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.

AfterFast, Reliable Air Duct Cleaning Across La Mirada
Air duct cleaning in La Mirada typically runs $350 – $650 for a full residential system and is usually completed in one visit, with our Air Duct Cleaning in La Mirada crews dispatching from the Los Angeles office to reach most neighborhoods inside the same day we schedule. We’ve been working in the tree-lined streets off Alicante Road, the tracts near La Mirada Boulevard, and the original 1950s ranches around Imperial Highway long enough to know what these houses hide in their walls. If your home was built during the Eisenhower or Kennedy administrations, odds are the ductwork behind your vents was designed for a gravity furnace, retrofitted for central air, and has been accumulating debris for decades. Call (361) 326-5060 for a free estimate and we’ll show you exactly what’s in there before we touch a thing.
Why Hollis Air Duct Cleaning Is La Mirada’s Preferred Air Duct Cleaning Company
La Mirada homeowners don’t call us because we’re the cheapest bid on the block. They call because they’ve already lived through the alternative: a coupon special that ballooned at the door, a crew that tracked dust through the hallway, or vents that looked clean but still blew weak, warm air into the back bedroom. Hollis Air Duct Cleaning, founded in 2004 as part of the Garrison Partners family, operates on The Garrison Standard: written price before work starts, background-checked uniformed technicians, and a 365-Day Done Right Promise that covers every job in writing. If the work fails within a year, we come back and make it right at no charge, including a free second visit. Our phones are answered by a live person 24 hours a day, 7 days a week, and our Air Duct Cleaning crews arrive inside the quoted window with professional-grade equipment from Rotobrush, Nikro, and filtration brands including Honeywell and Aprilaire.
Air Duct Inspection in La Mirada
Air Duct Inspection in La Mirada starts with a camera run through your supply and return lines, because in this city the problem is rarely just dust. Most La Mirada homes were built in the 1950s – 60s as slab-on-grade, single-story tracts, so the original heating systems used under-slab return ducts and undersized 4 – 6 inch round pipes that are still in service behind retrofitted central A/C. Because lot lines are close and roofs are low-pitch or flat, our crews regularly find flex runs crushed in the attic or disconnected at the plenum – failures that a standard vacuum-only clean will not correct. A full inspection with video documentation runs $150 – $250 in La Mirada, and we apply that fee toward any cleaning or repair work you approve.
What We Document
Our technicians record every foot of accessible ductwork, noting debris depth, insulation condition, and mechanical integrity. You’ll see the footage yourself, and we’ll mark timestamps where the original asbestos-era wrapping shows wear or where a run has torn free from its boot.
When to Schedule
Book an inspection before you buy a home near La Mirada Boulevard, if you’ve never had your ducts opened since moving in, or after any rodent activity in the attic. The camera doesn’t guess; it shows you whether you’re looking at a cleaning job or a repair.
Residential Air Duct Cleaning in La Mirada
Residential Air Duct Cleaning in La Mirada means source removal of accumulated debris from your entire forced-air system, not just vacuuming the vent covers. We were called to a 1958 ranch on Alicante Road where the homeowner said two front bedrooms never got cold air; camera inspection showed the original 5-inch run had torn loose from the plenum boot in the low attic and was pulling attic dust instead of conditioned air. Using agitation tools and HEPA filtration under negative pressure, we source-removed decades of debris from the supply and return ducts, reconnected the run with new flex, and sealed the plenum – the bedrooms now hold temperature with the same equipment. A typical whole-system residential cleaning in La Mirada runs $350 – $650 depending on system size, accessibility, and whether we find disconnected runs that need reconnection and sealing.
The Rotary Brush Method
Our Rotobrush system sends a rotating brush and simultaneous vacuum through each supply and return line, physically dislodging debris rather than blowing it deeper into the system. In La Mirada’s narrow 4 – 6 inch original ducts, this matters more than in newer homes with 8-inch mains; the smaller diameter means buildup restricts airflow faster and aggressive compressed-air methods can damage aged flex.
Negative-Air Containment
We seal your HVAC unit and run a Nikro negative-air machine during cleaning, creating suction that prevents debris from escaping into your living space. This is especially important in La Mirada homes where the furnace closet is often too small for modern equipment and sits adjacent to hallways or bedrooms with no door to close.
Trusted Brands We Service in La Mirada
Hollis stocks filtration and replacement components from Honeywell, Aprilaire, and Abatement Technologies, the same brands commercial crews specify for hospitals and schools. For La Mirada’s older systems, we carry adapters that let modern media filters fit original 1950s return grilles without visible exterior modification, a detail that matters in a city where neighbors notice and code enforcement follows. If your inspection reveals a crushed flex run or failed plenum seal, we have the Nikro negative-air equipment and the right fittings to restore airflow without waiting on a parts order. Our technicians explain what each component does and why we’re using it before they open a single vent.
Common Air Duct Cleaning Problems We See in La Mirada Homes
- Cracked under-slab returns pulling soil and moisture. The original slab-on-grade construction in La Mirada neighborhoods like those off Imperial Highway used concrete-encased return channels that crack over decades. We find homeowners running dehumidifiers constantly without realizing the source is a broken return duct pulling damp soil air straight into the handler.
- Crushed or disconnected flex in low attics. La Mirada’s low-pitch and flat roofs leave technicians crawling through 24-inch clearances where original 4 – 6 inch flex duct has been kinked by storage boxes, compressed by insulation, or torn completely free at the plenum boot. Vacuuming a disconnected line cleans nothing; reconnection and sealing is the actual fix.
- Asbestos-era insulation disturbed by aggressive methods. The 1950s – 60s trunk lines in La Mirada still carry original wrapped insulation that can release fibers if scraped or abraded. Our crews inspect before agitating, and if we find friable material, we stop and discuss containment options rather than proceeding blindly.
- Furnace closets too small for proper access. Many La Mirada homes have original closets designed for gravity furnaces, now crammed with modern air handlers and coils. Re-routing ducts through adjacent walls is common, and because any new exterior vent is visible to neighbors, we plan routing that avoids permit triggers and maintains your home’s appearance.
Pricing for Air Duct Cleaning in La Mirada, CA
Whole-system residential duct cleaning in La Mirada runs $350 – $650 for a typical single-story home with 8 – 12 vents. Commercial systems start around $800 and scale with square footage and HVAC unit count. Inspection with video documentation is $150 – $250, applied to cleaning if you proceed. Duct Sealing in La Mirada with mastic and mechanical fasteners adds $200 – $400 depending on linear feet of accessible trunk line. What moves the price: attic accessibility (low-pitch roofs take longer), number of disconnected runs requiring reconnection, and whether we find asbestos-era insulation that needs careful handling. We write the full price down before any work starts, and that number does not move at the door. No per-vent add-ons, no equipment fees that appear after we’re inside.

FAQs About Air Duct Cleaning in La Mirada
We can clean most original La Mirada ductwork safely if the asbestos-era insulation is intact and non-friable; our inspection identifies the condition before we touch anything. If the wrapping is damaged or crumbling, we stop and discuss containment or referral to a licensed abatement contractor. Call (361) 326-5060 and we’ll camera-inspect first so you know exactly what you’re dealing with before committing to any work.
The under-slab return duct serving that zone is likely cracked or disconnected, pulling soil air instead of returning conditioned air from the room, which starves the supply side of pressure. A standard vacuum-only cleaning won’t find this; our camera inspection will, and reconnection or sealing of the return path is usually the fix, not another cleaning. Call (361) 326-5060 for a diagnostic that targets the actual failure.
La Mirada’s fall Santa Ana winds push fine dust and pollen through attic vents and open windows, and the mild year-round temperatures mean most homeowners run heating and cooling both, cycling debris through ductwork more frequently than in single-season climates. Every 3 – 5 years is reasonable for most La Mirada homes, sooner if you have pets, recent remodeling, or visible dust at registers.
Standard interior duct cleaning and sealing requires no permit; only new exterior vents, visible routing changes, or structural modifications trigger La Mirada’s code enforcement attention. We plan our work to avoid visible alterations, and if your system needs re-routing that would show from the street, we discuss permit requirements and options before proceeding.
We seal the air handler and run Nikro negative-air machines that create suction at the point of disturbance, capturing debris before it enters your living space. Technicians also isolate work zones with zip barriers and run HEPA air scrubbers in occupied rooms. The Garrison Code requires us to leave the site clean, which in La Mirada’s tight, owner-occupied homes means we protect your floors and furniture like we would our own.
