Air duct cleaning in San Pedro typically costs between $350 and $650 for a full single-system home, with most jobs completed in four to six hours.

We know San Pedro’s streets from Western Avenue up into the hills above Gaffey, and we know how this port town treats a house. The salt air off the breakwater doesn’t just rust your car. It gets into your ductwork, and it does not leave on its own.
Why Hollis Air Duct Long Beach Is San Pedro’s Preferred Air Duct Cleaning Company
The crews we send into San Pedro work under The Garrison Standard, which is our written code for how a job goes: arrive inside the quoted window, put the price in writing before touching the system, complete the work by the book, and leave the site clean. No exceptions, no “the foreman has to approve a change order.” The price quoted is the price you pay.
We have been doing this since 2004, and we have cleaned ducts in just about every corner of San Pedro: flat-roofed 1950s tract homes in Vista del Oro, craftsman bungalows near Point Fermin, and the newer hillside builds that catch every onshore breeze. Our technicians are background-checked and uniformed, so you know who is walking through your front door before they arrive. When you call, a live person answers, 24/7. Not a voicemail loop. Not a call center that promises a callback next week.

Air Duct Cleaning Services in San Pedro
Air Duct Cleaning Services in San Pedro are something we approach differently than inland companies do, because the failure mode here is different. A full system clean in San Pedro runs $350 to $650 for a typical single-system home. That includes the supply and return sides, registers, the plenum, and the blower compartment. We use negative-air machines from Nikro with HEPA filtration to keep the extracted dust from re-entering your living space, and rotary brush systems to scrub what the airflow alone cannot lift.
Full System Cleaning
We run a HEPA-filtered negative-air machine at the furnace and work every supply and return register with agitation tools until the dust, salt, and rust scale are out of the system. In San Pedro homes, this matters more than inland because the salt-laden buildup clings to galvanized duct surfaces and needs mechanical agitation to break it free.
Supply and Return Duct Cleaning
Supply ducts push conditioned air out; return ducts pull room air back to the furnace. Both get dirty, but we find the return side in older San Pedro homes is often worse because unsealed joints pull marine-layer moisture and crawlspace dust into the system. We clean both sides completely, then check for leaks that let coastal air back in.

HVAC Duct Cleaning in San Pedro
HVAC Duct Cleaning in San Pedro means cleaning the entire air pathway, not just the visible registers. The price for a full HVAC duct cleaning here runs $350 to $650 depending on home size and the number of systems. We do not price per vent, and we do not advertise a low teaser price that balloons once the technician is standing in your hallway. The written estimate covers the whole system.
Video Inspection
Before we start, we run a camera through the main trunk lines to see what is actually inside. In San Pedro, that usually means rust-tinted dust, salt crystals, and sometimes visible mold at the register boots. We show you the footage. You decide what gets cleaned. No pressure, no mystery.
Return Duct Deep Cleaning
Return ducts in hillside San Pedro homes often sit in crawlspaces and pull damp, salty air through unsealed joints. We clean the entire return side, then seal accessible joints with mastic so the system stops pulling harbor air into your house. That sealing step is the difference between a clean system that stays clean and one that is dirty again in nine months.
Trusted Brands We Service in San Pedro
The systems we clean in San Pedro run everything from 1970s gravity furnaces to modern heat pumps, and the work we do works on all of them. We use professional-grade equipment from Nikro for negative-air extraction and we recommend filtration upgrades from Honeywell and Aprilaire when a system needs better protection against San Pedro’s fine salt particulates. Our equipment is the same gear commercial crews use on hospital and school jobs, not hardware-store specials. That matters in a coastal environment, because consumer-grade vacuums simply do not have the suction or filtration to remove rust scale and salt-laden dust from duct interiors.
Common Air Duct Cleaning Problems We See in San Pedro Homes
- Rust-tinted dust that smells like the harbor. In homes near the port and along the coastal bluffs, we regularly find a fine rust-colored powder coating the inside of ducts. It is a mix of salt, rust, and marine-layer dust that has been drawn in through leaky registers and is recirculating through the house.
- Mold at the register boots in bungalows and bluff homes. The humid, salt-laden air that seeps through unsealed ductwork creates condensation at the registers. In older homes near Point Fermin and Vista del Oro, this frequently leads to mildew growth that gets pushed into living spaces every time the furnace runs.
- Corroded galvanized duct interiors in pre-1970s construction. San Pedro has thousands of mid-century homes with original unlined galvanized ductwork. The salt air corrodes the metal from the inside, and the rust scale holds moisture, which holds mold. A generic cleaning that just vacuums the register openings never addresses this.
- Marine-layer-laden dryer vent lint. Dryer vents in San Pedro homes, especially runs through hillside crawlspaces or garages, trap humidity-streaked lint that clumps and sticks to the vent walls. This is a fire risk that inland homes simply do not face to the same degree.

AfterPricing for Air Duct Cleaning in San Pedro, CA
You should also know what is not worth paying extra for. Many companies in the LA area sell a “fogging sanitizer” upsell for $200 to $400, implying it kills the mold. Fogging does not remove mold colonies or salt buildup or rust scale. It is a temporary chemical smell that masks the underlying problem. A real clean removes the material. We will tell you if fogging is a waste of your money, and in most San Pedro systems, it is.

FAQs About Air Duct Cleaning in San Pedro
San Pedro homes near the port and the bluffs get mold in ductwork faster because salt-laden marine air enters through unsealed registers and joints, then condenses on the cooler metal surfaces inside the ducts. The resulting moisture plus the organic dust that blows in from the harbor creates a breeding ground for mold and mildew, especially in older galvanized systems where rust scale holds water. Inland homes in the same county do not have salt spray or the same humidity loading, so their ducts stay dry and the same mold problem simply never starts.
Yes, a complete air duct cleaning removes the salt smell from a San Pedro HVAC system because the odor comes from physical material inside the ducts, not from the air itself. That material is salt-laden dust, rust scale, and sometimes mold or mildew. When the buildup is agitated and extracted with HEPA-filtered negative-air equipment, the smell goes with it. A fogging treatment alone will not accomplish this because it does not remove the source. Call (562) 548-7365 for an assessment and written estimate.
In a coastal San Pedro house, air ducts should be cleaned every two to three years, more often than the five to seven year interval typical for inland homes. The salt air and marine-layer moisture accelerate buildup and microbial growth faster than dry inland dust does. If you live within a mile of the water or near the port, or if your system predates 1980, plan on the shorter end of that range.
No, fogging sanitizers do not replace a real duct cleaning in San Pedro’s salt air. Fogging deposits a chemical mist that may temporarily mask the smell, but it does not remove the salt, rust scale, or mold colonies adhered to the duct walls. In San Pedro’s humid coastal environment, the remaining material continues to hold moisture and regrow. Only mechanical agitation with HEPA-filtered extraction removes the buildup and eliminates the source. We will show you the camera footage before and after so you can see the difference.
Air duct cleaning addresses the HVAC system that heats and cools your home; dryer vent cleaning addresses the dedicated duct that exhausts your dryer to the outside. They are separate systems with separate problems. In San Pedro, dryer vents are particularly prone to clumping from the humid air, which makes them a fire hazard faster than dryer vents inland. Most homes need both services, and the combined cost typically falls between $500 and $800 when done together.
Key Takeaways
- San Pedro’s salt air is the root cause of most duct problems here: rust scale, salt-laden dust, and mold growth driven by marine-layer moisture.
- Real cleaning costs $350 to $650 for a typical single-system home in San Pedro, with larger two-system homes running up to $950.
- The price is written before we start, and it does not move. No per-vent pricing, no door-step upcharges, no fogging upsell unless it actually makes sense.
- The 365-Day Done Right Promise covers every job in writing. If the work fails within a year, we return and fix it at no charge, including a free second visit.
- You get camera footage of the inside of your ducts before and after the clean. You see exactly what was removed.
