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.

AfterFast, Reliable Air Duct Cleaning Across East Pasadena
Air duct cleaning in East Pasadena typically runs $350 – $650 for a full residential system and is scheduled within a few business days, with our Los Angeles office coordinating dispatch to your neighborhood. We’re familiar with the raised foundations along Colorado Boulevard, the original 1920s bungalows near the Eaton Wash, and the mid-century ranches tucked between Michillinda Avenue and Rosemead Boulevard. Our crews carry the tools to handle what those older homes throw at us: undersized returns, galvanized ducts wrapped in aging insulation, and the dust that Santa Ana winds push through every attic vent from June through October. If your vents are blowing more than air, call (361) 326-5060. We’ll give you a written price before we touch anything.

Ductwork Cleaning in East Pasadena
Ductwork Cleaning in East Pasadena means dealing with systems that were never designed for modern air conditioning. Most homes here were built between 1920 and 1950 with gravity-furnace ducts sized for heating only, then retrofitted with forced-air AC decades later. The result is undersized returns and leaky collar connections that pull attic dust and crawlspace debris straight into your living space. Our crews use Rotobrush rotary brush systems and Nikro negative-air machines to dislodge and extract what those original ducts have accumulated over 70-plus years.
A typical residential Ductwork Cleaning in East Pasadena runs $350 – $550 for a single-system home, with larger or multi-zone systems reaching $650. Commercial properties start around $800 depending on square footage and access.
Supply Duct Cleaning
Supply ducts push conditioned air into your rooms, but in East Pasadena’s original bungalows they often run through unconditioned attics where summer temperatures exceed 140°F. That heat degrades any remaining duct liner and bakes dust into the metal. We clean supply lines with rotary brushes that follow the duct contour, then verify airflow at each register.
Return Duct Cleaning
Return ducts are the intake side, and in East Pasadena they’re frequently the weak link. Original returns were sized for gravity furnaces, not modern blowers, so they’re too narrow and run too slowly. That low velocity lets dust settle and mold take hold in winter-damp crawlspaces. We clean returns with negative-air extraction to prevent cross-contamination during the job.
Air Duct Inspection in East Pasadena
Air Duct Inspection in East Pasadena should happen before any cleaning work is quoted, because what we find in these older homes changes the scope and the price. Our video inspection sends a lighted camera through your ductwork to document cracks at collar joints, standing water in low spots, and the condition of any insulation wrapping. In East Pasadena specifically, we’re also looking for original 1940s – 50s round galvanized ducts wrapped in failing asbestos-containing insulation. That’s a local code and safety quirk that changes how the job must be handled compared to newer neighboring cities, and we won’t start work until we know what we’re dealing with.
An Air Duct Inspection in East Pasadena costs $150 – $250, which is credited toward your cleaning if you proceed. We recommend an inspection if you’ve never had your ducts cleaned, if you recently purchased an older home, or if you’re noticing uneven temperatures between rooms.
Video Documentation
Our inspections include before-and-after video of your own ducts, not stock footage. You see what we see: the dust buildup at the elbows, the gaps where mastic has cracked away, the debris that shouldn’t be there. That footage becomes part of your written record and supports your warranty claim if needed.
System Mapping
Many East Pasadena homes have had HVAC retrofits that left ductwork undocumented. We trace your system, label each run, and note where original ducts were extended or modified. That map helps us clean completely and helps you plan future maintenance or Duct Sealing in East Pasadena.
Trusted Brands We Service in East Pasadena
Our equipment roster includes Rotobrush rotary brush systems and Nikro negative-air machines for the cleaning work itself, plus filtration products from Honeywell, Aprilaire, and Guardsman for homeowners who want to upgrade after we clear the ducts. We also carry Abatement Technologies HEPA filtration for jobs where asbestos-containing insulation is present. For East Pasadena customers, that means we don’t special-order parts or make you wait. If your 1950s system needs a compatible register boot or a modern collar adapter to seal properly after cleaning, we stock what fits the local housing stock. Our Los Angeles office keeps inventory matched to the retrofits we see most often in older Pasadena-area homes.
Common Air Duct Cleaning Problems We See in East Pasadena Homes
- Asbestos-wrapped galvanized ducts in pre-1960 bungalows. The original 1940s – 50s round ducts in neighborhoods near Colorado Boulevard and Michillinda Avenue often carry aging insulation that contains asbestos. Disturbing it without proper containment violates local codes and creates a health hazard. We identify this during inspection and follow abatement protocols if needed.
- Undersized returns choking modern AC systems. Homes built for gravity furnaces have return ducts too narrow for today’s higher blower speeds. That restriction creates negative pressure that pulls dust through every leak. Cleaning helps, but we also flag where Duct Sealing in East Pasadena would solve the root problem.
- Santa Ana dust loading in attic ductwork. The hot, dry winds that sweep through from September to November push fine dust through attic vents and soffits. In East Pasadena’s unconditioned attics, that dust settles on duct exteriors and infiltrates through gaps at joints. We find it packed around the boots and elbows during every summer-season cleaning.
- Winter moisture and mold in crawlspace ducts. Rainy season dampness collects in under-floor crawlspaces, especially in raised-foundation homes near the Eaton Wash. Ducts sitting in that humidity grow surface mold that spores into the system when the blower starts. Our negative-air method extracts visible growth and we document where replacement is the safer option.
