Denver air duct cleaning prices: a 2026 comparison
Price research checked September 29, 2026. Local advertised packages reviewed for this guide start at $249–$395, depending on the provider and included work. Those starting prices are not a citywide average or a ceiling. More vents, multiple systems, difficult access, and separate equipment services can change the total.

Published Denver-area prices and what they cover
| Service and source | Listed amount | Scope to check |
|---|---|---|
| Denver Kwik Dry: duct cleaning | From $249 for up to 10 vents; $35 per extra vent | The provider describes register cleaning and brushing/vacuuming. Confirm the system count and access requirements. |
| The Duct Guys: house-size packages | From $295 up to 2,500 sq. ft.; from $395 for 2,500–5,000 sq. ft. | Single accessible furnace, supply and return vents, up to three main lines, and qualifying side-wall dryer vent service. Access panels and difficult equipment locations can add charges. |
| Lowe’s Air Duct Cleaning: Denver promotion | $299 ducts; $399 ducts plus dryer vent; $499 ducts plus blower and coil wash | One system. The displayed offer expires September 30, 2026; check the provider for any replacement offer after that date. |
| Mile High Ducts: dryer vent service | $250 wall outlet; $500 roof outlet | Separate dryer exhaust service. The company identifies roof access as more challenging. |
These listings describe different scopes. A package with a vent limit should not be compared directly with one covering an entire system unless the included components and exclusions match. They are reference points, not Coolerado offers.
How the price changes as the job grows
These examples use the published unit rates above and below. They show the arithmetic, not a prediction of your invoice. They do not add unlisted taxes, access charges, repairs, or optional work.
| Example | Calculation | Subtotal |
|---|---|---|
| 15 vents using Kwik Dry’s listed rate | $249 + (5 × $35) | $424 |
| 20 vents using that same rate | $249 + (10 × $35) | $599 |
| 12 supply vents, two returns, one main line using The Duct Guys’ itemized rates | (12 × $20) + (2 × $30–$35) + $100–$150 | $400–$460 |
| 20 supply vents, four returns, two main lines using those itemized rates | (20 × $20) + (4 × $30–$35) + (2 × $100–$150) | $720–$840 |
Package and itemized methods are alternatives; do not add every itemized charge to a package that already includes the work. Ask which method applies. Square footage alone cannot tell you the number of returns, main lines, or independent systems.
Extra vents, access, and dryer vent costs
- Itemized duct components: The Duct Guys lists $20 per supply vent, $30–$35 per return, $100–$150 per main line, and $25 per access panel. View the rate listing.
- Dryer vent only: Kwik Dry lists $99 for a side-wall outlet and $149 for a roof outlet; its duct-cleaning add-on prices are $50 and $99 respectively. View the dryer vent prices.
- Multiple systems or commercial work: Request a property-specific estimate. A residential package for one furnace is not a price for an entire commercial building.
- Repairs and equipment cleaning: Ask for separate line items. Duct cleaning does not automatically include duct replacement, blower service, coil work, or chimney services.
When comparing a new estimate with an older quote, check the included work, system count, and date. Coolerado will confirm a current total for the proposed work.

Details that shape the estimate
| Detail | Why it belongs in the discussion | Question to ask |
|---|---|---|
| Number of systems | The proposal needs to identify which equipment and connected ducts it covers. | Does the total cover every system I asked about? |
| Supply and return ducts | A count of room openings alone does not explain the full scope. | Which supply branches and returns are included? |
| Condition | The recommended cleaning level should relate to the findings. | What supports this recommendation? |
| Access | Enclosed sections, equipment locations, and occupied areas need to be discussed. | What can be reached, and what is excluded? |
| Additional services | Dryer vent work, repairs, and equipment services may have separate scopes. | Are these included or priced separately? |
| Preparation and cleanup | The estimate should explain responsibilities around the work. | What do I need to prepare, and what cleanup is included? |
Share what you know without guessing. If you are unsure how many systems serve the property or where the ducts run, say so. The team can discuss which details need to be checked before the scope is settled.
Read the included work before the total
A quote for one system and a quote for two systems are not directly comparable. The same applies when one proposal includes return ducts or separate dryer vent work and another does not. Ask each provider to identify the included areas and tasks so you can compare the actual work.
Keep a copy of the estimate and any agreed changes. If a description is unclear, ask for it to be explained before accepting. A short list of specific tasks is more useful than a package name that leaves you guessing about coverage.
Fair pricing starts with a clear scope. You should know what is included and what the job will cost before you agree to the work.
A checklist for comparing proposals
- The property and systems covered by the estimate.
- The included supply ducts, returns, registers, and other components.
- The recommended cleaning level and the reason for it.
- Known access limits and any excluded sections.
- Separate charges for parts, repairs, or additional services, if proposed.
- Preparation, cleanup, and responsibility for moving items.
- The total proposed price and any conditions attached to the estimate.
Ask how a change in scope would be handled. If the visit identifies an issue beyond the original request, have the added work and price explained before deciding. Do not assume a cleaning quote includes repairing damaged ductwork or changing its route.
For a rental or business, identify who is authorized to approve the estimate. Share building access requirements and occupied hours when arranging the work. Coolerado accepts residential and commercial inquiries; the specific application and availability are confirmed with the team.
Understand the proposed cleaning level
Coolerado does not assign a cleaning level from the city name or the age of the property alone. Discuss the condition and the work being recommended. Ask which observations support the scope, and whether there are areas that cannot be assessed or reached.
If photographs are used in the discussion, ask which section is shown. An image of one opening is useful context for that area; it does not describe every branch. The proposal should explain the job beyond a single photograph.
We offer different cleaning levels because every system starts in a different condition. The work should match what is actually there.
Request a free estimate in four steps
- Share the location. Include your city and ZIP code so Coolerado can confirm coverage.
- Describe the request. Explain what you have noticed, the property type, and the number of systems if known.
- Mention related work. Include dryer vent cleaning, repairs, or upcoming renovations that you want to discuss.
- Review the proposed scope. Confirm the work, price, and arrangements directly with the team before a visit is booked.
Use the form below for an estimate inquiry or the appointment planner to include a preferred day and time. A submitted request does not automatically reserve an appointment or commit you to a quoted price. Coolerado follows up to confirm the details.
You can also call (720) 222-4706 or send a text. Please leave payment details out of the request form.
Questions about pricing
Are the prices shown in older photo graphics current?
Confirm a current estimate directly with Coolerado. A promotional graphic in the photo library should not be treated as an active offer or as a quote for your property.
Is dryer vent cleaning included?
Ask for it explicitly. The dryer exhaust is separate from the heating and cooling ducts. See the dryer vent cleaning page and confirm the scope and pricing for both services if you want them together.
Can I get a quote without knowing the vent count?
Start with the information you have. Tell the team which details are uncertain so they can discuss what is needed for the estimate. Do not enter difficult spaces or move heavy equipment just to collect a count.
Does choosing a higher cleaning level fix every comfort problem?
No such outcome is promised here. Describe heating, cooling, or airflow concerns separately. Some issues may need equipment attention or duct repairs rather than a different cleaning scope.
