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 South Pasadena
Air duct cleaning in South Pasadena typically runs $450 to $950 for a full residential system, and most homes here take us four to six hours because the ductwork itself is usually older, tighter, and more compromised than what you’d find in a newer build. If you live in one of the Craftsman bungalows or Spanish Colonials near Marengo Avenue or the Mission Street corridor, there’s a good chance your ducts were never designed for the home at all. They were retrofit in decades ago, and they’ve been collecting dust, rodent debris, and wildfire ash since. Call (980) 447-2498 and we’ll give you a written price before any work begins.
Linden Air Duct Cleaning works throughout South Pasadena, and our crews know exactly what these older systems look like when we open them up. That matters. A technician who only knows new-construction ductwork will misread what they’re seeing in a pre-war attic. We don’t.
Why Linden Air Duct Cleaning Is South Pasadena’s Preferred Air Duct Cleaning Company
South Pasadena homeowners call us because we tell them who is coming to their door before the van arrives. Every technician is background-checked and identity-verified under the Threshold Standard. You get the tech’s name and photo sent to you ahead of the visit, and they show a photo ID badge at the door. That protocol has been in place since 2004, and it is not a promotional offer. It is how we work.
We also put the price in writing before any tools come off the truck. One flat price per system, agreed before work starts. If a repair is part of the job, that repair carries a written guarantee and a free second visit if it does not hold. Every job, every time. Our Air Duct Cleaning crews run Rotobrush and Nikro negative-pressure equipment with HEPA filtration, which is the only way to do source removal properly in homes built between 1905 and 1940.
Local knowledge counts here. South Pasadena’s housing stock is older than most of the San Gabriel Valley, and the duct systems were retrofitted by hand, often badly. We know what to look for in those attics because we see the same failure patterns week after week. That is why homeowners in South Pasadena keep our number. Call (980) 447-2498 and speak to a live person, any hour.
Air Duct Cleaning Services in South Pasadena
Air Duct Cleaning Services in South Pasadena start with a camera inspection of the full run, because you cannot clean what you cannot see. In most of these homes, the ductwork sits in an unconditioned attic where flex has sagged, disconnected, or been chewed through by roof rats. We inspect first, quote a written price, then do source removal under negative pressure with HEPA filtration before any agitation tools go in.
Residential and Full System Cleaning
A full residential clean in South Pasadena covers supply ducts, return ducts, the air handler, and the plenum. On older retrofit systems, we typically find disconnected joints at the trunk that are pulling attic air straight into the living space. Sealing those joints is part of the job when we find them, and it is often the single biggest improvement in airflow.
Video Inspection and Supply and Return Runs
We run video inspection the full length of supply and return runs before and after cleaning. That gives you photographic proof of what was removed and what was sealed. If a run is collapsed or shredded by rodent activity, you’ll see it on camera, and we’ll show you before-and-after footage of your own system, not a stock photo.

HVAC Duct Cleaning in South Pasadena
HVAC Duct Cleaning in South Pasadena means cleaning the entire forced-air pathway, not just the visible registers. In these pre-war homes, the HVAC system was added decades after the house was built, and the retrofit flex duct was rarely installed with proper chases or support. Dust settles in low spots, rats nest in the gap-prone eaves, and Santa Ana winds push desert dust and mountain wildfire smoke straight through the Arroyo Seco gap into your attic.
Return and Supply Duct Cleaning With Sealing
Most homes in South Pasadena have return runs pulling from a central hallway and supply runs pushed through tight attic paths. When those runs are disconnected at joints, cleaning alone will not fix the airflow problem. We clean the full run and seal any disconnections we find. On a 1912 Craftsman off Marengo Avenue, our tech pulled the return access panel and found original 1970s flex still stapled to century-old redwood rafters, the inner liner shredded by roof rats and collapsed into the run. We cut out and replaced the compromised sections, sealed the disconnected joints at the air handler and trunk, and did source removal under negative pressure with HEPA filtration. The system went from barely moving air at the far registers to balanced supply and return across all rooms.
Air Handler and Plenum Cleaning
The air handler and plenum are where the system’s air actually passes through the blower and into the ductwork. On older South Pasadena systems, these components are often original or decades old, and they collect a fine layer of dust and debris that recirculates through the house. We clean them as part of every full-system job. If the plenum wrap contains asbestos-containing material, we stop and recommend a pre-disturbance inspection before any cleaning proceeds.
Trusted Brands We Service in South Pasadena
We clean and repair ductwork across all major brands and configurations, but the gear we run matters just as much as the systems we service. Our crews use Rotobrush and Nikro negative-pressure extraction equipment, and we work with air-quality products from Aprilaire and Abatement Technologies when filtration or purification is part of the job. That professional-grade equipment is what lets us do true source removal in tight South Pasadena attics where lesser machines simply cannot reach. Call (980) 447-2498 and we’ll walk you through what we use on a home like yours.
Common Air Duct Cleaning Problems We See in South Pasadena Homes
- Disconnected retrofit flex in tight attics. Pre-1940 Craftsman and Period Revival homes in South Pasadena rarely have proper duct chases. The retrofit flex sagged and pulled apart at joints decades ago, so air bypasses the run and pulls attic dust into living space.
- Roof rat damage to inner duct liners. The gap-prone wood-frame construction common in these homes lets roof rats into attics regularly. They chew through flex duct and shred the inner lining, and the contamination reoccurs unless entry points are sealed alongside the clean.
- Asbestos-era plenum and wrap materials. Original plenums and duct wrap from the 1905 – 1940 era sometimes contain asbestos-containing materials. Disturbing them without a pre-cleaning inspection risks a much bigger problem than dirty ducts.
- Wildfire ash and Santa Ana-driven particulates. South Pasadena sits at the foot of the San Gabriel Mountains, and Santa Ana winds funnel desert dust and Angeles National Forest wildfire ash directly through the Arroyo Seco corridor. That fine particulate settles into leaky, aging duct systems at a higher rate than most of coastal LA.
Pricing for Air Duct Cleaning in South Pasadena, FL
A typical single-system residential air duct cleaning in South Pasadena runs $450 to $950, depending on the number of supply and return runs, the condition of the ductwork, and whether sealing or section replacement is required. Larger homes with multiple systems or extensive rodent damage can run higher, and we will show you exactly why before you approve anything. What we will not do is quote a low teaser price and then inflate it once the van is parked in your driveway.

FAQs About Air Duct Cleaning in South Pasadena
Because the ductwork in a 1920s bungalow was not part of the original home. It was retrofitted decades later, usually as flex duct run through an unconditioned attic with no designed chases. Over time that flex sags, disconnects at joints, and pulls attic air straight into your living space. Cleaning removes the debris, but sealing is what actually stops the contamination from coming back. We quote both parts of the job separately so you know exactly what each costs. Call (980) 447-2498 and we’ll explain what your specific system needs.
In most Craftsman-era homes along Marengo Avenue and the Mission Street corridor, we find original 1960s to 1980s flex duct still stapled to redwood rafters. The inner liners are often collapsed or shredded by roof rats, and joints are disconnected at the air handler and trunk. We run camera inspection the full length so you can see it yourself before we quote any work.
Yes, in some of these 1905 – 1940 homes the original plenums and duct wrap contain asbestos-containing materials. We do not disturb those materials without a pre-cleaning inspection. If we see anything that looks suspect on camera, we stop and recommend a licensed asbestos inspection before proceeding. That protects you and our crew, and it is the right way to handle a historic home.
South Pasadena sits directly in the path of Santa Ana winds that carry desert dust and San Gabriel Mountain wildfire smoke through the Arroyo Seco gap. Fine particulates deposit into leaky, aging duct systems here at a rate higher than most of coastal LA. Pair that with seasonal dry conditions that desiccate old flex interior linings, and you get faster debris accumulation and more brittle ductwork than a coastal home would see.
Yes. Every full-system cleaning we perform in South Pasadena follows NADCA standards and uses negative-pressure extraction with HEPA filtration. That means the system stays under negative pressure while agitation tools work inside, so debris is pulled into the filtration unit rather than blown into your living space. That is the only method we use, and we will verify it in writing before the job starts. Call (980) 447-2498 for a free estimate.
