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 HVAC Cleaning Across San Pedro
HVAC cleaning in San Pedro means removing more than household dust. It means pulling decades of Port of Los Angeles diesel soot, salt corrosion, and marine-layer humidity out of ductwork in homes built between the 1920s and 1960s. CleanRun Air Duct Cleaning handles the full system: evaporator coil, blower, condenser, air handler, and the duct runs connecting them. We document everything with before-and-after photos of every run, and we hand you a written price before a single panel comes off. Call (806) 606-6902 to schedule.
Why CleanRun Air Duct Cleaning Is San Pedro’s Preferred HVAC Cleaning Company
San Pedro’s housing stock is unlike anywhere else in Los Angeles County. Craftsman bungalows off Barton Hill, California Foursquares near downtown, and post-WWII tract homes above the harbor all share one thing: original or first-generation ductwork still moving air through rooms built 70 to 100 years ago. Our HVAC Cleaning team has worked these systems enough to know what we’re going to find before the camera goes in. Port soot packed into the plenum. Salt-corroded register grilles. Disconnected return runs pulling crawlspace air into living spaces.
Tomas Reyes, who leads CleanRun, set the standard early: every San Pedro job gets a written price before work starts, and every duct run gets photographed before and after. No exceptions. That’s Haven Standard Clause 1. It’s why homeowners in San Pedro who research before they call end up calling us.
We coordinate dispatch from our Los Angeles office, and crews serve San Pedro locally. Technicians arrive background-checked, uniformed, and identified by name before they walk up the driveway.
Our HVAC Cleaning Services in San Pedro
HVAC cleaning is not one service. It’s five or six distinct jobs, each of which fails differently in San Pedro’s coastal, port-adjacent air. Here’s what we actually do when we clean a system here.
Evaporator Coil Cleaning
The evaporator coil sits inside the air handler and is the first place San Pedro’s diesel soot settles. Because port emissions carry fine particulates that standard fiberglass filters don’t catch, the coil packs tight with a black-gray film that kills airflow and freezes the AC by midsummer. Evaporator coil cleaning in San Pedro typically runs $280-$480. We use coil-safe agitation and pressure washing, not just spray-on foams that leave residue behind.
Blower Cleaning
A blower motor caked with soot and salt dust draws more amps, runs hotter, and fails years early. In homes near Gaffey Street and the harbor, we routinely find blower wheels so coated that the fan is off-balance. Blower cleaning in San Pedro runs $180-$320, including removal, cleaning of the wheel and housing, and reinstallation. If the motor bearings are worn, we document it with photos and hand you a written recommendation before touching anything.
Condenser Cleaning
The outdoor condenser is where San Pedro’s salt air does its visible work. Coil fins corrode, get coated in harbor spray, and lose the ability to reject heat. Condenser cleaning here runs $180-$300. We clean the coil, straighten bent fins, and check the refrigerant lines the same visit. In hillside homes above Western Avenue, we also pull leaves and debris that collect under the unit where coastal wind piles them.
Air Handler Cleaning
The air handler is the box that houses the blower, coil, and often the filter. In San Pedro’s older homes, air handlers are frequently located in crawlspaces or attics that have never been airtight. That means the air handler is constantly ingesting damp, particulate-laden air. Air handler cleaning in San Pedro runs $350-$650 depending on access and how much disassembly is required. We clean the interior cabinet, the condensate pan, the drain line, and the coil, then photograph the result through every access panel.

BeforeAfterTrusted Brands We Service in San Pedro
We work on systems from every major brand installed across San Pedro: Carrier, Trane, Lennox, Goodman, Rheem, and older Day & Night units still running in postwar tract homes. For cleaning, we use Rotobrush agitation systems, Nikro negative-air machines, and Guardsman antimicrobial coil treatments. If your air handler takes a Honeywell filter assembly, we can source the replacement same day. You don’t need a single brand of equipment to get a proper cleaning, but you should know what’s being used before it goes into your ducts. We name our equipment on every written scope.
Common HVAC Cleaning Problems We See in San Pedro Homes
- Port soot bypassing standard filters. The diesel particulate from port terminals near Barton Hill packs the evaporator coil and blower wheel. Cleaning without upgrading filtration means the problem returns within a season.
- Salt-corroded sheet-metal seams. Decades of onshore salt air eats the seams on older duct runs, especially in crawlspaces. Disconnected runs pull unfiltered, damp air straight into the supply side. A camera inspection is the only way to find these.
- Marine-layer mold substrate. San Pedro’s persistent humidity turns old dust and soot inside gravity-era ducts into a damp layer where mold develops. Cleaning alone doesn’t fix it. The ducts need sealing afterward, or the mold comes back.
- Crushed or disconnected gravity-era returns. Original ductwork from the 1920s and 1930s often runs through crawlspaces that shifted over the decades. Crushed returns pull air from under the house, not from the rooms. We find this on most older Craftsman cleanings.
Pricing for HVAC Cleaning in San Pedro, CA
Whole-system HVAC Cleaning in San Pedro typically runs $700-$1,400, depending on system size, number of duct runs, and access. That’s one flat price per system, agreed before work starts. No per-vent pricing that multiplies unexpectedly. Evaporator coil cleaning alone runs $280-$480. Blower cleaning $180-$320. Air handler cleaning $350-$650. If your ducts need sealing after the clean, that’s priced separately and in writing before we do it. The written quote is the contract. A home near the port with 10-12 runs and a crawlspace air handler will land on the higher end. A hillside home with a garage-mounted handler and newer ductwork lands lower. Call (806) 606-6902 for a detailed written quote, or bring us a competitor’s estimate and we’ll put our number next to it in writing, free.

FAQs - HVAC Cleaning in San Pedro
That coating is diesel soot from Port of Los Angeles operations. San Pedro sits immediately adjacent to the busiest container port in the Western Hemisphere, and fine diesel particulate drifts into homes near Barton Hill, downtown, and anywhere downwind of the terminals. A few miles north in Harbor City or east in Wilmington, the same coating doesn’t appear at anywhere near the same density. Standard fiberglass filters don’t catch these particles. They pass through, enter the duct system, and deposit on the first surface they hit: the supply ducts and evaporator coil. This is a port-pollution removal job, not a household-dust cleaning. Call (806) 606-6902 to schedule a camera inspection and written quote.
Every 2 to 3 years for homes within a mile of the port terminals; every 4 to 5 years for hillside homes above Western Avenue. The difference is particulate load. Homes near the harbor ingest constant diesel soot, and the evaporator coil and blower pack significantly faster. Hillside homes deal more with salt air corrosion and marine-layer humidity than soot volume, so the cleaning interval stretches, but sealing work matters more up there. We’ll give you a written recommendation based on what the camera shows, not a calendar.
Yes. Salt-laden onshore airflow accelerates corrosion on sheet-metal duct seams, register grilles, air handler cabinets, and blower components. We regularly see blower wheels pitted and off-balance in homes that have never had the system opened. The corrosion is worse in crawlspace-mounted air handlers where damp air sits year-round. During a blower cleaning, we inspect for bearing wear and shaft corrosion, photograph anything questionable, and put the fix in writing before recommending it.
Cleaning removes the material that’s causing the smell, but if mold has developed inside the duct lining or on the coil, cleaning alone won’t stop it. The marine layer keeps humidity inside ductwork high enough that mold can colonize the accumulated port dust and debris. We clean with negative-pressure extraction and agitation, then assess whether antimicrobial treatment is warranted. If it is, we use Guardsman coil treatment and document before-and-after photos of the affected surfaces. The honest answer is that sealing the ducts after cleaning is what prevents the smell from returning. We price that separately and in writing.
MERV 13. San Pedro’s port emissions don’t stop after the ducts are clean, and a MERV 13 filter catches the fine particulates that standard fiberglass filters miss. The tradeoff is airflow: older systems with undersized returns may not handle MERV 13 without static pressure rising, so we check the system before recommending the upgrade. In most San Pedro homes, especially those near the harbor, upgrading to MERV 13 is the single most effective thing you can do after a cleaning to keep the coil and blower from packing again. We stock Honeywell MERV 13 filters and can have them installed the same visit.
What We Actually Found in a San Pedro Home
Working a 1920s Craftsman off Barton Hill, our tech found the original gravity-era ducts coated in port soot and a disconnected return run pulling unfiltered air from the crawlspace. We used negative pressure and a Rotobrush agitation system per NADCA standards, then sealed the return and upgraded the homeowner to a MERV 13 filter. The air handler finally stopped grinding on salt-corroded blower wheels. That’s the difference between cleaning what you can see and cleaning what’s actually failing.
