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 Air Duct Cleaning Across San Bruno
Air duct cleaning in San Bruno typically runs $350-$650 for a complete residential system, and our crews schedule most jobs within three to five business days. If you live near Rollingwood, Crestmoor, or the Portola Highlands, you’re already in our regular rotation.
We’re Morton’s Air Duct Cleaning, and we’ve been sending crews through the San Bruno Gap since 2005. Our dispatch office coordinates scheduling from the broader San Francisco Bay Area, but the technicians who arrive at your door know this city’s wind patterns, its post-war housing stock, and why the coastal fog here creates duct problems that inland Peninsula homes simply don’t face. When you call (323) 918-4345, a live person answers - not a voicemail tree, not a chatbot - and we’ll give you a written price before any work starts. Every visit includes shoe covers, drop cloths, and a photo of the clean-up before we leave.
Why Morton’s Air Duct Cleaning Is San Bruno’s Preferred Air Duct Cleaning Company
San Bruno homeowners call us back because we treat the house like it’s our own. Our technicians are background-checked, uniformed, and trained to the Cedarwell C.A.R.E. values - that means quiet tools during nap hours, pet-safe product choices where available, and drop cloths down before the first piece of equipment touches your floor.
We’ve built our reputation on the 365-Day Done Right Promise. If something isn’t right, we make it right. Full stop. No runaround, no “call the office and leave a message.” That promise is stamped on every job, not just offered when you ask.
Our crews know San Bruno’s neighborhoods personally. We’ve cleaned ducts in original 1950s tract homes near El Camino Real where the sheet-metal has started separating at the joints, and in newer Crestmoor rebuilds where the ductwork is pristine but the gap winds still drive debris against the returns. That local knowledge means we spot problems faster and quote more accurately.
Every estimate is free, every price is written, and every invoice matches the price you agreed to. No surprises. No bait-and-switch.
Air Duct Cleaning Services in San Bruno
Air Duct Cleaning Services in San Bruno address a specific set of challenges created by the city’s coastal location at the San Bruno Gap. Our process begins with a video inspection of your full duct run, followed by source removal using professional-grade agitation equipment and HEPA-filtered negative air machines. A typical residential job runs $350-$650 depending on system size and contamination level, with larger homes or commercial properties quoted individually.
We recently worked a 1952 tract home in the Crestmoor neighborhood where the original sheet-metal supply and return ducts were pulling apart at the joints; a camera inspection showed interior liner degradation and a heavy load of grit driven by gap winds against the windward slope. Our tech set up HEPA filtration and negative pressure, used agitation tools to break the debris loose, and sealed the separated joints before we cleared the registers and air handler. The blower motor amp draw dropped noticeably, and the homeowner said the musty smell that had built up over two foggy seasons was gone.
Residential System Cleaning
Our residential clean covers supply ducts, return ducts, trunk lines, and the air handler cabinet. We use Rotobrush mechanical agitation tools to dislodge debris from duct walls, then extract it with Nikro negative air equipment. For San Bruno homes on windward-facing slopes toward San Bruno Mountain, we pay special attention to exterior return-air grilles, where gap winds pack debris against the mesh faster than Peninsula norms.
Video Inspection Before and After
Every full system cleaning includes before-and-after video documentation. You’ll see exactly what was in your ducts, and exactly what we removed. This matters especially in San Bruno’s older housing stock, where 55-75-year-old sheet-metal ductwork may show joint separation or liner degradation that a surface cleaning would miss entirely.

HVAC Duct Cleaning in San Bruno
HVAC Duct Cleaning in San Bruno requires understanding how the city’s unique micro-climate accelerates contamination inside your system. The San Bruno Gap funnels cool, moisture-laden Pacific air through the city at high velocity, creating persistent coastal fog intrusion that raises indoor humidity inside ductwork and promotes mold and mildew accumulation - a more pressing concern here than in inland Peninsula cities sheltered from the same airflow. Our HVAC duct cleaning runs $400-$750 for most residential systems, with commercial HVAC work quoted on-site.
We don’t just blow compressed air through the registers and call it done. Our HVAC service includes mechanical agitation of the entire duct run, cleaning of the evaporator coil and blower assembly, and inspection of the filter rack for bypass gaps. In San Bruno, where SFO jet-combustion particulates mix with wind-driven coastal grit, that thoroughness isn’t optional - it’s what keeps the system clean for more than a few weeks.
Supply and Return Duct Restoration
Supply ducts push conditioned air to your rooms; return ducts pull it back. Both sides need attention, but in San Bruno’s humid gap-wind environment, return ducts often show heavier microbial loading. We clean both with equal thoroughness, using Aprilaire and Abatement Technologies HEPA equipment to capture rather than redistribute contaminants.
Full System Integration
Your ducts don’t exist in isolation. We inspect and clean the air handler, coil, and filter housing as part of every HVAC duct cleaning. Skipping these components - common with cheap “blow-and-go” services - leaves the source of recontamination intact, which in San Bruno’s climate means the musty smell returns within a single fog season.
Trusted Brands We Service in San Bruno
Our trucks carry professional-grade equipment from Rotobrush, Nikro, Honeywell, Aprilaire, Abatement Technologies, and Guardsman - not the rental-grade gear you can pick up at a hardware store. For San Bruno customers, this means faster turnaround on jobs that require specialized tools, and no waiting for parts to ship from out of state. We’ve serviced homes with original Honeywell and Aprilaire media filters that have been running since the 1980s, and we know how to clean around legacy installations without damaging them. The equipment we use is chosen specifically for the Cedarwell Care Promise: thorough enough to make a real difference, gentle enough to protect 70-year-old sheet-metal ductwork.
Common Air Duct Cleaning Problems We See in San Bruno Homes
- Gap-wind grit accumulation in windward returns. Homes on western and windward-facing slopes toward San Bruno Mountain see exterior return-air grilles packed with fine grit and biological material that would take years to accumulate elsewhere. We clean these grilles as part of every full system service, not as an upsell.
- Joint separation in post-WWII sheet-metal ductwork. San Bruno’s residential neighborhoods are dominated by tract homes built between the late 1940s and late 1960s. Original ductwork in these homes is now 55-75 years old and prone to separation at the seams, allowing unfiltered gap air to bypass the filter and coat the air handler.
- Microbial growth from persistent fog intrusion. The San Bruno Gap’s moisture-laden airflow creates humidity levels inside ducts that inland Peninsula cities simply don’t experience. We find active mold and mildew in duct runs that have never been properly cleaned, especially in homes without whole-home dehumidification.
- False solutions from fogging “sanitisers.” A fogging upsell that mists the ducts without source removal leaves biofilm intact. In San Bruno’s humid micro-climate, that biofilm regrows within weeks. We don’t sell fogging as a standalone service because we’ve seen the callbacks.
Pricing for Air Duct Cleaning in San Bruno, CA
Here’s what honest pricing looks like for our market. A typical residential air duct cleaning in San Bruno runs $350-$650 for a complete system, depending on square footage, number of vents, and contamination level. HVAC duct cleaning with full air handler service runs $400-$750. Commercial properties and larger homes are quoted individually after a free on-site assessment.
What affects your specific cost? System size is the biggest factor - a 1,200-square-foot home with eight vents is simpler than a 3,000-square-foot home with twenty. Accessibility matters too; crawl space ductwork takes longer than basement or attic runs. And the condition of the ductwork itself - whether we’re cleaning intact modern flex duct or carefully restoring 1950s sheet-metal with joint separation - changes the time and technique required.
We give one flat price per system, agreed in writing before any work starts. No per-vent add-ons. No “we found a surprise” mid-job invoices. The price you approve is the price you pay. Call (323) 918-4345 for a free estimate - we’ll ask the right questions about your home and give you a real number you can plan around.

FAQs About Air Duct Cleaning in San Bruno
San Bruno sits directly in the San Bruno Gap, a wind corridor that funnels persistent Pacific moisture and SFO jet-combustion particulates into residential HVAC systems at higher velocity than neighboring cities. Millbrae and South San Francisco sit outside the gap’s direct wind shadow, and San Mateo’s inland location shelters it from the same coastal fog intrusion. That gap-driven loading means San Bruno ducts accumulate grit and microbial growth faster, and the elevated humidity promotes mold and mildew accumulation sooner than in those nearby cities. Call (323) 918-4345 for a free assessment of your system’s condition.
No - not for more than a few weeks. Fogging “sanitisers” mist the duct interior without removing the source contamination. In San Bruno’s humid gap-wind micro-climate, the biofilm that produces musty odors regrows rapidly on that remaining substrate. A genuine clean requires mechanical agitation and extraction to remove the material, not just mask it. We don’t sell fogging as a standalone service because we’ve handled too many callbacks from homeowners who paid for it elsewhere and watched the smell return. Call (323) 918-4345 and we’ll show you what source removal actually looks like.
Most can be cleaned, but they need inspection first. The Crestmoor neighborhood contains a patchwork of newer construction alongside surviving older homes, and our technicians may encounter brand-new duct systems on one block and severely aged originals on the next. Original sheet-metal ductwork that’s pulling apart at the joints or showing interior liner degradation can often be sealed and restored rather than replaced, at a fraction of the cost. Our video inspection shows you exactly what condition your ducts are in before you commit to any work. Call (323) 918-4345 to schedule.
A genuine cleaning includes video inspection, mechanical agitation of the full duct run, HEPA-filtered negative air extraction, cleaning of the air handler and coil, and inspection of exterior returns - especially critical in San Bruno, where windward-facing grilles clog faster than Peninsula norms. A “blow-and-go” typically blasts compressed air through the registers without agitation, skips the air handler entirely, and leaves the source of recontamination intact. The difference shows up in your energy bills, your indoor air quality, and how long the results last. We back our work with the 365-Day Done Right Promise. Call (323) 918-4345 for an estimate.
The San Bruno Gap channels cool, moisture-laden Pacific air through the city at high velocity, creating a micro-climate with persistent fog intrusion that raises humidity levels inside ductwork. That elevated humidity promotes mold and mildew accumulation on dust and debris that collects in the system - a more pressing concern here than in inland Peninsula cities sheltered from the same airflow. Without periodic source removal, that microbial growth circulates through your home every time the HVAC runs. Our Air Duct Cleaning team addresses this with thorough mechanical extraction, not surface treatments. Call (323) 918-4345 for a free estimate - we’ll assess your system’s humidity load and contamination level.
