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
HVAC cleaning in Northglenn typically runs $340-$620 for a complete system, and every job starts with a written price before any panel comes off. Northglenn’s 1960s-1970s ranch homes were built with original sheet-metal ductwork that is now 50-60 years old, and Colorado’s Front Range thermal inversion traps fine particulates against the foothills year-round. That combination means Northglenn homeowners see elevated debris loads and degraded fiberglass duct liner that newer suburbs simply don’t match. Call (720) 513-5159 for a free estimate.
Why Northglenn Homes Are Different
Northglenn was built almost entirely between 1959 and 1975 as one of Colorado’s first master-planned communities. The vast majority of its ranch-style homes share a nearly identical cohort of 50-60-year-old duct systems aging in lockstep. That uniform vintage, compounded by Colorado’s Front Range thermal inversion trapping fine particulates and increasingly severe wildfire smoke seasons, creates a city-wide duct contamination problem that is both age-specific and pervasive.
At roughly 5,400 feet, Northglenn’s semi-arid climate keeps fine dust particles suspended rather than settled, dramatically increasing the particulate load drawn through residential HVAC systems. The thermal inversion layer traps vehicle exhaust and fine particulates against the foothills, meaning Northglenn homes recirculate elevated concentrations of ambient pollution year-round. Wildfire smoke events add acute spikes in smoke particle infiltration. Many homes also have ductwork routed through unconditioned crawl spaces, where seasonal moisture fluctuations introduce debris and biological growth.
Because the original ranch homes were developed by the same handful of builders in a compressed 15-year window, technicians routinely encounter the same failure city-wide: fiberglass duct liner from the 1960s-70s that has begun shedding fibers directly into the airstream. Smoke particulates adhere to the already-compromised liner surface and recirculate through the home.
Our Main Northglenn Services
Northglenn homeowners most often call us about these three services.
Air Duct Cleaning in Northglenn
We clean the full duct network, from the plenum (the main distribution box) through every duct run to each register, using negative-pressure extraction to pull debris out rather than push it deeper. In Northglenn, we regularly find the original fiberglass liner degraded to the point of shedding fibers, especially in homes near construction zones where soil disturbance adds to the load. Every job ends with a Documented Photo Record of every run. Air Duct Cleaning in Northglenn is quoted with a written price before work starts.
Dryer Vent Cleaning in Northglenn
Dryer vent cleaning removes lint accumulation from the transition duct, the wall run, and the exterior termination hood. Northglenn’s older ranch homes often have longer vent runs through unconditioned crawl spaces or attics, where temperature swings create condensation that packs lint into dense blockages. We photograph the full length before and after. Dryer Vent Cleaning in Northglenn carries a written upfront price and the 365-Day Done Right Promise.
Duct Repair & Sealing in Northglenn
Duct repair addresses disconnected runs, corroded sheet metal, and degraded liner; sealing closes the gaps that leak conditioned air into crawl spaces and attics. Northglenn’s original tract-built homes often show identical failure patterns at the plenum connections and flex-duct transitions. We document every repair with before-and-after photos and provide a written scope. Duct Repair & Sealing in Northglenn is quoted in writing before any work begins.

BeforeAfterHVAC Cleaning in Northglenn
HVAC cleaning in Northglenn addresses the entire forced-air system, not just the ducts. The city’s 1960s-1970s ranch homes run their heating and cooling through equipment that has cycled Front Range dust, wildfire particulates, and degraded fiberglass fibers for decades. HVAC Cleaning from CleanRun includes the evaporator coil, blower assembly, condenser, and air handler, with a written price before work starts and a Documented Photo Record delivered after.
Evaporator Coil Cleaning
Signs you need it
Ice buildup on the coil, reduced airflow from registers, or the system running longer to reach temperature.
What it costs in Northglenn
Evaporator coil cleaning in Northglenn typically ranges from $180 to $340.
How we do it
We access the coil through the plenum, apply foaming cleaner, rinse with low-pressure water, and photograph the fins before and after.
Blower Cleaning
Signs you need it
Vibration or noise from the air handler, uneven airflow between rooms, or dust streaking near the return grille.
What it costs in Northglenn
Blower cleaning in Northglenn typically ranges from $140 to $260.
How we do it
We remove the blower assembly, clean the wheel and housing with compressed air and solvent, balance the rotation, and document with photos.
What HVAC Cleaning Costs in Northglenn
| Item | Typical range in Northglenn |
|---|---|
| Complete HVAC system cleaning | $340-$620 |
| Evaporator coil cleaning | $180-$340 |
| Blower cleaning | $140-$260 |
How do I know my HVAC system needs cleaning, not just the ducts?
If your ducts are clean but rooms still heat unevenly, the blower wheel or evaporator coil is likely clogged with debris. We inspect both during every HVAC cleaning in Northglenn and show you the photo evidence. Call (720) 513-5159 for a free estimate.
Can HVAC cleaning fix the musty smell when my AC runs?
Musty odors usually come from biological growth on the evaporator coil or in the condensate pan. Cleaning the coil and treating the pan typically resolves it; we photograph the condition before and after. Call (720) 513-5159 for a written quote.
Air Quality & Sanitizing in Northglenn
Air quality and sanitizing in Northglenn targets the particulate and biological load that the city’s aging duct systems cannot filter out. The 1960s-1970s ranch homes’ original fiberglass liner sheds fibers into the airstream, and wildfire smoke particulates adhere to those degraded surfaces, recirculating through living spaces. Air Quality & Sanitizing from CleanRun includes treatment with professional-grade equipment and a written price before any work begins.
Mold Treatment
Signs you need it
Visible growth on registers or inside duct runs, a persistent earthy odor, or occupants with worsening allergy symptoms.
What it costs in Northglenn
Mold treatment in Northglenn typically ranges from $280 to $520.
How we do it
We apply EPA-registered antimicrobial through the duct system using a fogging device, treat the plenum and each run, and provide before-and-after photos.
UV Light Installation
Signs you need it
Recurring biological growth after cleaning, frequent HVAC filter clogging, or occupants with respiratory sensitivities.
What it costs in Northglenn
UV light installation in Northglenn typically ranges from $340 to $580.
How we do it
We mount a UV-C lamp in the supply plenum, wire it to the blower circuit, and verify irradiance levels with a meter.
What Air Quality & Sanitizing Costs in Northglenn
| Item | Typical range in Northglenn |
|---|---|
| Mold treatment | $280-$520 |
| UV light installation | $340-$580 |
| Bacteria sanitizing | $220-$420 |
Does sanitizing remove wildfire smoke particles from my ducts?
Sanitizing kills biological contaminants; smoke particles require physical removal through duct cleaning first. We often pair both services in Northglenn after heavy smoke events. Call (720) 513-5159 for a written scope and price.
How long does mold treatment take?
Most residential mold treatments in Northglenn take 3-4 hours, including application time and drying period. We deliver the photo record the same day. Call (720) 513-5159 to schedule.
