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 $420-$780 for a full single-family home, depending on the number of duct runs, system accessibility, and whether the return side needs heavy debris removal. Most jobs take four to seven hours and include a camera inspection before work starts, a documented photo record of every run when we leave, and a written price agreed to before a single panel comes off.
We work throughout South Pasadena regularly, from the tree-lined streets off Fair Oaks Avenue up to Monterey Hills. Crews are dispatched locally, not from across the county, which means less scheduling friction and crews who already know what a 1920s Craftsman attic looks like. If you want a written price and a straight answer, call (806) 606-6902.
Why CleanRun Air Duct Cleaning Is South Pasadena’s Preferred Air Duct Cleaning Company
The homes we clean here were mostly built before 1940. That changes the work. We’re not walking into a 2005 tract house with accessible attic trusses and modern flex duct. We’re going into tight attic cavities threaded through original timber framing, pulling original sheet metal from the 1960s, and working around lath-and-plaster walls that do not forgive clumsy access cuts. South Pasadena homeowners tell us consistently that another company quoted low, showed up with a shop vac, and left without a single photo of what they actually did. We hear that because we get called after those jobs to fix them.
Every South Pasadena job ends with a documented photo record. You see the inside of the return duct before we start, and you see that same duct when we finish. Not a stock photo. Your ducts, your address, your job. That’s Haven Standard Clause 1 in practice: a written price before work begins, and haven Standard Clause 3: a verified crew, background-checked and uniformed, who arrive with a name, not a truck number. Led by Tomas Reyes, CleanRun has held this standard since our first job in 2013. We don’t ask you to trust a brand. We hand you the evidence.
South Pasadena is a small city with an old housing stock, and word travels here. We’ve cleaned ducts in homes off Mission Street, up near the Arroyo Seco, and through the apartment courtyards along Huntington Drive. Homeowners here compare notes. What gets us the call is the same thing that gets us the referral: written pricing, a real camera inspection, and a job record that proves the work happened.
Our Air Duct Cleaning Services in South Pasadena
Residential Duct Cleaning
Most of what we do in South Pasadena is residential cleaning for pre-war homes with retrofitted central HVAC. These systems were not part of the original house. They were added decades later, often through attics never meant for maintenance access. We clean supply and return ductwork under negative pressure with HEPA-filtered collection, and we photograph every run before and after.
A typical three-bedroom Craftsman in South Pasadena has 10 to 14 duct runs. The return side, usually one or two large runs pulling from a central hallway or wall vent, often carries more debris than the supply side. We address both, and we always check the return intake opening before we assume the job is straightforward. Roof overhangs and mature tree canopies mean exterior return grilles can be half-blocked with leaf litter before we ever touch indoor ductwork.
Commercial Duct Cleaning
South Pasadena’s commercial buildings are mostly small-storefront and low-rise professional offices, many in structures that predate central air. Duct systems in these spaces are often shallow, boxed-in, and serviced irregularly. We clean restaurant kitchen exhaust ducts, office HVAC runs, and return plenums in retail storefronts along Mission Street and Fair Oaks Avenue.
For property managers and building owners, we coordinate around tenant hours and provide the same documented photo record we give to residential customers. Written price first, no exceptions. If a commercial tenant has been complaining about dust or stale air, a camera inspection usually shows why within the first 20 minutes.
Supply Duct Cleaning
Supply ducts push conditioned air into your rooms. In South Pasadena’s retrofitted systems, those runs are often original 1950s or 1960s sheet metal, or early fiberglass flex pulled through wall chases that were never designed for replacement. Supply runs accumulate what the filters miss: fine dust, skin cells, pet dander, and in homes near the San Gabriel foothills, a surprising amount of wildfire ash.
We clean supply runs from the register boots back to the plenum, using professional-grade negative-pressure extraction with equipment from Rotobrush and Nikro. We do not perform a “blow-and-go” air-wash. The equipment pulls contaminants out through a sealed collection system, not into your living room.
Return Duct Cleaning
In South Pasadena homes, return duct cleaning is typically where the real filth lives. The return side draws air from inside the house back to the blower. In older homes, that air passes through floor or wall cavities that have been accumulating dust for six decades. We regularly find 2 to 4 inches of compacted debris in the first elbow of a return run.
Return duct cleaning in South Pasadena also means checking the actual intake opening, not just the ductwork behind it. Shaded homes get leaf litter, sycamore seed balls, and sometimes rodent nesting material in the return boot. We remove it mechanically, clean the exposed run, and photograph the result. A clean return side means the blower isn’t starving for air and the system isn’t redistributing attic dust into your bedrooms.

BeforeAfterTrusted Brands We Service in South Pasadena
We clean and service duct systems connected to equipment from Honeywell and Aprilaire, among others. Many South Pasadena homes still run older thermostats and air-quality accessories from these brands, and we’re familiar with how their filtration and control systems integrate with retrofitted ductwork. If you have an Aprilaire media cabinet or a Honeywell whole-house filter installed, we include those housings in our inspection scope at no extra charge. We also use Abatement Technologies HEPA-filtered negative air machines during source removal, which matters if you have pets, allergy concerns, or a home that’s been through even a small renovation.
Common Air Duct Cleaning Problems We See in South Pasadena Homes
- Leaf-packed return intakes. South Pasadena’s camphor trees and sycamores drop fine organic debris that pulls straight into exterior return grilles. Homes with gable vents or low wall intakes near rooflines see the worst of it. That debris breaks down inside the duct, feeds biological growth, and restricts airflow.
- Cloth-wrapped connections from the 1960s. Original sheet metal runs often have canvas or cloth connectors at the plenum and register boots. After 50 to 70 years in a hot attic, that fabric frays. We find attic insulation and dust being pulled straight into the air handler through degraded connections.
- Undersized retrofitted runs. A 1920s bungalow was never designed for central air. Duct runs squeezed into original framing are frequently undersized for modern blower CFM. That means higher static pressure, more dust impaction on duct walls, and more frequent contamination than a properly designed modern system.
- Shared dryer vent stacks in apartments. South Pasadena has a stock of 1950s and 60s courtyard apartments with shared vent risers. One unit’s dryer pushes lint into the stack, and gravity deposits it back down into the lower unit’s lateral. We clean shared stacks when building managers coordinate access, and we document the blockage before it becomes a fire hazard.
Pricing for Air Duct Cleaning in South Pasadena, CA
Let’s get specific, because that’s the whole point. A full air duct cleaning for a typical South Pasadena single-family home runs $420 to $780. Smaller bungalows with six to eight runs often land between $380 and $520. Larger two-story homes or houses with long return runs from multiple floors can reach $850 to $1,100. Condos and apartments in South Pasadena usually run $280 to $450 per unit, depending on run count and access.
What moves the price: the number of supply and return registers, whether the attic is accessible without boarding or crawlspace tricks, how much debris is actually packed in the return side (we see more in older shaded homes), and whether there’s a second system or a separate garage-apartment run. You get the written price before work starts. Not an estimate range by phone. A written scope and number. Bring a competitor’s written quote and we’ll put our number next to it as a free second opinion. That’s the CleanRun standard, and it’s been that way since 2013.

FAQs - Air Duct Cleaning in South Pasadena
South Pasadena’s Craftsman-era homes need return duct cleaning more because the return side runs through original wall cavities and attic spaces that have been collecting dust, insulation fibers, and pulverized leaf debris for six or more decades. Supply runs see filtered air. Return runs see unfiltered household air. In a 1930s house with a 1960s retrofit, the return plenum is often the single dirtiest segment of the entire system. That’s why our camera inspection always starts there. If you suspect your return side has never been opened, call (806) 606-6902 and we’ll give you a written clean-and-inspect price before any work starts.
We work through original access hatches, closet scuttles, and in some cases the exterior gable vent, using compact negative-pressure machines and sectional vacuum hose rather than bulky single-piece equipment. South Pasadena’s narrow driveways and tight street parking are a real consideration, so we stage equipment in a short wheelbase van and carry tools to the attic instead of trying to park a trailer in front of a 1922 bungalow. The work doesn’t get sloppier because the access is harder. It just requires a crew that actually knows how to work in 90-degree attic cavities with minimal demolition.
Yes. South Pasadena sits inland in the San Gabriel Valley, and surrounding terrain limits marine air penetration, which means stagnant air episodes concentrate particulates. The area regularly posts some of the higher PM2.5 readings in Los Angeles County, and seasonal Santa Ana winds drive fine dust and wildfire ash from the San Gabriel foothills straight into valley homes. We recommend every three to five years for most South Pasadena homes, but houses within a block or two of the foothills with constant ash settlement, or homes with mature tree canopies directly overhanging exterior intakes, often need it every two to three years.
The signs are usually visible and predictable. Dust re-accumulates on register grilles within days of cleaning them. The system runs louder than it should because return restrictions are starving the blower. You smell a musty or vaguely sweet odor when the fan kicks on, especially after the system has been off. And a camera inspection reveals heavy dust and debris in the first elbow of a return run, because no one before us ever opened it. If you’re seeing any of these, call (806) 606-6902. We’ll provide a written diagnosis and the exact price to correct it, before any work starts.
We coordinate directly with the property manager or owner to schedule access to the vertical stack and the individual lateral runs during a single service window. Our techs clean the stack from the roof vent, then clean each unit’s lateral back to the stack connection. Units not involved in the cleaning window are left untouched. Every segment gets photographed before and after, and the building owner receives a complete photo record for their maintenance file. This process usually takes one to two hours for a four-to-six unit South Pasadena courtyard apartment, and the written price is set before any access work begins.
