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.

Why Castle Rock Homes Are Different
Castle Rock sits at 6,224 feet on the Palmer Divide, a high ridge that pulls stronger, more erratic winds across the city than anything the Denver metro sees 30 miles north. Those winds drive fine dust through return air pathways year-round, and during wildfire season, smoke from the Pike National Forest and Douglas County open lands funnels directly into tightly sealed modern HVAC systems.
The housing stock compounds this. Master-planned communities like The Meadows, Crystal Valley Ranch, Terrain, and Plum Creek were built from the late 1990s through today, overwhelmingly large single-family homes with multi-zone forced-air, finished basements, and extended duct runs. Many have never been cleaned since the builder handed over keys. Technicians in eastern Terrain and Cobblestone Ranch regularly pull bright-white drywall compound dust and foam sealant scraps from main supply trunks, evidence the system was installed in open construction and untouched since.

Before
AfterHVAC Cleaning in Castle Rock

HVAC cleaning in Castle Rock addresses a specific dual problem: post-construction debris still sitting in systems that have never been serviced, plus seasonal wildfire smoke and wind-driven dust that loads coils and blowers faster than at lower elevations. We use Rotobrush and Nikro equipment for negative-pressure extraction through the full air-handling assembly. HVAC Cleaning covers our full methodology for every component.
Evaporator Coil Cleaning
Signs you need it
Ice on the coil, weak airflow from registers, or a musty smell when the AC first cycles on in spring.
What it costs in Castle Rock
Evaporator coil cleaning in Castle Rock typically runs $180-$340.
How we do it
We access the coil through the plenum, apply foaming cleaner, rinse with low-pressure water, and photograph the fin condition before and after.
Blower Cleaning
Signs you need it
Vibration noise from the air handler, uneven heating across zones, or dust puffing from registers at startup.
What it costs in Castle Rock
Blower assembly cleaning in Castle Rock typically runs $140-$280.
How we do it
We remove the blower housing, clean the wheel and motor housing with compressed air and solvent, balance the assembly, and document runout with a photo.
What HVAC Cleaning Costs in Castle Rock
| Item | Typical range in Castle Rock |
|---|---|
| Evaporator coil cleaning | $180-$340 |
| Blower assembly cleaning | $140-$280 |
| Full system HVAC cleaning (coil, blower, plenum) | $380-$620 |
How often should HVAC cleaning happen in Castle Rock?
Every 3-5 years for most Castle Rock homes, sooner if you’ve never had a post-construction cleaning or after heavy wildfire smoke seasons. Call (719) 259-4520 and we’ll assess your system with a camera.
Will HVAC cleaning fix uneven temperatures between floors?
It helps if the problem is restricted airflow from dirty coils or blowers, but persistent zoning issues may need duct sealing or balancing. We diagnose before quoting.
Air Quality & Sanitizing in Castle Rock

Castle Rock’s combination of new-construction debris, wildfire smoke infiltration, and tight modern building envelopes creates conditions where microbial growth and persistent odors take hold in ductwork and air handlers. We treat these with documented application protocols and verifiable equipment. Air Quality & Sanitizing details our full approach.
Mold Treatment
Signs you need it
Visible growth on register fins, a wet-cardboard smell when the system runs, or allergy symptoms that spike at home.
What it costs in Castle Rock
Mold treatment in Castle Rock typically runs $280-$520 depending on affected duct length.
How we do it
We apply EPA-registered antimicrobial through the full duct system under negative pressure, fog the air handler, and deliver lab-ready swab results if requested.
UV Light Installation
Signs you need it
Recurring microbial growth after cleaning, or a home with high occupancy and limited fresh-air ventilation.
What it costs in Castle Rock
UV light installation in Castle Rock typically runs $320-$580 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 show you the installation with a before photo of the empty plenum.
What Air Quality & Sanitizing Costs in Castle Rock
| Item | Typical range in Castle Rock |
|---|---|
| Mold treatment (duct system) | $280-$520 |
| UV light installation | $320-$580 |
| Bacteria sanitizing (whole system) | $220-$380 |
Is UV light worth it in Castle Rock’s dry climate?
Yes, because Castle Rock’s tight modern homes limit fresh air exchange, and wildfire smoke seasons create organic loading that UV-C prevents from colonizing the coil. Call (719) 259-4520 for a written assessment.
How do I know mold treatment actually worked?
We photograph every treated surface before and after, and we can collect swab samples for independent lab analysis at your request.
