## Why CleanRun Air Duct Cleaning Is Pacifica’s Preferred Air Duct Cleaning Company

The marine fog that sits over Pacifica most mornings does more than block the view. It keeps indoor relative humidity above 70% for long stretches, and that moisture finds its way into duct systems through separated joints, air handler gaps, and poorly sealed returns. Most companies who come to Pacifica approach this as a dust-accumulation job. That’s the wrong lens. Our Air Duct Cleaning team treats Pacifica as a moisture and biological-contamination problem first. We pull duct sections here and find rust staining, mold colonies, and salt residue that techs from drier inland markets don’t know to look for.

Tomas Reyes founded CleanRun to do one thing the industry wasn’t doing: put everything in writing. Written price before work starts. Photo record of every duct run when the crew leaves. A 365-Day Done Right Promise that’s a written guarantee, not a policy subject to manager approval. That approach resonates with Pacifica homeowners who bought tract houses from the 1950s and 60s and now face original sheet-metal ducts that have spent sixty-plus years in corrosive coastal air.

## Our Air Duct Cleaning Services in Pacifica

### Residential Duct Cleaning

Most Pacifica homes were built out fast in the postwar decades, especially neighborhoods like Linda Mar and Fairway Park. That means aging sheet-metal ductwork, often still original, with joints that have loosened and separated over time. Our residential service covers the complete system: supply ducts, return ducts, the plenum, and the air handler cabinet. We use negative-pressure extraction with HEPA filtration so whatever we dislodge from inside the ductwork does not re-enter your living space. Every register, every run, documented with before and after photos.

### Commercial Duct Cleaning

Businesses along Palmetto Avenue, Coast Highway, and up in the Pedro Point shopping district deal with the same marine-air moisture loading as homes, plus higher occupant density and longer HVAC run cycles. We schedule commercial work with written scopes and fixed pricing per system, not per hour. Building managers get the same photo record and written warranty as residential customers. No separate “commercial pricing” that balloons on site.

### Supply Duct Cleaning

Supply ducts carry conditioned air from the furnace to each room. In Pacifica, supply runs are where we most often find rust staining and biological growth, because the moisture that infiltrates at the air handler gets pushed through these runs first. A Linda Mar ranch home from the 1960s with original metal ducts will typically have salt-laden air moving through separated joints for years. Our techs clean supply runs with agitation tools paired to HEPA-filtered negative pressure, then we camera-inspect to confirm nothing remains before sealing accessible joints.

### Return Duct Cleaning

Return ducts pull air back to the furnace. In Pacifica’s foggy conditions, return runs pick up whatever is pulled in from crawl spaces, garages, and outside air infiltration. We routinely find fiberglass insulation fragments that have been drawn into return ducts through gaps created by rusted metal. Full-system source removal means cleaning both supply and return sides. Clean the supply ducts and skip the returns, and you’ll have contaminated air flowing back to the furnace within weeks. We don’t sell partial jobs as complete.

### Full System Cleaning

This is the service we recommend for nearly every Pacifica home built before 1980. It covers supply and return ducts, the plenum, the blower assembly, the air handler cabinet, and all registers. One flat price per system, written before the first panel comes off. Includes the documented photo record of every run and a written 365-Day Done Right Promise.

### Video Inspection

Some companies in the Bay Area charge extra for camera inspection. We include it as a standard deliverable. Before we start, we scope the system and show you what’s inside: rust, mold, debris depth, joint separation. After we finish, we scope again. You see the difference with your own eyes. That’s evidence, not a sales pitch. If you have a competitor’s quote from another Pacifica duct cleaning company, bring it. We’ll put our written number next to it and show you what’s actually inside your ducts, free of charge. That’s our Free Second Opinion, and it’s never been more useful than on this coast, where rusted 1960s ductwork needs a trained eye to evaluate honestly.

## Trusted Brands We Service in Pacifica

We work on all duct systems regardless of brand, and our equipment roster includes Rotobrush, Nikro, and Abatement Technologies: professional-grade negative-pressure units and HEPA filtration systems you can look up independently before you agree to a price. For Pacifica homes where rust has compromised older metal runs, we stock common replacement sections locally in the Bay Area, which means less waiting when a section needs to be cut out and replaced. If your system uses Honeywell or Aprilaire filtration components, we can service and replace those during the same visit. We name our equipment because you should be able to verify what’s coming into your home. No shop-vac setups, no bait-and-switch equipment claims.

## Common Air Duct Cleaning Problems We See in Pacifica Homes

– Mold colonies inside supply runs from persistent marine fog. Pacifica’s marine layer keeps indoor humidity high year-round. Moisture gets pulled into duct joints and sits there, which is why surface-level brushing without negative pressure simply does not work here. The fog isn’t going away, and neither is the mold unless the source is removed and the system is properly extracted.
– Rusted sheet-metal ducts in Linda Mar and Fairway Park ranch homes. Homes built in the 1950s and 60s along the coast have aged metal that has been exposed to salt-laden air for decades. We routinely pull sections with rust staining on the interior surface and visible corrosion at seams.
– Fiberglass insulation pulled into return ducts through separated joints. When rust opens a gap in a return run, the negative pressure of your furnace pulls insulation from wall cavities and crawl spaces into the airflow. This is extremely common in postwar Pacifica tracts and rarely checked by the average duct cleaning crew.
– Air handler cabinets with biological growth ignored by surface-only companies. Some techs from inland markets will brush the visible duct runs and call it done, completely skipping the air handler cabinet where moisture and mold concentrates. In Pacifica, that’s the difference between a real cleaning and a visit that mostly makes noise.

## Pricing for Air Duct Cleaning in Pacifica, CA

| Service | Typical Pacifica Price Range |
|—|—|
| Full system cleaning (one furnace, up to 12 runs) | $425-$650 |
| Additional furnace/air handler | $150-$250 each |
| Video inspection (before and after) | Included, no extra charge |
| Duct sealing (accessible joints) | $275-$450, quoted in writing before work |
| Dryer vent cleaning (add-on) | $90-$140, often bundled with full system |

The final number depends on system size, number of runs, accessibility, and whether rust damage requires section replacement. But the number is always written down before any work starts. Always. That’s Haven Standard Clause 1, and it exists specifically because this industry is full of $79 coupons that turn into $900 invoices. We don’t do per-vent pricing, we don’t do teaser rates, and we don’t leave until the camera shows clean metal.

## FAQs - Air Duct Cleaning in Pacifica

### How often should air ducts be cleaned in Pacifica’s foggy climate?

Every 3 to 5 years is realistic for most Pacifica homes with original or older ductwork. Homes directly on the coast side, like Sharp Park or Pacifica Manor, where marine fog sits over the house most days, may need cleaning closer to the 3-year mark. Inland Pacifica neighborhoods, like parts of Fairway Park behind the coastal ridge, can often go 4 to 5 years. The deciding factor is moisture: if your indoor humidity runs above 60% during summer and you see visible dust around registers, the system is due. We can assess this during a video inspection and give you a realistic interval based on what we actually see inside your ducts, not a generic recommendation. Call (806) 606-6902.

### Why do Pacifica ducts show more mold than ducts in Daly City?

Because Pacifica takes the marine air directly. Daly City sits behind coastal hills that partially shield it from the persistent salt-laden fog that sits over Pacifica’s valleys. The marine layer drives relative humidity above 70% for long periods each year, and that moisture infiltrates duct systems through separated joints and air handler gaps. In neighboring Daly City, homes of the same vintage rarely show the interior rust staining and mold colonies we see routinely in Pacifica. The difference is geography: Pacifica faces the open Pacific, Daly City gets a filtered version of that air. For an exact written quote, call (806) 606-6902.

### Can rusted metal ducts from the 1950s-60s in Pacifica be cleaned safely?

Yes, but they require the right equipment and a trained eye. On a Linda Mar ranch home with original 1960s sheet-metal ducts, our techs pulled a supply run where rust staining and visible mold colonies lined the interior, the result of decades of salt-laden marine air leaking through separated joints at the air handler. We performed full-system source removal with HEPA-filtered negative pressure, then sealed accessible joints to slow future moisture intrusion. A camera inspection confirmed no biological residue remained in the return ducts. Rusted ducts can be cleaned with agitation and HEPA-filtered extraction, but if sections are severely corroded, replacement is sometimes the only durable solution. We’ll show you the camera evidence and give you a written recommendation either way.

### What is the realistic cleaning interval for rural Pacifica properties with unpaved roads and wood heat?

For properties in the hills above Pacifica, like those off Sharp Park Road heading toward Skyline, or homes on unpaved roads near Pedro Point and Pacifica’s eastern canyons, plan on every 2 to 4 years. Unpaved road dust is finer than typical household dust and gets pulled into duct systems through any minor opening, especially when driving up and down hills creates constant road sediment. Wood heat adds particulate load that accumulates on register faces and inside duct runs, and wood smoke residue is sticky, causing more debris to adhere over time. If you burn wood as a primary heat source and live on a dirt road, inspect annually and clean when the camera shows material build-up at the first elbow. Call (806) 606-6902 for an assessment.

### Does Pacifica’s high humidity affect dryer vent cleaning as well?

Yes, and it’s a bigger problem in Pacifica than most homeowners expect. High-humidity air means dryer exhaust vents don’t dry completely between cycles, allowing lint to clump and stick to duct walls instead of blowing through. Lint that stays damp in a coastal vent creates a real fire risk that builds faster than in drier Bay Area cities. A dryer vent on the coast side of Pacifica should be inspected yearly and cleaned when the lint no longer moves freely, typically every 12 to 18 months. We bundle dryer vent cleaning with full-system work at a reduced rate. Call (806) 606-6902 and we’ll put it in writing.
