We’re familiar with every corner of this fog-bound city, from the Linda Mar tract homes off Highway 1 to the hillside ranches above Fairway Park and the mid-century builds tucked along Palmetto Avenue. Pacifica’s persistent marine layer isn’t a seasonal visitor, it’s a year-round condition. That changes everything about how ductwork fails here, and how it must be cleaned. Our Air Duct Cleaning team arrives with equipment and methods built for biological contamination, not just dust.
Most Pacifica calls reach us within 30 minutes by phone, and we schedule service across 94044 within one to three business days. Emergency calls for blocked dryer vents or visible mold in registers get same-day priority. We’ve been driving these coastal roads for over 42 years. We know the traffic patterns, the hillside access issues, and which crawl spaces flood after a heavy fog week.
Why Bellows Air Duct & Vent Co. Is Pacifica’s Preferred Air Duct Cleaning Company
Pacifica homeowners don’t call us for flashy trucks or coupon gimmicks. They call because their neighbor called, or because they got burned once by a low-bid operator who vacuumed the registers and called it done. Our reputation here is built on showing the problem before we fix it, and proving the fix after.
We answer the phone 24 hours a day with a live person, not an app or voicemail tree. Our technicians are background-checked, uniformed, and trained specifically on Pacifica’s moisture-driven failure modes. The 90-Day Done Right Promise covers every job in Pacifica, no paperwork required. If something’s not right, we return and make it right.
Ray Castillo, who leads Bellows Air Duct & Vent Co., set the standard in 1984: one honest price shown before work starts, camera-verified results every time. That standard hasn’t changed. We’ve cleaned ducts on Royal Drive in Linda Mar, on Oddstad Boulevard, and in the Fairway Park homes where original 1960s systems still struggle against the marine layer.
Our Air Duct Cleaning Services in Pacifica
Residential Duct Cleaning
Pacifica’s housing stock demands a specific approach. The post-WWII tract construction that dominates Linda Mar and Fairway Park was built with sheet-metal ductwork run through crawl spaces that sit inches above saturated coastal soil. Decades of fog exposure have left many systems with corroded joints and deteriorating insulation. Our residential cleaning starts with a video inspection to document the actual condition, then uses HEPA-contained equipment to remove biological contamination without spreading spores through the house. Most Pacifica homes need this service every two to three years, not the five-year interval that works inland.
Commercial Duct Cleaning
Pacifica’s commercial buildings face the same marine saturation as residences, often with worse consequences because HVAC systems run longer hours. Restaurants along Rockaway Beach Avenue, medical offices near Palmetto, and retail spaces in Linda Mar Shopping Center have all called us for duct contamination that standard maintenance missed. We schedule commercial work to minimize disruption, and our camera inspection provides documentation for insurance or health department requirements.
Supply Duct Cleaning
Supply ducts push conditioned air into your living spaces. In Pacifica, they’re often the first place homeowners notice mold staining around registers, or that persistent musty smell that no air freshener fixes. We clean supply lines with rotary brushes and negative-air HEPA collection, then verify with camera inspection that the contamination is removed, not just disturbed. This matters especially in Pacifica’s older homes, where decades of fog moisture have created layered biological growth that superficial cleaning reactivates within weeks.
Return Duct Cleaning
Return ducts pull air back to the HVAC unit, and in Pacifica they often serve as the primary entry point for fog-laden outside air when crawl space joints fail. A return duct pulling unconditioned marine air forces your system to work harder, runs up energy bills, and introduces moisture that feeds mold throughout the system. Our return duct cleaning includes sealing accessible joints with mastic, not tape, to stop the infiltration at its source.
Full System Cleaning
For Pacifica homes with compounded moisture problems, we recommend full system cleaning: supply and return ducts, trunk lines, plenum, and HVAC cabinet. This is the service that addresses the root cause in fog-saturated environments. We use Rotobrush systems with HEPA containment, seal corroded joints, and provide before-and-after video documentation. Most full system cleans in Pacifica run $650-$1,200 depending on system size and contamination level.
Video Inspection
Every job we do in Pacifica starts and ends with camera inspection. Not as an upsell, but as proof. Homeowners here have heard empty claims before. Our video inspection shows you the corroded joint, the composted insulation, the mold colony, before we touch anything. Then we show you the clean duct, the sealed seam, the dry surface after we’re done. The video belongs to you. We keep copies for our records, but you get the file.

Trusted Brands We Service in Pacifica
Bellows technicians carry professional-grade equipment from Nikro, Honeywell, and Abatement Technologies, the same brands serious HVAC contractors specify for contamination remediation. For Pacifica homeowners, this means we don’t need to order parts or rent equipment when we find your problem. Our trucks stock HEPA vacuums, rotary brush systems, and mastic sealant for corroded joints. If your system includes Aprilaire media filters or Honeywell electronic air cleaners, we service those components during the same visit. Fast turnaround matters when you’re living with mold in your air.
Common Air Duct Cleaning Problems We See in Pacifica Homes
- Composted duct insulation. In Pacifica’s 1950s-70s tract homes, original sheet-metal ducts in crawl spaces often have insulation that has absorbed so much coastal moisture it has composted around the duct, a failure mode almost never seen in drier inland San Mateo County towns. This material blocks airflow, breeds mold, and continually reintroduces moisture into the system even after surface cleaning.
- Corroded sheet-metal joints pulling in fog air. Decades of marine exposure eat through original duct seams in crawl spaces. The resulting gaps draw persistent fog-laden outside air directly into your HVAC system, causing condensation on duct walls and creating ideal conditions for microbial growth that no register cleaning can address.
- Improper cleaning that reactivates mold. Discount operators often disturb settled mold spores without sealing the duct afterward. In Pacifica’s chronic dampness, those spores rehydrate within days and colonize fresh surfaces. We see this repeatedly in Linda Mar homes where homeowners paid for “cleaning” that made the problem worse.
- Blocked dryer vents compounded by moisture. Pacifica’s fog moisture makes lint clump and stick in dryer vent lines, creating fire hazards and forcing dryers to run longer. We clean these lines with rotary tools and verify airflow restoration, not just visual clearance.

FAQs - Air Duct Cleaning in Pacifica
Because it essentially is compost. Pacifica’s chronic coastal fog keeps crawl spaces damp year-round, and the fiberglass or early-cellulose insulation wrapped around your 1960s sheet-metal ducts has absorbed decades of moisture, rotted, and broken down into organic matter that breeds mold and blocks airflow. This is not normal wear, it’s a Pacifica-specific failure mode caused by marine saturation that inland ducts never experience. Call (844) 685-6342 and we’ll show you on camera exactly what’s happening in your crawl space, estimates are free.
Every two to three years for most Pacifica homes, compared to five years in drier climates. The persistent marine layer here means moisture, not just dust, drives contamination. Homes in Linda Mar and Fairway Park with original ductwork may need annual inspection to catch corroded joints before they become mold pathways. Our $89 Seasonal Tune-Up includes a look inside with the camera so you know where you stand.
No, not if the moisture source isn’t addressed. Standard dust removal disturbs mold without sealing the duct, and in Pacifica’s fog-saturated environment, spores reactivate within weeks. We use HEPA-contained rotary cleaning plus mastic sealing of corroded joints to stop the moisture infiltration that feeds the mold. Our full system cleaning includes this moisture-focused approach, not generic vacuuming.
Yes, regularly. We crawled under a Linda Mar ranch house on Royal Drive and found duct insulation that looked and felt like wet peat moss; the original 1960s sheet-metal joints were so corroded they were pulling fog-laden outside air into the system. We used a Rotobrush with a HEPA vacuum to clear the mold colonies and sealed every seam with mastic, preventing the composted insulation from continually feeding moisture into the living space. Most Pacifica crawl spaces are tight but accessible with proper equipment.
We use Nikro HEPA vacuum systems and Rotobrush rotary cleaning equipment for physical removal of contaminated material, and Abatement Technologies containment systems to prevent cross-contamination during the job. For filtration upgrades after cleaning, we install Honeywell and Aprilaire media filters sized to your system. These are the brands HVAC contractors specify for remediation work, not consumer-grade tools.
