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.

AfterLennox Air Duct Cleaning in Long Beach, CA | Hollis Air Duct Cleaning
We provide independent Lennox air duct cleaning service across our Long Beach service area, and the thing that sets our work apart here is simple: we clean Lennox ductwork based on the specific air this city moves. Salt-laden marine air, port-zone diesel particulates, and persistent coastal humidity interact with Lennox equipment in ways a generic duct cleaning crew misses. Roy Castellanos and our team have spent years watching how Lennox coils, blowers, and flex runs behave within a mile of the shoreline versus up near Lakewood-adjacent tracts. Call (361) 326-5060 for a free estimate, and you’ll get a written price before any work begins.
Why Long Beach Residents Choose Us for Lennox Service
Roy Castellanos grew up in Boyle Heights and learned the mechanical trades through the sheet metal and air conditioning program at Los Angeles Trade-Technical College before spending years doing hands-on duct work across Los Angeles County. That background means he approaches Lennox systems the way a mechanic approaches an engine: watch how it actually runs, then diagnose from observed airflow rather than a sales script. We’re an independent Lennox service provider, not a factory-authorized shop, and we’re direct about what that means. No one pays us to push parts. We stock what’s needed for fast Long Beach turnarounds, and we tell you plainly whether OEM or aftermarket makes sense for the job.
Homeowners between 35 and 65 have usually been through the wringer with duct cleaning outfits that quote one number on the phone and present another at the door. We operate under The Garrison Standard: arrive inside the quoted window, put the price in writing before work starts, complete the job by the book, and leave the site clean. Our technicians are background-checked and uniformed. The 365-Day Done Right Promise covers every Lennox job in writing for a full year. If something fails, we come back at no charge. That’s the discipline, not a marketing line.

Common Lennox Air Duct Cleaning Problems We Solve in Long Beach
- Salt-and-diesel film on all-aluminum evaporator coils. Lennox cased upflow and downflow air handlers near the Port of Long Beach collect a sticky dark residue from marine salt and diesel particulate. It cuts heat transfer, strains the blower, and can overflow the condensate pan. We clean coils with professional agitation and HEPA vacuuming rather than just wiping the face.
- Musty odors from high-efficiency condensing furnaces. The Lennox SLP98 and EL296 pull humid marine-layer air into the cabinet and duct transitions. Secondary heat exchangers hold moisture longer than single-stage units, and that dampness travels into supply runs. We address the duct-side mold-like growth and explain when the coil or cabinet also needs attention.
- Crushed or detached flex duct liners in older attics. 1920s bungalows east of downtown and post-war tract homes near Lakewood often have original or poorly sealed flexible duct runs. When inner liners detach, fiberglass insulation and grit enter the airstream. We inspect with video, repair or advise replacement, and seal takeoffs with mastic.
- High static pressure faults on variable-speed blowers. Lennox constant-torque and constant-CFM ECM blowers in beach-adjacent condos struggle when return ducts are undersized and fouled. A dirty coil plus a restricted return triggers faults and shortens blower life. Cleaning the full duct path often resolves the code without replacing the motor.
- Shared-chase contamination in downtown conversions. High-rise condos and converted lofts often tie multiple Lennox air handlers into common vertical shafts. One unit’s dust and mildew spreads to neighboring floors. We use negative-air containment and video inspection on these stacked systems to prevent cross-contamination.
Lennox Service in Long Beach: What Local Conditions Mean for Your Equipment
Long Beach’s marine layer and salt-laden onshore breeze create a year-round moisture and chloride problem inside ductwork, especially in homes within a mile of the port or shoreline. Ducts collect a sticky film of salt and pollutants that causes musty odors and accelerates corrosion. No neighboring city west of the Palos Verdes Peninsula or south of the 405 has this combination of port emissions and persistent coastal humidity. For Lennox owners, that means evaporator coils and duct transitions hold a chloride-heavy film that inland homes simply don’t accumulate. It also means Santa Ana winds, when they arrive, dump fine grit into fresh-air intakes and dryer vents after weeks of damp air has already softened the grime. A standard dust-only cleaning won’t touch that layered buildup. You need agitation, HEPA vacuuming, and a crew that knows what Long Beach air actually deposits inside a Lennox system.
Lennox Models & Products We Service in Long Beach
We service the Lennox Dave Lennox Signature Collection including the SL280 and SLP98 high-efficiency furnaces and air handlers, the Merit Series including the ML180, ML195, and ML14XC1, and the Elite Series including the EL180, EL296, and EL16XC1. We also clean and inspect Lennox PureAir and Healthy Climate ducted indoor air quality accessories. For parts, we use genuine Lennox OEM components when they’re available and form-fit-function correct. For items like flex duct, mastic, and vent caps, high-quality aftermarket equivalents often make better sense on coastal homes where corrosion eats everything anyway. We’ll tell you which path we recommend and why, before we order anything.
Lennox Service Pricing in Long Beach
Lennox air duct cleaning in Long Beach typically runs $400 to $800 for a full system, depending on home size, number of returns, and how much port-zone residue has built up.

FAQs – Lennox Air Duct Cleaning in Long Beach
Yes. Port-zone air carries diesel particulate and marine salt that form a dark, sticky film on Lennox coils and duct interiors. Standard dust removal doesn’t break that film loose. It requires mechanical agitation and HEPA vacuuming to remove, and it returns faster than household dust alone. If you live within a mile of the port, budget for more frequent coil cleanings. Call (361) 326-5060 for a quote based on your exact location.
The odor is likely coming from mold-like growth inside the shared duct chase or on the coil, not the filter. Downtown high-rise condos and converted lofts often tie multiple Lennox air handlers into common vertical shafts, so one unit’s moisture problem spreads through the entire chase. We also service Lennox in Manhattan buildings with similar configurations. We use video inspection and negative-air containment to identify the source and clean your unit without pushing debris into a neighbor’s. Call (361) 326-5060 for a free assessment.
Often yes. Lennox constant-torque and constant-CFM ECM blowers are sensitive to restricted airflow, and a fouled coil combined with dirty or collapsed return ducts raises static pressure enough to trigger fault codes. Cleaning the full duct path and restoring return airflow frequently clears the fault without replacing the blower. If the blower is already damaged, we’ll do an honest post-clean assessment. Call (361) 326-5060 to schedule an inspection.
The marine layer keeps humidity high but rarely brings enough heat to dry out ductwork. That persistent dampness encourages mold and mildew growth inside ducts, so Lennox coils and duct interiors in Long Beach typically need cleaning every two to three years instead of the four to five years common inland. Homes within a mile of the port may need annual coil attention. Call (361) 326-5060 and we’ll give you a realistic schedule for your neighborhood, not a generic timeline.
We use genuine Lennox OEM parts when they’re available and the right fit. For non-critical items like flex duct, mastic, and vent caps, we often recommend high-quality aftermarket equivalents because coastal corrosion makes OEM cost hard to justify and the aftermarket product performs as well or better. We explain the difference before ordering anything. Call (361) 326-5060 if you want to walk through options for your specific Lennox system.
