspection before and after. We quote the whole system, not a per-vent teaser price that balloons once the van is on site.

Video Inspection
Before we clean a single duct in Universal City, we run a camera through it. This is not optional. Sound stage managers and hotel engineers in this area need to see what is actually inside the ductwork, not take a technician’s word for it. The camera shows us exactly where the ash deposits are, whether the return side is as contaminated as the supply, and whether there is mechanical damage that cleaning alone cannot fix. Every customer receives the video record as part of the documented photo file. Haven Standard Clause 4: Documented Photo Record on Every Visit.

Return Duct Cleaning
Skipping the return side is the most common mistake we see in Universal City commercial systems. Cahuenga Pass smoke deposits fine particulates throughout the entire system, not just the supply runs. If you clean only the supply ducts, the return ducts re-contaminate the building within days. Our crews clean both sides, every time. We treat the return plenum and every return register with the same negative-pressure extraction and agitation as the supply side, because in this geography, half a clean is no clean at all.

Full System Cleaning
For hillside hotels and studio facilities that have gone through a nearby burn event, we recommend a full system clean: supply ducts, return ducts, the air handler, the blower motor, the plenum, and every register. This is what we ran after a brush fire in the Mulholland corridor on a hillside property along the upper Universal Studios terrain. The rooftop intakes had pulled chaparral ash into both supply and return ducts. A camera inspection showed particulate caked around the air handler and blower motor. We used HEPA-filtered agitation tools and source removal to clear every register, then verified airflow with a MERV-13 filter check before the property reopened its rooms. That is the standard.

Trusted Brands We Service in Universal City

Most commercial HVAC systems in Universal City run on Honeywell controls and Aprilaire filtration. We service both, plus systems built around Abatement Technologies and Guardsman components. Because we work this area repeatedly, our crews know the common configurations in the hillside hotels and the studio office buildings. We do not stock parts for a made-up generic system; we stock what this zip code actually uses. If your building runs Honeywell dampers or Aprilaire media filters, we know the access points and the failure modes. That local familiarity means the job moves faster and the written price is accurate the first time.
Common Air Duct Cleaning Problems We See in Universal City
- Post-fire ash loading in rooftop intakes. After a Santa Monica Mountains or Mulholland corridor burn, hillside hotels and sound stages see filter loading within hours. Failed MERV-rated filters let ash reach the air handler and clog the blower motor.
- Supply-side-only cleaning that misses contaminated returns. Cahuenga Pass smoke deposits are system-wide. Cleaning only supply ducts leaves the building re-contaminating itself within days.
- Fogging “sanitizer” treatments that skip source removal. A chemical mist does not remove trapped ash or microbial growth. Mechanical agitation and negative pressure do. If the debris is still in the duct, the job is not done.
- Deferred filter changes after fire events. Facilities that wait to change filters after a nearby burn find the contamination has already migrated past the filtration point, into the duct runs and around the air handler.
Pricing for Air Duct Cleaning in Universal City, CA

The written price for commercial duct cleaning in Universal City typically runs $425-$860 for a full system, depending on the number of duct runs, the contamination level, and whether the air handler and blower motor require source removal. Residential units along the Lankershim Boulevard corridor, primarily hillside apartments and condos, run $380-$620. Supply-duct-only cleaning on a small commercial system starts around $390. Return duct cleaning adds $130-$240, depending on access. We will not give you a teaser price and then discover new charges once the van is parked. Haven Standard Clause 1: the written price you approve before work starts is the price you pay. Bring us a competitor’s written estimate and we will put our own number next to it, in writing, for free.
The one thing that moves a Universal City commercial quote is post-fire contamination. If a Santa Monica Mountains burn happened within the last 60 days, the system may need more than a standard clean. We will show you the camera footage that justifies any additional work before we ask for approval. No surprises, just documentation. Call (806) 606-6902 for a written estimate.

FAQs - Air Duct Cleaning in Universal City
Universal City sits at the mouth of Cahuenga Pass, which acts as a wind funnel that channels smoke and ash from Santa Monica Mountains wildfires directly into rooftop HVAC intakes. Flat-terrain neighborhoods like West Hollywood or Glendale see ash settle gradually on horizontal surfaces. Universal City’s hillside hotels and studio buildings have intakes positioned at the exact elevation where the pass deposits airborne debris. A fire in the Mulholland corridor almost always generates a wave of commercial duct cleaning calls to this zip code within days. If your property has not been cleaned since the last nearby burn, schedule an inspection now. Call (806) 606-6902.
No. A fogging treatment mists a chemical into the ductwork but leaves the ash, soot, and particulate debris in place. In Universal City’s post-fire conditions, the problem is physical contamination: chaparral ash caked on duct walls and around the air handler. That requires mechanical agitation and negative-pressure extraction to physically remove the debris. Fogging without source removal is like spraying air freshener in a room without taking out the trash. A genuine clean leaves the ducts visibly different on camera. We document that difference in the photo record on every job.
Within 48 to 72 hours if your building’s HVAC system continued running during the smoke event. Universal City properties at hillside elevation see filter loading within hours of a nearby burn. Once filters saturate, particulates pass through to the duct runs, the air handler, and the blower motor. Waiting a month means the contamination has had time to bond to duct surfaces and work its way deeper into the system. The sooner we can run a camera inspection, the cleaner the remediation. Call (806) 606-6902 after any nearby burn and we will schedule the inspection, with a written price before any work begins.
Yes, in two ways. First, residential systems in Universal City are smaller and simpler: fewer duct runs, lower static pressure, less contamination by volume. Second, those hillside apartments and condos still sit in the same Cahuenga Pass wind pattern, so post-fire ash events affect them just as much as the commercial towers. The cleaning is mechanically the same, but the scope is smaller and the price reflects that. Residential units along the Lankershim corridor typically run $380-$620 for a full system clean. We quote every job, residential or commercial, with a written price before work starts.
You should see the inside of every duct run, clearly lit and recorded, before and after cleaning. The report should identify specific locations: the supply plenum, each supply duct run, each return run, the air handler, and the blower motor. If a crew cannot produce video of the return side, they probably did not clean it. Our video inspections show the debris before source removal and the clean duct surface after. We do not summarize what the camera saw; we give you the footage. That is the standard documentation every Universal City property manager should demand.
