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.

Why Hollis Air Duct Cleaning Is Del Aire’s Preferred Air Duct Cleaning Company
We’ve been working the South Bay since 2004 as part of the Garrison Partners family, and Del Aire’s compact layout means we can usually book you within a few days, not weeks. Our technicians are background-checked, uniformed, and expected to arrive inside the quoted window, leave the site clean, and explain what they found before they pack up. That’s The Garrison Code.
Del Aire homeowners have told us the same story for years: they hired a cheap coupon service, the crew vacuumed for twenty minutes, and the gray-black dust was back on their registers before the weekend. We don’t operate that way. Every Hollis job gets a written price before work starts, a 365-Day Done Right Promise in writing, and equipment that matches what commercial crews use on much larger buildings.
Our phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No callback queues. When you’re ready to schedule, you’ll talk to someone who can actually book the appointment.
Air Duct Cleaning Services in Del Aire
Air Duct Cleaning Services in Del Aire address a problem most homeowners here don’t realize they have until they see it with their own eyes. The job involves source removal of accumulated debris from your supply and return ductwork, registers, and plenums using mechanical agitation combined with negative-air extraction. In Del Aire, that debris is typically dry, gray-black jet-exhaust soot mixed with ordinary household dust, not the mold growth you see in more humid inland climates. A typical full residential system cleaning in Del Aire runs $350 – $650 depending on system size and accessibility, with larger homes or commercial systems ranging higher. Most Del Aire homeowners benefit from cleaning every 2 – 3 years given the particulate loading here, though homes closest to the runway approaches may need more frequent attention.
Residential Duct Cleaning
Our residential work targets the complete forced-air system in your home: supply ducts, return ducts, trunk lines, and registers. We use a Rotobrush rotary brush system to mechanically agitate debris off duct walls, coupled with a Nikro negative-air machine to maintain suction and prevent soot from escaping into your living space during the process. For Del Aire homes with original 1940s-1950s flex duct in the attic, we also inspect for tears and rodent damage that can pull in additional contaminated air from the crawlspace.

Video Inspection
Before we quote and after we finish, we run a camera through your ductwork so you can see the condition yourself. In Del Aire, this usually reveals the telltale gray-black coating on return plenums that homeowners mistake for ordinary dust. The before-and-after documentation is yours to keep, and it’s part of how we prove the work was actually done.

HVAC Duct Cleaning in Del Aire
HVAC Duct Cleaning in Del Aire requires equipment and technique calibrated for dry soot, not moisture-based mold remediation. The marine-layer humidity here is mild, and rainfall is minimal, so ducts accumulate compacted dry particulates that re-entrain into the air easily if disturbed without proper containment. Our crews use HEPA filtration during every cleaning to capture ultrafine particles that standard filters miss. A typical HVAC duct cleaning for a Del Aire single-story home runs $350 – $550, with multi-system homes or commercial properties starting around $600 and scaling with square footage and system complexity.
Full System Cleaning
Full system cleaning means every component that moves air: the air handler, blower, evaporator coil if accessible, and all duct runs. In Del Aire’s raised-foundation homes, this often requires careful navigation of attic spaces with original flex duct that has become brittle with age. We don’t force equipment through fragile runs; we adapt our approach to what your specific system can handle.
Supply and Return Duct Cleaning
Return ducts in Del Aire typically show heavier loading than supply ducts because they’re pulling air directly from your living space, and that air contains jet-exhaust particulates that enter through open windows and doors. Supply ducts push conditioned air out, so they tend to stay cleaner but can still distribute whatever the returns have collected. We clean both sides of the system because partial cleaning just moves the problem around.
Trusted Brands We Service in Del Aire
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines for containment, and filtration products from Honeywell, Aprilaire, and Abatement Technologies. These are the same brands commercial HVAC contractors specify for schools and medical buildings, not the hardware-store vacuums some competitors bring to residential jobs. For Del Aire customers, this means we have the right tool to handle dry soot without spreading it, and we stock common filtration replacements so you’re not waiting on parts if your system needs an upgrade after cleaning.
Common Air Duct Cleaning Problems We See in Del Aire Homes
- Jet-exhaust soot accumulation in return plenums. The east side of Del Aire, closest to LAX’s approach paths, sees return plenums loaded with gray-black particulates that homeowners often mistake for ordinary dust until they see how fast it reaccumulates after surface cleaning.
- Rodent-damaged flex duct in attic runs. Del Aire’s 1940s-1950s housing stock frequently contains original or lightly-updated flex duct that has torn or been chewed, creating leaks that pull contaminated air from the crawlspace and worsen indoor particulate loading.
- Compacted soot in duct corners and seams. Dry soot doesn’t wash away or cling like greasy kitchen dust; it packs into corners and becomes airborne again with every HVAC cycle, which is why vacuum-only cleaning without agitation leaves the problem largely intact.
- Recontamination during improper cleaning. Competitors who skip negative-air containment and HEPA filtration can actually worsen indoor air quality by disturbing soot and letting it escape into the home during the cleaning process itself.
Pricing for Air Duct Cleaning in Del Aire, CA
We don’t do coupon teaser prices that balloon once the van is in your driveway. A typical full residential air duct cleaning in Del Aire runs $350 – $650 for a single-system home, with most single-story properties in the $400 – $500 range. Commercial systems or multi-zone residential setups start around $600 and scale based on total linear footage of ductwork and accessibility factors. Dryer vent cleaning, often booked alongside duct cleaning, typically adds $150 – $250. What moves the price: system size, number of registers, accessibility of attic and crawlspace runs, and whether we find damage that needs repair before cleaning is effective. We write the price down before any work starts, and that number does not move at the door. Estimates are free. Call (361) 326-5060.

FAQs About Air Duct Cleaning in Del Aire
You’ll likely need cleaning every 2 – 3 years instead of the 4 – 5 year interval typical in cleaner air basins. The jet-exhaust soot that settles over Del Aire is dry, ultrafine, and re-entrains easily, so it accumulates faster than ordinary household dust and requires more frequent removal to maintain air quality. Call (361) 326-5060 and we can assess your specific proximity to the flight paths and recommend an interval.
Yes, and we do it regularly. We adapt our equipment to fragile flex duct rather than forcing rigid brushes through runs that will tear, and we inspect for rodent damage and separations that are common in Del Aire’s original housing stock. If we find damage that compromises system integrity, we’ll show you on camera and quote repair before proceeding with cleaning.
Because the source is continuous: every day, new jet-exhaust particulates enter your home through open windows, doors, and the onshore breeze, and your returns pull them directly into the system. Surface cleaning of grilles doesn’t remove the reservoir of soot in your return plenum and trunk lines, which is why professional source removal with HEPA filtration is necessary to break the cycle.
We use Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines to maintain suction and prevent escape, and HEPA filtration rated to capture ultrafine particles down to 0.3 microns. This combination is specifically effective on the dry, carbon-based soot prevalent in Del Aire, which responds poorly to vacuum-only methods.
Yes. Outbuilding systems, workshops, and guest houses with independent ductwork or mini-split conversions can accumulate the same soot loading as main residences, and we clean them with the same equipment and standards. Pricing depends on system size and accessibility; call (361) 326-5060 for a specific quote.
