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.

AfterAir Duct Cleaning in Millbrae, CA
Dryer vent cleaning in Millbrae is not a once-a-decade chore. The city sits directly beneath the SFO flight approach, and the same marine layer that keeps Millbrae cool also keeps duct interiors damp. Homes here, most built in the 1950s and 1960s west of El Camino Real, carry rigid sheet-metal ductwork with aging seals. That combination means lint, jet particulates, and moisture collect faster than homeowners expect. If your dryer has been taking longer than it used to, call (806) 606-6902 and we’ll start with a written price before any panel comes off.
Why Millbrae Homes Are Different
Millbrae sits immediately south of SFO’s runways, placing thousands of homes under primary flight approach corridors. The result is a constant deposit of aviation-grade particulates and kerosene combustion byproducts that inland Peninsula cities simply don’t experience. Our techs working the flatland neighborhoods near the Millbrae BART/Caltrain station routinely find a dark, oily residue on supply registers that homeowners mistake for neglect. It’s jet exhaust infiltration, and it accumulates fast.
The housing stock compounds the problem. Most flatland homes west of El Camino Real were built as post-war tract development in the 1950s and 1960s, which means 60-plus-year-old rigid sheet-metal ducts with deteriorating mastic seals and shedding fiberglass liner. Hillside ranch and split-level homes above Millbrae Avenue often have long, complex duct runs never designed for modern filtration. Add the Pacific marine layer rolling through the SFO corridor, and you get persistently elevated humidity inside ductwork. Mold and mildew colonize Millbrae duct surfaces faster than in drier Peninsula communities, which is why so many of our jobs here involve both cleaning and sanitizing.
Our Main Millbrae Services
Most Millbrae homeowners call us first for one of two jobs, and each has its own dedicated page with detailed pricing and local specifics.
Air Duct Cleaning in Millbrae
Full-system duct cleaning removes the layered debris that accumulates in Millbrae’s older homes, from jet particulate residue to fiberglass liner particles and decades of household dust. We photograph every duct run before and after, so you see exactly what was pulled out. In the flatlands near El Camino Real, we often find enough debris to fill a five-gallon bucket from a single system. Read the full breakdown on our Air Duct Cleaning in Millbrae page, including the written-price guarantee and photo documentation process.
HVAC Cleaning in Millbrae
HVAC cleaning goes beyond the ducts to cover the blower motor, evaporator coil, and plenum, which in Millbrae’s damp, jet-adjacent air collect oily film that reduces system efficiency. Many Millbrae homes have original furnace installations paired with newer AC condensers, and the mismatch leaves coils working harder. Our HVAC Cleaning in Millbrae page covers what we inspect, what we clean, and what it costs before work begins.

BeforeAfterDryer Vent Cleaning in Millbrae
Dryer vent cleaning in Millbrae is a safety issue first and an efficiency issue second. The city’s 60-year-old housing stock means many dryer vents are original rigid ducts, some running 20 feet or more from the laundry closet to the exterior wall. Lint packing into those long runs is the leading cause of dryer fires, and Millbrae’s damp marine air makes the lint denser and harder to remove. We clean the full run from dryer connection to exterior termination and photograph the before and after so there’s no question the job was done. This is part of our standard Dryer Vent Cleaning service line.
Dryer Vent Inspection
Signs you need it
Clothes take more than one cycle to dry, the dryer feels hot to the touch, or you notice a burning smell during operation.
What it costs in Millbrae
Inspection as part of a standard cleaning runs $89-$149; a standalone camera inspection starts at $129.
How we do it
We run a camera from the dryer connection to the exterior termination, measure the vent length, and photograph any blockages, gaps, or damage.
Vent Cleaning
Signs you need it
Lint deposits at the exterior vent opening, visible buildup inside the pipe, or the dryer’s “check vent” light stays on.
What it costs in Millbrae
Standard vent cleaning runs $149-$249 for a single-run vent, with longer or multi-story runs at $259-$349.
How we do it
We snake a rotating brush the full length of the vent under negative pressure, then show you the before-and-after photos of the entire run.
Lint Removal
Signs you need it
Dryer cycle times have crept up 20 minutes or more, or you find fine lint dust settling on surfaces near the laundry area.
What it costs in Millbrae
Deep lint extraction from clogged or long vents costs $199-$299, depending on vent length and obstruction density.
How we do it
We use a HEPA-filtered negative-pressure system to pull the loosened lint out without blowing dust back into your home.
Bird Guard Installation
Signs you need it
You hear scratching or chirping near the dryer vent, or you see nesting material poking out of the exterior termination.
What it costs in Millbrae
Bird guard installation runs $89-$149 including the guard and labor, done same visit as any cleaning.
How we do it
We cut a small aluminum screen to fit your vent termination, mount it with rust-resistant hardware, and verify airflow isn’t restricted.
What Dryer Vent Cleaning Costs in Millbrae
| Item | Typical range in Millbrae |
|---|---|
| Dryer vent inspection | $89-$149 |
| Standard single-run vent cleaning | $149-$249 |
| Deep lint extraction (clogged or long vents) | $199-$299 |
How often should dryer vents be cleaned in Millbrae?
Every 12 to 18 months for most Millbrae homes. If you dry laundry more than four times per week or your vent runs 15 feet or more, clean it annually. Call (806) 606-6902 to schedule.
Can a blocked dryer vent cause a fire?
Yes. Lint is flammable, and a blocked vent traps heat inside the dryer drum and exhaust path. Millbrae’s older, longer vent runs pack lint faster than short modern installs. Written inspection photo records catch it before it’s dangerous.
Duct Repair & Sealing in Millbrae
Millbrae’s post-war ducts are six decades old, and the mastic seals at every joint have dried and cracked. Add the constant humidity from the marine layer, and you get gaps that pull crawlspace air and jet particulates straight into the living space. We locate every leak with a pressure test and seal each point with mastic or butyl tape, then photograph the repair before and after. Our Duct Repair & Sealing service is quoted in writing before work starts.
Duct Sealing
Signs you need it
Rooms at the end of the house stay warmer or cooler than the rest, utility bills climb, or you see dust streaks around supply registers.
What it costs in Millbrae
Whole-system duct sealing runs $450-$950, depending on the number of joints and level of access in the crawlspace.
How we do it
We run mastic and butyl tape over every accessible joint after a blower-door or smoke test shows us exactly where air is escaping.
Metal Duct Repair
Signs you need it
You can see crushed, rusted, or separated sections of metal duct in the crawlspace, or you hear air whistling under the floor.
What it costs in Millbrae
Section replacement or patching runs $250-$600 per affected run, with full-run replacement at $800-$1,400.
How we do it
We cut out the damaged section, fit a matching galavanized steel collar, secure it with sheet-metal screws, and seal both joints with mastic.
Duct Insulation
Signs you need it
Condensation forms on duct surfaces in the crawlspace, or cooled air warms before it reaches the register in summer.
What it costs in Millbrae
Insulation wrap runs $300-$700 for a typical crawlspace system, depending on accessible duct length.
How we do it
We wrap exposed duct runs with R-6 or R-8 fiberglass duct insulation, seal the seams with foil tape, and photograph the finished run.
What Duct Repair & Sealing Costs in Millbrae
| Item | Typical range in Millbrae |
|---|---|
| Whole-system duct sealing | $450-$950 |
| Metal duct section repair or patching | $250-$600 per run |
| Duct insulation wrap | $300-$700 |
Why do Millbrae ducts leak more than newer homes?
Most Millbrae homes were built with rigid sheet-metal ducts sealed with mastic that dries and cracks over 60-plus years. The damp marine air accelerates the deterioration at every joint.
Can leaking ducts make my energy bill higher?
Yes. Leaks pull unconditioned crawlspace air into the system, forcing the furnace or AC to run longer. Written pricing covers the full scope before we start, so there’s no surprise.
Air Quality & Sanitizing in Millbrae
Millbrae’s position under the SFO approach means ultrafine particles settle inside every duct run. When you combine that with marine-layer humidity, you get microbial growth on duct surfaces that ordinary vacuum cleaning won’t remove. We sanitize with EPA-registered antimicrobial agents and install UV lights where the existing HVAC system can support them. Every job is part of our Air Quality & Sanitizing line, with a written price before work begins.
Mold Treatment
Signs you need it
Musty smell from supply registers, visible dark spots on duct interiors during inspection, or family members waking with congestion that clears when away from home.
What it costs in Millbrae
Antimicrobial fogging and surface treatment runs $299-$599 per system, depending on duct run count and infestation severity.
How we do it
We fog EPA-registered antimicrobial into the full duct network under negative pressure, then photograph the treated surfaces before and after.
UV Light Installation
Signs you need it
Recurring coil mold despite cleaning, or a family member with respiratory sensitivity to airborne spores and bacteria.
What it costs in Millbrae
UV light installation runs $599-$1,100 per unit, depending on lamp wattage and whether an additional electrical tap is needed.
How we do it
We mount a UV-C lamp inside the supply plenum aimed at the evaporator coil, wire it to the existing furnace control board, and verify it powers on with the blower.
Odor Removal
Signs you need it
Cooking, pet, or smoke odors recirculate through the house even after venting, indicating the smell has bonded to duct surfaces.
What it costs in Millbrae
Whole-system odor treatment runs $249-$499, often combined with a full duct cleaning for best results.
How we do it
We run a thermal fog through the system that neutralizes odor molecules on duct surfaces, then follow with HEPA-negative-pressure extraction.
What Air Quality & Sanitizing Costs in Millbrae
| Item | Typical range in Millbrae |
|---|---|
| Mold treatment / antimicrobial fogging | $299-$599 per system |
| UV light installation | $599-$1,100 per unit |
| Whole-system odor removal | $249-$499 |
Does Millbrae’s airport proximity really affect indoor air quality?
Yes. Jet exhaust ultrafine particles are pulled into HVAC intakes and settle in ducts. The dark oily residue found on Millbrae registers is a documented signature of long-term aviation particulate infiltration.
Will sanitizing get rid of the musty smell from my vents?
Usually yes. Musty odors come from microbial growth on duct surfaces, and antimicrobial fogging kills the source. Written pricing covers the full scope before any work starts.
