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 San Carlos, CA
Dryer vent cleaning in San Carlos runs $149 to $289 for a standard single-story home, and most jobs take 60 to 90 minutes. The work matters more here than in drier Peninsula cities because the marine layer pushes sustained attic humidity through the flatland neighborhoods of White Oaks and Howard Park, and that moisture turns lint into a heavier, stickier accumulation inside vent runs. If you’re in a 1950s or 1960s ranch home here, call (806) 606-6902 and we’ll give you a written price before any work starts.
Why San Carlos Homes Are Different
San Carlos’s flat bay-side sections are dominated by 1950s and 1960s California ranch homes with original sheet-metal duct systems now 60 to 70 years old. In White Oaks and Howard Park, and along the blocks flanking El Camino Real, most of that original ductwork routes through unconditioned attic spaces with poor sealing. The marine layer that pushes inland most mornings and evenings creates humidity swings in those attics that are not typical of drier inland cities nearby. Those repeated wet-dry cycles crack flex-duct liners and gap sheet-metal joints, drawing attic insulation fibers and mold spores into the living-space airstream.
There’s a local retrofit pattern we see repeatedly. Original 1950s trunk lines were extended with mismatched flex duct during 1980s and 1990s HVAC upgrades. The joints were often left unclamped and are now buried in blown insulation. That means a standard cleaning in San Carlos is far more involved than a single-era system: the debris settles at those buried transition points, and the airflow path itself is compromised. Hillside homes above Crestview Drive, built mostly in the 1960s and 1970s, have slightly newer ductwork but the same attic-routing problem and the same exposure to bay-driven humidity.
Our Main San Carlos Services
Most San Carlos homeowners call us first about two things: the full air duct cleaning of the entire forced-air system, and HVAC cleaning of the furnace, coil, and blower assembly. Both jobs start with the same written-price promise and end with the same documented photo record.
Air Duct Cleaning in San Carlos
Air duct cleaning in San Carlos is a whole-system job. We open every register, run negative-pressure extraction through the supply and return sides, and photograph the interior of each duct run before and after. In a 1950s ranch here, the job almost always includes clearing out insulation fibers and rust flakes from the original sheet-metal plenum and trunk line, then documenting the transition points where flex duct was retrofitted decades ago. You’ll see the inside of your ducts before you pay for anything. Read more on our Air Duct Cleaning in San Carlos page.
HVAC Cleaning in San Carlos
HVAC cleaning in San Carlos focuses on the equipment upstream of the ducts: the blower wheel, evaporator coil, drain pan, and the return plenum. The attic humidity that defines this stretch of the mid-Peninsula coats these components with a damp, sticky film that captures dust and supports microbial growth. We document that buildup with photos, clean to manufacturer spec using professional-grade equipment, and deliver the photo record with your invoice. Full equipment details are on our HVAC Cleaning in San Carlos page.

BeforeAfterDryer Vent Cleaning in San Carlos
Dryer vent cleaning in San Carlos costs $149 to $289 for a typical single-story home, and the job is done in about an hour to an hour and a half. The flatland ranch homes of White Oaks and Howard Park usually have short, straight vent runs that exit through the roof or a side wall; those runs collect lint faster in San Carlos because marine-layer humidity makes the lint heavier and stickier inside the pipe. After cleaning, you’ll receive a photo record of the full run: the before and after. You can read more about the service on our Dryer Vent Cleaning page.
Dryer Vent Inspection
Signs you need it
Clothes take longer than 40 to 45 minutes to dry, the dryer exterior gets hot to the touch, or you can smell a musty damp odor when the dryer runs.
What it costs in San Carlos
A standalone inspection with camera documentation runs $89 to $149, and the fee is credited toward the cleaning if you proceed.
How we do it
We disconnect the vent at both ends, run a camera through the full length to document the blockage and the condition of the pipe, then show you the photos before we quote any repair or cleaning work.
Lint Removal
Signs you need it
Visible lint is building up around the dryer’s exterior vent flap, or the dryer shuts off mid-cycle on its high-limit safety switch.
What it costs in San Carlos
Full lint removal is part of the standard vent cleaning at $149 to $289, depending on run length and accessibility.
How we do it
We run a rotary brush and negative-pressure vacuum through the full vent run, then photograph the complete interior to document that the lint is gone from the dryer connection to the exterior termination.
What Dryer Vent Cleaning Costs in San Carlos
| Item | Typical range in San Carlos |
|---|---|
| Dryer vent inspection with camera | $89 - $149 |
| Standard dryer vent cleaning (single story) | $149 - $229 |
| Extended or multi-story vent run | $229 - $289 |
How often should a dryer vent be cleaned in San Carlos?
Every 12 months for homes in White Oaks, Howard Park, and the flats near El Camino Real, where the marine layer keeps lint denser and stickier. Homes with longer roof-terminated runs above Crestview should stay on the same annual schedule.
Why does my dryer vent clog faster in San Carlos than in Redwood City?
The bay-driven humidity that sits over San Carlos most mornings makes lint heavier and stickier, so it clings to the vent walls instead of blowing through. Call (806) 606-6902 for an exact written quote.
Duct Repair & Sealing in San Carlos
Duct repair and sealing in San Carlos addresses the single most common failure in this city’s housing stock: 60-year-old sheet-metal joints that have gapped open from repeated humidity cycles in the attic, and flex-duct liners that cracked under the same conditions. In White Oaks and Howard Park, we routinely find that the 1980s and 1990s retrofit flex connections were never clamped to begin with, and they now sit buried in blown insulation, slowly leaking conditioned air into the attic. The fix starts with a camera inspection of every accessible run, then a written scope of what actually needs sealing or replacing. You can read more about the service on our Duct Repair & Sealing page.
Duct Sealing
Signs you need it
Rooms at the far end of the house stay hot or cold despite the thermostat reading normal, or your energy use climbs during peak heating and cooling months.
What it costs in San Carlos
Sealing exposed accessible duct joints with mastic runs $350 to $700 for a typical single-story San Carlos ranch.
How we do it
We locate every accessible joint by hand and camera, clean the mating surfaces, apply mastic sealant to each seam, and photograph every joint after the sealant cures.
Flex Duct Repair
Signs you need it
You can see a collapsed or kinked section of flex duct in the attic, or a register blows weakly while others blow strongly.
What it costs in San Carlos
Replacing a damaged flex duct run costs $225 to $500, depending on the run length and how much of it is buried in blown insulation.
How we do it
We remove the damaged flex section, install the new run with proper clamps and support straps, seal both connection points, and photograph the finished work end to end.
What Duct Repair & Sealing Costs in San Carlos
| Item | Typical range in San Carlos |
|---|---|
| Duct inspection with camera documentation | $149 - $249 |
| Sealing exposed accessible joints | $350 - $700 |
| Flex duct run replacement | $225 - $500 |
Why do ducts in San Carlos ranchers leak more than in newer homes?
Original 1950s sheet-metal ducts were never engineered for the humidity swings the marine layer causes in unconditioned attics. Those repeated wet-dry cycles work joints apart over time. Call (806) 606-6902 to get a written scope of your system.
Can you seal ducts that are buried in blown insulation?
Yes, but the job requires carefully moving the insulation to expose each joint, then replacing it after sealing. That added labor is reflected in the written price you’ll receive before we start.
Air Quality & Sanitizing in San Carlos
Air quality and sanitizing in San Carlos usually means treating the biological fallout of an attic-routed duct system that’s spent decades in marine-layer humidity. The mold colonies and bacteria that form in gapped sheet-metal joints and cracked flex duct liners release spores and odors into the airstream, and a standard duct cleaning alone doesn’t kill what’s living on the surfaces. We treat the full system after documenting exactly where the contamination sits. You can read more about the service on our Air Quality & Sanitizing page.
Mold Treatment
Signs you need it
Musty odor comes from the registers when the system runs, or you’ve spotted visible mold growth around the supply vents or inside the ductwork during an inspection.
What it costs in San Carlos
Full system mold treatment ranges from $450 to $900, depending on the length of the duct runs and the extent of the contamination.
How we do it
We apply an EPA-registered antimicrobial to all accessible duct surfaces with professional equipment, allow the correct dwell time, then photograph the treated surfaces as part of the permanent record.
Odor Removal
Signs you need it
Persistent smells of dampness, pet dander, or old smoke linger in the house even after replacing filters and cleaning surfaces.
What it costs in San Carlos
Duct-level odor treatment runs $300 to $550 for a standard single-story home and is often combined with a full sanitizing pass.
How we do it
We identify the source of the odor with a camera inspection, clean the affected surfaces, then apply a deodorizing treatment through the duct system to neutralize the smell at its source.
What Air Quality & Sanitizing Costs in San Carlos
| Item | Typical range in San Carlos |
|---|---|
| Full system mold treatment | $450 - $900 |
| Duct-level odor removal | $300 - $550 |
| UV light installation (coil and plenum) | $600 - $1,200 |
Does sanitizing the ducts do anything if the ducts still leak?
No, and we’ll tell you that before you spend the money. If the camera shows gapped joints or cracked flex duct, we recommend sealing or repair first, then sanitizing. Call (806) 606-6902 for a written scope.
Is the sanitizing product safe for a house with kids and pets?
We use EPA-registered products applied at the labeled concentration, with clear re-entry guidance provided in writing. The product label and safety data sheet are available to any customer who asks.

| Duct-level odor removal | $300 - $550 |
| UV light installation (coil and plenum) | $600 - $1,200 |
Two things push San Carlos pricing toward the upper end of these ranges: buried transition points from 1980s and 1990s retrofits that require moving insulation to inspect and seal, and the extra labor of working in the low-clearance attic spaces common to 1950s ranch homes. Whatever the exact number, you’ll have it in writing before any panel comes off, and that price is the price.

"Flat price agreed up front, no per-vent add-ons at the end. That was the whole reason I did not call the coupon company."
- Suzanne B."The dryer vent was almost completely blocked with lint. They showed me the photograph and I understood immediately why the dryer had been running twice."
- Lucia M."They found a disconnected duct in the crawl space that had been dumping conditioned air under the house for years. Photographed it, quoted the repair, fixed it."
