Our dispatch office coordinates crews from Miami, and we serve South Pasadena homeowners with the same standards we’ve held for 42 years: background-checked, uniformed technicians; upfront pricing before any tool is lifted; and our 90-Day Done Right Promise in writing. No bait coupons. No price changes at the door.

Why Bellows Air Duct & Vent Co. Is South Pasadena’s Preferred Air Duct Cleaning Company

We’ve built our reputation on never needing to be called back. In South Pasadena, that matters more than most places - because retrofit ductwork in a 1923 Spanish Colonial Revival isn’t something you learn from a manual. You learn it by crawling through low-clearance spaces, identifying asbestos wrap before you agitate it, and knowing when a flex duct has pulled loose from its register because the original lath-and-plaster wall couldn’t hold a proper mounting bracket.

Our technicians answer to a live person at the office, 24 hours a day. Not a voicemail. Not an app. When you call (844) 685-6342, someone picks up. That’s how we’ve operated since Ray Castillo founded this company in 1984.

Every job gets a camera inspection before and after. You see what we see - the dust buildup, the insulation migration, the rodent evidence. No claims without proof. Our 90-Day Done Right Promise means if anything’s not right, we return at no charge. No paperwork, no arguing.

We offer a permanent 5% Senior and Veteran discount, a $89 Seasonal Tune-Up, and $50 off any repair over $250. And if you’ve got a written estimate from another company, we’ll give you a free second opinion.

Our Air Duct Cleaning Services in South Pasadena

Residential Duct Cleaning

Most South Pasadena homes weren’t built for central air. The Craftsman bungalows on Bank Street, the Spanish Colonial Revivals near Garfield Park, the Victorians along Mission Street - all constructed before ductwork existed. When HVAC arrived in the 1960s-1980s, installers ran flex duct through crawl spaces and attics never designed for it. Our residential cleaning accounts for this: we use compact Rotobrush equipment that maneuvers in tight retrofitted spaces, and we never force a brush through a run we haven’t first inspected with a camera.

Commercial Duct Cleaning

South Pasadena’s commercial buildings along Fair Oaks Avenue and Huntington Drive include historic structures with their own retrofit challenges. We clean ductwork in restaurants, medical offices, and retail spaces with minimal disruption to business hours. Our Abatement Technologies HEPA vacuums contain debris during cleaning, and we schedule around your operations - early mornings, evenings, or weekends.

Supply Duct Cleaning

Supply ducts carry conditioned air to your rooms. In South Pasadena’s historic homes, these runs often travel through unconditioned crawl spaces where Santa Ana winds deposit fine desert dust and wildfire particulates. Our crew recently cleaned the supply ducts in a 1924 Craftsman bungalow near the 110 Arroyo Seco Parkway. The flex ducts, retrofitted in the 1970s, had pulled loose from the registers in the low crawl space, and we used our Rotobrush system to clear years of fine Santa Ana dust and a few rodent droppings. We re-secured the connections and video-inspected the run to confirm airflow to every room.

Return Duct Cleaning

Return ducts pull air back to your HVAC system. In South Pasadena, these are particularly vulnerable to insulation migration - aging blown-in insulation in attics works its way into duct joints, partially blocking airflow. Without video inspection before and after cleaning, crews can miss these blockages entirely. We don’t. Our camera shows you the restriction, and our cleaning removes it.

Full System Cleaning

A full system cleaning addresses supply ducts, return ducts, the air handler, and registers. For South Pasadena’s historic homes, this is often the right choice - retrofit systems accumulate debris at multiple points, and partial cleaning can leave contaminated sections recontaminating clean ones. We price full system cleaning upfront, and most jobs finish in one visit.

Video Inspection

Every Bellows job includes video inspection. In South Pasadena, this isn’t optional - it’s essential. Historic homes may contain asbestos-containing duct wrap from 1960s-70s retrofits. We inspect for deteriorating wrap before agitating any dust, and we follow South Coast AQMD asbestos disturbance notification requirements. Video inspection also confirms we’ve reached every duct run in irregularly routed systems, and it gives you a visual record of the work.

Trusted Brands We Service in South Pasadena

We clean and service ductwork connected to all major HVAC brands, and we use professional-grade equipment ourselves: Rotobrush brush systems for mechanical agitation in tight spaces, Abatement Technologies HEPA containment vacuums, and Aprilaire media air cleaners when upgrades make sense. For South Pasadena homeowners, this means we can source replacement components without long waits - we carry common fittings, flex duct, and register boots on our trucks. If your system needs more than cleaning, we’ll tell you straight, show you the video, and quote the repair before any additional work.

Common Air Duct Cleaning Problems We See in South Pasadena Homes

• Cramped crawl space access. Retrofitted ducts in historic crawl spaces often have severely restricted access, making cleaning equipment difficult to maneuver and requiring technicians to work in tight, uncomfortable positions. Rushed crews do partial cleans. We take the time to do it right, even when that means repositioning equipment multiple times.
• Asbestos-containing duct wrap. Many 1960s-70s retrofits used duct wrap with asbestos. If technicians don’t inspect for deteriorating wrap and follow South Coast AQMD notification rules before agitating dust, they risk releasing fibers. This is a compliance failure that can halt the job - and a genuine liability in South Pasadena’s historic corridors. We check first, every time.
• Insulation migration. Aging blown-in insulation in attics easily works its way into duct joints, and without proper video inspection before and after, cleaning crews can miss these blockages, leaving supply runs partially restricted. Our camera finds what brushing alone cannot.
• Santa Ana dust accumulation. South Pasadena sits in the San Gabriel Valley bowl, where Santa Ana wind events seasonally drive desert dust, wildfire smoke particulates, and combustion debris directly into home duct systems. Homes near the 110 Arroyo Seco Parkway and 210 Freeway accumulate ultrafine exhaust particulates at rates higher than more freeway-insulated communities. Cleaning intervals here should reflect that exposure.
