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 means removing the diesel soot, fine freight-corridor particulates, and decades of buildup that settle inside ductwork in this valley. A typical whole-home cleaning runs $425 – $780 depending on home size and system condition, and most jobs are completed in a half day. If you live near the I-10/I-215 convergence or the old Norton AFB logistics cluster, your ducts are working harder than almost anywhere else in Southern California. Call us at (980) 447-2498 and we’ll give you a written price before any work begins.
Why Linden Air Duct Cleaning Is San Bernardino’s Preferred Air Duct Cleaning Company
We’ve been serving homeowners since 2004 as part of the Threshold Group family, and the jobs we see in San Bernardino are different from what we find in neighboring cities. The air here is heavier with diesel exhaust and PM2.5, and the housing stock is older. That combination means we’re not just vacuuming out dust. We’re removing black, tacky soot from duct walls, finding collapsed flex runs in 1950s tracts, and sealing disconnected joints that have been dumping conditioned air into joist bays for years.
Every technician who arrives at your door in San Bernardino is background-checked, identity-verified, and wearing a clean, marked uniform. Before the visit, we send the tech’s name and photo. At the door, they show a photo ID badge. That’s the Threshold Standard, and it applies to every job we do. Marcus Veale leads our team with a straightforward rule: the price is in writing before work starts, and the 365-Day Done Right Promise means if the work isn’t right, we make it right. In writing. Every time.
Commercial Air Duct Cleaning in San Bernardino
Commercial Air Duct Cleaning in San Bernardino is a different job than residential work, and the warehouse-heavy economy here makes it essential. Office buildings, retail spaces, medical suites, and light industrial facilities along the Hospitality Lane corridor and near San Bernardino International Airport pull in the same diesel-heavy air as homes, but with longer run times and higher occupancy. A commercial system that moves air 10 to 14 hours a day traps particulates faster, and the buildup reduces airflow, shortens equipment life, and circulates freight-corridor soot through occupied spaces.
Commercial jobs in San Bernardino typically run $0.18 – $0.35 per square foot of conditioned space depending on system complexity, access, and the level of contamination. Restaurants and buildings near major truck routes often land at the higher end because grease and diesel soot combine into a residue that requires more aggressive agitation.
Office and Retail Systems
We clean rooftop units, main trunk lines, branch runs, and return plenums with negative-pressure extraction and Rotobrush agitation tools. The goal is source removal, not just a surface wipe. We also document everything with video inspection so building owners see exactly what was pulled and what condition the system is in after the job.
Medical and Light Industrial Facilities
For medical suites and light industrial spaces, we coordinate around operating hours to minimize disruption. We can provide before-and-after photo documentation and a written summary of what was removed. Marcus Veale’s team handles scheduling directly, so you’re never bounced through a call center.
Air Duct Cleaning Services in San Bernardino
Air Duct Cleaning Services in San Bernardino cover the full system: supply ducts, return ducts, air handler, and registers. We use negative-pressure extraction with HEPA filtration at the air handler, paired with Rotobrush agitation tools through every accessible run. This is source removal, not a register vacuum job. The equipment pulls the debris out of the duct and captures it, rather than blowing it around the house.
A full-system residential cleaning in San Bernardino runs $425 – $780 for homes up to about 2,500 square feet. Larger homes with multiple returns, older flex duct that needs video inspection, or heavy diesel-soot buildup can run higher, and we’ll tell you the exact number before we start. No per-vent pricing. No surprise invoice at the end.
Residential Full-System Cleaning
We clean supply and return runs, the plenum, the blower compartment, and register boots. If your home was built before 1970, we’ll run a video inspection as part of the job because disconnected wye joints are common in these tracts and cleaning alone won’t fix a bypass dumping air into the attic.
Video Inspection and Documentation
Every San Bernardino job can include a video inspection. We show you what’s inside the ducts before and after. If we find a collapsed run or a disconnected joint, we document it with photos and give you the repair price in writing. No pressure. Just the facts.

Trusted Brands We Service in San Bernardino
We run professional-grade equipment from Rotobrush and Nikro, and we stock air-quality products from Aprilaire and Guardsman. That matters in San Bernardino because the particulate load here is heavy enough that a basic fiberglass filter won’t keep a cleaned system clean. We recommend and install MERV 11 – 13 filters from Aprilaire for most homes in this air basin, and we carry Guardsman products for duct sealing and antimicrobial treatment in systems where moisture has been an issue. If your system needs a specific part, we can typically source it locally and have it on the truck for the first visit. That keeps turnaround fast, which matters when your ducts are recirculating diesel soot.
Common Air Duct Cleaning Problems We See in San Bernardino Homes
- Disconnected wye joints in post-WWII tract homes. Original flex duct from the 1950s through the 1970s was often secured with tape that dries out and fails. The run separates at the wye, and the system dumps conditioned air into the joist bay while pulling unfiltered attic air back in. Cleaning the accessible run won’t fix this. The joint needs to be reconnected and mastic-sealed.
- Black, tacky diesel soot on duct walls. Homes within a mile or two of the I-10/I-215 convergence and the logistics cluster near San Bernardino International Airport accumulate a residue that looks and feels different from normal household dust. It’s oily, dark, and requires agitation with professional tools to remove. A surface wipe won’t touch it.
- Collapsed original flex runs. Deferred maintenance after the 2012 municipal bankruptcy left a lot of San Bernardino systems untouched for decades. Original 6-inch flex runs sag, kink, and collapse, strangling airflow to back bedrooms. We find this constantly in homes off Del Rosa Avenue, Kendall Drive, and along the base of the San Bernardino Mountains.
- Santa Ana seasonal contamination spikes. Fall wind events push Mojave Desert dust and wildfire ash from the San Bernardino National Forest into return-air intakes. If the system has a low-MERV filter, that fine material coats the duct walls within weeks. Source removal plus a corrected filter rating is what actually stops re-contamination.
Pricing for Air Duct Cleaning in San Bernardino, CA
A typical residential full-system cleaning in San Bernardino runs $425 – $780 for homes up to about 2,500 square feet.

Video inspection is included on jobs where we suspect duct damage, and if we find a disconnected joint or collapsed run, the repair price is quoted separately in writing.

FAQs About Air Duct Cleaning in San Bernardino
That dark, oily residue is diesel exhaust particulate from the freight corridors along I-10 and I-215. San Bernardino sits in a thermal inversion bowl where the San Gabriel and San Bernardino mountains trap pollution in the valley. The American Lung Association grades San Bernardino County an ‘F’ for ozone and PM2.5. Homes near the logistics cluster around San Bernardino International Airport accumulate soot at a visibly different rate than homes in Riverside or Redlands. It’s not household dust. It requires professional agitation and HEPA-filtered negative-pressure extraction to remove. Call (980) 447-2498 and we’ll show you exactly what’s in your ducts before we start.
You can expect some combination of disconnected wye joints, collapsed original flex runs, and heavy soot buildup on the duct walls. We pulled a camera down a 1958 tract-home system off Del Rosa Avenue near the base of the San Bernardino Mountains and found the original 6-inch flex run to the back bedroom disconnected at a wye, dumping conditioned air into the joist bay. After reconnecting and mastic-sealing the joint, static pressure dropped enough that the blower motor stopped short-cycling. That’s a typical San Bernardino job. Call us for a video inspection and a written report of what we find.
No. Cleaning the accessible run removes buildup, but if a joint is disconnected at the wye, the system is still bypassing air into the joist bay and pulling unfiltered attic air back in. That’s why we run a video inspection on older San Bernardino homes. If we find a disconnect, we quote the repair separately and in writing. The 365-Day Done Right Promise covers our work, and any covered repair that fails gets a free second visit. Call (980) 447-2498 and we’ll inspect before we quote.
We recommend every 3 to 5 years for most San Bernardino homes. That’s more frequent than Riverside or Redlands because the freight corridor along I-10 and I-215 pushes diesel soot into this valley, and the thermal inversion keeps it there. Homes within a mile or two of the logistics cluster near San Bernardino International Airport or the warehouse district along Hospitality Lane should consider every 2 to 3 years. If you run a MERV 11 – 13 filter from Aprilaire and seal any disconnected joints, you can stretch toward the longer end. Call (980) 447-2498 and we’ll assess your specific system.
A MERV 11 – 13 filter is the right range for most San Bernardino homes. It captures the fine PM2.5 particulates without choking airflow on older blowers. A basic fiberglass filter won’t stop diesel soot from coating your duct walls, and the system re-contaminates within weeks of a cleaning. We stock Aprilaire filters and can install the correct size during your duct cleaning visit. Call (980) 447-2498 for a specific recommendation based on your system.
