365-Day Done Right Promise - if it's not done right, we make it right

What Our Promise Actually Means

If the work we did in your home isn’t right, you call us, and we come back and fix it – no charge, no argument, no paperwork maze to run first. That’s the whole thing. Every job Hollis Air Duct Cleaning completes is covered in writing for a full year under the 365-Day Done Right Promise, which is the same guarantee stamped on every Garrison Partners job across 22 states. You don’t need to prove anything beyond the fact that the work isn’t holding up. We issued the guarantee, and we honor it. The price you were given before we started is still the number on the invoice when we leave. Nothing added at the door, nothing negotiated afterward. One written price, one year of coverage, one crew that knows how to stand behind its work.

Why We Answer Fast, Everywhere

A one-truck shop can’t pick up the phone at midnight on a Saturday. We can, because Garrison Partners built Hollis around local crews that are already in your region – not dispatched from a central hub three states over. When you call (361) 326-5060, a real person answers. Not a recording, not a callback queue. A person who can confirm your appointment within one business hour of that call and schedule most visits within two business days.

That speed is a function of how we’re structured. Twenty-two states, independently owned locations, stocked vehicles, and technicians who work in the same zip codes week after week. They know local systems, local equipment brands, and local conditions. A national brand with local roots isn’t a marketing line here – it’s the reason the window we quote you is a window we can actually keep.

How We Make It Right

You Tell Us

Call (361) 326-5060 and let us know what’s wrong. That’s the whole first step. You don’t file a form, you don’t wait for a case number, and you don’t track down the technician yourself. Tell the person who answers what isn’t right, and we take it from there.

We Come Back Out

We schedule a return visit – no fee attached, no new estimate to review. The 365-Day Done Right Promise covers this visit the same way it covered the first one. A background-checked, uniformed technician shows up inside the window we gave you, because that’s part of The Garrison Standard too.

We Fix It

The technician looks at the work, identifies what failed, and corrects it using the same professional-grade equipment used on the original job – Rotobrush rotary brush systems, Nikro negative-air machines, filtration products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman where applicable. The fix is done by the book, not patched over.

You Sign Off

We don’t consider the job closed until you do. Before the technician leaves, you walk through the result and confirm it’s right. If it isn’t, we stay in the conversation until it is. Your sign-off matters – it’s how the Garrison Standard closes every job, the first time and any time after.

What Stands Behind the Promise

Promises are only as solid as the people and systems behind them. Here’s what’s actually backing this one.

Every technician Hollis sends to your home is background-checked and shows up in uniform. You know who is walking through your door before they arrive. That’s a requirement under The Garrison Standard, not an option individual locations get to skip.

The written price you receive before any work starts is the price you pay. No hourly rates, no subscriptions, nothing to join or sign up for. Every job is priced job-by-job off a free written estimate, confirmed before a single tool comes off the truck.

The equipment on those trucks isn’t consumer-grade. Rotobrush rotary brush systems agitate debris from duct walls the way commercial crews handle it. Nikro negative-air machines pull that debris out under controlled negative pressure so it doesn’t redistribute through the house. Filtration products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman round out what’s available on the job. These are the same tools professional facilities crews use, and our technicians explain what each one does in plain terms before they start.

And behind all of it: Garrison Partners, the family company that has operated to the same standard since 2004. Each Hollis location is independently owned, but every one of them agreed to work under The Garrison Code – show up inside the window, price in writing, do it by the book, leave the site clean, stand behind the work for a full year. The family stands behind the brand, and the brand stands behind the crew that shows up at your door.

Ask Us to Prove It

The best version of this promise isn’t something you read – it’s a technician who showed up on time, handed you a written price, did the work correctly, and left your home clean. Call (361) 326-5060 and we’ll get started. You can also book online. The full terms of the 365-Day Done Right Promise are on our terms page – read them before you call if you’d like.
