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 San Pedro
Air duct cleaning in San Pedro typically runs $425-$780 for a full single-system home, and the job usually takes 4 to 6 hours with a two-person crew. That price includes every supply and return run, the plenum, the blower compartment, and a camera record of the before and after. If you live near the port in Barton Hill, downtown San Pedro, or the hills above the harbor, your ducts are collecting something most of greater Los Angeles never sees: a heavy black-gray diesel soot that settles into every register and coats the inside of the ductwork. We know this because we photograph it on every job. Call (806) 606-6902 and we’ll put a written price in front of you before a single panel comes off.
Why CleanRun Air Duct Cleaning Is San Pedro’s Preferred Air Duct Cleaning Company
We work in San Pedro every week, and our technicians know the difference between the gravity-era duct systems in a 1920s California Foursquare off Pacific Avenue and the post-war tract homes north of Gaffey. That matters when the question is not just “how much dust” but “where is the air actually leaking, bypassing, or re-entering.” San Pedro customers typically book with us after a neighbor shows them the photo record from a finished job. Our crews arrive in uniforms, background-checked, and identified by name before they step out of the truck, per Haven Standard Clause 3.
Every job ends with a Documented Photo Record of every duct run, delivered to your phone and your inbox. That practice has been standard for us since our first job in 2013, not a recent add-on. We also carry a 365-Day Done Right Promise in writing on every invoice. If a run was missed or a disconnect was not sealed, we return and make it right. No manager approval needed, no fine print. Tomas Reyes, our owner, checks the photo logs personally.
We serve all of San Pedro, including Barton Hill, the downtown blocks near the harbor, Vista del Oro, and the hillside streets above Western Avenue. Scheduling is coordinated through our Los Angeles office, but the crews you see in San Pedro work here regularly and know these houses.
Our Air Duct Cleaning Services in San Pedro
Residential Duct Cleaning
A full residential clean in San Pedro covers every supply and return run, the supply plenum, the return plenum, and the blower compartment. In older homes near the port, we typically find a 1/4-inch to 1/2-inch layer of gray-black particulate adhered to the duct walls. We remove it with negative-pressure extraction, not a shop vac. That distinction matters in San Pedro more than almost anywhere else in Los Angeles County, because agitation without containment pushes port soot through the register and into the living room.
Commercial Duct Cleaning
Commercial buildings in San Pedro, from restaurants on 6th Street to offices near the ferry terminal, deal with the same port-sourced particulate load as homes, plus kitchen exhaust and foot-traffic debris. We schedule commercial work around your operating hours and provide the same written price and photo record we give residential customers. In commercial spaces with rooftop units, we also inspect intake locations, since port corridor buildings often pull in truck exhaust from nearby loading zones.
Supply Duct Cleaning
Supply ducts are what deliver conditioned air to your rooms. In San Pedro, supply runs near windows and exterior walls pull in salt-laden air that accelerates grille corrosion. We clean supply runs with a rotating brush system paired with negative pressure, then inspect every register. When we find grilles rusted through from harbor air, we say so and show you the photo. Replacement registers are priced on the written scope before any work proceeds.
Return Duct Cleaning
Return ducts pull air back to the system. In San Pedro’s 1920s-1940s homes, return runs were often built as open cavities between wall studs or floor joists, not sealed metal ducts. Over decades, these cavities collect debris, bypass air, and leak. We camera-inspect every return before touching it. If a return is disconnected under the crawl space, we photograph it, show you, and quote the sealing repair separately under Haven Standard Clause 1: a written price before work starts.

BeforeAfterTrusted Brands We Service in San Pedro
San Pedro homes carry a mix of equipment: original gravity furnaces, retrofitted forced-air units, and newer high-efficiency systems. We service and clean all of them, and our tool set includes professional-grade equipment from Abatement Technologies, Honeywell, and Nikro. Those are brands you can look up independently. If your system uses Honeywell media filters or an Aprilaire cabinet, we can replace the media during the same visit. Full System Cleaning and Video Inspection are standard inclusions on every job, not optional upsells.
Common Air Duct Cleaning Problems We See in San Pedro Homes
- Port soot coating on supply runs. Homes south of Gaffey Street and east of the 110 accumulate a black-gray diesel film inside supply ducts that absent a few miles north. This is direct port emissions, and it requires HEPA-filtered negative-pressure removal, not a brush-only pass.
- Disconnected return ducts in crawl spaces. In 1920s and 1930s bungalows and Foursquares, original gravity-era return runs often separate at the joints. Air bypasses the filter and pulls directly from the crawl space. We find this on roughly one in three older San Pedro homes we inspect.
- Rusted register grilles from salt air. The constant onshore marine flow carries salt that eats through sheet-metal grilles faster than in inland cities like Carson or Lakewood. Replacing grilles is a small line item, but it matters for airflow.
- Post-clean re-coating within months. Homes near the port that keep standard fiberglass filters see fresh soot build-up within six to twelve months. We recommend MERV 13 filters in San Pedro, and we explain why on the written scope.
Pricing for Air Duct Cleaning in San Pedro, CA
For a single-system San Pedro home, expect $425-$780 depending on square footage, number of runs, and whether the ducts have been cleaned in the past decade. A two-story home or one with a second return plenum runs toward the higher end. Video inspection is included in the base price, not billed separately. Our price includes every supply and return run, both plenums, the blower compartment, and the full photo record. If we find a disconnected return under the crawl space, we photograph it and quote the sealing repair as a separate written line item before any extra work begins. That is the whole point of Haven Standard Clause 1: one written price, agreed to before the truck door rolls up.

FAQs - Air Duct Cleaning in San Pedro
That coating is diesel particulate from the Port of Los Angeles. San Pedro sits directly adjacent to the busiest container port in the Western Hemisphere, and the continuous truck and ship emissions settle into residential HVAC systems through outside air intakes and negative pressure zones around windows and doors. In Torrance, you are several miles from the port and prevailing winds push most of that particulate inland toward the 110 corridor, not across the South Bay.
Most homes near the port should be cleaned every 2 to 3 years instead of the 3 to 5 year interval common elsewhere in Los Angeles. The distinguishing factor is the volume of diesel soot entering the system, not the amount of household dust. In Vista del Oro and the hillside streets above Western Avenue, the interval can stretch to 3 to 4 years because elevation and distance from the terminals reduce the particulate load. Call (806) 606-6902 for an assessment based on your specific street.
Yes. Gravity-era duct systems from the 1920s-1940s were built without the sealed metal runs of modern forced-air systems, and in San Pedro they frequently include open cavities, disconnected sections, and collapsed returns under crawl spaces. We camera-inspect every run first, then clean with negative-pressure equipment sized for the job. Brushing alone is not enough on these systems and can push debris further into wall cavities if a return is already compromised.
Yes. The salt-laden marine layer that sits over San Pedro for much of the year accelerates corrosion on sheet-metal ducts and register grilles, especially in homes within a half-mile of the water. You may see rust on grilles before you see soot. During a clean, we look for thinned duct walls and rust-through, photograph them, and note them on your written record so you can plan for repair rather than discovering a failure mid-season. Call (806) 606-6902 to schedule an inspection.
Cleaning removes what is already inside. It does not stop new particulate from entering. In San Pedro, we routinely recommend upgrading to MERV 13 media filters after a clean, because the port emissions do not stop and a standard fiberglass filter lets most of that particulate pass straight through. Your written quote will include a filter recommendation specific to your system, and the cost is listed line by line before you approve anything.
What We Actually Find Under San Pedro Homes
On a 1930s California Foursquare in Barton Hill, our tech pulled a disconnected 6-foot section of original gravity-era return duct under the crawl space. The homeowner had paid another company to clean the ducts two years earlier. That crew cleaned the supply registers and skipped the crawl space entirely. We removed the debris with negative pressure and HEPA filtration, camera-inspected every run, sealed the disconnects with water-based mastic, and upgraded the supply registers to MERV 13 so port soot stopped re-entering the living space. The photo record from that job showed exactly what the previous company missed. That’s the difference between cleaning registers and cleaning a system.
Video inspection is part of every CleanRun job in San Pedro. We do not clean blindly. When the camera shows a collapsed return, a rusted plenum, or a disconnected run, we show you the image and explain the fix in plain language. The repair is quoted separately, in writing, before any extra work proceeds. Our Air Duct Cleaning process is documented at every step, from the first register pull to the final after-photo.
