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.
Air Duct Cleaning Company in San Bernardino, CA
Air duct cleaning in San Bernardino typically runs $300 – $600 for a whole-home system, with most jobs completed in a single visit. San Bernardino’s unique position at the foot of the San Bernardino Mountains creates a dust-and-smog combination that coats ductwork more aggressively than in coastal California cities. Hollis Air Duct Cleaning dispatches crews from our Inland Empire office to handle these local conditions with Rotobrush rotary systems and Nikro negative-air machines. Call (361) 326-5060 for a written estimate before any work begins.
Why San Bernardino Homes Are Different
San Bernardino sits where high desert dust meets basin smog, and that mixture doesn’t stay outside. Overnight temperature inversions trap particulates against the valley floor, then your HVAC system pulls them through the intake. Over years, this creates a dark, stubborn film inside ductwork that standard vacuuming won’t touch.
The housing stock tells the same story. Much of central and western San Bernardino was built in the post-war boom with galvanized steel ducts that were never designed for modern filtration. In Del Rosa and the University District, we regularly open systems that haven’t been cleaned since the 1950s. Homeowners often call worried about “black mold” inside the vents; testing usually shows it’s accumulated smog residue and desert dust packed into a layer thick enough to restrict airflow. Newer developments on the city’s edges have flexible ductwork, but the Santa Ana winds still push extraordinary debris loads through outdoor units and any gap in the system.
Extended cooling seasons here mean systems run eight or nine months straight. That constant circulation accelerates buildup and means any leak in the ductwork is actively distributing particles through living spaces year-round.
Our Main San Bernardino Services
Most San Bernardino homeowners call us for one of three jobs. Each has its own page with full details on what we find in local homes and how we handle it.
Air Duct Cleaning in San Bernardino
We clean the full supply and return network with a Rotobrush rotary brush system that scrubs duct walls while a Nikro negative-air machine pulls loosened debris out of the house entirely. In San Bernardino’s older homes, we often find original steel ductwork with corrosion at the joints that traps debris; we document this before we start and adjust our approach so nothing gets pushed deeper. Every job gets a written price upfront and the 365-Day Done Right Promise. Air Duct Cleaning in San Bernardino

Dryer Vent Cleaning in San Bernardino
Dryer vents in San Bernardino clog faster than expected because desert dust mixes with lint into a dense, compacted mat. We run a rotary brush through the full vent line to the exterior cap, then verify airflow with a meter. In homes with roof terminations or long horizontal runs through crawl spaces, common in the city’s mid-century builds, we use a camera to confirm the line is clear.

Duct Sealing in San Bernardino
San Bernardino’s original galvanized steel ducts were joined with tape that degrades after decades of heat cycling. We seal leaks with mastic compound and mechanical fasteners, then pressure-test the system to verify results. This matters especially here: every gap pulls in attic dust and garage fumes, and with systems running most of the year, those leaks never get a break. Duct Sealing in San Bernardino
