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 Sierra Madre’s Preferred Air Duct Cleaning Company
We’ve been in business since 2004 as part of the Garrison Partners family, and our Air Duct Cleaning in Sierra Madre reputation comes from showing up inside the window, pricing in writing before we touch anything, and leaving the site clean. Roy Castellanos, who leads Hollis, built this operation on The Garrison Standard: written prices, written guarantees, and technicians who are background-checked and uniformed on every job.
Sierra Madre homeowners know the bait-and-switch routine. A low coupon price, then the technician finds “extra vents” or “surprise contamination” and the bill doubles. We don’t operate that way. The price is written down before any work starts, and it does not move at the door. Every job carries our 365-Day Done Right Promise: if the work fails within a year, we return and make it right at no charge, including a free second visit.
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 to schedule.
HVAC Duct Cleaning in Sierra Madre
HVAC Duct Cleaning in Sierra Madre means pulling decades of packed dust, wildfire ash, and pollen from supply and return lines that were often installed when Truman was president. Most Sierra Madre homes we service were built between the 1920s and 1950s, with original galvanized or early sheet-metal ductwork that’s leaky, undersized, and prone to collecting debris. A typical residential HVAC duct cleaning in Sierra Madre runs $350 – $650 depending on system size and accessibility. We use Rotobrush rotary brush systems for mechanical agitation and Nikro negative-air machines to maintain controlled suction, so nothing gets blown into your living space during the job.
Supply Duct Cleaning
Supply ducts push conditioned air into your rooms. In Sierra Madre’s older homes, these lines often run through unconditioned crawl spaces or wall cavities where road dust and ash settle. We camera-inspect before and after so you see the difference.
Return Duct Cleaning
Return ducts pull air back to the handler. This is where wildfire ash typically enters, through gaps and leaks in the return path. Our negative-air method captures that debris at the source instead of redistributing it.
Vent Cleaning in Sierra Madre
Vent Cleaning in Sierra Madre covers the registers, grilles, and boot connections where dust and ash become visible to homeowners first. On historic properties near Sierra Madre Boulevard and the canyon roads, we regularly find vent covers caked with fine gray ash from the Bobcat Fire and subsequent fire seasons, plus the pollen load that comes with living under a heavy tree canopy. A standard vent cleaning as part of a full system service runs $350 – $650; standalone vent-only cleaning for smaller systems starts around $250. We remove each register, clean the boot and first few feet of duct, and reinstall everything properly.
Register and Grille Deep Cleaning
Registers trap the largest particles. We soak and hand-clean each one, then check the damper operation. Stuck dampers force your system to work harder and unevenly heat or cool rooms.
Dryer Vent Cleaning
Dryer vents are a separate fire hazard. In Sierra Madre’s rural parcels with longer vent runs to outbuildings, lint accumulation is worse than in compact suburban layouts. Dryer vent cleaning typically runs $150 – $250 when bundled with duct cleaning.
Trusted Brands We Service in Sierra Madre
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation inside duct walls, Nikro negative-air machines for controlled debris extraction, and filtration products from Aprilaire, Abatement Technologies, and Guardsman. These are the same tools commercial crews use, not hardware-store gear. For Sierra Madre homeowners with older systems, we stock compatible fittings and adapters for pre-1960s ductwork dimensions, which means faster turnaround and no waiting on specialty parts. When we encounter a Honeywell or Aprilaire media filter cabinet during a job, we carry the correct replacement sizes on our trucks.
Common Air Duct Cleaning Problems We See in Sierra Madre Homes
- Wildfire ash trapped in original galvanized ducts. After the 2020 Bobcat Fire, many Sierra Madre homeowners discovered their 1920s-era returns were pulling in ash through gaps and leaks. We still find fine gray residue in ducts along Sierra Madre Boulevard years later.
- Road dust loading on unpaved lanes and larger parcels. Homes on unpaved access roads add a year-round dust load that seasonal cleaning schedules miss. The canyon winds stir it up, and the HVAC system pulls it inside.
- Undersized ductwork struggling with modern equipment. Many Sierra Madre bungalows have 6-inch supply lines where 8-inch is now standard. The restricted airflow concentrates debris and accelerates buildup.
- Outbuilding and detached garage systems ignored. Larger Sierra Madre properties often have second duct runs to workshops, studios, or guest quarters. These become secondary dust and ash reservoirs that recirculate into the main house.

FAQs About Air Duct Cleaning in Sierra Madre
Every 2 – 3 years for the main system, and annually for dryer vents on properties with longer runs. The combination of wildfire ash residue, canyon-trapped pollen, and unpaved-road dust creates a heavier load than standard suburban environments. Homes with outbuilding duct runs should add those to the inspection cycle. Call (361) 326-5060 and we’ll build a schedule that matches your property.
Wildfire ash entered your return ducts through gaps and leaks, then settled in the air handler and blower motor where surface cleaning can’t reach it. The smell recirculates every time the system runs. Our field crew encountered this exact problem on a rural parcel off Sierra Madre Boulevard: a 1920s bungalow with original galvanized ducts pulling ash through leaky returns. We set negative pressure with HEPA filtration, used agitation tools on decades of packed dust, and camera-inspected the air handler. The ash in the returns explained the lingering smell and the extra load in the outbuilding system. Source removal, not masking, fixes it. Call (361) 326-5060 for an inspection.
Yes, if they’re connected to your main HVAC or have their own mini-split ducted components. Ignoring these creates a second dust and ash reservoir that recirculates into the main house through pressure differentials. We include outbuilding runs in our full-system assessment. Call (361) 326-5060 to discuss your property layout.
Arrival inside the quoted window, a written price before any work starts, protection of floors and furnishings, then HEPA-contained negative-air cleaning with rotary brush agitation. We camera-inspect key runs and show you before-and-after footage. The site is left clean, and you receive documentation of the 365-Day Done Right Promise. Most Sierra Madre homes take 3 – 5 hours. Call (361) 326-5060 to book.
Pre-1950s galvanized and early sheet-metal ducts are more fragile than modern flex duct. We adjust brush speed and vacuum pressure to avoid damaging seams or dislodging old mastic. Camera inspection is essential to identify prior repairs, disconnected sections, or asbestos-containing materials that require special handling. The goal is thorough cleaning without creating new problems. Call (361) 326-5060 and we’ll assess your specific system.
