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.

AfterAir Duct Cleaning Company in South Pasadena, CA
Air duct cleaning in South Pasadena runs $350 – $650 for most whole-home systems, with historic homes often landing higher due to access challenges. We’re Hollis Air Duct Cleaning, and we’ve built our work here around a reality most competitors underestimate: South Pasadena’s pre-1930s housing stock demands techniques closer to historic restoration than standard maintenance. Our crews use Rotobrush rotary systems and Nikro negative-air machines with the patience these old systems require, and every job starts with a written price that doesn’t move. Call (361) 326-5060 for a free estimate.
Why South Pasadena Homes Are Different
South Pasadena’s housing stock is dominated by 1900 – 1930 Craftsman bungalows and Spanish Colonial Revival homes, many still running on original unlined galvanized steel ductwork or gravity furnace retrofits that were never designed for modern forced air. These systems sit in low-clearance attics and crawlspaces with no access panels, so we often cut new openings and reseal them to match original plaster lines.
The Mediterranean climate here works against these aging systems. Hot, dry summers pull dust and foothill debris through every gap; mild, damp winters let humidity settle into ducts that lack modern sealing. Mature camphor and oak trees along streets like Mission and Orange Grove drop material year-round that finds its way indoors.
Then there’s the hazard most homeowners don’t see coming. We’ve found original 1920s ductwork wrapped in asbestos in historic districts near Meridian Avenue and Bank Street. That requires abatement certification and careful disposal, turning what looks like a routine cleaning into a specialized job. Local code also mandates lead-safe practices for any painted surface disturbance in pre-1978 homes. We carry both certifications and the containment equipment to work without damaging original walls or finishes.
Our Main South Pasadena Services
Homeowners in South Pasadena call us for three jobs, each with its own page and pricing below.
Air Duct Cleaning in South Pasadena
We clean supply and return ductwork with rotary brush agitation and negative-air extraction, the combination that pulls settled debris from galvanized steel without damaging thin vintage walls. In South Pasadena, we regularly encounter systems retrofitted into attics with 24-inch clearance or less, requiring smaller-diameter tools and hand-finishing near plaster junctions.

Dryer Vent Cleaning in South Pasadena
Dryer vents in older South Pasadena homes often run through exterior walls with original stucco or through long horizontal runs under the house, creating lint traps that standard brushes can’t clear. We use flexible rotary whips and camera inspection to verify flow restoration, critical in neighborhoods where original vent routing predates modern code. Dryer Vent Cleaning in South Pasadena
Duct Sealing in South Pasadena
Sealing is where South Pasadena homes see the clearest return. Unlined galvanized ducts from the 1920s leak 20 – 40% of conditioned air into attics and wall cavities. We apply mastic sealant and mechanical fasteners at joints, then pressure-test to verify improvement, often cutting summer cooling loads significantly in homes that were never designed for central air.

FAQs About Air Duct Cleaning Company in South Pasadena
No permit is required for standard cleaning, but if we cut new access panels in walls or disturb painted surfaces in pre-1978 homes, lead-safe practices are mandated by local code. We handle that compliance as part of the job, included in the written price.
Most South Pasadena homeowners get an appointment within 5 – 7 business days. Historic homes with suspected asbestos may need an extra day for containment setup planning. Call (361) 326-5060 to check current availability.
Not when done correctly. We use containment barriers, low-suction settings near fragile junctions, and hand-finish in tight attic spaces. Our crews are trained on The Garrison Code: leave the site clean, including any dust that escaped containment.
