Our equipment & process

Professional Equipment. A More Thorough Approach to Duct Cleaning.

Not every duct cleaning involves the same equipment or scope of work. Our professional negative-air system and specialized cleaning tools let us address the accessible ductwork beyond the registers — the supply runs, returns, main trunks and plenums.

01 · Truck-mounted negative air

Powerful Suction. Professional Debris Removal.

Our truck-mounted negative-air system stays in the van. One large hose runs to your furnace, is sealed to the plenum, and pulls on the whole duct system while specialized tools loosen the buildup inside the runs.

Why it matters to you: the suction is on the entire system at once, so what comes loose in a trunk line has somewhere to go.

02 · Portable negative air

Professional Cleaning. Even in Challenging Spaces.

Not every furnace is an easy reach from the driveway. Our portable negative-air equipment gives us flexibility around difficult furnace locations and access conditions.

Why it matters to you: an awkward mechanical room or a long run from the street doesn’t turn into a reason to skip part of the system.

The Right Tools for the Ductwork You Can’t See.

Professional cleaning takes more than suction. We use specialized agitation tools to loosen accumulated debris along the duct runs — the branches and the larger passages that connect back to your HVAC system.

Why it matters to you: agitation without collection moves dust around; collection without agitation leaves it stuck to the duct wall. You need both.

Same Supply Line. Same Day.

Drag the handle. This run is well past the register, where a brush from the vent never reaches. Every customer gets this view of their own ductwork, before and after, as part of the job.

"Michael did our vents and discovered why a bedroom wasn't heating and cooling. The vent was plugged from the prior vent cleaner who ripped it up and created a clog! Michael is very professional and does a marvelous job, he even sanitized the vents and showed us on the camera it was sparkly clean!"

Debra B. · Google review, Sep 2026
★★★★★

"I highly recommend this company. They came out to clean my vents, but weren't able to due to there being too much air loss from leaks. Michael explained the process and the problem very thoroughly. He could have fudged things and told me they were 'clean,' but he didn't. 5-Stars for an honest company with great values."

A Whole-System Cleaning. Not a Quick Pass Through the Vents.

Every air duct cleaning is the same job, in the same order, in every city we serve. This is what $0.35 per square foot covers — the work itself, not a list of upgrades.

  • Every accessible supply and return — all of the runs, not just what you can reach from the register
  • Main trunk lines and both plenums — opened, cleaned by hand, photographed
  • Light furnace and coil cleaning — done last, so clean air is not pushed through a dirty coil
  • Camera running the whole job — before, during and after, inside your own ducts
  • Truck-mounted negative air — rated at 14,000+ CFM, pulling on the whole system while every run is agitated
  • Floor runners and corner guards — your home protected from the first step in
  • Your own photo report — in your app the same day, no download, no password
  • 3-month workmanship warranty — on every completed job
  • No hook-up, trip or travel charge — in any city we serve

No surprise charges and no pressure to add services. Optional dryer vent and bathroom exhaust cleaning are priced in your quote and only added if you choose them — never a second price once the truck is in your driveway.

A thorough cleaning should not be something you have to buy again next year. How long a system stays clean depends on filtration, pets, remodeling and how the house is used, so we do not put you on an automatic schedule. We clean the accessible system completely, document it in your app, and if we camera your ducts and they do not need it yet, we tell you.

Treasure Valley air quality

What Treasure Valley Air Leaves Behind in Your Ducts.

Wildfire smoke in summer. The country’s worst pollen city in 2026. Winter inversions that hold smoke over the valley floor. Your HVAC return pulls that air back through the house every day, and what the filter doesn’t catch can settle inside your ductwork.

Approximate seasons in the Treasure Valley. They shift year to year.
Summer smoke

Wildfire smoke

In July 2024, smoke from Oregon and California fires pushed Boise-area air to “very unhealthy” on July 23, the highest July reading since federal AirNow data began in 2000, the Idaho Statesman reported. In July 2026, Idaho DEQ issued an air quality advisory for Ada, Canyon, Gem, Payette and Washington counties as Oregon and Washington smoke pushed the valley into the red. The EPA notes fine smoke particles get indoors through doors, windows, small gaps and fresh-air intakes.

March through October

Pollen

Boise ranked #1 in the nation in the 2026 Allergy Capitals report from the Asthma and Allergy Foundation of America, up from 95th the year before. Tree pollen peaked earlier, grass pollen lasted longer, and weed pollen peaked higher. Boise Valley Asthma and Allergy Clinic tracks pollen from early March through Halloween: pine and cottonwood first, grass into summer, then weeds and sage in the fall.

Winter

Inversions & wood smoke

The Treasure Valley is known for winter inversions, when cold, stagnant air holds pollution close to the ground. Idaho DEQ has pointed to more people burning woodstoves as the weather turns. During air quality alerts, outdoor burning is restricted in Ada County and in Canyon County cities. Those are the same weeks your furnace runs the most.

Year-round

Dust, dander & dust mites

Everyday household dust, pet dander and dust mites are some of the most common indoor allergy and asthma triggers, according to the EPA. The American Lung Association says up to 85% of people with asthma are allergic to dust mites. Return grilles pull this dust back toward the furnace with every cycle.

How it builds up inside your duct system

  1. Pulled in at the returns.Return grilles draw room air back to the furnace, carrying whatever is in it. The National Air Duct Cleaners Association notes that smoke and soot most often enter a duct system through the return side.
  2. Only partly filtered.For wildfire smoke, the EPA recommends a filter rated MERV 13 or higher, if your system can handle one. Lower-rated filters let more fine particles through.
  3. Settles in returns and trunk lines.Over the years, dust and debris collect on duct surfaces. The EPA lists ducts “clogged with excessive amounts of dust and debris” as a reason to consider cleaning.

Who notices it most

CPAP users

A CPAP machine pulls bedroom air through a small filter all night. The Sleep Foundation advises replacing CPAP filters more often in a dusty or smoky home, or with pets or a wood-burning fireplace. During smoke season, check yours often and follow your equipment maker’s schedule.

Allergy sufferers

Pollen, pet dander and dust mites are common allergy triggers, and the EPA notes allergic reactions build with repeated exposure. With Boise ranked the toughest U.S. city for pollen allergies in 2026, what collects indoors adds to what people already face outside.

Asthma, COPD & other respiratory conditions

The CDC says wildfire smoke can cause coughing, wheezing and asthma attacks, and that people with asthma, COPD or heart disease, children and pregnant people face higher risk. The EPA lists dust mites, pet dander and mold as asthma triggers.

What duct cleaning can and can’t do

We’ll be straight with you. The EPA says duct cleaning has never been shown to prevent health problems, and that much of the dust in ducts sticks to duct surfaces. It does recommend considering cleaning when ducts are clogged with excessive dust and debris, have visible mold, or have rodents or insects. That’s exactly what our free camera inspection shows you before you decide. If someone in your home has breathing symptoms, talk with your doctor first.

Smoke-season checklist

  • Use a MERV 13 or higher furnace filter if your system can handle it.
  • During smoky days, set the thermostat fan to “On” instead of “Auto.”
  • Check furnace filters often and change them when they’re dirty or smell of smoke.
  • Run a portable HEPA air cleaner in the bedroom.
  • Check your CPAP filter more often than usual.

Dirty Ducts Boise was built by Michael Lossing one job at a time, across 4,700+ Treasure Valley homes. The way we clean a system was worked out in those homes, and it does not change based on who is on the truck.

It started with dryer vents on the side and a Nextdoor neighbor who said she’d be the first duct job if Michael bought the equipment. Every tool in the fleet since has been paid for by the people who hire us — no investors, no franchise.

Air Duct Cleaning Questions, Straight Answers

No. The whole system is under negative pressure from the truck for the entire job, so what comes loose goes to the truck, not into the room. We run floor runners and corner guards from the door to the furnace, and we show you the camera footage before we leave.

No. $0.35 per square foot of living space, $399 minimum, told to you before we book. Each additional furnace is $249 and you hear that up front as well. There is no hook-up fee, no trip charge and no “we found mold” upgrade. Optional dryer vent and bathroom exhaust cleaning are priced right on the estimator and only added if you choose them.

The inside of your main trunk lines and the runs behind the registers, before, during and after the cleaning, plus anything we find on the way: a crushed flex run, a disconnected duct, construction debris that has been there since the house was built. It goes into your own app page the same day.

Floor runners and corner guards go down first. Registers are removed and reinstalled, not pried. The dryer, if we clean the vent, is pulled, cleaned behind, reconnected and checked. Every completed job carries a 3-month workmanship warranty.

$0.35 per square foot of living space for the complete accessible system, with a $399 minimum. A 1,500 sq ft home is $525; a 2,000 sq ft home is $700. That covers every accessible supply and return run, the main trunks, the plenums, light furnace and coil cleaning, and before-and-after photos. Each additional furnace is $249. Optional dryer vent and bathroom exhaust cleaning are priced on the site and only added if you choose them. You know the exact number before we book.

A typical Whole Home Air Reset™ takes 2 to 4 hours, depending on the size of your home and the complexity of the duct system. Two-furnace homes take longer. You do not need to leave.

It depends on the condition of the system, not the calendar. Many homes go several years between cleanings; pets, a remodel, weak filtration or a bad wildfire-smoke summer shorten that. A thorough cleaning should not be something you have to buy again next year, and if we camera your system and it does not need it yet, we will tell you. How often ducts really need cleaning →

Yes. Bundled with a duct cleaning, a dryer vent cleaning is $49 — roof or side exit — and we replace the dryer-to-wall connection free if it needs it. On its own, a dryer vent cleaning is $119 for a side-wall exit or $149 through the roof; repeat customers pay $96.
