We’ve been driving the same Van Nuys streets for over 42 years - from the post-war ranches along Laurel Canyon Boulevard to the garden-apartment complexes near Strathern Playground, out toward the Sepulveda Dam Recreation Area and up through the 91411 and 91410 ZIP codes. We know which homes were built with original sheet-metal trunk lines and which flex-duct systems are failing in 140°F attics. That local knowledge changes what equipment we bring and what problems we expect to find before we even ring your doorbell.

Why Bellows Air Duct & Vent Co. Is Van Nuys’s Preferred Air Quality & Sanitizing Company

Ray Castillo built this company in 1984 on a simple standard: one honest price shown before work starts, and a 90-Day Done Right Promise backed in writing with no paperwork and no arguing. Van Nuys homeowners have been calling us back for decades because that standard never changed.

Our reputation here is word-of-mouth in neighborhoods where people stay put for twenty, thirty years. We’ve cleaned ducts in the same Valley Glen and Sherman Oaks homes three times over as families raised kids and grandkids. Reviews from Van Nuys customers consistently mention the camera inspection - seeing the before-and-after footage themselves, not taking our word for it.

Response time matters in Van Nuys heat. When your AC has been cycling wildfire smoke and Valley dust through the system for weeks, you don’t want an appointment window next Tuesday. Our technicians answer to a live person at the office 24 hours a day, and most Van Nuys calls dispatch same-day.

We also understand the local housing stock in a way that matters for sanitizing. A 1960s Panorama City apartment complex with shared horizontal duct runs through unconditioned attics needs negative-pressure cleaning, not a brush-and-blow. A 1970s stucco ranch near Our Lady of Peace with separated flex-duct joints needs joint sealing before any sanitizer goes in. We don’t guess. We inspect with cameras first.

Our Air Quality & Sanitizing Services in Van Nuys

Odor Removal

Van Nuys homes trap odors that coastal properties simply don’t face. Wildfire smoke from the Santa Susana and Verdugo hills pools in the Valley floor during temperature inversions, and that smoke residue embeds in duct linings, cycling through your vents every time the compressor kicks on. We treat odor at the source with enzyme-based breakdown agents and thermal fogging for severe cases, not masking sprays that wash out in a week. For persistent smoke odor in ductwork, a typical Van Nuys odor removal treatment runs $320-$480.

Allergen Reduction

The alluvial dust from the LA River channel and Sepulveda Dam flats is fine-grained and mineral-heavy, different from ordinary household dust. Santa Ana winds drive it directly into return-air grilles, and our technicians report some of the heaviest return-side buildups anywhere in Los Angeles County. We deploy HEPA-contained negative-pressure systems to extract this debris without redistributing it, followed by anti-allergen treatment. A whole-home allergen reduction service in Van Nuys typically costs $350-$580 depending on system size and contamination level.

UV Light Installation

Van Nuys’s combination of extreme heat, continuous AC runtime, and high particulate loads creates ideal conditions for microbial growth on evaporator coils and in drain pans. A UV-C light system installed at the coil kills mold and bacteria before they colonize, and in this climate, that prevention pays for itself. We specify Honeywell UV systems for Van Nuys installations - the same brand serious HVAC contractors use - with typical installation running $450-$720 including mounting and electrical connection. Your coastal cousin in Santa Monica doesn’t need this. You do.

Mold Treatment & Bacteria Sanitizing

When we camera-inspect Van Nuys ductwork, we regularly find mold in the cool, damp sections downstream from evaporator coils, especially in homes where flex-duct jacketing has degraded and pulled humid attic air into the supply stream. Our mold treatment uses EPA-registered fungicides applied with controlled misting equipment, followed by air-scrubber clearance testing. Bacteria sanitizing addresses the musty, sour smells that develop in systems running 18 hours a day through Valley summer. Combined mold and bacteria treatment in Van Nuys runs $380-$620.

Air Purifier Installation

For homes with chronic particulate issues - especially near Van Nuys Airport or the industrial corridors along Van Nuys Boulevard - whole-home air purifiers with MERV 13+ filtration or electronic precipitation capture what your standard filter misses. We size these to your existing air handler and install with no modification to ductwork in most cases. Typical Van Nuys installation: $680-$1,100.

Trusted Brands We Service in Van Nuys

We carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies - the same brands specified by serious HVAC contractors, not the consumer-grade units sold at big-box stores. For UV and purification work, we install Honeywell and Aprilaire systems with local warranty support. We stock replacement lamps, filters, and parts at our Los Angeles warehouse, so Van Nuys customers aren’t waiting two weeks for a specialty order when a UV bulb burns out or a HEPA cartridge needs changing. Most replacement parts are on our truck already.

Common Air Quality & Sanitizing Problems We See in Van Nuys Homes

• Flex-duct joint separations in 140°F attics. The extreme Valley heat degrades mastic adhesives and flex-duct jacketing in post-WWII ranches, pulling attic dust, insulation fragments, and rodent debris directly into your supply air. We camera-locate every separation before sealing.
• Heavy alluvial dust loading from Santa Ana winds. Fine mineral dust from the LA River channel and Sepulveda Dam sandy flats coats return-air grilles and duct interiors. Our crews recently treated a 1950s ranch home on Burbank Boulevard near Sepulveda Dam Recreation Area where years of this wind-driven dust had caked the entire return system. We deployed Rotobrush scrubbing and a Honeywell UV light system, cutting airborne particulate counts by two-thirds.
• Shared horizontal duct runs in 1960s apartment complexes. In Panorama City and North Hills East garden apartments, a single contaminated trunk line pushes debris into multiple units simultaneously. These buildings need full-system negative-pressure cleaning with contained extraction, not surface brushing.
• Wildfire smoke residue cycling through continuous AC operation. Van Nuys systems run five or more months straight, embedding smoke particulate deep in duct linings. Standard cleaning won’t touch it; thermal fogging and enzyme treatment are required.
