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.

AfterAir Duct Cleaning Company in Mountain View, CA
Air duct cleaning in Mountain View typically costs $350 – $650 for a whole-home system and is scheduled by appointment with a written price locked in before work begins. Mountain View’s mix of original 1950s Eichler homes, postwar ranch slabs, and newer North Bayshore infill means every job starts with a different set of duct conditions, from brittle galvanized steel embedded in concrete to complex chases in tight townhome envelopes. We dispatch from our San Francisco Bay Area office and serve Mountain View with Rotobrush rotary brush systems and Nikro negative-air machines, backed by the 365-Day Done Right Promise on every job. Call (361) 326-5060 for a free estimate.
Why Mountain View Homes Are Different
Mountain View sits at the northern end of Silicon Valley, where the Santa Cruz Mountains foothills create a seasonal inversion layer that traps wood-smoke, traffic particulates, and wildfire haze against the valley floor. That geography alone changes what we find in ducts here compared to open-coast cities.
The housing stock tells the rest of the story. Waverly Park and Monta Loma neighborhoods are dense with original Eichler and ranch-style homes built from the 1950s through 1970s, most on slab-on-grade foundations with low attics or no attics at all. Their original rigid galvanized ductwork is now sixty-plus years old, brittle at the joints, and often routed through unsealed crawlspaces or embedded directly in the slab. When we open those systems, we regularly find silica dust from decades of renovation and ADU construction, plus rodent debris in crawlspace runs that standard franchise crews never inspect.
Newer townhomes along North Bayshore and downtown high-rise condos present the opposite problem: tighter, more complex duct chases with limited access points, where a rotary brush system sized wrong for the chase can damage flexible duct or leave whole branches uncleaned. Mountain View’s mild Mediterranean climate means HVAC runs year-round for both heating and cooling, so accumulation is continuous, not seasonal. Spring pollen from the Santa Cruz Mountains and summer wildfire smoke events push more residents to treat duct cleaning as an indoor-air-quality repair rather than routine maintenance.
Our Main Mountain View Services
Mountain View homeowners call us most often for these three services, each with its own local conditions and equipment requirements.
Air Duct Cleaning in Mountain View
We clean supply and return ductwork with a two-stage approach: rotary brush agitation to knock debris loose from duct walls, followed by negative-air extraction to pull it out of the system. In Mountain View’s older Eichler and ranch homes, we start with a pre-cleaning camera inspection because slab-embedded or crawlspace duct runs can harbor decades of silica dust that standard negative-air cleaning alone won’t address. We use HEPA containment when needed and explain what we find before we start. Air Duct Cleaning in Mountain View
Dryer Vent Cleaning in Mountain View
Dryer vent blockages are a leading cause of house fires, and Mountain View’s older homes often have original vent runs that are too long, too many elbows, or terminate in inaccessible crawlspaces. We clear the full run from dryer to termination, inspect for proper airflow, and flag any code issues we find. In condos and townhomes with shared vent chases, we coordinate with building management when needed. Dryer Vent Cleaning in Mountain View
Duct Sealing in Mountain View
Leaky ducts in Mountain View’s aging housing stock waste conditioned air into crawlspaces, attics, and wall cavities. We seal accessible joints and seams with mastic and reinforced tape, then pressure-test to verify results. For homes with original galvanized ductwork, sealing often reveals how much airflow has been lost to corrosion gaps, which helps homeowners decide whether cleaning alone is enough or partial replacement makes more sense.
