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.

We’ve worked in Claremont long enough to know the difference between a 1920s College Heights bungalow with converted gravity-furnace ducts and a 1980s tract home off Foothill Boulevard. That matters because the cleaning approach changes completely. In Claremont, the Santa Ana winds push fine alluvial silt through poorly sealed return systems, and the hot, dry summers mean HVAC equipment runs hard from May through October. Our Air Duct Cleaning team shows up with rotary brush systems, negative-air machines, and the patience to inspect before quoting.
Why Hollis Air Duct Cleaning Is Claremont’s Preferred Air Duct Cleaning Company
We’ve been part of the Garrison Partners family since 2004. The Garrison Standard means written prices, written guarantees, and a 365-Day Done Right Promise on every job. In Claremont, that standard matters because too many homeowners have watched a low teaser price balloon once the truck is in the driveway.
Our technicians are background-checked and uniformed. You know who’s arriving before they knock. The price we write down before any work starts is the price you pay. 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, seven days a week. No voicemail loops. No waiting until Monday.
We know Claremont’s local conditions. The combination of older, tightly sealed homes built before the 1980s and extreme seasonal dust events means our crews focus on removing fine alluvial silt that infiltrates through return leaks, not just the pet dander or pollen typical of other markets. This is different from neighboring Upland or La Verne, where newer construction brings different sealing challenges.
Commercial Air Duct Cleaning in Claremont
Commercial Air Duct Cleaning in Claremont covers office buildings, retail spaces, medical clinics, and multi-tenant properties where code compliance and occupancy health standards require documented cleaning intervals. A typical commercial system in Claremont runs $800 – $2,400 depending on square footage, duct complexity, and access. We schedule around business hours, coordinate with property managers, and provide before-and-after photo documentation.
Code-Compliant Documentation
Claremont commercial properties often need cleaning records for insurance, lease agreements, or municipal inspection. We document each run with video inspection footage and written condition reports. Our crews use Nikro negative-air machines to maintain containment during the job, so occupied spaces stay operational.
Multi-Zone System Expertise
Commercial buildings near the Claremont Colleges or along Indian Hill Boulevard frequently have multi-zone HVAC with rooftop units and extensive horizontal duct runs. We clean supply and return trunks separately, seal access panels properly, and verify airflow balance before signing off.
Air Duct Cleaning Services in Claremont
Air Duct Cleaning Services in Claremont include full system cleaning, supply and return duct cleaning, video inspection, and duct sealing for residential and light commercial properties. A typical residential job in Claremont runs $350 – $650 for a complete system, with older homes or converted gravity-furnace systems sometimes requiring additional access work. We use Rotobrush rotary brush systems for mechanical agitation and Nikro negative-air equipment for source removal, not just surface vacuuming.
Video Inspection Before Quoting
We run a camera first. In Claremont’s historic neighborhoods, we regularly find disconnected runs, collapsed flex duct, and alluvial silt packed into low-velocity sections. Seeing the actual condition lets us quote accurately and avoids the “surprise” upsell once work begins.

Duct Sealing After Cleaning
Clean ducts with open seams just get dirty again. We seal accessible joints with mastic after cleaning, especially in older homes where original sheet-metal connections have loosened over decades. This step is part of The Garrison Standard, not an add-on.

Trusted Brands We Service in Claremont
Our equipment roster includes Rotobrush rotary brush systems, Nikro negative-air machines, and filtration products from Honeywell, Aprilaire, and Guardsman. We stock Guardsman HEPA filters and Honeywell media replacements for Claremont customers who want to maintain results between cleanings. Most common sizes are available without a special order, so turnaround stays short. For properties near the colleges or in the Village with sensitive occupants, we specify Abatement Technologies HEPA containment to keep particulate out of living spaces during the job.
Common Air Duct Cleaning Problems We See in Claremont Homes
- Alluvial silt infiltration through return leaks. Claremont’s position at the base of the San Gabriel Mountains means Santa Ana winds drive fine dust from the wash into attic and crawlspace duct systems. Crews that skip source removal and negative pressure leave that silt recirculating indefinitely.
- Disconnected runs in converted gravity-furnace homes. In College Heights and Old Claremont, 1920s – 40s gravity furnaces were later converted to forced-air, but the original sheet-metal ducts were rarely resized or sealed. Technicians often find three or more disconnected runs that a simple vacuuming cannot address.
- Asbestos-wrapped ducts in pre-1980s homes. Some older Claremont properties still have asbestos-wrapped ductwork. Disturbing these wraps without proper abatement protocols creates a health hazard and violates NADCA standards. We identify these conditions during video inspection and coordinate appropriate handling.
- Undersized ducts creating low-velocity dust accumulation. Original sheet-metal ducts in converted systems were sized for gravity airflow, not forced-air volume. Dust packs into low-velocity sections where standard cleaning heads cannot reach, requiring agitation tools and extended negative-pressure cycles.
Pricing for Air Duct Cleaning in Claremont, CA
Honest pricing means ranges you can plan around, not a teaser that doubles at the door. In Claremont’s current market, a typical residential full-system cleaning runs $350 – $650. Commercial systems start around $800 and range to $2,400 for larger or more complex buildings. Supply-only or return-only cleaning runs $180 – $320. Video inspection as a standalone service is $120 – $180, though we include it in most full-system quotes.
What moves the price: system size, access difficulty (crawlspace vs. attic vs. basement), condition of ductwork, and whether sealing or repair work is needed. Older homes in College Heights or the Avenues often require additional access panels or extended agitation time. We write the price before touching anything. One flat price per system. No per-vent pricing. No add-ons after the fact. Call (361) 326-5060 for an exact quote. Estimates are free.

FAQs About Air Duct Cleaning in Claremont
Every three to five years for most Claremont homes, though properties near open land or with unpaved access roads may need cleaning every two to three years due to heavier dust loading. The Santa Ana winds and alluvial dust from the wash accelerate accumulation in poorly sealed return systems. Call (361) 326-5060 to schedule an inspection and we’ll tell you where your system stands.
Converted gravity-furnace systems in College Heights and Old Claremont retain original sheet-metal ducts that were rarely resized or properly sealed for forced-air operation. Our technicians routinely find disconnected runs and packed alluvial silt that standard vacuuming cannot remove. Camera inspection and mechanical agitation are required, not optional, in these homes. Call (361) 326-5060 for a free estimate.
Yes, we identify asbestos-wrapped ducts during video inspection and coordinate proper abatement protocols before disturbing any material. We do not remove or disturb asbestos-containing materials ourselves; we work with certified abatement contractors when needed. This protects both occupants and technicians, and it keeps the job compliant with NADCA and California standards. Call (361) 326-5060 to discuss your specific situation.
Supply ducts push conditioned air into rooms; return ducts pull air back to the handler. In Claremont, return ducts are typically the dirtier of the two because they draw in unfiltered air from attic and crawlspace leaks, especially during Santa Ana wind events. We clean both separately with dedicated tools, but we often find return systems require more aggressive agitation and longer negative-pressure cycles. Call (361) 326-5060 for a system-specific quote.
Yes. Commercial systems in Claremont are larger, more complex, and subject to code requirements for documentation and occupancy health standards. We use Nikro negative-air machines for containment, provide video inspection records, and schedule around business hours to minimize disruption. Typical commercial pricing runs $800 – $2,400 depending on system size. Call (361) 326-5060 to discuss your building’s requirements.
On a 1928 bungalow in College Heights, our tech pulled a camera inspection through the original sheet-metal supply and return ducts and found three disconnected runs plus a heavy layer of fine alluvial silt from the wash. We set up negative pressure with HEPA filtration, used agitation tools to loosen the packed dust, and sealed the open joints before cleaning the air handler and blower motor. The homeowner immediately noticed stronger airflow at the registers and less dust settling on furniture.
