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 $350-$650 for a full residential system, with most jobs completed in a single visit. We’re Morton’s Air Duct Cleaning, and we’ve been sending crews to Lennox since 2005, dispatching from our Los Angeles office to homes near Century Boulevard, the blocks around Lennox Park, and the stucco duplexes lining Prairie Avenue. If you’re noticing dark debris around your registers, smelling mustiness when the HVAC kicks on, or simply can’t remember the last time your ducts were opened up, call us at (323) 918-4345. We’ll give you a written price before any work starts, and we’ll show you exactly what we found with a camera.
Why Morton’s Air Duct Cleaning Is Lennox’s Preferred Air Duct Cleaning Company
Lennox homeowners know their ducts aren’t like anyone else’s. The marine layer rolls in off the Pacific most nights, and the LAX flight paths overhead drop ultrafine particulate into attic and crawl-space ductwork that neighbors in Hawthorne or Gardena simply don’t face at the same concentration. We’ve learned to account for both.
Our technicians arrive in uniform with background checks already completed. They lay drop cloths at the door and wear shoe covers inside, because we’ve cleaned enough homes near Lennox Park to know that toddlers nap in the afternoon and dogs sleep in hallways. We work to the Cedarwell C.A.R.E. values, which means quieter tool settings during nap hours and pet-safe product choices wherever they’re available. Every job carries our 365-Day Done Right Promise, stamped on the paperwork, not offered only if you ask. And before we leave, we send you a photo of the clean-up so you can see your floors, furniture, and registers left better than we found them.

Ductwork Cleaning in Lennox
Ductwork Cleaning in Lennox addresses a contamination profile most generic advice misses entirely. The combination of jet-combustion ultrafine particles from LAX operations and the persistent coastal moisture that settles into these 1950s-1960s stucco homes creates dark, damp, sooty buildup inside supply and return runs. A proper clean here isn’t vacuum-only; it’s source removal using agitation tools, negative pressure with HEPA filtration, and careful inspection of the aging flex-duct seams common to this housing stock.
Most Lennox homeowners schedule Ductwork Cleaning when they notice visible dark debris around registers, musty odors when the system cycles, or increased allergy symptoms among family members. In this market, a typical full residential Ductwork Cleaning runs $350-$650 depending on system size and accessibility, with duplexes and small apartment buildings on the lower end and larger homes with multiple zones toward the higher range.
What Genuine Source Removal Looks Like
We don’t fog and call it done. Our crews use Rotobrush agitation systems and Nikro negative-pressure HEPA collectors to physically break loose and extract debris from the duct walls. In Lennox, that debris is often bonded to damp flex-duct interior surfaces, so agitation matters more than suction alone. We also pull the blower motor and clean the air handler cabinet, because the lint and particulate pathway through that assembly is where much of the real contamination hides.
Protecting Your Home During the Work
Before we touch a tool, we cover floors with drop cloths and protect furniture near access points. Shoe covers stay on until we exit. For families with pets, we seal work areas to contain dust and use the quietest effective settings on our equipment. The written price we agreed to before starting is the price on the invoice, period.
Air Duct Inspection in Lennox
Air Duct Inspection in Lennox should happen before any cleaning quote is finalized, because the housing stock here carries specific risks that change how we approach the job. Many of these small post-war homes and duplexes still contain original or early-replacement duct systems with asbestos-containing duct wrap from the 1950s-1970s, or flex-duct retrofits with seams that have degraded and leak into wall cavities. An inspection with a borescope camera lets us see what we’re dealing with before we disturb anything.
We recommend an Air Duct Inspection for Lennox homeowners buying an older property, noticing uneven airflow between rooms, or preparing for any duct cleaning after a gap of several years. A standalone inspection runs $150-$250 in this market, though we credit that toward your cleaning if you proceed with us. The inspection typically takes 45-60 minutes and covers the full supply and return pathways, the air handler, and accessible duct wrap condition.
Camera Findings That Change the Plan
On a 1950s stucco duplex off the 10400 block near Century Boulevard, our tech ran a camera inspection down the return and found flex-duct retrofitted years earlier with seams leaking into the wall cavity, so the register pulled sooty black debris less than two years after the homeowner’s last cleaning. We set up negative pressure with HEPA filtration at the air handler, used agitation tools on the supply and return ducts, and pulled the blower motor to clear the buildup before sealing the leaks. The debris volume was roughly double what we see on a comparable-size home a few miles inland.
When Duct Wrap Needs Professional Evaluation
If our camera reveals aging duct wrap that may contain asbestos, we stop and recommend a certified asbestos inspector before proceeding. We don’t disturb suspect material. This is rare but real in Lennox’s housing stock, and it’s why we inspect first.
Trusted Brands We Service in Lennox
Our crews arrive with professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, not rental-shop vacuums with duct attachments. Rotobrush brush-and-vac systems handle the agitation and extraction inside damp Lennox duct runs where sooty particulate has bonded to flex-duct walls. Nikro negative-pressure HEPA collectors maintain containment during the work, critical in these small, densely packed homes where living space sits close to the HVAC system. Abatement Technologies filtration protects the home’s air during the process. We stock common parts and accessories locally, so if an inspection reveals a separated duct seam or failed register boot near Lennox Park or along Prairie Avenue, we can often address it during the same visit rather than scheduling a return trip.
Common Air Duct Cleaning Problems We See in Lennox Homes
- Damp, sooty buildup instead of dry dust. The marine layer introduces nightly moisture while LAX flight paths deposit ultrafine jet-combustion particles. The result is dark, almost greasy deposits that standard vacuum-only cleaning won’t remove. Agitation and HEPA extraction are essential here.
- Leaky flex-duct seams pulling debris from wall cavities. Many Lennox retrofits used flex-duct with inadequate sealing. Our cameras regularly find return ducts drawing unfiltered air, and sooty debris, from attics and crawl spaces through gaps at connections.
- Fogging “sanitiser” treatments sold as cleaning. A mist coating doesn’t remove anything. In Lennox’s moist duct environment, it can actually seal microbial growth against the duct wall while leaving jet-exhaust particulate untouched. We don’t offer fogging as a substitute for physical source removal.
- Ignored blower motors and air handler cabinets. The pathway from return to supply runs through this assembly. If it’s caked with lint and particulate, clean ducts just get re-contaminated. We pull and clean the blower on every full system job.
Pricing for Air Duct Cleaning in Lennox, CA
Most full residential air duct cleaning jobs in Lennox fall between $350 and $650. A small single-system duplex or apartment near Century Boulevard typically runs $350-$450. Larger homes with multiple zones, complex access, or significant contamination from long-deferred maintenance can reach $550-$650. Commercial systems and multi-unit buildings are quoted individually after inspection.
What moves the number: system size and zone count, accessibility of the air handler and ductwork, the degree of buildup we’re extracting, and whether we find separated seams or failed components that need repair during the visit. We don’t price per vent, and we don’t bait with a low teaser that balloons once we’re in your driveway. One flat price per system, agreed in writing before any work starts. Every time.
Call (323) 918-4345 for a free estimate. We’ll ask about your home’s size, age, and what you’re noticing, then give you an honest range with no pressure to book.

FAQs About Air Duct Cleaning in Lennox
Lennox sits directly beneath active LAX flight paths, and the jet-combustion ultrafine particles that settle here are documented at among the highest concentrations in LA County. Combined with the nightly marine layer that introduces consistent moisture, Lennox ducts accumulate dark, damp, sooty buildup rather than the dry dust typical inland. Call (323) 918-4345 for an inspection if you’re seeing faster re-contamination than expected.
No. Fogging coats surfaces without removing source contamination. In Lennox’s moist duct environment, it can seal existing microbial growth against the duct wall while leaving jet-exhaust particulate and actual mold colonies intact. Physical agitation, HEPA extraction, and drying are what’s needed. We don’t sell fogging as a cleaning substitute.
We inspect with a camera first, then set up negative pressure HEPA containment at the air handler. Agitation tools break loose bonded debris from duct walls, the vacuum system extracts it, and we pull and clean the blower motor and cabinet. Finally, we seal any accessible leaks and send you photos of the completed work. The written price we gave you beforehand is the price you pay.
It can be. Some original duct wrap in this era’s housing stock contained asbestos. We camera-inspect first, and if we see suspect material, we stop and recommend certified asbestos evaluation before disturbing anything. We never proceed with cleaning when asbestos-containing material might be present.
Most Lennox homeowners benefit from inspection every 2-3 years and full cleaning every 3-5 years, though homes immediately north of Century Boulevard under the heaviest flight paths sometimes need attention sooner. The dark, sooty debris our crews pull from those blocks is visibly distinct from inland dust. Call (323) 918-4345 and we’ll help you set a schedule based on your specific location and system condition.
