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.
The Hollis Air Duct Long Beach Guarantee
We’ve been cleaning air ducts in Long Beach since 2004, and we’ve built this company on a simple idea: if we do the job right the first time, we won’t have to come back. But if we don’t, we will. Every job we complete comes with the 365-Day Done Right Promise, written on paper before we leave your property. It covers the workmanship for a full year. If something we installed or sealed fails inside that window, we return and fix it at no charge. No debate, no invoice, no “that part isn’t covered.” The promise is the promise. Roy Castellanos, the owner of Hollis Air Duct Long Beach, put it in writing because verbal assurances don’t mean much when a duct seam opens six months later. We’d rather stand behind the work than argue about it.
What’s Covered
- Workmanship for 365 days. If any duct sealing, cleaning-related component, or connection we touched fails within a year, we come back and repair it at zero cost.
- Free second visit if the repair fails. The follow-up trip is included in the original promise, not negotiated after the fact.
- Written price before any work starts. The number on the page is the number on the invoice. It doesn’t move when the technician is standing in your hallway.
- Arrival inside the quoted window. We operate under The Garrison Code, which requires showing up when we said we would. If we’re running late, you’ll hear from a live person at (562) 548-7365, not a text bot.
- Site left clean. Negative-air machines pull dust out of your ducts, not into your living room. We lay down protection and we haul out anything we bring in. The job isn’t done until the area looks like we were never there.
- Equipment that does the actual job. Rotobrush rotary brush systems, Nikro negative-air machines, and filtration products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. We don’t show up with a shop vac and a flashlight.

Our Satisfaction Promise
If you’re not satisfied with the work, we make it right. That starts with a phone call to (562) 548-7365, answered by a real human being, any hour of the day. We’ll schedule a return visit. Roy Castellanos reviews every make-it-right request personally, because a complaint that goes unaddressed is just a bad review waiting to happen two years from now. The process is straightforward: we listen to what’s wrong, we put a fix on the calendar, and we don’t charge for the second trip. If the issue falls under the 365-Day Done Right Promise, the repair is free, full stop. If it’s something outside the original scope, we’ll write you a price before touching anything, so you decide with full information. Long Beach homes deal with specific conditions: salt air, summer heat pushing HVAC systems hard, and older ductwork in neighborhoods like Bixby Knolls, Belmont Heights, and Naples. We account for that. We’re not a call center. We’re local, and we’d rather face an unhappy customer than hide from one.
Licensed & Insured Backing
A guarantee is only as good as the company behind it. Hollis Air Duct Long Beach is licensed and insured, which means you’re protected on two fronts. Insurance covers your property while our team is working inside your home. Licensing means we’re accountable to the state and to the standards that govern our trade. If we failed to honor the 365-Day Done Right Promise, you’d have recourse beyond just our word. That’s the real point of the paperwork. Anyone can say they stand behind their work. A licensed, insured company has something to lose by not doing it. We’ve been part of the Garrison Partners family since 2004, and each location operates independently under The Garrison Standard: arrive inside the window, price in writing, complete the job by the book, leave the site clean. That standard is not a slogan. It’s the operating checklist for every technician who wears the Hollis Air Duct Long Beach uniform.

AfterWhy a Written Guarantee Matters in Long Beach
Duct cleaning has a reputation problem. You’ve probably heard the stories: a company advertises a low per-vent price, a technician shows up, and suddenly the bill is four times the estimate. Or the crew leaves halfway through, and nobody answers the phone when you call to ask why. We built the 365-Day Done Right Promise as a direct answer to that reputation. The price is written before work starts. It does not change at the door. The guarantee is written on the same page. If the work fails within a year, we return and fix it at no charge. And you’ll never sit on hold when you call us, because a live person picks up 24/7. Roy Castellanos, the owner, decided that answering the phone is part of the job, just like showing up on time and leaving the site clean. In a city the size of Long Beach, with everything from 1920s bungalows in California Heights to newer construction near El Dorado Park, every home has different ductwork, different issues, different histories. The guarantee doesn’t change. The work doesn’t either.
What the 365-Day Done Right Promise Does NOT Cover
We’re honest about what a workmanship guarantee can’t do. It doesn’t cover normal wear on HVAC components we never touched. It doesn’t cover damage from a roof leak that started after we left, or a rat deciding your new ductwork looks like a condo. It doesn’t cover manufacturer defects on equipment we installed but didn’t manufacture; those fall under the manufacturer’s warranty, and we’ll help you navigate that if it happens. What it covers is the work we did. If a sealed seam opens, if a connection fails, if something related to our cleaning or sealing job stops performing the way it should within 365 days, we’re back in your driveway. That distinction matters. Some companies write guarantees with enough fine print to drive a truck through. Ours is written in plain English, on one page, handed to you before we leave.
What to Do If Something Goes Wrong
Call (562) 548-7365. Tell whoever answers what’s happening. We’ll schedule a return visit at a time that works for you, inside a quoted window, same as any other job. When the technician arrives, they’ll diagnose the issue, explain what they’re seeing in plain terms, and then fix it if it falls under the promise. No charge, no arguing. If it doesn’t fall under the promise, you’ll get a written price before any work happens. You decide. That’s the whole system, and it’s worked for homeowners across Long Beach for over two decades. We’d rather keep a promise than make an excuse.
