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.
Fast, Reliable Air Duct Cleaning Across Rosemead
Air duct cleaning in Rosemead typically runs $350 – $650 for a full residential system, with most jobs completed in a single visit. We’re familiar with the specific ductwork found in Rosemead’s post-war neighborhoods, from the stucco tracts near Rosemead Boulevard to the apartment complexes along Garvey Avenue. Our Air Duct Cleaning crews dispatch from our Los Angeles office and carry the rotary brush systems and negative-air equipment needed for the gravity-furnace ductwork common in homes built here between 1948 and 1965.

Why Hollis Air Duct Cleaning Is Rosemead’s Preferred Air Duct Cleaning Company
We’ve been serving the San Gabriel Valley since 2004 as part of the Garrison Partners family, and Roy Castellanos has built our Rosemead reputation on one principle: say what you’ll do, write down the price, then do exactly that. Our technicians are background-checked and uniformed, and they arrive inside the quoted window – not “sometime between 8 and 5.”
Every job starts with a written price before any work begins. That price does not move at the door. The 365-Day Done Right Promise covers every repair 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.
Vent Cleaning in Rosemead
Vent Cleaning in Rosemead means more than brushing off register covers. In the older tracts near Rosemead Boulevard, supply vents often connect to original uninsulated sheet-metal ductwork that runs through crawlspaces where rodents and moisture have had decades to compromise the system. We remove each vent cover, clean the boot and the first few feet of duct behind it, and inspect with a camera for disconnected runs or pest entry points. A typical vent cleaning as part of a full system service in Rosemead runs $45 – $85 per vent when bundled, or $150 – $300 as a standalone service for a limited vent count.
Supply Vent Cleaning
Supply vents push conditioned air into your rooms. In Rosemead’s 1950s stucco homes, these vents often sit low on walls and collect more dust and pet hair than ceiling-mounted systems in newer construction. We use Rotobrush rotary tools to agitate debris without damaging fragile original seams.
Return Vent Cleaning
Return vents pull air back to the blower. The single central floor return grille common in older Rosemead tracts is a choke point – we’ve found them packed solid with hair and debris that then circulates through the entire system. Cleaning this grille and the duct behind it restores airflow the homeowner can feel immediately.
Air Duct Repair in Rosemead
Air Duct Repair in Rosemead often starts with what we find during a cleaning. The original sheet-metal ductwork in 1950s and 1960s tracts wasn’t built to last 70 years. We’ve found crushed runs in crawlspaces, disconnected joints where tape has dried and failed, and seams torn open by decades of thermal expansion. Repair work in Rosemead typically runs $200 – $500 for sealing and minor repairs, or $800 – $1,800 if sections of duct need replacement. We always inspect with a camera first, show you what we found, and write the repair price before touching anything.
Sealing and Rodent Exclusion
In Rosemead’s crawlspace-routed gravity systems, mechanical cleaning without sealing is temporary. We use duct sealing mastic and metal-backed tape to close entry points, then verify with a pressure test. This sequencing – seal first, clean second – is what makes the result last.
Crushed or Disconnected Run Repair
Original sheet-metal ducts in unconditioned crawlspaces get damaged by pests, moisture, or a contractor crawling past. We replace crushed sections with insulated flex duct where appropriate, or rebuild rigid connections where the original layout must be preserved.
Trusted Brands We Service in Rosemead
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines for HEPA-filtered debris removal, and filtration products from Honeywell, Aprilaire, and Guardsman. We stock common fittings and sealing materials locally, so Rosemead jobs don’t wait on parts. When a repair calls for a specific component, we source it fast – our technicians arrive with the inventory to handle most same-visit repairs without a return trip.
Common Air Duct Cleaning Problems We See in Rosemead Homes
- Gravity-furnace ductwork with no insulation. Rosemead’s 1948 – 1965 tracts were built with ducts that run through unconditioned crawlspaces. Without insulation, these ducts sweat in damp weather, attract pests, and lose conditioned air before it reaches the vent.
- Single central floor return grilles clogged with debris. In the older tracts near Rosemead Boulevard, one grille serves as the entire return path. When it’s packed with pet hair, the blower motor strains, airflow drops, and dust recirculates through every room.
- Rodent intrusion in crawlspace duct runs. San Gabriel Valley neighborhoods with mature trees and older construction see regular pest activity. Mice enter through gaps in foundation seals and nest in warm ductwork, leaving contamination that simple brushing won’t remove.
- Musty odors after winter rain. Rosemead’s mild, damp winters and occasional heavy rain can introduce moisture into poorly sealed crawlspace ducts. Combined with dust accumulation, this creates the moldy smell homeowners notice when the heater first runs in fall.
Pricing for Air Duct Cleaning in Rosemead, CA
A typical full system air duct cleaning in Rosemead runs $350 – $650 for a single-family home with 10 – 15 vents. This includes supply and return duct cleaning, vent cover removal and washing, and a basic camera inspection. Homes with the original gravity-furnace ductwork often need sealing and rodent exclusion first, which adds $200 – $500. If we find crushed or disconnected runs requiring repair, that work is priced separately at $200 – $500 for minor repairs or $800 – $1,800 for section replacement.
We do not quote per-vent teaser prices that balloon at the door. The price is written down before any work starts, and it does not move. Every estimate is free. Call (361) 326-5060 to schedule.

FAQs About Air Duct Cleaning in Rosemead
The odor comes from decades of dust, pest activity, and moisture in your original uninsulated sheet-metal ducts. Gravity-furnace systems in Rosemead’s post-war tracts pull air through crawlspaces that were never sealed against rodents or damp. We camera-inspect first, seal entry points, then clean with negative-air HEPA filtration. Call (361) 326-5060 for a free estimate.
Yes. Gravity-furnace ductwork runs at lower pressure and often lacks the plenum connections of modern systems. In Rosemead, this means the ducts are more susceptible to pest intrusion and seam separation. We seal before we clean, and we use lower-pressure agitation tools to avoid damaging fragile original metal. Call (361) 326-5060 to discuss your system.
It’s a single large grille, usually in a hallway or living room floor, that serves as the only return path for your entire system. In Rosemead’s 1950s neighborhoods near Rosemead Boulevard, this grille becomes packed with hair and debris that then gets pulled into the blower and redistributed. Cleaning this grille and the duct behind it is essential – we never skip it. Call (361) 326-5060 to schedule an inspection.
Cleaning removes mold growth, but the mold will return if moisture keeps entering through unsealed crawlspace ducts. In Rosemead’s climate, winter rain plus poorly sealed gravity-furnace systems equals recurring moisture. We clean the affected sections and seal the entry points – both steps are necessary for a lasting fix. Call (361) 326-5060 for an exact assessment.
Every 2 – 3 years, or immediately if you notice odors, visible dust, or uneven heating. Original sheet-metal ductwork in Rosemead’s unconditioned crawlspaces deteriorates faster than modern insulated systems. A camera inspection shows crushed runs, disconnected joints, and pest entry before they become expensive problems. Call (361) 326-5060 to book a free inspection.
