Fast, Reliable Air Duct Cleaning Across Lennox
Air duct cleaning in Lennox typically costs between $350 and $700 for a standard single-family home, and most jobs wrap up in four to six hours. We also offer Dryer Vent Cleaning in Lennox for homeowners who want their full ventilation system serviced at the same visit. That’s the honest range for our market, where the housing stock runs older and the ductwork often carries decades of buildup. The real question most Lennox homeowners have isn’t whether duct cleaning works. It’s whether the company doing it will actually do what they said. We answer that with a written price before any work starts, before-and-after photos of your own ducts, and a full year to tell us if something wasn’t done right.

We know Lennox. Not from a mapping app, but from hundreds of crawlspace entries beneath post-war stucco homes off Inglewood Avenue, Hawthorne Boulevard, and the side streets that run through this community. The houses here have a specific character: single-story, wood-frame, built between 1940 and 1965, with forced-air systems running through unconditioned attics and tight crawlspaces. That’s our everyday terrain.
Key takeaways:
- Whole-home air duct cleaning in Lennox runs $350 – $700 for a typical three-bedroom house.
- Older Lennox homes often have original galvanized ductwork that needs more than a vacuum pass; sealing and reconnection work is common.
- Every job includes a written price before work begins, photo proof, and a 365-day guarantee.
- Our crews serve Lennox daily, with scheduling coordinated from the brand’s Los Angeles office.
Why Cardinal Air Duct Torrance Is Lennox’s Preferred Air Duct Cleaning Company
Lennox isn’t Torrance, and it isn’t Inglewood. The housing stock here is older, denser, and far more likely to have original duct runs that were installed when Eisenhower was president. Our technicians understand what that means in practice: galvanized metal that has corroded from decades of marine layer moisture, flex runs that rodents have chewed through in crawlspaces, and return ducts that have disconnected entirely, quietly pulling attic insulation into the blower motor for years without anyone noticing.
We’re part of the Relay Home Co. family, founded in 2005, and every location operates under The Relay Visibility Guarantee. That’s not marketing language. It means you get a live trackable arrival time on your phone, before-and-after photo documentation of every register and the main trunk line, and a digital invoice you can pay from a link. Background-checked, uniformed technicians arrive with professional-grade equipment: Rotobrush rotary brush systems, Nikro HEPA vacuums, and Abatement Technologies containment units. You’ll know the technician’s name before they knock. You’ll know the price before they uncoil the first hose.
Omar Haddad leads our team, and the standard he set is simple: if it’s not done right within 365 days, we return and correct it at no charge. That’s the Air Duct Cleaning standard every Lennox customer gets, on every job, without exception.
Styles & brands we work with
Residential Air Duct Cleaning in Lennox
Residential Air Duct Cleaning in Lennox is a different animal than duct cleaning in a newer planned community. The task here is remediation, not maintenance. We’re removing decades of accumulated dust, soot, pet dander, and degraded insulation from ductwork that has often been in place for fifty or sixty years. Most Lennox homes have central forced-air heating with ducts running through unconditioned attics and crawlspaces, which means everything from blown-in insulation to eucalyptus debris finds its way into the system over time.
What does it cost? For a standard three-bedroom Lennox home with roughly ten to fourteen registers, plan on $350 to $700 for a full source-removal cleaning. That price covers the supply and return sides, the blower compartment, and the main trunk line. If we find a disconnected return duct or crushed flex run, which happens on a regular basis here, we’ll show you photos and give you a separate written quote for the repair. You approve it before we touch it. No surprises at the door.
Full System Cleaning
This is what most Lennox homeowners actually need. We clean the supply ducts, return ducts, plenum, blower motor housing, and coil. We use negative-pressure extraction, which means the loosened debris goes straight into the HEPA-filtered vacuum, never back into your living room. The end result is a system that moves air the way it was designed to, without carrying fifty years of dust along with it.
Supply and Return Duct Cleaning
Supply ducts push conditioned air into rooms; return ducts pull air back to the blower. In Lennox homes, returns are often the bigger problem. When a return duct disconnects in a crawlspace, it stops pulling air from the living space and starts pulling air, insulation, and rodent debris from under the house. We inspect both sides on every job, reconnect what has come apart, and seal what has leaked.
Commercial Air Duct Cleaning in Lennox
Commercial Air Duct Cleaning in Lennox covers the duplexes, small apartment buildings, and storefronts that make up much of this community’s built environment. Landlords and property managers here face a specific challenge: tenant turnover, years of deferred maintenance, and duct systems that were never designed for modern filter standards. A four-unit apartment building off Lennox Boulevard often has one central air handler serving multiple units, which means a duct problem in one unit affects everyone.
Commercial jobs run on scope. A small professional office or duplex typically runs $500 to $1,200 depending on the number of units, register count, and duct accessibility. Larger apartment buildings require a site visit for an accurate quote. We give written pricing before work starts, we coordinate with tenants to minimize disruption, and we document everything with photos. Property managers get a digital invoice and a full report, not a handwritten receipt.
Video Inspection
Before we clean, we look. A small camera snake through the main trunk line shows us exactly what’s inside: crushed flex runs, rodent nests, disconnected joints, years of debris. We show you the footage. You decide what gets cleaned and what gets repaired. That’s the Relay Standard at work, no guesswork, no trust-me pricing.
Duct Sealing
Cleaning alone doesn’t fix a leaky system. In Lennox’s older homes, we routinely find supply registers that have pulled away from the duct boot, leaking conditioned air into the attic. After cleaning, we seal every register, reattach what has come loose, and check the static pressure. The result is a system that holds air and runs quieter than it has in years.
Trusted Brands We Service in Lennox
The equipment in Lennox homes runs the gamut: original Rheem and Carrier furnaces from the 1960s, newer Goodman and Lennox (no relation to your city, incidentally) systems, and everything in between. What matters to us is the ductwork, and we stock the parts Lennox jobs commonly need: galvanized connectors, flex duct in common local sizes, mastic sealant, and filter media from Honeywell, Aprilaire, and Guardsman. That means a reconnection or small repair doesn’t have to wait for a parts run across town. We arrive ready.
Common Air Duct Cleaning Problems We See in Lennox Homes
- Disconnected return ducts in crawlspaces. The most common failure in Lennox’s original 1940s – 1960s ductwork. When a return duct separates, it pulls in crawlspace air, insulation, and dust instead of household air, wrecking the blower motor and degrading indoor air quality. We find this on roughly a third of older Lennox homes we service.
- Rodent-chewed flex runs. Rats and mice live in Lennox crawlspaces, and they chew through flex duct like it’s cardboard. A single chewed run can dump half your conditioned air under the house while pulling debris into the system. We replace what’s beyond repair and seal what’s salvageable.
- Salt-air corrosion on metal ducts. Lennox sits close enough to the coast that marine layer humidity and salt air accelerate rust on galvanized ductwork. We see pinholes and flaking rust, especially in crawlspaces with poor ventilation. We clean what remains and recommend replacement or sealing where corrosion has gone too far.
- High-MERV filters choking older systems. Homeowners upgrade a cheap fiberglass filter to a high-MERV version, thinking it will improve air quality. On a 1960s furnace with original blower specs, it chokes airflow and can burn out the motor. We check filter compatibility on every job and tell you what your specific system can handle.

FAQs About Air Duct Cleaning in Lennox
Lennox’s housing stock is older and denser than what you’ll find in Hawthorne or Inglewood. Most single-family homes and duplexes were built between 1940 and 1965, with original galvanized ductwork in unconditioned attics and crawlspaces. Those systems have had sixty to eighty years to accumulate dust, soot, rodent debris, and blown-in insulation. Newer homes in nearby cities were built with tighter duct systems and modern sealing standards. Lennox simply has more accumulated history inside its ductwork. Call (424) 488-0361 for a free evaluation of your specific home.
The marine layer brings persistent humidity and salt air that accelerates corrosion on metal ductwork, especially in Lennox’s crawlspaces with limited ventilation. Galvanized ducts rust, pinholes form, and moisture promotes mold growth in poorly sealed systems. We check for corrosion on every job and recommend sealing or replacement where rust has compromised the duct. The coastal climate is a real factor here, one that generic duct cleaning companies rarely account for.
No. That smell is a telltale sign of decades of debris inside old ductwork. In Lennox’s many 1950s “Cinderella” homes, the distinctive mix of beach sand, eucalyptus debris, and decades of smog soot collects in ducts and produces a faint, acrid odor when the furnace kicks on. If you smell something burning or musty when the heat starts, your ducts likely need source removal cleaning, not just a filter change. We can identify exactly what’s inside with a video inspection and give you a written quote to remove it.
Yes. Sealing is standard on our full-system cleaning jobs, not an add-on. After we clean, we seal supply and return registers where they meet the duct boot, reattach any disconnected sections, and check static pressure. Older Lennox homes routinely have leaky or disconnected returns, so sealing is often the difference between a system that works and one that wastes conditioned air into an attic or crawlspace. The sealing is included in the written quote, never a surprise line item.
Yes. We coordinate directly with property managers and tenants to schedule a time that minimizes disruption. For duplexes and small apartment buildings, we typically clean one unit at a time, use containment around the work area, and keep noise and dust controlled. The process takes four to six hours per unit, and we document everything with photos so you can see exactly what was done. If you’re a Lennox landlord or property manager, call (424) 488-0361 for a written quote on your specific building.
