Air Duct Cleaning in Pomona - One Flat Price, Before-and-After Photos

Fast, Reliable Air Duct Cleaning Across Pomona

Air duct cleaning in Pomona typically runs $350 – $650 for a full residential system, and most jobs are scheduled within a few days of your call. If your home was built before 1980, there’s a good chance the original galvanized or early flex ductwork has never been properly sealed, and that’s where the real problem lives.

Call (361) 326-5060

We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and our crews work Pomona regularly – from the Lincoln Park stucco tracts to the apartment conversions near Cal Poly Pomona. Dispatch and scheduling are coordinated from our Los Angeles office, but the techs who arrive at your door know this city’s housing stock and its particular headaches. They know that after a Santa Ana wind event, the return grilles in homes along the I-10 corridor and near the LA County Fairplex collect a fine, reddish-brown silica dust that a shop vac won’t touch. They also know that cleaning ducts without inspecting for disconnected or crushed runs is half a job. Call us at (361) 326-5060 for a free estimate, or read on to see what we actually find in Pomona attics and crawl spaces.

Why Hollis Air Duct Cleaning Is Pomona’s Preferred Air Duct Cleaning Company

We’ve been in business since 2004, and our Air Duct Cleaning team has worked enough Pomona homes to know the patterns. The pre-1980 single-story stucco houses in Wilton Heights and the citrus-era cottages near downtown share common duct problems: original round metal runs that have separated at the seams, early Mylar flex that has collapsed in the attic heat, and return systems that pull in dust from the crawl space because the boot was never sealed.

Pomona customers tell us they chose us because we show up inside the quoted window, price the job in writing before we touch anything, and leave the site clean. That’s The Garrison Standard, and it applies to every independently owned Hollis location. Our technicians are background-checked and uniformed – you know who’s walking into your home before they arrive. And our phones are answered by a live person 24 hours a day, seven days a week. No voicemail loops. No callback queues.

Every job carries our 365-Day Done Right Promise in writing: if the work fails within a year, we come back and make it right at no charge, including a free second visit. Competitors in this trade rarely put that in writing.

Ductwork Cleaning in Pomona

Ductwork Cleaning in Pomona means more than pushing a brush through a tube. In this city, it means dealing with decades of accumulated debris in systems that were often undersized from the start, then subjected to 8 – 10 months of annual runtime thanks to Pomona’s inland heat and Santa Ana wind cycles.

Our process starts with a camera inspection. We need to see what we’re dealing with before we quote a price. In a typical Pomona home built between 1950 and 1975, we often find supply trunks coated with a gray-brown mat of dust, skin cells, and construction debris; return ducts that have pulled in attic insulation through a disconnected boot; and flex runs that have been crushed by a storage box or gnawed by rodents. We price the full job in writing before we start. No per-vent add-ons. No surprises at the door.

Rotary Brush and Negative-Pressure Source Removal

We use Rotobrush rotary brush systems for mechanical agitation inside the duct, paired with Nikro negative-air machines that pull loosened debris out of your home entirely rather than redistributing it. For Pomona’s heavier dust loads, we often deploy HEPA-filtered Abatement Technologies units that capture particles down to 0.3 microns. This matters here. The fine silica dust that Santa Ana winds carry from the San Gabriels is abrasive and persistent. A shop vac or a compressed-air wand just stirs it up.

Sealing What We Find

Cleaning without sealing is temporary. In Pomona’s original galvanized systems, we regularly find separated joints, missing dampers, and boots that were never mastic-sealed to the drywall. We reconnect what we can and seal with mastic and mesh where the metal has failed. If a flex run is crushed or rodent-damaged beyond repair, we tell you exactly what it costs to replace it before we proceed.

Air Duct Inspection in Pomona

Air Duct Inspection in Pomona is the step most homeowners skip, and it’s the step that determines whether cleaning will actually solve anything. We camera-inspect the full supply and return system before we quote. In this city’s housing stock, we find something worth addressing on better than half the inspections we perform.

The inspection takes 45 – 90 minutes depending on system size. We feed a lighted camera through every accessible trunk and branch, recording what we see. You watch the monitor with us. In a 1962 ranch near Lincoln Park last month, we found a galvanized return trunk that had rusted through at the bottom, pulling crawl-space air directly into the furnace. The homeowner had paid for two “cleanings” elsewhere that never addressed the actual problem. Our written report included photos, a marked-up diagram of the system, and line-item pricing for cleaning, sealing, and the trunk repair.

When to Schedule an Inspection

Call for an inspection if you’ve noticed uneven temperatures between rooms, a spike in your energy bill, visible dust accumulation at registers, or a musty smell when the system runs. In Pomona’s older homes, these symptoms usually point to disconnected ducts, blocked returns, or collapsed flex runs rather than dirty ducts alone. The inspection finds the root cause so you’re not paying for work you don’t need.

What the Inspection Costs

A full camera inspection in Pomona runs $150 – $250, applied toward your cleaning or sealing job if you proceed. We do not charge for estimates, and we do not use the inspection as a pressure tactic. You get the video, the diagram, and the written price. Decide on your own timeline.

Trusted Brands We Service in Pomona

Our equipment roster includes Rotobrush rotary brush systems, Nikro negative-air machines, and HEPA filtration from Abatement Technologies. For homes with whole-house air cleaners or upgraded filtration, we stock and service Aprilaire media filters and Guardsman UV systems. These are the same tools and components commercial crews use in hospitals and schools, sized for residential application. We carry common Aprilaire and Honeywell filter sizes on our Pomona service vehicles, so if your inspection reveals a clogged media filter or failed UV bulb, we can often replace it same visit rather than ordering parts and rescheduling.

Common Air Duct Cleaning Problems We See in Pomona Homes

• Disconnected or crushed original flex runs. The early Mylar flex duct installed in Pomona’s 1960s and 1970s tracts becomes brittle in attic heat. We’ve found runs completely separated from the trunk, blowing conditioned air into the insulation. Cleaning without reconnecting them just polishes the debris inside a duct that isn’t delivering air.
• Reddish-brown silica dust after Santa Ana events. The fine dust that coats Pomona return grilles each fall comes from the San Gabriel Mountains and the I-10 corridor. It’s silica-heavy, abrasive, and resists light cleaning. Agitation with rotary brushes plus negative-pressure extraction is the only method that removes it without pushing it deeper into the system.
• Unsealed boots and plenums pulling in crawl-space air. Original Pomona ductwork was rarely sealed at the connection points. Your furnace works fine, but it’s heating and cooling air from under the house – along with whatever’s down there. We seal with mastic and mesh, not tape that dries and fails.
• Undersized post-1980 infill systems recirculating stale air. Apartment conversions and tight infill homes in Pomona were ducted for open-window cooling. Sealed up and air-conditioned now, they run negative pressure and trap particulates. Cleaning helps, but adding return capacity or upgrading filtration is often the real fix.
