AfterAir Duct Cleaning in Denver, CO
Dryer vent cleaning in Denver runs $125-$210 for most single-family homes, and the job takes under two hours when the vent run is standard. Nearly every 1950s-1970s ranch in Harvey Park, Barnum, and Westwood still routes its dryer exhaust through original galvanized duct, and Denver’s single-digit winter humidity turns lint into a brittle, compacted layer that compresses against the pipe wall. That buildup is the leading cause of slow drying times in this city, and it cannot be resolved by cleaning the lint trap alone. If you’re calling about a dryer that runs two cycles per load, call (806) 606-6902 and we’ll give you a written price before we schedule.
Why Denver Homes Are Different
Denver’s position at the base of the fire-prone Front Range means wildfire smoke, most infamously from the December 2021 Marshall Fire, drifts into duct systems across the metro and deposits fine particulate that ordinary filter changes never touch. Because the city also sits in a high-desert basin where temperature inversions trap the brown cloud of Front Range pollution, return ducts breathe dirtier air year-round, not just during fire season. This is a chronic loading problem, not an occasional one.
The housing stock compounds it. Post-WWII ranch homes in neighborhoods like Harvey Park, Barnum, and Montbello still run their original galvanized sheet-metal ductwork through unfinished basements. That metal is now 50 to 70 years old, and most of these systems have never been professionally cleaned. Newer infill construction and Central Park development uses flex duct in tight soffits, which cracks under Denver’s extreme dryness and 40-to-70-degree daily temperature swings. Every winter heating cycle draws more dust into those cracks and distributes it through every register.
With roughly 14 inches of annual precipitation, Denver’s air leaves fine mineral dust and allergens suspended longer than humid markets do. Return ducts in this city collect particulate that clumps and compacts instead of flushing out. A home that merely “has dusty vents” almost always has a deeper problem in the return plenum, and the camera shows it in the first ten minutes.
Our Main Denver Services
Two services generate most of the calls our Denver office fields. Both begin with a written price and end with a documented photo record of the interior of every duct run.
Air Duct Cleaning in Denver
Whole-system air duct cleaning on a Denver ranch typically runs $285-$540, depending on the number of runs and whether flex duct is present. After the Marshall Fire and subsequent smoke seasons, we’ve seen return plenums with smoke-oil residue that vacuum extraction alone cannot remove. This service includes the before-and-after photo record showing exactly what came out. For the full Denver scope and pricing breakdown, see Air Duct Cleaning in Denver.
HVAC Cleaning in Denver
HVAC cleaning in Denver focuses on the blower motor, evaporator coil, and plenum, where Denver’s chronic dust loading accumulates heavily between seasonal cycles. A furnace that cycles repeatedly during a 50-degree daily temperature swing pulls more air, and more particulate, through the coil. This service covers what a duct-only cleaning leaves behind. Full Denver details and pricing are on our HVAC Cleaning in Denver page.

BeforeAfterDryer Vent Cleaning in Denver
Dryer vent cleaning in Denver removes the compacted lint that forms inside exhaust ducts when low-humidity air bakes loose fibers into a hardened layer along the pipe wall. In older ranch homes with long vertical vent runs through the roof, this compaction reduces airflow to the point that moisture and heat stay trapped inside the dryer. Our Dryer Vent Cleaning service documents the interior before and after with camera photos, so you see the exact obstruction and its removal.
Denver’s dry climate means lint does not stay loose and fluffy; it bakes onto the galvanized duct surface and often requires mechanical brushing to dislodge. Homes in Westwood and Barnum, where vents run through unheated basements and exterior walls, are especially prone to condensation at the terminal end that turns lint into a thick, papery crust. Lint screens only catch a fraction of the material that reaches the vent, so a clean screen is no indication of a clean run.
Dryer Vent Inspection
Signs you need it
The dryer is taking longer than one full cycle to dry a normal load and the exterior vent flap barely opens while the machine runs.
What it costs in Denver
A camera inspection runs $35-$75 and is often credited toward the cleaning if we proceed the same visit.
How we do it
We run a camera from both the dryer connection and the exterior terminus, showing you every obstruction location before we touch the line.
Vent Cleaning
Signs you need it
The dryer’s lint trap is full after every cycle and clothes come out warm but damp, meaning heat is present but airflow is not.
What it costs in Denver
Full vent cleaning on a standard Denver home runs $125-$210, depending on run length and access.
How we do it
We mechanically agitate the entire run with a rotary brush while negative-pressure extraction captures dislodged lint at the dryer connection.
Lint Removal
Signs you need it
A hard, dense accumulation visible at the exterior vent or a burning smell when the dryer runs on high heat.
What it costs in Denver
Stubborn removal work falls within the $125-$210 vent cleaning range, with no separate surcharge for difficult access.
How we do it
We use graduated brush sizes matched to the duct diameter, working from the largest obstruction toward the wall until the full bore is clear.
Vent Rerouting
Signs you need it
Your current vent route exceeds the dryer manufacturer’s maximum equivalent length, often a problem in Denver basements where the exterior wall is a long horizontal run away.
What it costs in Denver
Rerouting typically runs $180-$420, depending on the new route length and whether roof or wall penetration is required.
How we do it
We write a new route plan with measurement math included, then replace rigid or semi-rigid duct along the shorter path, sealing every joint.
Bird Guard Installation
Signs you need it
Nesting material is visible at the exterior vent cap or you’ve heard birds near the vent on a second-story wall.
What it costs in Denver
A galvanized or stainless guard installed at the terminus runs $75-$150, including removal of any existing nest material.
How we do it
We remove existing nesting debris, verify the flap operates freely, then secure the guard so the vent still exhausts at full volume.
What Dryer Vent Cleaning Costs in Denver
| Item | Typical range in Denver |
|---|---|
| Camera inspection | $35-$75 |
| Full vent cleaning | $125-$210 |
| Vent rerouting | $180-$420 |
| Bird guard installation | $75-$150 |
How often should a dryer vent be cleaned in Denver?
Once per year in most Denver homes. Older ranch houses with long vertical runs may need it every 8-10 months, and homes that saw wildfire smoke exposure should schedule a check sooner. Call (806) 606-6902 for a written quote.
Why does my dryer take longer to dry in winter?
Denver’s cold, dry winter air can’t hold as much evaporated moisture, and a partially obstructed vent makes the problem worse by trapping humid exhaust inside the machine. A clean vent restores manufacturer-specified drying times. Call (806) 606-6902 for a written quote.
Duct Repair & Sealing in Denver
Duct repair and sealing in Denver addresses the leaks and cracks that form in aging galvanized ductwork and brittle flex duct when 50-degree daily temperature swings force expansion and contraction cycles. Older ranch homes throughout Harvey Park, Barnum, and Montbello lose conditioned air at failed joints, elbow seams, and rusted plenum connections long before a full replacement is needed. Our Duct Repair & Sealing service restores the system’s integrity without tearing out interior walls.
In Denver’s dry climate, duct tape and older mastic crack and peel within a few years, opening gaps that pull in crawlspace dust and basement air. Flex duct in newer Central Park and Stapleton homes splits at the inner liner when the material dries out, and these splits are invisible until the outer jacket is opened. We document every repair with before-and-after photos, so the written quote matches the work performed.
Duct Sealing
Signs you need it
Rooms farthest from the furnace stay noticeably cooler in winter and the system runs constantly without reaching the set temperature.
What it costs in Denver
Sealing accessible joints and seams on a typical Denver duct system runs $240-$600, depending on the number of leaks found.
How we do it
We identify every leak with a pressure test, then apply mastic or aluminum tape at each failed seam and retest to confirm the seal.
Flex Duct Repair
Signs you need it
Rooms served by flex duct have weak airflow while others are strong, or you see crushed sections in attic or soffit access points.
What it costs in Denver
Replacing a cracked or collapsed flex-duct run costs $190-$550 per run, including material and connection sealing.
How we do it
We cut out the failed section, install the correctly sized replacement, and seal both connections with mastic before re-insulating the run.
Metal Duct Repair
Signs you need it
Visible rust has eaten through a section of galvanized duct, or a joint has separated in an unfinished basement and dust is entering the system there.
What it costs in Denver
Patch or section replacement on metal duct runs $150-$450 per section, based on gauge and access difficulty.
How we do it
We cut out the damaged metal, fit a matching galvanized replacement, and seal every seam so the repaired section is airtight.
Duct Insulation
Signs you need it
Ducts run through an unheated basement or crawlspace and form condensation on the outer surface during humid summer weeks.
What it costs in Denver
Insulating accessible duct runs costs $4-$8 per linear foot, with the total depending on how many runs are exposed.
How we do it
We wrap each run with fiberglass insulation to the correct R-value for Denver’s temperature swings, then secure and seal the vapor barrier.
What Duct Repair & Sealing Costs in Denver
| Item | Typical range in Denver |
|---|---|
| Duct sealing (full system, accessible) | $240-$600 |
| Flex duct replacement | $190-$550 per run |
| Metal duct patch or section | $150-$450 per section |
| Duct insulation | $4-$8 per linear foot |
How do I know my ducts are actually leaking?
Most Denver homes lose 20-30% of conditioned air through duct leaks before a repair. A pressure test measures the loss in CFM, and we write the number on the quote. Call (806) 606-6902 for a written quote.
Is duct sealing worth it in Denver’s climate?
Yes. With 50-degree daily temperature swings, conditioned air escaping into unconditioned spaces forces the HVAC system to cycle more often, accelerating wear and increasing utility use. Sealing pays back fastest in older ranch homes. Call (806) 606-6902 for a written quote.
Air Quality & Sanitizing in Denver
Air quality and sanitizing in Denver targets what remains after cleaning: the smoke oils, microbial growth, and embedded odor that ordinary vacuum extraction cannot remove from duct surfaces and plenum liners. After the Marshall Fire, homes across the western suburbs and downwind neighborhoods dealt with smoke residue that returned with every heating season. Our Air Quality & Sanitizing service treats the duct lining itself, leaving a documented record of exactly what was applied and where.
Denver’s chronic brown-cloud inversions mean outdoor particulate enter the system year-round, while the dry climate keeps mold at bay in most homes but leaves organic debris ready to bloom during the rare wet spell. Encapsulants and antimicrobial treatment address both the residue and the source. Equipment from Abatement Technologies and Guardsman is used on most sanitizing jobs, and we name the exact product on the written scope.
Mold Treatment
Signs you need it
Visible microbial growth is present on duct surfaces or a musty smell returns within days of cleaning.
What it costs in Denver
Mold treatment for a standard Denver duct system runs $300-$800, depending on the extent of affected surface area.
How we do it
We apply an EPA-registered antimicrobial directly to affected surfaces, allow the dwell time the label specifies, then document the treatment.
Odor Removal
Signs you need it
A persistent smoke, pet, or cooking odor recirculates through the house every time the blower engages.
What it costs in Denver
Odor encapsulation and treatment runs $200-$500, based on system size and odor severity.
How we do it
We clean the accessible surfaces first, then fog or wipe an encapsulant designed for smoke and organic odor into the duct lining.
UV Light Installation
Signs you need it
Family members have recurring allergy symptoms indoors, and visible growth around the evaporator coil suggests biological material in the plenum.
What it costs in Denver
Installing a UV-C lamp in the supply plenum runs $450-$1,100, including lamp, mounting, and electrical connection.
How we do it
We mount the UV lamp upstream of the coil using a manufacturer-specified bracket, wire it to the blower circuit, and confirm operation.
Air Purifier Install
Signs you need it
Denver’s brown-cloud periods leave your household with persistent respiratory irritation even when filters are changed monthly.
What it costs in Denver
Whole-home air purifier install runs $600-$1,500, depending on the unit and whether a dedicated circuit is required.
How we do it
We select a unit sized to your square footage, install it in the return plenum, wire it, and replace the media at the recommended interval.
What Air Quality & Sanitizing Costs in Denver
| Item | Typical range in Denver |
|---|---|
| Mold treatment | $300-$800 |
| Odor removal | $200-$500 |
| UV light installation | $450-$1,100 |
| Air purifier install | $600-$1,500 |
Will sanitizing get rid of smoke odor permanently?
When applied correctly to cleaned surfaces, an encapsulant seals smoke oils into the duct lining and prevents them from off-gassing. If odor returns within the year, the 365-Day Done Right Promise covers re-treatment. Call (806) 606-6902 for a written quote.
Is UV light installation safe for my family?
Yes, when installed inside the duct with the lamp shielded from direct line of sight. The unit operates only when the blower runs, and access panels remain sealed. Call (806) 606-6902 for a written quote.
