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.

Why Hollis Air Duct Cleaning Is Upland’s Preferred Air Duct Cleaning Company
We’ve been in business since 2004 as part of the Garrison Partners family, and our Upland customers come back because we show up inside the window, price the job in writing before touching anything, and leave the site clean. The Garrison Standard applies to every dispatch: background-checked, uniformed technicians; live phone answering 24 hours a day, 7 days a week; and the 365-Day Done Right Promise covering every job in writing. If the work fails within a year, we return and make it right at no charge, including a free second visit.
Upland’s foothill location creates duct problems that coastal crews don’t see. Fall Santa Ana winds blast fine desert dust and wildfire ash through the San Gabriel Mountain passes, and that material loads up in return ducts even in homes whose windows stayed closed. Our techs carry Rotobrush rotary brush systems and Nikro negative-air machines, the same tools commercial crews use, because residential ductwork here often needs commercial-grade extraction. We serve Upland from our Inland Empire office, with scheduling coordinated locally.
Residential Air Duct Cleaning in Upland
Residential Air Duct Cleaning in Upland means source-removal cleaning of your entire forced-air system: supply ducts, return ducts, trunk lines, and the air handler cabinet. For homeowners also concerned with fire safety and efficiency, our Dryer Vent Cleaning in Upland addresses another common source of lint buildup and hazard. We don’t just wipe registers and call it done. In Upland’s climate, with HVAC systems running almost year-round and Santa Ana winds driving ash and grit indoors, the actual contamination sits deep in the duct runs and around the blower motor. A typical residential job in Upland runs $350 – $650 depending on system size, duct material, and accessibility.
Full System Cleaning vs. Register-Only Work
Some outfits clean only what you can see: the grille face and maybe a foot of duct behind it. That’s not source removal. Our full system cleaning runs rotary brushes and negative-air agitation through every accessible supply and return run, extracting debris at the collection point rather than blowing it back into your living space. In Upland, where ash particles are fine enough to pass through standard filters, this matters.
Video Inspection Before and After
We run a camera through key sections of your ductwork before we quote and after we finish. You’ll see the ash load, the collapsed flex, or the rodent damage before we start, and you’ll see the clean duct after. No guesswork. No “trust us, it’s clean.”
Commercial Air Duct Cleaning in Upland
Commercial Air Duct Cleaning in Upland covers office buildings, retail spaces, medical clinics, and multi-tenant properties along Foothill Boulevard, in the Colonies Crossroads area, and throughout the city’s commercial corridors. These systems move more air, serve more occupants, and face heavier loading from foot traffic and outdoor air intakes. A typical commercial duct cleaning in Upland starts around $800 and scales with system complexity, square footage, and access requirements.
Scheduled Maintenance Programs
Commercial HVAC in Upland runs hard through hot inland summers. We set up quarterly or semi-annual cleaning schedules tied to your equipment’s runtime, not a calendar date pulled from thin air. Written scope, written price, same crew accountability each visit.
Minimal Disruption to Operations
We work around your hours. Early mornings, evenings, weekends. Our techs arrive uniformed and badged, scope the job on arrival, and stick to the written price. No surprises for your facilities manager or your tenants.

Common Air Duct Cleaning Problems We See in Upland Homes
- Post-Santa Ana ash loading in return ducts. After a wind event, we often find a visible gray film of fine ash inside return grilles and on filter frames, even in homes whose windows never opened. This ash is windborne from the San Gabriel foothills and passes right through standard fiberglass filters.
- Collapsed 1970s flex duct in east-side tract homes. The thin flex runs installed in Upland’s 1960s-70s building boom have degraded over fifty-plus years. They’re often crushed at joist penetrations, torn by prior rodent activity, or sagging with accumulated debris. Cleaning a collapsed section without repairing it just redistributes the contamination.
- Original unlined metal ductwork in downtown bungalows. Those 1920s citrus-belt homes near Historic Downtown Upland have character, but their original galvanized steel ducts have no internal lining. Rust scale, old construction debris, and decades of dust adhere to bare metal. Source removal works, but it takes the right agitation tools and controlled suction.
- Fogging “sanitiser” upsells that miss the actual problem. In Upland’s dry foothill climate, the real contaminant is windblown grit and ash, not microbial growth. A chemical fog leaves the source material in the duct and adds an unnecessary upsell. We don’t sell it.
Pricing for Air Duct Cleaning in Upland, CA
Here’s what air duct cleaning costs in Upland’s market:
- Small residential system (up to 12 vents): $350 – $450
- Mid-size residential system (13 – 20 vents): $450 – $550
- Large residential system (21+ vents or multiple zones): $550 – $650
- Commercial systems: $800 and up, scoped per job
What moves the price: duct material (metal vs. flex vs. fiberboard), accessibility (crawl space vs. attic vs. basement), contamination level (standard dust load vs. post-wildfire ash), and whether we find collapsed or damaged sections needing repair before cleaning. In cases where leaks are the main issue rather than debris, our Duct Sealing in Upland may be the more cost-effective solution. We give you one flat price per system, agreed in writing before any work starts. No per-vent add-ons. No equipment fees that appear at the door. Call (361) 326-5060 for a free estimate.

FAQs About Air Duct Cleaning in Upland
Yes, but for different reasons. Upland’s Santa Ana wind exposure and foothill location drive fine dust and wildfire ash into HVAC systems that coastal cities don’t experience. Where coastal homes fight humidity and salt-air corrosion, Upland homes accumulate dry grit and occasional ash. We typically recommend cleaning every 3 – 5 years for Upland residences, sooner after major wind events or nearby fires. Call (361) 326-5060 to schedule an inspection.
A real duct cleaning physically removes source material: rotary brushes knock debris loose, negative-air machines suck it out at the collection point, and the duct is left empty, not just scented. A fogging treatment sprays chemical into the duct without removing the ash, dust, or debris that’s actually there. In Upland’s dry climate, the problem is particulate load, not bacteria. Fogging doesn’t fix that. We don’t sell it.
It’s common in Upland, but it shouldn’t be ignored. That gray dust is likely windborne ash and fine desert grit passing through your filter. Standard pleated filters don’t catch particles below about 3 microns, and Santa Ana ash is often smaller. A homeowner near the Colonies called us after their 2003-built house kept smelling like a campfire two weeks after the Mountain Fire. Our tech pulled the return grille in the hallway and found a visible gray film of ash coating the filter frame and the first six feet of the flex run. We ran a camera inspection down the run, found a partially collapsed section near a joist, and used negative pressure with agitation tools to pull the ash out instead of blowing it back into the living space. If you’re seeing this signature, call (361) 326-5060 for a camera inspection.
Maybe, but we need to find the source first. Musty smells in 1920s-era downtown bungalows often come from moisture intrusion at the foundation or roof, not the ducts themselves. If the ductwork is clean and the smell persists, the problem is likely building envelope, not HVAC. We run a video inspection to rule out duct-related causes before we quote cleaning. If it’s not a duct problem, we’ll tell you. Call (361) 326-5060 and we’ll scope it.
We camera every flex run before we quote. If the duct is intact with normal dust loading, source-removal cleaning makes sense. If we find tears, collapsed sections, or rodent damage, cleaning alone is a waste: you’ll pay to have debris aerosolized that the blower motor then spreads through the house. Replacement is the right call. We show you the camera footage and explain both options with written prices for each. No pressure either way. Call (361) 326-5060 to schedule a look.
