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 Oak Park’s Preferred Air Duct Cleaning Company
We’ve been in business since 2004 as part of the Garrison Partners family, and our reputation in Oak Park is built on showing up inside the window and leaving the site clean.

The Garrison Standard requires written prices, written guarantees, and the 365-Day Done Right Promise on every job. If our work fails within a year, we come back and make it right at no charge, including a free second visit. That’s not a slogan; it’s in writing on every invoice.
Air Duct Repair in Oak Park
Air Duct Repair in Oak Park addresses the cracked, crushed, and disconnected ductwork common in homes built from the 1960s through the 1990s. Original flex and rigid duct systems in Oak Park tract homes are prone to rodent intrusion, collapse at elbows, and separation at joints. When your system leaks, you’re paying to heat or cool your attic or crawl space, not your rooms. Typical Air Duct Repair in Oak Park runs $200 – $500 per section, with full system repairs ranging $800 – $1,800 depending on accessibility and material.
Camera Inspection Before Repair
We run a video inspection through every accessible duct before quoting repair work. In Oak Park, we regularly find original 1980s flex duct collapsed behind walls or chewed open by rodents in crawl spaces. The camera lets us show you exactly what we’re talking about, so the price we write down is based on facts, not guesses.
Sealing With Mastic and Mechanical Fasteners
We don’t use duct tape for permanent repairs; it fails. Our crews seal joints and patches with mastic compound and mechanical fasteners, then test for leakage. On a recent job near Oak Park’s Medea Valley area, we dropped the measured leakage from 28% to under 4%, which the homeowner saw on the blower-door readout before we packed up.
Ductwork Cleaning in Oak Park
Ductwork Cleaning in Oak Park removes the accumulated ash, pollen, dust, and debris that settles into HVAC systems through fall and winter. Because Oak Park sits downwind of the Conejo Valley and adjacent to wildfire-prone terrain, Santa Ana wind events push fine particulate straight into return ducts and air handlers. A typical full-system Ductwork Cleaning in Oak Park runs $350 – $650 for residential properties, with commercial systems starting around $800.
Negative-Air Method With HEPA Filtration
We use Nikro negative-air machines to pull debris out of your ducts under controlled suction, exhausting through HEPA filtration so nothing settles back into your home. This matters in Oak Park, where wildfire ash particles are fine enough to pass through standard filters and recirculate if the extraction isn’t contained.
Rotobrush Agitation for Supply and Return Lines
Our Rotobrush rotary brush systems scrub the interior duct walls where vacuum suction alone won’t reach. On older Oak Park systems with decades of buildup, we run the brush through every supply and return line, then verify cleanliness with a follow-up camera pass. You see the before and after on the same screen.
Trusted Brands We Service in Oak Park
We clean and service duct systems connected to all major HVAC brands, and we stock filtration products from Honeywell, Aprilaire, and Guardsman for Oak Park customers who need replacement media after a cleaning. Our equipment roster includes Nikro negative-air machines and Rotobrush rotary systems, the same tools commercial crews use in hospitals and schools. If your Oak Park home runs a Honeywell electronic air cleaner or an Aprilaire whole-house humidifier integrated with the duct system, we know how to remove, clean, and reinstall those components without breaking the seal. Fast turnaround on filter media means you’re not running a bypassed system while waiting for parts.
Common Air Duct Cleaning Problems We See in Oak Park Homes
- Wildfire ash coating return ducts after Santa Ana wind events. Oak Park’s position at the mouth of the canyons means fine ash and soot get drawn into return grilles almost every fall. Homeowners often don’t notice until the following spring, by which point the debris has redistributed through the supply side.
- Original 1960s – 1990s flex duct collapsing at elbows and joints. The tract-home stock in Oak Park includes miles of original flex and rigid duct that has never been properly cleaned. These systems leak, sag, and trap debris where homeowners can’t see it.
- Rodent intrusion in crawl space and attic duct runs. Oak Park’s semi-rural interface with open land means mice and rats find their way into duct systems, leaving nesting debris, droppings, and chewed openings that compromise both air quality and system efficiency.
- Outbuilding and detached-garage HVAC systems pulling dust from unpaved drives. Larger Oak Park properties often have shop or garage systems connected to the main house returns. These pull dust from unpaved surfaces and blow it through the whole home until they’re included in the cleaning scope.

FAQs About Air Duct Cleaning in Oak Park
Most Oak Park homes near the canyons need duct cleaning every 18 – 24 months, not annually, because the Santa Ana wind loading is seasonal and concentrated. After a significant wildfire event within 20 miles, we recommend inspection even if you’re inside that interval. Call (361) 326-5060 and we’ll check your filter and register condition over the phone to help you time it.
If you smell smoke or see ash settling on outdoor surfaces, you should at least inspect your return grilles and change your filter. Fine ash passes through standard filters and coats the air handler and supply ducts. We offer post-wind-event inspections in Oak Park for a flat fee that applies toward cleaning if needed.
Original 1970s ductwork in Oak Park is often worth repairing if the trunk lines are rigid metal and only the flex branches are failing. We camera-inspect first. If the system is more than 50% compromised, we’ll tell you straight and help you compare repair cost against replacement. The 365-Day Done Right Promise covers our repair work for a full year.
We recommend MERV 11 – 13 for Oak Park homes with canyon exposure, but only if your air handler can handle the static pressure. Higher MERV filters load faster with ash and pollen, so they need more frequent changes. During Santa Ana wind season, check your filter monthly. We stock Honeywell and Aprilaire media and can verify your system’s pressure drop on any service call.
Yes. We clean ductwork and air handlers in detached structures on larger Oak Park properties, and we inspect whether those systems are cross-connected to your main house returns. Outbuilding systems often pull dust from unpaved drives and introduce it to the whole home. We price these as separate systems and include them in the written scope before starting.
