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 Air Duct Cleaning Across Broadmoor
Air duct cleaning in Broadmoor typically runs $350 – $650 for a full residential system and is usually scheduled within a few business days. Our crews work the San Mateo County corridor regularly, so Broadmoor homes near Skyline Boulevard or tucked off John Daly Boulevard aren’t waiting weeks for an appointment.
We’re familiar with the tight lots and mid-century layouts that define this unincorporated pocket. Many Broadmoor houses were built in the 1940s and 1950s with ductwork sized for smaller furnaces and minimal filtration. That original metal or early flexible ductwork, often partially buried in crawlspaces or slab configurations, collects decades of debris that modern systems simply weren’t designed to handle. When our Air Duct Cleaning team arrives, we’re not guessing at what we’ll find. We’ve worked these floor plans before.
Scheduling and dispatch are coordinated from our Los Angeles office, but the crew that pulls up to your Broadmoor curb is local to the Bay Area. They know the fog layer rolls in thick off the coast, they know which streets dead-end into the hillside, and they know that damp marine air here means mold and mildew inside ducts are bigger concerns than dust from a heavy heating season. Call (361) 326-5060 and you’ll reach a live person, any time of day.
Why Hollis Air Duct Cleaning Is Broadmoor’s Preferred Air Duct Cleaning Company
Broadmoor residents have a specific set of frustrations with home service companies: no-shows, crews who track grime through the house, and prices that mysteriously climb once the van is in the driveway. We’ve built our operation to eliminate each of those. Every Hollis technician is background-checked and uniformed, and every job starts with a written price that does not move.
Our reputation in San Mateo County rests on The Garrison Standard, which means arriving inside the quoted window, pricing in writing before any equipment touches your system, completing the work by the book, and leaving the site clean. Roy Castellanos leads this operation, and that standard applies to every Air Duct Cleaning in Broadmoor we perform.
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 morning to get on the schedule.
The 365-Day Done Right Promise backs 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. That guarantee is not common in this trade, and we put it in writing on every Broadmoor invoice.
Commercial Air Duct Cleaning in Broadmoor
Commercial Air Duct Cleaning in Broadmoor covers the small multi-unit buildings, duplexes, and professional offices that share this dense, unincorporated territory with single-family homes. These systems often serve multiple tenants from a single rooftop or basement unit, and the ductwork runs through shared walls and tight mechanical closets that require careful coordination. A typical commercial duct cleaning in Broadmoor runs $800 – $1,800 depending on system size and accessibility.
Multi-Unit Building Coordination
We schedule around tenant hours and building access protocols, cleaning supply and return lines without disrupting neighboring units. Our Nikro negative-air machines contain debris at the source, so dust doesn’t migrate through shared vents during the job.
Post-Cleaning Documentation
Property managers receive before-and-after photos of their own ductwork, not stock images. This documentation supports maintenance records and gives you proof the work was performed to standard.
Air Duct Cleaning Services in Broadmoor
Air Duct Cleaning Services in Broadmoor address the specific challenges of mid-century housing stock in a cool, foggy coastal environment. A typical full residential system cleaning here runs $350 – $650, with video inspection, supply duct cleaning, and return duct cleaning available as standalone or bundled options. The damp marine air that keeps Broadmoor mild year-round also promotes mold, mildew, and dust-mite proliferation inside ducts that were never designed for modern filtration loads.
Video Inspection and Documentation
We feed a camera through your duct runs before any cleaning begins, so you see exactly what we’re dealing with. In Broadmoor’s older homes with cramped, partially buried ductwork, this step often reveals blockages or deterioration that a surface check would miss.

Supply and Return Line Cleaning
Supply ducts push conditioned air into your rooms; return ducts pull it back. Both sides need attention, but the returns near floor level in Broadmoor homes often collect the most debris, especially fine road dust and black carbon from the nearby I-280 corridor. Our Rotobrush rotary brush system agitates this buildup while negative-air extraction removes it completely.

Trusted Brands We Service in Broadmoor
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines for contained debris removal, and filtration products from Honeywell, Aprilaire, and Guardsman for homeowners who want to upgrade after cleaning. We stock common parts and replacement filters for these brands, so Broadmoor customers aren’t waiting on shipping from a distant warehouse. When a technician recommends a filtration upgrade following your duct cleaning, the hardware is typically available for same-visit installation. This matters in a market where many competitors run lean on inventory and return trips stretch across multiple weeks.
Common Air Duct Cleaning Problems We See in Broadmoor Homes
- Mold and mildew in damp coastal ductwork. Broadmoor’s foggy, mild climate means ducts rarely dry out completely. We regularly find active mold growth on the interior of return plenums and flex duct, especially in homes with slab foundations where groundwater moisture wicks upward.
- Fine carbon and road dust near I-280. Homes within earshot of the Skyline Boulevard corridor pull measurable black particulate into return registers. This isn’t ordinary household dust; it’s combustion residue that standard filters weren’t designed to capture and that accumulates in layers on duct walls.
- Restricted airflow in original mid-century metal duct. The 1940s – 1950s rigid metal ductwork common in Broadmoor was sized for smaller furnaces with lower static pressure. Decades of debris buildup, plus modern HVAC upgrades that push more air, create bottlenecks that show up as weak airflow at distant registers.
- Collapsed or deteriorated early flexible duct. Some Broadmoor homes have partial flexible duct installations from later retrofits. These materials degrade faster in damp crawlspaces, and we find collapsed runs that effectively dead-end airflow to entire rooms.
Pricing for Air Duct Cleaning in Broadmoor, CA
Full residential air duct cleaning in Broadmoor typically costs $350 – $650 for a complete system, including supply and return lines, main trunk, and register cleaning. Video inspection alone runs $150 – $250. Dryer vent cleaning, which we often pair with duct work, adds $120 – $180. Commercial systems in Broadmoor’s small multi-unit buildings start around $800 and range to $1,800 for larger or more complex layouts.
What moves the price: system size, accessibility of duct runs, and the condition we find inside. A home with original mid-century metal duct in a tight crawlspace takes longer than one with modern, accessible flex lines. We inspect first, write the price down, and get your approval before any cleaning begins. That price does not change at the door. No per-vent add-ons, no equipment fees that appear mid-job. Call (361) 326-5060 for a free estimate and we’ll give you a firm range before we schedule.

FAQs About Air Duct Cleaning in Broadmoor
We typically schedule Broadmoor appointments within 2 – 4 business days, and sometimes sooner depending on current demand. Because our crews already work the San Mateo County corridor, travel time to Broadmoor is built into our routing, not added as a delay. Call (361) 326-5060 to check next available slots.
We cover all of Broadmoor’s unincorporated territory, including homes near Skyline Boulevard, the compact streets off John Daly Boulevard, and the hillside pockets above the I-280 corridor. There is no zone within Broadmoor that we decline.
We do not classify duct cleaning as an emergency service, but our phones are answered by a live person 24/7 and we can often accommodate urgent scheduling for situations like post-renovation dust contamination or visible mold discovery. For true HVAC emergencies like complete system failure, we recommend contacting your heating and cooling contractor first, then scheduling duct cleaning once mechanical function is restored.
Broadmoor pricing falls in line with San Mateo County generally, though the tight lots and older access configurations here can add modest labor time compared to newer tract homes in Daly City or South San Francisco. We account for this during our free pre-work inspection, and the written price you receive reflects your specific home, not a generic regional rate.
Every duct cleaning job in Broadmoor is covered for one full year from the invoice date. If airflow issues return, if mold recurs in cleaned ductwork, or if any aspect of our work fails, we return and make it right at no charge, including a free second visit if needed. This is written on every Hollis invoice, not implied or verbal. Call (361) 326-5060 with any concern during that year and we’ll schedule the return trip.
