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
HVAC cleaning in Westminster typically runs $380-$620 for a whole-system job, with most homes in the 1975-1995 build era needing evaporator coil and blower attention alongside ductwork. Westminster’s Front Range position pulls fine prairie dust and wildfire particulate into aging fiberglass duct systems faster than calmer-climate metros, making documented cleaning essential. Call (720) 799-2292 and we’ll put a written price in your hand before any panel comes off.
Why Westminster Homes Are Different
Westminster’s residential core filled in heavily between 1975 and 1995, leaving thousands of homes with original fiberglass duct board or early flex-duct systems now 30-50 years old and typically never professionally cleaned. In older neighborhoods along the US-36 corridor and around 92nd Avenue, we regularly find return-air chases framed directly into wood-stud walls with drywall acting as the duct surface, no metal liner, decades of dust and drywall particulate packed into structural cavities.
The Front Range climate adds its own load. Westminster’s semi-arid conditions, roughly 14 inches of annual precipitation, keep humidity low but allow fine mineral dust and agricultural particulate from open Adams County land to infiltrate year-round. Chinook wind events accelerate this. The 2020 Cameron Peak and East Troublesome fires deposited measurable ash into HVAC systems across the northern metro, creating a documented cleaning need specific to this region. Newer master-planned communities like Bradburn and Legacy Ridge present construction-debris contamination in systems under 20 years old.
Our Main Westminster Services
Westminster homeowners call us most often for these three services, each with its own dedicated page:
Air Duct Cleaning in Westminster
We clean every duct run in Westminster homes with negative-pressure extraction, photographing the inside of each line before and after. Older fiberglass duct board plenums in the US-36 corridor require gentler agitation than modern sheet metal to avoid releasing glass fibers. Every job concludes with a Documented Photo Record delivered to you. Air Duct Cleaning in Westminster
Dryer Vent Cleaning in Westminster
Dryer vent blockages in Westminster’s lint-prone climate create genuine fire risk. We run a rotary brush through the full vent line to the exterior termination, measuring airflow before and after. The photo record shows what was actually removed. Dryer Vent Cleaning in Westminster
Duct Repair & Sealing in Westminster
Leaky ducts in Westminster’s aging systems waste conditioned air into attics and crawl spaces. We pressure-test the system, seal accessible joints with mastic, and photograph repairs. The 365-Day Done Right Promise covers our sealing work in writing. Duct Repair & Sealing in Westminster

BeforeAfterHVAC Cleaning in Westminster
Westminster’s 1975-1995 housing stock puts evaporator coils and blowers through decades of accumulated prairie dust and wildfire particulate without maintenance. The 2020 fire season alone loaded systems with fine ash that standard filters cannot capture. We approach HVAC Cleaning as a documented restoration, not a vacuum visit, with before-and-after photos of every component and a written price locked before work starts.
Evaporator Coil Cleaning
Signs you need it
Ice buildup on the coil, weak airflow from registers, or cooling that cannot keep up during Westminster’s summer heat waves.
What it costs in Westminster
Evaporator coil cleaning typically runs $180-$320 depending on access panel configuration and contamination level.
How we do it
We remove the access panel, apply foaming cleaner to the coil fins, rinse with low-pressure water, and photograph the coil surface before and after.
Blower Cleaning
Signs you need it
Vibration noise from the air handler, dust streaking from supply registers, or uneven heating across rooms in two-story Westminster tract homes.
What it costs in Westminster
Blower assembly cleaning typically runs $160-$280 for standard residential units.
How we do it
We remove the blower wheel and motor, clean each blade with compressed air and solvent, re-balance the assembly, and photograph the cleaned components.
What HVAC Cleaning Costs in Westminster
| Item | Typical range in Westminster |
|---|---|
| Evaporator coil cleaning | $180-$320 |
| Blower assembly cleaning | $160-$280 |
| Full HVAC system cleaning (coil + blower + air handler cabinet) | $380-$620 |
How do I know my HVAC system was actually cleaned?
Every component is photographed before and after, and the images are delivered with your job record. Haven Standard Clause 2 requires the photo record on every visit.
Why does my Westminster home need HVAC cleaning more often than my parents’ house in the Midwest?
Front Range dust, Chinook winds, and wildfire smoke load Westminster systems faster than humid-climate metros where precipitation settles particulate before it reaches your vents.
Air Quality & Sanitizing in Westminster
Westminster’s aging duct board and wildfire-ash loading create conditions where microbial growth and persistent odors take hold in HVAC systems. The same low humidity that keeps mold from spreading aggressively also allows spores to desiccate and remain airborne. We treat Air Quality & Sanitizing as a targeted intervention with specific chemistry and verification, not a scented fog.
Mold Treatment
Signs you need it
Musty airflow when the system first cycles on, visible spotting on fiberglass duct board, or allergy symptoms that worsen at home in Westminster’s dry winter heating season.
What it costs in Westminster
Whole-system mold treatment typically runs $450-$750 depending on contamination extent and duct access.
How we do it
We apply EPA-registered fungistat to affected duct runs, treat the evaporator coil and drain pan, and verify with post-treatment photography.
UV Light Installation
Signs you need it
Recurring mold after cleaning, or a Westminster home with chronic microbial issues in the air handler cabinet.
What it costs in Westminster
UV-C lamp installation in the air handler typically runs $280-$450 including the lamp and electrical connection.
How we do it
We mount a Honeywell or Aprilaire UV-C lamp in the supply plenum, wire to the blower circuit, and photograph the installation for your record.
What Air Quality & Sanitizing Costs in Westminster
| Item | Typical range in Westminster |
|---|---|
| Mold treatment (whole system) | $450-$750 |
| UV-C lamp installation | $280-$450 |
| Bacteria sanitizing (per system) | $220-$380 |
Does sanitizing leave chemicals in my air?
We use EPA-registered products rated for HVAC application, allow full dwell and dry time, and run the system on high before we leave to clear any residual.
Will UV light kill mold already in my ducts?
UV-C prevents new growth on irradiated surfaces but does not remove existing contamination, so we clean first, then install the lamp to maintain the result.

What Westminster Customers Say
"They found a disconnected duct in the crawl space that had been dumping conditioned air under the house for years. Photographed it, quoted the repair, fixed it."
- Devon A."The dryer vent was almost completely blocked with lint. They showed me the photograph and I understood immediately why the dryer had been running twice."
- Lucia M."Flat price agreed up front, no per-vent add-ons at the end. That was the whole reason I did not call the coupon company."
