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 Lennox
Most Lennox homeowners pay between $280 and $520 for a full residential air duct cleaning, with older homes needing sealing work running toward the higher end. We dispatch from our Los Angeles office and typically schedule Lennox appointments within three to five business days. Call (469) 972-3151 for a free written estimate.
We’ve worked enough Lennox homes to know the neighborhood’s duct problems aren’t generic. The small post-WWII single-family houses and low-rise apartments built from the late 1940s through the early 1970s carry original duct systems that were never designed for what this community faces now: a constant rain of fine particulate from LAX’s north runway corridors, trapped by the marine layer that sits on this pocket of the South Bay most mornings. Our crews know what that residue looks like, where it hides, and why a surface cleaning alone usually fails here.
Why Kestrel Air Duct Cleaning Is Lennox’s Preferred Air Duct Cleaning Company
Lennox residents call us back because we show up in the window we gave, put the price in writing before touching a vent, and leave the guarantee on paper. Dale Whitmore built this standard into the Kingswell Guarantee when Kestrel joined the family in 2004, and it hasn’t changed.
Our technicians are background-checked, uniformed, and trained on the equipment that matters for this market: Rotobrush rotary brush systems for dislodging bonded residue at the duct wall, Nikro negative-pressure units for source removal, and Abatement Technologies HEPA filtration to keep loosened particles out of your living space during the job. We don’t send a shop vac and a prayer.
Calls are answered by a live person, 24/7. No voicemail tree, no callback roulette. When you’re trying to figure out why your Lennox home’s registers blow dark dust every time the furnace kicks on, you talk to a human who can schedule an inspection or answer what the process costs.
Every job carries the 365-Day Done Right Promise in writing. If the work falls short within that year, we return and make it right at no charge. That’s not a courtesy we extend when we feel like it. It’s documented on every invoice.
Air Duct Inspection in Lennox
Air Duct Inspection in Lennox is where we determine whether your problem is surface contamination, structural failure, or both. We charge $120-$180 for a full camera inspection of the accessible duct network, including the main trunk, branch runs, and return plenum. The inspection typically takes 45 to 90 minutes, and you’ll see what we see on a monitor in real time.
For Lennox homes, this step is non-negotiable. The original galvanized ductwork and early flex installations in this neighborhood have had 50 to 70 years of thermal cycling, vibration, and the unique stress of aviation-particulate loading. We’ve found crushed branch runs behind water heater enclosures, disconnected returns pulling attic air, and main trunks coated in residue that a standard cleaning would simply smear around.
What the Camera Reveals
Our video inspection uses a self-leveling camera head on a flexible rod, pushed through access points we cut or use existing. In Lennox, we’re looking specifically for the sooty, oily film that bonds to metal duct walls, and for structural damage hidden behind decades of remodels. You watch the feed with us. No guessing, no “trust us, it was bad.”
The Written Report
After the inspection, you get a written findings summary with photo stills and a flat-price quote for any recommended work. No per-vent pricing, no add-ons at the door. The price we write is the price you pay.
Residential Air Duct Cleaning in Lennox
Residential Air Duct Cleaning in Lennox runs $280-$520 for a complete supply-and-return system on a typical single-family home, with most falling in the $340-$420 range. Apartment units and smaller homes with limited duct runs sometimes come in lower; homes needing branch-run repair, reconnection, or full sealing work run higher. We establish the exact scope and price before work begins, always in writing.
The process for Lennox homes differs from a standard suburban clean. We start with negative-air extraction, using a Nikro unit to create suction at the air handler while Rotobrush rotary tools agitate the duct walls. This combination strips the bonded aviation residue that a vacuum alone won’t touch. Abatement Technologies HEPA filtration captures particles down to 0.3 microns, keeping your living space clean during the work. Then we camera-verify the results and seal accessible joints with mastic or metal-backed tape, depending on the duct material.
Sealing Original Ductwork
Original Lennox duct systems from the 1950s and 1960s were assembled with snap-lock seams and minimal sealing. The Kingswell Way requires we address this when we find it: leaky joints and register boots let the LAX-corridor plume short-circuit directly into your return path. Sealing adds $180-$340 to a typical job but often matters more than the cleaning itself.
Before-and-After Documentation
We photograph your duct interiors before we start and after we finish. You see the difference. In a neighborhood where bait-and-switch pricing has burned too many homeowners, we put the proof in your hands.
Trusted Brands We Service in Lennox
Kestrel technicians are trained on the equipment that handles Lennox’s specific contamination profile. Our Rotobrush systems break the bond between sooty residue and duct metal. Our Nikro negative-air machines maintain constant suction so dislodged material exits the system rather than resettling. Abatement Technologies HEPA filtration protects your home’s air during the process. For homeowners who want to maintain cleaner air between service visits, we also carry Honeywell, Aprilaire, and Guardsman filtration products. We keep common fittings and sealants stocked for Lennox’s older duct geometries, so most jobs don’t wait on parts.
Common Air Duct Cleaning Problems We See in Lennox Homes
- Sooty, oily residue from LAX corridor exposure. The jet-exhaust plume that settles on Lennox around the clock leaves a combustion signature our crews don’t see a few miles inland. Homeowners often mistake it for ordinary dust until they wipe a register and find black smear instead of gray lint.
- Crushed or disconnected branch runs behind older remodels. Lennox’s small post-WWII homes have been modified repeatedly over 70 years. Water heater relocations, kitchen expansions, and unpermitted additions frequently flatten or sever branch ducts, killing airflow to bedrooms without anyone realizing the cause.
- Unsealed original snap-lock seams. The galvanized ductwork installed in Lennox’s 1950s and 1960s housing stock was never sealed to modern standards. Every gap pulls attic air, wall-cavity dust, and outdoor particulate directly into the system, reloading contamination as fast as cleaning removes it.
- Return plenums pulling garage or crawl-space air. In Lennox’s denser apartment buildings and converted duplexes, we’ve found return pathways compromised by decades of maintenance shortcuts, effectively ventilating the home through the worst possible spaces.
Pricing for Air Duct Cleaning in Lennox, CA
Here’s what Lennox homeowners actually pay:
| Service | Typical Range |
|---|---|
| Air Duct Inspection (camera) | $120 - $180 |
| Residential Duct Cleaning (supply + return, single-family) | $280 - $520 |
| Apartment / small home (limited duct runs) | $220 - $340 |
| Sealing accessible joints and registers | $180 - $340 |
| Branch run reconnection or repair | $140 - $280 per run |
What moves a job toward the higher end: multiple branch runs needing repair, extensive sealing on original 1950s ductwork, or heavy contamination requiring extended agitation time. What doesn’t affect price: number of vents. We quote per system, not per register, because per-vent pricing is the bait-and-switch industry’s favorite trick. You’ll know your exact cost before we start. Call (469) 972-3151 for a free written estimate.

FAQs About Air Duct Cleaning in Lennox
Your dark, oily residue is aviation combustion particulate from LAX’s north runway corridors, trapped by Lennox’s persistent marine layer. This sooty signature bonds to duct walls differently than ordinary household lint and dander, which is why standard cleaning methods often fail here and why we use rotary brush agitation with negative-air extraction specifically for this contamination type. Call (469) 972-3151 and we’ll camera-inspect to confirm what you’re dealing with.
Yes, regularly. Seventy years of remodels, water heater relocations, and unpermitted additions in Lennox’s dense housing stock have left many branch runs flattened, severed, or buried behind new walls. Our camera inspection finds these failures before we quote, so you’re not paying to clean ducts that aren’t delivering air to your rooms. The fix typically runs $140-$280 per run, quoted in writing before any repair work.
Cleaning alone often fails in Lennox because original 1950s and 1960s ductwork has unsealed snap-lock seams and deteriorated register boots. Without sealing, the LAX-corridor particulate reloads your system every season through the same gaps. We evaluate this during inspection and quote sealing separately, typically $180-$340, so you can decide with full information. Call (469) 972-3151 for an inspection and written options.
We contain the work zone using Abatement Technologies HEPA filtration and negative-air isolation from our Nikro units. The system maintains suction at the air handler while we agitate ducts, pulling loosened particles directly into filtered collection rather than letting them escape into your living space. This isn’t standard on every contractor’s truck; it’s part of how we handle Lennox’s specific contamination profile.
We check blower wheel buildup, motor amp draw, and evaporator coil condition, because Lennox’s fine particulate loading accelerates fouling on all three. A dirty blower wheel alone can drop system efficiency 15% and recirculate contamination even after ducts are clean. Our inspection includes these components and documents findings with photos. Call (469) 972-3151 to schedule.
