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 $350-$650 for a full residential system and $500-$1,200 for commercial setups, with most jobs scheduled within a few days of your call. We’re Morton’s Air Duct Cleaning, and we’ve been serving families in this corner of the San Gabriel Valley since 2005. Our crews know the difference between a 1920s Craftsman on Bank Street and a mid-century ranch off Fair Oaks, because those houses don’t have the same ducts, and they sure don’t have the same problems.
Dispatch and scheduling are coordinated from our Los Angeles office, but our technicians live and work throughout the San Gabriel Valley. That means when you call (323) 918-4345, you’re talking to someone who understands why the Santa Ana winds hit your intake vents harder here than in coastal neighborhoods, and why the January 2025 Eaton Fire left ash in places standard cleaning equipment can’t reach. We bring shoe covers, drop cloths, and a written price before we touch anything. No surprises on the invoice. No mess left behind.
Why Morton’s Air Duct Cleaning Is South Pasadena’s Preferred Air Duct Cleaning Company
South Pasadena families call us back because we treat their homes the way we’d want our own treated. Our Air Duct Cleaning team has built a reputation on the older blocks near Garfield Park and the historic districts along El Centro Street, where homeowners are protective of original woodwork and tired of crews who track in dust or try to upsell once they’re inside.
Every technician is background-checked, arrives in uniform, and works to the Cedarwell C.A.R.E. values. That means shoe covers and drop cloths from the moment we walk in, quieter tools during nap hours, and pet-safe product choices where available. We provide a written price before any work starts, every single time, backed by our 365-Day Done Right Promise. If something isn’t right, we make it right. Full stop.
A live person answers our phones 24 hours a day. Not a voicemail tree. Not a chatbot. A real human who can schedule your free estimate, answer questions about your specific system, and note that you’ve got a toddler down the hall or a senior dog who startles easily. And every completed job includes a photo of the clean-up before our crew leaves, so you have visual proof your home was left better than we found it.
Air Duct Cleaning Services in South Pasadena
Air Duct Cleaning Services in South Pasadena address a specific challenge: most homes here were built before forced-air HVAC existed, meaning duct systems were retrofitted through attics and wall cavities never engineered for them. Our process starts with a video inspection using a borescope camera, so we see what we’re dealing with before we quote a price. We then use Rotobrush agitation tools and Nikro HEPA-negative-air equipment to dislodge and capture debris, not just move it around. A typical residential cleaning in South Pasadena runs $350-$650 depending on system size and accessibility, with whole-system cleans at the higher end when we’re dealing with multiple attic access points or deteriorated liner sections.
Residential Duct Cleaning
Homes near Mission Street and the historic Arroyo Seco neighborhoods often have supply ducts routed through original redwood-framed attics with tight turns that trap debris. We camera-inspect first, then select agitation tools matched to your duct material, flexible liner, or fiberboard. Our crews protect floors with drop cloths, work around your schedule, and leave a photo of the clean space behind.
Commercial Duct Cleaning
Small offices and retail spaces along Fair Oaks Avenue and Huntington Drive need scheduled cleanings that don’t disrupt business hours. We work early mornings or weekends, provide the same written upfront pricing, and document the work with before-and-after photos for your maintenance records.

HVAC Duct Cleaning in South Pasadena
HVAC Duct Cleaning in South Pasadena requires understanding how this city’s unique conditions stress forced-air systems. Sitting at the western mouth of the San Gabriel Valley, South Pasadena catches Santa Ana wind events that funnel fine desert dust directly into exterior intakes. Add proximity to the San Gabriel Mountain foothills and the South Coast Air Basin’s consistently poor PM2.5 rankings, and your ducts load with particulate faster than coastal communities experience. A typical HVAC duct cleaning here runs $400-$750 for residential systems, with costs climbing when we encounter the original 1960s flex connections common in pre-1940 retrofits.
Full System Cleaning
We clean supply ducts, return ducts, trunk lines, and the air handler cabinet as one integrated system. Partial cleanings miss the debris that migrates between components. In South Pasadena’s irregular retrofit ductwork, this matters more than in new construction with straight runs.
Video Inspection
Our borescope cameras navigate the tight offsets and bends of your attic ducts, showing you exactly what we’ve found before we quote. After the Eaton Fire, this step proved critical. Homeowners who’d had “clean” ducts two years prior watched footage of packed gray ash that standard methods had completely missed.
Trusted Brands We Service in South Pasadena
We clean and maintain systems using professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, not rental-shop gear that loses suction halfway through a job. For filtration upgrades and component replacements, we work with Aprilaire and Guardsman products matched to your system’s specifications. Because we’re part of the Cedarwell family with coordinated dispatch from Los Angeles, we can source parts quickly for South Pasadena customers without the delays that strand you waiting on a specialty order. Our technicians train on each manufacturer’s equipment, so the tools that touch your ducts are the ones designed for the work, not adapted from some other trade.
Common Air Duct Cleaning Problems We See in South Pasadena Homes
- Fire particulate packed into 1960s flex connections. After the Eaton Fire, our crews found original retrofit flex in Craftsman attics loaded with fine gray ash that standard brush-and-vacuum passes couldn’t dislodge. Without HEPA-negative-air equipment, that ash redistributes through your home every time the blower cycles.
- Liner deterioration in irregular attic runs. Pre-1940 homes retrofitted with forced air often have ductwork routed through spaces never meant to carry it. Aging flex liner and fiberboard sections tear under aggressive agitation if a tech doesn’t camera-inspect first and match tools to the material.
- PM2.5 loading from South Coast Air Basin conditions. South Pasadena’s daily outdoor air quality loads ducts faster than coastal cities. Homeowners who moved from Long Beach or Santa Monica often assume the same 3-5 year cleaning interval applies. It doesn’t.
- Blocked returns in tight wall cavities. Retrofit return ducts squeezed between studs in historic homes collect debris at elbows and transitions that modern ductwork simply doesn’t have. We locate these restrictions with camera inspection before cleaning, not after we’ve already quoted.

FAQs About Air Duct Cleaning in South Pasadena
Pre-1940 South Pasadena homes with retrofit ductwork need cleaning every 2-3 years, not the 3-5 year interval that works for newer construction. The irregular runs, tighter bends, and original liner deterioration in these Craftsman and Spanish Colonial systems trap debris that straight modern ductwork sheds. Temple City’s post-war ranch homes with original designed ductwork can often go longer between services. Call (323) 918-4345 to schedule an inspection and we’ll tell you where your specific system falls.
Standard brush-and-vacuum cleaning doesn’t capture fine wildfire ash packed into original 1960s flex connections and tight attic offsets. That particulate is smaller and more adhesive than household dust. Without HEPA-negative-air equipment and agitation tools matched to deteriorated liner material, the ash stays put until the blower redistributes it. We saw this repeatedly on Craftsman blocks near Garfield Park. Call (323) 918-4345 if you’re seeing gray film on your registers.
Historic preservation ordinances protect exterior character and original interior features, not mechanical systems, so duct cleaning itself isn’t restricted. Where we adapt our approach is in access and protection. We use smaller inspection cameras and flexible tools that navigate tight retrofit cavities without cutting new openings in original plaster or woodwork. Drop cloths and shoe covers are non-negotiable on every visit, but in historic homes we’re especially careful with ladder placement and attic access paths.
We start with video inspection to locate ash accumulation and liner deterioration. Then we establish negative pressure with HEPA filtration using Abatement Technologies equipment, agitate debris loose with Rotobrush tools sized to your duct material, and capture it before it enters your living space. For post-Eaton Fire jobs, we’ve also sealed deteriorated liner sections and rebalanced air handlers after the deep clean. The process takes longer than a standard cleaning, but it’s the only way to actually remove wildfire particulate rather than redistribute it.
We generally recommend MERV 11-13 filters for South Pasadena’s particulate loading, but check your system’s specs first. Older air handlers in retrofit setups may struggle with the airflow resistance of MERV 13+. Higher isn’t always better if it strains the blower or causes freeze-ups. During your cleaning, we’ll inspect the handler capacity and recommend a filter grade that captures PM2.5 without overworking equipment already stressed by irregular duct runs. Call (323) 918-4345 and we’ll assess your specific system.
