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.

AfterHow Much Does Air Duct Cleaning Cost in Redwood City?
Air duct cleaning in Redwood City typically runs $395 to $780 for a full-system cleaning of a standard single-family home, depending on the number of duct runs, system configuration, and whether you need add-ons like sanitizing or duct sealing. Most Redwood City ranch homes from the 1950s-60s with original sheet-metal ducts fall on the lower end, while Redwood Shores condos and newer builds with flexible ductwork and crawl-space access complications land closer to the top. Residential supply and return duct cleaning as a standalone job usually comes in at $145 to $240 per run set. Video inspection is $149, and we credit that fee toward the cleaning if you move forward the same visit. Commercial duct cleaning in Redwood City office parks and restaurant spaces is priced by square footage and system design; most jobs we quote in Redwood City fall between $900 and $2,800. Every price is written down before any work starts, and that written scope is what you approve. No exceptions, per Haven Standard Clause 1.

Our Air Duct Cleaning Services in Redwood City
Residential Duct Cleaning
Most Redwood City single-family homes we clean were built between 1955 and 1975. The original sheet-metal duct systems in these ranch homes were installed before anyone cared about sealing joints, so decades of Redwood City dust, pet dander, and cooking particulate accumulate in the runs. We clean the full system: supply plenum, return plenum, every supply run, every return run. The camera goes in first, and you see the before photos before we touch anything.
Commercial Duct Cleaning
Redwood City office buildings along Veterans Boulevard, restaurant kitchens on Broadway, and medical offices near Sequoia Hospital all run forced-air systems that circulate the same air for eight-plus hours a day. We use a commercial-grade negative-pressure extraction setup from Abatement Technologies for buildings with heavier buildup and longer duct runs. Our commercial pricing in Redwood City is quoted by system size and accessibility, with the written scope delivered before any crew arrives.
Supply Duct Cleaning
Supply ducts carry conditioned air from your furnace or air handler to each room. In Redwood Shores homes especially, these runs are often flex duct with interior moisture staining from the crawl space’s humidity. We see supply runs even in new Redwood City builds coated with drywall powder that the builder should have removed. Cleaning supply ducts means running agitation tools through every run, not just the first few feet past the register.
Return Duct Cleaning
Return ducts pull air back to the system, and they’re the first place pet hair, lint, and household dust settle. In Redwood City ranch homes, return runs often run through unconditioned attics where temperature swings have opened gaps in old sheet-metal joints. We photograph return runs separately from supply runs because the contamination patterns differ, and the fixes differ too.

Common Air Duct Cleaning Problems We See in Redwood City Homes
- New-construction gypsum dust in Redwood Shores builds: Builders run sheetrock sanding and textured wall work while the HVAC system is already installed, and few run a post-construction clean. The result is several pounds of fine white powder sitting in the supply and return runs, blowing through registers the week you move in.
- Moisture staining in crawl-space flex duct: Redwood Shores sits on filled Bay marsh with a water table only a few feet below grade. Even without a plumbing leak, the crawl space humidity wicks into duct boots that weren’t sealed. We routinely pull flex duct with dark interior staining and microbial growth in homes with zero visible water damage history.
- Original 1960s sheet-metal ducts in Rancho and Mount Carmel tracts: These systems were installed with basic friction-fit joints and no sealant. Fifty years of Redwood City thermal cycling has opened gaps at the elbows, which means the ducts pulling hot attic air into the cooling stream all summer.
- Shared duct chases in 1970s-90s Redwood Shores condos: Stacked and shared chases mean one unit’s cigarette smoke, cooking grease, or renovation dust can migrate into a neighbor’s ducts. Residential-grade equipment can’t reach these runs; commercial-grade negative pressure is required.
Pricing for Air Duct Cleaning in Redwood City, CA
Full-system air duct cleaning for a standard Redwood City single-family home runs from $395 to $780. The main variables are the number of supply and return runs, whether the ducts are accessible from a crawl space or attic, and whether the system needs sanitizing or sealing on top of the cleaning. Video inspection alone is $149, and we deduct that from your total if you approve the full cleaning the same visit. A new-construction Redwood Shores townhome where the builder left dust in the ducts usually lands around $500 to $700 because the flex duct needs more time and the crawl space access is tight. Commercial quotes in Redwood City start around $900. Every number is written down before any panel comes off. If you have a competitor’s written estimate, bring it in; we’ll put our own number next to it in writing, free of charge, under the Free Second Opinion policy. Call (806) 606-6902 and we’ll schedule the inspection.

FAQs - Air Duct Cleaning in Redwood City
Because most Redwood Shores builders do not pay for a post-construction duct cleaning before handover, despite running sheetrock sanding and finish work while the HVAC system is fully installed. The ducts become a collection point for drywall dust, paint overspray particulate, and construction debris, and that material starts circulating through your registers the first week you run the system. In Redwood Shores especially, this problem compounds because the flex duct also absorbs crawl space humidity, turning that dry dust into a caked layer that a standard filter will never catch. The fix is a full-system cleaning with agitation tools and negative pressure extraction, plus a camera inspection of every run so you can see what was left behind. We can usually clean a newly built Redwood Shores townhome in one visit. Call (806) 606-6902 for a written scope.
Redwood Shores stands on filled Bay tidal flats at near-sea-level elevation, with Bay water on three sides and a water table only a few feet below grade. That means the ambient humidity in crawl spaces and slab-adjacent chases stays persistently high, even in Redwood City’s famously sunny microclimate. In practice, we pull flex duct from Redwood Shores homes with dark moisture staining and microbial growth inside the runs, even when the homeowners report no leaks or water damage history anywhere in the house. Neighboring cities like San Carlos and Menlo Park don’t have this condition to the same degree because their housing sits on drier alluvial soil. If you live in Redwood Shores, insist on a video inspection that includes the crawl space side of the duct boots, not just the inside of the runs. We photograph all of it.
At minimum, the builder should have sealed the supply and return registers with plastic during sheetrock work, swept and vacuumed all duct runs after drywall sanding was complete, and performed a post-construction negative-pressure cleaning before turning the system over. Most don’t. A proper handover includes a photo record from inside the duct runs showing clean surfaces, but builders in Redwood City rarely provide this documentation. What we find instead is several pounds of gypsum powder resting in the return plenum and early supply elbows. That’s not acceptable in a new home, and it’s a fixable problem. We’ll document everything and deliver the photo record to you, so if you’re still in a warranty window with the builder, you have the evidence to take back to them. Call (806) 606-6902 if you moved into a Redwood City home in the last year and suspect construction dust is still in the system.
Yes, original 1960s sheet-metal ducts can be cleaned safely, provided the joints and seams are in reasonable structural condition. These systems are robust; the steel itself holds up fine. The problem we find in Redwood City ranch homes around Friendly Acres and Mount Carmel is that fifty-plus years of thermal cycling have opened gaps at the elbows, which makes the system pull in attic or crawl space air. We clean these ducts with rotating agitation brushes that won’t tear through old metal, working at controlled air pressure to avoid damaging the friction-fit joints. If the video inspection reveals significant gaps or disconnected sections, we’ll show you that on camera and recommend duct sealing as a follow-up scope, written separately and priced before work begins. Call (806) 606-6902 for an inspection and written price.
For most Redwood City homes, a full air duct cleaning every three to five years is the right interval, but there are two local conditions that justify a shorter cycle. If you live in Redwood Shores, the crawl-space humidity and water-table proximity create moisture conditions in flex duct that we recommend inspecting annually and cleaning every two to three years. If you recently bought a new build in Redwood City and never ran a post-construction cleaning, have it done once now to remove the builder’s dust, then settle into the regular schedule. The climate point that actually matters: Redwood City residents use both heating and cooling more than coastal Peninsula cities because this city runs warmer and sunnier year-round per long-standing meteorological records. More system hours per year means more air passes through the ducts, which means faster particulate deposition. It’s simple arithmetic. Call (806) 606-6902 and we’ll give you a written recommendation based on what the camera shows.
