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 Lomita
Air duct cleaning in Lomita typically runs $350 – $650 for a full residential system and is scheduled by appointment, with most jobs completed in three to five hours. Our crews dispatch from the Los Angeles office and serve Lomita directly, carrying the same Rotobrush and Nikro equipment we use on commercial sites throughout the South Bay.
We’re familiar with the tight postwar tracts off Lomita Boulevard, the bungalow courts near Narbonne Avenue, and the low-clearance crawlspaces that run under the 1940s – 1960s stock that dominates this city. That local knowledge matters because Lomita ducts fail in specific ways, shaped by the marine layer that sits idle for months and the piston-engine traffic overhead from Torrance Municipal Airport. If you’re seeing black dust at your return grilles, smelling mildew when the system kicks on, or you’ve never had the ducts opened since you bought the place, call us at (361) 326-5060. We’ll give you a written price before any work starts, and every job carries our 365-Day Done Right Promise.
Why Hollis Air Duct Cleaning Is Lomita’s Preferred Air Duct Cleaning Company
We’ve been in business since 2004 as part of the Garrison Partners family, and our Air Duct Cleaning team has built a reputation in Lomita by showing up inside the quoted window, pricing in writing, and leaving the site clean. That’s The Garrison Standard, and it applies to every job we run in the South Bay.
Our technicians are background-checked and uniformed, you’ll know who’s arriving before they knock, and our phones are answered by a live person 24 hours a day, seven days a week. No voicemail loops. No callback queues. When you schedule in Lomita, you’re dealing with an independently owned and operated location that answers to its customers, not a distant call center.
The 365-Day Done Right Promise covers every repair and cleaning we perform. If the work fails within a year, we return and make it right at no charge, including a free second visit. We put that in writing on every job, because a verbal “satisfaction guarantee” isn’t worth the paper it isn’t printed on.
Air Duct Cleaning Services in Lomita
Air Duct Cleaning Services in Lomita cover the complete removal of dust, debris, microbial growth, and carbon-fouled particulate from your supply and return ductwork using source-removal methods, not chemical masking. A typical residential full-system clean in Lomita runs $350 – $650 depending on the number of vents, the accessibility of the crawlspace or attic runs, and whether we find disconnected joints or pinched flex that needs reconnection. Most Lomita homes built between 1940 and 1975 have rectangular galvanized steel trunk lines with shallow crawlspace access, which takes longer to navigate properly but must be done right to avoid disturbing old asbestos-wrapped boots.
Residential Duct Cleaning
We clean the full supply and return network in single-family homes, townhouses, and duplexes throughout Lomita’s postwar neighborhoods. Our process starts with a video inspection so you see what we see, followed by negative-air HEPA extraction and rotary brush agitation through each run. We finish with a second camera pass to confirm the trunk lines are clear and the joints are sealed.
Commercial Duct Cleaning
Small commercial buildings along Pacific Coast Highway and the mixed-use corridors near Lomita Boulevard get the same equipment roster, scaled to the larger square footage and extended duct networks. We schedule around your business hours to avoid disrupting operations, and we provide written documentation of the cleaning scope for property managers and landlords.

HVAC Duct Cleaning in Lomita
HVAC Duct Cleaning in Lomita addresses the entire forced-air system, including the furnace cabinet, blower assembly, evaporator coil housing, and the duct runs that distribute conditioned air through your home. Because Lomita’s mild coastal climate means HVAC systems often sit idle for months at a time, dust, mold spores from ocean moisture, and rodent debris accumulate without the constant airflow that would otherwise keep passages cleaner. A full HVAC duct cleaning in Lomita typically runs $400 – $750 when the furnace cabinet and coil housing are included, with older systems at the higher end due to the careful handling required around original components.
Supply Duct Cleaning
Supply ducts push conditioned air into your living spaces. In Lomita’s 1950s and 1960s tracts, these are often rectangular galvanized runs with rigid transitions to floor or wall registers. We use rotary brush systems with controlled torque to dislodge buildup without damaging the original metal, then extract under negative pressure so debris doesn’t migrate into your rooms.
Return Duct Cleaning
Return ducts pull air back to the furnace for reconditioning. In Lomita, these are where we most often find the black, carbon-fouled residue from Zamperini Field piston-engine traffic, combined with damp marine-layer dust that compacts into a film ordinary vacuums won’t touch. Our Nikro negative-air machines with HEPA filtration are specifically designed to extract this type of heavy, oily particulate without redistributing it through your home.
Trusted Brands We Service in Lomita
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines for controlled extraction, and filtration products from Honeywell, Aprilaire, and Guardsman for homeowners who want to upgrade their system after cleaning. We stock common filtration sizes and mounting hardware for Lomita’s typical residential furnaces, so if your old 1-inch fiberglass filter has been sagging into the return boot since 2018, we can replace it with a properly fitted pleated media on the same visit. For homes with Aprilaire or Honeywell whole-house air cleaners already installed, we carry the replacement media locally and can service the cabinet during the duct cleaning appointment rather than making you schedule a second trip.
Common Air Duct Cleaning Problems We See in Lomita Homes
- Black return-grille residue from Zamperini Field traffic. The piston-engine leaded-avgas exhaust settles as a distinctive carbon-fouled dust in return ducts under the flight path, especially in homes north and east of the airport. Generic inland crews often misread this as ordinary household dirt and skip the aggressive source-removal pass it actually requires.
- Disconnected joints in low-clearance crawlspaces. Lomita’s 1940s – 1960s tract homes on pier-and-beam or shallow slab foundations have short duct runs with minimal access height. Decades of settling pop joints loose, pulling unconditioned, damp marine-layer air into the system and creating the mildew smell homeowners mistake for dirty ducts.
- Pinched flex duct under settled foundations. The 1970s-era homes near the Lomita Boulevard/Pacific Coast Highway corridor often have flex duct compressed under low pier-and-beam framing by decades of soil movement. This restricts airflow, strains the blower motor, and creates dead zones where moisture collects.
- Asbestos-wrapped boots disturbed by uninformed cleaning. Pre-1975 builds in Lomita may have original galvanized trunk lines with asbestos-containing insulation at the register boots. Crews who skip the camera inspection and run aggressive brushes blindly can friable this material, violating NADCA standards and creating a hazardous condition.
Pricing for Air Duct Cleaning in Lomita, CA
A typical full-system residential air duct cleaning in Lomita runs $350 – $650. HVAC duct cleaning that includes the furnace cabinet and evaporator coil housing runs $400 – $750. Dryer vent cleaning, which we often pair with duct cleaning in Lomita’s older homes with long vent runs through crawlspaces, adds $120 – $180. Video inspection is included at no charge when you proceed with the cleaning.
What moves you within those ranges: the number of supply and return vents, whether we need to navigate a shallow crawlspace or attic, the condition of the ductwork (disconnected joints or pinched flex take time to repair properly), and whether we find material that requires special handling. We do not quote per-vent teaser prices that balloon once the technician is inside. We give one flat price per system, agreed in writing before any work starts. Estimates are free. Call (361) 326-5060 to schedule.

FAQs About Air Duct Cleaning in Lomita
That black residue is carbon-fouled particulate from piston-engine leaded-avgas exhaust under the Torrance Municipal Airport flight path, not ordinary household dirt. It requires source-removal agitation with rotary brushes and negative-air HEPA extraction, not a standard vacuum pass. Call (361) 326-5060 for a video inspection and written estimate.
Yes. The damp marine layer that sits over Lomita for weeks each spring and early summer keeps HVAC systems idle, letting moisture accumulate in low-clearance crawlspace runs where airflow would otherwise keep things dry. The actual fix is finding and sealing the disconnected joint or leak that’s pulling that damp air in, not fogging a chemical mist that does nothing for a mechanical failure. We camera-inspect first, then repair, then clean.
It is safe when done with a camera inspection first and controlled-agitation tools matched to the material. The risk comes from crews who skip the inspection and run aggressive brushes blindly past asbestos-wrapped boots or corroded seams. Our process starts with a video scope so we know what we’re working with before any tool enters the duct. If we find material that requires abatement referral, we tell you before we proceed.
No. Fogging mist does not fix a disconnected joint or pinched flex duct that’s pulling damp marine-layer air into your crawlspace runs. It masks odor temporarily while the underlying moisture problem continues. We don’t sell fogging upsells because they’re the wrong solution for Lomita’s actual failure modes. We repair the mechanical problems, remove the source contamination with physical agitation and extraction, and guarantee the work for 365 days.
Every three to five years for most Lomita homes, or sooner if you see black residue at returns, smell mildew when the system starts, or have never had the ducts opened since purchase. Homes with original galvanized steel and no prior cleaning may need an initial deep clean followed by a shorter interval to establish baseline condition. Call (361) 326-5060 and we’ll camera-inspect to give you a specific recommendation based on what we find.
