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 Company in Redwood City, CA
Redwood City homes pull more dust, salt, and moisture into their ductwork than most of the Peninsula. The inland ranch neighborhoods like Farm Hill and Emerald Hills are full of 1950s and 60s homes still running their original sheet-metal trunks, now packed with decades of compacted debris. Redwood Shores, built on former baylands, has the opposite problem: salt-laden marine air and high humidity that can leave moisture staining inside ducts in homes under ten years old. We’re Kestrel Air Duct Cleaning, and if you want a straight answer about what’s in your ducts and what it costs to clean them, call (469) 972-3151.
Why Redwood City Homes Are Different
Redwood City sits at a geographic seam. The inland side, covering neighborhoods like Farm Hill, Edgewood, and Emerald Hills, shares the warm, dry microclimate the city has long been known for: “Climate Best by Government Test.” That means air conditioning runs noticeably more here than in fog-bound towns to the north, and conditioned air cycles more through the ducts. Dust drawn from attics and crawl spaces accumulates faster. Homes on this side of town, mostly built between the 1950s and 1970s, often still have original fiberglass-lined or bare metal ductwork. Fiberglass lining breaks down over fifty years and sheds particles. Metal trunks rust and separate at the seams, pulling insulation and attic dust into the airflow.
Then you have Redwood Shores. Developed from the late 1980s on reclaimed San Francisco Bay baylands, this neighborhood gives technicians a completely different set of findings. Bay air moves in from the water and carries salt. That salt corrodes uncoated metal duct components. The elevated relative humidity also means moisture condenses on cooler duct surfaces, which is exactly where mold and bacteria get their start. We routinely pull registers in Redwood Shores homes and find moisture staining or early-stage microbial growth in systems that aren’t even a decade old. Three miles away, near Jefferson Avenue or Woodside Road, the same technician finds dry, packed dust in a 60-year-old galvanized trunk. There’s no single Redwood City duct profile, and any company that treats it that way is guessing.
Our Main Redwood City Services
Two jobs dominate the calls we get from Redwood City homeowners: air duct cleaning and dryer vent cleaning. Each has its own dedicated page with pricing and the full scope of the work.
Air Duct Cleaning in Redwood City
Air duct cleaning in Redwood City means removing the accumulated dust, debris, and in some homes, moisture-driven biological growth from supply and return ductwork. On inland ranch homes, the work often focuses on decades of compacted particulate inside original metal trunks. In Redwood Shores, we check more carefully for early-stage mold and corrosion from bay air infiltration. The full explanation of how we clean, what the job includes, and what Redwood City pricing looks like sits on the service page: Air Duct Cleaning in Redwood City.
Dryer Vent Cleaning in Redwood City
Clogged dryer vents are common across Redwood City, but the cause varies by neighborhood. Inland homes deal with decades of lint layered inside long, often poorly routed vent runs. Redwood Shores homes face the added complication of bay humidity turning that lint dense and sticky, which accelerates clogs. When the vent packs with lint, the dryer overworks, clothes take longer to dry, and the odds of a lint fire climb. We run brush agitation and negative-pressure extraction through the full vent length and check the exterior termination. Details and scope for Redwood City are here: Dryer Vent Cleaning in Redwood City.

Pricing for Air Duct Cleaning Company in Redwood City, CA
Most Redwood City homes fall into predictable ranges based on home size, number of systems, and how long it’s been since the last cleaning. Here’s what the job typically runs here:
| Service | Typical range in Redwood City |
|---|---|
| Air duct cleaning, single system (up to 10 vents) | $349 - $599 |
| Air duct cleaning, larger home (11-20 vents) | $600 - $900 |
| Air duct cleaning, large or dual-system home | $1,000 - $1,800 |
| Dryer vent cleaning, standard run | $129 - $229 |
What pushes a Redwood City job toward the top of the range? Access. Crawl-space duct runs in older ranch homes often mean more time on the job than a newer Redwood Shores build with accessible attic trunks. Severely corroded registers or broken flex runs in Redwood Shores may also require replacement before cleaning can be effective. Whatever the number winds up being, it’s written down and in your hands before we touch a single vent.

In nearly all cases, no. Duct and dryer vent cleaning happens entirely inside the home and is considered routine maintenance, not a modification. If you’re in a Redwood Shores HOA with strict exterior rules, the only relevant piece is the exterior dryer vent termination, which we leave as-is. (469) 972-3151 if you have a specific HOA concern.

What Redwood City Customers Say
"Set up an appointment for the whole house plus the dryer line. They called the morning of to confirm, showed up in the window, and showed me pictures of the gunk they pulled out. Worth it."
- Terrence Boyd"My wife's allergies were awful every morning. Had the ducts done and it's made a real difference. Tech was on time and wore booties in the house without me asking."
- Rob Pendergast"Bought an older home and the previous owners had pets everywhere. After Kestrel did the ducts the stale smell was just gone. On time, quick, and they showed me the filter they pulled."
