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.

AfterFast, Reliable Air Duct Cleaning Across Los Altos
Air duct cleaning in Los Altos typically costs $450 – $850 for a standard single-family home, and the job usually takes three to five hours. We work in Los Altos regularly, from the Eichler tracts south of Foothill Expressway to the ranch neighborhoods near Loyola Corners and the larger custom builds off El Monte Road. Our Air Duct Cleaning crews know the duct layouts, attic profiles, and retrofit patterns specific to this city. Call (737) 727-2314 to book a visit with a written price before any work starts.
Why Cardinal Air Duct Cleaning Is Los Altos’s Preferred Air Duct Cleaning Company
Los Altos homeowners call us because we quote one flat price per system, not per vent. That’s a meaningful difference in a city where a 1962 ranch on a quarter-acre lot can have dramatically different ducting than a 2018 rebuild two streets over. A per-vent quote is practically a guess. We don’t play that game.
Our technicians arrive in uniform, background-checked, and with their names shared before they knock. The equipment is professional-grade: Rotobrush rotary brush systems, Nikro HEPA vacuums, and Abatement Technologies containment units. Not a shop vac. Our Los Altos customers also appreciate that every job includes before-and-after photos of their own ducts, taken during the work, not stock images. The 365-Day Done Right Promise backs every job: if the work isn’t right within a full year, we return and correct it at no charge.
Cardinal Air Duct Cleaning is part of the Relay Home Co. family, founded in 2005. Every booking runs on The Relay Standard: a live trackable arrival time, photo documentation, and a digital invoice payable by phone. Omar Haddad leads the team for this area.
Residential Air Duct Cleaning in Los Altos
Residential Air Duct Cleaning in Los Altos means working with a specific housing stock: mid-century Eichler and ranch homes with original galvanized ducting, plus a wave of recent heat-pump retrofits using flex duct in tight attic spaces. The job involves sealing registers, connecting a HEPA-filtered negative-pressure vacuum to the supply plenum, and mechanically agitating the inside of each duct run to break up caked dust, pet dander, and construction debris. We camera-inspect before and after. For a typical 1,800 – 2,600 sq ft Los Altos home, expect $450 – $750.
Eichler and Ranch Home Ductwork
Eichler homes in Los Altos, particularly in tracts along Fremont Avenue and near Heritage Oaks Park, were built with in-slab or attic ducting sized for heating only. When owners add AC or heat pumps, the original ducts are often undersized. Cleaning those systems requires careful negative-pressure work so loosened debris goes into the HEPA unit, not back through the registers into living space.
After a Renovation or Remodel
Los Altos sees constant renovation activity. Drywall dust, sawdust, and stray fasteners end up in duct runs during construction. If you’ve recently remodeled a kitchen or added a wing, schedule a cleaning after the contractors finish. The $450 – $750 range covers a full system clean including supply, return, and the air handler cabinet.
Commercial Air Duct Cleaning in Los Altos
Commercial Air Duct Cleaning in Los Altos serves offices, medical suites, and retail spaces along El Camino Real, San Antonio Road, and the downtown triangle near Main and State streets. The scope is different from residential: longer duct runs, rooftop package units, and higher occupant density. A small commercial space (2,000 – 5,000 sq ft) in Los Altos typically runs $800 – $1,500 depending on the number of rooftop units and accessibility from the roof hatch.
Offices and Retail
Employee complaints about stale air or uneven cooling often trace to dirty evaporator coils and blocked return plenums. We clean the full path: supply runs, return plenums, mixing boxes, and the coil. Work is scheduled around your operating hours so you don’t need to close down.
Medical and Dental Suites
Healthcare spaces in Los Altos have stricter indoor air expectations. HEPA-filtered extraction and Abatement Technologies containment keep dust from migrating to treatment rooms. We document everything with photos and provide a written report for your records.
Trusted Brands We Service in Los Altos
We work on duct systems tied to every major HVAC brand found in Los Altos homes: Carrier, Trane, Lennox, Rheem, and Mitsubishi heat-pump systems. For filtration upgrades, we install and service Aprilaire media cabinets, Honeywell electronic air cleaners, and Guardsman UV systems. Having local stock for common filter sizes and replacement flex-duct sections means we can often handle a repair during the same visit as the cleaning. If a supply run is torn or a return plenum has separated at the seam, we’ll quote the repair as a separate written line item before touching it.
Common Air Duct Cleaning Problems We See in Los Altos Homes
- Undersized ducts from forced-air heating retrofits. Many 1950s and 1960s homes in Los Altos added central AC decades after construction. The original ducts were never resized for cooling loads, so airflow is weak and dust settles faster in long, low-velocity runs.
- Rodent activity in attic ducting. Los Altos’s tree canopy and older construction create attic access points for rodents. Chewed flex duct, nesting debris in returns, and droppings are common findings during camera inspection.
- Flex duct kinks and tears in tight attics. The low-pitch roofs on Eichler and ranch homes leave little attic clearance. Homeowners and handymen retrofitting systems often kink or tear flex duct in the process, which leaks conditioned air into the attic.
- Dryer vent lint backup into the wall cavity. Older Los Altos homes often have long, vertical dryer vent runs that were never intended for modern high-efficiency dryers. Lint accumulates, airflow slows, and the dryer overheats. We clean these as part of a full visit.

FAQs About Air Duct Cleaning in Los Altos
Every 3 – 5 years for most Los Altos homes. Homes with pets, recent renovations, or occupants with allergies often benefit from every 2 – 3 years. If your home is an original-condition Eichler with ducting that has never been inspected, book a camera inspection first; you may not need a full cleaning at all. Call (737) 727-2314 and we’ll tell you honestly what we find.
Per system. We quote one flat price per air handler or furnace system before any work begins. Per-vent pricing in Los Altos is unreliable because a 10-register house can hide far more linear duct footage than the register count suggests, especially in retrofitted mid-century homes. The written price does not change at the door.
We seal every register, connect a Nikro HEPA vacuum to the supply plenum under negative pressure, then use Rotobrush agitation tools inside each run to loosen debris. Extraction is continuous, so loosened material goes straight into the HEPA unit, not into your living room. We then clean the return side, the air handler cabinet, and the evaporator coil, followed by a final camera pass.
Yes. Every job includes photo documentation of the actual ducts in your home before and after cleaning. You’ll see the inside of your own system, not a stock image. These photos come with your digital invoice, payable from a link on your phone.
If your dryer vent hasn’t been cleaned in the past year, yes. We routinely find significant lint buildup in Los Altos homes with long vertical vent runs, especially in older ranch homes. A clogged dryer vent is a fire hazard. We’ll inspect it during the visit and add a cleaning as a separate written line item only if you approve it.
Why a Per-System Price Matters in Los Altos
Much of Los Altos’s housing stock is mid-century Eichler and ranch homes built roughly between 1948 and 1965. Their original ductwork was sized and laid out for forced-air heating, not today’s AC and heat-pump upgrades. So duct runs are often undersized, flex-duct retrofits snake through tight attics, and the air handler closet is frequently the tightest space in the house. A company quoting by register count can’t account for any of that. We price by system, and we inspect the full duct path before we quote.
We ran a job near the Loyola Corners area of Los Altos where a 1960s ranch had been retrofitted with a heat pump and flex duct through a low attic; the customer complained that two back bedrooms never got cold. Our tech sealed the system and pulled it under negative pressure with a Nikro unit, then used camera inspection and agitation tools to break up decades of dust and rodent debris sitting in the return ducts. After source removal and recirculating everything through HEPA filtration, airflow to those two registers evened out and the blower motor was drawing closer to its rated load.
That’s what actually fixes a comfort problem in a Los Altos home. Not a coupon. Not a 45-minute shop-vac pass. Real source removal, documented with your own photos, backed for 365 days.
When You Don’t Need Duct Cleaning
Not every Los Altos home needs a cleaning right now. If your system was installed in the last two years, if you’ve already had a high-quality cleaning within the last three, or if you just changed your filter and airflow is fine, save your money. Where this changes: renovation dust, rodent activity in the attic, a sudden musty smell when the blower kicks on, visible dust puffing from registers, or a family member with newly worsened allergies. Those are real indicators. Call (737) 727-2314 and describe what you’re seeing. We’ll tell you if a cleaning is warranted or if you’re better off waiting.
