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 Moraga, CA
Air duct cleaning in Moraga typically runs $450 – $850 for a whole-home system, with most jobs scheduled within a few days and completed in three to five hours. Moraga’s canyon-and-ridge topography and older housing stock make this work different from neighboring towns: homes here pull in heavy spring oak pollen and summer wildfire ash that settles deep in ductwork, and many systems were built before modern filtration standards. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and we serve Moraga with written prices before any work starts, background-checked uniformed technicians, and a 365-Day Done Right Promise backed in writing. Call us at (361) 326-5060 for a free estimate.
Why Moraga Homes Are Different
Moraga sits in a sheltered valley east of the Oakland Hills, and that geography changes what we find when we open a vent cover. Hot, dry summers and periodic Diablo wind events push wildfire smoke and ash from surrounding wildland-urban interface areas straight into home HVAC intakes. After a red-flag warning or nearby grass fire, our crews see a spike in calls because fine ash penetrates even closed windows and settles in return-air plenums. Spring brings intense oak and grass pollen from the surrounding hills, which accumulates quickly in return ducts.
The housing stock compounds the problem. Moraga’s homes are dominated by 1960s – 1980s single-story ranch homes and split-levels, many with original rigid metal ductwork that has developed leaks at joints over decades of seismic settling. These older systems were built before modern filtration standards, so they pull in outdoor debris rather than filtering it. Newer hillside custom homes often have complex, multi-zone duct systems that are harder to access and clean thoroughly. In both cases, duct cleaning in Moraga is less about ordinary dust and more about wildfire-smoke and pollen remediation.
Our Main Moraga Services
Most Moraga homeowners call us for one of three jobs. Each has its own page with full details on how we handle local conditions.
Air Duct Cleaning in Moraga
We clean supply and return ducts, registers, and the main trunk lines using a rotary brush system from Rotobrush combined with negative-air extraction from Nikro. In Moraga, we pay special attention to pollen and ash buildup in return plenums after wind events, and we inspect for seismic joint separation common in ranch homes built in the 1960s and 1970s. Every job gets a written price before we start and before-and-after photos of your own ducts. Air Duct Cleaning in Moraga has the full breakdown.
Dryer Vent Cleaning in Moraga
Lint accumulation in dryer vents is a fire hazard, and Moraga’s older homes often have longer vent runs through walls or crawl spaces that are harder to access. We use rotary brushes and high-velocity air tools to clear the full run from dryer to termination, checking for proper airflow at the exterior hood. If we find a crushed or improperly sloped vent, we’ll flag it and explain your options. Dryer Vent Cleaning in Moraga covers what to expect.
Duct Sealing in Moraga
Leaky ducts waste energy and pull in unfiltered attic or crawl-space air. In Moraga, seismic settling has opened gaps at joints in many older rigid-metal systems. We seal accessible leaks with mastic and reinforced tape, and we can apply aerosolized duct sealant for complex multi-zone systems in newer hillside homes where manual sealing isn’t practical. The goal is measured airflow improvement, not guesswork. Duct Sealing in Moraga explains our process.
