Call us at (844) 685-6342 for a free estimate with upfront pricing.
San Jose homeowners know their city isn’t like the rest of the Bay Area. The Santa Clara Valley’s bowl geography traps wildfire smoke, pollen, and Diablo Range soil with nowhere to go. That particulate doesn’t stay outside. It gets pulled into HVAC systems, settles in ductwork, and bakes in attics that hit 145°F through the summer months. We’ve cleaned ducts in Willow Glen, Almaden Valley, and the post-war tracts of East San Jose long enough to know what that buildup looks like, and what it takes to actually remove it.
Our technicians are background-checked, uniformed, and carry camera inspection equipment on every truck. We answer calls with a live person, 24 hours a day. Most San Jose appointments are scheduled within 48 hours, and we show up when we say we will.
Why Bellows Air Duct & Vent Co. Is San Jose’s Preferred Air Duct Cleaning Company
We’ve built our reputation in San Jose on one principle: the job is done right, or we come back and make it right. No paperwork, no arguing. Our 90-Day Done Right Promise is stamped on every invoice, and we’ve honored it since 1984.
San Jose customers call us after they’ve tried the coupon services. They tell us about technicians who spent 45 minutes in the house and left ducts that looked the same on the inside. We do the opposite. Every Air Duct Cleaning job starts and ends with a camera inspection. You see the debris before we start, and you see the clean ductwork after we finish. That’s not a marketing line. It’s how we’ve operated for four decades.
Our response time to San Jose is typically next-day or within 48 hours. We know the difference between the tight crawl spaces in Japantown bungalows and the sprawling attic systems in Almaden Valley ranch homes. That local knowledge means we bring the right equipment the first time, not after a scouting trip.
Ray Castillo, who leads Bellows, set the standard early: no bait pricing, no scare tactics, no price changes at the door. The number we quote on the phone is the number on the invoice. San Jose homeowners who’ve lived through Silicon Valley’s boom-and-bust contractor cycles appreciate that steadiness.
Our Air Duct Cleaning Services in San Jose
Residential Duct Cleaning
Most of our San Jose work is in homes, not offices. The 1950s-1970s tract homes that dominate ZIP codes 95118, 95119, 95120, and 95121 were built during the valley’s post-orchard suburban boom, and many still run original sheet-metal or early flex ductwork through unconditioned attics. That ductwork has never been cleaned. Our residential service pulls debris from every branch, not just the main trunk. We use Rotobrush agitation systems and HEPA-sealed vacuums to capture fine particulate that standard shop vacs recirculate back into your air.
Commercial Duct Cleaning
San Jose’s commercial buildings face a different load. The construction dust from continuous development in downtown and North San Jose settles in rooftop units and commercial duct systems that run longer hours than residential. We clean office parks near the airport, retail spaces on Stevens Creek Boulevard, and medical offices throughout the valley. Our commercial crews work after hours to avoid disrupting your business, and every job includes the same camera verification we provide homeowners.
Supply Duct Cleaning
Supply ducts push conditioned air into your rooms. In San Jose, they’re also the delivery system for whatever’s accumulated in your attic over decades. The Diablo wind events that stir soil and ash from the eastern hills deposit that material directly into attic-mounted systems. Cleaning supply ducts without addressing the source is half a job. We inspect each register and branch line, seal accessible leaks, and verify airflow improvement before we leave.
Return Duct Cleaning
Return ducts pull air back to your HVAC unit, and they’re often the dirtiest part of the system. In older San Jose homes, return pathways were sometimes improvised during furnace conversions, creating sharp turns and sagging sections that trap debris. Our camera inspection finds those traps. We clean returns with negative-air machines that maintain suction throughout the entire system, not just at the unit.
Full System Cleaning
This is our most complete service, and it’s what most San Jose homes need. Full system cleaning covers supply ducts, return ducts, the main trunk, registers, grilles, and the HVAC cabinet itself. For homes affected by wildfire seasons, including the 2020 SCU Lightning Complex fires that burned the hills surrounding San Jose, this is the only service that removes the compacted ash and soil residue that standard filter changes leave behind. We recommend full system cleaning every 3-5 years for San Jose homes, more frequently if you’ve experienced nearby wildfire exposure.
Video Inspection
We don’t guess. Our video inspection service sends a lighted camera through your entire duct network, recording what we find. For San Jose’s older housing stock, this is essential. We’ve found collapsed flex ducts in East San Jose attics, disconnected retrofits in Japantown bungalows, and fire-season debris packed into corners that visual inspection from the register could never reach. You receive the footage. There’s no dispute about what was there or what we removed.

Trusted Brands We Service in San Jose
We clean and service ductwork connected to all major HVAC brands, and we carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies on every San Jose truck. These are the same brands serious HVAC contractors specify for remediation work, not the consumer-grade tools sold at hardware stores. For San Jose customers, that means we can complete most jobs in a single visit without waiting for parts or equipment to ship. If your system includes Aprilaire or Honeywell air cleaners or UV components, we service those during the same appointment. One call, one trip, one honest price shown before we start.
Common Air Duct Cleaning Problems We See in San Jose Homes
- Wildfire ash baked into duct walls. The SCU Lightning Complex and subsequent fire seasons deposited smoke particulate throughout San Jose’s east-side attics. Those attics exceed 140°F in summer, cooking the ash and Diablo Range soil into a reddish-brown film that standard filters never captured. Many East San Jose homes have never had post-wildfire duct cleaning.
- Retrofitted ductwork in pre-WWII bungalows. Neighborhoods near Japantown and Naglee Park contain homes where ductwork was added during later furnace conversions. The mismatched connections create debris traps and airflow restrictions that are invisible from the registers. Without video inspection, these problems are routinely missed.
- Sagging or collapsed flex ducts in post-war tracts. Original flex ductwork from the 1960s and 1970s degrades in San Jose’s hot attics. We’ve found sections collapsed flat, completely blocking airflow to entire rooms. Homeowners blame their HVAC unit when the real problem is a duct that hasn’t carried air in years.
- Construction dust from continuous development. San Jose’s building boom doesn’t pause. Dust from nearby construction sites enters older homes with less effective envelope sealing, loading duct systems with particulate that the May-through-October dry season never washes out. The valley’s bowl geometry concentrates this load more severely than coastal Bay Area cities.
Pricing for Air Duct Cleaning in San Jose, CA
We’re transparent about pricing because we’ve seen what the alternative does to homeowners. Here’s what air duct cleaning costs in San Jose:
| Service | Typical Range in San Jose |
|---|---|
| Residential duct cleaning (single system, up to 10 vents) | $350-$550 |
| Full system cleaning with video inspection | $550-$750 |
| Commercial duct cleaning (per square foot) | $0.25-$0.45 |
| Dryer vent cleaning (added to duct service) | $89-$150 |
| Duct repair or sealing (per hour, if needed) | $150-$225 |
What moves the price? The number of vents and returns, accessibility of your attic or crawl space, whether we find damage requiring repair, and the level of contamination. A 1960s East San Jose tract home with original flex ducts and wildfire ash compaction takes longer than a 1990s Almaden Valley home with well-maintained metal ductwork. We assess this during your free estimate, and we show you the camera footage so you understand exactly what you’re paying for.
We offer a permanent 5% Senior and Veteran discount, $50 off any repair over $250, and a free second opinion on any written estimate you’ve received. Our $89 Seasonal Tune-Up is available if you want your HVAC system checked at the same time.

FAQs - Air Duct Cleaning in San Jose
San Jose’s bowl geography traps Diablo Range soil and wildfire ash, which then bakes in attics exceeding 140°F into a compacted reddish-brown film. Coastal cities like Santa Cruz or Half Moon Bay have prevailing onshore winds that flush particulates out, and their cooler, more humid attics don’t cook debris into the same hardened layer. Our crew recently cleaned a 1965 tract home in East San Jose’s 95111 ZIP, where original flex ducts in the 145°F attic had accumulated exactly this crust for three years. We used a Rotobrush system and HEPA vacuum to remove the compacted layer, then recommended a duct-sealing retrofit to prevent future infiltration. Call (844) 685-6342 if you’re seeing dust that matches this description.
Yes, we consider it essential for this housing stock. Original flex ducts from the 1960s and 1970s sag, collapse, or disconnect in hot attics, and these failures are invisible from the registers. We’ve found entire rooms receiving no airflow because a duct flattened decades ago. Video inspection records the actual condition of your ductwork before we clean, so there’s no dispute about what needs attention. For East San Jose homes that have never been inspected, this footage often reveals problems the homeowner didn’t know existed. Estimates are free, and we include the inspection footage with every full system cleaning.
The 2020 SCU Lightning Complex burned over 390,000 acres in the hills immediately surrounding San Jose, and the smoke particulate from that event is still present in ductwork that was never professionally cleaned. The material settled in attics, was drawn into HVAC systems, and then baked into duct walls through subsequent fire seasons. Standard disposable filters capture only a fraction of this load. We still receive calls from San Jose homeowners who smell smoke when they first run their heat each fall, three and four years after the fire. Full system cleaning with HEPA containment is the only way to remove this residue. If your home was in the smoke plume and you’ve never had post-fire duct cleaning, call (844) 685-6342 for an assessment.
Repair is usually possible and more cost-effective for pre-WWII homes near Japantown and Naglee Park, but the decision depends on what video inspection reveals. Retrofitted ductwork from furnace conversions often has mismatched connections and improvised routing that traps debris. We can seal accessible leaks, replace damaged sections, and improve airflow for significantly less than full replacement. However, if the ductwork is extensively damaged or improperly sized for your current HVAC unit, we will tell you directly that replacement is the better long-term value. Our free estimate includes camera footage and an honest recommendation either way.
San Jose homeowners turn on their heating systems in October and November after six months of disuse, and the first cycle often blows accumulated dust and wildfire residue into living spaces. The smell is immediate and unmistakable. Demand peaks in the first two weeks of October as temperatures drop and families notice the problem. We recommend scheduling cleaning in September, before the rush, to guarantee your preferred appointment time. Our 24/7 live answering means you can call (844) 685-6342 anytime to book ahead.
