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.
Air Duct Cleaning Company in San Mateo, CA
Air duct repair in San Mateo is a different job than it is ten miles south. We’re not just cleaning modern flex systems here. We’re often rebuilding or replacing the original sheet-metal ductwork in 1920s through 1950s bungalows and ranch homes, especially near downtown and Hayward Park, where decades of marine air, sagging joints, and undersized runs have taken their toll. If your San Mateo home still breathes through its original ducts, call us at (833) 620-7085 and we’ll tell you what’s actually inside them.
Why San Mateo Homes Are Different
San Mateo has some of the oldest housing stock on the Peninsula, and it shows up inside the ductwork. West of El Camino Real in the 94401 and 94402 ZIP codes, many homes date to the 1920s through the 1950s. Their ducts were often installed when forced-air heating was still a new idea, and plenty of them have never been touched since. We routinely see taped joints that dried out during the Reagan administration, sagging runs that have lost their slope, and return paths that pull air from a crawlspace instead of a conditioned room.
The marine climate does its own damage. Wet winters push moisture into crawlspaces and basements, and cool, salt-laden air accelerates corrosion on older galvanized metal. Then the dry season arrives and everything that settled during the winter gets pulled into the system and blown through the house. Spring cleaning and post-winter mold checks are the local rhythm here, and for good reason. Homes near the water in 94404, closer to Foster City, deal with a different version of the same problem: mid-century tract ducts that were undersized from day one and have spent sixty years accumulating dust.

Our Main San Mateo Services
Most San Mateo homeowners first call us for one of two reasons: the air in the house feels stale and dusty, or the dryer has started taking two cycles to dry a load. Both services lead with professional-grade equipment, not improvised tools.
Air Duct Cleaning in San Mateo
San Mateo homes collect a specific mix of debris: decades of dust, pollen from the tree-lined streets near Central Park, and fine marine air particles that settle into every low spot in the duct run. Our Air Duct Cleaning in San Mateo uses Rotobrush contact-cleaning systems paired with Nikro HEPA negative-air machines, so the particulates we dislodge get captured before they can drift back into your living room. Older ranch homes, especially those still running original ducts, respond dramatically to a full cleaning.

Dryer Vent Cleaning in San Mateo
Lint buildup is a fire hazard, and San Mateo’s older homes often have long, awkward dryer vent runs that were retrofitted decades ago. Every foot of that run is a place where lint can pack tight. Our Dryer Vent Cleaning in San Mateo is treated as a fire-prevention service, not a cheap upsell. We clean the full run from dryer to exterior termination, and we’ll tell you honestly whether the vent itself needs repair or rerouting.

Air Duct Repair in San Mateo
San Mateo’s oldest homes were built for gravity heat and later retrofitted for forced air. The result is often a patchwork: short, soot-lined plenums feeding undersized branches, return air pulled from wherever was convenient, and joints sealed with tape that gave up years ago. In the downtown San Mateo and Hayward Park neighborhoods, we regularly find original 1940s octopus gravity furnaces still connected to ducts that were never designed to move filtered air at modern pressures. Repair work here is less about patching a leak and more about restoring a system to functional condition. Air duct repair is a dedicated service for us, not an afterthought. Our Air Duct Repair work covers everything from isolated joint resealing to full branch replacement.
Ductwork Repair
Signs you need it
Rooms that never reach temperature, visible dust streaks around register edges, or a system that runs constantly without changing the feel of the house are the three most common San Mateo signatures of leaking or disconnected ductwork.
What it costs in San Mateo
Standalone ductwork repairs in San Mateo typically run $250 – $700 depending on access, with the oldest downtown homes skewing toward the top because the ducts are often buried in tight crawlspaces.
How we do it
We locate the leak with a visual inspection and pressure testing, then reseal the affected joints with mastic and mechanical fasteners, not tape.
Duct Replacement
Signs you need it
If the metal is corroded through, the ducts have collapsed in sections, or multiple joints have failed, replacement is almost always cheaper in the long run than repeated spot repairs.
What it costs in San Mateo
Full duct replacement in San Mateo generally lands between $2,000 and $6,500, with the spread driven by access difficulty, system size, and whether any return plenums need to be rebuilt.
How we do it
We remove the failed sections, size the new runs to the actual airflow requirements of the home rather than copying what was there, and seal every connection before the system is rebalanced.
What Air Duct Repair Costs in San Mateo
| Item | Typical range in San Mateo |
|---|---|
| Ductwork repair (single section) | $250 – $700 |
| Duct replacement (partial system) | $1,200 – $3,400 |
| Duct replacement (full system) | $2,000 – $6,500 |
How long does duct repair take in San Mateo?
Most isolated duct repairs in San Mateo finish in half a day, but older downtown homes with tight crawlspace access can stretch the job to a full day. We’ll give you a straight time estimate before we start.
Can you repair ducts without replacing the whole system?
Yes, and in San Mateo that’s often the right call. If the metal is sound and the problem is failed joints or sagging runs, we repair what’s there. We only recommend replacement when the ducts are functionally dead. Call (833) 620-7085 for an honest assessment.
Brands We Service in San Mateo
We work on Honeywell and Aprilaire filtration systems throughout San Mateo, cleaning and servicing the units as part of the job rather than treating them as an afterthought. We also install and maintain both brands when a homeowner wants air quality improved at the source. See our brands for the full list. Parts for common Honeywell and Aprilaire units are stocked on our trucks, so most filtration service calls in San Mateo are completed in a single visit.
