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 Lennox
Air duct cleaning in Lennox, CA typically runs $280 – $520 for a full residential system and $450 – $950 for commercial work, with most jobs scheduled within a few days and completed in three to five hours. We’re familiar with the tight lots along Lennox Boulevard and the pre-1978 bungalows near the airport corridor, and our crews know that Lennox homes need a different approach than standard suburban HVAC jobs. Dispatch and scheduling are coordinated from our Los Angeles office, but the technicians who roll to Lennox are local to the South Bay and carry the tools for short wall-vent runs, not just full central systems. Call (361) 326-5060 for a free written estimate before any work starts.
Why Hollis Air Duct Cleaning Is Lennox’s Preferred Air Duct Cleaning Company
We’ve been serving Lennox since our founding in 2004 as part of the Garrison Partners family, and our reputation here is built on showing up when we said we would and leaving the price where we wrote it down. Lennox homeowners have told us the same story for years: a crew quotes low over the phone, then the invoice jumps once the van is in the driveway. That doesn’t happen with Hollis. The price is written before we touch anything, and it doesn’t move at the door.
Our technicians are background-checked and uniformed, and they arrive inside the quoted window. They know Lennox’s housing stock – the slab foundations, the wall furnaces, the original 1950s metal duct runs behind stucco – because they’ve cleaned hundreds of them. Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No callback queues.
Every job carries our 365-Day Done Right Promise in writing. If the work fails within a year, we come back and make it right at no charge, including a free second visit. That’s The Garrison Standard, and it’s how we operate in Lennox.
Residential Air Duct Cleaning in Lennox
Residential Air Duct Cleaning in Lennox means something different than in a newer suburb with full central HVAC. Most Lennox homes are 1940s – 1960s single-story stucco bungalows on slab foundations with wall furnaces, window units, or through-wall AC. The “ducts” are often short original metal runs feeding wall registers or floor vents, sometimes with retrofitted flex sections behind the furnace. Our crews clean these with rotary brush agitation under negative pressure, using HEPA filtration so the sticky aviation particulate we dislodge doesn’t resettle in your living space. A typical residential job in Lennox runs $280 – $520 depending on run count, accessibility, and whether we find disconnected or crushed sections that need reconnection and sealing.
Wall-Vent and Floor-Register Focus
Because Lennox homes rarely have extensive attic ductwork, we spend most of our time at the wall and floor registers. The Rotobrush system scrubs the short metal runs while our Nikro negative-air machine pulls debris through HEPA filtration. This matters in Lennox because the black film coating those registers is aviation soot, not ordinary dust – it smears and resettles if you just blow compressed air through.
Sealing and Reconnection Work
Behind many Lennox wall furnaces, we find flex runs that have pulled loose or been crushed against slab foundations. We reconnect these and seal with mastic, then verify airflow at each register. This sealing work is often the real fix, and we price it in writing before we start so you’re not deciding under pressure.
Commercial Air Duct Cleaning in Lennox
Commercial Air Duct Cleaning in Lennox covers the small retail spaces, restaurants, and light industrial buildings along Century Boulevard and adjacent to the airport corridor. These buildings often have rooftop package units with metal duct runs that have accumulated decades of jet exhaust particulate and marine-layer moisture. We use negative-air methods with portable HEPA containment, sized to work around operating businesses. A typical commercial job in Lennox runs $450 – $950 depending on system size, access difficulty, and contamination level. We schedule after-hours when needed and provide before-and-after photos of your own ducts.
Restaurant and Food-Service Systems
Lennox restaurants near the airport deal with grease-laden kitchen exhaust plus aviation soot drawn through makeup air units. We clean supply and return runs separately, with source removal for grease buildup and HEPA containment for particulate. The work is priced by system, not by vent, so your quote doesn’t shift once we’re on site.
Retail and Office Package Units
Rooftop units serving Lennox strip retail often have short, accessible duct runs that we can clean and video-inspect efficiently. We document condition with camera footage and flag any corrosion or separation caused by salt-air exposure from the nearby coast.
Trusted Brands We Service in Lennox
Our equipment roster includes Rotobrush rotary brush systems for agitation cleaning, Nikro negative-air machines for source removal with HEPA containment, and filtration products from Honeywell, Aprilaire, and Guardsman. We don’t show up with hardware-store vacuums and compressed-air wands. For Lennox’s sticky aviation soot, the combination of mechanical agitation and controlled negative pressure is what actually removes the contaminant rather than redistributing it. We stock common fittings and flex duct for the reconnection and sealing work these older bungalows often need, so most jobs finish in one visit without waiting on parts.
Common Air Duct Cleaning Problems We See in Lennox Homes
- Sticky black film in wall registers. That greasy, graphite-like coating our techs find on Lennox registers is kerosene exhaust fallout from LAX operations, bound in place by marine-layer humidity. Ordinary dusting or compressed-air blowing just smears it deeper into the duct.
- Disconnected runs behind wall furnaces. On slab foundations with no basement access, flex duct retrofits often pull loose from the furnace plenum or get crushed against the slab. We find these with camera inspection and reconnect them with mastic seals.
- Crushed flex sections in short runs. Lennox’s original 1950s metal duct was sometimes extended with flex that has collapsed from age or improper support, blocking airflow and creating dead zones where moisture and soot accumulate.
- Improper cleaning methods that redistribute soot. Crews who blow compressed air or run a brush without negative pressure and HEPA filtration knock the sticky aviation particulate loose, where it coats the blower motor and blows back into the room through the next cycle.
Pricing for Air Duct Cleaning in Lennox, CA
A typical residential air duct cleaning in Lennox runs $280 – $520 for a full system with up to 8 – 10 runs, including wall vents, floor registers, and the short metal or flex runs behind them. Commercial systems start around $450 and range to $950 for larger rooftop units or multi-zone buildings. What moves the price: number of runs, accessibility (crawl space vs. open attic), whether we find disconnected or crushed sections needing reconnection and sealing, and the level of contamination – that sticky aviation soot takes more contact time than ordinary dust.
We give one flat price per system, agreed in writing before work starts. No per-vent pricing. No add-ons at the door. You’ll see before-and-after photos of your own ducts, and if the work fails within a year, our 365-Day Done Right Promise covers a free return visit.

FAQs About Air Duct Cleaning in Lennox
That film is sticky kerosene exhaust fallout from LAX flight operations, held in place by Lennox’s marine-layer humidity – not ordinary household dust. It collects in wall and floor registers because most Lennox homes have open windows and attic vents that feed outside air into short duct runs year-round. Call (361) 326-5060 and we’ll inspect the buildup and quote removal with the right equipment.
Yes, if you have wall furnaces, through-wall units, or any duct runs feeding registers. Those short runs still accumulate the aviation soot and moisture-driven dust we find throughout Lennox, and they still blow into your living space when the fan cycles. We clean wall-vent and floor-register systems, not just full central HVAC. Call (361) 326-5060 to discuss your specific setup.
Lennox homes typically need cleaning every 2 – 3 years, more often than inland desert cities where drier air and less jet particulate mean 4 – 5 year intervals. The combination of LAX exhaust fallout and coastal moisture accelerates buildup in your ducts. Call (361) 326-5060 and we’ll assess your current contamination level.
Negative pressure means our Nikro machine pulls a vacuum on your duct system while we agitate the walls with a rotary brush, so dislodged debris is captured through HEPA filtration instead of escaping into your home. On a Lennox job, this matters enormously because the sticky aviation soot would otherwise smear and resettle on furniture and the blower motor. Call (361) 326-5060 for a free estimate.
In most cases, yes. The original metal runs in Lennox bungalows are accessed through existing wall registers and floor vents, and we use flexible rotary tools that navigate short runs without cutting drywall. If we find a disconnected or crushed section behind a wall furnace, we can usually reach it through the furnace cavity or a small access panel. Call (361) 326-5060 and we’ll explain what your specific layout allows.
