Styles & brands we work with
Air Duct Cleaning Services
Air Duct Cleaning Services cover the full interior of your forced-air system: supply ducts, return ducts, registers, and the main trunk lines that carry conditioned air through your San Jose home. Over time those surfaces collect pet dander, dust, pollen, and in older houses, a surprising amount of construction debris from past renovations. We clean the entire path using Rotobrush rotary brush systems to agitate debris from the duct walls, paired with Nikro negative-pressure extraction to pull the loosened material out of your living space. Most San Jose homes run between $380 and $680 for a complete cleaning. The exact figure depends on home size, the number of returns, and how long it’s been since your last service. Either way, that number goes on paper before we begin.
Supply and Return Duct Cleaning
Supply ducts push conditioned air into your rooms. Return ducts pull room air back to the furnace or air handler. Both need attention, but return ducts usually collect more debris because they’re the intake side. We clean both thoroughly with the same rotary brush and negative-pressure process, no shortcuts.
Register and Grille Detailing
Registers are the visible face of your duct system, and they trap a lot of the dust that would otherwise settle on furniture. We remove, clean, and reset every register and grille we touch. The Kingswell Way standard means we leave the place cleaner than we found it, every time.

HVAC Duct Cleaning
HVAC Duct Cleaning addresses the ducts tied to your heating, ventilation, and air conditioning system as a whole, including the plenum, the main trunk line, and the branch runs off it. In San Jose, where air conditioners work hard from June through October, the cooling season forces air through coils and ducts that may have sat dormant and collecting dust all winter. That’s why the first few hot days often come with a stale smell from the registers. We use Abatement Technologies HEPA filtration during the job so the particles we loosen don’t drift into your living room while we work. Most HVAC duct cleaning in San Jose runs $380 to $680 for a standard single-family home, with the written price locked in before we start.
Plenum and Trunk Line Cleaning
The plenum is the box where your furnace or air handler connects to the main trunk line, and it’s a common collection point for fine dust and debris. We clean it as part of every HVAC duct cleaning, never as an add-on. The trunk line running through your attic or crawl space gets the same full brush-and-extraction treatment.
Coil Box Airflow Checks
While we have the system open, we check the area around the coil box for visible dust buildup that can restrict airflow. A clogged coil forces your AC to run longer to hit the same temperature, which shows up on your summer utility bill. We’ll flag it, photograph it, and explain what we found in plain terms before recommending anything.
Vent Cleaning
Vent Cleaning focuses on the visible openings where air enters and leaves your rooms: the supply registers, the return grilles, and the runs of duct immediately behind them. For many San Jose homeowners, this is where the problem is most obvious, because dust rings and gray smudges collect right on the vent covers. We pull each vent, clean the cover, brush the accessible duct behind it, and use negative-pressure extraction to capture what we loosen. Vent cleaning as part of a whole-system service falls within the usual $380 – $680 range for San Jose homes. If you only want certain vents addressed, we’ll quote a smaller scope, but we’ll be honest about what a partial cleaning will and won’t accomplish.
Ceiling and Floor Vent Removal
Floor vents in San Jose homes take a beating from foot traffic, pet hair, and the fine silt that blows through open windows during dry months. Ceiling vents collect a steadier layer of household dust. We remove both types carefully, clean them on site, and reset them when the job is done.
Return Air Grille Service
Return grilles often sit behind one large filter, and the grille itself can go years without attention. We remove the grille, clean the louvers, and check the filter slot for proper fit. If your filter is past its useful life, we’ll tell you, and we carry Honeywell and Aprilaire replacement filters for homeowners who want better air quality between service visits.
Air Duct Repair
Air Duct Repair handles the physical problems in your ductwork: loose joints, separated sections, small holes from rodents or past work, and crushed runs in crawl spaces. A separated duct in a San Jose attic can dump conditioned air into unconditioned space, and you’ll feel the difference as a hot or cold room before you ever see the problem. We find these issues during a visual inspection of accessible ductwork and flag them with photos before any repair is proposed. Simple repairs like resealing joints or patching small holes are quoted separately from the cleaning and priced in writing before work begins. For larger repairs we’ll explain the scope and the number to expect, with no pressure to proceed.
Joint Sealing and Reconnection
A duct joint that has worked loose over years of heating and cooling cycles leaks air every time the fan runs. We reseal joints with appropriate mastic or tape rated for ductwork, not whatever was left in the garage. A properly sealed joint means the air you paid to condition reaches the room it was intended for.
Damaged Run Replacement
Flex duct in crawl spaces and attics can get crushed by stored belongings, damaged by pests, or degraded by San Jose’s summer attic heat. If a run is beyond sealing, we’ll quote a replacement in writing before starting. You’ll know the number, the material, and the timeline before we go near it.
Ductwork Cleaning
Ductwork Cleaning is the broader structural cleaning of the entire duct network, not just the first few feet behind each vent. That means the long horizontal runs through your attic or crawl space, the elbows, the wyes, and the transitions where duct size changes. In San Jose, homes built in the 1960s and 1970s often have hard metal ducts with decades of accumulated dust, while newer construction frequently uses flex duct that sags and traps debris in the low spots. Our Rotobrush rotary brush reaches deep into these runs, and the Nikro negative-pressure unit keeps the dust moving in one direction: out of your house. The full ductwork cleaning in San Jose typically falls between $380 and $680, depending on the number of runs and access difficulty.
Hard Pipe Duct Systems
Metal ductwork found in many older San Jose homes holds up well structurally but collects a fine layer of dust that adheres to the walls over decades. Rotary brush agitation is especially effective on hard pipe, because it mechanically scrubs the surface rather than just blowing air through. We see the before-and-after difference on every job, and we photograph it for you.
Flex Duct Systems
Flexible ductwork is common in newer homes and additions throughout Santa Clara County. It’s easier to damage and more prone to sagging, so we inspect each accessible run for kinks and compression while we clean. Where a run has failed, we’ll show you the photo and quote a repair separately, with no obligation.
Air Duct Inspection
Air Duct Inspection is a visual and diagnostic look at the inside of your ductwork, usually done with a camera or a bright scope through the register openings. You might want an inspection before buying a San Jose home, after a renovation that produced heavy dust, or if you’re just not sure whether a cleaning is actually needed. During an inspection we look for dust accumulation, debris, mold-like growth, pest activity, and damaged or disconnected runs. We document what we find with photos and explain it in plain English. A standalone inspection is quoted in writing before we arrive. If we find significant buildup and you choose to proceed with cleaning, the inspection cost is credited toward the full service on most San Jose homes.
Pre-Purchase Inspections
Buying a house in San Jose is already complicated without wondering what’s hiding in the ductwork. We inspect accessible ducts and provide photos so you can make an informed decision. If the seller’s disclosure doesn’t mention duct condition, our inspection report gives you concrete information to work with.
Post-Renovation Inspections
Remodeling projects generate fine dust that settles throughout the duct system, especially if your contractor didn’t seal off the ducts during demolition. We inspect after renovations and confirm whether the system needs a full cleaning. Some homeowners are surprised at how much drywall dust a kitchen remodel pushes into the return ducts.
Residential Air Duct Cleaning
Residential Air Duct Cleaning covers single-family homes, townhomes, and condominiums throughout San Jose and the surrounding South Bay cities. Homes with pets, kids, or anyone with allergies tend to need more frequent cleanings, because pet dander and pollen get pulled into the return ducts and recirculated through every room. We schedule residential jobs in a defined window, show up on time, and work clean with drop cloths and shoe covers as standard practice. Most San Jose homes run between $380 and $680 for a complete residential duct cleaning. The price depends on square footage, the number of returns, and access, and it’s on paper before we start.
Pet Hair and Allergen Removal
Homes with dogs or cats push a remarkable amount of hair and dander through the return ducts. We see it on almost every residential job in San Jose, usually concentrated in the return runs near living areas. Rotary brush cleaning pulls that material out instead of pushing it deeper, and the HEPA filtration on our Abatement Technologies units keeps it from re-entering the air you breathe during the service.
Whole-Home Filtration Advice
After your ducts are clean, the right filter keeps them that way longer. We carry Honeywell and Aprilaire filters and can recommend the correct size for your system without upselling anything. A quality filter rated for your furnace or air handler is one of the best ways to maintain the result between cleanings.
Commercial Air Duct Cleaning
Commercial Air Duct Cleaning serves offices, retail spaces, medical suites, and light industrial facilities in San Jose, Santa Clara, and Fremont. These systems often run longer hours than residential units and move far more air, which means more dust loading in the same time period. We schedule commercial work around your business hours, including evenings and weekends where access allows, and we coordinate with property managers who need documentation for tenant records. Commercial pricing depends on building square footage, rooftop unit count, and duct accessibility, so a written quote follows a site walkthrough. What doesn’t change is the Kingswell Guarantee: the price is fixed before work starts, and the 365-Day Done Right Promise applies to every commercial job we do.
Rooftop Unit Duct Systems
Many San Jose commercial buildings use rooftop HVAC units feeding duct systems through the ceiling plenum. Dust, insulation particles, and occasional pest debris move through these ducts every day. We clean the full run from the rooftop unit to the terminal diffusers, using the same Rotobrush and Nikro equipment we run on residential jobs, scaled to the building.
Tenant Improvement Coordination
When a commercial space changes hands or gets renovated, the ductwork rarely gets touched. We work with property managers and contractors during tenant improvements to inspect and clean ducts before the new tenant moves in. Clean ducts at move-in mean fewer indoor air quality complaints during the first year of occupancy.

AfterBrands We Service
We service systems from every major HVAC manufacturer, and our technicians know the specific quirks of Honeywell and Aprilaire filtration products. Honeywell media filters and electronic air cleaners integrate with many San Jose residential systems, and our team understands how to service the ductwork around them without disrupting the filter setup. Aprilaire whole-home air purifiers and filters are common in South Bay homes with allergy-sensitive households, and we can recommend the right Aprilaire filter for your system after your ducts are clean.
For commercial clients, Abatement Technologies HEPA filtration equipment is a name we know well, because we run it on our own jobs. Whether you have Honeywell, Aprilaire, or any other make in your home, we can help. The ductwork is our focus, and that’s true regardless of the badge on the equipment.
Signs You Need a Pro Right Now
- Dust keeps returning within days of cleaning. If you dust the furniture on Sunday and by Thursday there’s a fresh gray film, your ducts are likely circulating fine particles every time the fan runs. A professional cleaning removes the reservoir of dust in the duct system rather than just moving it around your living room.
- Rooms stay uneven in temperature. One bedroom is freezing while the hallway stays warm. That often points to a disconnected or crushed duct, not a thermostat problem. We find these during the cleaning and document them with photos before proposing any repair.
- You can hear the system working but barely feel airflow. Restricted airflow can come from a clogged filter, a collapsed flex duct, or years of buildup narrowing the duct interior. None of these fix themselves, and running the system in this state wastes energy and shortens equipment life.
- Mold or mildew smell comes from the vents when the AC starts. San Jose’s dry summers are kind to ducts, but winter rains can introduce moisture into crawl spaces and attics. If your vents smell musty, schedule an inspection. We’ll identify whether the issue is in the ducts or at the coil, and we’ll tell you what we find straight.
- You recently completed a renovation or major construction. Drywall dust, sawdust, and insulation particles get pulled into return ducts during any significant remodel. If your contractor didn’t seal the ducts, that dust is now in your system and will circulate for months unless it’s cleaned out properly.
Our Process, Step by Step
- 1
Written quote before anything else. We walk the home, count the returns, assess access to the attic or crawl space, and put a fixed price in writing. That number doesn’t change when the van door opens. This is the Kingswell Guarantee, and it’s been the standard since 2004.
- 2
System setup and protection. We lay drop cloths from the entry to the work areas, wear shoe covers, and cover furniture near registers where needed. The negative-pressure unit seals to the duct system so debris is pulled out, not scattered around your home.
- 3
Rotary brush agitation of every reachable duct run. The Rotobrush system scrubs the interior walls of the ducts, dislodging dust, hair, and debris that air alone can’t move. We work run by run, covering supply, return, and trunk lines.
- 4
Nikro negative-air extraction. The Nikro unit draws loosened debris through a sealed hose into its collection system. Abatement Technologies HEPA filtration on the exhaust side ensures particles stay trapped and don’t re-enter the living space during the cleaning.
- 5
Final camera check and walkthrough. Before we pack up, we do a visual inspection of the cleaned ducts and review what we found. You get before-and-after documentation, and if anything looks short of the standard, we address it right there under the 365-Day Done Right Promise.
How Much Does Air Duct Cleaning Cost in San Jose?
A typical whole-home air duct cleaning in San Jose runs $380 to $680 for most single-family residences. Smaller condos and townhomes can fall below that range, while larger homes or systems with difficult attic access can run higher. Commercial pricing starts with a site walkthrough because building configuration drives the price more than square footage alone.
What affects the number: the number of returns, how long it’s been since the last cleaning, whether the ducts are hard pipe or flex, and how easily we can access the attic or crawl space. Homes with multiple stories or split systems cost more because there are more runs to clean. You avoid overpaying by getting a fixed, written price before work starts and by knowing exactly what’s included. A free estimate should tell you the total, the scope, and what’s not covered. Our estimates include all three, and the number is the number. No per-vent add-ons, no pressure to approve extra work during the job. Call (669) 220-7869 for a quote specific to your home.

Frequently Asked Questions About Air Duct Cleaning in San Jose
Air duct cleaning is the process of removing accumulated dust, pet dander, pollen, and debris from the interior of your forced-air system using rotary brush agitation and negative-pressure extraction.
