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.

AfterFast, Reliable HVAC Cleaning Across Pacifica
HVAC cleaning in Pacifica means dealing with a specific problem: persistent marine fog that keeps indoor humidity high enough for mold to grow inside ductwork year-round. We’ll send a background-checked technician to any Pacifica neighborhood, usually within a day or two of your call. Every job starts with a written price before any panel comes off, and ends with photos of every duct run, inside, before and after. Call (806) 606-6902 and we’ll schedule a time that works.
Pacifica is different from San Bruno or Millbrae. The fog sits in the valleys all day, even through summer, and homes in Linda Mar and Fairway Park were largely built in the 1950s and 1960s with original sheet-metal ductwork. That combination, salt-laden air plus decades-old galvanized steel, creates a moisture and biological-contamination problem that simply doesn’t exist at the same rate five miles inland. We know this because we’ve pulled hundreds of duct sections from Pacifica homes and photographed what’s inside them. The evidence is usually rust staining and visible mold colonies, not dust bunnies. That’s what we’re here to fix.
Why CleanRun Air Duct Cleaning Is the Team Pacifica Homeowners Call for HVAC Cleaning
CleanRun has been documenting HVAC cleaning work since 2013, and over 52,000 homes have gone through our process across the Bay Area. In Pacifica specifically, the homes we see most often are postwar ranch houses in Fairway Park, Linda Mar, and Pedro Point where the ductwork has spent sixty-plus years in a damp, salty environment. Homeowners here tend to research heavily before calling. They want to see a written price, a documented record, and a real name behind the work. That’s exactly what we provide.
Tomas Reyes leads our crews, and he’s the name you’ll see on the paperwork when we arrive. We don’t do vague estimates. Haven Standard Clause 1 is simple: a written price is delivered before any work starts, every time. The written price stays the price. If a competitor has quoted you something, bring it. We’ll put our own number next to it in writing, free of charge.
Our Pacifica customers also get the 365-Day Done Right Promise on every job, in writing. If the work isn’t right, we make it right. That’s not a marketing line. It’s a clause in the job record. And every visit includes a Documented Photo Record of every duct run we touch, so you can see exactly what was inside your system and what it looked like when we finished.
Our HVAC Cleaning Services in Pacifica
Our HVAC Cleaning work in Pacifica focuses on the components that suffer most from coastal humidity: the evaporator coil, the air handler, the blower, and the condenser. Here’s what each one involves and why it matters here.
Evaporator Coil Cleaning
In Pacifica, your evaporator coil is the first place mold takes hold. The coil sits inside the air handler and gets cold when the system runs. Cold surfaces in humid air condense moisture. That moisture never fully dries when the fog keeps indoor humidity at 60 percent or higher. We clean evaporator coils with agitation tools and a cleaning agent designed to break the biological film, not just rinse it. A duct cleaning that skips the coil leaves the system blowing spores right back through the runs you just cleaned.
Air Handler Cleaning
Air handlers in Linda Mar and Fairway Park homes are often original to the house, installed in garages or hallway closets where coastal air moves freely. The blower wheel, housing, and drip pan collect a gray sludge that photographs well and smells worse. We remove the blower assembly, clean the wheel and housing, and treat the interior surfaces. Then we seal any gaps in the air handler cabinet so Pacifica’s damp air stops getting pulled in around the filter.
Condenser Cleaning
The outdoor condenser in Pacifica deals with a different problem: salt. Salt-laden marine air corrodes aluminum fins faster than inland air. A condenser with corroded or clogged fins can’t reject heat properly, which drives up cooling costs even in a city where air conditioning runs only a few weeks a year. We clean the condenser coil, straighten fins where practical, and check the refrigerant lines for corrosion. This is part of a full HVAC clean, not an add-on we’ll spring on you after the fact.
Coil Treatment
After cleaning, we apply a coil treatment that slows biological regrowth on the evaporator and condenser surfaces. This is not a substitute for physical cleaning, and we won’t pretend otherwise. In Pacifica’s humidity, any treatment that claims to prevent mold permanently without removing it first is a fogging upsell. The treatment buys time between cleanings. The cleaning is what actually fixes the problem.

BeforeAfterTrusted Brands We Service in Pacifica
We work on systems from every major manufacturer, and our crews carry professional-grade equipment from Rotobrush and Nikro for source-removal cleaning and negative-pressure extraction. For coil cleaning and air handler work, we use products from Guardsman and Honeywell that homeowners can look up independently before we arrive. We don’t ask you to take our word that the equipment is professional. We name the brands, and you can verify them. When a Pacifica job needs a part, our scheduling team coordinates from our San Francisco Bay Area office and routes the part with the crew. No second trip, no “we’ll be back next week.”
Common HVAC Cleaning Problems We See in Pacifica Homes
- Persistent mold on evaporator coils. The marine layer keeps coils damp from March through August, and biological growth becomes visible on the coil face within a season. A fogging “sanitizer” won’t remove it. Physical cleaning will.
- Rust staining on original 1950s-1960s sheet-metal ducts. Homes in Linda Mar and Fairway Park still run the galvanized ducts installed when the tract was built. Decades of salty air have rusted seams and joints, and the rust itself becomes a surface where mold attaches.
- Leaky air handler cabinets pulling in fog-soaked air. In Pacifica, every gap in the air handler or duct connections is a moisture infiltration point. The system pulls damp garage or closet air around the filter and straight into the supply ducts.
- Short-lived “sanitizing” treatments that regrow mold within weeks. Unless biological growth is physically removed from duct surfaces under negative pressure, it regrows. Rapidly. In Pacifica’s humidity, a chemical fog without removal is a temporary masking job, not a fix.

FAQs - HVAC Cleaning in Pacifica
Because a fog treatment doesn’t remove anything. In Pacifica’s persistent humidity, mold grows on the physical surfaces inside the ductwork, the evaporator coil, and the air handler. A chemical fog can kill surface spores temporarily, but the dead biological material stays put, and the moisture remains. Within weeks, new growth takes hold on the same organic residue. The only effective approach is physical removal: negative-pressure extraction, agitation, HEPA filtration, and then treating the surfaces. Anything less is a temporary patch. If you’ve had a fog treatment and the mold returned, call (806) 606-6902 and we’ll show you what’s actually inside the runs.
Salt air accelerates corrosion. Linda Mar’s original galvanized ducts have spent six decades in a coastal environment where the marine layer sits in the valley all day. The zinc coating on the galvanized steel eventually breaks down, and rust forms at the seams and joints. That rust creates a rough surface where mold attaches more easily. It also weakens the duct walls, which is why we see joint separation and hidden leaks in Linda Mar homes more often than in Fairway Park or Pedro Point. The fix is cleaning, then sealing the joints and gaps so the system stops pulling in more fog-soaked air. Call (806) 606-6902 and we’ll photograph what’s inside your ducts.
Yes. The evaporator coil is the coldest surface in the system, and in Pacifica’s humidity it’s wet nearly year-round. Mold and biofilm develop there first, often before visible growth appears in the duct runs. If the coil is contaminated, the blower pushes spores through clean ducts within days. We photograph the coil before and after on every job, because that’s the evidence that tells you whether your HVAC cleaning was actually complete. A duct-only clean with a dirty coil is half a job. Call (806) 606-6902 for a written estimate that includes the coil.
A negative-pressure clean uses a high-powered vacuum system to create negative air pressure inside the ductwork while agitation tools dislodge debris from the duct walls. The loosened material is pulled directly into the vacuum and captured by HEPA filtration. It doesn’t get blown into the living space. In Pacifica, where the debris is often mold and rust particles rather than ordinary dust, negative pressure matters a lot. We run Rotobrush and Nikro equipment for exactly this reason. Cheaper methods that rely on a shop-vac and a rotating brush don’t capture the fine biological material and often circulate it through the house. Call (806) 606-6902 and ask us to explain the difference before you book.
For homes within a few blocks of the ocean in Pacifica, we recommend a full HVAC cleaning every 18-24 months. Homes in Linda Mar, Pedro Point, and along Palmetto Avenue sit directly in the fog zone, and the evaporator coil and air handler accumulate biological growth faster than homes in Fairway Park or up in the hills. If you’re seeing visible dust on the registers, smelling a musty odor when the system turns on, or noticing that the air feels damp indoors even on clear days, the system is due. Call (806) 606-6902 and we’ll schedule a cleaning at a written price that doesn’t change.
