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.

AfterFast, Reliable Air Duct Cleaning Across San Bernardino
Air duct cleaning in San Bernardino typically runs $350 – $650 for a full residential system, and most jobs are scheduled within a few days of your call. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and our crews work out of the Inland Empire office to serve San Bernardino homes directly. If your registers blow dust when the AC kicks on, or you’ve noticed a musty smell cycling through the house, it’s worth having us look.
San Bernardino sits at the base of the San Gabriel Mountains, and that geography matters for your ducts. The Santa Ana winds funnel desert dust and smog straight into the valley, where it settles overnight into a thick, dark film inside ductwork. Homes in Del Rosa, the University District, and the older core near Base Line were built with galvanized steel ducts that were never designed for today’s filtration loads. We’ve cleaned systems in this city since 2004, and we know the difference between actual mold and the sooty residue that confuses a lot of homeowners here. Call (361) 326-5060 to get a written price before any work starts.

Every Hollis technician is background-checked, uniformed, and expected to work by The Garrison Code: arrive inside the quoted window, price in writing, complete the job by the book, leave the site clean. Our 365-Day Done Right Promise covers every job in writing. If the work fails within a year, we come back and make it right at no charge, including a free second visit. No negotiation, no runaround.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday for someone in another state to route your request.
Dispatch and scheduling for San Bernardino are coordinated from our Inland Empire office, so crews are already local when you call. We know the difference between a 1950s Del Rosa tract home with original galvanized ducts and a newer build on the north edge with flexible duct runs. That local knowledge changes how we approach the job.
Air Duct Cleaning Services in San Bernardino
Air Duct Cleaning Services in San Bernardino involve source removal of dust, debris, and particulate buildup from your entire duct network, using professional-grade rotary brush systems and negative-air machines. A typical residential full-system cleaning in San Bernardino runs $350 – $650, depending on system size, accessibility, and whether the home has original galvanized ductwork or modern flexible runs. Most San Bernardino homeowners schedule this every 3 – 5 years, though homes near the 215 freeway or in the path of seasonal Santa Ana winds may need attention sooner.
Residential Duct Cleaning
We clean supply ducts, return ducts, and the main trunk lines that connect them. In San Bernardino’s older neighborhoods, we often find supply registers clogged with fine desert dust that has compacted over decades. Our Air Duct Cleaning team uses Rotobrush rotary brush systems to agitate debris loose, then extracts it under negative pressure with HEPA filtration so nothing recirculates into your home.
Commercial Duct Cleaning
San Bernardino’s commercial buildings, from small offices near Hospitality Lane to retail spaces along Highland Avenue, accumulate dust at higher volumes due to foot traffic and extended HVAC runtime. We scale our equipment to the building size and schedule around your hours to minimize disruption.

HVAC Duct Cleaning in San Bernardino
HVAC Duct Cleaning in San Bernardino targets the complete forced-air system: ducts, registers, grilles, air handler, and blower assembly. A full HVAC duct cleaning in this market typically costs $450 – $750 for residential systems, with commercial jobs quoted individually based on square footage and system complexity. San Bernardino’s semi-arid climate means extended AC use from May through October, which keeps blower motors and evaporator coils under constant load. When ducts are dirty, the blower works harder, amp draw climbs, and your utility bill follows.
Video Inspection
We feed a camera through your ductwork before and after cleaning. In San Bernardino homes with 1950s galvanized systems, this often reveals loose joints, corrosion spots, or disconnected runs that explain why dust keeps returning. You see what we see. No guesswork.
Duct Sealing
After cleaning, we seal accessible joints with mastic. In older San Bernardino homes, this step matters more than the cleaning itself. Unsealed leaks let Santa Ana wind-driven dust re-enter the system within weeks, undoing the work you just paid for.
Trusted Brands We Service in San Bernardino
Our equipment roster includes Rotobrush rotary brush systems, Nikro negative-air machines, and filtration products from Honeywell, Aprilaire, and Guardsman. We stock parts and filters for these brands locally, so San Bernardino customers aren’t waiting on shipping from a warehouse three states away. If your system uses an Aprilaire media air cleaner or a Honeywell electronic air cleaner, we can service the housing and recommend the correct replacement filter during the same visit. For homes with Guardsman UV systems, we inspect lamp condition and airflow alignment. The point is to solve the whole problem in one trip, not hand you a list of follow-up appointments.
Common Air Duct Cleaning Problems We See in San Bernardino Homes
- Black, sooty residue mistaken for mold. In Del Rosa and the University District, we regularly open original 1950s galvanized ducts to find a 2 – 3mm black film that homeowners assume is microbial growth. Camera inspection usually shows it’s decades of smog and desert dust particulate, not mold. A fogging sanitizer won’t remove it. Source removal with rotary brush agitation and negative-air extraction will.
- Loose joints and corrosion in galvanized trunk lines. Post-war tract homes in central and western San Bernardino were built with steel ducts that have now seen 70+ years of thermal expansion and contraction. Joints loosen, seams crack, and corrosion forms at low points. Cleaning without sealing these leaks is temporary at best.
- Dryer vent buildup in homes with long vent runs. Many San Bernardino bungalows and ranch homes have dryer vents that run 20+ feet through walls or crawl spaces to reach an exterior wall. The lint trap looks clear, but the hidden run is where the fire risk builds. We clean the full pathway, not just the accessible section.
- Recontamination from Santa Ana wind events. After a strong Santa Ana wind period, we see spikes in calls from San Bernardino homeowners whose systems pulled dust through compromised return air pathways. If your filters are clean but dust returns quickly, the problem is likely duct leakage, not filter failure.

FAQs About Air Duct Cleaning in San Bernardino
It’s almost certainly soot and smog residue, not mold. San Bernardino’s position at the base of the San Gabriel Mountains traps desert dust and overnight smog settling into a thick, dark film inside ducts. In neighborhoods like Del Rosa and the University District, we’ve opened 1950s galvanized systems where homeowners were certain they had mold, only to find 2 – 3mm of compacted particulate that tested negative for microbial growth. A fogging sanitizer won’t remove this film. NADCA-standard source removal with rotary brush agitation and negative-air extraction will. Call (361) 326-5060 and we’ll camera-inspect it at no charge.
Yes, but for different reasons than humidity-driven mold. San Bernardino’s semi-arid climate and Santa Ana wind exposure create a dust-and-smog load that coastal cities don’t match. Where coastal ducts face microbial growth from moisture, San Bernardino ducts face abrasive particulate that accelerates blower motor wear and reduces airflow at registers. Extended AC use from May through October keeps the system circulating that debris constantly. Cleaning intervals here should be shorter than in milder climates. We can assess your system and recommend a schedule based on your neighborhood and home age.
Camera inspection is the only way to know for certain. We look for corrosion penetration, disconnected seams, and structural collapse. Surface rust and loose debris respond well to cleaning and sealing. But if the metal has rotted through or the trunk line has separated from the plenum, replacement is the honest recommendation. We’ve saved San Bernardino homeowners thousands by cleaning and sealing systems they assumed needed full replacement, and we’ve recommended replacement when cleaning would be throwing good money at failed metal. The inspection costs $85 – $150 and gives you a straight answer.
No. In San Bernardino’s specific environment, the black residue in older ducts is particulate matter, not microbial growth. Fogging a sanitizer over that debris does not remove the source. It masks odor temporarily, leaves a chemical film, and in some cases can degrade remaining mastic or corrode galvanized metal further. We don’t sell fogging sanitizers as an add-on because they’re not a substitute for source removal. If we find actual mold during inspection, we refer to a remediation specialist. For the soot-and-dust film typical here, mechanical agitation and extraction is what works.
A real cleaning includes: video inspection before and after; rotary brush agitation of all supply and return ducts; negative-air extraction with HEPA filtration; blower assembly and air handler cleaning; register and grille removal and cleaning; and accessible joint sealing with mastic. For 1950s galvanized systems, we pay special attention to loose joints near the air handler and corrosion at low points where condensate has collected.
