Does your HVAC feel tired? Rooms take too long to balance. Dust returns fast. Vents look gray. A faint musty puff hits at start-up. That is not “just old house air.” It is buildup inside your ductwork. Ductech delivers duct vent cleaning that is neat, measured, and friendly. We protect floors. We clean the entire air path. We verify results with photos and readings. We offer same-day service when the schedule allows. Workmanship includes a clear warranty. Our methods are eco-friendly and low-odor.
If you nodded yes to two or more, it’s time.
We clean supply trunks, branch runs, and return lines. We brush and vacuum both metal and flex duct. We remove and wash grilles. We tidy accessible plenums we open. We collect debris at the tool with HEPA equipment. No dusty “blow-and-go.” No harsh fog by default. On request, we can apply a low-odor, eco-friendly sanitizer for odor control. The result is real source removal. Not perfume.
Our 3-proof policy
Redwood Shores (94065). Long vertical runs to roof caps. Wind off the Bay. We build containment and stage noise around calls.

Friendly Acres & Fair Oaks. Tight closets and shared utility spaces. We keep paths safe and common areas tidy.

Why cleaning pays off
Short sentences. Real gains you can feel.
Care tips that help
Use quality filters and change on schedule. Keep supply and return paths unblocked. Leave a gentle curve on flex sections; no tight kinks. After drywall work, clean right away. If you add a room or move walls, ask us to re-balance dampers. Small habits, big results.
Scheduling cadence
Most homes: every 2–3 years.
Pets or allergies: 18–24 months.
After remodeling: immediately.
Moving in: clean once to set a baseline.
We will suggest a cadence based on your layout and our findings. No upsell. Just data.
Pricing that stays sensible
Homes and systems differ. Size, register count, access, and debris level set the scope. We walk you through the plan. We quote clearly. You approve before we start. If we see a surprise mid-visit, we pause and show photos first. No pressure.
Ductech serves all of Redwood City, including 94061, 94062, 94063, 94064 (PO Box), 94065 (Redwood Shores).
Laundry should finish in one cycle. If not, the dryer vent is likely choking airflow. Lint packs into elbows. Moist air compacts fibers into dense plugs. Exterior flaps stick. Sensors trip. The laundry room heats up. Our dryer vent cleaning clears the lint-trap cavity, the transition connector, all in-wall/ceiling runs, and the exterior hood or roof cap. We stage clean containment and capture debris with HEPA equipment. We free stuck dampers and confirm full travel in a live test. If parts are crushed or outdated, we can upgrade to UL-2158A semi-rigid connectors, proper clamps, and a code-compliant hood. Parts are original-spec and include a parts warranty. Most homes do well with yearly service; long or vertical runs may need every 6–9 months. For scope, timing, and booking, click here.
A clean chimney protects your living room and keeps draft strong. Soot and creosote narrow the flue and can ignite. Our chimney sweep cleaning covers the main flue, smoke chamber, and smoke shelf. We free sticky dampers and check the cap and crown from safe access. Debris is captured with HEPA filtration, so there’s no dust on rugs or sofas. You get photos, clear notes, and simple burn tips. Use seasoned wood. Warm the flue at start-up. Keep the damper fully open as the fire builds. Most homes schedule a sweep once a year; frequent burning may need every 6–12 months. Learn more here.
How long does a typical visit take?
Most homes take 2–4 hours. Complex layouts or heavy buildup can take longer. We confirm the window on arrival.
Will cleaning reduce dust on my shelves?
Yes. Removing debris from supply and return paths reduces particles that recirculate. You should see cleaner registers and less dust settling.
Do you use chemicals?
Not by default. We use mechanical agitation with HEPA capture. If you request sanitizer, we apply a low-odor, eco-friendly option.
Can you work in tight closets or multi-unit buildings?
Yes. Redwood City has many compact utility spaces. We use low-profile fittings and flexible tools. We keep common areas tidy.
Is this loud or messy?
Noise is moderate. We stage louder steps around calls or naps. We protect floors and collect dust at the tool. We show before/after photos.
How do I know when to rebook?
Watch for dust lines at registers, weak flow in one room, faster filter clogging, or that musty puff at start-up. Pets or remodeling? Rebook sooner.
