We camera-inspect before we touch a thing, especially in homes where original fiberglass duct board plenums have been sitting untouched for five or six decades.

Why Bellows Air Duct & Vent Co. Is Northglenn’s Preferred HVAC Cleaning Company
Northglenn homeowners call us because we’ve been here long enough to know what “clean” actually means for their specific houses. A 1968 ranch off Huron Street isn’t a generic job. The original duct board plenum may be degrading. The flex-duct connectors in the full basement may be pulling apart. We check first, clean second, and show you the camera footage so you see what we saw.
Our technicians are uniformed, background-checked, and trained on the equipment we trust: Rotobrush rotary systems, Nikro HEPA vacuums, and Abatement Technologies containment gear. We don’t send day laborers or subcontractors. The person at your door works for Bellows, answers to our office, and carries our 90-Day Done Right Promise in writing.
Calls are answered by a live person, 24/7. Not an app. Not a callback queue. A real person who can book your Northglenn appointment, confirm your upfront price, and tell you when we’ll arrive. Most Northglenn jobs are completed in one visit. We stand behind it - no paperwork, no arguing.
Our HVAC Cleaning Services in Northglenn
Evaporator Coil Cleaning
Northglenn’s semi-arid climate and heavy seasonal cycling mean your evaporator coil works hard year-round. At 5,400 feet with low humidity and temperature swings that push your system from heating to cooling and back, the coil accumulates fine mineral dust and biological film that restricts airflow and drives up energy bills. In older Northglenn homes with original 1960s ductwork, compromised filters let more particulates reach the coil. We access the coil, apply foaming cleaner, rinse thoroughly, and treat with an antimicrobial solution to slow future buildup. A typical evaporator coil cleaning in Northglenn runs $180-$340.

Blower Cleaning
The blower motor and wheel are the engine of your airflow. In Northglenn’s original ranch homes, we’ve found blowers caked with debris that hasn’t been disturbed since the Johnson administration. A dirty blower strains the motor, reduces comfort, and recirculates dust through every room. We remove the blower assembly, clean the wheel and housing with compressed air and vacuum extraction, and reassemble with care. Blower cleaning in Northglenn typically costs $150-$280 as a standalone service, or less when bundled with full system cleaning.

Condenser Cleaning
Your outdoor condenser faces Northglenn’s high-plains winds directly. Cottonwood fluff from the South Platte corridor, agricultural dust from Adams County fields, and fine grit from chinook events clog the fins and reduce heat transfer. We wash the coils, straighten damaged fins, clear the base pan, and verify refrigerant pressures. Condenser cleaning in Northglenn generally runs $120-$220.

Air Handler Cleaning
The air handler is where your conditioned air begins its journey through those original trunk-and-branch ducts. We clean the cabinet, drain pan, and associated components, checking for standing water or microbial growth that can spread through the system. In Northglenn homes with full basements, we also inspect for gaps where high-wind infiltration reintroduces dust after cleaning. Air handler cleaning typically ranges $200-$380 depending on accessibility and condition.

Coil Treatment
After cleaning, we apply a specialized coil treatment that creates a protective barrier against dust adhesion and microbial growth. This isn’t a perfume mask. It’s a functional treatment that extends the interval between cleanings, which matters in Northglenn where external dust loads are higher than in sheltered mountain valleys. Coil treatment adds $60-$120 to a cleaning service and is included in our recommended full-system package for older homes.

Trusted Brands We Service in Northglenn
We clean and service equipment from every major manufacturer, and our trucks carry Rotobrush rotary cleaning systems and Nikro HEPA-filtered vacuums for containment. For coil treatments and sanitizing, we use Abatement Technologies products specified by serious HVAC contractors. We don’t show up with shop vacs and guesswork.

Parts and supplies are stocked locally, so if we find an issue during cleaning, we can often address it without ordering and rescheduling.
Common HVAC Cleaning Problems We See in Northglenn Homes
- Brittle fiberglass duct board plenums. The original plenums in Northglenn’s 1960s ranches become friable with age. Aggressive rotary brushing without prior camera inspection can fracture liner sections, releasing fiberglass particles directly into your air stream. We inspect first. Always.
- Deteriorating flex-duct connections in full basements. Those original trunk-and-branch systems rely on flex connectors that have dried, cracked, or pulled loose over 50+ years. Neglecting to seal these gaps means fine mineral dust from chinook winds recontaminates cleaned ducts within weeks.
- Heavy debris buildup on evaporator coils and blowers. Northglenn’s semi-arid climate, low humidity, and high wind events drive more particulates through aging filters and compromised ductwork. Skipping coil and blower cleaning on these 50-year-old systems accelerates the cycle of recirculation and buildup.
- Supply registers that have never been professionally cleaned. It’s common. The homeowner bought the house in 1987, changed the filter sometimes, and never thought about what accumulated behind the grille. We remove and clean every register as part of our standard service.

FAQs - HVAC Cleaning in Northglenn
Your Northglenn home was built during the city’s original master-planned development with original fiberglass duct board plenums and trunk-and-branch systems that are now 50-60 years old, far past any reasonable service interval, while newer Thornton construction uses sealed flex-duct or rigid metal systems with fewer infiltration points. Combined with Northglenn’s Adams County high-plains position where chinook and upslope wind events drive fine particulate dust into homes year-round, your aging infrastructure accumulates debris faster and from more compromised materials than modern construction. Call (844) 685-6342 for a camera inspection and exact quote - estimates are free.
Yes, we camera-inspect every furnace plenum before any rotary brushing begins, and this step is especially critical in Northglenn’s original 1960s ranches where fiberglass duct board has become brittle and friable with age. In the 80241 neighborhood off Washington St, we cleaned a 1968 ranch where the trunk-and-branch duct system had never been serviced. The fiberglass duct board plenum was degrading, so we used our Rotobrush with a HEPA vacuum and applied an antimicrobial coil treatment to the evaporator, restoring airflow and reducing dust infiltration from the high-plains winds. Call (844) 685-6342 for a free estimate.
Cleaning removes the source of the odor in most cases, but if your Northglenn home has original fiberglass duct board plenums that are degrading, the smell may return unless we also identify and address friable liner sections that continue to shed particles. We camera-inspect to distinguish between surface debris that cleaning removes and structural deterioration that requires repair or sealing. Our 90-Day Done Right Promise covers the follow-up if the issue persists. Call (844) 685-6342 to schedule.
For Northglenn’s 1960s-1970s homes with original ductwork and high-plains dust exposure, we recommend every 3-5 years for full system cleaning, with annual evaporator coil and blower inspection. Newer homes in less exposed positions may stretch to 5-7 years, but your original infrastructure and wind-driven particulate load shorten that interval. Our $89 Seasonal Tune-Up includes a condition assessment so you know where you stand without guessing. Call (844) 685-6342 to book.
Yes, but only with a modified protocol: camera inspection first, controlled brushing pressure, and HEPA containment throughout. Aggressive cleaning without identifying compromised sections can fracture the friable liner and release fiberglass into your air stream. We’ve developed this protocol specifically for Northglenn’s master-planned ranch stock, and we won’t proceed without the inspection step. Call (844) 685-6342 for a free estimate and we’ll walk you through exactly what your system needs.
