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.
Fast, Reliable Air Duct Cleaning Across San Bernardino
Most San Bernardino homeowners pay between $320 and $580 for a complete residential air duct cleaning, and our crews typically schedule within three to five business days from your call. We dispatch from our Inland Empire office in the Riverside-San Bernardino corridor, so we’re not driving down from Los Angeles or up from Orange County - we’re already here, working the same roads you do.
We know the specific headaches San Bernardino properties present. The post-WWII tract homes near Mount Vernon Avenue with original sheet-metal ducts baking in 150°F attics. The apartment complexes along Baseline Street where shared dryer vent stacks haven’t been touched in a decade because nobody owns the full run. The north-facing homes that catch every Santa Ana event pouring through the Cajon Pass. Our Air Duct Cleaning team has cleaned ducts in your neighborhood, dealt with your parking constraints, and seen the reddish-tan Mojave silt that shows up here and nowhere else in the Inland Empire. Call (469) 972-3151 for a free written estimate.
Why Kestrel Air Duct Cleaning Is San Bernardino’s Preferred Air Duct Cleaning Company
We’ve been serving San Bernardino under the Kingswell Guarantee since 2004. That means a written price before any work begins, a defined arrival window, a clean job site, and a written guarantee with a free return visit if the work fails within the guarantee period. Four promises, every single time, no exceptions.
Our technicians are background-checked and uniformed, and they arrive with professional-grade equipment - Rotobrush rotary brush systems for dislodging debris at the duct wall, Nikro negative-pressure units for pulling contaminants out, and Abatement Technologies HEPA filtration to keep loosened particles out of your living space during cleaning. These aren’t box-store shop vacs with a long hose attached.
Calls are answered by a live person, 24 hours a day. Not a voicemail queue. Not an automated system that makes you press 3 for duct cleaning. A real conversation, any time you call.
We also know San Bernardino’s specific contaminant profile. The American Lung Association has given San Bernardino County failing grades for year-round particle pollution, and that pollution doesn’t stay outside. It enters your HVAC system through intake vents, through filter-bypassing gaps in aging ductwork, and through the thermal inversion that traps ozone and fine particulate matter close to ground level in this inland basin. We clean with that reality in mind.
Commercial Air Duct Cleaning in San Bernardino
Commercial Air Duct Cleaning in San Bernardino covers office buildings, retail spaces, warehouses along the I-10 and I-215 logistics corridor, and multi-unit residential properties with shared mechanical systems. The diesel particulate matter saturating local air in this hub of the Inland Empire’s warehouse district means commercial HVAC filters load faster and duct interiors accumulate a compounding mix of desert silt and combustion byproducts that standard maintenance intervals don’t address. Most commercial systems in San Bernardino run $680 to $1,400 for a full cleaning, depending on square footage, system complexity, and access.
Multi-Unit and Shared System Access
San Bernardino’s denser apartment and condo buildings present a specific challenge: crews arrive with full-size negative pressure units and find no legal parking or viable hose route. We solve this by surveying access during our free estimate visit, then deploying portable Nikro units sized to the building’s constraints rather than forcing oversized equipment into inadequate spaces. The Kingswell Way requires we say the price, show up in the window we gave, and leave the place cleaner - even when the job site is a cramped utility room off an alley.
Logistics Corridor Contaminant Loading
Warehouses and distribution centers near the BNSF rail yards and along the I-10 freight corridor face particulate loads that residential systems rarely match. Our commercial protocol adds pre-cleaning video inspection to document baseline conditions, then uses Rotobrush agitation followed by extended negative-air extraction cycles to remove the fine diesel soot that settles in duct trunks and return plenums.
Air Duct Cleaning Services in San Bernardino
Air Duct Cleaning Services in San Bernardino encompass residential duct cleaning, supply duct cleaning, return duct cleaning, full system cleaning, and video inspection for homeowners who want to see what their ducts actually contain before committing to service. A typical single-family home in San Bernardino runs $320 to $580 for complete supply and return cleaning, with video inspection adding $85 to $150 when requested. The work involves brush agitation to dislodge debris from duct walls, negative-air extraction to remove it, and HEPA filtration to prevent recontamination of your living space during the process.
Supply and Return Duct Specifics
Supply ducts push conditioned air into your rooms; return ducts pull air back to the HVAC unit for reconditioning. In San Bernardino’s older homes, we frequently find supply trunks with separated joints in attic runs where decades of 150°F summer heat have caused expansion and contraction. Return ducts often show heavier loading because they’re the intake point - pulling in that contaminated outdoor air through gaps around the filter rack. We clean both sides of the system and flag joint separations for sealing.

Full System Cleaning with Video Documentation
Our full system cleaning includes all supply and return ducts, the main trunk lines, and the plenum connections at the air handler. Video inspection lets you see the before condition - the gray lint, the reddish Mojave silt, the insulation fibers pulled through attic gaps - and the after. We provide the video file on request. The 365-Day Done Right Promise covers the full system: if airflow doesn’t improve or if visible debris remains, we return and make it right at no charge.

Trusted Brands We Service in San Bernardino
We clean duct systems connected to all major HVAC brands, and we stock filtration and indoor-air-quality products from Aprilaire, Honeywell, and Guardsman for San Bernardino homeowners who want to maintain clean air between service visits. Aprilaire media air cleaners upgrade from standard 1-inch filters to 4-inch pleated media that captures finer particles - a meaningful improvement in a market where outdoor air already carries heavy particulate loads. Guardsman UV air purifiers install in the ductwork to neutralize biological contaminants. We size these to your existing system and quote them in writing before any installation work begins.
Common Air Duct Cleaning Problems We See in San Bernardino Homes
- Cajon Pass desert silt infiltration. Santa Ana wind events drive high-velocity Mojave dust directly into north-facing homes, creating a distinctive reddish-tan powder layer beneath ordinary gray lint. Standard 1-inch fiberglass filters don’t stop it. We find this signature profile regularly in homes off Mount Vernon Avenue and in the Westside neighborhood.
- Attic heat separation in original sheet-metal ducts. San Bernardino’s post-WWII housing stock - single-story tract homes built from the 1940s through 1960s - has ductwork routed through unconditioned attics that exceed 150°F in summer. Joints separate. Gaps open. Unfiltered attic air and insulation fibers enter the supply stream. The system re-contaminates within months of cleaning if joints aren’t sealed.
- Shared dryer vent stacks in multi-unit buildings. No single tenant owns the full run, so lint accumulates past the reachable trap. This is the leading factor in home dryer fires, and it’s especially prevalent in San Bernardino’s older apartment stock along Baseline Street and in the downtown corridor where buildings haven’t had comprehensive vent service in decades.
- Filter bypass from poorly fitted racks. The fine particulate matter in San Bernardino’s outdoor air - compounded by diesel exhaust from the logistics corridor - accelerates interior buildup when filters don’t seat properly. We check filter fit during every cleaning and recommend media upgrades when the existing rack allows bypass.
Pricing for Air Duct Cleaning in San Bernardino, CA
A typical residential air duct cleaning in San Bernardino runs $320 to $580 for a complete supply and return system. Commercial systems range from $680 to $1,400 depending on square footage and access complexity. Video inspection adds $85 to $150. Dryer vent cleaning, when performed with duct cleaning, typically adds $120 to $180.
What moves you within these ranges? System size matters - a 2,000-square-foot home with one HVAC unit costs less than a 3,500-square-foot home with two zones. Access difficulty matters - crawl space ducts take longer than basement or attic runs. Contamination severity matters - the reddish Mojave silt and diesel particulate compounding in San Bernardino systems can require extended agitation and extraction cycles.
We give one flat price per system, agreed in writing before work starts. No per-vent pricing. No door-step revisions. The written price is in your hands before a single vent is touched. Estimates are free. Call (469) 972-3151.

FAQs About Air Duct Cleaning in San Bernardino
The Cajon Pass acts as a bellows during Santa Ana wind events, driving high-velocity Mojave Desert dust directly into north-facing HVAC systems at a loading rate neighboring cities don’t experience. On a post-WWII tract home off Mount Vernon Avenue north of downtown, our tech pulled a supply register and found a thin reddish-tan Mojave silt layer sitting on top of decades of gray lint - a signature profile for homes in the Cajon Pass dust path. Using Rotobrush agitation tools and a Nikro negative pressure setup with HEPA filtration, we cleaned the supply and return ducts, sealed separated joints in the attic run where summer heat had pulled gaps open, and restored airflow through the original sheet-metal trunks. Call (469) 972-3151 for an exact quote - estimates are free.
We survey access during our free estimate, then deploy portable Nikro negative-pressure units sized to the building’s constraints rather than forcing full-size equipment into inadequate spaces. For shared dryer vent stacks, we coordinate with property management to access the full run from multiple points, cleaning what individual tenants can’t reach. The written price covers the agreed scope before any work begins. Call (469) 972-3151 to schedule a building assessment.
Most San Bernardino homes benefit from cleaning every three to five years, but homes north of downtown in the Cajon Pass dust path or within a half-mile of the I-10/I-215 freight corridor should consider every two to three years due to the compounding load of desert silt and diesel particulate. The American Lung Association’s failing grades for San Bernardino County particle pollution reflect what your HVAC system processes daily. Call (469) 972-3151 and we’ll assess your specific location and system condition.
It matters significantly - shared dryer vent stacks in multi-unit buildings are the leading factor in home dryer fires because no single tenant owns the full run and lint accumulates past the reachable trap. We clean the complete stack from multiple access points with property management coordination. The service typically runs $120 to $180 when bundled with duct cleaning, or $180 to $280 as a standalone commercial stack cleaning. Call (469) 972-3151 for building-specific pricing.
We connect a Nikro negative-pressure vacuum to your system’s main trunk, insert Rotobrush rotary tools into each supply and return branch to dislodge debris from duct walls, and capture all loosened material through HEPA filtration so nothing re-enters your living space. We then inspect for joint separations, filter bypass, and other issues specific to San Bernardino’s climate and housing stock. The entire process takes three to five hours for a typical single-family home. You’ll receive a written 365-Day Done Right Promise before we leave. Call (469) 972-3151 to schedule.
