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 Dryer Vent Cleaning Across San Dimas
Dryer vent cleaning in San Dimas typically runs $180 – $340 for a standard single-system home, and our crews schedule within a few days of your call. If you’re on Via Verde Drive, in the foothill neighborhoods near San Dimas Avenue, or down in the older tract homes off Arrow Highway, we know the vent runs you’re dealing with. San Dimas sits where dry desert winds meet the San Gabriel Valley, and that combination loads dryer vents with more than ordinary lint. Call (361) 326-5060 for a free estimate and we’ll give you a written price before any work starts.
Our Dryer Vent Cleaning team dispatches from our Los Angeles office, but the crews serving San Dimas live in the area and know the local housing stock. That matters because a 1970s tri-level off Bonita Avenue has a different vent run than a custom foothill home on a multi-acre lot. We show up uniformed, background-checked, and equipped with Rotobrush rotary agitation tools and Nikro negative-air machines with HEPA filtration, the same gear commercial crews use. The Garrison Standard means we arrive inside the quoted window, price in writing, complete the job by the book, and leave the site clean.
Why Hollis Air Duct Cleaning Is San Dimas’s Preferred Dryer Vent Cleaning Company
We’ve been in business since 2004 as part of the Garrison Partners family, and our track record predates most of the competitors you’ll find in San Dimas today. That longevity matters because dryer vent work is invisible, you can’t see inside the run, and homeowners need a company that will still be around if something fails. Our 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.
San Dimas homeowners call us because we price before we touch anything. No estimates that balloon once the technician is inside. No per-vent add-ons that turn a quoted $180 into a $500 invoice. One flat price per system, agreed in writing, and it does not move at the door. Our technicians are background-checked and uniformed, you know who is walking into your home before they arrive, and our 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.
We know San Dimas’s specific failure patterns. The same dry, brush-laden air that feeds the equestrian lots and hillside acreage also pushes fine trail dust and animal dander into dryer vents and exterior dryer vent hoods, so the lint plume outdoors often carries grit that never shows up in a coastal city’s dryer vent. After Santa Ana wind events, we routinely find a fine ash layer coating the outside flap and the first few feet of the dryer vent run in foothill-area homes. Local knowledge like that is why San Dimas homeowners stay with Hollis.
Dryer Vent Installation in San Dimas
Dryer Vent Installation in San Dimas becomes necessary when the existing vent run is too long, too corroded, or routed through multiple walls in a way that creates fire risk or drying inefficiency. In San Dimas’s larger foothill homes, we regularly see original installations that exceed the 25-foot maximum run length recommended by manufacturers, especially when the laundry room sits in the center of the house and the vent path has to navigate around staircases or second-floor joists. A proper installation in San Dimas runs $450 – $850 depending on run length, wall penetration count, and whether we need to install a booster fan for extended vertical runs.
When Rerouting Makes Sense
Sometimes the shortest path isn’t the existing path. We reroute dryer vent runs in San Dimas homes where the original contractor ran duct through an unconditioned attic or crawl space, creating condensation points that wet the lint and accelerate corrosion. A reroute through an interior wall with proper slope and support eliminates those low points and brings the run into code compliance.
Bird Guard and Exterior Hood Upgrades
San Dimas’s proximity to the Angeles National Forest means birds, rodents, and insects investigate exterior vent hoods more aggressively than in denser urban areas. We install Guardsman bird guards and proper backdraft dampers that seal when the dryer isn’t running, keeping wildlife out while maintaining airflow efficiency.
Dryer Vent Repair in San Dimas
Dryer Vent Repair in San Dimas addresses the specific deterioration patterns this climate creates. The hot-summer Mediterranean weather, combined with Santa Ana wind events that drive fine ash and debris into exterior components, corrodes galvanized ductwork and degrades flexible transition hoses faster than in coastal zones. Repair work in San Dimas typically costs $220 – $480, depending on whether we’re replacing a crushed section, re-supporting a sagging run, or rebuilding the exterior hood assembly.
Sag and Separation in Long Runs
Long dryer vent runs in larger foothill-area homes with multiple HVAC systems are often paired with overlong or poorly supported vent runs that sag and collect lint at low points. A quick trap-level cleaning misses the real blockage. We inspect with a camera, mark the sag points, and reinstall with proper supports and slope so lint moves through instead of settling.
Corrugated Original Ductwork
Original galvanized or early flexible dryer vent ductwork common in San Dimas’s 1960s – 1980s tract homes is usually a corrugated lint trap, and those hidden ridges and corrugations hold debris that a vacuum-only visit never removes. When we find crushed or separated sections in these older runs, we replace with smooth-wall aluminum duct that meets current California building code and dramatically reduces future lint accumulation.
Trusted Brands We Service in San Dimas
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation of compacted lint, Nikro negative-air machines for source removal under controlled suction, and filtration products from Honeywell, Aprilaire, and Guardsman. We stock common vent caps, bird guards, and transition hose sizes for San Dimas customers, so most repairs don’t require a second trip. When a foothill home needs a booster fan for a 35-foot vertical run, we source commercial-grade components that match the specifications of the original dryer manufacturer. The tools matter because a homeowner in San Dimas can’t verify the work visually, they have to trust that the equipment and the technician’s method actually removed the buildup.
Common Dryer Vent Cleaning Problems We See in San Dimas Homes
- Santa Ana ash infiltration. After Santa Ana wind events, fine ash and trail dust enter through the exterior dryer vent hood and get pulled into the lint pathway, so the visible lint trap looks fine while the run is loaded with abrasive grit that wears the transition duct. We find this most often in homes near the foothills, where the wind velocity is higher.
- Overlong runs in multi-system homes. San Dimas properties with three HVAC systems often have correspondingly complex laundry arrangements, with dryer vent runs that exceed safe lengths and include multiple elbows. These configurations dry slowly and create hidden fire risks that standard cleaning doesn’t address.
- Original corrugated ductwork in tract homes. The 1960s – 1980s housing stock throughout San Dimas frequently contains flexible foil or early semi-rigid duct with deep corrugations. Each ridge traps lint, and after decades of accumulation, airflow drops by 50 percent or more before the homeowner notices longer dry times.
- Equestrian and trail dust loading. Homes near the equestrian districts and properties backing open space see finer particulate matter in their dryer vents, a combination of lint, animal dander, and mineral dust from the trails. This mixture compacts harder than pure lint and requires rotary agitation, not just suction, for complete removal.

We do not quote per-vent prices that balloon at the door. One flat price per system, written down before work starts, guaranteed not to change. Every San Dimas job includes before-and-after photos of your specific vent run, so you see what came out even though you can’t see inside the duct yourself.

FAQs About Dryer Vent Cleaning in San Dimas
San Dimas’s combination of dry desert winds, equestrian activity, and Santa Ana events introduces fine trail dust and ash into the lint pathway, creating a grittier, more compacted buildup than coastal areas see. The exterior hood and first few feet of run collect this material even when the interior lint trap looks normal. Call (361) 326-5060 for an inspection if your dry times have increased without an obvious cause.
Yes. Multi-system homes in San Dimas often have longer, more complex dryer vent runs with multiple elbows or booster fans that require camera inspection and rotary agitation tools to clean properly. We price by the system, not by the foot, so a long run doesn’t trigger surprise add-ons. The written quote covers the complete lint pathway from dryer to exterior hood.
Yes, we repair and replace damaged galvanized and early flexible ductwork common in San Dimas’s 1960s – 1980s housing stock, upgrading to smooth-wall aluminum where code requires. We also re-support sagging runs and rebuild exterior hood assemblies damaged by Santa Ana wind debris. The repair is covered by our 365-Day Done Right Promise.
Every Hollis job includes before-and-after photos of your specific vent run, taken with our inspection camera, plus airflow measurements at the exterior hood before and after cleaning. You receive written documentation of what was removed and how airflow improved. If the work fails within a year, we return at no charge under our 365-Day Done Right Promise.
Most San Dimas homes need dryer vent cleaning every 12 – 18 months, but foothill properties exposed to heavier trail dust and Santa Ana ash may need service annually. If your dryer takes longer than one cycle, the laundry room feels humid, or you notice reduced airflow at the exterior hood, schedule an inspection regardless of the calendar. Call (361) 326-5060 for a free estimate.
