What Pasadena Homeowners Say About Hollis Air Duct Pasadena
Reviews matter because ductwork is the one system in your home you can’t easily inspect yourself. You can see a cracked tile or a leaking faucet. You can’t see what’s sitting in the return plenum. That’s why we encourage every Pasadena customer to read what their neighbors have said after we’ve pulled the registers, run the negative-air machines, and showed them photos of what came out. Roy Castellanos built this company in 2004 on a simple idea: do the work by the book, put the price in writing, and leave the site cleaner than you found it. The reviews below reflect that.
Recent Reviews
“Our house near Caltech had a musty smell every time the AC kicked on. Hollis came out, found the return duct pulling air from a crawlspace gap, sealed it with mastic, and cleaned every branch line. The smell was gone by that night. They showed me photos of the coils before and after. No upsell, no drama.”

“Two kids, two dogs, and fifteen years of dust in a 1940s bungalow off Washington Boulevard. The Rotobrush system they ran through the supply lines pulled out material I didn’t want to identify. The written price matched the final invoice to the penny. That’s what sold me before they even started.”

“I called three companies. Two gave me a per-vent price over the phone. Hollis gave me one flat price for the whole system, in writing, before anyone stepped inside. Then they arrived inside the window, wore shoe covers, and finished in about four hours. The negative-air machine they used kept dust from blowing back into the living room.”

“After a kitchen remodel near the Rose Bowl, drywall dust got pulled into every supply vent in the house. Hollis cleaned all the lines, replaced the filter media, and left the site spotless. They even wiped down the registers. Roy runs a tight operation.”

“My parents live in a condo off Lake Avenue and their dryer was taking two cycles to dry a load. Hollis cleaned the vent run and found a bird nest near the exterior cap. Removed it, cleaned the line, checked airflow with a meter, and showed me the reading. $210 and the dryer works like new. The 365-day guarantee is in writing, not a sales pitch.”

“I was skeptical because this industry has a reputation for bait-and-switch pricing. Hollis quoted $485 for a full duct cleaning of a 1,600-square-foot home in Hastings Ranch. The technician checked every register, ran the Rotobrush through all supply and return lines, and used a Nikro negative-air machine the whole time. Final bill: $485. I kept the written quote as proof.”

Why Customers Trust Us
Trust in this trade is earned through specifics, not adjectives. Every Hollis Air Duct Pasadena technician arrives inside the quoted window, in uniform, and background-checked before they ever step onto your property. The price is written down before work starts and it does not move at the door. No per-vent games, no surprise line items, no pressure to add services you don’t need. If the work fails within a year, the 365-Day Done Right Promise means we come back and fix it at no charge, including a free second visit. That’s not a marketing slogan. It’s stamped on every invoice. The equipment matters too: Rotobrush rotary brush systems, Nikro negative-air machines, and filtration products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. These are the same tools commercial crews use, not hardware-store knockoffs. Roy Castellanos has been running Hollis Air Duct in Pasadena since 2004, and the reviews above reflect what happens when a crew follows The Garrison Code: arrive inside the window, price in writing, complete the job by the book, and leave the site clean. If you want an honest assessment of your ductwork in Pasadena, call (626) 469-5477. We’ll tell you what needs doing, what doesn’t, and what it costs. In writing.
