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.

AfterFast, Reliable Air Duct Cleaning Across Redwood City
Air duct cleaning in Redwood City typically runs $450-$850 for a full residential system, with most homes falling in the $550-$700 range depending on duct age, accessibility, and whether video inspection reveals hidden moisture damage. We’re Morton’s Air Duct Cleaning, and our crews work Redwood City neighborhoods from Friendly Acres to Redwood Shores weekly, not as an afterthought from some distant dispatch center. Our Air Duct Cleaning team coordinates scheduling through our San Francisco Bay Area office, then arrives with Rotobrush and Nikro equipment loaded for the specific housing stock we know here: 1960s ranch sheet metal, 1980s townhome flex runs, and everything the bayfront humidity has done to both. Call (323) 918-4345 for a free written estimate before any work starts.
Why Morton’s Air Duct Cleaning Is Redwood City’s Preferred Air Duct Cleaning Company
We’ve been part of the Cedarwell family since 2005, and Redwood City has been in our rotation from the beginning. Homeowners here know us because we show up when we say we will, we wear shoe covers without being asked, and we hand over a written price before touching a single register. Our technicians are background-checked, uniformed, and trained to the Cedarwell C.A.R.E. values, which means quiet tool operation during nap hours and pet-safe product choices where available.
Every job ends with two things: a photo of the clean-up, so you see your home left better than we found it, and the 365-Day Done Right Promise stamped on your invoice. If something isn’t right, we make it right. No expiration date, no runaround. A live person answers our phone 24/7, not a voicemail tree.
What separates us in Redwood City specifically is that we understand the dual contamination problem here. Redwood City carries the verified designation “Climate Best by Government Test,” making it measurably warmer and sunnier than neighboring Peninsula cities. That means your A/C actually runs, loading ducts with debris at a rate unusual for the Bay Area coast. Simultaneously, bayfront neighborhoods like Redwood Shores sit in a persistent humidity zone where morning marine layer condenses inside ductwork. Heavy particulate plus moisture-driven mold risk. Foggier San Carlos to the north doesn’t see the same A/C load. Drier Menlo Park to the south doesn’t see the same humidity. Only Redwood City gets both.
Air Duct Inspection in Redwood City
Air Duct Inspection in Redwood City is where every job should start, especially in homes built between the 1950s and 1980s where original ductwork is now 50-70 years old. We run a camera through your supply and return lines, looking for standing water at low points, rust flaking on uninsulated sheet metal, collapsed joints, and compression damage in flex runs. A typical inspection in Redwood City runs $150-$250, and we apply that fee toward your cleaning if you proceed.
Post-Water-Intrusion Documentation
After a burst supply line or storm flooding, we document every foot of duct with timestamped video and moisture readings. This isn’t just for your peace of mind. Insurers need a written, line-by-line call on what can be cleaned versus what must be replaced. We provide that. Our field team has handled claims where saturated flex branches in Redwood Shores townhomes were approved for replacement while the dry trunk lines were cleared for HEPA cleaning.
Pre-Cleaning System Mapping
We map your full system before agitation begins, noting register locations, duct material transitions, and any previous repairs. In Friendly Acres ranches off the Jefferson corridor, we regularly find original sheet-metal trunks with undocumented 1990s flex additions. Knowing where those transitions are prevents us from damaging fragile connections during cleaning.
Residential Air Duct Cleaning in Redwood City
Residential Air Duct Cleaning in Redwood City covers the full forced-air system: supply ducts, return ducts, trunk lines, branch runs, and the registers themselves. We use Rotobrush agitation tools under negative pressure from Nikro collection systems, not shop vacs with brush attachments. A typical Redwood City home runs $550-$700 for complete cleaning, with larger systems or heavy contamination reaching $850. Every price is written and agreed before we start.
Protecting Your Home During Service
We lay drop cloths from the entry to your HVAC zone, cover furniture near registers, and note pet areas and nap schedules on our work order. Our crews work to the Cedarwell Care Promise: shoe covers on every visit, quiet tools during rest hours, and a photo of the clean-up before we leave. You’ll see exactly what we removed and exactly how we left your space.
Whole-System Approach
We don’t clean supply lines and ignore returns. Both sides get full attention, because contaminated return air just re-deposits debris into clean supplies. In Redwood City’s older ranch homes, we often find return plenums packed with decades of accumulation that never reached the filter. We clean those too.
Trusted Brands We Service in Redwood City
Our vans carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, not rental-shop gear that loses suction halfway through a job. For filtration and containment, we use Honeywell and Aprilaire components where the system calls for them. We stock common duct repair materials locally, so when inspection reveals a separable joint or compromised flex run in a Redwood Shores townhome, we can often address it same visit rather than scheduling a return trip. That matters when you’re already dealing with water damage or insurance timelines.
Common Air Duct Cleaning Problems We See in Redwood City Homes
- Standing water in sagged flex runs. In Redwood Shores and other bayfront areas, condensation pools at low points where flex duct has lost support. Cleaning a wet duct without addressing the moisture source just spreads mold spores through the system.
- Rust and joint failure in original sheet metal. Friendly Acres and Stambaugh corridor ranches from the 1950s-1970s often have uninsulated trunk lines with flaking corrosion and collapsed slip joints that camera inspection reveals but a register peek cannot.
- Unsupported flex runs in townhome ceilings. Redwood Shores condos built in the 1970s-1980s have aging flex that compresses, sags, and traps moisture from the area’s high ambient humidity, creating repeat mold cycles even after previous cleanings.
- Debris loading from actual A/C use. Redwood City’s warmer summers mean forced-air cooling runs hard enough to move significant dust and dander, unlike most Bay Area cities where natural ventilation handles summer comfort. Ducts here get dirty faster than homeowners expect.
Pricing for Air Duct Cleaning in Redwood City, CA

What moves you up or down within these ranges: duct material and age (sheet metal vs. flex, original vs. replaced), system accessibility (crawl space vs. attic), contamination level, and whether post-water-intrusion documentation is required for insurance. We do not quote per-vent pricing, because that incentivizes crews to rush registers and skip trunk lines. One flat price per system, agreed in writing, before any work starts.

FAQs About Air Duct Cleaning in Redwood City
Sometimes, but not always. Dry trunk lines and structurally sound metal can usually be HEPA-cleaned under negative pressure. Saturated flex branches, standing water at low points, or visible mold growth on porous materials must be removed and replaced. We document the distinction with camera video and moisture readings so your insurer understands the call. Call (323) 918-4345 and we’ll inspect before you commit to either path.
Redwood Shores sits on reclaimed tidelands at bay level, with a high water table and persistent marine-layer humidity that condenses inside cooling ducts. Flex runs sag and pool moisture at low points. Farm Hill and Edgewood homes sit higher and drier, with better natural drainage and less condensation pressure. We find standing water in Redwood Shores ducts on roughly one in three inspections. Up in the hills, it’s rare.
Only if the cleaning is documented properly and applied to the right components. Insurers pay for cleaning when ducts are contaminated but structurally intact. They deny claims where wet, porous materials were cleaned instead of replaced. We provide written, line-by-line documentation with timestamped video, giving your adjuster the technical basis to approve both the cleaning and replacement portions. We were called to a Friendly Acres ranch home off the Jefferson corridor where the original 1960s sheet-metal supply and return ducts had never been touched, and the homeowner had just filed a water-intrusion claim after a burst supply line soaked the subfloor. Using camera inspection and agitation tools under negative pressure, we found the trunk line dry and structurally sound but the branch runs holding standing water at a low point. We documented the wet sections, ran HEPA filtration on the dry runs, and gave the insurer a written line-by-line call on what could be cleaned versus what had to come out. The insurer approved replacement of the saturated flex branches and paid to clean the rest.
Most Redwood City homes benefit from cleaning every 3-5 years, sooner if you have pets, recent renovations, or visible dust accumulation at registers. The combination of actual A/C use plus bayfront humidity means ducts here load faster than in cooler, drier Peninsula cities. If you’re in Redwood Shores or another low-lying area, consider inspection every 2-3 years due to the moisture factor. Call (323) 918-4345 and we’ll assess your specific system.
We offer it as an add-on for $75-$125 when bundled with duct cleaning, or $150-$225 as a standalone service. Dryer vent cleaning is separate from duct cleaning because it involves a different run, different termination point, and different fire-safety considerations. We use Nikro rotary tools and check exterior termination clearance. In Redwood City’s older homes, we frequently find vinyl or foil transition ducts that should be replaced with solid metal per current safety standards.
