We’re Bellows Air Duct & Vent Co., and we’ve been driving out to San Bernardino since 1984 to clean ductwork that other crews won’t touch - the tight attic crawls in 1950s Del Rosa tract homes, the converted gravity-furnace systems in Westside bungalows, and the smoke-embedded liners that standard filters can’t reach. Call (844) 685-6342 for a free estimate. We’ll answer.
Why Bellows Air Duct & Vent Co. Is San Bernardino’s Preferred Air Duct Cleaning Company
We’ve built our reputation in San Bernardino one job at a time, mostly through homeowners who tell their neighbors. Our Air Duct Cleaning team knows the difference between a 92407 split-level built in 1985 and a 92405 ranch house from 1962, and we clean accordingly. Most San Bernardino calls reach a live person in under 30 seconds, not a voicemail tree, and we schedule next-day or same-day service throughout the basin.
Our 90-Day Done Right Promise applies to every San Bernardino job in writing. If something’s not right, we come back. No paperwork, no arguing. Ray Castillo, who leads this company, set that standard in 1984 and hasn’t wavered.
Background-checked, uniformed technicians arrive with camera inspection gear from Rotobrush and Nikro systems. We show you the inside of your ducts before we touch them, and we show you after. That’s not a sales tactic. It’s how we prove the work.
Our Air Duct Cleaning Services in San Bernardino
Residential Duct Cleaning
San Bernardino’s housing stock tells a specific story. Post-WWII tract homes and ranch houses from the 1950s through 1970s dominate neighborhoods from Del Rosa to Westside, and many still run original sheet-metal or early fiberglass-lined ductwork that has never been professionally serviced. We clean these systems with equipment scaled to residential clearances, and we know how to navigate the tight attic spaces common in 1950s construction without damaging aging joists or compromised insulation. A typical residential duct cleaning in San Bernardino runs $280-$450 depending on system size and contamination level.

Commercial Duct Cleaning
Commercial properties along Hospitality Lane and in the downtown corridor face different pressures. Extended summer operation against 105°F heat loads commercial HVAC systems far harder than in cooler markets, and San Bernardino’s trapped airshed pushes more particulate through rooftop intakes. We clean commercial ductwork with Abatement Technologies HEPA-contained systems that keep your space operational during service. Most commercial jobs in San Bernardino range from $480-$1,200.

Supply Duct Cleaning
Supply ducts push conditioned air into your rooms, but in San Bernardino they also push whatever’s embedded in your duct liner. Wildfire smoke from the San Bernardino National Forest, Santa Ana wind dust from the Mojave, and decades of accumulated debris in unmaintained systems all travel this path. We clean supply lines with Rotobrush contact cleaning and negative-air HEPA containment, then verify with video. Supply duct cleaning as a standalone service in San Bernardino typically runs $180-$320.

Return Duct Cleaning
Return ducts draw air back to your handler, and in San Bernardino they draw the worst air in the nation. The American Lung Association has consistently ranked this airshed among the country’s most polluted for particle matter. Returns in older homes - especially gravity-furnace conversions with crawl-space flex runs - often contain rodent debris, soil particulates, and collapsed liners that standard filter changes never address. Return duct cleaning in San Bernardino generally costs $160-$280.

Full System Cleaning
Our most comprehensive service. We clean supply and return trunks, branch lines, registers, grilles, and the air handler cabinet. In San Bernardino, this is the service we recommend for any home that hasn’t had professional duct cleaning in five or more years, given the combined stress of particle pollution and extended AC run-times. Full system cleaning runs $380-$580 for most San Bernardino homes.

Video Inspection
Every Bellows job includes camera inspection before and after. In San Bernardino, this matters more than most places. Disconnected flex-duct joints inside post-WWII tract-home walls aren’t visible from registers. Collapsed crawl-space liners won’t show up in a standard visual check. We record what we find, show you the footage, and keep it on file. Video inspection as a standalone diagnostic runs $120-$180.

Common Air Duct Cleaning Problems We See in San Bernardino Homes
- Crawl-space flex-duct contamination in older Westside homes. In neighborhoods like 92411 and 92405, gravity-furnace conversions often run flex duct through vented crawl spaces inches above bare soil. These runs accumulate rodent debris, soil particulates, and collapsed inner liners that recontaminate the whole system within weeks if not properly cleaned and sealed.
- Disconnected joints hidden inside walls. Post-WWII tract-home ductwork in San Bernardino was often assembled with tape and mastic that degrades after decades. Crews who don’t camera-inspect miss these separations, leaving homeowners with cleaned ducts that still leak conditioned air into attics and walls.
- Filter changes sold as duct cleaning. Standard pleated filters catch particles down to about 3 microns. Wildfire smoke ultrafine particles and Santa Ana dust embed in duct liner at smaller sizes. A filter change won’t remove them. Only contact cleaning with professional extraction equipment will.
- Smoke-embedded liner from recurring wildfire events. The San Bernardino National Forest fires of recent years have pushed combustion particles through even well-sealed homes. These particles adhere to fiberglass duct liner and off-gas odor for months. We treat this with HEPA-contained agitation and, where needed, EPA-registered sanitizing agents.

FAQs - Air Duct Cleaning in San Bernardino
Most San Bernardino homes need professional duct cleaning every 2-3 years, not the 5-7 year interval recommended in cleaner-air markets. The combination of worst-in-nation particle pollution, 100°F+ summer run-times, and Santa Ana dust infiltration loads ducts faster here than in Redlands or Fontana. Homes with original 1950s-70s ductwork may need annual inspection. Call (844) 685-6342 for a free assessment of your specific system.
Professional cleaning removes most wildfire smoke odor by extracting embedded ultrafine combustion particles from duct liner, but severe cases may require supplemental sanitizing treatment. Standard filter changes and surface wiping won’t reach particles that have adhered to fiberglass surfaces. We verify results with post-cleaning camera inspection. If odor persists, we’ll discuss targeted treatment options when we quote.
Yes. These conversions are routine in Westside and north San Bernardino neighborhoods, particularly in ZIP codes 92411 and 92405. We clean the patched-in flex-duct runs, inspect crawl-space seals, and identify where soil infiltration and rodent debris have entered the system. We also flag disconnected joints and collapsed liners that conversion-era installers often left unaddressed.
92407 contains newer suburban tract development compared to the city’s older core, with generally better-maintained ductwork and fewer gravity-furnace conversions. However, homes here still face the same regional air quality challenges, and many were built during the 1980s-90s with flex-duct systems now reaching the end of their service life. We focus on liner degradation and seal failure in this area rather than the crawl-space contamination common in older neighborhoods.
Yes. Our camera equipment fits spaces as narrow as 6 inches, and our technicians are trained to navigate the cramped, blown-insulation-filled attics typical of Del Rosa and Highland-area construction from this era. We document everything we find. If a space is genuinely inaccessible, we’ll tell you upfront and discuss alternative access points rather than skip the inspection.
