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 – $850 for a full residential system, with most jobs scheduled within a few days and completed in four to six hours. We’re familiar with the specific challenges of South Pasadena’s historic housing stock, from the Craftsman bungalows near Mission Street to the Spanish Colonial Revival homes tucked behind Diamond Avenue.
Our crews serve South Pasadena from our Los Angeles scheduling office, carrying the tools and training to handle what these older homes throw at us: unlined galvanized ductwork from the 1920s, asbestos-wrapped pipes requiring abatement certification, and retrofit systems crammed into attics never built for modern HVAC. When you call (361) 326-5060, a live person answers, day or night. We’ll give you a written price before any work starts, and every job carries our 365-Day Done Right Promise.
Why Hollis Air Duct Cleaning Is South Pasadena’s Preferred Air Duct Cleaning Company
We’ve been part of the Garrison Partners family since 2004, and our reputation in South Pasadena is built on showing up when we said we would, pricing in writing, and leaving the site clean. South Pasadena homeowners aren’t looking for the cheapest coupon in the mail; they’re looking for a crew that won’t damage original plaster walls or ignore asbestos hazards in a 1920s attic.
Our technicians are background-checked, uniformed, and trained to The Garrison Standard: arrive inside the quoted window, explain what we’re finding in plain terms, photograph the before and after so you see what came out of your ducts. If the work fails within a year, we come back and make it right at no charge, including a free second visit. That’s not a slogan; it’s written on every job sheet.
Dispatch and scheduling for South Pasadena are coordinated from our Los Angeles office, but the crews working your home know the local terrain: the mature camphor and oak canopies that dump debris into rooftop intakes, the historic preservation overlay that affects how we seal access panels, the pre-1978 lead-safe requirements that govern how we cut into painted ductwork.
Vent Cleaning in South Pasadena
Vent Cleaning in South Pasadena means more than vacuuming the grates you can see from the hallway. In these 1900 – 1930 homes, the supply and return vents often connect to original galvanized duct runs that have never been properly accessed, with decades of dust, pollen, and camphor debris packed into elbows and transitions that a surface cleaning won’t touch.
A typical residential vent cleaning in South Pasadena runs $150 – $350 per system when done as part of a full duct cleaning, or $200 – $450 as a standalone service for a limited vent count. The price is written down before we start, and it doesn’t move at the door.
What We Find Behind the Grate
Most South Pasadena homeowners are surprised by how much debris accumulates in the first few feet behind their vent covers. In homes near the foothills, we regularly pull out fine dust from dry summer air mixed with organic matter from those mature street trees. The rotary brush system from Rotobrush agitates this buildup while our Nikro negative-air machine maintains suction, so nothing escapes into your living space during the cleaning.
When Vent Cleaning Becomes Duct Repair
Sometimes the vent itself is fine, but the duct behind it is crushed, disconnected, or leaking at the joint. We flag this during our video inspection and show you the footage before quoting any repair. No surprise additions to the invoice once we’re inside your home.
Air Duct Repair in South Pasadena
Air Duct Repair in South Pasadena is often the real work hidden inside a “cleaning” call. The 1920s gravity furnaces and early forced-air retrofits in this city’s historic homes weren’t built with maintenance access in mind, so we regularly find crushed supply lines, disconnected returns, and galvanized seams that have rusted through after a century of temperature swings.
Typical duct repair in South Pasadena ranges from $250 – $600 for sealing and patching accessible runs, to $800 – $1,800 for replacing crushed or asbestos-wrapped sections with new lined ductwork. Every repair gets a written price before we cut or seal anything.
Sealing What the Decades Broke
Mastic sealing and mechanical fastening are usually what these old systems actually need. We apply duct sealing mastic to every joint and seam we expose, then pressure-test the repair to confirm airflow is restored to the rooms that were starving. In a 1920s Craftsman near Meridian Avenue last month, this simple sealing work dropped the homeowner’s utility bill by 18% because conditioned air finally reached the back bedrooms instead of leaking into the attic.
Historic-Compatible Access and Repair
When we must cut new access panels into original ductwork, we follow lead-safe practices required for pre-1978 homes and reseal openings to match the historic aesthetic of your property. In preservation-overlay districts, this attention to detail matters. We don’t slap on modern snap-in panels that clash with century-old plaster and woodwork.
Trusted Brands We Service in South Pasadena
Our equipment roster includes Rotobrush rotary brush systems for agitation cleaning, Nikro negative-air machines for source removal under controlled suction, and filtration products from Aprilaire, Abatement Technologies, and Guardsman. We stock common parts and fittings for South Pasadena’s mix of vintage and modern HVAC systems, which means faster turnaround when your repair needs something specific. If your home has an Aprilaire media air cleaner or a Guardsman UV filtration add-on, our technicians know how to remove, service, and reinstall these units without disrupting their calibration. The tools we bring are the same ones commercial crews use on larger buildings, sized down for residential precision.
Common Air Duct Cleaning Problems We See in South Pasadena Homes
- Asbestos-wrapped ductwork from the 1920s. We regularly find original runs wrapped in vintage asbestos insulation, which triggers abatement-certification requirements before any cleaning begins. This turns a routine job into a specialized historic-preservation project that simply doesn’t arise in newer neighboring cities.
- Missing access panels in retrofit systems. Many South Pasadena homes had central air added decades after construction, with ducts squeezed into low-clearance attics and crawlspaces that lack proper access points. Without cutting and resealing new openings, technicians simply cannot reach the far reaches of supply and return lines.
- Crushed or disconnected supply runs. The retrofit work in these older homes often used thin, unlined galvanized duct that collapses under foot traffic in attics or separates at poorly supported joints. We find this most often in the long runs to back bedrooms, where airflow has been weak for years.
- Lead-safe practice requirements on pre-1978 homes. Local code requires contractors to follow strict lead-safe practices when disturbing painted surfaces. Cutting into original ductwork without containment and cleanup protocols violates this standard and can contaminate your living space.
Pricing for Air Duct Cleaning in South Pasadena, CA
A typical full residential air duct cleaning in South Pasadena runs $350 – $850, depending on system size, accessibility, and what we find once we’re inside. Commercial systems in local small businesses start around $600 and scale with square footage and vent count. Dryer vent cleaning, which we often pair with duct work in South Pasadena’s older homes, adds $120 – $250.
What moves the price: homes with original unlined galvanized ductwork requiring careful handling; asbestos-wrapped pipes needing abatement certification; crushed or disconnected runs requiring repair before cleaning is effective; and systems in low-clearance attics where cutting new access panels adds labor.

FAQs About Air Duct Cleaning in South Pasadena
A full residential air duct cleaning in South Pasadena typically costs $350 – $850, with most homeowners landing in the $450 – $650 range for a standard single-system home. Commercial jobs and historic homes with asbestos or complex access issues run higher. Call (361) 326-5060 for a free written estimate on your specific system.
The low teaser prices you see in mailers usually quote a per-vent rate that excludes the main trunk lines, the return plenum, and the actual source-removal equipment. By the time the technician is inside your South Pasadena home, the invoice has tripled. We price the whole system, write it down before we start, and don’t move it at the door.
We photograph the inside of your ducts before and after, and we show you the footage. In South Pasadena’s older homes with limited access, we also use our video inspection camera to document that the far reaches of your supply and return lines were reached, not just the easy spots near the vents.
For most South Pasadena homes, every three to five years is sufficient, though homes with original unlined ductwork, heavy tree debris from those mature camphor and oak canopies, or residents with allergies may benefit from more frequent service. After any major renovation or asbestos abatement work, we recommend an immediate inspection.
South Pasadena’s Mediterranean climate pulls fine dust from the dry, hot air and nearby foothills into your HVAC system all summer long, while winter rains raise indoor humidity that can promote mildew in poorly sealed ducts. Cleaning removes the accumulated debris, but sealing the system against these seasonal cycles is what keeps it from building back up. Our 365-Day Done Right Promise covers both the cleaning and any sealing work we perform, so if airflow drops or odors return within a year, we come back at no charge.
