A Hundred Years Of Boise Houses, And What Each One Hides In The Ducts
Boise grew in rings: the original town along the river and up into the North End, the Bench after the war, West and Southeast Boise through the 80s and 90s, and Harris Ranch and the foothills since. Each ring has its own ductwork, and each one has a different problem inside.
The Original Boise Home (1890–1945)
What we find: Basement furnaces converted from gravity to forced air, with large rigid trunks and long runs to the upstairs bedrooms. Decades of dust, coal-era soot from the original furnace, and joints that have shifted through three or four furnace replacements.
What we do about it: Camera inspection first, every time. Intact galvanized trunk is the easiest duct we clean — smooth and rigid, nothing to hold dust. A bad joint or a disconnected run gets shown to you on camera before we touch it, so there are no surprises in the basement and none on the bill.
The Bench & Post-War Ranch (1946–1979)
What we find: Single-story ranches with floor registers and a furnace in the garage or a closet. Sixty to seventy years of dust, pet hair and everything that fell through the floor registers, in a system that has never once been opened.
What we do about it: We seal every register and pull the whole system from the truck under negative air, then open the trunk and both plenums and clean the coil. These are the jobs where the before-and-after video makes people say "that was in my house?"
The Two-Story & The New Build (1980–today)
What we find: Flex-duct runs through the attic to the upstairs bedrooms, two-furnace systems in the larger homes, and in anything built since 2010, construction debris sealed in before move-in and circulated ever since.
What we do about it: We start at the main trunk where the heavy material is, agitate every branch — the attic runs especially — back to the truck, then the plenums and the coil. Two furnaces means two complete cleanings, both filmed, both quoted up front.
Four Things The Boise Valley Does To Your Ductwork
Boise sits in a bowl between the foothills and the Owyhees, and the bowl has a particular set of air problems. All of them settle inside the duct system.
- Winter inversionsWhen cold air gets trapped under a warm layer, the valley's particulate has nowhere to go — and it happens in exactly the weeks the furnace runs the most. The return side of the system pulls it in and the trunk lines hold it until spring.
- Wildfire smokeLate-summer smoke from Idaho, Oregon and California parks over Boise for days at a time most years. Smoke particulate is fine enough to pass a standard filter and coat the inside of the ductwork and the coil.
- Foothills dust and cottonwoodNorth-side and East End homes get dry foothills dust on every breeze. Every home near the river or the Greenbelt gets June cottonwood fluff in the returns. Both end up in the trunk.
- Old houses and old furnacesBoise has more pre-war housing than any city in the state. Gravity-furnace conversions, coal-era soot, and ductwork that has outlived four furnaces hold more than anything built since.
Boise Neighborhoods We Work In Every Week
ZIP codes 83702 through 83716. From the foothills to the Boise-Meridian line and from Harris Ranch to the airport, our trucks are somewhere in Boise every working day. Here is what we typically find, neighborhood by neighborhood.
North End & Hyde Park1890–1940
Bungalows, four-squares and Victorians with basement furnaces and rigid metal trunks. Gravity-to-forced-air conversions and shifted joints are common. Camera first, always.
East End & Warm Springs1900–1950
Larger original homes along Warm Springs Avenue and up toward the foothills. Bigger systems, sometimes two furnaces, and the same century-old ductwork as the North End.
The Bench1945–1975
Vista, Morris Hill, the Depot Bench. Post-war ranches with floor registers and garage furnaces — sixty years of dust in a system nobody has opened. Our most dramatic before-and-afters.
West Boise & Collister1965–1995
Ranches and split-levels off State Street, Ustick, Cole and Fairview. First-generation flex duct in the attic, and a lot of pets.
Southeast Boise & Columbia Village1985–2010
Two-story family homes off Federal Way, Parkcenter and Amity. Long attic flex runs to the upstairs bedrooms and a lot of homes hitting their first cleaning at 20 to 30 years old.
Harris Ranch, Barber Valley & The Foothills2000–today
The newest and largest homes in the city. Two-furnace systems, attic units, and builder debris still in the ducts of anything built in the last ten years.
Boise State, the Depot Bench, Northwest Boise, Southwest Boise, the airport corridor — wherever you are in the city, we have already been on your street. Not sure? Call (986) 386-4495.

Not Every Duct Cleaning Quote Includes the Same Work.
Before hiring any company, ask whether the quoted price includes supply ducts, return ducts, main trunk lines, plenums, and a final inspection. Two quotes can look similar while covering very different amounts of work. At Dirty Ducts Boise, we clearly explain what’s included before your appointment and provide documentation of the completed cleaning. Here is how a limited cleaning usually differs from a whole-system cleaning:
- A low "whole house special" price usually covers the first two or three feet inside each register — the part you can see with a flashlight. Ask whether the basement trunks, the attic runs and the plenums are opened.
- Ask whether the price can change once the crew is inside, and whether a second furnace is priced before the appointment. On a two-furnace foothills home that is the difference between the quote and the invoice.
- Ask whether the furnace coil is included and whether you will see the inside of the system on camera. The main trunk lines hold most of the debris, and a brush through the register never reaches them.
- We quote one number by square footage before we arrive, tell you up front if a second furnace is $249, pull 14,000+ CFM on the whole system from the truck, open the trunks and plenums, clean the coil last, and show you the before-and-after on camera. The number does not change in your driveway.
What "Whole System" Means When We Say It
Nothing below is an add-on. This is the job, on every house in the city.

The Five Steps We Do In Every Boise Home
Same order, every house, whether it is a 1910 bungalow on 13th Street or a 2024 build in Harris Ranch.
Inspect on camera
We run a camera into the trunk lines and the returns before touching anything. On an older Boise home this is where we check the gravity-conversion trunks and the joints, so you see what you actually have.
Protect the house
Floors around the furnace and down the hall are covered, registers are pulled and set aside, and the truck is staged in the driveway or the alley — whichever gets the hose closest to the furnace.
Clean from the truck
The truck-mounted vacuum pulls 14,000+ CFM of negative air on the whole system. Every supply and return branch is agitated back toward the trunk, then the trunks, both plenums and the coil are opened and cleaned. Two furnaces means we do it twice.
Verify on camera
A second camera pass through the same lines, side by side with the first. The video is yours if you want it.

Things Boise Homeowners Ask Before They Book
$0.35 per square foot of living space for the complete accessible system, with a $399 minimum. A 1,800 sq ft Bench ranch is $630; a 2,600 sq ft Southeast Boise two-story is $910. That covers every accessible supply and return line, the main trunks, both plenums, the furnace coil and a camera inspection before and after. If the house has a second furnace — common in the foothills and in larger East End and Harris Ranch homes — that second system is $249, and we tell you before we book.
Almost always, and it usually cleans better than a new house, because old rigid metal duct is smooth. Most North End and East End homes had a gravity furnace in the basement that was converted to forced air decades ago, so there are big trunks down there. We camera the whole system first; if we find a disconnected joint or a section too deteriorated to clean, we show you on screen before we do anything else.
Floor registers and a furnace in the garage or a hall closet, and sixty or seventy years of dust, pet hair and whatever went down the registers — in a system that has never been opened. Bench ranches are some of the most satisfying jobs we do, because the before-and-after is dramatic and the rigid duct cleans out completely.
Each furnace runs its own trunk, plenums and coil, so each system is its own cleaning. The first is priced by square footage and the second is $249. That is on the quote before we book, not something discovered in your mechanical room.
This is the most common surprise in Boise. New construction seals drywall dust, sawdust, insulation and packaging inside the ductwork before anyone moves in, and then the furnace circulates it for years. A first cleaning on a five-year-old house regularly fills the collection bag, and the hot-dust smell from the furnace goes away with it.
A single-system home is most of a morning or afternoon. A two-furnace foothills home is a half day and sometimes a little more. You do not need to leave, and you do not need to move furniture — we handle the registers and cover the floors around the furnace.
Yes, and in a Boise house with the laundry upstairs or a roof exit, you should. With a duct cleaning the dryer vent is $49, roof or side, and we replace the dryer-to-wall connection free if it needs it. On its own, a new-customer dryer vent cleaning is $119 for a side-wall exit or $149 through the roof — details on our Boise dryer vent page.
