Frequently Asked Questions

Most single-family homes in Long Beach take between two and four hours from setup to final walkthrough. Larger homes with multiple HVAC systems or significant buildup can stretch to half a day. We work inside a scheduled window and we arrive inside the window we gave you. Roy Castellanos runs the local team with a simple rule: show up when you said you would, do the job by the book, and leave the site cleaner than you found it.

We connect a high-powered vacuum system to your ductwork to create negative pressure, then agitate the interior walls of the ducts to dislodge dust, pet hair, and debris. Each vent and return register is cleaned individually. We also clean the supply and return plenums. Afterward, we walk you through the system and show before and after photos so you can verify the work with your own eyes. The whole point is cleaner air moving through your home, from the vents on out.

Yes, dryer vent cleaning is a service we offer alongside air duct cleaning in Long Beach. Lint buildup in dryer vents is a fire risk and reduces dryer efficiency, and with the salt-heavy coastal air here, lint tends to clump and stick more stubbornly. We'll inspect and clean the full dryer vent run. It's a straightforward add-on that many homeowners book at the same time as their duct cleaning.

It can reduce the amount of dust, pollen, and pet dander recirculating through your home, which matters in Long Beach where windows stay open much of the year and coastal allergens drift in. Duct cleaning removes what's already settled in the system, but it's not a cure for allergies. Pairing clean ducts with regular filter changes and a clean home environment gives you the best result. Many of our Long Beach customers notice less dust settling on furniture within a few weeks of a cleaning.

Yes, someone over 18 typically needs to be present for access and to approve the work area. We'll walk the property with you, confirm the scope, and show you the finished job. It's your home and your air; being there means you see the before and after with your own eyes. Our Long Beach team works clean, with drop cloths and shoe covers as standard.

Not messy at all when it's done right. Our equipment creates a sealed negative-pressure system that pulls debris directly into the collection unit, not into your living room. We lay down protection around work areas and clean up thoroughly before we leave. Leaving the site clean and squared away is part of The Garrison Code we work under, not a courtesy.

We run professional-grade equipment built for the trade, including Abatement Technologies negative air machines and Rotobrush agitation tools. These aren't consumer-grade shop vacs; they're engineered for whole-home duct systems and the kind of caked-on particulate we see in Long Beach homes near the coast. The tools matter because they determine whether dust is actually removed or just loosened and recirculated.

We generally recommend high-quality pleated filters with a good MERV rating for Long Beach homes, and Aprilaire filters are a solid option we're happy to point you toward. The right filter depends on your system's airflow capacity, whether you have pets, and how close you are to the coast. A filter that's too restrictive can strain your blower. We'll give you a straight answer for your specific setup when we're in the home.

We can remove surface contamination and debris, but active mold growth inside ductwork is a different scope of work. If we find evidence of mold or standing moisture during an inspection in your Long Beach home, we'll tell you plainly and recommend the right next step, which may involve a remediation specialist. Coastal humidity makes Long Beach homes more prone to moisture issues, so we check for this on every job. Honesty about what we can and can't do is part of working by the book.

Every pro working under the Hollis name is required to hold the license and insurance their state requires. We work to The Garrison Standard, which means accountability for every job we take in Long Beach. You're welcome to ask about credentials when you call, and a straight answer is what you'll get. No vague reassurances, just the facts of how we operate.

Our Long Beach branch is led by Roy Castellanos, who runs the local team with a disciplined, no-nonsense approach. We're part of the Garrison Partners family of brands, which means we're an independent local business operating to a shared standard: arrive inside the window we gave, price in writing before work starts, do the job by the book, and stand behind the work for a full year. The brand behind us has been in this trade since 2004.

The people who work under our name are held to the standards our network requires, including proper licensing and insurance for the work they perform. We understand you're letting a crew into your home, and we take that seriously. The best proof is how the job runs: we show up on time, we communicate clearly, and we leave your Long Beach home clean. Ask us anything specific when you call (562) 548-7365.

Air duct cleaning is a scheduled service, not an emergency response. What we offer is reliability: we arrive inside the window we gave you, and we don't drift or no-show. Our Long Beach branch operates Monday through Friday from 7:00 AM to 7:00 PM, and Sunday from 7:00 AM to 7:00 PM. Call (562) 548-7365 to book a time that actually works for your schedule.

We're open Monday through Friday from 7:00 AM to 7:00 PM, and Sunday from 7:00 AM to 7:00 PM. We're closed on Saturday. We book specific appointment windows, not vague "sometime between 8 and 5" promises. Call (562) 548-7365 and we'll find a slot that works.

It depends on our current schedule, but we'll tell you straight what's available when you call. We serve Long Beach and the surrounding communities including Huntington Beach, Garden Grove, San Pedro, Carson, Westminster, Buena Park, Lakewood, Cypress, Downey, Norwalk, and Bellflower. Plan ahead when you can, and we'll lock in a specific window that works.

Every job is covered by The Garrison Standard: if the work fails within a full year, we come back and make it right at no charge. That's the guarantee in writing, not a verbal promise. It covers the cleaning work we performed. If something isn't right after we leave your Long Beach home, call us and we'll address it. That's what standing behind the work means.

You'll see it. We show before and after photos of your own ducts, taken during the job with the same camera positions. You'll see the dust, pet hair, and debris that came out of the system. Roy Castellanos and the local team don't ask you to take it on faith; we show you the evidence. It's the same standard we'd want for our own homes in Long Beach.

Most Long Beach homes benefit from a full cleaning every three to five years, but that shifts with conditions. Homes with pets, recent renovations, smokers, or coastal exposure may need it more often. If you're near the water, salt air and humidity contribute to faster particulate buildup. We'll give you an honest recommendation for your specific home after an inspection, not a one-size-fits-all calendar. Call (562) 548-7365 to talk through your situation.

Call us. We stand behind the work for a full year under The Garrison Standard, and if something didn't get done right, we come back and make it right at no charge. Our Long Beach customers don't get a runaround; they get a straight answer and a scheduled return visit. That's the whole reason we put the guarantee in writing.
