Why Bellows Air Duct & Vent Co. Is Belmont’s Preferred Air Duct Cleaning Company
Belmont homeowners stay in their homes a long time. They remember the contractor who quoted one price and invoiced another. We don’t operate that way.

Our 90-Day Done Right Promise is stamped on every job. If the work isn’t right, we return at no charge with no paperwork required. That’s backed by our K.E.Y.S. values code and 42 years of meaning it.

We answer calls with a live person around the clock - not voicemail, not an app. Most Belmont appointments are scheduled within 24-48 hours, and emergency service is available when fog-season moisture has pushed your system past tolerable.
Our Air Duct Cleaning Services in Belmont
Residential Duct Cleaning
Belmont’s inventory of 1950s-1970s ranch homes, concentrated in the Carlmont neighborhood and the flatlands along El Camino Real, frequently contains original sheet-metal or early flex-duct systems that were never designed for modern airflow demands and have rarely been professionally cleaned. We use Rotobrush and Nikro equipment to agitate and extract built-up debris from these aging systems without damaging fragile connections. A typical residential duct cleaning in Belmont runs $380-$550 for a single-system home.
Commercial Duct Cleaning
Belmont’s commercial base - medical offices near Alameda de las Pulgas, retail along El Camino, professional services in the Ralston corridor - requires scheduled maintenance that doesn’t disrupt business hours. We coordinate after-hours and weekend service for commercial clients, with camera documentation for facility managers and property owners who need records for insurance or lease compliance. Commercial duct cleaning in Belmont typically starts at $650 and scales with system complexity.
Supply Duct Cleaning
Supply ducts push conditioned air into your living spaces, but in Belmont’s fog-belt climate, they’re also the pathway for marine-layer humidity when joints and boots have failed. We clean supply trunks and branch lines, then pressure-test for leaks that draw unfiltered air. Supply-only cleaning runs $280-$420 in most Belmont homes.
Return Duct Cleaning
Return ducts pull air back to your HVAC system, and in Belmont they’re particularly vulnerable. The hillside streets above Ralston Avenue experience slow soil creep on steep clay slopes, which over decades separates duct boots from registers - so homes quietly pull unfiltered, damp crawl-space air into living spaces, a failure mode rarely seen in flatter Peninsula towns like Redwood City. Our Air Duct Cleaning team inspects every return connection with a camera before cleaning, identifies separated boots, and reseals with mastic. Return duct cleaning in Belmont typically runs $240-$380, with repairs quoted separately and approved by you before we proceed.
Full System Cleaning
For homes with comprehensive buildup or suspected cross-contamination between supply and return sides, we recommend full system cleaning. This covers all ductwork, the air handler cabinet, and the blower assembly. In Belmont’s older housing stock with undersized original ducts, full system cleaning often reveals restrictions that have been forcing your HVAC to overwork for years. Full system cleaning in Belmont runs $550-$720.
Video Inspection
Every Bellows job includes video inspection before and after. In Belmont, this isn’t just documentation - it’s diagnostic. Our techs regularly find mold colonies in hillside crawl-space ducts that homeowners had no idea existed, separated boots pulling in fog-laden air, and corrosion at galvanized joints that will fail within seasons. The camera doesn’t lie, and we show you the footage. Standalone video inspection for Belmont homeowners who want a condition assessment without immediate cleaning runs $180-$240.

Trusted Brands We Service in Belmont
We clean and maintain ductwork connected to all major HVAC brands, and we specify professional-grade equipment from Honeywell, Aprilaire, and Abatement Technologies for filtration upgrades and sanitizing work. When a Belmont home needs a new filter cabinet or UV germicidal installation after cleaning, we stock Honeywell media filters and Aprilaire whole-home purifiers that match the capacity of Peninsula-sized systems. Parts are available without the long lead times that plague lesser-equipped operators, so most upgrades happen during the same visit.
Common Air Duct Cleaning Problems We See in Belmont Homes
- Salt-laden fog corrosion. The marine layer that rolls through Coast Range gaps carries corrosive salt particulates that attack galvanized ductwork at unsealed joints. We find pinhole leaks and rusted connections in homes within a mile of the bay, particularly in 1960s construction with original metal ducts. Camera inspection reveals the damage before it becomes a contamination pathway.
- Hillside boot separation. On a Twin Pines split-level, our techs found the return duct boot completely detached from the register, sucking in cold, moist crawl-space air laden with mildew spores - the result of decades of hillside movement. We resealed all duct connections with mastic, replaced the corroded galvanized boots, and installed a new Aprilaire filter, restoring proper airflow and indoor air quality for the family.
- Crawl-space mold colonization. High humidity in unconditioned hillside crawl spaces promotes mold growth inside ducts, often hidden from view but detectable during video inspection. Belmont’s wet winters compound this as Santa Cruz Mountain rainfall raises ground moisture that wicks into duct systems. We treat affected ducts with EPA-registered sanitizers and recommend sealing strategies to prevent recurrence.
- Undersized flex-duct deterioration. The post-WWII ranch homes in Carlmont and along El Camino Real frequently contain early flex-duct installations that have collapsed internally or disconnected at takeoffs, restricting airflow and creating pressure imbalances that draw unfiltered air. Our camera inspection identifies these restrictions without destructive access.

FAQs - Air Duct Cleaning in Belmont
Belmont homeowners typically need duct cleaning every 3-4 years rather than the standard 5-year interval, because marine-layer humidity accelerates mold growth and corrosion inside ductwork. The salt-laden fog that penetrates poorly sealed duct joints also deposits corrosive particulates that degrade metal components faster than in drier inland climates. If your home is in the hillside zones above Ralston Avenue or near the bay-edge flatlands, annual video inspection is worth considering. Call (844) 685-6342 to schedule - estimates are free.
Slow soil creep on steep clay slopes above Ralston Avenue gradually shifts crawl-space framing, pulling duct boots away from floor and wall registers over decades. This is a failure mode specific to Belmont’s hillside terrain and rarely seen in flatter Peninsula towns. Once separated, your HVAC system draws unfiltered, moisture-laden crawl-space air directly into living spaces. Our camera inspection identifies boot separation before it becomes a health issue, and we reseal with mastic and mechanical fasteners that accommodate future movement. Call (844) 685-6342 for an inspection - estimates are free.
Yes, we clean commercial ductwork for medical offices, retail, and professional services throughout Belmont, with after-hours and weekend scheduling to avoid business disruption. Commercial systems require documented pre- and post-cleaning camera inspection for lease compliance and insurance records, which we provide as standard. Typical commercial duct cleaning in Belmont starts at $650. Call (844) 685-6342 to discuss your facility’s schedule and requirements - estimates are free.
We use professional-grade Rotobrush and Nikro agitation and extraction equipment for cleaning, and specify Honeywell, Aprilaire, and Abatement Technologies for filtration upgrades and sanitizing systems. These are the same brands serious HVAC contractors specify, not discount-shop alternatives. When your Belmont home needs equipment replacement after cleaning, we stock compatible components for same-visit completion. Call (844) 685-6342 to discuss what your system needs - estimates are free.
Yes, video inspection is the most reliable non-destructive method to identify mold colonization inside ducts, particularly in Belmont’s hillside homes where crawl-space humidity creates hidden growth conditions. Our camera records high-resolution footage of interior duct surfaces, revealing discoloration, standing moisture, and organic buildup that indicates active biological contamination. Every Bellows cleaning job includes before-and-after video documentation; standalone inspection for concerned homeowners runs $180-$240. Call (844) 685-6342 to schedule - estimates are free.
