Trusted Air Duct Cleaning for Denver Homeowners
Air duct cleaning in Denver typically costs between $300 and $700 for a full residential system, depending on square footage, the number of vents, and how long it’s been since the last cleaning. Most homes in Denver need it every 3 to 5 years, though houses near construction zones, homes with pets, or properties that survived a wildfire smoke season often need it sooner. Haven has connected Denver homeowners with independently owned and operated air duct cleaning brands since 1998, and every one of them is held to the Haven Standard: five published clauses that cover the price, the person, and the evidence before any work begins. If you’re breathing dust, waking up congested, or noticing that your vents look like they’re wearing gray sweaters, call (970) 725-6025 and a live person will answer, 24/7.
Key Takeaways:
- Denver air duct cleaning runs $300-$700 for most homes; the price is on the page in dollars before anyone arrives.
- Every Haven brand publishes the license number of the crew assigned to your job, with background checks already complete.
- You get photographic evidence of what was found inside your ducts, not a technician’s verbal summary.
- The Haven Standard applies the same five clauses whether the job is an air duct cleaning or a full ADU build.
What Our Air Duct Cleaning Service Includes
Ten home-service brands. One standard. When you book air duct cleaning through Haven in Denver, you’re getting a service held to the identical five clauses that govern every trade in the family, from chimney cleaning to locksmith work. Here’s exactly what the service covers.
Supply Vent and Return Register Cleaning
Registers collect dust, pet hair, and the fine gray Denver particulates that blow in every time a window opens during our dry, windy springs. Technicians remove each register, clean both sides, and vacuum the visible duct opening before addressing the main lines. You’d be surprised how much airflow improves just from clearing the vents you can see.
Main Supply and Return Duct Cleaning
This is the core of the job. Using negative-pressure equipment and rotary brush agitation, the technician works through each trunk line and branch run to dislodge dust, debris, and whatever has been accumulating since the home was built or the last cleaning occurred. In Denver’s Front Range climate, that debris often includes fine silt and construction dust that settled during the 2015-2025 building boom.
Blower Motor and Fan Cleaning
Your furnace blower pushes air past everything it carries. If the blower wheel is caked with dust, it works harder, runs hotter, and moves less air. The technician accesses the blower compartment, cleans the fan blades, and documents the before and after condition with photos that go into your service report.
Evaporator Coil Inspection
If your Denver home has central air conditioning, the evaporator coil sits in the airstream above the furnace. A dirty coil restricts airflow, reduces cooling efficiency, and becomes a damp surface where mold can grow. The technician inspects the coil, photographs what they find, and discusses whether cleaning is warranted based on the evidence, not an upsell script.
Filter Housing and Filter Replacement
Every duct cleaning should end with a fresh filter. The technician checks the filter housing for fit and bypass gaps, then installs a new filter appropriate for your system. You’ll get a photo of the old filter next to the new one, and a note on the report about the recommended replacement interval for your specific Denver home, which often runs shorter during wildfire smoke season and spring pollen.
Whole-System Sanitization (Optional Add-On)
After mechanical cleaning, some Denver homeowners request an antimicrobial fogging treatment that addresses bacteria and mold spores inside the ductwork. This is a separate line item, quoted in writing before the work proceeds, and never pushed at the door. Clause 5 of the Haven Standard means no upsells, period; the option is presented in the estimate, not discovered on an invoice.

Brands We Service for Air Duct Cleaning
Ductwork doesn’t carry a brand name the way a garage door opener or a window frame does, but the systems those ducts connect to sure do. Our Denver technicians work on homes equipped with a full range of HVAC equipment, and the cleaning process adapts to the system rather than the sticker on the cabinet.
We regularly service homes with LiftMaster connected garage door systems, where the garage often shares air with the house and the accumulated dust from door operation migrates into adjacent duct runs. We’ve also cleaned ductwork in homes featuring Chamberlain garage door openers and Craftsman equipment, where the mechanical activity in attached garages introduces particulates that eventually find their way into the return side of the HVAC system. Whether your home has Raynor hardware, LiftMaster equipment, or any other make, the cleaning protocol is the same: document what’s found, clean what’s there, photograph the results.
Before
AfterSigns You Need Air Duct Cleaning Right Now
- Dust returns within days of cleaning. If you dust the living room on Saturday and by Wednesday the shelves look like they’ve been snowed on, your ducts are likely recirculating dust every time the blower kicks on. Denver’s arid climate means that dust stays airborne longer than it does in humid regions, making the recirculation loop more visible.
- Your energy bills climb without explanation. A restricted duct system forces the blower to work harder against higher static pressure, which draws more electricity and shortens the life of the motor. When the ducts are clean, air moves freely and the system runs closer to its designed efficiency.
- You smell something stale or musty when the heat or AC first starts. That odor is often dust, pet dander, and sometimes microbial growth that has settled in the ductwork during the off-season. In Denver’s shoulder seasons, the system sits idle for weeks, giving whatever is in the ducts time to develop.
- Visible dust or debris blows from the registers when the system starts. If you can see particles puffing out of a supply vent when the furnace kicks on, the ducts are delivering more than conditioned air. This is the most direct evidence that a cleaning is overdue.
- Anyone in the home has unexplained allergies, congestion, or respiratory irritation. Ducts that haven’t been cleaned in years can circulate dust mites, pet dander, and pollen collected across multiple seasons. Denver’s high pollen counts in spring and the wildfire smoke events of recent summers make this worse, and the duct system becomes the reservoir that keeps reintroducing those irritants.
Our Air Duct Cleaning Process - Step by Step
- 1
Scoped inspection and written price. The technician arrives during the window you were given, introduces themselves by name, and conducts a visual inspection of the system including a look at the return duct, the supply plenum, and the blower compartment. You receive a written price for the cleaning before any work begins, per Clause 1 of the Haven Standard. If the inspection reveals something beyond the original scope, it’s documented and priced separately with your approval, never added silently to the invoice.
- 2
System protection and negative pressure setup. The technician seals all supply registers with temporary covers and connects a high-powered negative pressure collection unit to the main duct system. This creates a vacuum that pulls loosened debris into a sealed containment system rather than blowing it back into your Denver home.
- 3
Mechanical agitation of all duct runs. Using rotary brushes and air whips, the technician agitates each branch line and trunk duct to break loose accumulated dust, debris, and biological material. The negative pressure immediately captures dislodged material at the source. In Denver homes with long horizontal runs common in ranch-style construction, extra time is spent on the far reaches of the system where debris settles and compacts.
- 4
Component cleaning and photographic documentation. The blower motor, fan blades, evaporator coil (if present and accessible), and filter housing are cleaned and inspected. The technician photographs the before and after condition of each major component, and those photos go into a written report you receive at the end of the visit, along with any observations about system condition or recommendations for future maintenance.
- 5
Final walkthrough and service report. The technician removes the protective covers, reinstalls the registers, installs a fresh filter, and walks you through the system. You’ll see the photos, understand what was found, and have a written record of exactly what was done, all before any payment is processed. The work is covered by the 365-Day Done Right Promise: if it wasn’t done right, it’s made right within a year.
How Much Does Air Duct Cleaning Cost in Denver?
A typical air duct cleaning for a 2,000 to 2,500 square foot home in Denver runs $300 to $700, with most jobs landing between $400 and $550. Smaller condos and townhomes in areas like Capitol Hill or the Highlands often fall between $250 and $400, while larger homes in neighborhoods like Hilltop or Cherry Creek with multiple HVAC systems can exceed $700. The price is driven by the number of vents, the number of systems, the length of the duct runs, and the level of contamination present when the technician opens the first register.
What affects the price: access to the air handler (crawlspace versus basement versus attic), the number of supply and return registers, whether the home has one system or two, and whether any sections of ductwork require special attention due to construction debris or water damage. What does not affect the price at a Haven brand: how nice the technician thinks your house is, how long you’ve lived there, or whether you seem like the type who might pay more. The price is on the page, in dollars, before anyone arrives.
A free estimate includes a visual inspection of accessible ductwork, a written scope of work, and a firm price. If the technician recommends sanitization or coil cleaning, it’s listed as a separate line item with its own dollar figure, and you decide before any of it happens. No one works past the agreed scope without your explicit sign-off.

Frequently Asked Questions - Air Duct Cleaning in Denver
Air duct cleaning is the mechanical removal of dust, debris, pet dander, and biological contaminants from the supply and return ductwork of your home’s HVAC system. It includes cleaning the registers, the main duct runs, the blower motor and fan, and inspecting the evaporator coil. In Denver, where dry air keeps particulates suspended and seasonal wildfire smoke adds to the load, duct cleaning is a maintenance task most homes need every three to five years. Call (970) 725-6025 for a free estimate and we’ll tell you plainly whether your system needs it.
A typical air duct cleaning in a Denver home takes 2 to 4 hours depending on the size of the home, the number of systems, and the amount of contamination present. Larger homes with two HVAC systems or heavily soiled ductwork may take 5 to 6 hours. The technician will give you an accurate time estimate during the inspection, before work begins, and you’ll receive the written price at the same time.
Most Denver homes pay between $300 and $700 for a complete air duct cleaning, with the average around $450 to $550. The final price depends on square footage, vent count, and system accessibility. Every Haven brand quotes a firm price in writing before any work starts, so the number you see on the estimate is the number you pay. Call (970) 725-6025 and a live person will walk you through what to expect.
We routinely clean ductwork in Denver homes equipped with LiftMaster, Chamberlain, Craftsman, and Raynor garage door systems, because attached garages share air with the living space and introduce dust into the return side of the HVAC system. The cleaning protocol is the same regardless of the equipment brand: inspect, agitate, capture, document. If you’re also experiencing garage door issues in Denver, the Haven family includes a garage door brand held to the same five clauses.
Air duct cleaning is a scheduled service, not a same-day emergency repair, but the person who answers your call can tell you the next available window and often accommodate urgent requests within 24 to 48 hours. If you’ve experienced smoke damage, water intrusion, or a pest problem that contaminated your ducts, let us know when you call and we’ll prioritize your home. The phone is answered by a live person around the clock at (970) 725-6025.
Every Haven brand is bound by the 365-Day Done Right Promise: if the work wasn’t done right, it gets made right within a full year, no arguments and no fine print. That’s the same clause whether the job is an air duct cleaning or a chimney cleaning in Denver. The guarantee is part of the Haven Standard, and it’s published, not buried in a terms page footnote.
Clear a path to the furnace or air handler so the technician can access the system, and move any furniture or belongings away from at least a few of the registers if possible. Secure pets in a comfortable room away from the work area. The technician will bring drop cloths and protective equipment, and will walk you through what to expect at the start of the appointment. Everything else is handled by the crew.
