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 Westminster, CO
Whole-system HVAC cleaning in Westminster typically runs $380-$620 for a standard residential setup, with most jobs completed in a single visit. Westminster’s unique position between prairie dust corridors and foothill wildfire smoke paths, combined with aging 1980s-1990s fiberglass duct board, means duct systems here accumulate particulates faster than comparable metro areas. Call (720) 315-7291 for a written estimate before any work begins.
Why Westminster Homes Are Different
Westminster sits at a geographic pinch point few Colorado cities share. Upslope winds carry prairie dust from the eastern plains while wildfire smoke funnels down from the foothills to the west, loading duct systems with a double particulate source. The 2021 Marshall Fire corridor in neighboring Superior and Louisville sent demand waves through Westminster that still show up in our work - technicians in Standley Lake and Walnut Creek neighborhoods regularly pull gray-black fine ash from duct interiors years later, even from homeowners who kept windows closed during smoke events. Their HVAC return systems pulled smoke-laden air through leaky connections in unconditioned crawlspaces the entire time.
The housing stock compounds this. Westminster’s rapid build-out from roughly 1978-1998 produced ranch and two-story subdivisions fitted with fiberglass duct board rated for 25-30 years. That material is now visibly delaminating in many systems, releasing glass fibers into the air stream. Newer western developments near Standley Lake use complex flex-duct runs that develop sags and gaps at connections, trapping debris and bypassing filters. Semi-arid Front Range humidity regularly drops to 15-25%, increasing static charge inside ductwork and causing fine particulates to cling electrostatically to walls rather than reaching filters.
Our Main Westminster Services
Westminster homeowners contact us most often for these three services, each with its own dedicated page:
Air Duct Cleaning in Westminster
We clean the full duct network - supply runs, return trunks, and plenum - using negative-pressure extraction with Rotobrush and Nikro equipment. In Westminster, we pay particular attention to fiberglass duct board delamination in 1980s-1990s homes, where the camera often shows fiber shedding at elbows and joints. Every run is photographed before and after, and the written price is set before work starts. Air Duct Cleaning in Westminster
Dryer Vent Cleaning in Westminster
Dryer vent blockages in Westminster often contain compacted prairie dust mixed with lint, creating dense plugs that standard brushes struggle to clear. We use professional-grade augers and high-velocity air tools to remove these composite blockages, then verify airflow with a manometer. The job concludes with a documented photo of the clean vent interior. Dryer Vent Cleaning in Westminster
Duct Repair & Sealing in Westminster
Westminster’s aging flex-duct systems develop sags, gaps, and disconnected boots that bypass conditioned air into attics and crawlspaces. We repair or replace damaged sections and seal connections with mastic and metal-backed tape, then pressure-test the system to verify sealed performance. Duct Repair & Sealing in Westminster

BeforeAfterHVAC Cleaning in Westminster
Westminster’s combination of wildfire smoke residue, prairie dust, and delaminating fiberglass duct board puts unusual load on HVAC components. Evaporator coils in this market typically show a gray-black film that standard filter changes won’t address, and blower wheels accumulate dense, electrostatically charged debris. HVAC Cleaning here means addressing both the particulate sources unique to this location and the mechanical consequences of 30-40 year old duct systems still in service.
Evaporator Coil Cleaning
Signs you need it
Ice formation on the coil, reduced airflow at registers, or a musty odor when the AC cycles on in Westminster’s dry summers.
What it costs in Westminster
Evaporator coil cleaning in Westminster typically ranges $180-$340.
How we do it
We access the coil through the plenum, apply foaming cleaner approved for aluminum fins, rinse with low-pressure water, and photograph the coil before and after through a borescope.
Blower Cleaning
Signs you need it
Vibration or noise from the air handler, uneven airflow room-to-room, or dust puffing from registers when the system starts.
What it costs in Westminster
Blower cleaning in Westminster typically ranges $160-$280.
How we do it
We remove the blower assembly, clean the wheel and housing with compressed air and solvent, balance the assembly, and reinstall with a photographed before-and-after record.
What HVAC Cleaning Costs in Westminster
| Item | Typical range in Westminster |
|---|---|
| Evaporator coil cleaning | $180-$340 |
| Blower cleaning | $160-$280 |
| Full HVAC cleaning (coil + blower + air handler) | $380-$620 |
How do I know my HVAC needs cleaning, not just my ducts?
If your ducts are clean but rooms still heat unevenly, the blower wheel or evaporator coil is likely clogged - the camera will show which component is restricting airflow. Call (720) 315-7291 and we’ll inspect both the duct network and the mechanical components to pinpoint the restriction.
Can HVAC cleaning fix the musty smell when my AC turns on?
Yes - the odor usually comes from microbial growth on a wet evaporator coil or in the condensate pan, both addressed during coil cleaning with antimicrobial treatment and pan flushing. Call (720) 315-7291 for a written scope and price.
Air Quality & Sanitizing in Westminster
Westminster’s wildfire smoke exposure and aging fiberglass duct board create conditions where particulate load isn’t the only problem - biological growth and persistent odors follow. The same crawlspace leaks that pulled Marshall Fire smoke into duct systems also introduce moisture that supports mold in cooler months, while the 15-25% humidity swings stress any organic material in the airstream. Air Quality & Sanitizing here targets the specific contaminants our photo records show in Westminster homes.
Mold Treatment
Signs you need it
Visible growth on register grilles, a wet-cardboard odor when heat runs, or recent water intrusion in a crawlspace or basement.
What it costs in Westminster
Mold treatment in Westminster typically ranges $280-$480 per affected zone.
How we do it
We apply an EPA-registered antimicrobial through the duct system using a cold-fogger, treat the plenum and accessible trunk lines with contact spray, and provide lab-ready swab documentation if requested.
UV Light Installation
Signs you need it
Repeated mold recurrence after cleaning, or a household member with immunocompromise who needs continuous air-stream sterilization.
What it costs in Westminster
UV light installation in Westminster typically ranges $320-$580 including the lamp and power supply.
How we do it
We mount a Honeywell or Aprilaire UV-C lamp in the supply plenum, wire to the blower circuit for automatic operation, and verify irradiance at the coil surface with a meter.
What Air Quality & Sanitizing Costs in Westminster
| Item | Typical range in Westminster |
|---|---|
| Mold treatment (per zone) | $280-$480 |
| UV light installation | $320-$580 |
| Whole-system sanitizing (no mold) | $220-$380 |
Does UV light actually prevent mold in Westminster’s dry climate?
Yes - mold grows where there’s moisture, and Westminster’s crawlspaces and evaporator pans provide that even when outdoor humidity is low; UV-C at the coil surface stops growth before it colonizes. Call (720) 315-7291 for placement recommendations and a written price.
How do I know mold treatment worked?
We photograph every treated surface before and after, and Haven Standard Clause 5 requires that we show you the photo record before we leave; third-party post-treatment testing is available at your request. Call (720) 315-7291 to schedule.
