Contact CleanRun Air Duct Cleaning Littleton - Free Air Duct Cleaning Estimate in Littleton
Call us at (720) 315-7291 for a free estimate on air duct cleaning in Littleton. When you reach our team, you’ll speak with a live coordinator who’ll connect you with our local crew. No hard sell, no pressure to book on the spot. We’ll ask about your home, explain what the visit covers, and if you like, schedule a free assessment. We’re answering calls around the clock.
What Happens When You Call
Step 1: We answer and listen. Our live coordinator picks up, day or night. You’ll describe your home, your concerns, and what prompted the call. Maybe it’s dust settling faster than it used to, or a musty smell when the furnace kicks on. We take notes so the technician who arrives already knows your situation.
Step 2: We schedule your free assessment. We find a window that works for you. You’ll get a real appointment with a named technician, plus a text when they’re on the way. That’s Clause 2 of the Haven Standard: arrive on schedule, with notice.
Step 3: You receive a written estimate. Our technician inspects your system with a camera, shows you what they found, and delivers a flat price per system in writing. One price, one scope, no per-vent add-ons. This is Clause 1: have it in writing before anyone starts.
Step 4: We complete the work and document it. If you approve the estimate, we clean every run, photograph before and after, and leave you with the evidence. Clause 4 of the Haven Standard: evidence on every job.
Why Littleton Homeowners Call Us First

- We’re local to Littleton. Our team lives and works in the same metro area, so we understand the specific challenges of Colorado’s dry climate and high-altitude heating cycles. We know what the dust load looks like after a windy March in the foothills.
- Every pro is properly credentialed. Every technician working under our name is required to hold the license and insurance Colorado requires. We carry general liability and workers’ compensation coverage. License numbers are provided on request.
- Our pricing is flat and fixed. One price per HVAC system, agreed in writing before work begins. No per-vent surcharges, no “while we’re in here” upsells. Clause 5 of the Haven Standard: no surprises.
- We guarantee the workmanship. If you’re not satisfied with the cleaning, we’ll return and make it right. Our guarantee is printed on every estimate, not buried in fine print.

Frequently Asked Questions - Booking & Estimates

Yes. The in-home assessment and written estimate cost nothing, and you’re under no obligation to book. We believe you should see the inside of your ducts and know the exact price before deciding. Call (720) 315-7291 to schedule yours.
We typically schedule assessments within a few days of your call. Exact timing depends on current demand and your availability. Our coordinator will offer real windows, not vague promises. Call (720) 315-7291 and we’ll find a time that works.
No. Our flat price per system applies regardless of when we perform the work. We don’t penalize homeowners for scheduling around their jobs and kids. The estimate you approve is the invoice you pay.
Know the approximate age of your home, the last time your ducts were cleaned (if ever), and any specific concerns like dust, odors, or allergy symptoms. If you’ve had recent remodeling, mention that too. The more we know upfront, the better we can prepare.
We accept all major credit cards, debit cards, checks, and cash. Payment is due upon completion, after you’ve reviewed the before-and-after photos and signed off on the work. No deposits required for standard residential jobs.
