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.

Why Morton’s Air Duct Cleaning Is Los Altos’s Preferred Air Duct Cleaning Company
We’ve been part of the Cedarwell family since 2005, and our reputation in Los Altos is built on one thing: doing what we said we’d do, at the price we said we’d do it, and leaving the house cleaner than we found it. Los Altos homeowners mention the same details in their feedback - that our technicians noticed the sleeping toddler and worked quietly, that the written price matched the final invoice, that the photo at the end showed a floor with no boot marks.
Response time to Los Altos neighborhoods like North Los Altos, South of El Monte, and the rural west side along Page Mill Road is typically two to four days for standard scheduling, not weeks. We know that homes near the Foothill Expressway corridor differ from those tucked against the Santa Cruz Mountain foothills, and we adjust our approach accordingly. The rural properties on unpaved roads need different filter recommendations and more thorough branch-line cleaning than the tighter subdivisions closer to downtown. That local knowledge means we don’t walk into your home with a one-size-fits-all checklist.
HVAC Duct Cleaning in Los Altos
HVAC Duct Cleaning in Los Altos means addressing a specific set of conditions you won’t find in neighboring cities: wildfire smoke particulates from the Santa Cruz Mountain fire corridor, original 1950s-1970s ductwork in hot attics, and on the rural edges, fine dust from unpaved roads and open land that standard filters simply don’t catch. A typical full HVAC duct cleaning for a Los Altos home runs $550-$850, depending on system size, accessibility, and whether we’re treating multiple air handlers including detached ADUs.
Our process starts with a video inspection so you see what we see. We then seal and pressurize the system, agitate built-up debris with rotary brushes, and extract it under negative pressure with HEPA filtration on the exhaust - critical in Los Altos, where deteriorating duct board at branch seams can release fiber if not properly contained. The 365-Day Done Right Promise applies to every job.
Smoke-Season Deep Cleaning
After major fire events like the 2020 CZU Lightning Complex, Los Altos homes - especially those with original unlined sheet-metal systems - retain smoke residue that standard filter changes won’t touch. We target return-air trunks and filter housings where dark staining concentrates, using Abatement Technologies HEPA equipment to capture particulates rather than redistribute them.
Multi-System Properties
Many Los Altos homes now have detached ADUs, garage workshops, or outbuilding studios with separate air handlers. These secondary systems get skipped on single-system quotes, meaning wood-heat particulates or shop dust keep cycling into the main house. We price each system separately and clean every connected run.
Vent Cleaning in Los Altos
Vent Cleaning in Los Altos addresses the supply and return registers, grilles, and visible duct openings where homeowners notice problems first - the dark-stained return grille, the supply vent that barely moves air, the musty smell that hits when the system kicks on. A focused vent cleaning runs $180-$340, though most Los Altos homeowners bundle it with full system work for better value.
We remove each register, clean the boot and first few feet of duct behind it, and treat the grille itself - not just a surface wipe, but actual removal of the accumulated loading that causes staining and odor. For homes in the smoke corridor, this is often where the 2020 fire season still shows.
Register-Level Odor Removal
Smoke particulates and fine dust bind to the textured surfaces of older metal grilles and plastic registers in ways that household cleaners won’t touch. We use rotary tools and contact vacuums at the vent opening, then finish with a pet-safe treatment where appropriate.
Airflow Testing After Clean
We measure before and after airflow at each vent with a digital anemometer. In Los Altos ranch homes with long branch runs, restricted airflow at distant bedrooms is common - the cleaning helps, and the numbers show you by how much.
Trusted Brands We Service in Los Altos
Our crews arrive with Rotobrush rotary agitation systems, Nikro negative-pressure extractors, and Guardsman surface treatments - not rental gear from the hardware store. For Los Altos homes with integrated air quality equipment, we stock filters and components for Honeywell, Aprilaire, and Abatement Technologies systems, which means faster turnaround when your media filter or UV bulb needs replacement during the same visit. We don’t have to order parts and come back. That matters when you’re scheduling around work-from-home calls and school calendars.
Common Air Duct Cleaning Problems We See in Los Altos Homes
- Smoke-stained return systems from wildfire seasons. Original 1960s sheet-metal trunks and unlined duct board in Los Altos ranch homes show heavy dark staining at return grilles and filter housings that correlates directly with major fire years - a pattern our technicians rarely see in newer Sunnyvale construction just east.
- Fine dust loading in rural properties on unpaved roads. Homes along Page Mill Road and the rural west side pull in particulates that bypass standard pleated filters and settle in low-velocity branch runs, requiring more thorough agitation and longer extraction times than city-subdivision standards.
- Crumbling duct board disturbed during cleaning. The hot attic spaces common in Los Altos’s 1950s-1970s housing stock bake duct board until it deteriorates at seams; without HEPA filtration on the exhaust, agitation releases fiber into the very air being cleaned.
- Skipped secondary systems on outbuildings and ADUs. Detached units with separate air handlers get left off single-system quotes, so wood-heat particulates, construction dust from recent renovations, or shop debris keep circulating back into the main house through open windows and foot traffic.
Pricing for Air Duct Cleaning in Los Altos, CA
A typical residential HVAC duct cleaning in Los Altos runs $550-$850 for a full system with one air handler. Vent cleaning alone is $180-$340. Homes with multiple systems - main house plus detached ADU, garage workshop, or outbuilding studio - add $350-$550 per additional air handler. What moves you within that range: total linear feet of ductwork, number of registers (we’ve seen Los Altos ranch homes with 20+ vents), accessibility of the air handler and trunk lines, and whether we’re addressing heavy smoke-season loading that requires extended HEPA extraction time.
We give you one flat price per system, agreed in writing before work starts. No per-vent pricing that balloons on the invoice. No surprise charges for “extra” registers or “deeper” cleaning. The price we write down is the price you pay. Call (323) 918-4345 for a free estimate - we’ll ask about your home’s age, location within Los Altos, and any recent fire seasons or renovation work, then give you a range you can plan around.

FAQs About Air Duct Cleaning in Los Altos
Every 2-3 years for rural Los Altos properties on unpaved roads or open land, compared to 4-5 years for tightly built newer subdivisions closer to downtown. The combination of wildfire smoke from the Santa Cruz Mountain corridor, fine dust from unpaved access roads, and pollen from open space means filters and ducts load faster here than in cities further east. Call (323) 918-4345 and we’ll assess your specific location and system age.
The staining is typically smoke particulate from wildfire seasons, especially in homes with original 1960s sheet-metal or unlined duct board systems that trap and hold fine particles filter media can’t catch. Standard 1-inch pleated filters are rated for household dust, not wildfire smoke. We see this pattern consistently in Los Altos homes west of El Monte Road, far less often in newer construction east of the Foothill Expressway.
Yes, and we price each system separately so nothing gets skipped. Many Los Altos renovation projects added ADUs or converted garages with separate air handlers; if we only clean the main house, wood-heat particulates or shop dust from the secondary system keep cycling into your living space. We treat every connected duct run.
No. Proper duct cleaning seals the system, pressurizes it under negative pressure, agitates debris with rotary brushes throughout the trunk and branch lines, and extracts with HEPA-filtered equipment - not a shop vacuum at the register. In Los Altos, we also run video inspection before and after, and we use HEPA exhaust filtration specifically because deteriorating duct board in older attic systems can release fiber during agitation.
Original sheet-metal ducts can almost always be cleaned, and they’re often more durable than the duct board that replaced them in later decades. The question is whether they’re unlined (common in 1960s Los Altos ranch homes) and whether seams have opened. We inspect with a camera first. If the metal is intact, cleaning removes the smoke and dust loading without disturbing the system. If seams have failed or rust is present, we’ll show you and discuss repair options - no pressure, just what we found.
