Dust puffing from the vents
Built-up dust in the runs gets pushed out when the system starts. Cleaning the runs takes that dust out at the source.

Air Duct Cleaning in Denver: What the Job Involves
Air duct cleaning is removing built-up dust and debris from the accessible supply and return runs, register boots, and returns in your home, using a vacuum and brush tools. It is a cleaning job, not a repair — it takes out what has collected in the ducts over the years.
Ducts collect dust, pet hair, and debris, and Denver's construction dust and cottonwood add to it. After a renovation, the ducts can hold drywall dust and sawdust that then circulates every time the system runs. Cleaning takes that material out of the runs it can reach. It does not fix leaks, repair damaged ducts, or remove mould — those are different jobs, and we say so plainly.
- ✓ Accessible runs cleaned
- ✓ Registers and returns wiped
- ✓ Debris vacuumed, not pushed around
- ✓ Honest limits, stated plainly
What's included
What Our Air Duct Cleaning Includes
A cleaning visit covers the ductwork we can reach and the parts that collect the most debris. Here is what we do.
✓
Supply run cleaning
We clean the accessible supply runs with a vacuum and brush tools, taking out the dust and debris that has built up on the duct walls.
✓
Return run cleaning
We clean the return runs and returns, which carry the dirtiest air in the system and collect the most material.
✓
Register and boot cleaning
We remove the registers, clean the boots behind them, and wipe the registers before they go back.
✓
Debris containment
We work with the system off and the vacuum running, so the dust we loosen is pulled out rather than pushed into the rooms.
✓
Visual check as we go
We look inside the runs as we clean and note any leaks, damage, or disconnected sections we find, so you know about them.
✓
Filter change
We fit a fresh filter at the end of the visit, so the system starts clean and stays that way longer.
How it works
Our Air Duct Cleaning Process
01
Walk the home
We look at the duct layout, count the registers and returns, and note which runs are accessible and which are not.
02
Protect the rooms
We lay down drop cloths at the registers and set up the vacuum, so the work stays contained.
03
Clean run by run
We work through the supply and return runs with brush and vacuum tools, loosening and pulling out the built-up material.
04
Clean the registers
We remove, clean, and refit the registers, and wipe down the boots behind them.
05
Check and report
We fit a fresh filter, run the system briefly, and leave a note of what was cleaned and anything we found along the way.
Tools & methods
Tools and Methods We Use
Vacuum and brush tools that pull debris out of the ducts instead of pushing it around.
Duct vacuum
A high-volume vacuum that pulls loosened dust and debris out of the runs as we work.
Rotary brush tools
Brushes that loosen built-up dust from duct walls so the vacuum can take it out.
Inspection camera
Lets us see inside the runs before and after cleaning, so the result is visible.
Air nozzle
Compressed air that dislodges debris in tight spots the brush cannot reach.
Drop cloths and covers
Protect floors and furniture at each register while we work.
Register tools
Remove and refit registers without damaging the finish around them.
Typical jobs
Before and After
Dust after a renovation
Before
A kitchen renovation left drywall dust in the ducts, and every time the system ran, a fine haze settled on the furniture.
After
After the runs were cleaned and a fresh filter fitted, the dust at the vents stopped and the house stayed clean between dustings.
A system never cleaned
Before
A home's ducts had never been cleaned in twenty years. The returns were thick with dust and pet hair, and the air felt stale when the system ran.
After
Cleaning the runs and returns took out years of build-up, and the air from the registers felt fresher.
Debris in a new-to-them home
Before
A family moved into a home and found the vents full of debris from the previous owner's pets and a long-empty house.
After
A full cleaning of the accessible runs gave them a clean start, and the vents have stayed clean since.
Problems we solve
Problems Air Duct Cleaning Solves
Duct cleaning is a specific job for a specific problem. Here is when it helps — and when it does not.
Ask a pro →↗
Debris after a renovation
Drywall dust, sawdust, and construction debris settle in the ducts during a remodel. Cleaning removes it before it circulates for months.
Stale air when the system runs
Years of build-up in the returns can leave the air feeling stale. Cleaning the returns and fitting a fresh filter helps.
What cleaning cannot fix
Cleaning does not seal leaks, repair damaged ducts, or remove mould. If we find those problems, we tell you and talk through the right job for them.

✓ VerifiedMost homes do not need it often. After a renovation, after moving into a home with dirty ducts, or when dust is visibly coming from the vents are the usual reasons. A home with no symptoms and a filter changed on schedule may go years between cleanings.
It cannot fix leaks, repair damaged or disconnected ducts, or remove mould. It also cannot reach runs hidden behind finished walls. We tell you which runs are accessible before we start, and flag any problems we find.
It removes the dust that has built up inside the ducts, so the system stops circulating it. It will not stop dust coming in from outside or from the house itself — that is a filtration question, not a cleaning one.
It depends on the size of the home and the number of registers and returns. Most homes take a few hours. We confirm the scope after walking the duct layout.
