Air Duct Cleaning in Fort Collins, CO

Your ductwork is the lungs of your house — every cubic foot of heated and cooled air passes through it. Over the years, ducts collect dust, construction debris, pet dander, and in our part of Colorado, fine ash from wildfire smoke season. Professional duct cleaning removes that buildup at the source, so your system bre

Technician vacuum-cleaning a home air vent

We clean ducts with truck-mounted source-removal equipment: powerful vacuum at the furnace pulling the whole system into negative pressure, while agitation tools dislodge debris from every run. It's the method the industry's own standards call for, and it's the only approach that actually cleans the full length of the ductwork.

When duct cleaning is worth it

We'll be straight with you: not every home needs it. Duct cleaning earns its keep in specific situations:

After construction or remodeling: drywall dust and sawdust settle deep in ducts and keep recirculating for years.
After wildfire smoke events: fine ash and soot coat duct interiors; cleaning removes what filters missed.
Visible dust blowing from registers: if you see puffs of dust when the system kicks on, the ducts are loaded.
Post-pest or post-tenant: rental turnovers and rodent activity leave debris no filter catches.
Never cleaned in 10+ years: especially in older Fort Collins homes with original ductwork. ASHRAE's equipment-life chart gives ductwork a 30-year median lifespan, so ducts installed in the 80s and 90s are living on borrowed time and usually carry decades of buildup.
Renovation of the HVAC system: new furnace or AC going onto old ducts? Clean the ducts so the new equipment starts clean.

If your ducts were cleaned three years ago and the house is tidy, we'll tell you to save your money. We'd rather have your trust than your duct-cleaning fee.

How source-removal cleaning works

System inspection. We check duct accessibility, note the layout, and look inside representative runs with a camera so you see the before condition.
Negative pressure setup. A high-powered vacuum connects at the air handler, pulling the entire duct system into negative pressure — everything dislodged gets sucked toward the vacuum, not blown into your rooms.
Agitation run by run. We work through each supply and return run with rotating brushes and compressed-air whips that scrub debris off the duct walls.
Register and grille cleaning. Every vent cover comes off, gets washed, and goes back on.
Furnace cabinet and blower area. We clean the accessible interior around the blower and coil — the dirtiest square feet in the system.
Final check. Camera back in to verify, system run to confirm airflow, and before/after photos for you.

The whole job typically takes 2–4 hours for an average home. You don't need to leave. It's loud near the vacuum, but there's no mess in the living space.

What duct cleaning doesn't do

Honesty matters here. Duct cleaning doesn't seal leaky ducts. According to ENERGY STAR, a typical duct system loses 20–30% of the air it moves, so if your ducts are bleeding heated and cooled air into the attic, you need duct repair, not cleaning. It doesn't fix mold growing from an ongoing moisture problem; that needs the moisture source addressed first. And it doesn't replace filtration — a good filter prevents the buildup from returning. We check for these issues during the inspection and tell you what you actually need.

Fort Collins duct realities

Our dust is relentless — high-desert soil, construction from the growth in Timnath and Severance, and agricultural dust from the plains all find their way into ductwork. Wildfire smoke season adds a layer of fine particulate that settles everywhere, including inside ducts. Older homes near Old Town and the university often have original ductwork with decades of accumulation and sometimes long-abandoned sections that still connect to the system. And swamp cooler homes converting to refrigerated air sometimes have ducts that were sized for evaporative cooling — worth evaluating while we're in there.

What affects the cost of duct cleaning

System size: number of supply and return runs (roughly, the number of vents).
Accessibility: ducts in an open basement clean faster than ones buried in a tight crawlspace.
Contamination level: heavy construction debris or pest cleanup takes longer than routine dust.
Add-ons: dryer vent cleaning pairs well with duct cleaning since we're already set up; ask about bundling.

We quote by the system after asking about your home's size and vent count — no bait-and-switch per-vent math on arrival. For reference, Angi's 2026 cost guide puts whole-house air duct cleaning at $250–$1,000 nationally (most homes pay $300–$700, averaging ~$475) — a market range, not our price.

Frequently Asked Questions

How often should air ducts be cleaned?

Every 3–5 years for most homes, more often if you have pets, allergies, or recent remodeling. After a wildfire smoke season that left ash everywhere, sooner. There's no benefit to annual duct cleaning — that's overselling.

Will duct cleaning help with allergies?

It removes the accumulated dust, dander, and debris reservoir inside the ducts, which helps — but ducts re-accumulate without good filtration. Pair cleaning with a quality filter (and consider air filtration) for lasting results.

How do I know if my ducts actually need cleaning?

Look for dust puffing from registers when the system starts, visible debris inside vent openings, musty odors when the system runs, or a recent remodel. We also run a camera through representative runs during the estimate so you can see the condition yourself.

Is duct cleaning messy? Will dust get all over my house?

No — that's the point of the negative-pressure method. The vacuum pulls everything toward itself; debris goes into our containment, not your rooms. We also seal each register as we work it. Your house stays clean.

Can you clean ducts in a crawlspace or attic?

Yes, as long as there's access. Tight crawlspaces and hot attics slow the job down, which we account for in the quote. If duct sections are physically unreachable, we tell you that upfront rather than charging for work we can't do.

Should I clean my ducts before or after getting a new furnace?

After the old equipment comes out and before the new one fires up — or coordinated with the installation. Clean ducts mean your new system starts life without inhaling a decade of the old system's dust.
