Air Duct Cleaning Company in Sylmar, CA
Air duct cleaning in Sylmar is a different job than it is a few miles south. The homes here sit against the San Gabriel Mountains, and when the Santa Ana winds come through the passes, they push fine mountain dust and ash into attics, returns, and supply runs. We’re Hollis Air Duct Cleaning, and we work on Sylmar’s mid-century single-family homes, hillside properties, and newer developments with one clear standard: the price is written down before we touch a register, and the work is covered by the 365-Day Done Right Promise. If the job isn’t done right within a year, we return and make it right at no charge. Call (661) 523-0295 for a free estimate.
Why Sylmar Homes Are Different
Sylmar is the northernmost neighborhood of Los Angeles, backed up against the San Gabriel Mountains. That geography shapes what collects inside the ductwork. During Santa Ana wind events, fine particulate from the hills and wildfire-prone areas channels into homes at a rate you won’t see in coastal parts of the city. After a strong blow, plenty of Sylmar homeowners watch a visible plume of dust lift off their supply registers the first time the system fires up. That’s not a filter problem. It’s the ducts.
The housing stock adds another layer. Much of Sylmar was built between the 1950s and 1970s, and those original homes often still run on metal ductwork that was sealed decades ago with materials that have since dried and separated. Joints leak. Returns pull air from attics that hold decades of dust. And some of these older systems have asbestos-containing duct insulation from that era, which demands careful handling rather than aggressive brushing. When we schedule a Sylmar job, we plan around the home’s age and construction, not just the square footage.
Styles & brands we work with
Our Main Sylmar Services
Most Sylmar homeowners call us about one of three things: the air ducts that need cleaning, the dryer vent that’s clogging, or the leaky duct joints that should have been sealed correctly the first time. Each service has its own Sylmar page with local pricing and details.
Air Duct Cleaning in Sylmar
Sylmar’s Santa Ana season fills ductwork with a fine silt that standard furnace filters can’t stop. We use the negative-air method: a Nikro machine pulls a vacuum on the entire system while a Rotobrush rotary brush loosens the packed dust from the duct walls, so debris leaves the house instead of relocating into your living room. For older Sylmar homes with original metal runs, we inspect for asbestos-containing insulation before we start and adjust the process accordingly. Two to three hours of focused work, and the system moves air the way it was built to. Read the full breakdown on our Air Duct Cleaning in Sylmar page.
Dryer Vent Cleaning in Sylmar
Clogged dryer vents are a slow-building hazard, and Sylmar’s dry, lint-heavy air makes the accumulation happen faster. We remove the packed lint from the full run, from the dryer to the exterior termination, and we check the outside vent cover while we’re there. If your dryer has been taking longer to finish a load or the outdoor flap barely moves when it’s running, the vent is telling you something. See pricing and timing on the Dryer Vent Cleaning in Sylmar page.
Duct Sealing in Sylmar
Leaky ducts are the quiet reason some Sylmar rooms never cool properly in the summer heat and heating bills run higher in the winter. We use duct sealing mastic, a thick, brushable compound that hardens and closes the gaps at joints and connections, which is exactly what the trade standard calls for rather than unreliable tape. For mid-century homes where the original seals have failed, sealing makes a measurable difference in airflow and indoor dust. The Duct Sealing in Sylmar page covers what we inspect and how we quote it.

What moves a Sylmar price toward the top of those ranges is access and condition: two-story hillside homes, original metal ductwork that hasn’t been serviced in years, or systems with multiple returns spread across an addition. What doesn’t move the price is the technician’s mood on the day of the job. You get the number in writing before work starts, and that number does not change at the door.
