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
Air duct cleaning in Redwood City takes on a different character than in the flatter, newer parts of the Bay Area. Our crews work in a mix of 1950s ranchers near downtown, 1970s hillside homes off Farm Hill Boulevard, and newer builds in Redwood Shores. Each stock fights its own battle with duct debris: the older homes with decades of layered dust, the hillside properties with wildfire-season ash pull-in, and the Shores homes with salt-air humidity from the bay. We’re Cardinal Air Duct Cleaning, part of the Relay Home Co. family, and if you’d rather talk it through before reading on, call (737) 727-2314 and a live person picks up.
Why Redwood City Homes Are Different
Redwood City’s climate is a split personality. “Climate Best by Government Test” isn’t just a slogan on the arch downtown; it means warm, dry summers that bake fine dust into return ducts, and damp, fog-touched winters that can turn that dust into a paste against duct walls. Homes built before 1990 around Roosevelt, Stambaugh-Heller, and Palm Park often have original galvanized duct runs with mastic-sealed joints that have cracked. That lets unconditioned attic air pull into the return side, and with it, fine redwood duff and roof-grit from the hills. Meanwhile, Redwood Shores and the lagoon-side neighborhoods deal with a different problem: bay fog and humidity that encourages organic matter to bind to accumulated dust, which is often what homeowners smell when the furnace kicks on in October. Add in the fact that many Redwood City homes sit on the Peninsula’s marine terrace or up against the Santa Cruz range foothills, and you get steep roof pitches, long attic runs, and mechanical rooms that are tighter than anything a louvered closet in a flat Central Valley home would present.
We also see a lot of fire-season carryover. When ash drift from regional wildfires settles on Redwood City roofs and streets, the tiny particulates find their way into open windows, door sweeps, and ultimately the return grilles. That means a duct system that was reasonably clean in May can be carrying a surprising amount of fine ash by September. It’s one reason we rarely tell a Redwood City homeowner a duct cleaning was “light”; the city’s dry-season air is stiffer than people assume.
Our Main Redwood City Services
Three jobs make up most of our work in Redwood City, and each one has its own dedicated page with pricing, timelines, and what to expect in the home. Here’s what you’re looking at.
Dryer Vent Cleaning in Redwood City
Dryer vents in Redwood City run longer than homeowners expect, especially in two-story ranchers where the laundry room sits on the ground floor and the vent exits through the roof. That long run means more vent surface for lint to cake onto, and more total restriction before the dryer’s high-limit switch starts tripping. We clean the full run from the dryer transition to the exterior cap, and in Redwood City we pay extra attention to bird-guard and louver-style caps, which trap humid bay breeze and lint together. Our Dryer Vent Cleaning in Redwood City page covers the whole process and local pricing.
Air Duct Cleaning in Redwood City
This is the full-system job for Redwood City homes: supply ducts, return ducts, the plenum, and the blower cabinet. We use a Rotobrush rotary brush system for mechanical agitation paired with a Nikro HEPA-filtered negative-air vacuum. Negative-pressure extraction means the loosened debris goes straight into the vacuum, not back into your living room. Homes around Edgewood Park and the Emerald Hills side of town tend to need more attention at the return grilles, where the dry-summer dust loads are highest. Full breakdown on our Air Duct Cleaning in Redwood City page.
HVAC Cleaning in Redwood City
HVAC cleaning goes a step further than duct work: we pull the blower wheel, clean the evaporator coil if accessible, inspect the condensate pan and drain line, and wipe down the cabinet interior. In Redwood City, where a large share of furnaces live in tight side closets or under-home crawlspaces, that detail work matters. A dirty blower wheel quietly robs airflow all year, not just in summer. Read more at our HVAC Cleaning in Redwood City page, including what we find in the city’s older furnace models.

Pricing for Air Duct Cleaning Company in Redwood City, CA
Duct cleaning prices in Redwood City usually fall somewhere between $390 and $900 for a standard single-furnace home, depending on the size of the system and how heavily loaded the ducts are. The table below shows the typical sub-job ranges we see across the city.
| Service | Typical range in Redwood City |
|---|---|
| Standard air duct cleaning (single furnace, up to ~10 vents) | $390 – $650 |
| Larger system air duct cleaning (2 furnaces or 14+ vents) | $600 – $900 |
| Dryer vent cleaning (standard residential run) | $140 – $230 |
| Dryer vent cleaning with roof or high-angle exit | $180 – $290 |
| HVAC cleaning – blower wheel and cabinet only | $180 – $320 |
| HVAC cleaning – full: blower, coil, pan, drain line | $330 – $550 |
| Supply duct register sanitizing (per system) | $120 – $190 |
| Filter replacement with basic 1-inch media | $40 – $90 |
Redwood City prices can climb above these ranges when a home has roof-only access to the air handler, a finished attic that squeezes duct runs into eaves, or a high-ceiling landing that makes the return chase hard to reach. That said, you’ll never see a number change once we hand it to you: a written price is given before any work starts, and it holds. No upsell surprise at the door.
