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 Burlingame
Air duct cleaning in Burlingame typically runs $450 – $850 for a whole-home system, and most jobs are scheduled within a few days of your call. We’re the local crew that shows up when we said we would, prices the job in writing before touching anything, and cleans by the book – not with a fogging upsell that masks the real problem.
Our dispatch team coordinates from the San Francisco Bay Area office, and our crews serve Burlingame directly. We know the difference between a pre-1940s bungalow in Easton Addition with galvanized steel ducts sweating in a damp crawlspace and a Bayfront townhome with kinked flex runs that never got properly agitated. That local knowledge changes what equipment we bring and how we set up the job. If you’re catching a musty smell every time the heat kicks on, or you’ve noticed your system’s working harder than it should, call (361) 326-5060. We’ll walk you through what you’re actually dealing with and give you a written price before we schedule anything.

We serve Air Duct Cleaning in Burlingame with the same professional-grade equipment commercial crews use: Rotobrush rotary brush systems, Nikro negative-air machines, and filtration from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. We explain what each tool does and why it matters for your specific duct type – because a galvanized trunk line in Burlingame Park needs a different approach than flex duct downtown.
Air Duct Cleaning Services in Burlingame
Air Duct Cleaning Services in Burlingame mean source removal – physically dislodging and extracting debris, dust, and biological growth from your supply and return runs, not spraying a deodorizer and calling it done. A typical residential whole-system clean in Burlingame runs $450 – $650 for a standard single-furnace home, while larger homes or systems with heavy buildup can reach $750 – $850. Commercial duct cleaning starts around $800 and scales with system size and access difficulty.
We use the negative-air method: a powerful vacuum at the air handler creates suction through the entire duct network while rotary brushes or compressed-air whips agitate debris loose from the walls. HEPA filtration captures what we pull out so it doesn’t resettle in your home. For Burlingame’s older homes with original galvanized ducts, we add moisture assessment – because if your crawlspace trunk line is condensing, cleaning without addressing the damp environment is temporary at best.
Residential Duct Cleaning
Most Burlingame homes we see are single-family residences with one furnace and 12 – 20 supply and return registers. Our residential clean covers all accessible ductwork, the return plenum, and the supply trunk, with before-and-after photos so you see what came out. We don’t price per vent – one flat price per system, agreed before we start.

Commercial Duct Cleaning
Burlingame’s commercial buildings – medical offices along El Camino Real, retail near Broadway, professional suites downtown – need scheduled cleaning that doesn’t disrupt operations. We work after hours and weekends, set containment barriers, and provide documentation for facility managers and compliance records.

HVAC Duct Cleaning in Burlingame
HVAC Duct Cleaning in Burlingame requires understanding how our coastal climate hits different housing stock. The same marine layer that keeps summers mild also keeps crawlspaces damp, and that moisture converts settled dust into active mold colonies inside ductwork – especially in unconditioned spaces. A typical HVAC duct cleaning in Burlingame runs $500 – $750 for residential systems, with commercial HVAC cleaning starting at $900.
We inspect first. Camera inspection lets us show you what’s actually inside your ducts – corroded galvanized steel with biological growth, kinked flex duct loaded with construction debris, or a clean system that doesn’t need service yet. If we don’t find a problem worth fixing, we’ll tell you. The inspection itself is part of our estimate process, and estimates are free.
Supply and Return Cleaning
Supply ducts push conditioned air into your rooms; returns pull it back to the air handler. Both sides need cleaning, but returns typically load up faster because they’re the intake – pulling in dust, pet hair, and whatever’s airborne in your living space. In Burlingame homes near the Bayfront, we’ve found return ducts packed with salt-air corrosion residue that standard filters don’t catch.
Full System Cleaning with Video Inspection
Our full system clean includes every accessible component: supply trunk, return plenum, branch lines, boots, and the air handler cabinet. We record video before and after so you see the change in your own ducts, not a stock photo from someone else’s job. That documentation matters if you’re addressing indoor air quality concerns or preparing a home for sale.
Trusted Brands We Service in Burlingame
We stock filtration and cleaning equipment from Aprilaire, Abatement Technologies, and Guardsman – brands that hold up in commercial environments and translate directly to better results in your home. Our Rotobrush rotary systems and Nikro negative-air machines are the same units you’ll see on hospital and school jobs, not hardware-store vacuums with a longer hose. For Burlingame customers, that means parts and filters are available without multi-week special orders, and our technicians know the equipment well enough to troubleshoot on-site rather than guessing. If your system uses Honeywell or Aprilaire media filters, we carry replacements and can show you the MERV rating that actually matches your furnace’s airflow capacity – a common mismatch we see in newer Bayfront construction where builders spec’d high-MERV filters on undersized blowers.
Common Air Duct Cleaning Problems We See in Burlingame Homes
- Musty odors from Easton Addition crawlspaces. Original galvanized ducts running through unheated, unvented crawlspaces draw in cool, moist bay air and condense on the metal surface. That moisture feeds mildew that blows into living spaces every time the fan cycles. Fogging the registers doesn’t reach the colony on the trunk line.
- Kinked flex duct in Bayfront townhomes. Modern flexible ducting is prone to sharp bends and compression during installation, creating debris traps that standard vacuuming won’t clear. Without rotary agitation and camera verification, those kinks stay loaded.
- Asbestos-wrapped ducts in pre-1940s bungalows. Burlingame Park and Easton Addition homes often have original duct insulation containing asbestos. We identify this during inspection and follow Cal/OSHA handling protocols – disturbing it without proper containment is illegal and dangerous.
- Salt-air corrosion near the Bayfront. Homes within a few blocks of the water see accelerated corrosion on metal duct components and faster filter loading. The marine layer carries fine salt particles that standard fiberglass filters don’t capture effectively.
Pricing for Air Duct Cleaning in Burlingame, CA
A typical residential air duct cleaning in Burlingame runs $450 – $650 for a standard single-system home. Larger homes, multi-zone systems, or properties with heavy biological growth requiring extended HEPA-contained cleaning can reach $750 – $850. Commercial duct cleaning starts at $800 and scales with square footage, access difficulty, and whether the work must happen outside business hours.
What moves the price: the number of air handlers, how many registers and returns, whether we need to set up containment for asbestos-wrapped ducts, and the actual condition we find inside. We don’t bait with a low per-vent teaser and triple the invoice at the door. One flat price per system, written down, agreed before work starts. If we find something unexpected during inspection – a disconnected duct, a dead rodent, significant mold – we stop, show you, and give you a revised written price before continuing. No surprises. Estimates are free. Call (361) 326-5060 to schedule.

FAQs About Air Duct Cleaning in Burlingame
Burlingame’s Easton Addition and Burlingame Park bungalows run original galvanized ducts through unheated crawlspaces that sit in cool, moist bay air year-round. That metal condenses moisture in a way drier inland climates don’t, and that damp surface grows mildew that inland ducts rarely see. A real source-removal clean with negative pressure and agitation fixes it; fogging the registers does not. Call (361) 326-5060 for an inspection and exact quote – estimates are free.
No. A fogging sanitiser masks odor with a chemical fragrance but does not remove the physical mold colony or the moisture feeding it. In Burlingame’s condensing crawlspace ducts, the colony sits on the trunk line surface – fog never reaches it in sufficient concentration, and even if it did, dead mold spores are still allergenic. We do true source removal: agitation, extraction, and HEPA containment. If you want antimicrobial treatment after cleaning, we offer it as a separate, optional service with full disclosure of what it does and doesn’t do. Call (361) 326-5060 to discuss what your system actually needs.
Yes, but often for different reasons. Newer flex duct in Bayfront townhomes doesn’t corrode like galvanized steel, but it kinks, compresses, and traps construction debris that the builder’s rough clean missed. We’ve found brand-new flex runs loaded with drywall dust, wood scraps, and filter bypass debris. Camera inspection tells you whether your specific system needs service or can wait. Call (361) 326-5060 for a free look.
Winter rain saturates crawlspace soil, raising humidity for weeks after the storm passes. Summer fog rolls in overnight and keeps morning humidity above 80% through July and August. That sustained moisture, combined with cool duct surfaces, creates ideal conditions for biological growth inside ductwork – especially in unconditioned spaces. Homes with proper vapor barriers and sealed crawlspaces fare better, but many Burlingame bungalows lack both. We assess moisture conditions during inspection and can recommend ventilation improvements alongside cleaning. Call (361) 326-5060 to schedule.
Yes, when handled by technicians following proper protocols. We identify asbestos-wrapped ducts during camera inspection and set up full containment before disturbing anything. The work area is isolated, air is filtered through negative pressure, and waste is bagged and disposed of per Cal/OSHA requirements. Cleaning asbestos-wrapped ducts costs more due to containment setup, but it’s legal, safe, and commonly done in Burlingame’s historic housing stock. We do not clean asbestos-containing material without containment – anyone who says otherwise is cutting corners on your safety. Call (361) 326-5060 for a specific assessment of your system.
