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 been working in Santa Monica long enough to know the local ductwork by its problems. The marine layer that rolls in off the Pacific doesn’t just keep your windows open, it pushes salt-laden air through every register and return. That salt binds with coastal pollen and moisture into a stubborn film that standard vacuuming won’t touch. Our Air Duct Cleaning team treats Santa Monica homes differently because the conditions here are genuinely different from what you’ll find twenty miles inland.
Why Hollis Air Duct Cleaning Is Santa Monica’s Preferred Air Duct Cleaning Company
Hollis has built its reputation in Santa Monica on showing up inside the quoted window, pricing the job in writing before any equipment touches the ductwork, and leaving the site clean. We’re part of the Garrison Partners family, founded in 2004, and every Hollis location operates independently under The Garrison Standard. That means written prices, written guarantees, and technicians who follow The Garrison Code on every job.
Our Santa Monica customers aren’t looking for the lowest teaser price. They’re looking for a crew that won’t renegotiate at the door. The 365-Day Done Right Promise covers every job in writing: if the work fails within a year, we return and make it right at no charge, including a free second visit. Background-checked, uniformed technicians arrive in marked vehicles. Phones are answered by a live person 24 hours a day, seven days a week. No voicemail loops. No callback queues.
We know the local housing stock. Ocean Park’s 1920s bungalows with gravity furnaces and short, odd duct runs. The 1960s – 70s apartments in the Wilshire corridor with rooftop air handlers and flex duct that traps coastal dust. Rent-controlled buildings near Pico where shared vertical chases haven’t been touched in decades. That knowledge changes how we approach the job, what we inspect first, and what we warn you about before we start.
Air Duct Cleaning Services in Santa Monica
Air Duct Cleaning Services in Santa Monica address a specific coastal problem: salt air, marine-layer moisture, and seasonal desert dust combine inside ductwork to create adhesive grime that plain vacuuming won’t remove. A proper cleaning here requires agitation tools, negative-air containment, and inspection for corrosion damage that inland crews rarely encounter. For a typical Santa Monica single-family home, expect $350 – $550; larger homes or systems with multiple zones run $500 – $650.
Residential Duct Cleaning
We clean the full supply and return network, from the main trunk to each branch line and register. In Santa Monica’s older homes, we often find original metal duct boots corroding at the register frame and flexible connectors turning brittle from salt exposure. Our process includes video inspection before and after, so you see what came out and what condition the metal is in.

Commercial and Multi-Unit Cleaning
Shared HVAC systems in Santa Monica’s apartment buildings accumulate debris from multiple units and decades of deferred maintenance. We coordinate with property managers to access rooftop and closet air handlers, clean vertical chases between floors, and document conditions for maintenance records. Pricing starts around $800 for smaller buildings and scales with system complexity.

HVAC Duct Cleaning in Santa Monica
HVAC Duct Cleaning in Santa Monica means dealing with systems that run more months of the year than inland equivalents, because there’s no hard freeze to drive homeowners to seal up and run constant heat. The result is continuous airflow pulling salt, pollen, and moisture through the same ducts year-round. A full HVAC duct cleaning for a Santa Monica home typically runs $400 – $600 and includes the air handler, coils, and full supply and return network.
Negative-Air Method with HEPA Filtration
We seal the system and pull continuous negative pressure through the ductwork while agitating debris with rotary brushes. This captures loosened material at the source rather than blowing it into your living space. For Santa Monica’s sticky coastal buildup, the negative-air method is essential. Vacuum-only cleaning redeposits the adhesive film within weeks.
Video Inspection and Documentation
Our techs run a camera through the main trunk and branch lines before starting work and again after completion. You see the salt crust, the corrosion points, the accumulated debris. In Santa Monica, this documentation often reveals flex connectors and boots that need replacement, not just cleaning. We note those in writing and price any additional work before proceeding.
Trusted Brands We Service in Santa Monica
We carry professional-grade equipment from Rotobrush and Nikro, the same rotary brush systems and negative-air machines used in commercial jobs across Los Angeles County. For filtration upgrades and replacements, we stock Honeywell, Aprilaire, and Guardsman products sized for Santa Monica’s mix of vintage bungalows and mid-century apartment systems. Parts are sourced through local suppliers, so replacement filters, register boots, and flex connectors don’t add days to the schedule. If your system needs a component we don’t have on the van, we’ll tell you exactly when it arrives and what it costs before ordering.
Common Air Duct Cleaning Problems We See in Santa Monica Homes
- Salt corrosion on metal duct boots and register frames. In beach-adjacent blocks of Ocean Park and north of the bluffs, onshore breeze and marine-layer dampness coat the insides of metal duct boots and register frames with a white, crusty salt residue that inland Los Angeles duct systems simply do not develop, and it corrodes the metal while it sits there.
- Brittle flex connectors at air handlers. The same salt air that crusts metal boots also degrades flexible duct connectors, especially in closet and rooftop installations common in the Pico and Wilshire corridors. A brittle connector leaks conditioned air and pulls unfiltered attic or closet air into the system.
- Adhesive grime from marine-layer moisture binding coastal pollen and mold. Because the damp air keeps salt residue slightly tacky, it binds coastal pollen and mold spores into an adhesive grime that resists a plain vacuum pass. Techs who treat Santa Monica ductwork as dry-dust cleaning leave this film intact.
- Decades of accumulated debris in shared multi-unit chases. Rent-controlled buildings near Pico and along the Wilshire corridor often delay maintenance, so vertical supply and return chases between floors become reservoirs for dust, skin cells, and construction debris from decades of tenant turnover.

FAQs About Air Duct Cleaning in Santa Monica
Santa Monica’s year-round marine layer and open-window lifestyle mean ducts act as continuous filters for salt air, coastal pollen, and moisture, while seasonal Santa Ana winds add desert dust and fire ash. The resulting buildup is darker, more adhesive, and more corrosive than typical household dust, and it accumulates faster than in drier inland climates where windows stay closed for months. Call (361) 326-5060 to schedule an inspection and see what your system looks like inside.
Salt air corrodes exposed metal duct boots, register frames, and flexible duct connectors, producing white crusty residue and brittle, cracking rubber or plastic. You’ll notice it as a recurring gritty or musty smell when the marine layer rolls in, or visible white bloom around register edges when you remove the cover for cleaning. Our techs inspect for this on every Santa Monica job and document corrosion with before-and-after photos. Call (361) 326-5060 for an exact quote.
No. A fogging sanitizer or deodorizer does not remove the debris, salt crust, or corroded connectors that cause coastal duct odors. It masks smells temporarily while the actual problem remains. A genuine clean removes the adhesive film and damaged components, then addresses any remaining microbial growth through physical agitation and HEPA-contained extraction. We do not sell fogging upsells. Call (361) 326-5060 and we’ll show you what your ducts actually need.
Decades of accumulated debris in shared vertical chases, often including construction dust from renovations, skin cells, and degraded flex duct fragments. The rooftop or closet air handler may be clogged with a solid mat of coastal dust and salt residue. We coordinate with property managers for access and document conditions for maintenance records. If you’re a tenant, we can provide inspection findings to present to your landlord. Call (361) 326-5060 to discuss options.
Yes. Santa Ana winds blow fine desert dust and fire ash into Santa Monica’s open windows and through outdoor air intakes, adding a darker, grittier layer to the usual coastal buildup. After a strong Santa Ana event, we see increased calls for cleaning as homeowners notice visible dust accumulation and respiratory irritation. The debris is often more abrasive than marine-layer grime alone. Call (361) 326-5060 to schedule post-wind-season cleaning.
On a 1930s bungalow off Ocean Park Boulevard near Ashland Avenue, our tech pulled a pair of supply and return registers and found white salt crust blooming across the metal boots and a brittle, cracking flex connector at the air handler. We ran a camera inspection down the short, oddly routed run, set up negative pressure with HEPA filtration at the unit, then worked Rotobrush agitation tools through the branch lines to break the adhesive film loose before it could be captured at the source. The homeowners chose to have the corroded connector and both boots replaced, and the crusty, gritty smell that came back every time the marine layer rolled in stopped after the clean.
