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.
Fast, Reliable HVAC Cleaning Across Northglenn
HVAC cleaning in Northglenn, CO typically runs $390-$680 for a full system on a ranch-style home, and the defining factor here isn’t square footage. It’s the age of the ductwork. Most Northglenn homes were built between 1960 and 1975, which means the furnace may be new but the sheet-metal ducts moving its air are often original, untouched, and leaking at the seams. Our HVAC Cleaning team works Northglenn every week, and we know what those systems look like inside. If you’re ready to see what’s actually moving through your ducts, call (806) 606-6902 for a written price before any work starts.
Why CleanRun Air Duct Cleaning Is Northglenn’s Preferred HVAC Cleaning Company
We’re not the newest name in the metro, and we don’t run coupon mailers. What we do is document everything. Founded in 2013, CleanRun Air Duct Cleaning has served over 52,000 homes across the front range, and every single job ends the same way: a written price agreed to before work begins, and a photo record of every duct run before and after, delivered with the invoice. Under Haven Standard Clause 1, no price is ever quoted over the phone as a teaser and then revised upward once the panels come off. The written price is the price.
In Northglenn specifically, that matters more than in most places. The housing stock is unusually uniform: ranch homes with basements, built during a tight 15-year window. That means our techs see the same failure patterns street after street. A 2018 furnace sitting on a 1965 plenum. Cracked mastic at every takeoff. Return ducts pulling concrete dust and laundry-room lint straight into the air stream. Local knowledge like that comes from doing the work, not from a training manual. Tomas Reyes, who leads our crews, can tell you what the camera sees in a Northglenn basement before it’s even turned on. That’s the expertise you’re paying for.
Our HVAC Cleaning Services in Northglenn

Every system we clean in Northglenn gets the same treatment: negative-pressure extraction with HEPA filtration, agitation tools matched to the duct material, and a camera inspection before and after. The full documented record is standard on every visit. Here’s where our work concentrates on Northglenn homes:
Evaporator Coil Cleaning
In a Northglenn ranch with a basement, the evaporator coil sits on top of the furnace, pulling return air through it constantly. When those return ducts leak at the original 1960s joints, the coil becomes a filter for basement dust. We routinely pull coils here that are caked with a gray paste of fine silicate dust and lint, cutting airflow and forcing the blower to work harder. Cleaning the coil isn’t a standalone job in these homes. It’s part of correcting the leak that caused the fouling in the first place.

Blower Cleaning
The blower motor and wheel collect whatever the return air brings them. In Northglenn, that means a fine, almost talcum-like dust from the open high plains, plus whatever the cracked return ducts pick up from the basement floor. A dirty blower wheel throws the motor out of balance and reduces airflow even when the coil is clean. We remove, clean, and reinstall the blower assembly as part of full-system HVAC cleaning, and we show you the before and after photos so you can see the difference.

Air Handler Cleaning
Air handler cleaning in Northglenn is where the duct age shows up most clearly. The air handler cabinet sits at the heart of the system, and on 50-to-60-year-old trunk lines, it’s pulling from every leaking joint along the way. We clean the full interior of the handler, the blower compartment, and the coil housing, then reseal the cabinet so the air it processes actually arrives clean. On split-level homes off Huron Street and in the Fox Run area, we’ve found that handler cleaning alone drops the visible dust load in the house within a week.

Condenser Cleaning
The outdoor condenser on a Northglenn home takes direct exposure to high plains wind events and wildfire smoke residue. Cottonwood from the South Platte corridor, plus fine dust that blows up off unpaved roads and open land, packs into the coil fins and forces the compressor to run hotter. We clean the condenser coil, straighten fins where needed, and check the refrigerant lines so the outdoor half of the system matches the indoor half.

AfterTrusted Brands We Service in Northglenn
Our equipment roster includes Rotobrush, Nikro, and Guardsman, along with HEPA filtration units from Abatement Technologies. That’s what we bring into your Northglenn home. But the equipment in your system matters too. Whether your furnace is a Carrier, Trane, Lennox, Goodman, or anything else, our HVAC cleaning process is designed around the ductwork delivering the air, not the badge on the cabinet. On most Northglenn homes, the ductwork predates every one of those brands, and that’s exactly why the cleaning and resealing work we do matters more than the equipment name on the blower housing.
Common HVAC Cleaning Problems We See in Northglenn Homes

Northglenn’s uniform 1960-1975 ranch stock creates the same failure modes on nearly every street. Here’s what we find most often:
- Original 1960s trunk lines with cracked mastic at every takeoff. The joints were sealed once, decades ago, and the sealant has dried and separated. Air that should be moving through the supply ducts escapes into the basement ceiling, and air that should come from a clean return register gets pulled in from wherever the gap is.
- A new furnace bolted onto a 60-year-old duct network. Homeowners assume a recent HVAC replacement means the whole system is current. It doesn’t. The ducts are still original, still leaking, and still loading with the same dust they’ve been collecting since the Johnson administration.
- Basement particulate drawn directly into the return air stream. Northglenn basements are storage, laundry, and utility spaces. Concrete dust from the floor, lint from the dryer, and fine material from open shelving all get pulled into return ducts that leak at the seams, then recirculated through the entire house every cycle.
- Fine silicate dust from open land and unpaved road exposure. Northglenn sits on the high plains, fully open to upslope wind events that push fine dust off the eastern Colorado plains. Homes near open fields at the city’s edge load faster than sheltered metro locations, and the dust is fine enough to pass through standard filters.
Pricing for HVAC Cleaning in Northglenn, CO
We don’t quote per-vent prices and we don’t run $79 offers that turn into four-figure invoices. A full HVAC cleaning on a typical Northglenn ranch home runs $390-$680, depending on system size and whether we’re also cleaning the evaporator coil, blower assembly, and condenser. Split-level homes with two systems or a basement plus crawlspace layout typically land in the $550-$850 range. The written price covers everything: negative-pressure extraction, HEPA filtration, agitation, camera verification before and after, and the documented photo record delivered at the end of the job. Under Haven Standard Clause 1, that written price is delivered before any panel comes off, and it doesn’t change. If you have a written estimate from another company, we’ll put our number next to it in writing, free of charge. Call (806) 606-6902 and you’ll have a price from us before we touch a single register.
Northglenn’s defining HVAC fact is this: nearly every home here runs ducts that are 50 to 60 years old, and most of those ducts have never been professionally cleaned or resealed. Not once. The furnace is new. The ducts are original. That gap between appliance age and duct age is the single biggest driver of the dust, the airflow problems, and the energy waste we document every week in this city. A camera inspection shows the difference in 30 seconds, and we’ll show it to you before we recommend anything.

FAQs - HVAC Cleaning in Northglenn

Every 3 to 4 years, and that’s shorter than the 5-to-7-year interval you’ll hear quoted for sheltered parts of the metro. Northglenn’s open high plains exposure, at roughly 5,400 feet elevation, means fine silicate dust and wildfire smoke particulate load into duct systems measurably faster than in areas less exposed to upslope wind events. Add in original 1960s ductwork with leaking seams pulling basement particulate, and the practical interval shortens further. If you haven’t had a camera inspection done, call (806) 606-6902 and we’ll show you what’s in there before you decide anything.
Because the filter sits at one point in the system, and the leaks are everywhere upstream of it. On most Northglenn ranch homes, the return ducts run through the basement on their way to the furnace, and those original 1960s joints are cracked open, pulling concrete dust, laundry lint, and storage-area particulate directly into the air stream after the filter. The furnace is filtering what arrives. The ducts are adding dust after the filter does its job. That’s why cleaning and resealing the return side matters as much as the supply side. Call (806) 606-6902 and we’ll put a camera on it to show you exactly where the dust is getting in.
Yes, and it comes down to access. In a Northglenn ranch with a full basement, the trunk lines and branch ducts are fully exposed in the basement ceiling, which means we can see and clean the entire system without opening walls. Split-level homes present a different challenge: the ducts between levels run through finished or semi-finished spaces, and the transitions are often sealed differently. The cleaning method is the same-negative pressure and source removal-but the resealing work is more extensive on split-levels because the joints between levels tend to separate more readily. We’ll tell you which type you have during the initial camera inspection, before we quote a price.
Yes, and given Northglenn’s exposure to smoke intrusions from the mountain corridors to the west, it’s a common part of the job. Smoke residue bonds to the fine dust already inside the ducts, creating a sticky, gray film that won’t come out with a shop vac. Our process uses HEPA-filtered negative pressure and agitation tools that break the particulate free and capture it at the machine, not in your house. The before and after photos show the difference, and the write-up includes what we found and removed. Call (806) 606-6902 to get a written price.
Everything past the first elbow. A visual check at the register shows you the first few inches of duct. A camera inspection shows you the full trunk line, the branch runs, the plenum connection, and the joints. In Northglenn’s original 1960s systems, that means seeing cracked mastic at takeoffs, separated joints, dust packed into the low points, and sometimes debris that’s been there since before the current homeowner was born. We ran a camera on a ranch off Malley Drive and found a 2019 furnace bolted onto the original 1960s trunk line with cracked mastic at every takeoff. We set up negative pressure, treated the supply and return ducts with agitation tools and HEPA filtration, and resealed the plenum connections so basement dust from the laundry and storage areas stopped being pulled into the return air. The homeowner hadn’t noticed anything wrong beyond a little extra dust. The camera showed the whole story. Call (806) 606-6902 and we’ll do the same for you.
