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 Alhambra, CA
Air duct cleaning in Alhambra typically costs $350 – $650 for a whole-home system and is scheduled by appointment with a written price confirmed before work begins. Hollis Air Duct Cleaning serves Alhambra from our Los Angeles coordination office, sending background-checked, uniformed crews equipped with Rotobrush rotary brush systems and Nikro negative-air machines to homes across the San Gabriel Valley. Alhambra’s post-WWII housing stock and location in the smog belt create specific duct conditions we address differently than newer suburban markets. Call us at (361) 326-5060 for a free estimate.
Why Alhambra Homes Are Different
Most Alhambra homes are single-story ranch houses built between 1945 and 1970, with original galvanized steel ductwork that frequently leaks at joints. The city also has many two- and three-story apartment buildings from the 1960s through the 1980s with centralized vertical duct chases that are difficult to access without the right equipment. In the older tract homes near Almansor Park, the original ductwork was often installed with minimal insulation and no return-air plenum, causing dust to recirculate and triggering allergy complaints from residents who’ve never had ducts cleaned since the home was built.
Alhambra’s Mediterranean climate brings hot, dry summers often exceeding 95°F and mild, damp winters, leading to year-round HVAC use and rapid dust buildup. The San Gabriel Valley’s smog and seasonal Santa Ana winds drive fine particulates into duct systems. Combined with heavy tree canopy throughout residential neighborhoods, ducts here accumulate a distinctive mix of pollen, smog particulates, and attic dust that requires HEPA-level extraction, not a basic vacuum attachment.
Many buildings along the Valley Boulevard corridor still run original ductwork undersized for modern HVAC loads, which means our crews regularly encounter systems working harder than designed, moving more debris, and wearing out faster than owners expect.
Our Main Alhambra Services
Alhambra homeowners most often call us for these three services, each handled with The Garrison Standard of written pricing, uniformed technicians, and our 365-Day Done Right Promise.
Air Duct Cleaning in Alhambra
We clean supply and return ducts, registers, and the main trunk line using a Rotobrush rotary brush system paired with negative-air extraction. In Alhambra’s 1950s ranch homes, we frequently find decades of compacted dust in galvanized steel lines that were never sealed properly at installation. Our crew photographs the interior before and after so you see what came out. Every job gets a written price before we start and is covered by our 365-Day Done Right Promise.

Dryer Vent Cleaning in Alhambra
Dryer vent cleaning removes lint buildup from the appliance through the exterior termination, reducing fire risk and drying time. Alhambra’s older apartment complexes with vertical runs through multiple floors require specialized Nikro equipment to clear long duct paths safely. We inspect the full run with a camera when access allows, and we note any damaged sections that need repair. Dryer Vent Cleaning in Alhambra
Duct Sealing in Alhambra
Duct sealing closes leaks at joints, seams, and connections using mastic sealant and metal-backed tape. In Alhambra’s original tract homes, we regularly find 20 – 30% air loss through gaps in galvanized steel connections that were never properly sealed in the 1950s or 1960s. Sealing these leaks improves airflow to rooms, reduces HVAC runtime, and keeps attic dust and insulation particles out of the air you breathe. Duct Sealing in Alhambra
