Air Duct Cleaning in South San Gabriel - One Flat Price, Before-and-After Photos

Fast, Reliable Air Duct Cleaning Across South San Gabriel

Air duct cleaning in South San Gabriel typically runs $350 – $650 for a full residential system and is usually scheduled within a few business days. We’re Hollis Air Duct Cleaning, and we’ve been sending crews to the San Gabriel Valley since 2004. Our dispatch team operates from our Los Angeles office, but the trucks that roll up to homes near San Gabriel Boulevard and Mission Drive are stocked and routed for this specific basin. We know the difference between a 1962 ranch on Del Mar Avenue with original galvanized steel ductwork and a newer build off Las Tunas Drive with flex runs that have started to sag in the attic heat. That matters because the cleaning method, the access points, and what we’re likely to find inside change completely. If you’re seeing dust blow back from your vents after the Santa Ana winds pass through, or your allergies spike every August when the smog inverts and sits in this valley, call us at (361) 326-5060. We’ll give you a written price before any work starts, and we back every job with our 365-Day Done Right Promise.

Why Hollis Air Duct Cleaning Is South San Gabriel’s Preferred Air Duct Cleaning Company

We’ve built our reputation in South San Gabriel on showing up when we said we would, pricing in writing before we touch anything, and leaving the site clean. That shouldn’t be remarkable in this trade, but it is. Our Air Duct Cleaning team serves the full South San Gabriel area, from the older tracts near the Whittier Narrows Recreation Area to the residential pockets closer to Alhambra’s border.

Our technicians are background-checked and uniformed. You get a name and photo before anyone arrives at your door. That’s The Garrison Code in action, not a bullet point on a brochure.

Phones get answered by a live person, 24 hours a day, 7 days a week. No voicemail loops, no “leave a message and we’ll call back Monday.” When you’re trying to schedule around work or figure out if that burning smell from your vents is urgent, you talk to a human.

And our 365-Day Done Right Promise covers every repair in writing. If the work fails within a year, we come back and make it right at no charge, including a free second visit. Most competitors in the San Gabriel Valley won’t put that on paper.

Air Duct Inspection in South San Gabriel

Air Duct Inspection in South San Gabriel starts with a technician feeding a lighted video scope through your supply and return runs, looking for buildup levels, disconnected joints, and the kind of grit that blows in from the hills during Santa Ana season. Most homeowners here need one before buying a 1950s-70s tract home with unknown maintenance history, or when they notice uneven airflow, musty odors, or visible debris around vent covers. A standalone inspection runs $125 – $195 in this market, and we apply that full amount toward your cleaning if you move forward.

What the Camera Reveals

The video feed shows you exactly what’s inside your ducts in real time. In South San Gabriel homes, we regularly find fine ash and dust packed into low spots where flex duct has sagged in the attic heat, or corrosion inside original galvanized steel runs that have been collecting condensation for forty years. You see it with your own eyes, not ours.

Inspection Report and Written Quote

After the scope, you get a written report with photo stills and a flat price for any recommended work. No per-vent pricing, no add-ons once the technician is inside. The price we write down is the price you pay.

Residential Air Duct Cleaning in South San Gabriel

Residential Air Duct Cleaning in South San Gabriel means pulling decades of accumulated dust, smog particles, and Santa Ana grit out of duct systems that were never designed for the air quality this valley sees today. Our crews use Rotobrush rotary brush systems for mechanical agitation inside the runs, paired with Nikro negative-air machines that maintain suction at the trunk line so debris doesn’t escape into your living space. A typical single-story ranch with 8 – 12 vents runs $350 – $550; larger homes or systems with multiple returns and heavy buildup range $500 – $650. We also handle Dryer Vent Cleaning in South San Gabriel during the same visit, which saves you a trip charge and catches a fire hazard most homeowners overlook.

Supply and Return Cleaning

Supply ducts push conditioned air into your rooms; returns pull it back to the air handler. Both sides need attention, but returns usually hold more buildup because they’re the intake point for all that valley dust. We clean both completely, not just the vents you can see from the hallway.

Post-Cleaning Verification

After agitation and extraction, we run the video scope again so you can see the difference. Before-and-after footage of your own ducts, not stock photos. That’s how you know the work was actually done, and done thoroughly.

Trusted Brands We Service in South San Gabriel

We clean and service duct systems connected to equipment from every major manufacturer, and we stock filtration upgrades that actually fit the older air handlers common in this area. Our trucks carry Aprilaire media filters, Abatement Technologies HEPA filtration products, and Guardsman antimicrobial treatments for duct interiors. If your 1970s ranch still runs the original furnace cabinet, we likely have the adapter kit to upgrade your filtration without replacing the whole system. For homes with newer equipment, we match the filter spec to what the manufacturer requires, not whatever’s on sale at the hardware store. Parts and filters are on the truck, so most upgrades happen same visit, not after a two-week order delay.

Common Air Duct Cleaning Problems We See in South San Gabriel Homes

• Original flex duct collapsing in attic heat. The 1950s-70s housing stock near Del Mar Avenue and surrounding streets used flexible duct that degrades after decades in San Gabriel Valley attics. We find runs that have completely detached from boots, dumping conditioned air into insulation instead of bedrooms.
• Smog and particulate infiltration through leaky returns. South San Gabriel sits in the basin where the 10 and 710 freeways feed constant traffic emissions. When return ducts pull air from wall cavities or attics instead of sealed return paths, they’re drawing that outdoor pollution straight into your circulation.
• Santa Ana ash and dust packed into low duct sections. During dry, windy months, fine grit from the surrounding San Gabriel Mountains infiltrates through every attic gap and vent cover gap. Homeowners often mistake this for ordinary household dust, but it’s sharper, more abrasive, and harder on blower motors.
• Disconnected galvanized steel joints behind drywall. Original metal duct in these ranch homes was joined with tape and screws that corrode over time. We find separations hidden in walls where conditioned air has been leaking for years, driving up utility bills and letting unfiltered attic air mix with supply air.
