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 Air Duct Cleaning Across San Jacinto
Air duct cleaning in San Jacinto typically runs $350 – $650 for a full residential system, and most jobs are scheduled within a week of your call. If your registers blow a gritty film onto furniture every Santa Ana season, or your home still runs both legacy evaporative cooler vents and modern HVAC, you’re dealing with a buildup pattern that standard cleaning often misses. We dispatch crews from our Inland Empire office to San Jacinto regularly, and we know the difference between a cosmetic vacuum job and one that actually removes what locals call “the valley grit.” Call (361) 326-5060 for a free estimate with a written price before any work starts.
Why Hollis Air Duct Cleaning Is San Jacinto’s Preferred Air Duct Cleaning Company
We’ve been serving the San Jacinto Valley since 2004 as part of the Garrison Partners family, and our Air Duct Cleaning team has handled enough 1980s tract homes and old farmhouses here to know the ductwork by type. San Jacinto homeowners don’t call us because we’re the cheapest. They call because they’ve already watched a low-quote crew run a vacuum hose for forty minutes, hand them an invoice, and leave the grit blowing.
Our technicians are background-checked, uniformed, and held to The Garrison Code: arrive inside the window, price in writing, finish by the book, leave the site clean. Every job carries the 365-Day Done Right Promise in writing. If the work fails within a year, we return and make it right at no charge, including a free second visit. Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No callback queues.
We know the neighborhoods. We know the original galvanized trunks in the stucco builds off State Street, the sagging flex runs in the east-side agricultural parcels, and the dual-system headaches where evaporative cooler vents tie into modern HVAC. That local knowledge means we catch what out-of-town crews walk past.
Ductwork Cleaning in San Jacinto
Ductwork Cleaning in San Jacinto is not a one-size-fits-all job, because the ductwork itself isn’t one-size-fits-all. A typical full residential system clean runs $350 – $550, while larger homes or commercial setups can reach $650 – $950 depending on access and contamination level. The work starts with a camera inspection, not a vacuum hose. We need to see what we’re dealing with: original galvanized steel from a 1985 stucco tract, crushed flex above the air handler, or the mineral scale inside legacy cooler ducts that traps Santa Ana silica and cotton gin debris like glue.
Our crews use Rotobrush rotary brush systems for mechanical agitation and Nikro negative-air machines to maintain suction at the collection point. The rotary brush scrubs the duct walls while negative pressure pulls the dislodged material into a HEPA-filtered containment unit. We don’t blow debris toward your living space. We don’t skip the return side. And we don’t call it done until the post-clean camera pass shows smooth metal or intact flex, not a fresh coat of valley grit hiding in the corners.
What the Rotary Brush Actually Does
The Rotobrush is a powered cable with a bristle head that snakes through each supply and return run, knocking loose the packed dust and scale that a vacuum hose alone can’t touch. In San Jacinto’s hard-water-scaled cooler ducts, that mechanical action is what breaks the mineral layer free so the negative-air unit can capture it. Without agitation, you’re paying for a vacuum show.
Why Negative-Air Method Matters Here
The Nikro negative-air machine hooks to your trunk line and pulls a steady suction throughout the system while we work. This prevents the debris we disturb from escaping into your rooms. In older San Jacinto homes with gaps or disconnected runs, that containment is critical. Otherwise you’re just redistributing the valley grit through the house.
Air Duct Inspection in San Jacinto
Air Duct Inspection in San Jacinto is where most jobs should start, and where too many competitors skip straight past. A full video inspection runs $150 – $250 as a standalone service, though we credit that toward your cleaning if you proceed. We feed a lighted camera through your supply and return trunks, recording what we find: disconnected flex, crushed sections, scale buildup, or gaps pulling unfiltered attic air. You see the footage. We explain what it means for your airflow and your particle load. Then we write the price for any needed cleaning, sealing, or reconnection before touching a tool.
San Jacinto’s housing stock makes this step non-negotiable. The 1980s-1990s stucco tracts often have galvanized trunks that have sagged or separated at the joints. Older farmhouses may have single-wall construction with duct runs through unconditioned spaces that have never been sealed. And anywhere you find legacy evaporative cooler vents tied into modern HVAC, you’ve got junction points that corrode, leak, and collect debris in ways a camera reveals immediately.
What the Camera Catches That Eyes Can’t
A register might blow strong and feel clean to your hand while three feet upstream a flex run has pulled completely off the trunk, dumping attic air and fiberglass into the stream. We’ve found crushed sections above air handlers that reduced airflow by half without the homeowner knowing. The camera doesn’t guess. It shows.
When to Schedule an Inspection
Call for an inspection if you’ve never had your ducts opened, if you’ve recently bought an older home in San Jacinto, if you notice uneven heating or cooling room-to-room, or if a previous cleaning didn’t solve the grit problem. The inspection pays for itself in avoided repeat work.
Trusted Brands We Service in San Jacinto
We stock and install filtration and cleaning components from Honeywell, Aprilaire, and Abatement Technologies, the same brands commercial crews specify for hospitals and clean-room environments. For San Jacinto homeowners, that means no waiting on special orders when your system needs a media filter upgrade or a sealed return box. Our trucks carry the common sizes and fittings for Honeywell whole-house media cabinets and Aprilaire humidifier and filtration add-ons. If your system runs a Guardsman UV component or an Abatement Technologies HEPA bypass unit, we service those too. We don’t sell you a brand you don’t need. We match the component to the actual condition of your ductwork and your particle load.
Common Air Duct Cleaning Problems We See in San Jacinto Homes
- The valley grit layer in cooler ducts. San Jacinto’s hard water leaves calcium and magnesium scale inside legacy evaporative cooler ducts. That rough surface grabs Santa Ana wind silica and cotton gin debris in a bond that standard vacuuming won’t break. We find this on the east side near old agricultural parcels, and it takes rotary brush agitation plus negative-air extraction to actually remove it.
- Disconnected or crushed flex runs in 1980s-1990s tracts. The original flex duct in stucco builds off State Street and around the north side has often sagged, torn, or pulled off collars. The system still blows, but it’s pulling attic air through the gap and never filtering it. A vacuum-only crew misses this entirely. Our camera catches it every time.
- Unsealed junctions between cooler vents and HVAC trunks. Many San Jacinto homes run dual systems or have abandoned cooler vents tied into modern ductwork. Those junctions corrode and leak, becoming debris collection points and bypass paths for unfiltered air. Cleaning without sealing them just lets the grit re-enter.
- Blower motor and air handler pulling through gaps. Even clean ducts won’t help if the air handler cabinet or plenum has gaps pulling crawlspace or attic air. We check the whole pressure boundary, not just the runs, because in San Jacinto’s older housing stock the envelope is often as leaky as the ducts.

FAQs About Air Duct Cleaning in San Jacinto
San Jacinto sits in the path of Santa Ana winds that carry fine silica dust off the San Jacinto Mountains, plus agricultural debris from the valley’s cotton and citrus history. Many homes also have legacy evaporative cooler ducts with hard-water scale that traps that debris far more aggressively than smooth modern ductwork. The combination creates what locals call “the valley grit,” a packed layer standard vacuuming won’t touch. Call (361) 326-5060 and we’ll show you on camera exactly what’s in your system.
Yes. Dual-system homes need inspection at the junction points where cooler vents tie into HVAC trunks, because those connections often leak, corrode, or become debris collection points. We price dual-system jobs starting at $550 – $750 depending on configuration, and we always inspect before quoting. The camera pass shows whether you’re dealing with a simple clean or a reconnection and sealing job.
Disconnected flex runs, crushed sections above the air handler, corrosion at galvanized joints, and gaps pulling unfiltered attic or crawlspace air. In 1980s-1990s San Jacinto tracts, we find sagging original ductwork in about half the homes we inspect. The camera also reveals hard-water scale inside cooler ducts that a visual register check would never show. The inspection costs $150 – $250 and is credited toward your cleaning.
Cleaning without sealing is often half a fix. If your camera inspection shows disconnected runs or gaps at the plenum, sealing and reconnection stops the debris source and the unfiltered air bypass. We price sealing separately after inspection, typically $200 – $450, and we only recommend it where the camera proves it’s needed. The 365-Day Done Right Promise covers both the cleaning and any sealing work we perform.
A handyman typically runs a shop vacuum from the register end, which stirs debris into your living space and misses the trunk line entirely. Our crews use Rotobrush mechanical agitation and Nikro negative-air containment, with HEPA filtration on the exhaust. We camera-inspect first, clean supply and return separately, and verify with a post-clean camera pass. We also check the blower motor and air handler for gaps that would recontaminate the system. The difference is equipment, training, and verification – not just effort. Call (361) 326-5060 for an exact quote; estimates are free.
