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.
Carrier Air Duct Cleaning in Los Altos, CA
Carrier air duct cleaning in Los Altos runs $425 – $685 for a whole-system clean, and it’s work we do independently, not through any Carrier dealership arrangement. The thing that makes Carrier duct work different in Los Altos is the housing stock: most of these 1950s – 1970s ranchers have been remodeled and expanded in pieces, which means the ductwork isn’t one clean original run but a patchwork of metal trunk lines and add-on flex that hides real problems. Neal Drummond and our crew work Carrier equipment specifically, and we serve all four Los Altos ZIP codes: 94040, 94022, 94023, and 94024. Call (833) 620-7085 and we’ll tell you what your system actually looks like before we quote a dollar.
Why Los Altos Residents Choose Us for Carrier Service
Most duct cleaners know how to run a vacuum through a register. Fewer know the difference between a Carrier Infinity 96 variable-speed blower and a WeatherMaker from the Carter administration, and what each one does to airflow when a return gets crushed in a low-clearance attic. We do. Neal completed his HVAC and building systems training through Foothill College’s program in Los Altos Hills, where we also provide Carrier repair, then spent over a decade working residential and light-commercial duct systems across the Peninsula before founding this company. The man has pulled enough mastic off old Carrier plenum collars to know exactly how they fail. When we quote a Los Altos job, we’re quoting from experience with the equipment in your attic, not from a chart.
We also stock OEM-equivalent Carrier blower and coil parts where fit matters, and quality aftermarket caps, collars, and mastic elsewhere. That means when we find a separated duct collar during a cleaning, we can often seal it the same day instead of telling you to call someone else. For Los Altos homeowners who want one provider from cleaning to repair, that’s the whole point.

Common Carrier Air Duct Cleaning Problems We Solve in Los Altos
Carrier equipment is solid, but the ductwork around it in Los Altos is rarely original anymore. Here’s what we run into, and why it happens here specifically:
- Carrier Infinity systems that run constantly but never satisfy the thermostat. The Infinity and variable-speed air handlers pull hard on return static. When a remodel-era flex return gets crushed or disconnected in a Los Altos attic, the blower compensates by running high-speed continuously and the house still feels uneven. We video-inspect the return path before cleaning so we’re not just vacuuming around a structural airflow problem.
- Original Carrier evaporator coils choked with Santa Cruz Mountains dust and wildfire ash. Los Altos sits in a dry Mediterranean pocket with long, dusty summers and a September – October fire season that pushes fine particulate through return grilles. Older Carrier coils in ranch homes collect that material on the fins, airflow drops, and the coil ices after moderate use. Cleaning the ducts without addressing the coil leaves the root problem in place.
- Rusted or loosened Carrier plenum connections from the 1970s. The mastic seam between a Carrier metal trunk and the plenum collar dries and fails after a few decades in a hot, low-clearance attic. Conditioned air leaks into the insulation and dust gets pulled back into the supply run. We see this constantly in original 1960s and 1970s ranchers across 94022 and 94024.
- Flex duct spliced into Carrier metal trunks during mid-century remodels that collapses or separates. Los Altos added square footage the way a lot of wealthy towns did: incrementally. A family expands the kitchen, adds a room off the back, and the HVAC contractor splices flex into the old Carrier trunk because it’s faster than replacing the run. That spliced section sags, crushes, or separates, and the new room never gets proper airflow.
- Buried duct runs hidden under blown-in insulation. This one deserves its own section below, because it’s the single biggest reason a cheap cleaning quote in Los Altos misses the actual problem.
Carrier Service in Los Altos: What Local Conditions Mean for Your Equipment
In the older ranch tracts off the 94022 and 94024 side of Los Altos, the original Carrier supply and return runs were laid across the attic floor in the 1960s and 1970s. Then someone added blown-in insulation during a remodel, buried the ductwork, and spliced new flex into the old metal trunks without documenting where any of it went. A walk-through cleaning estimate from a company that never enters the attic will give you a price, but it won’t tell you that a return trunk is crushed flat under twelve inches of insulation, or that a disconnected run is pulling attic dust directly into your supply side. That’s the information-gain we’re delivering here: in this town specifically, the ductwork hides below the insulation line, and the only way to map it is with video inspection and insulation clearing before cleaning. We do that on every Los Altos job. On a 1960s ranch off the 94024 side, a customer with a Carrier Infinity 96 furnace complained the system ran all afternoon without cooling. Our tech went into the low-clearance attic, cleared blown-in insulation off a Carrier metal trunk, found a crushed flex return spliced in during an old remodel, and ran video inspection through the whole system before cleaning, sealing the separated return, and reconnecting the plenum collar. After that, the blower cycled normally instead of running flat-out. The duct doesn’t lie – whatever has been moving through your air system for the past decade is still in there until someone actually removes it.
Carrier Models & Products We Service in Los Altos
We work on the Carrier equipment most common across Los Altos: the Performance series gas furnaces and air handlers with the FV/FX-style cabinets, the Infinity 80 and 96 gas furnaces with variable-speed blowers, the Comfort series split-system air conditioners with matching evaporator coils, and the older WeatherMaker and legacy furnaces still running in 1950s – 70s ranchers. The WeatherMaker units are the trickiest, because parts compatibility gets thin and previous homeowners often patched them with whatever a handyman had. On older Carrier equipment we favor honest repair when the coil and heat exchanger are sound, and we recommend replacement only when parts cost or airflow loss makes continuing pointless. For Los Altos turnaround, we keep OEM-equivalent blower and coil parts for the common Carrier cabinet layouts in our stock, so most jobs don’t wait on a freight order. We’re an independent service company, not a Carrier authorized dealer – which means we tell you what the equipment needs without a manufacturer sales quota coloring the recommendation. This is part of our broader Carrier sales & service work across the Peninsula.

AfterCarrier Service Pricing in Los Altos
Whole-system air duct cleaning in Los Altos typically runs $425 – $685 depending on the number of zones, access difficulty, and how much of the ductwork is buried under insulation. Attic-clearance issues, crawlspace-routed returns, and heavy contamination from wildfire smoke push toward the upper end. Duct sealing runs $180 – $420, video inspection is $120 – $260, filter media upgrades are $45 – $120 installed, and dryer vent cleaning is $90 – $160. Every estimate includes full attic access, video inspection where ducts are buried, and before/after photos of your actual system. We give one flat price per system agreed before work starts – not a per-vent figure that balloons once the van is parked. Call (833) 620-7085 for an exact quote on your Los Altos home; estimates are free and we’ll actually go into the attic before we give you a number.

FAQs – Carrier Air Duct Cleaning in Los Altos
Yes, and this is exactly what most companies skip. In 94022 and 94024 ranch homes, original Carrier supply and return runs were buried under blown-in insulation during later remodel work. If we don’t clear that insulation and run video inspection first, we can’t see crushed, disconnected, or spliced runs, and we’d be cleaning ducts that aren’t actually delivering air where they should. We clear, inspect, clean, and then reseat the insulation. Call (833) 620-7085 and we’ll walk you through what your attic layout likely looks like before we even visit.
Yes, often on the return side. Carrier Infinity and variable-speed blowers pull hard on return static, so a crushed flex return or a separated collar in your Los Altos attic forces the blower to run high-speed continuously without satisfying the thermostat. Dirty ducts compound the problem but the real culprit is usually airflow obstruction, which we find with video inspection.
It helps, but the full answer depends on where the smoke particles settled. In Los Altos, wildfire smoke from the Santa Cruz Mountains gets pulled through return grilles and deposits on the blower wheel, evaporator coil, and inside the supply runs. Cleaning the ducts removes the bulk of it, but if the Carrier coil itself is coated, the smell persists until the coil is cleaned too. We clean the full system including the coil when smoke contamination is present, not just the duct runs.
We do, regularly. The WeatherMaker line is common in 1960s and 1970s ranchers across Los Altos, and the ductwork around them is usually original metal trunk with later flex splices. We know the cabinet layouts and collar interfaces well enough to clean and seal them without damaging aged mastic seams. If a parted-out WeatherMaker coil or blower is at end of life, we’ll tell you plainly rather than sell you a cleaning that won’t hold.
Yes, and this is one of the most useful services we offer in Los Altos. When rooms were added piecemeal over the decades, contractors spliced flex into Carrier metal trunks without updating the zone layout. We video-inspect the full run, map where each branch goes, identify crushed or disconnected sections, and give you a documented before/after record. That documentation is something detail-conscious Los Altos homeowners expect, and we provide it on every job. Call (833) 620-7085 for an exact quote – estimates are free.
