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.
Fast, Reliable Air Duct Repair Across Los Altos Hills
Air duct repair in Los Altos Hills typically runs $450 – $1,400 for a standard repair, while full duct replacement in a large estate home can reach $4,000 – $12,000 depending on linear footage and accessibility. Most jobs take one day. That’s the honest range before we even set foot on your property.
We know these hills. The winding roads off Page Mill and the long driveways up from Moody Court aren’t new territory for us. Linden Air Duct Cleaning has been crawling through the crawl spaces and attic chases of Los Altos Hills homes long enough to know exactly what we’ll find before we open the first access panel. If you’ve got a crushed duct run, a disconnected return, or smoke odor that won’t leave your vents, call (980) 447-2498. We’ll give you a written price before any work begins.
Why Linden Air Duct Cleaning Is Los Altos Hills’s Preferred Air Duct Repair Company
Los Altos Hills homeowners don’t hand out keys to just anyone. We get that. You’re often home alone, or you’ve got young kids, or you’ve lived here forty years and you don’t want strangers wandering your property. That’s why every Linden technician is background-checked, identity-verified, and photo-badged. Before the visit, we send you the tech’s name and photo. At the door, they show you the same badge. That’s the Threshold Standard, and it’s not a marketing phrase. It’s our operating rule since 2004, under the leadership of Marcus Veale and the Threshold Group family.
We also know the housing stock here. Most companies send a tech who’s never seen a stamped-metal duct from 1969. Ours have. They’ve worked the custom ranches along Robleda and the contemporary builds off Fremont Road. They understand how a 40-foot duct run through an unconditioned crawl space behaves differently from anything in a Sunnyvale tract home. When you call, a live person answers. Always. No voicemail tree. Just a human who can schedule your Air Duct Repair visit and answer questions about what to expect.
Ductwork Installation in Los Altos Hills
Ductwork Installation in Los Altos Hills is less common than repair, but when you need it, you usually need it badly. We’re talking about homes where the original flex duct from the 1980s has collapsed, or where an addition built in 1995 left the system unbalanced and now pulls ash from the crawl space every time the AC kicks on. A full ductwork installation in Los Altos Hills typically runs $4,000 – $9,500 for a 3,000 – 4,500 square foot single-story estate, depending on how much of the run goes through unconditioned space. And that price is in writing before a single sheet of metal gets cut.
What Replacement Actually Involves Here
Older Los Altos Hills homes rarely have accessible duct runs. The chases are tight. The crawl spaces under these 1960s ranches sit on sloped grade, which means our installers often work in sections. We size the new duct to the existing air handler, seal every joint with mastic, and pressure-test the system before we call it done. It’s real work. It takes a full day, sometimes two.
When To Choose New Ductwork Over Repair
If your ducts are original stamped-metal from the late 1960s and they’ve rusted through in multiple spots, patching them isn’t an honest fix. Same goes for flex duct that’s been crushed flat by rodents or sloppy foundation work. In those situations, we’ll tell you straight: new ductwork is the better investment. And we’ll show you photos of what we found before we recommend a dollar figure.
HVAC Duct Installation in Los Altos Hills
HVAC Duct Installation in Los Altos Hills often means re-routing supply and return lines after a remodel, or upgrading an under-sized system that’s struggled with the smoke load this area brings. The cost typically lands between $3,800 and $11,000, depending on the number of runs, the difficulty of the attic or crawl access, and whether we’re also replacing the plenum or transition fittings. We use Rotobrush and Nikro equipment for cleaning and prep, and we stock common duct sizes in our Bay Area supply chain so Los Altos Hills jobs don’t stall waiting on parts.
New Drops, New Returns, Better Airflow
Sometimes the fix isn’t the trunk line. It’s adding a return in the master suite so the system stops pulling from the hallway. Or adding a dedicated drop to a far bedroom that’s always ten degrees off. HVAC duct installation here frequently involves correcting those pressure imbalances, which matter more in these long single-story ranches than in multi-story builds.
Replacing Flex With Rigid Pipe
Flex duct is fine when it’s installed well. In Los Altos Hills, it often wasn’t. We regularly see sagging, kinked, or flattened flex in slab chases where the concrete pour was tight. In those situations, we recommend rigid pipe where possible, or properly tensioned and supported flex where rigid won’t fit. The goal is a system that moves air evenly, not one that leaks 20% of your conditioned air into the dirt under your floor.
Trusted Brands We Service in Los Altos Hills
We don’t push one brand. We service what’s actually installed in these hills, which means you’ll see us working with systems built around Honeywell and Aprilaire components for filtration and humidity control. We use Guardsman products for coil cleaning and maintenance, and our extraction equipment comes from Rotobrush and Nikro. Because so many Los Altos Hills homes run these same brands, we keep the common parts and filters in stock locally, so we’re not waiting on a truck from Sacramento when your job is scheduled. Fast turnaround isn’t a slogan. It’s logistics.
Common Air Duct Repair Problems We See in Los Altos Hills Homes
- Disconnected or cracked stamped-metal ducts in 1960s – 1970s ranch homes. The original ducts along Moody Road and the upper Robleda corridor were installed before current sealing standards. Fifty years of thermal expansion and shifting foundation footings have pulled joints apart. We find 2 – 4 separations on a typical first inspection.
- Crushed flex duct in slab chases. These 1-acre lots often dictated unusual foundation layouts. We see flex runs flattened by foundation settling or by later plumbing and electrical work in the same chase. The result is a room that never cools properly and a system that pulls outside air in.
- Wildfire smoke coating on duct interiors. The 2020 CZU Lightning Complex fires deposited fine particulate into thousands of Los Altos Hills homes. Standard filter changes can’t remove what’s already deeper in the ductwork. Repair here means cleaning to NADCA standards, then sealing the leaks that let smoke in the first place.
- Pressure imbalances from long, undersized runs. Large estate homes with 3,000+ square feet of conditioned space often run ducts 40 feet or more from the air handler. When the trunk is undersized, the far rooms starve. We correct this by adding secondary returns or re-balancing dampers, not by just cleaning the blower again.

FAQs About Air Duct Repair in Los Altos Hills
Why do air ducts in Los Altos Hills need repair more often than in nearby Sunnyvale or Mountain View?
Because the housing stock is older and the terrain is different. Los Altos Hills developed as custom single-family estates from the late 1950s through the 1990s, and many of those homes still have original stamped-metal ducts from the 1960s and 1970s. Flat valley cities like Sunnyvale and Mountain View have newer tract housing with more accessible duct runs and less exposure to sloped crawl spaces. Add the wildfire smoke load from the Wildland-Urban Interface, and the repair frequency climbs. Call (980) 447-2498 to schedule an inspection.
How does wildfire smoke from events like the 2020 CZU Lightning Complex affect my ductwork?
Wildfire smoke carries fine particulates that get pulled into your return system and coat the inside of your ducts. Once inside, they stick to the walls of the ductwork, especially where the ducts run through cool unconditioned crawl spaces. The 2020 CZU Lightning Complex fires parked smoke over Los Altos Hills for weeks, and many homes still carry that residue. Cleaning alone can’t fix the problem if the duct leaks keep letting outside air in. Repair and sealing are often the real fix. We’ll show you camera footage before and after.
Can you repair original stamped-metal ducts from the 1960s and 1970s, or do they need full replacement?
It depends on the condition, and we’ll tell you honestly. Stamped-metal ducts from that era can often be repaired with new mastic sealing, re-supported hangers, and replacement of badly rusted sections. But if the metal has rusted through in multiple places or the joints have separated across long runs, replacement is the smarter investment. We don’t sell replacement for the commission. We show you the photos and explain the options. The written estimate covers whatever you choose.
What signs indicate my Los Altos Hills home needs duct repair rather than just cleaning?
Rooms that never reach the thermostat temperature are the most obvious sign. That points to pressure loss, not dirt. A smoky or musty smell that returns within weeks of a cleaning means outside air is entering the system somewhere. Visible dust on vents or furniture right after a cleaning, higher-than-expected energy bills, and rattling or flapping sounds from the attic or crawl space are other indicators. Any of these is worth a camera inspection. Call (980) 447-2498 for a free estimate.
How does the local climate and pollen from open-space preserves impact duct repair decisions?
Los Altos Hills gets marine-layer fog pushing east off the Santa Cruz Mountains more persistently than the valley floor, plus heavy oak and grass pollen from Rancho San Antonio and the Foothills Preserve. That moisture and pollen load settles on duct interiors and inside the air handler. If your ducts aren’t sealed, the system also draws in whatever’s in the crawl space. So repair decisions here always include checking the seals and the filtration. A clean but leaky duct system just pulls the same contaminants back in. We’ll recommend sealing as part of any repair where it’s needed.
