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

Fast, Reliable Air Duct Cleaning Across Alum Rock

Air duct cleaning in Alum Rock typically runs $350 – $650 for a full residential system, and most jobs are scheduled within a week of your call. If you live in one of the post-WWII ranch tracts off Alum Rock Avenue or near the park, your ducts are likely original galvanized steel that has never been properly sealed, which means cleaning alone won’t solve the dust problem.

We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and our crews work Alum Rock regularly. Dispatch and scheduling are coordinated from our San Francisco Bay Area office, but the technicians who arrive at your door know this neighborhood: the 1950s-60s ranches with uninsulated attic trunks, the summer heat that cracks flexible connectors at the air handler, the fine dust that blows in off the Diablo Range hillsides. We don’t quote over the phone and then rewrite the number at your door. We inspect, we photograph, we write the price down, and we stick to it. Call (361) 326-5060 to book a free estimate.

Why Hollis Air Duct Cleaning Is Alum Rock’s Preferred Air Duct Cleaning Company

We’ve been in business since 2004, and our reputation in Alum Rock is built on showing up inside the window, pricing in writing, and leaving the site clean.

If the work fails within a year, we come back and make it right at no charge, including a free second visit.

Our Alum Rock customers aren’t looking for the cheapest coupon in the mail. They’re looking for a crew that won’t track dust through the living room, won’t claim eight vents and then charge for twelve, and won’t disappear when the job goes sideways. We use professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, and we explain what we’re doing while we do it. The price is written down before any work starts, and it does not move at the door.

Air Duct Cleaning Services in Alum Rock

Air Duct Cleaning Services in Alum Rock start with understanding what kind of house you have. Most of this neighborhood was built fast in the 1950s and 1960s for returning veterans and factory workers, and the ductwork reflects that: rigid galvanized steel trunks, often uninsulated, run through attics that hit 95°F or higher from June through September. Decades of seismic movement, thermal expansion, and vibration from the blower motor have loosened joints and separated seams. A proper cleaning here isn’t just a vacuum job. It’s a camera inspection, a negative-pressure extraction with rotary brush agitation, and usually duct sealing with mastic to close the gaps that draw in hillside dust.

A typical residential Air Duct Cleaning in Alum Rock runs $350 – $650 depending on system size and accessibility. Homes with crawl space returns or attic-mounted air handlers take longer. We don’t price per vent because that’s how the bait-and-switch works. We price per system, agreed in writing before we start.

Residential Duct Cleaning

Our residential work covers single-family ranches, duplexes, and the small apartment buildings common near Alum Rock Expressway. We clean supply ducts, return ducts, and the trunk lines that connect them, using Rotobrush rotary systems to knock debris loose and Nikro negative-air machines to pull it out without blowing it into your rooms. Afterward, we show you before-and-after photos from our camera inspection. If we find separated joints or crushed runs, we explain the sealing work and price it separately, in writing.

Commercial Duct Cleaning

Alum Rock’s commercial buildings, the small retail strips along White Road and the older office spaces near King Road, need scheduled cleaning that doesn’t shut down business hours. We work evenings and weekends, use contained negative-air methods to protect occupied spaces, and provide written documentation for property managers and insurance carriers.

HVAC Duct Cleaning in Alum Rock

HVAC Duct Cleaning in Alum Rock means dealing with systems that were never designed for modern cooling loads. The 1950s-60s ranches here have undersized returns, original galvanized trunks that have never been sealed, and flexible connectors at the air handler that crack under summer attic heat. We see this pattern every June after the first serious heat wave: calls from homeowners near Alum Rock Park who notice weak airflow, dust buildup, or a blower motor that sounds like it’s working too hard.

The cost for HVAC Duct Cleaning on a typical Alum Rock ranch runs $400 – $750 if sealing work is needed, $350 – $550 for cleaning alone. We don’t know which you need until we inspect. That’s why estimates are free.

Video Inspection and Diagnosis

Every HVAC Duct Cleaning job starts with a camera run. We feed a scope through the supply and return trunks and show you what we see: separated joints, crushed runs from someone stepping on the duct in the attic, cracks in the flexible connector, or accumulation that has built up because the system was never properly sealed. The video drives the estimate. No video, no guesswork, no price that changes after we start.

Full System Cleaning with Sealing

On most Alum Rock homes, cleaning without sealing is a temporary fix. We apply mastic sealant to accessible joints and recommend metal-backed tape or duct sealing mastic for larger gaps. The goal is to drop the static pressure, stop the infiltration of attic dust and hillside particulate, and let the blower motor work the way it was designed to. We explain every step before we do it, and we photograph the sealed joints for your records.

Trusted Brands We Service in Alum Rock

Our equipment roster includes Rotobrush rotary brush systems for agitation cleaning, Nikro negative-air machines for contained extraction, and filtration products from Aprilaire and Guardsman. We don’t use hardware-store shop vacs or consumer-grade duct cleaning attachments. The Rotobrush system we run in Alum Rock attics is the same tool commercial crews use in hospitals and schools, and the Aprilaire media filters we can install after cleaning are rated for the fine particulate that blows in off the Diablo Range. We stock common parts and filter sizes locally, so if your air handler needs a new flexible connector or a return plenum modification, we’re not ordering parts and making you wait.

Common Air Duct Cleaning Problems We See in Alum Rock Homes

• Separated galvanized trunk joints. The original steel ductwork in 1950s-60s Alum Rock ranches was assembled with slip joints and drive cleats, not sealed seams. Decades of seismic movement and thermal cycling have opened gaps that draw in hot, dusty attic air. We find these with a camera, clean behind them, and seal them with mastic so they stay closed.
• Cracked flexible connectors at the air handler. The rubberized connector between your furnace or air handler and the rigid trunk line sits in the hottest part of the attic. After a 95°F week in June, the material hardens and splits. We replace these during cleaning jobs when we find them, and we show you the crack on camera before we quote the repair.
• Undersized returns starving the system. A 1,200-square-foot ranch built in 1960 might have a single 14-inch return duct. Modern equipment needs more airflow. Homeowners blame “dirty ducts” when the real problem is a return that was never sized for the current system. We measure static pressure and airflow before we clean, and we tell you if the duct is the wrong size.
• Moisture and mold after winter rains. Alum Rock’s winter rains can leak into attics through old vent flashing or rotted fascia, and uninsulated galvanized ducts collect condensation when cold attic air meets warm supply air. We check for water staining and microbial growth during inspection, and we recommend remediation before cleaning if we find active mold.
