We’ll answer live, day or night, and give you an honest price before we book the visit.
Why Bellows Air Duct & Vent Co. Is Northglenn’s Preferred Air Duct Cleaning Company
We’ve been driving to Northglenn since 2012, back when the original 1960s master-planned neighborhoods were barely twenty years old. Today those same homes are hitting 55-60 years on their original duct systems, and we’ve cleaned enough of them to know where the problems hide before we open a single register.
Northglenn homeowners call us back because we show them what we found. Every job starts and ends with a camera inspection, so you see the debris before it leaves and the clean duct after. No claim without proof. Our 90-Day Done Right Promise means if something isn’t right, we return at no charge with no paperwork to file. That’s been our standard for 42 years, not a marketing add-on.
Our office answers calls 24 hours a day with a live person, not a voicemail tree. Most Northglenn appointments are scheduled within 24-48 hours, and our technicians are background-checked, uniformed, and arrive in marked vehicles. The price we quote on the phone is the price on the invoice. We’ve seen too many neighbors burned by bait coupons that balloon once the truck is in the driveway. We don’t work that way.
Our Air Duct Cleaning Services in Northglenn
Residential Duct Cleaning
Northglenn’s housing stock is almost entirely 1960s-1970s ranch and split-level homes built during the city’s single master-planned development push. Most have trunk-and-branch duct systems running through full basements that were installed once and rarely upgraded. Our residential cleaning addresses the whole network, from the return grille to the supply register, using HEPA-contained equipment that doesn’t blow debris back into your living space. We pay particular attention to the aging flex-duct connectors common in this era, which can tear if handled carelessly.
Commercial Duct Cleaning
Northglenn’s commercial corridors along 120th Avenue and Huron Street include retail, light industrial, and medical office spaces with duct systems that see heavier cycling than residential. We clean commercial systems after hours when possible, with the same camera-verified approach and upfront pricing. Our Rotobrush and Nikro equipment scales to larger trunk lines, and we document everything for facility managers who need records for insurance or compliance.
Supply Duct Cleaning
The supply side pushes heated or cooled air into your rooms, and in Northglenn’s 1960s ranches, these lines often run through unconditioned basement spaces where temperature swings cause condensation and debris adhesion. We clean each supply branch individually, sealing registers during the process to maintain negative pressure. In homes near the open plains east of Washington Street, we’ve found supply ducts loaded with fine mineral dust from persistent high-wind events that standard filters never catch.
Return Duct Cleaning
Return ducts pull air back to the furnace, and they’re the first collection point for household debris. In Northglenn’s older homes, returns are often undersized by modern standards, meaning air moves faster and deposits more particulate. Our return cleaning includes the main trunk, branch lines, and the return air plenum. We also inspect the filter rack for bypass gaps, common in original installations, where unfiltered air slips around the filter and loads the system.
Full System Cleaning
A full system cleaning in Northglenn means every component that moves air: supply ducts, return ducts, furnace plenum, blower assembly, and coil if accessible. Given the age of most local systems, we strongly recommend this comprehensive approach. Cleaning only half the system leaves debris to recirculate. We complete most full cleanings in one visit, and you’ll see the before-and-after footage to confirm it.
Video Inspection
This is non-negotiable for Northglenn’s 1960s housing stock. Our camera inspection reveals what cannot be seen from the registers: deteriorating fiberglass duct board, disconnected flex ducts, debris density, and structural damage. We record everything and review it with you before any cleaning begins. On a recent job in the original 1960s neighborhood off Malley Drive, we found a 55-year-old fiberglass duct board furnace plenum so brittle that the owner’s previous attempt at a DIY clean had dislodged chunks of liner into the supply registers, coating the home’s new hardwood floors with gray debris. Our video inspection confirmed the damage; we swapped the deteriorated board from the plenum to the first trunk branch before performing a gentle HEPA cleaning on the remaining galvanized ductwork. Without that camera look, we would have destroyed more than we cleaned.

Trusted Brands We Service in Northglenn
We clean duct systems connected to all major HVAC brands, and we stock parts from Aprilaire, Abatement Technologies, and Rotobrush for fast turnaround when repairs are needed alongside cleaning. Northglenn homeowners with original Carrier, Lennox, or Rheem systems from the 1960s and 1970s will find we know those legacy units well. We don’t upsell equipment you don’t need, but if your duct board plenum or flex connectors are beyond cleaning, we carry the materials to fix it properly and finish in the same visit.
Common Air Duct Cleaning Problems We See in Northglenn Homes
- Brittle fiberglass duct board plenums. Aggressive cleaning of unlined fiberglass duct board plenums common in 1960s homes can dislodge friable liner material directly into the air stream. We inspect every plenum with a camera first, and we replace deteriorated sections rather than risk shredding them.
- Torn flex-duct connectors. Skimping on a camera pre-inspection in ranch-style basements misses deteriorating flex-duct connectors that can tear under cleaning pressure. These original vinyl or foil connectors are often cracked from decades of temperature cycling in Northglenn’s unconditioned basements.
- Persistent mineral dust loading. Using generic return-duct suction without addressing the persistent fine mineral dust from high-plains wind events leaves debris settled in elderly trunk-and-branch systems. Our process includes targeted agitation and extended HEPA extraction for these conditions.
- Filter bypass and undersized returns. Original 1960s installations often used 1-inch filter racks with gaps around the edges, or returns too small for modern airflow. We identify these issues during inspection and can recommend proper sealing or upgrades that actually reduce future debris loading.

FAQs - Air Duct Cleaning in Northglenn
Because the original fiberglass duct board plenums in these homes become brittle and friable with age, and aggressive cleaning without first identifying compromised liner sections can dislodge material directly into the air stream. We’ve replaced too many damaged plenums after well-meaning owners or inexperienced cleaners skipped this step. The camera takes ten minutes and prevents a costly mistake. Call (844) 685-6342 to schedule an inspection.
Every 3-5 years for most Northglenn homes, though homes near open terrain or with original 1960s duct systems may need attention every 2-3 years. The combination of low humidity, high winds, and aging infrastructure means debris accumulates faster here than in sealed newer construction. If you can see dust buildup on your supply registers or your filter needs monthly replacement, you’re overdue. We’ll inspect and give you an honest timeline.
Yes. Supply ducts push conditioned air to your rooms and tend to collect lighter dust that settles on horizontal runs in the basement. Return ducts pull air back and act as the primary debris trap, especially in Northglenn’s older homes where returns are often undersized and run at higher velocity. Cleaning only one side leaves half the debris in circulation. Our full system cleaning addresses both, plus the connecting plenum.
Yes, and in Northglenn this is critical. The plenum is the distribution box attached to your furnace, and in 1960s homes it’s often original fiberglass duct board. We inspect it with a camera, clean it gently if sound, or replace it if deteriorated. Excluding the plenum from a “full” cleaning misses the central junction where all your air mixes. We don’t call it full unless it is.
We do, selectively. Rotobrush is effective for galvanized metal ductwork and many residential applications, but we match the tool to the condition of your system. For fragile fiberglass duct board or deteriorated flex connectors common in Northglenn’s original housing, we use gentler HEPA-contained methods. The right tool for the right duct. We’ll show you what we’re using and why before we start.
