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.

Why Kestrel Air Duct Cleaning Is Hermosa Beach’s Preferred Air Duct Cleaning Company
We’ve been working under the Kingswell Guarantee since 2004, and that same written standard travels with our Air Duct Cleaning team into every Hermosa Beach home. The Kingswell Way means we say the price, show up in the window we gave, leave the place cleaner, and put our guarantee in writing. If the work falls short within a year, we come back and make it right at no charge. That’s not a promotional offer. It’s how every single visit operates.
Our technicians are background-checked, uniformed, and trained on Rotobrush rotary brush systems, Nikro negative-pressure units, and Abatement Technologies HEPA filtration. Real equipment, not box-store shop vacs. Calls are answered by a live person, 24/7, not a voicemail queue.
Hermosa Beach homeowners know the difference because they’ve dealt with the alternative: a low quote that doubles once the truck is in the driveway, or a technician who disappears after the invoice is paid. We don’t do that. The written price is in your hands before a single vent is touched. No door-step revisions.
Air Duct Repair in Hermosa Beach
Air Duct Repair in Hermosa Beach usually starts with a camera inspection that reveals what the salt air and marine layer have done to ductwork hidden in attic spaces or behind walls. We find separated flex duct connections, corroded collars at the plenum, and crushed runs where retrofitted systems were forced through crawl spaces never designed for HVAC. A typical repair runs $280 to $580 for re-sealing and patching; replacing corroded flex sections or rebuilding plenum connections can reach $720 to $1,100 in homes where salt-air oxidation has advanced.
Corroded Collars and Joint Separation
The chloride-rich marine air in Hermosa Beach attacks metal duct collars and flex connections years before identical materials fail inland. Our techs regularly find joints that have worked loose or corroded through entirely, especially on west-facing beach-side blocks where onshore flow is constant. We cut out the damaged section, install a fresh connection under negative-air extraction, and test the seal before we leave.
Crushed or Disconnected Runs in Retrofitted Systems
Beach bungalows built in the 1940s and 1950s weren’t designed for central air. Flex duct routed through cramped attics gets kinked, stepped on during roofing work, or pulled loose by thermal expansion. We map the full system with video inspection, identify every compromised run, and give you a written repair scope before touching tools.
Ductwork Cleaning in Hermosa Beach
Ductwork Cleaning in Hermosa Beach removes decades of accumulated debris from systems that have been pulling salt-laden coastal air through original or retrofitted ductwork since the day they were installed. A full system cleaning for a typical Hermosa Beach home runs $380 to $720, with larger three-story townhomes or commercial spaces ranging $620 to $1,100 depending on access and system complexity. We clean supply ducts, return ducts, and the main trunk lines with Rotobrush agitation tools that physically dislodge debris from duct walls, paired with Nikro negative-pressure extraction that pulls contaminants out of your home entirely.
Negative-Air Extraction with HEPA Containment
Our Abatement Technologies HEPA filtration keeps loosened particles out of your living space during cleaning. The system creates a vacuum seal at the duct opening so nothing escapes into the rooms where your family breathes. We show you the before-and-after with our camera so you see what came out.
Supply and Return Duct Specifics
Supply ducts push conditioned air to your rooms; return ducts pull air back to the handler. In Hermosa Beach, return ducts often show the heaviest salt and mold loading because they’re drawing air from inside the home where marine-layer humidity has been circulating for months. We clean both sides of the system, not just the vents you can see.
Trusted Brands We Service in Hermosa Beach
We clean ductwork connected to every major HVAC brand, and we stock Aprilaire and Guardsman filtration products for Hermosa Beach homeowners who want to maintain cleaner air between service visits. The salt-rich coastal environment here destroys standard filters faster than inland climates, so we often recommend upgrading to a MERV rating that actually captures chloride-rich particulates. If your system needs a filtration upgrade after cleaning, we carry the hardware and install it same visit. No waiting on parts, no return trip.
Common Air Duct Cleaning Problems We See in Hermosa Beach Homes
- Salt-air corrosion in retrofitted flex duct. The beach bungalows near The Strand and Pier Avenue were built decades before central AC existed. Flex duct added later corrodes at joints and collars years before the same materials fail in Torrance or Gardena. We find separated connections on camera and re-seal under negative pressure.
- Mold and mildew from persistent marine-layer moisture. The June Gloom layer traps humidity inside ductwork for months, especially in homes without adequate attic ventilation. What starts as a routine cleaning often reveals mold colonies that need remediation before the system is safe to run.
- Poorly sealed original duct runs letting coastal particulates bypass filtration. Cramped attic spaces in 1940s-1960s cottages make proper sealing nearly impossible. Unfiltered salt air loads the blower motor and air handler with debris no inland system collects at the same rate.
- Crushed or kinked flex in three-story townhomes. The newer dense housing along Hermosa Avenue and Pacific Coast Highway packs ductwork into tight chases where it gets damaged during construction or maintenance. Video inspection finds what visual checks miss.

FAQs About Air Duct Cleaning in Hermosa Beach
Yes. Hermosa Beach’s direct Pacific exposure means salt-laden marine air circulates through your duct system constantly, even when sealed, accelerating corrosion and depositing chloride-rich particulates that inland homes five miles east simply don’t face. The May-through-September marine layer adds persistent moisture that creates mold conditions rare in drier inland climates. Call (469) 972-3151 for an inspection if you smell mustiness when the AC runs.
Expect retrofitted flex duct routed through cramped attic spaces with joints and collars that may have corroded or separated from salt-air oxidation. We start with video inspection to map every run, identify compromised connections, and show you what we’re dealing with before quoting repair work. The cleaning itself uses Rotobrush agitation and negative-air extraction to remove decades of accumulated salt and debris. Call (469) 972-3151 to schedule.
Every three to five years for most homes, but every two to three years if you’re within a few blocks of the beach where salt and moisture loading is heaviest. Homes with visible mold, musty odors, or recent construction should be inspected immediately regardless of schedule. Call (469) 972-3151 and we’ll tell you whether you’re due.
We handle both. When our camera inspection finds mold colonies inside ductwork, we apply antimicrobial treatment as part of the cleaning scope, quoted upfront before work begins. Severe contamination may require additional remediation steps; we’ll show you the extent on camera and give you a written price for the full solution. Call (469) 972-3151 for an assessment.
It’s usually a duct problem, specifically moisture accumulation and mold growth inside the system. In Hermosa Beach, the marine layer keeps duct interiors damp for months, creating ideal conditions for mildew. Our techs drop a camera inspection into the first accessible run to confirm the source before we quote any work. Call (469) 972-3151 - we’ll pinpoint it and give you the fix in writing.
