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 in South Pasadena, CA
Dryer vent cleaning in South Pasadena runs $149-$289 for a standard single-story home, while whole-system air duct cleaning typically lands between $425 and $780 depending on duct count and accessibility. Homes here present a specific challenge: decades-old retrofit systems threaded through original 1920s and 30s framing, compounded by San Gabriel Valley particulate levels that load ductwork faster than coastal neighborhoods. If you need an exact written price for your home, call (806) 606-6902 and we’ll put it on paper before any work begins.
Why South Pasadena Homes Are Different
South Pasadena’s housing stock skews heavily toward pre-1940 construction: Craftsman bungalows, Spanish Colonial Revival, and Victorian-era homes along streets like Meridian, Diamond, and Chelten Way. These houses were never designed for central HVAC. When systems were added in the 1950s and 60s, contractors ran ductwork through original attic cavities and chases cut into lath-and-plaster walls. That means a technician working in South Pasadena is routinely dealing with 50 to 70-year-old sheet metal, early fiberglass flex that has lost its liner, and cloth-wrapped connections that crumble on contact.
The terrain compounds the problem. South Pasadena sits inland in the San Gabriel Valley, where surrounding hills restrict marine air flow and create stagnant-air episodes that concentrate fine particulates. This part of Los Angeles County regularly records elevated PM2.5 readings. When Santa Ana winds push through the foothills, they carry fine dust and wildfire ash directly into valley homes, accelerating contamination in duct systems that are already compromised by age. Add the city’s dense canopy of mature camphor trees, sycamores, and coast live oaks, and you get exterior return-air intakes collecting decomposed leaf litter at a rate that surprises homeowners who have never looked inside their ductwork.
Our Main South Pasadena Services
Two services account for most of our residential work in South Pasadena: whole-system air duct cleaning and full HVAC cleaning. Both are built around the same reality here, which is that ductwork in this city is older, tighter, and dirtier than what you would find in newer construction.
Air Duct Cleaning in South Pasadena
Air duct cleaning in South Pasadena means working inside tight attic spaces on retrofitted systems that have rarely been accessed since installation. We photograph every duct run before and after, so you see exactly what was inside: decades of dust, construction debris from mid-century retrofits, and organic matter pulled in through exterior intakes shaded by mature trees. Our negative-pressure extraction equipment from Rotobrush and Nikro pulls contaminants out without pushing them into living spaces. For a full breakdown of this service, see Air Duct Cleaning in South Pasadena.
HVAC Cleaning in South Pasadena
HVAC cleaning in South Pasadena goes beyond the ducts to the blower, coils, drain pan, and plenum. Older systems here often have debris caked onto evaporator coils and blower cages, which reduces airflow and forces equipment to work harder. We document component condition with photos before cleaning begins. For details on what this service includes and what it costs, see HVAC Cleaning in South Pasadena.

BeforeAfterDryer Vent Cleaning in South Pasadena
Dryer vent cleaning in South Pasadena costs $149-$289 for most single-story homes, though two-story homes with long vertical vent runs can push toward $349. Pre-war homes here often have dryer vents that exit through original wood siding or through roof caps added decades after construction, and the combination of tight chases, right-angle elbows, and decades of lint accumulation creates a fire risk that most homeowners never see. Our full service is documented on the Dryer Vent Cleaning hub page, but here is what South Pasadena jobs actually involve.
Dryer Vent Inspection
Signs you need it
Clothes take longer than 45 minutes to dry, or the laundry room feels humid while the dryer runs.
What it costs in South Pasadena
An inspection alone runs $49-$99, and the fee is credited toward cleaning if we do the work same-day.
How we do it
We run a camera through the full vent run, photograph every elbow and termination point, and show you the images before recommending any work.
Vent Cleaning
Signs you need it
The outside vent flap barely opens during a cycle, or you can see lint built up around the exterior termination.
What it costs in South Pasadena
Standard vent cleaning runs $149-$289 depending on run length and accessibility, with two-story runs hitting $349 in some cases.
How we do it
We use a rotary brush system with negative-pressure collection at the termination point, then photograph the full run before and after.
Lint Removal
Signs you need it
Lint is visible at the vent opening or you smell a burning odor when the dryer runs on high heat.
What it costs in South Pasadena
Lint removal is included in vent cleaning; as a standalone, it runs $129-$199 for straightforward single-story runs.
How we do it
We extract compacted lint from the full run using professional-grade equipment, then document the cleared path with photos at each elbow.
What Dryer Vent Cleaning Costs in South Pasadena
| Item | Typical range in South Pasadena |
|---|---|
| Dryer vent inspection | $49-$99 (credited toward cleaning) |
| Standard dryer vent cleaning | $149-$289 |
| Two-story or long-run vent cleaning | $289-$349 |
How often should dryer vents be cleaned in South Pasadena?
Every 12 to 18 months for most South Pasadena homes, more often if you have a long vertical run or live under dense tree cover. Call (806) 606-6902 for a written price.
Can you clean a dryer vent that exits through the roof?
Yes. Roof terminations are common on older South Pasadena homes, and we have the equipment to clean them safely. Written pricing is always provided before work starts.
Duct Repair & Sealing in South Pasadena
Duct repair and sealing in South Pasadena addresses a chronic problem in this housing stock: decades-old duct systems with failed connections, degraded mastic, and cloth-wrapped joints that have separated inside original attic cavities. When ducts leak, conditioned air escapes into uninsulated attics, which means your system runs longer to hit the thermostat setting. Our full capabilities are outlined on the Duct Repair & Sealing hub page, but here is what matters in South Pasadena specifically.
Duct Sealing
Signs you need it
Rooms at the end of a duct run are noticeably warmer in summer, or your energy bills climb year over year without a change in usage.
What it costs in South Pasadena
Whole-system duct sealing runs $425-$780 depending on the number of accessible runs and attic configuration.
How we do it
We locate leaks by hand and with a pressure test, seal each joint with mastic or foil tape, and photograph every sealed connection.
Flex Duct Repair
Signs you need it
You see crushed, kinked, or torn sections of insulated flex in the attic, often near framing members where installers pulled runs decades ago.
What it costs in South Pasadena
Replacing damaged flex duct sections runs $325-$575 for typical South Pasadena attic access, depending on how much of the run is compromised.
How we do it
We remove the damaged section, install properly sized and insulated replacement flex, and document the repair with before and after photos.
What Duct Repair & Sealing Costs in South Pasadena
| Item | Typical range in South Pasadena |
|---|---|
| Whole-system duct sealing | $425-$780 |
| Flex duct section replacement | $325-$575 |
| Duct insulation replacement | $300-$500 |
Why do ducts leak so often in South Pasadena homes?
Because most ductwork here was retrofitted into original 1920s and 30s framing, with connections made through tight chases that pulled apart over time. Cloth-wrapped joints degrade. Call (806) 606-6902 for a written inspection price.
Does duct sealing actually lower energy bills?
Yes. Leaky ducts can lose 20 to 30 percent of conditioned air into unconditioned attics. Sealed ducts mean your system cycles less, and our photo record shows every joint we repaired.
Air Quality & Sanitizing in South Pasadena
Air quality and sanitizing work in South Pasadena runs $325-$575 for whole-system sanitizing, with UV light installation carrying additional equipment costs. The combination of stagnant San Gabriel Valley air, Santa Ana dust events, and the city’s dense tree canopy means that even clean ducts can carry biological growth in older homes where attic ventilation was never upgraded. Our full scope of work is documented on the Air Quality & Sanitizing hub page, but here is what South Pasadena homeowners should know.
Mold Treatment
Signs you need it
You or your family experience allergy symptoms indoors that improve away from home, or you see visible growth around registers and inside duct openings.
What it costs in South Pasadena
Mold treatment runs $325-$575 for a typical South Pasadena system, depending on the extent of contamination and how many duct runs are affected.
How we do it
We photograph the affected areas, treat with an EPA-registered antimicrobial, and include a full before and after photo record in your job file.
Odor Removal
Signs you need it
Musty, stale, or smoke odors persist after cleaning surfaces and changing filters, indicating the source is inside the ductwork itself.
What it costs in South Pasadena
Odor removal runs $200-$400, depending on whether it is a targeted treatment or a full-system application.
How we do it
We apply a professional-grade deodorizing treatment to the full duct system using equipment from Abatement Technologies, then verify the result with a return visit if needed.
What Air Quality & Sanitizing Costs in South Pasadena
| Item | Typical range in South Pasadena |
|---|---|
| Whole-system sanitizing | $325-$575 |
| Odor removal treatment | $200-$400 |
| UV light installation | $425-$700 |
Does UV light installation really improve air quality in South Pasadena homes?
UV light systems can reduce microbial growth on coils and inside the plenum when properly sized and installed. We install Aprilaire and Honeywell units and photograph the placement as part of your job record. Call (806) 606-6902 for a written price.
How do I know the sanitizing work was actually done?
Every job includes a documented photo record of the inside of every duct run before and after treatment. You see the same images our technicians see. That is Haven Standard Clause 5: Documented Results.
Brands We Service in South Pasadena
We work on and install equipment from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. Parts for common systems are stocked locally, which keeps turnaround on most South Pasadena jobs to a single visit. See our brands for the full roster of equipment we use and service.
