Fast, Reliable Air Duct Cleaning Across San Pedro
Air duct cleaning in San Pedro usually runs $450 – $900 for a full system on a typical 2,000-square-foot home, and most jobs are finished in four to six hours. That price reflects what we actually find here: salt-laden dust, diesel soot from the Port of LA, and corroded galvanized joints inside ducts that haven’t been opened in decades. If you’re noticing musty air, weak airflow from certain registers, or dust settling back on furniture within days of wiping it down, your ductwork is part of the picture. Call (833) 593-4030 for a free estimate. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.

Why San Pedro Homeowners Call Fortress Air Duct Cleaning for Air Duct Cleaning
Most of the homes we work on in San Pedro are older. 1920s bungalows off Gaffey, 1940s and 50s stucco houses near Leland Street, and 1960s tract homes up in 90732. These systems weren’t designed for the marine layer we live with every year. Homeowners here call us because they can see rust-colored dust around their registers or smell something stale each time the furnace kicks on, and they want a crew that knows what that means in a port town.
Our teams have cleaned ducts from Point Fermin to the Harbor Highlands, and the pattern holds: homes closer to the water and the port show heavier salt crusting and soot buildup than houses farther up the hill. That’s local knowledge that shapes how we approach every job. We’re not running a generic checklist. We’re looking for the specific corrosion and disconnected-run problems that San Pedro’s coastal air creates. Lloyd Farrell founded Fortress Air Duct Cleaning in 2017 with that very focus: professional-grade tools, honest findings, and repair capability on the same visit.

Ductwork Cleaning in San Pedro
Ductwork cleaning here means source removal, not just brushing what you can reach. In San Pedro, the biggest issue inside ductwork is a salt-crusted interior. Marine air carries salt aerosol inland, and the Port of LA adds diesel particulate on top of it. Together they form a sticky, slightly corrosive film on duct walls, blower motors, and coils.
We clean this with Rotobrush and Nikro equipment under negative pressure, so debris is pulled out of the system rather than pushed around the house. The agitation loosens salt deposits and soot from galvanized interiors, while the vacuum captures everything at the source. A standard full-system cleaning in San Pedro runs $450 – $900. Older homes near the harbor with heavy buildup can run higher, and we’ll show you exactly why before any work begins.
Supply and Return Runs
Supply ducts carry conditioned air into your rooms. Return ducts pull air back to the air handler. Both get coated in San Pedro’s marine soot, but returns often collect more because they handle unfiltered air from the house. We clean both as part of a full system, and we check for disconnected runs at the same time.
Camera Inspection Add-On
We run a video inspection camera through the ducts before and after cleaning. In San Pedro homes, this catches issues that a visual check alone misses: collapsed flex sections, separated joints, and corrosion that has eaten through thin galvanized metal. The inspection runs $150 – $250 and is worth it in any home built before 1980.
Air Duct Inspection in San Pedro
An air duct inspection in San Pedro is a camera walkthrough of your duct system, and its main value here is finding failures before they cost you more in heat, cooling, and air quality.
We use a small, high-resolution camera pushed through each run. It shows us the inside of ducts that haven’t been opened since they were installed. In San Pedro’s older homes, this regularly reveals galvanized joints that have corroded from the inside, disconnected runs, and crushed flex duct behind air handlers. An inspection alone costs $150 – $250. If you combine it with cleaning, we often discount the inspection, and we review the footage with you before recommending any repair.
What We Document
Every inspection includes before-and-after stills of the duct interior. You’ll see the salt deposits, soot, and any corrosion the camera finds. This documentation matters in San Pedro, because corrosion near the harbor progresses faster than most homeowners expect.

Post-Cleaning Verification
After cleaning, we inspect again to confirm the interior is clean and sealed. If we find tears, collapsed sections, or failed joints, we can repair them the same day. That’s the difference between a cleaning company and a duct specialist who can also do Air Duct Cleaning repairs on the spot.
Trusted Brands We Service in San Pedro
We work on systems connected to Honeywell and Aprilaire filtration setups, and we use Abatement Technologies and Guardsman products when a job calls for surface sealing or protective treatment. Our Rotobrush and Nikro equipment is the same contractor-grade gear used in commercial and remediation work, not a truck-mounted vacuum you’d find at a budget operation. For San Pedro customers, that means we can handle the heavy salt and soot loading your ducts carry, and we can talk intelligently about your filtration system instead of treating it as an afterthought.

AfterCommon Air Duct Cleaning Problems We See in San Pedro Homes
- Salt-crusted galvanized joints. Marine air corrodes galvanized duct seams from the inside, and after decades, the joints leak. We find this in homes near Western Avenue and along the coastal bluffs more than anywhere else in the South Bay.
- Collapsed or torn flex duct. 1960s and 70s tract homes in 90732 often have original flex duct that has become brittle. At bends, it tears or collapses, sending air into wall cavities instead of your rooms.
- Disconnected runs. A separated duct joint is invisible from outside and quietly wastes a third of your airflow. Camera inspection is the only way to confirm it, and we find disconnected runs in older San Pedro homes more often than not.
- Sticky soot on blowers and coils. Diesel particulate from the Port of LA mixes with marine humidity and coats blower motors and evaporator coils. This reduces airflow and can shorten equipment life if left untouched.

FAQs About Air Duct Cleaning in San Pedro
Marine air carries salt aerosol, which settles inside ducts and corrodes galvanized metal from the inside out. Add diesel soot from the Port of LA, and you get a sticky, corrosive residue that inland LA homes simply don’t experience. Your ducts may need sealing and repair in addition to cleaning. Call (833) 593-4030 for an inspection.
We usually find some combination of salt crusting on duct interiors, corroded seams, disconnected runs, and collapsed flex sections near the air handler. Homes built in the 1920s through 1970s often have original duct materials that have never been opened.
Source removal means extracting the soot, salt, and debris from the duct interior rather than brushing it loose. In San Pedro, diesel soot binds with marine humidity into a film that a simple vacuum won’t lift. We use Rotobrush and Nikro equipment under negative pressure to remove the source material itself.
Yes. We clean ducts in condos and townhomes throughout 90732, including buildings with tight mechanical closets and rooftop air handlers. The equipment adjusts to the access available, and the process typically takes three to four hours for a two- or three-room unit. Call (833) 593-4030 for a free estimate.
If our camera inspection shows corroded joints, disconnected runs, or torn flex duct, sealing is necessary. Cleaning removes buildup but can’t fix structural leaks. We review the footage with you and provide a repair quote before any sealing work begins.
