The Hollis Air Duct Henderson Guarantee
When Roy Castellanos started Hollis Air Duct Henderson, he made one rule: if we wouldn’t put it in writing, we wouldn’t promise it. That’s why every job we do in Henderson comes with a written price before work starts and the 365-Day Done Right Promise behind it. Here’s what that means for you: if the work we do fails within a full year, we come back and make it right at no charge. No arguing, no pro-rating, no “that’s normal wear.” We fix it. That’s the whole guarantee, and it’s been that way since 2004.
What’s Covered
The 365-Day Done Right Promise isn’t vague language on a brochure. It covers specific commitments we make on every Henderson job:
- Workmanship for a full year. If any duct cleaning, dryer vent cleaning, or duct sealing work we perform fails within 365 days, we return and correct it at no charge.
- A free second visit, included. If the repair fails, the follow-up call is already covered. You don’t ask for it, you don’t negotiate for it, and you don’t pay for it.
- Written pricing before work begins. The number we quote is the number you pay. It does not change once the technician is inside your home.
- Clean site, every time. We leave your Henderson home the way we found it: floors protected, fixtures covered, debris hauled off, and vents wiped down.
- Background-checked, uniformed technicians. You know who’s walking into your home before they arrive, and they’re accountable to the Garrison Code on every job.
- Professional-grade equipment. Rotobrush rotary brush systems, Nikro negative-air machines, and filtration products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. This is commercial tooling, not hardware-store gear.

Our Satisfaction Promise
If you’re not satisfied with the work we did in your Henderson home, you call us. That call goes to a live person, not a voicemail loop, because we answer phones 24 hours a day, 7 days a week. We listen, we look at what happened, and we make it right. Usually that means sending a technician back out, often at no charge under the 365-Day Done Right Promise. If the issue falls outside the warranty window, we’ll still tell you exactly what we can do and what it costs before anyone gets in the van.
We don’t make you chase us. We don’t hide behind fine print. Roy’s position is simple: if we did the work and it’s not holding up, that’s on us. The promise is written on every job ticket so there’s no confusion about what’s covered and for how long. One year. In writing. Done.

AfterLicensed & Insured Backing
A guarantee is only as good as the company behind it. Hollis Air Duct Henderson is licensed and insured in Nevada, and we carry the coverage that protects your home while we’re in it. If a technician damages property during a cleaning or sealing job, insurance handles it. That’s not a marketing line; it’s why we keep our credentials current and why we never send an uninsured crew to a Henderson address.
Our technicians are background-checked and uniformed. They arrive inside the quoted window, the price is already in writing, and the job gets done by the book. That’s the Garrison Standard: show up on time, honor the written quote, finish the job, leave the site clean. If any of that doesn’t happen, the 365-Day Done Right Promise is how we make it right. Call (775) 383-5847 and ask us anything about the guarantee before you book. Roy will tell you exactly what it covers, what it doesn’t, and what happens if something goes wrong.
Why the Guarantee Matters in Henderson
Henderson’s dry desert climate puts its own strain on ductwork. Dust from the Mojave, fine silt that works its way through vents, and HVAC systems running hard through triple-digit summers mean your ducts collect material faster than homes in wetter climates. We’ve been cleaning ducts in Henderson since 2004, and we’ve seen what happens when work isn’t backed: homeowners pay twice for the same job because the first company won’t answer the phone.
Our promise eliminates that risk. If the cleaning doesn’t hold, if the sealing fails, if the dryer vent clogs again faster than it should, you call us and we return. You don’t pay for the second visit. That’s not a perk; it’s the way the business was built. Roy Castellanos puts his name on every job we do in Henderson, and the guarantee is how he stands behind it.
Common Questions About Our Guarantee
How long does the 365-Day Done Right Promise last?
The workmanship warranty runs for 365 days from the date of service. If the duct cleaning, dryer vent cleaning, or duct sealing work we performed fails within that window, we return and fix it at no charge. After the year is up, call us anyway: we’ll troubleshoot over the phone and tell you exactly what a repair would cost before we schedule anything. Call (775) 383-5847 to talk through what’s covered.
What happens if the repair fails a second time?
You call us again. The 365-Day Done Right Promise isn’t a one-shot deal. If the work isn’t holding, we keep working it until it’s right, and you don’t pay for the return visits during the warranty period. That’s the point of putting it in writing: the guarantee has teeth. Call (775) 383-5847 and we’ll get someone out.
Does the written price really not change?
Correct. The quote you get before work starts is the price you pay when the job is done. If we find something during the job that needs attention, we stop and show you, and you approve any change in writing before we proceed. No surprises on the invoice. If you have a question about a quote you received, call (775) 383-5847 and Roy will walk you through it.
Are you licensed and insured in Henderson?
Yes. Hollis Air Duct Henderson is licensed and insured in Nevada, and we carry the coverage that protects your home during our work. Every technician is background-checked and uniformed, so you know who’s in your house before they arrive. Call (775) 383-5847 if you’d like to verify anything before booking.
What if I’m not happy with the job for a reason that’s not a mechanical failure?
Call us. If we left a mess, if the technician was late, if something about the job bothers you, we want to hear it and we’ll make it right. The 365-Day Done Right Promise covers the work, and the Garrison Code covers how we behave while doing it. You can reach a live person at (775) 383-5847 any time, day or night.
