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.
Air Duct Cleaning Company in Alamo, CA
Air duct cleaning in Alamo costs between $450 and $1,450 for a whole-home system, with most single-family homes landing between $550 and $950 depending on the number of zones and the age of the ductwork. Alamo is one of the more demanding cities in the San Ramon Valley for duct work: the homes are big, the valley traps heat and pollen, and the Diablo winds carry silicate dust into return-air pathways faster than most homeowners realize. Morton’s Air Duct Cleaning serves families throughout Alamo with written pricing before any work starts, and our crews know the housing stock here well. Call (323) 918-4345 for a free estimate on any duct or vent job in Alamo.
Why Alamo Homes Are Different
Alamo sits in a topographical bowl, hemmed in by the Las Trampas Regional Wilderness on the west and the Mount Diablo foothills on the east. That geography does two things to a home’s ductwork. First, it concentrates the valley’s dry annual grasses and oak pollen into the local air, which means the material pulled into return ducts is denser and finer than what coastside communities ever see. Second, the seasonal Diablo wind events that sweep down from the northeast drive silicate dust and wildfire smoke particulates straight into attic and crawlspace duct runs, particularly in homes along Stone Valley Road and the properties backing up to the wilderness boundary.
The housing stock compounds the issue. Most Alamo homes were built between the late 1960s and the 1990s, with a large share in the 3,000 to 6,000-plus square foot range. These are multi-zone systems with long duct runs. Homes built before the mid-1980s often still have original fiberglass duct board interiors, and after forty years that material begins to degrade and shed fine particles into the airflow. When our techs clean a 1980s-era Alamo home, they typically pull out a combination of grass seed fragments, oak pollen, and fiberglass board dust that a standard filter swap will never touch. It’s not that Alamo homes are dirtier than elsewhere; it’s that the valley, the wind, and the age of the homes create a specific mix that requires a deeper, methodical clean.
Our Main Alamo Services
Alamo homeowners reach out to us for two jobs far more than anything else: whole-home air duct cleaning and dryer vent cleaning. Each has its own dedicated Alamo page below, where we walk through local pricing, what the job looks like in a typical Alamo house, and what to expect before, during, and after the work.
Air Duct Cleaning in Alamo
Whole-home duct cleaning in Alamo typically runs $450 to $1,450, with multi-zone systems on the higher end. The work involves cleaning every supply and return duct, the trunk lines, the air handler, and the return plenum, using professional equipment from brands like Nikro and Abatement Technologies. In Alamo specifically, the June grass die-off on the open-space hills means dried grass seed fragments end up inside duct runs, especially in homes backing up to Las Trampas or along the Stone Valley Road corridor. Those fragments are a clue that return-air leakage exists somewhere in the attic or crawlspace, and we’ll point that out while we work. Get the full breakdown on our Air Duct Cleaning in Alamo page.

Dryer Vent Cleaning in Alamo
Alamo’s generous lot sizes and larger floor plans mean dryer vents are often longer and more complex than in denser cities, frequently running through exterior walls or up through roofs. That extra length gives lint more surface area to accumulate, and in a valley where the air is already heavy with fine particulate, clogged vents compound quickly. We use professional equipment, including Nikro and Rotobrush systems, to clear the full run from the dryer to the outside termination point. Families with pets notice faster lint buildup, and larger households doing daily laundry benefit from an annual check. See full pricing and process details on our Dryer Vent Cleaning in Alamo page.

FAQs About Air Duct Cleaning Company in Alamo
Most Alamo jobs are scheduled within two to five business days. We coordinate scheduling and dispatch from our San Francisco Bay Area office and serve Alamo residents locally. Call (323) 918-4345 and a live person will give you a specific arrival window for your street, not a generic slot.
For air duct and dryer vent cleaning inside your home’s envelope, no permit is required by the Town of Alamo or any HOA we’ve worked with. The work is non-structural. If your dryer vent terminates on the exterior of an HOA-governed property, we’ll put down shoe covers and floor protection, and we’ll leave the termination point exactly as we found it, clean and secured.
In our experience, yes. The combination of valley grass and oak pollen, Diablo wind dust, and long summer HVAC runtimes means Alamo systems collect particulate faster than coastal East Bay cities. Most Alamo homes do well with a full duct cleaning every three to five years, and more often if the home backs up to open space or had smoke infiltration during wildfire season. Call (323) 918-4345 and we’ll help you figure out the right interval for your specific home.

What Alamo Customers Say
"New house, old dusty ducts. They were gentle in the house, laid down drop cloths, and double checked every register was sealed back up. Air smells fresh now."
- Scott Hemmings"Friendly, calm crew that clearly cared about the house. Covered their shoes, protected the floors, and double checked they'd closed up every vent cover properly. Would have them back."
- Omar Zaid"Ducts and dryer vent both. They put runners down the whole hall and wore booties. Spotless after, and they showed me photos of what came out. Worth every penny."
- Bonnie Vo
