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.
Fast, Reliable Air Duct Cleaning Across Pacifica
Most homes in Pacifica run between $380 and $620 for a full residential air duct cleaning, and we put that written price in your hands before a single vent is touched. If your vents smell musty when the furnace kicks on, or you’re seeing dust settle on furniture faster than you can wipe it, your ductwork is likely harboring decades of buildup plus the moisture-driven problems this coast is famous for. Call (469) 972-3151 and a live person will pick up, day or night, to schedule your free estimate.
We’re not strangers to Pacifica. Our crews serve the city from our San Francisco Bay Area office, and we know the difference between a Linda Mar ranch built in 1964 and a hillside home near Pedro Point facing salt spray off the ocean. That local knowledge matters because Pacifica’s chronic marine fog creates duct problems you won’t find in San Bruno or Millbrae. We show up in the arrival window we gave you, run a camera inspection so you see what we see, and leave the written guarantee behind.
Why Kestrel Air Duct Cleaning Is Pacifica’s Preferred Air Duct Cleaning Company
Pacifica homeowners call us after they’ve been burned by the bait-and-switch routine: a coupon price that balloons once the truck is in the driveway. We don’t operate that way. The Kingswell Guarantee, which has governed every job since 2004, requires a written price before work begins, a defined arrival window, a clean job site, and a written guarantee with a free return visit if the work fails. Dale Whitmore and our Air Duct Cleaning team stand behind that standard on every Pacifica visit.
Our technicians are background-checked, uniformed, and trained on professional-grade equipment: Rotobrush rotary brush systems that physically dislodge debris at the duct wall, Nikro negative-pressure units that pull loosened contaminants out of the system, and Abatement Technologies HEPA filtration that keeps those particles out of your living space during cleaning. These aren’t box-store shop vacs. When we finish a job in Vallemar or Sharp Park, we show before-and-after photos of your own ducts, not stock images.
Calls are answered by a live person, 24/7. No voicemail maze. No automated queue. A real conversation, whether you’re calling at 7 a.m. before work or 9 p.m. after noticing that musty smell again.
HVAC Duct Cleaning in Pacifica
HVAC Duct Cleaning in Pacifica means more than pushing a brush through a tube. The marine layer that blankets this city nearly year-round drives moisture into crawl spaces and attics where your ductwork lives, creating conditions we simply don’t encounter in drier inland markets. We inspect the full system, agitate debris with rotary brushes under controlled negative-air extraction, then remove it with HEPA-filtered collection. For most Pacifica homes, this runs $380-$620 depending on system size and accessibility.
Our crews find the real problems while we’re in there. Crushed flex-duct runs from the 1960s. Disconnected joints dumping heated air into a mold-friendly crawl space. Salt corrosion weakening metal seams near the coast. We document everything with video, explain what needs cleaning versus what needs sealing, and give you a written price for each before any work proceeds.
Full System Cleaning
A full system cleaning covers supply ducts, return ducts, the main trunk line, and accessible plenum connections. In Pacifica’s post-war housing stock, we often discover that “cleaning” isn’t the full answer. The 1950s-70s flex duct in Linda Mar and Vallemar homes has degraded to the point where agitation would damage it further. We flag this before we start, show you the camera footage, and quote sealing or replacement separately if needed.
Video Inspection
We run a borescope camera through your ducts before and after cleaning. Pacifica homeowners see exactly what the marine humidity has done: mold colonies, dust compaction, crushed runs, corrosion. The “after” footage proves the work, and the documentation supports any warranty claim under our 365-Day Done Right Promise.
Vent Cleaning in Pacifica
Vent Cleaning in Pacifica targets the supply and return registers you see on walls and ceilings, plus the short duct runs behind them that feed into the main system. This is where salt-laden fog does its most visible damage. We remove registers, clean the boots and nearby ductwork with rotary brush agitation, and treat corrosion-damaged metal where we find it. Individual vent cleaning runs $85-$140 per register when done as standalone work, or it’s included in a full system cleaning.
Many Pacifica homeowners start here because the musty smell seems strongest at the vent. Sometimes that’s accurate. Often, though, the odor is circulating from deeper in the system, and vent cleaning alone won’t solve it. We tell you which situation you’re in before we start, not after we’ve run the invoice.
Supply Duct Cleaning
Supply ducts push conditioned air into your rooms. In Pacifica’s hillside homes near Pedro Point, we frequently find supply registers corroded at the collar, letting humid outside air backflow into the system when the fan is off. Cleaning exposes these leaks. We photograph them, quote the seal, and only proceed with your approval.
Return Duct Cleaning
Return ducts pull air back to the handler, and they’re the dustiest part of most systems. Pacifica’s older homes often have undersized return pathways or flex duct that has sagged and pooled debris. Our negative-air extraction pulls this material out without contaminating your living space, and the camera shows you the difference.
Trusted Brands We Service in Pacifica
We clean ductwork connected to every major HVAC brand, and we stock Honeywell and Aprilaire filtration products for Pacifica homeowners who want to maintain cleaner air between service visits. The salt fog here is hard on equipment, so we also carry Guardsman treatments for mold-resistant coating on compromised duct interiors. Most replacement parts for standard registers and collars are on our trucks, which means we can seal corroded joints or swap damaged boots in the same visit rather than scheduling a return trip. For systems needing more extensive remediation, we coordinate with our San Francisco Bay Area office for rapid parts turnaround.
Common Air Duct Cleaning Problems We See in Pacifica Homes
- Active mold colonization with no plumbing leak. Pacifica’s ground-level fog humidity wicks up through uninsulated crawl spaces and into ductwork. We routinely find mold in homes where the owner swears there’s no moisture problem. The moisture is simply the marine layer, doing what it does 300 days a year.
- Crushed or disconnected flex duct from the 1950s-70s. Original ductwork in Linda Mar, Sharp Park, and Vallemar has exceeded its design life. The spiral wire support rusts through, the insulation compresses, and the duct collapses or separates at joints. Conditioned air dumps into the crawl space, energy bills climb, and the remaining connected runs overwork.
- Salt-air corrosion on metal registers and joints. Homes near Pedro Point and Rockaway Beach face accelerated corrosion from ocean-facing exposure. Metal duct collars thin out, screws no longer bite, and humid outside air infiltrates through gaps that didn’t exist five years ago.
- Disconnected returns pulling crawl space air. In Pacifica’s vented crawl spaces, a disconnected return duct doesn’t just leak. It actively draws mold spores, rodent debris, and damp soil air into your breathing space. We find this in roughly one of three older homes we inspect.
Pricing for Air Duct Cleaning in Pacifica, CA
Most Pacifica homes fall between $380 and $620 for a complete residential system cleaning. Smaller condos or partial cleanings can run as low as $280. Larger homes with multiple zones, extensive corrosion damage, or accessibility challenges through tight Pacifica crawl spaces may reach $780-$950. Commercial duct cleaning is quoted per system after inspection.
What moves the price: system size, number of registers, crawl space accessibility (Pacifica’s hillside lots can be tight), whether we find damage requiring sealing or coating, and how long it’s been since the last cleaning. We don’t do per-vent pricing. One flat price per system, agreed in writing, before any work begins. Estimates are free. Call (469) 972-3151 for yours.

FAQs About Air Duct Cleaning in Pacifica
The marine layer keeps Pacifica’s crawl spaces and attics humid year-round, and that moisture wicks directly into uninsulated ductwork. Salt-laden fog penetrates vented crawl spaces even in homes with perfect plumbing, creating sustained humidity levels that support mold growth inside ducts. This is a coastal-specific failure mode we see constantly in Linda Mar and Vallemar, rarely in drier inland zip codes. Call (469) 972-3151 for a camera inspection if you smell mustiness at startup.
Original flex-duct from that era has typically exceeded its 25-30 year design life. We find crushed runs, separated joints, degraded insulation, and active mold in the majority of 1960s Linda Mar homes we inspect. The ductwork is often salvageable with sealing and coating, but it needs professional assessment before cleaning agitation damages it further. We run the camera first and show you exactly what you’re dealing with.
Salt air accelerates corrosion on metal registers, collar screws, and duct joints, weakening seals and creating infiltration paths for humid outside air. We replace corroded hardware with marine-grade alternatives where needed and apply mold-resistant coating to compromised interior surfaces. The damage is progressive, so earlier inspection means simpler, less expensive remediation.
Yes. Our process adheres to NADCA guidelines for source removal: mechanical agitation to dislodge debris, negative-air extraction to contain and remove it, and HEPA filtration to protect indoor air quality during the work. We document compliance with before-and-after video, and our 365-Day Done Right Promise covers any failure of the cleaning standard within the guarantee period.
Cleaning removes accumulated debris and biological growth. Sealing repairs the physical leaks, disconnected joints, and degraded material that let that debris accumulate in the first place. In Pacifica’s aging housing stock, we often find both are necessary: cleaning addresses what’s there now, sealing prevents recurrence and restores system efficiency. We quote each separately after inspection, and you choose what to proceed with. No package pressure. Call (469) 972-3151 to schedule.
