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 Westminster
Air duct cleaning in Westminster, CA typically runs $350 – $650 for a full residential system and $800 – $2,400 for commercial jobs, with most homes completed in a single visit. Our crews serve Westminster from our Los Angeles dispatch office, carrying Rotobrush rotary systems and Nikro negative-air machines through neighborhoods from Little Saigon to the Bolsa Avenue corridor. We know the parking constraints around Westminster Mall, the tight lot lines on 1970s tracts off Brookhurst Street, and the shared attic spaces that let cooking odors migrate between units. Call (361) 326-5060 for a written estimate before any work starts.
Why Hollis Air Duct Cleaning Is Westminster’s Preferred Air Duct Cleaning Company
We’ve been part of the Garrison Partners family since 2004, and our Air Duct Cleaning team has built a reputation in Westminster by solving problems that generic crews miss. Homeowners here aren’t dealing with ordinary dust; they’re fighting grease films from daily fish sauce and charcoal cooking that standard vacuums can’t touch. Our 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.
Our technicians are background-checked and uniformed, and they arrive inside the quoted window. The price is written down before any equipment enters your home, and it does not move at the door. Phones are answered by a live person 24 hours a day, seven days a week, so you’re not waiting through voicemail loops when you need to schedule around Westminster’s busy commercial corridors.
We know Westminster’s housing stock: single-story ranches off Magnolia Street, two-story tracts near Westminster High School, and the dense apartment clusters along Beach Boulevard. That local knowledge means we bring the right equipment for your specific duct type, not a one-size-fits-all approach.
Commercial Air Duct Cleaning in Westminster
Commercial Air Duct Cleaning in Westminster addresses a unique challenge: many businesses in Little Saigon operate out of converted residential spaces with undersized ductwork never designed for restaurant-grade exhaust loads. These systems clog with grease and odor-causing residues far faster than standard commercial installations, and the shared building systems common along Bolsa Avenue and Westminster Boulevard mean one unit’s problem becomes every unit’s problem. A typical commercial duct cleaning in Westminster runs $800 – $2,400 depending on system size and contamination level.
Grease Removal in Mixed-Use Buildings
Standard vacuuming won’t strip the sticky film that builds up from years of fish sauce, frying, and charcoal grilling. Our crews use degreasing agents followed by rotary brush agitation to break that bond, then capture the loosened material with negative-air HEPA extraction. We document the before condition with video inspection so you see exactly what was in your ducts.
Scheduling Around Operating Hours
Westminster’s restaurants and catering kitchens can’t shut down during lunch or dinner rushes. We schedule commercial work during closed hours or prep windows, and our written arrival window means your staff isn’t waiting on a crew that shows up whenever. The price is fixed before we start, so there’s no renegotiation while your kitchen is offline.
Air Duct Cleaning Services in Westminster
Air Duct Cleaning Services in Westminster cover the full range of residential and light commercial systems found in this city’s 1950s – 1980s housing stock. Most Westminster homes have never had their ducts properly sealed or cleaned; original galvanized steel or early flex duct systems accumulate decades of dust, pollen, and the distinctive grease residue from heavy year-round cooking. A typical residential full-system cleaning in Westminster costs $350 – $650, with supply-only or return-only runs at $180 – $340. Video inspection adds $120 – $200 when you want visual confirmation of the duct condition.
Full System Cleaning with Leak Sealing
In Westminster’s dense tract neighborhoods, unsealed duct leaks don’t just waste energy; they transfer cooking odors and loosened debris into adjacent units through common attic chases. We seal accessible leaks with mastic before cleaning, so contaminants exit through our vacuum rather than your neighbor’s bedroom vent.

Dryer Vent Cleaning in Shared Stacks
Many Westminster apartments and condos share vertical dryer vent stacks that run through multiple floors. Clearing only the trap ignores the lint pathway inside the vertical run, where buildup is the leading factor in dryer fires. We clean the full stack length where accessible, not just the easy-to-reach portions.

Trusted Brands We Service in Westminster
Our Westminster crews carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, plus filtration products from Honeywell, Aprilaire, and Guardsman. These aren’t hardware-store tools; they’re the same rotary brush systems and negative-air machines used in commercial hospital and school cleanings. We stock common filtration components locally, so if your Westminster home needs a Honeywell media upgrade or an Aprilaire filter replacement during the same visit, we can handle it without a return trip. That matters in a city where parking is tight and scheduling a second appointment costs you another morning off work.
Common Air Duct Cleaning Problems We See in Westminster Homes
- Grease-coated horizontal runs near kitchen exhausts. Technicians vacuum the visible registers but skip the sticky film inside horizontal duct runs, leaving a rancid odor source that keeps recirculating through shared attic spaces. We flag these runs with video inspection before quoting, so the degreasing step is built into the price from the start.
- Unsealed leaks in common attic chases. In dense tract-home clusters, crews don’t seal duct leaks before cleaning, so loosened debris and cooking odors drift into adjacent units instead of being captured by negative pressure. We seal accessible joints with mastic as part of our standard process.
- Shared dryer vent stacks cleared only at the trap. Apartment and condo buildings throughout Westminster have vertical dryer runs that accumulate lint far above the ground-floor trap. Ignoring that pathway leaves a fire hazard intact and keeps drying times long.
- Santa Ana wind infiltration through return systems. Westminster’s occasional Santa Ana events pull fine dust and wildfire ash through exterior vents and into return-air ducts, loading filters and duct walls with material that standard household vacuums can’t remove. We see this especially in homes near the 22 freeway corridor.

FAQs About Air Duct Cleaning in Westminster
Westminster’s combination of heavy year-round cooking in Little Saigon, shared attic spaces in dense tracts, and Santa Ana wind infiltration loads ducts with grease, odor particles, and fine dust continuously rather than seasonally. Most homes here benefit from cleaning every 2 – 3 years instead of the 4 – 5 year interval typical in less dense, lighter-use markets. Call (361) 326-5060 and we’ll assess your specific system.
Yes, and shared systems actually require more careful technique, not less. We coordinate with property management where needed, seal our work area to prevent cross-contamination, and use negative-air containment so loosened debris exits through our vacuum rather than neighboring units. The 365-Day Done Right Promise applies to multi-family jobs the same as single-family. Written price before work starts, always.
We apply a commercial degreasing agent to break the bond, then use a Rotobrush rotary brush to agitate the film loose, and finally capture everything with a Nikro HEPA vacuum under negative pressure. Standard vacuuming alone won’t remove grease; it just moves it around. We got a call from a two-story tract home on Bolsa Avenue where the family had been running a home catering kitchen for years; their return ducts were coated in sticky grease that had migrated toward the air handler. Using a Rotobrush rotary brush and a degreasing agent, we removed the film, then ran a Nikro HEPA vacuum under negative pressure to pull residual odor-causing particles out of the supply and return ducts. The homeowner said the fish sauce smell that used to linger in the upstairs bedrooms was gone within a day.
Westminster’s mild climate means HVAC systems run year-round for both cooling and heating, so accumulation is continuous rather than concentrated in one season. The coastal humidity is moderate, but the Santa Ana winds bring fine dust and occasional wildfire ash that loads return-air systems fast. Most Westminster homeowners we serve schedule cleaning every 2 – 3 years, with annual filter changes and dryer vent checks in between.
Shared vertical stacks are common in Westminster’s apartment and condo buildings, and they’re frequently cleaned only at the ground-floor trap while lint continues building in the vertical run. That buildup restricts airflow, extends drying times, and creates a fire hazard. We clean the full accessible length of shared stacks and provide written documentation of what was removed. The 365-Day Done Right Promise covers our dryer vent work too: if airflow isn’t improved, we return at no charge.
