Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
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.
Available Franchise Territories
Hollis Air Duct Cleaning is expanding, and we are doing it the slow way on purpose. No crowded maps, no overlapping vans, no two owners fighting over the same zip code. When you claim an open market, you get a protected territory that is yours to build. That means every dollar you spend on your name, your reputation, and your crew stays with you. First mover advantage in this trade is real. The first professional duct cleaning outfit in a market becomes the one homeowners call, the one property managers keep on file, and the one neighbors recommend by name. Right now, twelve major states have open territory. We would rather fill them with owners who work to The Garrison Standard than with anyone who just wants a logo.
Open Markets
These states have open territory available as of today. Each one has its own reasons for being a strong market for air duct cleaning, and a few stand out enough to mention here.
- Texas – Long cooling seasons mean HVAC systems run hard for months. Homes in Houston, Dallas, and San Antonio collect dust fast, and homeowners notice.
- Florida – Humidity keeps air handlers damp and duct interiors sticky. Mold concerns push duct cleaning from a maybe to a priority for a lot of Florida households.
- California – Wildfire smoke and urban smog settle inside ductwork. Homeowners in Sacramento, Riverside, and the Central Valley ask about indoor air quality more than almost anywhere else.
- Georgia – Metro Atlanta keeps adding subdivisions, and every new home has ductwork that will eventually need attention. The customer base grows on its own.
- North Carolina – The Triangle and Charlotte metros are full of families who stay put for decades. That means long-term relationships and repeat business, not one-and-done calls.
- Arizona – Dust is a fact of life in Phoenix and Tucson. Ducts fill with fine desert particulate, and homeowners know the difference a clean system makes.
- Tennessee – Nashville, Knoxville, and Chattanooga all have older housing stock with duct systems that have never been properly cleaned. The need is there and growing.
- Ohio – Seasonal swings put HVAC systems through a full cycle every year. Spring and fall are natural times for homeowners to call, which smooths out the calendar.
- Pennsylvania – Older homes, mature suburbs, and plenty of allergy season. Duct cleaning is a practical fix for people tired of dusting every week.
- Colorado – High desert air and forced-air heating in nearly every home means ducts accumulate a surprising amount of fine grit, even in newer builds.
- Washington – The Puget Sound corridor has dense suburbs and a lot of rainfall. Dampness plus ductwork makes cleaning a recurring need, not a luxury.
- Virginia – Northern Virginia and Richmond both have strong pockets of older homes and newer construction, which gives an owner two different customer bases from day one.
How Territories Work
A Hollis territory is a defined service area, written down and protected. We do not sell the same ground twice. When you claim a market, you get the exclusive right to operate under the Hollis name inside that boundary. No other Hollis owner can run jobs there, and no corporate van will ever roll through your streets. Your territory is your turf.
The Garrison Code applies to every territory the same way it applies everywhere else. Show up inside the window we gave. Put the price in writing before any work starts. Do the job by the book, the first time. Leave the site clean and squared away. Stand behind the work for a full year. That code is not a suggestion. It is the operating system, and it is what makes a Hollis van mean something to the homeowner who answers the door.
Territories are reserved on a first-come basis. When an owner signs and is approved, that market comes off the open list. We do not run countdowns and we do not pressure anyone into a decision in one phone call. But the reality is simple: when a market is claimed, it is claimed. If you are serious about a particular state or metro, the only way to know if it is still available is to call and ask. We will tell you straight what is open and what is gone.
