Air Duct Cleaning in Los Altos - One Flat Price, Before-and-After Photos

Fast, Reliable Air Duct Cleaning Across Los Altos

Air duct cleaning in Los Altos typically runs $450 – $900 for a full single-system home, and most jobs are completed in a single visit. If you live in a larger Los Altos property with two or three separate HVAC systems, each system is quoted and documented separately rather than folded into one misleading flat price. That’s the honest way to price this work, and it’s how we’ve always done it. Call (866) 528-3938 for a free estimate.

We know Los Altos homes because we work in them every week, from the mid-century ranchers off Foothill Expressway to the rebuilds near downtown. The housing stock here is different from Mountain View or Cupertino. It’s older, it’s custom, and the ductwork has usually been in place since the Eisenhower administration. That changes how a cleaning should be approached, priced, and documented.

Why Duct Cleaning Mountain View Is Los Altos’s Preferred Air Duct Cleaning Company

Los Altos homeowners call us because we show up with professional-grade Rotobrush and Nikro cleaning systems, not a shop vacuum strapped to a van. The equipment matters when you’re cleaning 50-year-old galvanized runs buried in a crawlspace. Consumer-grade tools can’t reach the full length of those ducts, and they don’t agitate decades of compacted dust and oak pollen off the walls. Ours do.

Our team works in Los Altos regularly, so we’re familiar with the specific failure modes here: rodent-damaged attic flex, collapsed runs behind air handlers, and dry-rot dust mixed into the return air. We also bring Abatement Technologies HEPA filtration on every job. That means what we dislodge from your ducts gets captured and contained, not blown back into your living room through the registers.

Dave Hanson, who leads our crew, has spent years working on the duct systems specific to this part of the Peninsula. When a Los Altos homeowner asks why their downstairs return is pulling oak pollen in August, the answer usually lives in the attic or crawlspace, not the filter. That’s the level of local knowledge we bring to every estimate.

Air Duct Inspection in Los Altos

Air Duct Inspection in Los Altos is the starting point for most of our jobs, because what’s inside a 1960s rancher’s duct system is rarely what the homeowner expects. We run a camera through the supply and return lines before any cleaning begins. In Los Altos specifically, this step matters more than in newer housing stock. Roof rats and squirrels have had fifty or sixty years to find their way into attic flex runs, and the damage isn’t visible from the register opening. A camera inspection finds it.

An inspection in Los Altos runs $150 – $300 depending on system count and access. It’s credited toward the cleaning if you book both. If you’re buying a home off Springer Road or near Los Altos Hills, an inspection before close tells you whether the ducts need cleaning, repair, or full replacement. Not all three. Just what’s actually there.

What the camera sees

We run a push camera from the register to the air handler and back on both supply and return sides. The footage shows us breaches, collapsed flex, debris accumulation, and whether the duct is even connected to the plenum anymore. In older Los Altos homes, disconnected runs are more common than most people would guess.

What you get afterward

You get a written report with still images and our recommendation. No pressure. If the ducts are cleanable and intact, we say so. If they’re torn open and full of rodent debris, you’ll see it on camera. That’s the whole point of the inspection.

Residential Air Duct Cleaning in Los Altos

Residential Air Duct Cleaning in Los Altos is a full-source-removal job, not a surface pass. We connect our Rotobrush or Nikro system to the main trunk line, seal the registers, and use negative pressure to pull dislodged material out of the system while agitating the duct walls. In Los Altos homes, that material is usually a mix of dry oak pollen, dust, construction debris from past remodels, and whatever the roof rats dragged in. It’s not humid mold, the way you’d see in a coastal climate. It’s dry, fine, and incredibly persistent.

For a standard single-system Los Altos rancher, expect to pay $450 – $750. A two-story custom home with separate upstairs and downstairs systems typically lands between $800 and $1,300. Each system is priced individually because each one takes time and consumes equipment wear. We don’t average three systems into one number and hope nobody asks questions.

Supply and return side cleaning

We clean both the supply and return ducting separately. The return side in older Los Altos homes is often the dirtier of the two, because it pulls from hallways and living spaces that have collected decades of dust. Skipping the return side is how a cheap cleaning leaves half the problem in place.

Video inspection after the work

When we’re done, we run the camera again and show you the before-and-after footage. That’s your proof the work was actually done, not just a receipt that says “cleaned.” If you can’t see inside your own ducts, the video is how you know.

Trusted Brands We Service in Los Altos

We carry Guardsman-brand vent covers and finishing products for Los Altos homeowners who want their registers sealed properly after a cleaning. We also work with Honeywell and Aprilaire filtration systems, and we can advise you on the right filter setup for a home that sits under mature oak canopy. If you already have an Aprilaire media cabinet or a Honeywell whole-home filter, we’ll clean around it and confirm it’s still performing. We don’t install units we haven’t been authorized to service, but we can point you to the right solution for your system. Los Altos homes with original ductwork often benefit from upgraded filtration, especially during Santa Cruz Mountains fire season when smoke settles over the valley for days.

Common Air Duct Cleaning Problems We See in Los Altos Homes

• Rodent-torn attic flex. Roof rats and squirrels in the attic spaces above Foothill Expressway and surrounding neighborhoods chew through flex duct and use it as a highway. A cleaning often reveals sections that need replacement, not just cleaning.
• Original 1950s galvanized trunk lines. Many Los Altos homes still run their original sheet-metal ducts through the crawlspace. These can be cleaned effectively, but they’re often leaking at the seams, pulling crawlspace air into the system.
• Dry oak pollen and leaf litter. Mature valley oaks and redwoods over the roofline drop constant debris that gets pulled into the return ducts. By late summer, a Los Altos return can be carrying a visible layer of yellow-brown pollen.
• Multiple HVAC systems on one property. Larger Los Altos lots often have a separate system for a guest wing or a second floor. Homeowners don’t always realize each system needs its own cleaning. A flat quote that ignores this usually means something got skipped.
