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 Glendale, CA
Air duct cleaning in Glendale runs $350 – $650 for a typical single-system home, with most jobs scheduled within a few business days. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and we dispatch crews to Glendale from our Los Angeles office. Glendale homes aren’t like other Southern California markets: the wildfire corridors through the Verdugo Mountains and Angeles National Forest, the split housing stock from 1920s bungalows to hillside ranchers, and the ash re-entrainment problems after fire season all change how we approach the work. Call (361) 326-5060 for a free estimate.
Why Glendale Homes Are Different
Glendale sits directly in the path of Southern California’s worst wildfire smoke corridors. The Verdugo Mountains and Angeles National Forest burn regularly to the north and east, and the 2020 Bobcat Fire dumped ash across North Glendale and the 91201/91202 ZIP codes. Air duct cleaning here isn’t routine maintenance; it’s post-wildfire remediation. Homeowners in the foothills above Glenoaks call after every red-flag event because their ductwork pulls in ash, and the older housing stock means that ash is still sitting in unsealed 1950s-era duct runs.
The housing splits sharply by era. Pre-1940 bungalows and Spanish Revival homes in the 91201 – 91204 ZIPs near downtown and south Glendale often have original or half-century-old ductwork, sometimes retrofitted from floor furnaces, with leaky joints that trap debris. The hillside ranchers and 1960s – 70s tract homes in 91206/91208/91214 are more likely to have central HVAC but with aging flex duct that collapses and collects dust. After a major fire, we see a two-phase call pattern: first emergency cleanings from hill neighborhoods, then a second wave six months later when homeowners realize the ash smell never left because it re-entrained into the HVAC loop through the return plenum. Attic-mounted air handlers with loose flex duct connections make this worse.
Glendale’s Mediterranean climate means dry summers, but the fire-flood cycle dominates air quality. Santa Ana winds push smoke into Verdugo foothills neighborhoods like Glenoaks Canyon and Chevy Chase Canyon. Winter rains send fine ash-laden dust through HVAC intakes when homeowners restart systems after months of use.
Our Main Glendale Services
Glendale homeowners call us most often for these three services. Each has its own page with full pricing, process details, and neighborhood-specific notes.
Air Duct Cleaning in Glendale
We clean supply and return ductwork with Rotobrush rotary brush systems and Nikro negative-air machines, pulling debris out rather than pushing it deeper. In Glendale, we pay special attention to post-wildfire ash that cakes inside flex duct and metal trunk lines, especially in homes near the burn zones above Glenoaks Boulevard. We photograph the before condition and run a post-cleaning camera so you see the difference. Air Duct Cleaning in Glendale
Dryer Vent Cleaning in Glendale
Dryer vent cleaning in Glendale addresses lint buildup that restricts airflow and creates fire risk. Older Glendale homes, particularly the pre-war bungalows with extended vent runs through crawl spaces or walls, accumulate lint in ways newer tract homes don’t. We use rotary brushes and high-velocity air tools to clear the full run from appliance to termination, and we check for proper airflow before we leave. Dryer Vent Cleaning in Glendale
Duct Sealing in Glendale
Duct sealing with mastic and mechanical fasteners closes the leaks that let conditioned air escape into attics and crawl spaces. In Glendale, this matters most for the 1950s – 70s homes with deteriorating flex duct connections and the retrofitted systems in older bungalows where joints were never properly sealed. Sealed ducts also block ash re-entrainment during fire season, keeping contaminants out of the living space. Duct Sealing in Glendale
