Most Boulder homes have never had their ducts professionally cleaned. At 5,430 feet, with wildfire smoke rolling in every summer and Chinook winds pushing plains dust through your vents year-round, your ductwork accumulates far more than the national average. We remove what has been building for years — completely, with before-and-after documentation, and no surprises on the bill.

Serving Boulder homeowners since 2014. We know Boulder's housing stock, its altitude challenges, and the air quality issues that come with living at 5,430 feet on the Front Range.

NADCA-aligned cleaning methods. Fully insured. We follow the ANSI/NADCA ACR standard — the industry benchmark for how ductwork is cleaned, by qualified technicians, with documented results on every job.

We are not a Denver company driving an hour to Boulder. We work in this city every day — Mapleton Hill, South Boulder, Gunbarrel, NoBo. We understand Boulder homes because we live here.
We are a locally operated air duct cleaning company in Boulder, CO. Not a franchise, not a national chain, not a Denver company that lists Boulder as a service area. Our team works in this city every day — cleaning ducts in homes from Mapleton Hill to Martin Acres, from Chautauqua to Gunbarrel (80309).
Boulder has specific indoor air quality challenges that national companies don’t understand: wildfire smoke that accumulates in ductwork from July through September, Chinook wind debris in external vent openings, semi-arid dust that never gets washed out by rain, and a housing stock where the median construction year is 1977. We built our service around those realities.
We follow practices aligned with the National Air Duct Cleaners Association (NADCA) — and before we start any job, we inspect and explain. After every job, we document. What we quote is what you pay. No bait-and-switch. No invented mold scares. No $49 coupons that become $600 invoices.

Using negative air pressure and HEPA-filtered equipment, we remove decades of dust, allergens, smoke residue, and debris. Typical job: 3–5 hours. Anyone done in under 90 minutes did not clean your ducts.

Beyond the ducts: air handler, evaporator coil, blower motor, and plenum cleaning. A fouled evaporator coil in Boulder’s semi-arid climate reduces system efficiency by 20–30%. We clean the full system — not just the registers you can see from the room.
We are not a franchise, not a national chain, not a Denver company that drives 35 miles and calls itself local. We work in Boulder every day — Mapleton Hill, South Boulder, NoBo, Gunbarrel, Chautauqua. We understand what older Boulder homes need, what wildfire smoke does to ductwork, and what altitude does to dryer vents. We quote flat-rate pricing before we start, document before and after, and never fabricate mold problems. If you do not need cleaning yet, we say so — and lose the job — rather than do unnecessary work.
A legitimate air duct cleaning in Boulder takes 3 to 5 hours. The equipment alone — a HEPA-filtered vacuum rated at 2,000+ CFM, rotary brush systems, containment units — costs tens of thousands of dollars to purchase and maintain properly. Here is what we do on every job:
We connect our HEPA-filtered vacuum to the main trunk line at the furnace, creating negative air pressure throughout the system. Everything we dislodge is pulled toward the vacuum into a sealed containment unit — nothing blows back into your living space. We then run a rotary brush through every supply and return line, working top to bottom. When we finish, we photograph the duct interior at multiple points so you see exactly what was in there and what clean looks like.
This is what the National Air Duct Cleaners Association (NADCA) recommends. It is what separates a real cleaning from the “blow-and-go” method that $49 operators use.
Real reviews from real homeowners across Boulder — Mapleton Hill, South Boulder, Gunbarrel, University Hill, NoBo. Same concerns you have right now. Same results they didn’t expect.
Real feedback, real results — every Boulder job focused on clean air, documented proof, and pricing that matches the invoice. Read our verified reviews on Google before you call.
Every job follows the same rigorous process — no shortcuts, no guessing. Before we start, you know exactly what we are doing and why. After we finish, you see documented proof.
We walk your entire system before touching a vent — every supply, every return, furnace cabinet, and main trunk line. We identify problem areas and tell you what we find. If your system does not need cleaning, we say so before any work starts.
We connect our HEPA-filtered vacuum to the main trunk line at the furnace. This creates negative air pressure throughout the entire duct system — every particle we dislodge gets pulled toward the vacuum into a sealed containment unit, not back into your home.
Working from the top floor down, we run a rotary brush through every supply and return line. The brush dislodges buildup from duct walls while the vacuum extracts it simultaneously. We clean the full run of every branch line — not just the registers you can see from the room.
Before-and-after photos of the duct interior at multiple representative points in your system. You see exactly what was in there and what clean looks like. We walk you through it before we leave. No guessing. No taking our word for it.
This is professional air duct cleaning Boulder homeowners can trust — NADCA-aligned methods, transparent pricing starting at $350 for most homes, and documented results every time.
Expect to pay $350–$750 for a typical Boulder single-family home. The range depends on square footage, number of vents, ductwork accessibility, and contamination level. A 1,200 sq ft condo with 8 vents costs less than a 2,800 sq ft two-story with 22 vents and original ductwork. That $49 coupon you see advertised is not real pricing — it is a bait-and-switch entry point. Real flat-rate pricing for Boulder homes starts at $350.
Every 2–3 years for most Boulder homes — shorter than the national NADCA recommendation of 3–5 years because Boulder's semi-arid climate, wildfire smoke season, and Chinook wind dust accelerate buildup. Homes with pets, allergy sufferers, children under 5, or recent wildfire smoke exposure should consider annual or biennial cleaning.
Yes. PM2.5 particles from wildfire smoke are small enough to pass through standard HVAC filters and deposit on interior duct walls. After the 2021 Marshall Fire that affected Louisville, Superior, and Boulder County broadly, the Colorado Department of Public Health and Environment specifically recommended HVAC duct cleaning for affected homes. After multiple smoke events, this residue continues releasing particles and odor every time the system runs.
3 to 5 hours for a typical Boulder home (1,500–2,500 sq ft, single HVAC system). Any company claiming to clean a full home system in 45 minutes is not performing a legitimate cleaning. The negative pressure setup, running a brush through every line, and post-cleaning documentation all take real time. If a technician is in and out in under 90 minutes, your ducts were not cleaned.
Extended drying time is the most common sign of a blocked dryer vent. At Boulder's elevation of 5,430 feet, air is thinner — dryers run longer cycles and produce more lint per load than at sea level. Combined with debris that Chinook winds drive into external vent openings, Boulder dryer vents block significantly faster than the national average. Annual dryer vent cleaning is strongly recommended for most Boulder homes as a fire safety measure, not just routine maintenance.
Ask four questions before booking: (1) What does a whole-home cleaning cost and what is included? (2) What type of vacuum — portable or truck-mounted, and what CFM rating? (3) Do you provide before-and-after photos of the duct interior? (4) What is your actual service address? Legitimate companies answer all four confidently. Companies quoting $49–$99, dodging equipment questions, or using Facebook posts as their storefront are worth avoiding. Verify through NADCA's member directory at nadca.com or the Colorado BBB before you call.
