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 La Crescenta-Montrose’s Preferred Air Duct Cleaning Company
We’ve been serving foothill communities since 2004 as part of the Garrison Partners family, and La Crescenta-Montrose is one of the most demanding duct environments we work in.

The 365-Day Done Right Promise backs 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. Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No callback queues.
Air Duct Repair in La Crescenta-Montrose
Air Duct Repair in La Crescenta-Montrose usually addresses the failures we find inside original 1950s galvanized trunks and the mixed flex-run additions common in Foothill Boulevard corridor homes. A typical repair runs $180 – $450 depending on whether we’re reconnecting a crushed branch, replacing a disconnected return boot, or sealing degraded batt wrap that’s letting attic air into the system. Most La Crescenta-Montrose houses we enter have been re-ducted in stages, so one repair often uncovers two more issues that need documenting.
Galvanized Trunk Restoration
Original steel trunks in La Crescenta-Montrose homes corrode at seams and collect decades of compacted debris that rotary brushes alone won’t dislodge. We cut access panels where needed, source-remove the buildup with negative-air agitation, then seal with mastic rated for the temperature swings these attics see.
Flex Run Reconnection and Sealing
Newer flex runs in shallow attics get crushed by storage boxes, degraded by heat, or pulled loose from collars during prior service. We inspect with a camera before declaring any run clean, then reconnect and support properly so the repair lasts past the next wind season.
Ductwork Cleaning in La Crescenta-Montrose
Ductwork Cleaning in La Crescenta-Montrose means more than register vacuuming. A full system job for a typical 1,500 – 2,500 square foot home runs $350 – $650 and includes supply ducts, return ducts, the air handler cabinet, and the blower motor. Because of the local wind and fire exposure, our standard here includes before/after photo documentation that many homeowners keep for insurance purposes. We use Rotobrush rotary brush systems under Nikro negative-air containment to keep debris from re-entering the living space during cleaning.
Post-Wind Ash Source Removal
After a red-flag event, registers in La Crescenta-Montrose can keep shedding visible ash for weeks. We don’t just clean what you can see. We pull the blower assembly and clean the evaporator coil area where fine particles settle and recirculate each cycle.
Mixed System Protocol
Homes with old galvanized trunks and newer flex runs require different agitation methods for each material type. We inspect every run with a camera first, then match the tool to the duct, not the other way around.
Trusted Brands We Service in La Crescenta-Montrose
Our equipment roster includes Rotobrush rotary brush systems and Nikro negative-air machines for the cleaning itself, plus filtration and sealing products from Aprilaire, Abatement Technologies, and Guardsman. We stock common fittings and collar sizes for the mixed duct systems typical in La Crescenta-Montrose’s mid-century housing stock, which keeps turnaround fast when a repair follows the cleaning. Our Air Duct Cleaning team carries the full range of mastics, tapes, and mechanical fasteners needed to seal original galvanized seams and secure flex runs to modern standards.
Common Air Duct Cleaning Problems We See in La Crescenta-Montrose Homes
- Wildfire ash accumulation in return plenums. After any fire in the Verdugos or Angeles National Forest, fine ash works through soffit vents and attic penetrations, settling in the return side where standard filter changes won’t reach it.
- Disconnected runs buried under degraded attic insulation. Original batt wrap crumbles in La Crescenta-Montrose’s hot summer attics, hiding separations at flex-to-trunk connections that leak conditioned air and pull in attic dust.
- Crushed flex runs from shallow attic storage. Homeowners in the Honolulu Avenue and Rosemont Avenue neighborhoods often use their limited attic space for storage, compressing newer flex ducts against the original galvanized.
- Blower motor loaded with compacted debris. Years of dust, ash, and pollen bypassing clogged filters cakes onto the blower wheel, reducing airflow and forcing the system to run longer in summer heat.

FAQs About Air Duct Cleaning in La Crescenta-Montrose
Wait until the air quality index returns to normal levels, then schedule within two to four weeks. Ash continues settling during wind events, so cleaning too early means you’ll just recollect debris. Call (361) 326-5060 and we’ll assess whether your system needs immediate attention or can wait for the wind pattern to stabilize.
It removes decades of accumulated debris from original galvanized trunks, restores airflow reduced by compacted blower dust, and identifies disconnects or crushed runs that waste energy. The real fix often includes sealing work after cleaning, since mid-century systems weren’t designed for modern efficiency standards. We document everything with photos.
NADCA provides a useful benchmark, but our standard exceeds it for La Crescenta-Montrose conditions because of local fire and wind exposure. We follow The Garrison Code: full source removal, mechanical agitation, negative-air containment, and photo documentation of every job. That’s the standard we put in writing.
Yes, and we must use different methods for each. Galvanized trunks need rotary brush agitation and seam sealing; flex runs need gentler negative-air cleaning and physical support to prevent crushing. We camera-inspect every run first to determine the right approach for that specific duct.
Cleaning removes the source of ash odors trapped in ductwork and the blower assembly, but persistent smoke smell may also require filter replacement and possibly cleaning of porous surfaces in the home. We evaluate the full system and tell you honestly whether duct cleaning alone will solve it or if additional steps are needed. Call (361) 326-5060 for an assessment.
