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 Denver Guarantee
We stand behind every duct run we clean in Denver with a written promise, not a handshake. Since 2013, we’ve served more than 52,000 homes, and every single job ended with two things: a written price agreed before we started, and a documented photo record showing what we found and what we left behind. Our 365-Day Done Right Promise means if the work isn’t right, we make it right - backed in writing on every job, not buried in fine print or subject to a manager’s mood. That’s Haven Standard Clause 1 (written upfront pricing) and Clause 5 (documented completion) in action, and it’s how we’ve operated since Tomas Reyes opened the first CleanRun truck.
What’s Covered
- Workmanship on every duct run, plenum, and register. We clean with negative-pressure extraction (a sealed vacuum system that pulls debris out without releasing it into your home), and we photograph the inside of every duct run before and after so you can verify the work yourself. If a register isn’t reseated properly or a duct run shows remaining debris within 365 days, we return and correct it at no charge.
- Parts handling during HVAC cleaning and duct repair. We use professional-grade equipment from Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman - brands you can look up independently - and we treat your system like we’d treat our own. If our crew damages a component during service, we repair or replace it. Haven Standard Clause 4: Equipment Integrity.
- Cleanup after the job. We lay protective covering before we open your system, and we leave your floors and surfaces as we found them. If we track debris or leave a mess, we’ll return to clean it or compensate you for professional cleaning.
- On-time arrival with named, verified technicians. Haven Standard Clause 3: Verified Crews. Your technician is background-checked, uniformed, and identified by name before arrival. If we miss our scheduled window without calling ahead, we discount your service. No exceptions.
- Honest pricing with zero bait-and-switch. The price we write before work starts is the price you pay. We don’t quote $89 to get in the door and then discover “extra vents” or “surprise contamination.” One flat price per system, agreed in writing, every time. If we find something genuinely unexpected - a collapsed duct in a Capitol Hill crawl space, a bird nest in a Cherry Hills Village exhaust run - we stop, show you the photo, and get your written approval before proceeding.
Our Satisfaction Promise

If you’re not satisfied with our work, you call us and we fix it. That’s the entire process. No escalation to a regional office, no “let us investigate and get back to you in 5-10 business days.” Tomas Reyes or his operations manager takes the call, reviews your photo record, and schedules the return visit.
Here’s how it works in practice. A homeowner in Stapleton called us last spring because a return duct in the basement still smelled musty after our initial cleaning. We pulled her photo record - 47 images from that job - and saw the debris build-up we’d cleared from the main trunk, but the flex duct to that specific return had a sag we hadn’t photographed from the right angle. We sent a crew back the next day, corrected the sag, re-cleaned the run, and added 12 new photos to her record. No charge. No argument. The 365-Day Done Right Promise isn’t a marketing line - it’s a printed document our technician signs and leaves with you, alongside your photo record and your written invoice.
We can offer this because we document everything. When a customer in Park Hill questioned whether we’d actually cleaned his entire system, we emailed his photo record within two minutes - 63 images, every duct run, timestamped, with before-and-after comparisons he could zoom into. The doubt disappeared. Documentation is our guarantee’s backbone.
Before
AfterLicensed & Insured Backing
A written promise is only as solid as the business behind it. CleanRun Air Duct Cleaning Denver is licensed and insured, with coverage that protects your property while we’re in your home and your system while we’re working on it. Our license number is published on this page, not hidden in a footer or available “upon request” - because Haven Standard Clause 2: Transparent Credentials means you verify before you invite us inside.
Insurance matters in this trade. We’re moving equipment through your home, accessing attic spaces in older Denver bungalows, and working around high-voltage HVAC components. If a technician accidentally damages a ceiling tile in a Wash Park vintage home or scratches a floorboard in a Congress Park remodel, our policy covers the repair. You don’t chase us, and you don’t file against your own homeowner’s policy.
Licensing matters too. Colorado requires specific credentials for HVAC and ductwork contractors, and we maintain ours without gaps. An unlicensed operator can disappear after a job goes wrong; our license is a public record you can check, tied to a business that’s served Denver since 2013 and completed over 52,000 jobs. Tomas Reyes has put his name on every guarantee document since day one.
The combination - licensed, insured, documented, and owner-attached - is what lets us promise the 365-Day Done Right Promise in writing and mean it. We’re not a van that showed up last month with a rented machine. We’re the crew that photographed the inside of your ducts, showed you the debris we removed, and left you proof you can reference a year from now if anything feels off.
How to Use Your Guarantee

If something isn’t right, call (720) 799-2292. A live person answers, 24 hours a day. Have your job number ready - it’s on your written invoice and your photo record cover sheet. We’ll pull your file, review the documentation, and schedule your return visit. Most corrections happen within 48 hours. For urgent issues - a register left loose, a cover panel not secured - we’ll often talk you through a temporary fix while the crew is en route.
Your guarantee doesn’t expire at 364 days because you forgot to call. If you discover an issue and your job date is within the 365-day window, we honor it. We’ve processed make-right visits in January for jobs done the previous February. The date on your written invoice controls, not our memory or your urgency.
What’s Not Covered (Because We’re Clear About Both Sides)
We don’t guarantee against new contamination. If you remodel your Highlands Ranch kitchen six months after we clean your ducts, construction dust will enter your system. That’s a new event, not a failure of our work. We don’t guarantee manufacturer equipment beyond what the maker warrants - if your Honeywell air cleaner fails, we facilitate the warranty claim but we don’t absorb the manufacturer’s obligation. And we don’t guarantee work we didn’t perform - if another company “cleaned” your ducts and you want us to fix their shortcuts, that’s a new service with its own written price and its own guarantee.
Free Second Opinion: Your Guarantee Before You Hire Us

Even before you’re our customer, we back our confidence in writing. Bring us any competitor’s written estimate for air duct cleaning in Denver, and we’ll put our own number next to it - line item by line item, in writing, no charge. You’ll see exactly what we include that they don’t: the photo record, the negative-pressure extraction, the background-checked crew identified by name before arrival. Haven Standard Clause 6: Informed Choice. No obligation to hire us, and no hard sell if our number is higher. Most homeowners who compare find our flat-system pricing eliminates the surprise add-ons that make “cheaper” quotes expensive by the final invoice.
Frequently Asked Questions
Yes. Your technician presents a printed guarantee document with your written price, signs it, and leaves it with you alongside your photo record and invoice. It’s not a website policy or a verbal assurance. If you didn’t receive it, call (720) 799-2292 and we’ll reissue it from your job file.
We keep every photo record indefinitely. Call us with your job number or address, and we’ll email your full set within minutes. A homeowner in Belcaro lost her physical folder during a move last year; we had her 71 images from 2019 in her inbox before we finished the phone call.
Yes. The 365-Day Done Right Promise applies to every service we perform: air duct cleaning, dryer vent cleaning, HVAC cleaning, duct repair and sealing, and air quality sanitizing. Each service has its own written scope and photo record, and each is covered.
Haven Standard Clause 3: Verified Crews requires us to identify your technician by name before arrival. You can also ask to see our crew verification binder, which we carry in every truck. It contains current background check documentation for every employee. We’ve shown it to skeptical homeowners in Hilltop and Cherry Creek; we expect the question and we’re prepared for it.
CleanRun has operated continuously since 2013, served over 52,000 homes, and maintains the insurance and licensing that lets us promise long-term backing. But we understand the concern. Your photo record, your written guarantee, and your invoice are your documentation - keep them. In the extremely unlikely event we couldn’t honor a claim, your documentation supports any legal recourse, and our insurance carrier remains obligated for covered incidents regardless of our business status.
Call (720) 799-2292 for any guarantee question, or to schedule service with a written price before work starts.
