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.
The CleanRun Air Duct Cleaning Littleton Guarantee
We stand behind every air duct cleaning job in Littleton with a written guarantee, not a handshake. Since 2013, we’ve served more than 52,000 homes, and every single one received a written price before work started and a documented photo record when our crew left. That hasn’t changed. Our 365-Day Done Right Promise means if the work isn’t right, we make it right - backed in writing on every job, not just stated in marketing copy. No manager approval needed, no runaround. Tomas Reyes, Owner, put this in place from day one because a guarantee that requires permission isn’t a guarantee at all.
What’s Covered
- Workmanship on every duct run. We guarantee the cleaning itself - the negative-pressure extraction (suction that pulls debris out of the system) we perform on each duct run, the register (vent cover) removal and cleaning, and the plenum (the main distribution box connecting your HVAC unit to the ductwork) access and service. If a run was missed or not fully cleaned, we return and complete it at no charge.
- Parts handling during service. If we remove a register, access panel, or plenum cover during cleaning and it doesn’t go back exactly as found, we replace or repair it. Ductwork in Littleton homes, especially older builds in Kipling Hills and the historic downtown district, can have brittle fittings. We photograph condition before we touch anything, and we stand behind how we leave it.
- Cleanup after the job. Our crews use drop cloths, corner guards, and shoe covers. If we track debris, leave dust, or fail to protect your floors and walls during service, we’ll pay for professional cleaning. The photo record we deliver includes shots of your space before we start and after we finish.
- On-time arrival with named technicians. Haven Standard Clause 3: Verified Crews means you get the technician’s name before arrival, and that technician arrives in a marked CleanRun vehicle, in uniform, background-checked. If we fail to communicate who is coming or they don’t match the description, the service call is free.
- Honest pricing with no surprises. Haven Standard Clause 1 requires a written price before any work starts - always, on every job, before a single panel comes off. If we quote $340 for a full system cleaning and find something unexpected that changes scope, we stop, explain, and get your written approval before continuing. The price you agree to is the price you pay.
Our Satisfaction Promise

If you’re not satisfied with your air duct cleaning in Littleton, you call us. That’s it. No forms, no escalation to a regional office, no “let us look into it.” Tomas Reyes personally reviews every satisfaction concern that comes in, and our crew returns to make it right. The 365-Day Done Right Promise gives you a full year - because problems from duct cleaning don’t always show up the same afternoon. Maybe it’s a register that doesn’t sit flush after reinstallation, or a noise from the plenum area that wasn’t there before, or you simply don’t see the difference you expected when you check the photo record we delivered. Whatever it is, we come back. We’ve honored this on jobs in Columbine Valley where a homeowner questioned whether a specific duct run had been cleaned (the photo record showed it had, but we cleaned it again anyway), and in Ken Caryl where a family noticed dust settling unusually fast after service (we found a filter installation issue from a prior HVAC contractor and fixed it). The promise is real because it’s written, because Tomas Reyes puts his name on it, and because we’ve had twelve years to prove we mean it.
Before
AfterLicensed & Insured Backing
Every guarantee needs something behind it. For CleanRun Air Duct Cleaning Littleton, that’s state licensing and full insurance coverage. We’re licensed to perform HVAC cleaning and duct repair work in Colorado, and we carry general liability and workers’ compensation policies that protect your property and our crew while we’re in your home. This matters in Littleton specifically because many duct cleaning operations are unlicensed - they own a Rotobrush machine and a van, but no regulatory oversight, no bonding, no recourse if they damage your system or a worker gets injured on your property. Our license number is published on this page, not buried in a footer where you’ll never find it. Our insurance certificates are available on request. The H.A.V.E.N. Standard requires this transparency because a guarantee from an unlicensed, uninsured operator is just words. Ours is backed by documentation you can verify independently.
How to Use Your Guarantee

You don’t need your original paperwork. Every CleanRun customer receives a job record with the written scope, the written price, the before-and-after photo record of every duct run, and the 365-Day Done Right Promise in writing. If you have a concern, call (720) 315-7291. A live person answers, 24 hours a day. Describe what you’re seeing or experiencing. We’ll pull your job record, review the photo documentation, and schedule a return visit if needed. Most concerns resolve in one trip. If we’ve made a genuine error, we fix it and we apologize. No charge, no argument, no expiration within the 365-day window.
Free Second Opinion: The Guarantee Before the Guarantee
Not a customer yet? Our guarantee starts with honest information. Bring us any competitor’s written estimate for air duct cleaning in Littleton, and we’ll put our own number next to it - free, in writing, no obligation. We’ve done this for homeowners in Highlands Ranch who were quoted $89 “whole house” specials that would have ballooned to $800 on arrival, and for families in Centennial comparing sanitizing add-ons they didn’t need. The Haven Standard Clause 1 price guarantee applies even before you choose us. You’ll know exactly what we charge, what it covers, and what you’ll receive before any work starts.
Equipment & Workmanship Standards

Our guarantee is only as good as the tools and people behind it. CleanRun crews use Rotobrush and Nikro rotary brush systems for agitation and debris removal, Abatement Technologies negative-pressure extractors for containment, and Honeywell, Aprilaire, and Guardsman air quality products where sanitizing or filtration upgrades are appropriate. These are trade-recognized brands you can look up independently - not proprietary “secret formula” equipment with unverifiable claims. Our technicians train on manufacturer specifications and operate under the full H.A.V.E.N. Standard, which includes background checks, uniform identification, and named-technician communication before every arrival. The equipment roster and crew standards are part of what we guarantee: if we show up with unmarked tools or an unidentifiable technician, the service call is free under Haven Standard Clause 3.
What We Don’t Guarantee (And Why)
We don’t promise to solve medical conditions or guarantee specific air quality meter readings after cleaning. Duct cleaning removes built-up debris from your HVAC system - dust, pet dander, construction residue, the debris build-up we regularly find at the first elbow in older Littleton homes near the South Platte River floodplain where humidity variation is real. It doesn’t cure asthma, eliminate all allergens, or replace medical treatment. We don’t guarantee your energy bills will drop by a specific percentage; system efficiency depends on insulation, windows, thermostat habits, and equipment age beyond what duct cleaning addresses. What we do guarantee is the work itself: every duct run cleaned, every register handled properly, every photo delivered, every price locked in writing before we start. That’s concrete. That’s enforceable. That’s the CleanRun difference.
