Fast, Reliable Air Duct Cleaning Across Highland Park
Air duct cleaning in Highland Park typically runs $450 – $900 for a full system on a single-family home, and most jobs are finished in four to six hours. That’s the number homeowners off York Boulevard and up in the hills ask us about most. We know the difference between a 1910 Craftsman near Figueroa and a hillside Spanish Revival above Avenue 50, because our crews work both every week. If you want a written price before anyone touches your ducts, call us at (626) 469-5477.
Why Hollis Air Duct Pasadena Is Highland Park’s Preferred Air Duct Cleaning Company
The Garrison Standard is what sets us apart from the coupon outfits that run ads in Highland Park. It means the price is written down before we start, the crew arrives inside the window we quoted, and the job is done by the book or we come back. Roy Castellanos runs our operation with one rule: no moving targets. Highland Park homeowners tell us the same thing again and again. They got burned by a low teaser price that doubled once the van was parked out front. That doesn’t happen here. The price we write is the price you pay, and every job carries a 365-Day Done Right Promise in writing.
Our technicians are background-checked and uniformed. When they pull up to a narrow hillside street above York Boulevard, they know how to park without blocking a neighbor’s driveway. That matters in Highland Park, where permit parking and tight switchbacks can turn a simple job into a neighborhood dispute. We’ve serviced enough pre-1950s bungalows and hillside homes here to know what’s inside the ductwork before we open it. And if you call at 2 a.m. with a question, a live person answers. No voicemail loop.

Air Duct Repair in Highland Park
Air Duct Repair in Highland Park usually means fixing the undersized, original sheet-metal ductwork in pre-1950s Craftsman and Spanish Colonial Revival homes. The first sentence you need to know is this: air duct repair in Highland Park runs $350 – $1,100 depending on the length of duct being replaced or sealed, and it’s often the difference between a clean system that still underperforms and one that actually pushes air to the back bedrooms.
Source Removal and Repair Scope
When we open a return in an Avenue 50 hillside house, we commonly find rusted sheet metal seams pulling apart at the joints. That lets attic dust and fiberglass insulation get pulled into the airflow. Repair here means resealing those joints with duct mastic, not duct tape. Duct mastic is a brush-on sealant that hardens and stays airtight, unlike tape that dries out and peels in a hot attic. We also repair crushed or disconnected runs caused by decades of homeowners storing boxes in crawlspaces.
When Repair Beats Cleaning
Cleaning alone won’t fix airflow if the duct itself is collapsed or the return is undersized for the square footage. Our crews find that often in 1920s cottages where a modern furnace was retrofitted onto original ducts built for a floor furnace. We camera-inspect before recommending repair. You see the images, we show you the problem, and the price is written before we touch anything.
Ductwork Cleaning in Highland Park
Ductwork cleaning in Highland Park homes means removing the fine silt, pet hair, and decades of accumulated dust from supply and return ducts, using negative-air machines and rotary brush agitation. Homeowners in Highland Park should expect to pay $400 – $800 for a full system cleaning on a typical two-to-three-bedroom bungalow. Larger hillside homes with extensive runs or multiple returns will push toward the higher end.
Negative-Air Cleaning Method
We use a Nikro or Abatement Technologies negative-air machine to create suction on the duct system while Rotobrush agitation tools knock debris loose from the walls. The negative pressure keeps dust from blowing back into your living room during the job. That’s the standard commercial crews use, and it’s the standard we bring to every house in Highland Park. We also deploy HEPA filtration on the machine’s exhaust. Fine particulate from the 110 freeway and Arroyo Seco winds settles deep in ducts. HEPA captures it instead of recirculating it through the home.
Video Inspection Before and After
Every ductwork cleaning in Highland Park includes a camera inspection of the main trunk line and key branch runs before we start. That lets us spot asbestos-wrapped ducts that should not be agitated, or collapsed sections that need repair before cleaning can do any good. After the work is done, we run the camera again. You’ll see before-and-after images of your own ducts, not stock photos. That’s how you know the work was actually done.
Trusted Brands We Service in Highland Park
We built our equipment roster around the brands commercial contractors trust: Rotobrush rotary brush systems, Nikro negative-air machines, and filtration products from Abatement Technologies, Honeywell, Aprilaire, and Guardsman. The Aprilaire and Honeywell media filters we install are sized to fit the existing filter housings in most Highland Park homes, including older models still running on one-inch filter slots. That means no custom fabrication delays. We keep Guardsman and Aprilaire replacement media in trucks serving Highland Park so a filter swap happens the same day if your system calls for it.

AfterCommon Air Duct Cleaning Problems We See in Highland Park Homes
- Wind-blown debris in hillside returns: Homes on exposed slopes above York Boulevard, especially those ascending from Avenue 50 toward Mount Washington, pull in significantly more dust and leaf litter through east-facing return grilles. The Arroyo Seco corridor funnels wind directly into those returns, so filters clog faster and ducts fill with fine silt.
- Original undersized sheet-metal ducts: Many pre-1950s Craftsman and bungalow homes in Highland Park still run on their original galvanized ductwork, sized for floor furnaces and never resized for modern forced-air systems. The result is high static pressure, noisy airflow, and rooms that never quite reach the thermostat setpoint.
- Asbestos-wrapped ducts on pre-1950s homes: We regularly encounter older ductwork wrapped in asbestos-containing insulation in Highland Park’s earliest housing stock. Our crews camera-inspect first and never agitate suspect material. Disturbing friable asbestos during a careless cleaning creates a serious health hazard.
- Shared stack ducts in multi-family courts: Highland Park’s bungalow courts and converted Craftsman multi-family buildings often share vertical duct stacks between units. Cleaning one unit without addressing the shared stack leaves the job incomplete. We coordinate with landlords and HOAs so the entire run gets done in one visit.

FAQs About Air Duct Cleaning in Highland Park
Every two to three years is the realistic interval for a pre-1950s bungalow near the 110 freeway, because the freeway dust and Santa Ana winds load your ducts faster than a house in a quiet cul-de-sac. Hillside homes with east-facing returns may need inspection more often, as debris accumulates quickly on exposed slopes. Call (626) 469-5477 for an exact quote based on your system; estimates are free.
Yes, and the shared stack is exactly why individual unit cleaning alone often fails. Air moves through common vertical stacks that serve multiple units, so cleaning just one apartment leaves years of dust in the shared trunk that will re-enter your space. We coordinate with landlords and HOAs to clean the shared stack and the unit together, which is the only way to get a real result.
Cleaning improves airflow only if the ducts are intact and the sizing is adequate for your furnace’s output. Original undersized ducts in Craftsman homes simply cannot move enough air for modern systems, no matter how clean they are. We camera-inspect first, then give you a written recommendation. If repair or sealing is needed, the price is on the table before any work starts.
Yes, because the vent run is longer, often shared through a stack, and more difficult to access. Stacked multi-family dryer vents require specialized rotary brush equipment and sometimes roof or roof-access work, which we schedule in advance with the property owner. Clearing these runs properly prevents lint buildup that creates a fire hazard in shared walls. Call us for a written quote; we’ll inspect the run first and explain what’s involved.
Watch for a fine gray dust settling on furniture within days of cleaning, filters darkening within two weeks, and a noticeable dry earthy smell when the system kicks on. Homes on the east-facing slopes above York Boulevard pull wind-blown silt from the Arroyo Seco corridor directly into their returns. If you’re seeing these signs, the return side of your system needs a camera inspection. Call (626) 469-5477 and we’ll take a look.
