Our Guarantee & Warranty - Hollis Air Duct Hempstead

The Hollis Air Duct Hempstead Guarantee

We’ve been cleaning ducts in Hempstead since 2004. That’s more than two decades of pulling clumps of lint and dust from return plenums in homes across the village, from the older colonials near Hofstra to the newer developments by Hempstead Turnpike. What has kept us in business this long isn’t clever marketing. It’s a guarantee that’s simple enough to fit on the bottom of every invoice we leave behind: the price is written down before we start, the work is done by the book, and if something fails within a year, we come back and make it right without charging you a dime. That is the 365-Day Done Right Promise, and the owner, Roy Castellanos, puts his name on it for every job that leaves our shop.

What’s Covered

Our guarantee isn’t a paragraph of fine print. Here’s exactly what we stand behind on every air duct cleaning, dryer vent cleaning, and duct sealing job in Hempstead:

• Workmanship for a full year. If any part of the work we performed fails or doesn’t hold up within 365 days, Hollis Air Duct Hempstead returns and fixes it at no charge. No prorated anything. No arguing about when it started. You call, we schedule the return visit, we make it right.
• A free second visit if the repair fails. This isn’t a gesture. It’s written into the guarantee. If you call us back because something we fixed didn’t stay fixed, the second visit is free. Included, not negotiated.
• Your ducts are left cleaner than we found them. The whole point of the job is removing buildup, not relocating it. We run negative-air machines during the cleaning so dust and debris are pulled out of your system, not pushed into your living room. The equipment we use, including Rotobrush rotary brush systems and Nikro negative-air machines, is professional-grade gear from brands commercial crews run, not something you’d find in a hardware-store rental aisle.
• Arrival inside the quoted window. The Garrison Standard requires it. When we give you a time, that’s when the van shows up. Background-checked, uniformed technicians arrive ready to work, explain what they’re doing in plain terms, and knock out the job without treating your home like a science lab.
• Honest, written pricing before anything starts. You get the price in writing before a single tool comes off the truck. That number does not move at the door. No estimates that balloon once the technician is inside, no surprise line items for “difficult access” or “extra vents.” The price you agree to is the price you pay.
• Site left clean. The Garrison Standard says we leave the site the way we’d want our own house left. Boot covers on, drop cloths down, all debris bagged and removed. If you can tell we were there except for the cleaner air, we did our job.

Our Satisfaction Promise

If you’re not satisfied with the work, you call us. A live person answers, not a voicemail loop. We don’t route you to a call center or tell you to fill out a form online. You’ll speak to someone who can actually schedule a return trip. Within that year, if something we repaired or sealed fails again, the second visit is free. We come back, diagnose what happened, and fix it. No invoices. No “well, this is a different problem” explanation. If we touched it, we stand behind it. Roy Castellanos, the owner of Hollis Air Duct Hempstead, has been doing this since 2004, and the guarantee has been the same the whole time: if it’s not done right, we make it right, in writing, on every job. That’s not a marketing promise. It’s how we’ve kept our name in good standing across Hempstead for years.

Licensed & Insured Backing

A guarantee only matters if the company behind it can actually be held accountable. That’s where licensing and insurance come in. Hempstead homeowners don’t need to take our word for it; they need to know we operate like a real business, properly documented and insured. We are licensed and insured for the work we do. If a technician is in your home and something gets damaged, our insurance covers it. That’s the part of the guarantee you hope never to need, but it’s the reason we carry it. A legitimate company in Hempstead doesn’t show up to a house without that backing. We’ve been operating in this village since 2004, and we don’t plan on being a fly-by-night operation. The paperwork is real, and Roy Castellanos stands behind every line of it.

What the 365-Day Done Right Promise Actually Looks Like

Let’s say we clean a dryer vent in a Hempstead home off Peninsula Boulevard. Three months later, the homeowner notices the dryer taking longer to dry clothes again. They call the number on the invoice, (516) 559-4917. A live person answers. We look up the job, see it’s within the 365-day window, and schedule a return visit. The technician comes back, inspects the vent line, and finds the issue was something we missed on the first pass. The second visit is free. No invoice. That’s the promise, and it applies the same way to air duct cleaning jobs on Harvard Street and duct sealing work near Baldwin. If it fails within a year, it’s on us. Not you.

Why the Guarantee Is Written, Not Verbal

Plenty of contractors say they’ll stand behind their work. Few write it down. We do. Every Hollis Air Duct Hempstead job comes with the 365-Day Done Right Promise in writing. You get a document that spells out what’s covered and for how long. That matters because verbal promises disappear the moment there’s a dispute. A written one is a contract. It tells you we’re confident enough in our own work to put it on paper before we’ve even finished the job. The Garrison Standard that every independently owned Hollis location operates under requires pricing in writing, arrival in the quoted window, and the job done by the book. The guarantee is just the final piece: if we miss the mark, we make it right. Free. Within a year. That’s the deal.

Questions Homeowners Ask About Our Guarantee

Does the warranty cost extra?

No. The 365-Day Done Right Promise is included on every job. You won’t see a line item for it. It’s simply how we do business in Hempstead.

What counts as a “failure”?

Anything related to the work we performed. If a duct joint we sealed reopens, if a dryer vent we cleaned clogs again within a year, if something we fixed breaks again. If we touched it, we own it. Call us at (516) 559-4917 and we’ll get it sorted.

How fast can you come back?

We schedule the return visit as quickly as our calendar allows. You won’t be waiting weeks with a clogged dryer vent. A live person answers when you call, and we get you back on the schedule.

Why do some companies charge extra for a “warranty”?

Because they’re selling the warranty as a product, not backing their work as a policy. Our guarantee isn’t an upsell. It’s a standard part of every job since 2004. The second visit is free because it shouldn’t have failed the first time.
