Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterAir Duct Cleaning in Northglenn, CO
Dryer vent cleaning in Northglenn runs $129-$189 for a standard single-story ranch, and the reason most homes here need it has less to do with laundry volume than with the way Northglenn was built. The city went up almost entirely between 1960 and 1975 as a planned community, so the housing stock is remarkably uniform: single-story and split-level ranches with full or partial basements, original sheet-metal duct systems, and laundry rooms that vent through decades-old pipe. Call (806) 606-6902 and we’ll give you a written price before any work begins, backed by a photo record of every run.
Why Northglenn Homes Are Different
Northglenn sits on the open high plains at roughly 5,400 feet, fully exposed to upslope wind events that carry fine silicate dust off the eastern Colorado plains. Add recurring wildfire smoke from the mountain corridors to the west, and duct systems here load with particulate faster than in more sheltered parts of the metro. The housing stock compounds the problem. Most homes are ranches built between 1960 and 1975, and their ductwork is trunk-and-branch sheet metal routed through basements where original mastic and tape seals have dried and cracked over five or six decades. Basement particulate, concrete dust, storage-area debris, and laundry-room lint get drawn straight into the return air stream through those failed connections.
The pattern our technicians see on nearly every street in Northglenn is this: a replacement furnace, sometimes only a few years old, bolted onto the original 1960s duct plenum and trunk lines. Homeowners reasonably assume their system is newer than it is. The furnace is. The ducts are not. That mismatch between appliance age and duct age means a cleaning or sealing job here is rarely just maintenance. It’s usually the first time those ducts have been touched since the Nixon administration, and the camera shows it before we do anything else.
Our Main Northglenn Services
Most Northglenn homeowners call us about two things: the full air duct cleaning that addresses decades of accumulated dust in those original 1960s trunk lines, and the HVAC cleaning that gets the blower, coil, and plenum back to the condition the furnace manufacturer expected to see.
Air Duct Cleaning in Northglenn
In Northglenn, a full air duct cleaning means opening the original sheet-metal trunk-and-branch system in a 1960s or early-1970s ranch and removing what has settled there since the home was built. We photograph the inside of every run before and after, and the written price covers the whole system, not a per-vent upcharge that grows once the truck is parked. Air Duct Cleaning in Northglenn typically takes half a day on a standard ranch with a basement.
HVAC Cleaning in Northglenn
Because so many Northglenn homes have newer furnaces on original ductwork, HVAC cleaning here usually reveals a blower wheel and evaporator coil coated with the same decades-old dust the ducts carry. We clean the blower assembly, coil, plenum, and condensation pan, then show you the before and after photos from inside the cabinet. HVAC Cleaning in Northglenn is scheduled as a separate visit from duct cleaning so each system gets the time it needs.

BeforeAfterDryer Vent Cleaning in Northglenn
Dryer vent cleaning in Northglenn is $129-$189 for most single-story ranches, and the job here is shaped by two facts: the original laundry vent piping in these 1960s and 1970s homes was never designed for modern dryer airflow, and the plains dust that settles everywhere in Northglenn also settles inside the vent run. Every foot of that pipe adds resistance, and resistance is what drives lint accumulation, longer dry times, and eventually a fire hazard. Our full service hub for Dryer Vent Cleaning covers the range, but the Northglenn reality is specific enough that it deserves the detail below.
Vent Cleaning
Signs you need it
Clothes take more than one full cycle to dry, the dryer exterior runs hotter than it used to, or you can see lint at the exterior vent hood.
What it costs in Northglenn
Standard vent cleaning runs $129-$189 depending on the run length and whether the vent exits through the roof or a side wall.
How we do it
We run a rotary brush the full length of the vent with negative-pressure extraction pulling loosened lint into a HEPA-filtered vacuum, then camera-verify the run is clean from both ends.
Bird Guard Installation
Signs you need it
You hear birds or rustling near the exterior vent hood, or you can see nesting material protruding from the flap.
What it costs in Northglenn
Installing a guardsman-grade vent hood with integrated bird screen runs $89-$150 including the old hood removal.
How we do it
We remove the old hood, clear any nesting debris from the vent opening, and mount the new screened guard to code clearance while keeping the flap free to open.
What Dryer Vent Cleaning Costs in Northglenn
| Item | Typical range in Northglenn |
|---|---|
| Standard vent cleaning (single-story, side-wall exit) | $129-$159 |
| Extended run or roof-exit cleaning | $159-$189 |
| Bird guard and exterior hood replacement | $89-$150 |
How often should a dryer vent be cleaned in Northglenn?
Every 12 to 18 months for most households. The plains dust and wildfire smoke that settle in Northglenn vents mix with lint, so the interval runs shorter here than in more sheltered metro locations.
Why does my dryer vent clog faster in Northglenn than my previous home?
Elevation and exposure. Northglenn sits at 5,400 feet on open plains, where upslope wind events carry fine silicate dust directly into exterior vents. Your previous home likely sat lower or in a more developed buffer. Call (806) 606-6902 for an exact quote; estimates are free.
Duct Repair & Sealing in Northglenn
Duct repair and sealing in Northglenn is $145-$350 for most jobs, and the work here follows a predictable script: cracked mastic at the trunk joints, separated branch connections, and tape that stopped holding a seal decades ago. The original 1960s sheet-metal in these ranches was sound at install, but half a century of basement humidity and temperature cycling has loosened it everywhere. Our Duct Repair & Sealing page covers the full scope; below is what the work looks like in Northglenn specifically.
Duct Sealing
Signs you need it
Rooms at the end of the line never reach the same temperature as the rest of the house, or your utility bill runs high while the system struggles.
What it costs in Northglenn
Sealing accessible trunk-and-branch connections runs $145-$350 depending on how many joints need mastic and re-taping.
How we do it
We locate each leak by hand and with a smoke pencil, then reseal every joint with mastic and embedded mesh tape, not vinyl tape.
Metal Duct Repair
Signs you need it
You find sections of the basement trunk line dented, disconnected, or resting on the floor with visible gaps at the seams.
What it costs in Northglenn
Repairing or replacing a damaged sheet-metal section runs $185-$350 per section based on length and access.
How we do it
We cut out the damaged section, fabricate a replacement to match the original gauge, and seal both end connections with mastic for an airtight fit.
What Duct Repair & Sealing Costs in Northglenn
| Item | Typical range in Northglenn |
|---|---|
| Sealing accessible duct joints and seams | $145-$250 |
| Metal duct section replacement | $185-$350 |
| Mastic sealant application, full accessible system | $250-$350 |
Can you seal ducts from the inside without cutting into drywall?
Yes, for the trunk-and-branch systems in most Northglenn basements. Accessible sheet-metal runs get a full exterior seal. We only recommend internal sealing methods for concealed runs we can reach through existing openings.
Why do my ducts leak if they look fine from the outside?
The most common culprit in Northglenn homes is cracked mastic at the joints where the original material has dried and separated from decades of thermal cycling. The gap is often invisible until we run a smoke pencil along the seam. Call (806) 606-6902 for an exact quote; estimates are free.
Air Quality & Sanitizing in Northglenn
Air quality and sanitizing work in Northglenn runs $195-$695 depending on the system and scope, and the demand here tracks directly to the high-plains environment. Fine silicate dust and recurring wildfire smoke penetrate homes through every door and window, then circulate through duct systems that often show six decades of accumulated particulate. Our Air Quality & Sanitizing page covers the full menu; the Northglenn specifics follow.
UV Light Installation
Signs you need it
You see visible microbial growth on the coil or plenum, or occupants have persistent respiratory irritation that improves when they leave the house.
What it costs in Northglenn
A Honeywell UV lamp installed at the coil runs $395-$695, including mounting, wiring, and verification of lamp output.
How we do it
We mount the UV lamp at the evaporator coil where the lamp’s line of sight covers the coil face, then verify output with a UV meter before finish.
Odor Removal
Signs you need it
Musty, stale, or lingering smoke odor returns within hours of airing the home, or the smell is strongest at the registers when the blower runs.
What it costs in Northglenn
Odor removal paired with a system clean runs $195-$350 for most ranch-style homes in Northglenn.
How we do it
We clean the duct surfaces first, then apply an evaporative sanitizer to all accessible duct and plenum surfaces, letting it dry fully before restarting the system.
What Air Quality & Sanitizing Costs in Northglenn
| Item | Typical range in Northglenn |
|---|---|
| Odor removal with system treatment | $195-$350 |
| UV light installation at the coil | $395-$695 |
| Bacteria sanitizing, full accessible system | $250-$450 |
Will a UV light help with wildfire smoke inside my Northglenn home?
UV light addresses microorganisms, not smoke particles. For smoke, the right move is a full duct cleaning combined with filtration upgrades. We’ll tell you if a UV lamp is not the correct solution for what you’re experiencing.
How do I know sanitizing actually happened?
You’ll see it in the photo record. We photograph the coil, plenum, and duct surfaces before and after the sanitizing treatment, and the photos are delivered as part of the standard job record. Call (806) 606-6902 for an exact quote; estimates are free.
