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.

AfterAir Duct Cleaning Company in Alamo, CA
Alamo sits in a wind corridor that most of the Bay Area never feels. Homes here back up to oak-grassland ridges leading toward Mount Diablo, and every fall the Diablo winds push dust, pollen, and sometimes wildfire ash straight into HVAC intakes. The result: ducts that load up faster than any coastal city 20 miles west. Our crews know exactly what Alamo’s housing stock does to ductwork, from original 1960s fiberglass duct board in the older ranch homes to multi-zone systems in the hillside estates. If you need a straight answer on what cleaning costs and what your ducts actually contain, call (469) 972-3151 and we’ll tell you before you ever book.
Why Alamo Homes Are Different
Alamo runs hot. Summer highs cross 100°F routinely from June through September, so central air conditioning runs nearly nonstop for four straight months. The dust and pollen load that accumulates in a single Alamo summer would take two years to build in Walnut Creek or Lafayette. Then September and October arrive, and the Diablo winds add a second layer: dry grass debris, fine soil from the open-space hillsides, and in active fire years, a measurable ash coating inside supply plenums. We’ve opened ducts along the hillside streets near Las Trampas Regional Wilderness and found a visible gray film lining the supply plenum interior, evidence that smoke bypassed a filter during a pressure surge.
The housing stock compounds it. Alamo’s 1960s and 1970s ranch homes frequently still run original fiberglass duct board or early flex duct, material that sheds fibers and traps debris in ways modern sheet metal never does. The large-lot horse properties add another factor: return-air grilles often sit near exterior entries or barn-adjacent structures, pulling in hay dust and animal particulates at rates denser suburban streets never see. And the 1990s and 2000s custom estates, many pushing 4,000 to 7,000 square feet, run multi-zone HVAC systems where one dirty plenum feeds half the house. None of this is generic duct cleaning. It’s Alamo.
Our Main Alamo Services
Alamo homeowners call us about two things most often: the ducts carrying heated and cooled air through the whole house, and the dryer vent that carries lint and heat out of the laundry room. Both are covered by the same written-price, written-guarantee standard.
Air Duct Cleaning in Alamo
Summer after summer of nonstop AC use leaves Alamo ducts carrying a layer of dust, pollen, and often ash that no filter change ever touches. We use Rotobrush rotary brush agitation to dislodge debris at the duct wall, then Nikro negative-pressure extraction pulls it out without pushing it into your living space. It’s the difference between sweeping a floor and vacuuming it properly. Older ranch homes with original fiberglass duct board need particular care, and that’s where the experience shows. Air Duct Cleaning in Alamo covers the full process and pricing.
Dryer Vent Cleaning in Alamo
Lint bypasses the trap in every home, but Alamo’s long dryer vent runs, especially in ranch homes where the laundry sits far from an exterior wall, collect it faster. A partially clogged vent means longer dry times, higher energy use, and a real fire risk. We clean the full run from dryer to exterior cap, not just the first few feet, and we clear the lint trap bypass area that most box-store tools miss. Dryer Vent Cleaning in Alamo explains what the job involves and what it costs.

Pricing for Air Duct Cleaning Company in Alamo, CA
Alamo pricing breaks down by home size and system complexity. Here’s what you can expect before a single vent is touched.

What pushes cost up in Alamo is system age and access. Original fiberglass duct board in a 1968 ranch takes longer to clean properly than modern sheet metal, and multi-zone estates mean more runs and more time on site. Whatever the number, it’s a written price in your hands before work starts, no door-step revisions.

What Alamo Customers Say
"Our dryer was taking two cycles to dry a load. They cleaned the vent and pulled out a frightening amount of lint. Dries in one cycle now and honestly I feel better about the fire risk."
- Marcus Lee"Set up an appointment for the whole house plus the dryer line. They called the morning of to confirm, showed up in the window, and showed me pictures of the gunk they pulled out. Worth it."
- Terrence Boyd"My wife's allergies were awful every morning. Had the ducts done and it's made a real difference. Tech was on time and wore booties in the house without me asking."
