Fast, Reliable HVAC Cleaning Across Pacifica
HVAC cleaning in Pacifica typically costs $280-$650 for a full system service, with most jobs completed in a single visit. Our HVAC Cleaning team serves Pacifica homeowners with same-day and next-day scheduling, and we answer calls live at (844) 685-6342 around the clock. We’ve worked in Pacifica long enough to know that duct cleaning here is not like duct cleaning anywhere else on the Peninsula. The marine layer that rolls off the Pacific and settles over Linda Mar, Fairway Park, and Sharp Park doesn’t just make for gray afternoons - it saturates crawl spaces, composts duct insulation, and turns aging HVAC systems into mold incubators. If your home was built in the 1950s through 1970s, as most Pacifica housing was, your ductwork is fighting a battle against moisture that inland systems never face.
Ray Castillo and our team at Bellows Air Duct & Vent Co. have been serving Pacifica since the 1980s. We know the original sheet-metal runs under Linda Mar tract homes, the corroded joints that pull in fog-laden air, and the black mold that coats evaporator coils after decades of damp cycling. We don’t guess at what’s wrong. We camera-inspect every system before we quote a price, and we show you what we find.

Our HVAC Cleaning Services in Pacifica
Evaporator Coil Cleaning
In Pacifica, evaporator coil cleaning is often a mold remediation job, not just a dust removal. The chronic dampness in 94044 means coils in air handlers and furnaces accumulate black mold and mildew at rates we rarely see in San Bruno or Millbrae. A typical evaporator coil cleaning in Pacifica runs $180-$340, depending on access and contamination level. We use professional-grade biocidal treatments alongside mechanical cleaning - simple vacuuming won’t touch biological growth that’s been feeding on fog moisture for years. We serviced a 1960s Linda Mar home where the original sheet-metal duct in the crawl space had drawn in fog-laden air through corroded joints; the insulation had turned to soggy compost, and the evaporator coil was coated in black mold. We replaced the compromised duct sections, sealed all connections, and performed a full Rotobrush cleaning with an Abatement Technologies HEPA filtration setup.
Air Handler Cleaning
Pacifica’s air handlers sit in cold, damp environments - garages, crawl spaces, closets - and the marine layer ensures they’re never truly dry. Mold spreads from coils to blower housings to drain pans, and once it’s established, it circulates through every room. Air handler cleaning in Pacifica typically runs $220-$380. We disassemble the housing, clean all components with mold-specific treatments, and verify with camera inspection before we reassemble. For homes in Fairway Park and Sharp Park with original 1960s air handlers, we often find corrosion on the blower wheel itself - another failure mode the fog creates.
Coil Treatment
After cleaning, we apply a protective coil treatment that inhibits mold regrowth in Pacifica’s saturated environment. This isn’t an upsell - it’s a necessity here. Coil treatment adds $45-$85 to the service, and for Pacifica homes, we recommend it on every clean. The treatment we use is formulated for high-moisture coastal zones, not the dry-heat conditions most products are designed for. Without it, we’ve seen coils re-contaminate within a single fog season.
Blower Cleaning
The blower motor and wheel are the engine of your airflow. In Pacifica, damp conditions cause dust to adhere with moisture, creating a paste that imbalances the wheel and strains the motor. Blower cleaning runs $160-$290 in Pacifica. We remove the assembly, clean the wheel and motor housing, test amperage draw, and re-balance before reinstalling. A clean blower uses less energy and moves air the way the system was designed to.
Condenser Cleaning
Outdoor condensers in Pacifica face salt air corrosion that inland systems never see. While the fog keeps temperatures moderate, the salt accelerates fin deterioration and electrical contact corrosion. Condenser cleaning runs $140-$240. We clean coils, check electrical connections for corrosion, and verify refrigerant pressures. For Sharp Park homes near the coast, this service is particularly critical.
Heat Exchanger Cleaning
Older Pacifica furnaces with heat exchangers need inspection for corrosion pinholes caused by decades of damp combustion air. Cleaning and inspection runs $180-$320. If we find compromise, we’ll show you on camera and discuss repair or replacement options with upfront pricing.

Trusted Brands We Service in Pacifica
We clean and service systems built with Rotobrush, Abatement Technologies, and Nikro equipment - the same brands serious HVAC contractors specify for coastal environments. We stock parts and treatments suited to Pacifica’s moisture conditions, not generic supplies meant for dry climates. That means faster turnaround for Pacifica homeowners and repairs that hold up against the marine layer. Our technicians carry HEPA filtration setups from Abatement Technologies on every Pacifica job, because standard vacuums recirculate mold spores in damp ductwork.
Common HVAC Cleaning Problems We See in Pacifica Homes
- Corroded sheet-metal joints in original 1950s-70s ductwork. The fog-laden air drawn through gaps in crawl-space ducts creates persistent mold colonies that simple cleaning can’t solve without sealing the leaks first. We see this in Linda Mar and Fairway Park on nearly every older home call.
- Composted duct insulation. Technicians working crawl spaces under 1960s Linda Mar tract homes regularly find duct insulation that has absorbed so much fog moisture it has essentially composted around the duct - a failure mode rarely seen in Daly City just four miles north, and almost unheard of in inland San Mateo County towns.
- Mold-heavy evaporator and blower components. Pacifica’s chronic marine dampness causes HVAC blower and evaporator coils to accumulate mold and mildew far faster than dust-based systems, requiring biocidal cleaning treatments rather than simple vacuuming.
- Poorly sealed connections actively drawing outside air. Decades of marine-air exposure have left many aging systems with deteriorating duct insulation and poorly sealed connections that pull in fog-laden outside air 24 hours a day, undoing any cleaning within months.

FAQs - HVAC Cleaning in Pacifica
Pacifica’s persistent marine layer traps fog against the coastal hills longer than any neighboring city, keeping crawl spaces and ductwork in cold, damp conditions year-round. South San Francisco sits slightly inland with more burn-off; your system never dries out. The solution is sealing duct leaks first, then cleaning with biocidal treatments designed for moisture-driven mold - not standard dust removal. Call (844) 685-6342 and we’ll camera-inspect to show you exactly where the moisture enters.
Most Pacifica homeowners need full HVAC cleaning every 2-3 years, not the 4-5 year interval that works inland. If your home has original 1960s ductwork in a crawl space, annual inspection is wise - the fog doesn’t take a season off. We offer an $89 seasonal tune-up that catches problems before they require major service. Call (844) 685-6342 to schedule.
If your insulation has absorbed enough fog moisture to compress, discolor, or separate from the duct, replacement is necessary - cleaning alone won’t fix composted insulation. We see this in roughly half the Linda Mar crawl spaces we enter. Camera inspection reveals the condition without guesswork. Replacement typically adds $400-$900 to the service, and we only recommend it when we can show you the damage. Call (844) 685-6342 for a free inspection.
Mechanical agitation with a Rotobrush system, combined with Abatement Technologies HEPA containment and biocidal treatment, outperforms vacuum-only methods in Pacifica’s moisture-driven contamination. The brush dislodges mold adhering to damp metal; the HEPA system captures spores instead of recirculating them; the biocide inhibits regrowth through the fog season. We adjust the protocol based on what your camera inspection shows. Call (844) 685-6342 to discuss your system.
Yes. We work in Pacifica crawl spaces year-round, and our equipment is built for damp conditions. The fog doesn’t stop service - in fact, winter is when many homeowners notice the musty smell that signals mold activity. We contain our work area, run dehumidification as needed, and verify dryness before we seal. Same-day scheduling is often available. Call (844) 685-6342.
