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 HVAC Cleaning Across San Jose
HVAC cleaning in San Jose, CA typically costs between $380 and $720 for a full system cleaning of a single-family home, including air handler, evaporator coil, blower, and supply and return ductwork. Most jobs in San Jose take between 3 and 5 hours when done properly with negative-pressure extraction and mechanical agitation, not just a shop-vac on the register. If you’re in Cambrian, Berryessa, Alum Rock, or East San Jose and your registers haven’t been opened in five years or longer, call (806) 606-6902 for a written price before we touch a single panel.
We work on San Jose’s older ranch homes every week, so we know what’s behind those registers before we pull the first one off. The duct runs, the attic heat, the decades of dust, the disconnected collars at the plenum. It’s predictable once you’ve seen enough of it. That predictability is what lets us put a real price in writing before the truck arrives, no per-vent math, no tour of the attic that turns into a new invoice.
Why CleanRun Air Duct Cleaning Is San Jose’s Preferred HVAC Cleaning Company
Since 2013, CleanRun Air Duct Cleaning has built its San Jose reputation on one thing: documentation. Every job we’ve done here has included a photographed record of every duct run before and after the work. That’s 52,000+ homes served, each with a written price agreed before any work started and a photo record delivered when the crew left. In San Jose specifically, that documentation matters because the work happens in attics. You can’t watch it. The photos are how you verify it.
Our technicians are background-checked, uniformed, and working under H.A.V.E.N. Standard Clause 3: Verified Crews. When they arrive at your San Jose home, they introduce themselves by name and they don’t start until you’ve seen the written scope. The license number is published on the page, not buried in a footer. We don’t ask you to trust us; we hand you the record.
San Jose homeowners tend to ask sharper questions. They’ve quoted the job three ways. They want to know what equipment we run. We run Rotobrush and Nikro systems for source removal, HEPA-filtered negative air machines from Abatement Technologies, and we carry Honeywell and Guardsman products for coil treatment and filtration. You can look those up before we arrive. We expect you to.
And we answer the phone. A live person, not a call center, handles calls for San Jose service at (806) 606-6902.
Our HVAC Cleaning Services in San Jose
HVAC cleaning is not one service and it shouldn’t be sold as one. It’s four distinct surfaces inside the system, each with its own failure mode in San Jose homes. When you book a full HVAC Cleaning with us, we address all of them and document each one in writing and photos.
Air Handler Cleaning
The air handler is where San Jose’s wildfire smoke residue settles most heavily. The blower pulls smoke-laden air from the return side, and fine particulates coat the blower wheel, the housing, and the interior surfaces. In the 1960s and 1970s ranch homes around Berryessa and Cambrian, the air handler is often in a hallway closet or the garage, and the interior is caked with a gray-black film that reduces airflow and puts load on the motor. We disassemble what needs to be disassembled, clean the wheel and housing, and document the before and after.
Evaporator Coil Cleaning
The evaporator coil sits in the supply plenum, and in San Jose it’s nearly always dirty. The valley’s fine dust and smoke particulates pass through a standard filter and accumulate on the coil’s fins, especially where moisture condenses during cooling season. A fouled coil reduces heat exchange and forces the system to run longer cycles, which is money out the window in San Jose’s summer. We clean coils with professional-grade coil treatments and document the pressure drop before and after when applicable.
Blower Cleaning
A dirty blower wheel can carry enough imbalance to chew through bearings over time. In San Jose homes that went through the 2020 SCU Lightning Complex fires or the CZU fires, the blower is often the first place you’ll see visible smoke damage. We remove the wheel, clean it properly, and check the motor amp draw to make sure it hasn’t been laboring against grimed-up vanes. If the motor is pulling high amps, we show you the number in writing and explain what it means.
Condenser Cleaning
The outdoor condenser in a San Jose backyard picks up every kind of debris the valley produces: cottonwood seed, jasmine dust, construction dust from infill projects, ash, and the fine gray dust that accumulates on any flat surface in this valley. A clogged condenser coil is the most frequent cause of reduced cooling demand we see in San Jose from May through September. We clean the evaporator coil and the condenser coil as part of the full scope, and each gets its own photo record.

BeforeAfterTrusted Brands We Service in San Jose
We service and clean all major HVAC brands in San Jose homes, including Carrier, Trane, Lennox, Goodman, and Rheem. The equipment we use on your system matters equally: Rotobrush for the duct runs, Nikro for negative-air containment, and Guardsman coil treatments. We stock common filter sizes and coil products locally for San Jose customers, which means fewer return trips and faster completion on most jobs. If your San Jose system has an Aprilaire or Honeywell whole-home filtration unit, we can service that as part of the same visit.
Common HVAC Cleaning Problems We See in San Jose Homes
- Disconnected or collapsed flex duct from attic heat. San Jose’s low-slope ranch attics routinely hit 130-140°F in summer. That heat degrades flex duct insulation and causes the inner liner to sag, crack, or pull free at the collar joints. A cleaning job often turns up disconnected runs that have been dumping conditioned air into the attic for years. We reconnect and seal with mastic or UL-listed foil tape, never duct tape.
- Wildfire smoke residue baked into supply ducts. When smoke from the Santa Cruz Mountains or Diablo Range hangs over the valley, it enters the return side and gets driven through the system. Fine ash coats the inside of supply ducts and recurs through living spaces long after the air outside clears. Cleaning only the return side and ignoring the supply runs means that residue stays in your air.
- Decades of dust in never-cleaned ductwork. The dominant San Jose housing stock was built in the 1960s through the 1980s. Many of those systems have had nothing but filter changes for 40 years. The camera shows it in the first 30 seconds: a 3-inch debris build-up at the first elbow, a layer of construction dust from the original build, sometimes a toy or a sock from two owners ago.
- Partially closed or obstructed dampers. Older San Jose homes often have dampers that have been painted over, bent, or simply forgotten. A system can be cleaned perfectly and still have pressure imbalance because a damper on the supply plenum is half-closed. We check and document damper position as part of the job.
Pricing for HVAC Cleaning in San Jose, CA
We don’t do per-vent pricing. We quote one flat price per system in writing before we begin, under Haven Standard Clause 1, and that price covers everything: air handler, evaporator coil, blower wheel, condenser coil, and all supply and return duct runs. For a typical San Jose single-family home with one system, the written price ranges from $380 for a smaller single-story to $720 for a larger two-story or a system with long attic runs. What moves the number within that range is linear feet of accessible duct, number of returns, and whether we need to remove a blower wheel. You’ll see that number in writing before a single screw comes out. That’s the whole point of the brand.
We also offer a free second opinion on any written competitor estimate. Bring us a quote from another company and we’ll put our number next to it, in writing, for the same scope of work.

FAQs - HVAC Cleaning in San Jose
San Jose sits in a bowl-shaped valley ringed by fire-prone ranges, the Santa Cruz Mountains to the west and the Diablo Range to the east, and when those ranges burn, temperature inversions trap smoke at ground level and push it into residential ductwork at concentrations coastal cities don’t experience. San Francisco’s marine winds disperse particulates; San Jose’s geography concentrates them. It’s not unusual for our techs in San Jose to find a visible smoke film inside the blower housing and on the supply ducts months after a fire event, even in homes where the windows were kept closed.
No. Cleaning removes the debris inside the duct runs; it does not reconnect a flex run that has pulled free at the collar. That’s a repair, and it’s part of why our San Jose jobs start with a camera inspection of the entire run. If we find a disconnected or crushed section, we document it in photos, show you the picture, and include sealing and reconnection as a line item if you want it done. In many San Jose homes, the sealing is the actual fix and the cleaning is the prerequisite. We do both.
We use both. Negative pressure alone won’t remove the layer of impacted dust and smoke residue adhered to the inside of San Jose ductwork, especially in older runs that have had decades of buildup. We use mechanical agitation from Rotobrush systems in the duct runs while maintaining negative pressure with HEPA-filtered air machines, which pulls loosened debris out of the home for good rather than redistributing it. That’s what source removal means, and it’s the only method we use.
Wildfire smoke is fine enough to pass through a standard 1-inch filter, which means it coats the blower wheel, the inside of the air handler housing, and the evaporator coil. In San Jose, where wildfire smoke events are now a recurring feature of late summer and fall, that accumulation builds with each incident. A fouled blower wheel can throw off balance and increase motor amp draw, eventually shortening bearing life. We clean the wheel and housing as part of a full HVAC cleaning and check motor amp draw on the spot.
MERV stands for Minimum Efficiency Reporting Value, and it measures how effectively a filter captures particles between 0.3 and 10 microns. A MERV 8 filter is what most San Jose systems have, and it captures basic dust. A MERV 11 or MERV 13 captures much more of the fine smoke particulate that hangs around San Jose’s valley during fire season, which means less of it ends up inside your air handler and ductwork. The trade-off is static pressure; a dense filter on an underpowered older San Jose system can reduce airflow. We check your system’s static pressure before recommending a higher MERV rating, and we’ll tell you in plain English whether your 1960s ranch system can handle it.
