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.

Homes here aren’t like inland South Bay properties. The landslide complex running from Portuguese Bend through Abalone Cove means ground creep racks and twists ductwork in ways that simply don’t happen in Torrance or Carson. We’ve found flex runs pinched flat at foundation shifts and metal trunks pulled open at seams. That’s why our Rancho Palos Verdes work always includes leak detection alongside source removal, not just vacuuming dust. We know the 1950s – 1970s ranch and split-level stock, the long hillside runs, and the marine-layer moisture that keeps duct interiors damp enough for mold growth. Roy Castellanos and our team have built our reputation on showing up, pricing in writing, and standing behind the work for a full year.
Why Hollis Air Duct Cleaning Is Rancho Palos Verdes’s Preferred Air Duct Cleaning Company
We’ve been in business since 2004 as part of the Garrison Partners family, and our Rancho Palos Verdes customers come back because we operate on The Garrison Standard: arrive inside the window, price in writing, complete the job by the book, and leave the site clean. No estimates that balloon once the technician is inside. No voicemail loops when you call. Phones are answered by a live person 24 hours a day, 7 days a week.
Our technicians are background-checked and uniformed. You know who’s walking into your home before they arrive. Every repair and cleaning is covered by our 365-Day Done Right Promise in writing: if the work fails within a year, we return and make it right at no charge, including a free second visit. That’s not a slogan. It’s on every job sheet.
We don’t compete on teaser prices. We compete on discipline. In Rancho Palos Verdes, that means understanding how Portuguese Bend ground movement separates duct seams, how coastal humidity feeds biological growth, and how wildfire ash from the Peninsula’s scrub-covered hills settles deep in systems during Santa Ana events. Local knowledge changes what “clean” actually means here.
Air Duct Inspection in Rancho Palos Verdes
Air Duct Inspection in Rancho Palos Verdes starts with a camera run through the supply and return lines because ground creep, marine-layer moisture, and wildfire contamination create failure modes that a visual register check will miss entirely. Our technician feeds a lighted scope through the trunk and branches to document seam separation, boot shear, flex kinking, moisture staining, and particulate loading. A typical inspection in Rancho Palos Verdes runs $150 – $250, and if you proceed with cleaning, we apply that toward the full system price.
What We Document
We record video of every joint, transition, and boot connection. In the slide zones, we’re specifically looking for quarter-inch gaps at seams, crushed flex at foundation shifts, and boots that have pulled free from the subfloor. You’ll see what we see. No guesswork.
Static Pressure Testing
We measure system static pressure before and after any work. A reading above 0.5 inches water column on a residential system usually indicates blockage, leakage, or both. In Rancho Palos Verdes, we’ve traced high readings back to a single pinched flex run in a hillside home’s long attic chase. Finding that saves you from replacing equipment that isn’t actually broken.
Residential Air Duct Cleaning in Rancho Palos Verdes
Residential Air Duct Cleaning in Rancho Palos Verdes means source removal under controlled negative pressure using a Nikro negative-air machine and rotary brush agitation, followed by HEPA filtration on the exhaust. A typical 2,000 – 3,000 square foot home in the Silver Spur or Miraleste neighborhoods runs $350 – $550 for full supply and return cleaning, with duct sealing and filtration upgrades quoted separately in writing before work starts.
Source Removal Process
We seal each register and create a vacuum draw at the air handler. A Rotobrush rotary brush scrubs the interior of each branch line while the Nikro unit pulls dislodged debris out of the system. Nothing gets pushed deeper. Nothing escapes into your living space. HEPA filtration on the machine exhaust captures particles down to 0.3 microns.
Post-Cleaning Verification
We run the camera again after cleaning and provide before-and-after photos of your own ducts. In Rancho Palos Verdes, where landslide damage and wildfire ash create layered contamination, this documentation proves the work happened and shows whether structural repairs are still needed. The static pressure test confirms airflow is back in spec.
Trusted Brands We Service in Rancho Palos Verdes
Our equipment roster includes Rotobrush rotary brush systems, Nikro negative-air machines, and filtration products from Honeywell, Aprilaire, and Abatement Technologies. These are the same tools commercial crews use, not hardware-store gear. For Rancho Palos Verdes homes dealing with marine-layer moisture and wildfire particulate, we stock Honeywell and Aprilaire MERV-rated media filters and Abatement Technologies HEPA filtration components locally, so upgrades happen on the same visit instead of ordering parts and rescheduling. When a Portuguese Bend homeowner needs a filtration upgrade after we’ve sealed movement-induced leaks, we can install it that day.
Common Air Duct Cleaning Problems We See in Rancho Palos Verdes Homes
- Ground creep separates duct seams. In the Portuguese Bend and Abalone Cove slide zones, slow foundation movement pulls sheet-metal trunks apart at the seams and shears boots from subfloors. A standard vacuum-only cleaning misses these leaks entirely, so conditioned air escapes into attics and crawl spaces while unfiltered air gets drawn in.
- Marine-layer moisture feeds biological growth. The cool, damp Pacific air that rolls in most mornings keeps duct interiors humid enough for mold and dust-mite colonies. Without a MERV-rated filtration upgrade and a moisture check during cleaning, the problem returns within a season.
- Long hillside runs hide crushed flex duct. The 1950s – 1970s ranch and split-level homes on multi-directional hillside lots often have flex runs stretched across awkward attic or subfloor chases. Ground shift kinks these sections flat, choking airflow to distant rooms while the blower works harder and louder.
- Wildfire ash penetrates during Santa Ana events. Dry offshore winds push smoke and fine ash from the Peninsula’s scrub-covered hills deep into duct systems through even small leaks. The particulate is oily and tenacious, requiring rotary brush agitation and negative-air extraction rather than simple vacuuming.
Pricing for Air Duct Cleaning in Rancho Palos Verdes, CA
Most full residential cleanings in Rancho Palos Verdes fall between $350 and $650 depending on system size, access difficulty, and whether we find landslide damage that needs sealing before cleaning is worthwhile. A straightforward 1,800 – 2,500 square foot ranch in Silver Spur with good attic access typically runs $350 – $450. Larger custom homes from the 1980s – 90s with multi-zone systems and tight crawlspace access can reach $550 – $650. Duct sealing with mastic, filtration upgrades, and structural repairs are quoted separately in writing before any work begins.
What moves the price: number of supply and return branches, linear footage of ductwork, accessibility (tight attics and subfloors take longer), pre-existing damage requiring repair before cleaning, and whether you want a filtration upgrade installed during the same visit. We do not quote per-vent pricing. We quote one flat price per system, agreed in writing, that does not change at the door. Call (361) 326-5060 for a free estimate.

FAQs About Air Duct Cleaning in Rancho Palos Verdes
Every three to five years for most Rancho Palos Verdes homes, though properties in the slide zones or near active brush should consider inspection every two to three years because ground movement and wildfire ash accelerate contamination and leakage. Homes with MERV-rated filtration and no structural issues can stretch toward the longer end. Call (361) 326-5060 and we’ll assess your specific system.
Yes. Slow ground creep from Portuguese Bend to Abalone Cove racks and twists foundations, pulling duct seams apart, shearing boots from subfloors, and pinching flex runs flat at foundation shifts. We got a call from a homeowner on Vanderlip Drive in Portuguese Bend whose system was barely moving air; our tech ran a camera inspection and found a flexible run to the rear bedroom pinched completely flat at a foundation shift, with the trunk line pulled open about a quarter-inch along a seam. We reconnected and re-sealed the separated joints, replaced the crushed flex run, then performed source removal under negative pressure with HEPA filtration on the supply and return ducts. The static pressure dropped back into normal range and airflow at the registers returned to spec.
The cool, damp Pacific air that rolls in most mornings keeps metal duct interiors humid enough for mold and dust-mite growth, especially in systems with existing leaks that draw unconditioned attic or crawlspace air. Without a moisture check and proper filtration upgrade during cleaning, biological contamination returns quickly. We check for active growth and recommend Honeywell or Aprilaire MERV-rated upgrades where the duct conditions warrant it.
Yes. Santa Ana wind events push fine ash and smoke from the scrub-covered hills deep into duct systems through register openings and even small leaks. The particulate is oily and adheres to duct walls. Standard vacuuming won’t remove it. Our rotary brush agitation with Nikro negative-air extraction is designed for this type of tenacious contamination. Call (361) 326-5060 for an inspection if you’ve noticed ash residue or smoky odors after recent wind events.
A camera run through the full supply and return system, static pressure testing at the air handler, and visual documentation of seam condition, boot attachment, flex integrity, moisture staining, and particulate loading. In Rancho Palos Verdes, we specifically look for landslide-induced separation at joints and crushed sections in long hillside runs. The inspection takes 45 – 90 minutes and costs $150 – $250, applied toward cleaning if you proceed. Call (361) 326-5060 to schedule.
