We’ve been driving the Coast Highway to Pacifica since 1984. Roger Castañeda and our team know this city’s fog-bound neighborhoods well: the post-war tracts of Pacific Manor, the hillside homes in Vallemar, the ranch-style houses tucked into Linda Mar’s valleys. Pacifica’s not like San Bruno or Millbrae. The marine layer sits here. That changes what happens inside your ducts.
Why Bellows Air Duct & Vent Co. of California Is Pacifica’s Preferred HVAC Cleaning Company
Pacifica homeowners call us back because we show them the problem before we quote a price, and we show them the fix before we leave. Our camera inspection records every job: the corroded register in your Sharp Park hallway, the mold bloom in your Linda Mar crawl space, the salt-damaged connection in your Pacific Manor attic. You see it. We see it. No one argues later.
Our phone rings at the office 24 hours a day, answered by a live person. Not a menu. Not an app. If your furnace blower smells like mildew at 10 p.m. on a foggy Tuesday, someone picks up and schedules you.
Most Pacifica jobs finish in one visit. Our technicians are background-checked, uniformed, and carry Rotobrush and Nikro equipment sized for residential ductwork. The price we quote on the phone is the price on the invoice. We’ve operated this way for 42 years.
Our 90-Day Done Right Promise applies to every Pacifica home we enter: if the work isn’t right, we return at no charge. No paperwork. No arguing. Roger Castañeda put that in writing when he founded the company, and it hasn’t changed.
Our HVAC Cleaning Services in Pacifica
Evaporator Coil Cleaning
The evaporator coil in your Pacifica air handler lives in darkness and 85% relative humidity for months at a stretch. That is mold’s preferred environment. We remove the coil assembly, clean it with foaming agent and low-pressure rinse, and treat it with an antimicrobial coating that resists regrowth in damp conditions. A typical evaporator coil cleaning in Pacifica runs $180-$340. Most homeowners in Linda Mar and Vallemar need this every 18-24 months, not the 3-5 year interval that suffices inland.
Blower Cleaning
Your blower motor and wheel move every cubic foot of air your home breathes. In Pacifica, that air carries salt particles and moisture that cake onto blower blades, throwing the wheel out of balance and straining the motor bearings. We remove the blower assembly, clean each blade, lubricate sealed bearings where accessible, and reassemble with the wheel balanced to factory spec. Blower cleaning in Pacifica typically costs $150-$280. We find this service especially necessary in Pacific Manor homes where the original 1960s furnaces still run with blowers that have never been removed for cleaning.
Condenser Cleaning
Pacifica’s salt air corrodes condenser fins and coats them with a film that blocks heat transfer. Your AC works harder, draws more power, and fails sooner. We wash the condenser coils with foaming cleaner, straighten damaged fins with a comb tool, and inspect the electrical connections for salt-induced corrosion. Condenser cleaning runs $120-$220 in Pacifica. For homes near Highway 1 or the bluffs above Rockaway Beach, we recommend annual service.
Air Handler Cleaning
The air handler is the heart of your duct system: blower, coil, drain pan, and filter rack in one cabinet. In Pacifica’s climate, the drain pan and cabinet interior grow biological film that circulates through your home every time the fan runs. We disassemble accessible panels, clean and treat all interior surfaces, clear the condensate drain line, and verify proper slope so water exits rather than pools. Air handler cleaning in Pacifica ranges from $220-$400 depending on accessibility and condition. This is the service that most often reveals hidden mold in Pacifica homes, particularly in Vallemar hillside properties where the unit sits in a damp basement or garage.
Heat Exchanger Cleaning
Gas furnace heat exchangers in Pacifica suffer from the same salt-air corrosion that attacks outdoor equipment, plus the added stress of condensation from short heating cycles. We inspect with a borescope camera, clean accessible surfaces, and document condition for your records. Heat exchanger cleaning runs $200-$380. If we find cracks or corrosion penetration, we stop and show you before proceeding.
Coil Treatment
After cleaning, we offer an antimicrobial coil treatment using EPA-registered products compatible with your system’s materials. In Pacifica’s persistent humidity, this treatment extends clean intervals by 30-50% compared to untreated coils. Coil treatment adds $45-$85 to any cleaning service.

Trusted Brands We Service in Pacifica
We clean and maintain equipment from every major manufacturer, and we stock common parts for faster turnaround on Pacifica service calls. Our vans carry Rotobrush duct cleaning machines, Nikro HEPA vacuums, and antimicrobial treatments from Abatement Technologies. For air quality upgrades, we install Honeywell and Aprilaire UV purifiers and media filters. When we find a Pacifica home with original ductwork from the 1950s or 1960s, we have the fittings and adapters to connect modern equipment without forcing mismatched parts.
Common HVAC Cleaning Problems We See in Pacifica Homes
- Corroded metal duct connections and registers. Salt-laden coastal air attacks exposed metal surfaces year-round. We regularly find register screws frozen in place and duct seams rusted through in Pacifica homes within sight of the ocean, particularly in the 94044 zip code along the Palmetto Avenue corridor.
- Chronically damp duct interiors that never dry. Pacifica’s marine layer suppresses temperatures so effectively that furnaces run briefly and rarely. Duct surfaces stay damp for weeks, allowing mold and mildew to establish colonies that would dry out and die in San Bruno’s warmer, drier climate.
- Collapsed flexible ducting in crawl spaces. In hillside and valley-bottom homes in Linda Mar and Vallemar, ground moisture wicks into uninsulated flexible duct runs, softening the liner until it sags and collapses. Homeowners rarely notice because the cool climate means poor airflow still produces adequate temperature at the register.
- Biological buildup in air handlers from condensate pooling. Pacifica’s high humidity overwhelms undersized condensate drains and improperly sloped drain pans. We find slime mold and algae thriving in pans that would stay dry inland, spreading spores through the entire home every cycle.

FAQs - HVAC Cleaning in Pacifica
Pacifica’s persistent marine layer maintains 85-95% relative humidity for much of the year, while inland cities like San Bruno or Millbrae regularly drop below 60%. That moisture infiltrates ductwork through even minor gaps, and because Pacifica’s cool temperatures suppress furnace run times, the dampness never bakes out. Mold colonies establish and persist year-round. If you smell mustiness when your system starts, call (855) 401-6006 for a free camera inspection.
Every 2-3 years for homes in Linda Mar, Pacific Manor, and Sharp Park with original or aging ductwork. The 1950s-1970s sheet-metal and early flexible ducting common in these neighborhoods was never designed for Pacifica’s relentless coastal dampness, and degrades faster than equivalent materials inland. Homes with visible mold history or chronic humidity issues may need annual inspection. We offer $89 seasonal tune-ups that include a quick duct assessment.
Rust on register screws and visible corrosion on metal duct seams are the earliest indicators. You may also notice registers that no longer sit flush as salt-corroded mounting tabs fail, or whistling from new gaps in duct connections. In advanced cases, you’ll feel reduced airflow at distant registers as salt-weakened seams leak into wall cavities. We document all of this with before-and-after camera footage on every Pacifica job.
No. Collapsed flexible ducting with active mold growth requires removal and replacement. Cleaning cannot restore structural integrity to water-damaged liner, and antimicrobial treatments cannot penetrate collapsed sections where air no longer flows. In a Linda Mar hillside home, our crew found flexible duct sections from the original 1960s build partially collapsed and coated in mold, fed by ground moisture wicking through the crawl space. We removed the affected runs, treated the remaining Rotobrush-compatible metal ducts with an antimicrobial sealant, and installed a Honeywell UV air purifier to suppress future growth. Call (855) 401-6006 for an honest assessment of whether your ductwork can be cleaned or needs replacement.
Yes. We deploy Nikro HEPA vacuums with moisture-resistant filters and Rotobrush machines with antimicrobial-compatible brush heads designed for damp duct environments. After cleaning, we apply Abatement Technologies treatments formulated to bond with metal and fiberglass surfaces in high-humidity applications. Standard equipment used by inland cleaners often clogs or underperforms in Pacifica’s conditions. Our technicians also carry humidity meters to verify that treated ductwork has adequate dryness before we seal access panels.
