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 Agoura Hills, CA
Agoura Hills homeowners typically pay $450 – $850 for whole-house air duct cleaning, with most jobs scheduled within a week and completed in a single visit. We’re Hollis Air Duct Cleaning, and we run our Agoura Hills jobs differently because this foothill city is different: chaparral dust, oak pollen, wildfire ash, and 1970s – 1990s ductwork that often hasn’t been touched since construction. Call us at (361) 326-5060 for a free written estimate before any work starts.
Why Agoura Hills Homes Are Different
Agoura Hills sits in the Santa Monica Mountains foothills where the indoor-outdoor lifestyle runs year-round. Windows stay open through long dry summers and mild winters, so ducts load up with fine mineral dust and oak and pine pollen blown in from surrounding chaparral and canyon corridors. Roughly half the city’s housing sits in the Wildland-Urban Interface, where ember-intrusion vent screening and defensible-space habits are part of everyday life. Duct cleaning here is as much about reducing wildfire-ash intrusion and maintaining vent hardware as it is about routine dust removal.
Most homes were built in the 1970s – 1990s, tract and hillside custom builds with original or lightly retrofitted flexible-duct runs in attics and crawlspaces paired with older sheet-metal plenums. High turnover ownership means we regularly encounter ducts that have never been professionally cleaned. After the first strong Santa Ana winds each fall, we see a spike in calls from canyon-edge neighborhoods like Old Agoura for ducts packed with fine grey ash and grit. Sustained down-canyon winds push wildfire debris and dry soil past standard vents, and standard coastal cleaning schedules don’t account for it.
The climate is hot-summer Mediterranean: very dry, warm summers and mild, mostly frost-free winters. Relative humidity stays too low to sustain the biological growth seen in coastal or humid climates, so Agoura Hills cleaning focuses on particulate removal and mechanical integrity rather than mold remediation.
Our Main Agoura Hills Services
These are the three services Agoura Hills homeowners call us about most. Each has its own page with full pricing, process details, and neighborhood-specific notes.
Air Duct Cleaning in Agoura Hills
We clean the full supply and return duct network using a Rotobrush rotary brush system or Nikro negative-air machine, depending on your duct material and layout. In Agoura Hills, we pay special attention to flexible-duct runs in older attics, which can sag or tear after decades of heat cycling, and we inspect vent screens for ember-intrusion compliance in Wildland-Urban Interface zones. Every job gets a written price before we start and is covered by our 365-Day Done Right Promise. Air Duct Cleaning in Agoura Hills
Dryer Vent Cleaning in Agoura Hills
Dryer vent cleaning in Agoura Hills addresses lint buildup in runs that often stretch through multiple walls or attic spaces in hillside homes. The dry climate means lint accumulates statically, and longer vent runs common in custom builds reduce airflow and extend drying times. We clear the full run from dryer to termination, inspect for proper backdraft and ember screening, and test airflow before we leave. Dryer Vent Cleaning in Agoura Hills
Duct Sealing in Agoura Hills
Duct sealing closes leaks in supply and return plenums, trunk lines, and branch runs using mastic and reinforced tape rated for your system’s temperature range. In Agoura Hills, we frequently seal leaks in original sheet-metal plenums and at flexible-duct connections that have loosened over decades of thermal expansion. Sealed ducts reduce the dust and pollen infiltration that open windows already exacerbate, and they cut the load on your HVAC system. Duct Sealing in Agoura Hills
