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 Morgan Hill
Air duct cleaning in Morgan Hill typically runs $350 – $650 for a full residential system, with most jobs completed in a single morning or afternoon. If you’re smelling smoke weeks after wildfire season, seeing dust blow from registers right after cleaning, or your 1990s tract home has never had its ducts opened up, you’re dealing with problems that standard vacuuming won’t fix. Call (361) 326-5060 for a free estimate with a written price before any work starts.
We’ve worked through enough homes off Monterey Road and in the neighborhoods around Paradise Valley to know what Morgan Hill ductwork actually looks like: slab foundations, original flex-duct runs from the 1980s through the early 2000s, and taped joints that have been baking in the crawl space for twenty to forty-five years. Our crews serve Morgan Hill from the San Francisco Bay Area office, dispatching with Rotobrush rotary systems and Nikro negative-air equipment, not hardware-store gear. When we quote a job in Morgan Hill, we quote it for the actual condition of the system, not a teaser rate that doubles once we’re inside.
Why Hollis Air Duct Cleaning Is Morgan Hill’s Preferred Air Duct Cleaning Company
Hollis Air Duct Cleaning has been part of the Garrison Partners family since 2004. That track record predates most of the duct-cleaning outfits advertising in Santa Clara County right now. We’re not a franchise with a script; each Hollis location is independently owned and operated under The Garrison Standard, which means written prices, written guarantees, and technicians who arrive inside the quoted window.
Our Air Duct Cleaning in Morgan Hill crews are background-checked and uniformed. You know who’s walking into your home before they arrive. The 365-Day Done Right Promise covers 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. No negotiation, no runaround.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday to schedule. In Morgan Hill, where fire season can turn air quality from clear to hazardous in a single afternoon, that accessibility matters.
We price in writing before any work starts. The number on the page is the number at the door. We’ve heard too many stories from Morgan Hill homeowners about quotes that jumped once the van was in the driveway. That doesn’t happen here.
Commercial Air Duct Cleaning in Morgan Hill
Commercial Air Duct Cleaning in Morgan Hill covers office parks along Cochrane Road, retail spaces near East Dunne Avenue, and smaller professional buildings throughout the 95037 zip code. These systems run harder and longer than residential units, often with rooftop package units feeding a maze of rigid metal trunk lines and flex drops that haven’t been opened in a decade or more. We use Nikro negative-air machines and Rotobrush agitation tools to dislodge and extract buildup without contaminating occupied spaces. A typical commercial system in Morgan Hill runs $800 – $2,500 depending on square footage, access difficulty, and whether video inspection reveals disconnected runs or failed sealing.
Office and Retail Systems
Office buildings in Morgan Hill often share a common failure mode: rooftop units pulling agricultural dust and wildfire ash through economizer dampers that don’t seal properly. We inspect damper operation, clean the full return and supply paths, and document before-and-after conditions with camera footage you can show your property manager or landlord.
Restaurant and Food-Service Exhaust
Kitchen exhaust and make-up air systems in Morgan Hill restaurants require a different approach than standard HVAC duct cleaning. Grease-laden vapors coat the interior of exhaust ducts, creating fire hazards and airflow restrictions. We coordinate with your hood-cleaning schedule and use Abatement Technologies HEPA containment to protect dining areas during the process.
Air Duct Cleaning Services in Morgan Hill
Air Duct Cleaning Services in Morgan Hill start with a full-system inspection, not a blind vacuum job. We look at the air handler, the return plenum, every accessible trunk line, and each register drop. For the typical 1,500 – 2,500 square foot home in the Madrone or Jackson Oaks neighborhoods, that means checking roughly 15 – 25 duct runs, testing static pressure, and photographing conditions before we touch anything. A complete residential cleaning in Morgan Hill runs $350 – $650; duct sealing adds $200 – $400 if we find separated joints or sagging flex runs behind the air handler.
Supply and Return Duct Cleaning
Supply ducts push conditioned air to your rooms. Return ducts pull it back. In Morgan Hill’s slab-foundation homes, return ducts often run through the concrete perimeter or through soffits with the tightest bends, making them the first place we find crushed flex or separated tape. We clean both sides of the system because cleaning only the supplies leaves the return side recontaminating everything within days.
Video Inspection and Documentation
Our camera inspection shows you what we see: the crushed run behind the air handler, the three inches of settled ash in the return trunk, the taped joint that’s been leaking attic air for fifteen years. You get the footage. We explain what needs cleaning, what needs sealing, and what can wait. No guesswork, no pressure.

Trusted Brands We Service in Morgan Hill
We stock and install filtration and sealing products from Aprilaire, Abatement Technologies, and Guardsman for Morgan Hill homes, with turnaround times that don’t leave you running on a dirty system while parts ship from out of state. Aprilaire media air cleaners handle the pollen load from Morgan Hill’s surrounding orchards and oak woodlands without the airflow restriction that chokes older flex-duct systems. Abatement Technologies HEPA filtration captures the fine wildfire ash that standard pleated filters miss. Guardsman duct sealing products close the gaps we find at taped joints and crushed runs. When we recommend a product for your Morgan Hill home, it’s because we’ve seen it work in conditions like yours, not because it’s the most profitable add-on.
Common Air Duct Cleaning Problems We See in Morgan Hill Homes
- Crushed flex runs behind slab-foundation air handlers. In 1990s two-story tract homes off East Main and Monterey Road, the flex duct feeding upstairs registers gets compressed against the concrete slab or pinched by a careless retrofit. Airflow drops. The system runs longer. Ash and pollen recirculate instead of being filtered out.
- Separated taped joints re-entraining wildfire ash. Original duct tape on twenty-year-old flex joints dries and fails. During fire season, when Morgan Hill homes run closed recirculation for weeks, fine ash that settles in the return trunk gets pulled back through these gaps and blown into living spaces. Cleaning without sealing just resets the clock.
- Mismatched MERV ratings damaging already-stressed systems. A MERV 13 filter in a system with 1980s flex duct and a standard blower motor chokes airflow, increases static pressure, and pulls loose joints apart faster. Meanwhile, a MERV 8 lets orchard pollen and ash coat the blower wheel and evaporator coil, reducing efficiency and spreading contaminants.
- Smoke odor persistence long after visible smoke clears. We hear this constantly from homeowners near Anderson Lake and the rural edges of Morgan Hill: new filters installed, windows closed, but the house still smells like campfire every time the AC kicks on. The ash isn’t in the filter. It’s in the duct runs, and standard residential vacuums don’t have the suction or containment to remove it.
Pricing for Air Duct Cleaning in Morgan Hill, CA
A typical residential Air Duct Cleaning in Morgan Hill runs $350 – $650 for a full system, including supply and return ductwork, register cleaning, and air-handler access. Duct sealing, when we find separated joints or sagging flex runs, adds $200 – $400. Commercial systems start around $800 and scale with square footage and access complexity. Video inspection is included in the estimate; you see what we see before deciding.
What moves the price: number of duct runs, accessibility (crawl space vs. attic vs. slab with limited access), condition of existing ductwork, and whether fire-season ash removal requires extended agitation and HEPA containment. We give one flat price per system, agreed in writing before work starts. No per-vent pricing. No invoice that balloons once the technician is inside.

FAQs About Air Duct Cleaning in Morgan Hill
The ash has settled in your duct runs, not just your filter. During fire season, Morgan Hill homes run closed recirculation for weeks; fine ash that makes it past the filter deposits in supply and return ducts, then re-enters the air stream every time the blower cycles. Standard filter changes don’t remove duct contamination. We use Nikro negative-air containment and Rotobrush agitation to extract settled ash, with HEPA filtration so it doesn’t re-enter your home. Call (361) 326-5060 for an inspection and exact quote.
Most 1990s slab-foundation flex duct in Morgan Hill is cleanable and sealable if the material itself isn’t deteriorated. We camera-inspect first. If we find crushed runs, separated joints, or moderate debris, cleaning plus duct sealing ($350 – $650 plus $200 – $400 for sealing) usually restores airflow and removes contamination. Replacement becomes the better option only when the flex liner is breaking down, which we can show you on camera. The 365-Day Done Right Promise covers our sealing work; if joints fail within a year, we return at no charge.
Morgan Hill’s warm inland climate and surrounding agriculture create a heavier pollen load than fog-buffered Bay Area cities to the north. Oak pollen peaks in spring; orchard dust runs through summer harvest. If you have allergy-sensitive occupants or run your system with windows closed through pollen season, duct cleaning every three to five years prevents buildup that overwhelms standard filtration. Homes with original 20 – 45-year-old flex duct may need more frequent inspection because loose joints let unfiltered attic air bypass the system entirely.
We use professional-grade Nikro negative-air machines with HEPA filtration on every Morgan Hill job, residential and commercial. A shop vac blows fine ash and pollen back into your living space through its exhaust. Our negative-air setup creates suction at the collection point, contains debris in sealed drums, and exhausts through HEPA filters rated at 99.97% efficiency at 0.3 microns. That’s the standard for wildfire ash removal, and it’s what we bring to every Morgan Hill home.
Most Morgan Hill homes with standard flex-duct systems should run MERV 8 – 11, not higher. MERV 13 and above capture more particles but restrict airflow enough to stress older blowers and pull loose duct joints apart. If you’re dealing with active wildfire smoke, upgrade to a MERV 11 and change it monthly during fire season, rather than choking the system with a MERV 13. We check static pressure during every cleaning and can recommend the right filter for your specific system. Call (361) 326-5060 to schedule.
