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 Highlands Ranch, CO

Call (720) 513-5159 for a written estimate before any work starts.
Why Highlands Ranch Homes Are Different
Highlands Ranch sits at roughly 5,800-6,000 feet in a semi-arid climate where fine particulates stay suspended longer than at lower elevations, so HVAC systems cycle dust continuously. The housing stock is remarkably uniform: almost entirely 2-story single-family homes built between the late 1980s and mid-2000s by Richmond American, Shea Homes, and similar production builders, with near-universal finished basements that add significant hidden ductwork behind drywall and through framed walls.
In Northridge and Westridge, the early-to-mid 1990s builds are now 30+ years old. The foil-and-plastic connections between flex duct sections and rigid trunk lines commonly separate or sag. When our camera enters those runs, we regularly find gaps that have been recirculating conditioned air into wall cavities for years. Front Range wildfire smoke since 2020 has pushed fine combustion particles directly into these systems, accelerating buildup in homes that often have never had a single duct cleaning since move-in.
Our Main Highlands Ranch Services
Most Highlands Ranch homeowners who call us start with one of these three services:
Air Duct Cleaning in Highlands Ranch
We clean the full supply and return network in Highlands Ranch homes, including the extended basement runs behind finished ceilings that production builders here tucked out of sight. Every job includes a Documented Photo Record of each duct run, before and after, delivered as part of your standard job record. Air Duct Cleaning in Highlands Ranch.
Dryer Vent Cleaning in Highlands Ranch
Dryer vent cleaning in Highlands Ranch addresses the full exhaust path from appliance to exterior termination, critical in these 2-story homes where long vertical runs are common. Lint accumulation at altitude dries faster but compacts denser, restricting airflow and extending dry times. Dryer Vent Cleaning in Highlands Ranch.
Duct Repair & Sealing in Highlands Ranch
Duct repair in Highlands Ranch often follows cleaning, especially in Northridge and Westridge where aged flex connections separate behind basement drywall. We photograph every gap, quote repair in writing before opening walls, and deliver before-and-after documentation. Duct Repair & Sealing in Highlands Ranch.

BeforeAfterHVAC Cleaning in Highlands Ranch
HVAC cleaning in Highlands Ranch targets the components that move and condition air - coils, blowers, condensers, and heat exchangers - in systems that have run 25-35 years without service in many original-owner homes. The semi-arid climate and high altitude keep particulates airborne longer, so these components load faster than in humid or low-elevation markets. We document every stage with photographs and deliver a written scope before touching a single panel, under Haven Standard Clause 1. HVAC Cleaning is our most called-for service in this market.
Evaporator Coil Cleaning
Signs you need it
Ice buildup on refrigerant lines, weak airflow from registers, or cooling that cannot keep up on 90-degree Front Range afternoons.
What it costs in Highlands Ranch
Evaporator coil cleaning in Highlands Ranch typically runs $180-$320.
How we do it
We access the coil through the plenum (the main air distribution box), apply foaming cleaner, rinse with low-pressure water, and photograph the fin surface before and after.
Blower Cleaning
Signs you need it
Vibration noise from the air handler, uneven airflow room to room, or dust puffing from registers when the system cycles on.
What it costs in Highlands Ranch
Blower cleaning in Highlands Ranch typically runs $150-$280.
How we do it
We remove the blower assembly, clean the squirrel cage and motor housing with compressed air and solvent, balance the wheel, and photograph the assembly before reinstallation.
What HVAC Cleaning Costs in Highlands Ranch
| Item | Typical range in Highlands Ranch |
|---|---|
| Evaporator coil cleaning | $180-$320 |
| Blower cleaning | $150-$280 |
| Full HVAC system cleaning (coil + blower + condenser) | $350-$650 |
How do I know my HVAC components actually need cleaning?
We photograph every component before quoting work; if the coil fins are clean and the blower wheel shows minimal dust, we say so and charge nothing for the inspection. Call (720) 513-5159 for a free estimate.
Can HVAC cleaning improve my energy bills in Highlands Ranch?
Yes - a dirty evaporator coil or blower wheel restricts airflow and forces longer run times, which at altitude already stresses systems; cleaning restores design airflow and can reduce cycle length. Call (720) 513-5159 for a free estimate.
Air Quality & Sanitizing in Highlands Ranch
Air quality and sanitizing in Highlands Ranch addresses what cleaning leaves behind: microbial growth in damp plenum corners, bacteria on coil surfaces, and persistent smoke odor from Front Range wildfire events that standard particulate removal cannot touch. The same low humidity that keeps dust airborne also dries mucous membranes, so Highlands Ranch residents often notice air quality problems faster than in humid climates. We treat the source, not the symptom, with documented before-and-after verification. Air Quality & Sanitizing.
Mold Treatment
Signs you need it
Musty odor when the system cycles, visible growth on register boots, or recent water intrusion in basement duct runs.
What it costs in Highlands Ranch
Mold treatment in Highlands Ranch typically runs $250-$450 per affected zone.
How we do it
We apply EPA-registered antimicrobial through the duct network, fog the plenum with Abatement Technologies equipment, and photograph treated surfaces for verification.
UV Light Installation
Signs you need it
Recurring microbial growth after cleaning, allergy symptoms that persist year-round, or a home with chronic humidity control issues in the basement.
What it costs in Highlands Ranch
UV light installation in Highlands Ranch typically runs $300-$550 including hardware and labor.
How we do it
We mount a UV-C lamp in the supply plenum upstream of the coil, wire to the air handler’s 24-volt circuit, and photograph placement and electrical connection.
What Air Quality & Sanitizing Costs in Highlands Ranch
| Item | Typical range in Highlands Ranch |
|---|---|
| Mold treatment (per zone) | $250-$450 |
| UV light installation | $300-$550 |
| Whole-home air quality package (treatment + UV) | $450-$850 |
Does UV light actually kill mold in ducts?
UV-C light at 254 nanometers damages mold DNA and prevents reproduction when installed with adequate dwell time and line-of-sight to the coil surface; it does not remove dead material, so we still clean first. Call (720) 513-5159 for a free estimate.
Is mold treatment safe for kids and pets?
We use EPA-registered products with published re-entry times, typically 2-4 hours with the system running; we document the product name and re-entry time in writing before application. Call (720) 513-5159 for a free estimate.
