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.
Air Duct Cleaning in Stonegate, CO
Most Stonegate homes run original flex-duct systems installed during the 1990s-early 2000s Douglas County build-out, now 25-30 years old and hitting the same failure thresholds at the same time. HVAC cleaning here means addressing decades of compacted debris at low points, dried mastic at plenum connections, and wildfire smoke particulate pushed through the system by Front Range winds. We dispatch crews from our Denver office to Stonegate daily; call (720) 513-5159 for a written estimate before any work begins.
Why Stonegate Homes Are Different
Stonegate sits near the Palmer Divide at roughly 5,900-6,000 feet, where high-velocity Front Range winds drive semi-arid prairie dust and wildfire smoke particulate deep into duct systems. The elevation also means 40-50°F single-day temperature swings and winter humidity low enough to crack joint seals faster than in coastal climates.
The housing stock is remarkably uniform: production builders used a limited set of floor plans with flexible duct runs that now sag between joists and shed deteriorating liner material. Our crews have learned that specific models almost always have an undersized return-air trunk in the same location, creating a choke point that loads disproportionate dust and accounts for many air quality complaints after 20-plus years. This predictability lets us diagnose faster, but it also means the problems are systemic across the community.
Our Main Stonegate Services
Stonegate homeowners call us most often for these three services, each with its own dedicated page and pricing.
Air Duct Cleaning in Stonegate
We clean every duct run with negative-pressure extraction, photograph the interior before and after, and deliver the photo record as part of the standard job file. The flex-duct systems common in Stonegate require careful handling to avoid tearing aged liners. Air Duct Cleaning in Stonegate covers full-system pricing and what the photo documentation includes.

Dryer Vent Cleaning in Stonegate
Lint accumulation in dryer vents is accelerated by Stonegate’s windy, dry climate, and the two-story layouts here create longer vent runs that clog faster. We clean the full run from appliance to termination, check airflow with a manometer, and document the before-and-after. Dryer Vent Cleaning in Stonegate has full details.

Duct Repair & Sealing in Stonegate
Aged mastic tape at plenum connections and sagging flex-duct low points are the two failures we see most. We repair or replace damaged sections, seal joints with proper materials rated for Colorado’s temperature swings, and pressure-test the system. Duct Repair & Sealing in Stonegate explains the process and costs.

Before
AfterHVAC Cleaning in Stonegate

Stonegate’s 25-30-year-old HVAC systems need component-level cleaning, not just duct vacuuming. The same wildfire smoke particulate and prairie dust that foul ductwork also coat evaporator coils and blower assemblies, reducing efficiency and circulating debris back into cleaned ducts. HVAC Cleaning covers the full scope of what we address.
Evaporator Coil Cleaning
Signs you need it
Ice buildup on the coil, weak airflow from registers, or a musty smell when the AC cycles on in July.
What it costs in Stonegate
Evaporator coil cleaning typically runs $280-$420, depending on accessibility and contamination level.
How we do it
We remove the coil if accessible, apply foaming cleaner, rinse with low-pressure water, and photograph the fin condition before reassembly.
Blower Cleaning
Signs you need it
Dust puffing from registers at startup, uneven heating between floors, or a motor that labors louder than in prior seasons.
What it costs in Stonegate
Blower assembly cleaning typically runs $240-$380, with squirrel-cage removal adding labor on tighter units.
How we do it
We pull the blower housing, clean the squirrel cage and motor housing with compressed air and solvent, balance the assembly, and test amp draw before reinstalling.
What HVAC Cleaning Costs in Stonegate
| Item | Typical range in Stonegate |
|---|---|
| Evaporator coil cleaning | $280-$420 |
| Blower assembly cleaning | $240-$380 |
| Full HVAC cleaning (coil + blower + air handler) | $520-$780 |
How do I know my HVAC components need cleaning, not just my ducts?
If you still smell dust or see reduced airflow after duct cleaning, the coil or blower is likely recontaminating the air stream. We inspect both with a borescope during every estimate and show you the photo before quoting.
Will cleaning my evaporator coil help with wildfire smoke smell?
Yes, if the coil has trapped particulate from past smoke events, but persistent smoke odor usually requires additional sanitizing. We test and quote both if needed.
Air Quality & Sanitizing in Stonegate

Stonegate’s tight, energy-efficient production homes trap wildfire smoke particulate and microbial growth from condensation in aging flex-duct low points. Air quality work here addresses what duct cleaning leaves behind: biological contamination and fine particulate that standard vacuuming cannot remove. Air Quality & Sanitizing details the full protocol.
Mold Treatment
Signs you need it
Visible growth on duct liner, a persistent earthy smell after the system runs, or allergy symptoms that worsen at home in Stonegate’s humid summer weeks.
What it costs in Stonegate
Spot mold treatment runs $340-$560; full-system application with fogging runs $680-$1,100 for typical Stonegate homes.
How we do it
We apply an EPA-registered fungistat to affected runs, fog the full system with a mechanical mister, and collect post-treatment swabs for the photo record.
UV Light Installation
Signs you need it
Repeated microbial growth after cleaning, or a household member with respiratory sensitivity to Colorado’s worsening smoke seasons.
What it costs in Stonegate
Single-lamp UV installation runs $480-$720, including electrical connection and mounting at the evaporator or return plenum.
How we do it
We mount a Honeywell or Guardsman UV-C lamp at the coil or return, wire to the blower circuit, and show you the lamp operation before closing the panel.
What Air Quality & Sanitizing Costs in Stonegate
| Item | Typical range in Stonegate |
|---|---|
| Spot mold treatment | $340-$560 |
| Full-system sanitizing with fogging | $680-$1,100 |
| UV-C lamp installation | $480-$720 |
Does UV light actually work in Stonegate’s dry climate?
UV-C works on microbial growth at the coil and drain pan, where moisture concentrates; it does not remove dust or smoke particulate, so we pair it with filtration upgrades when smoke is the primary concern.
How do I know mold treatment was actually done?
We photograph every treated run before and after, include application timestamps, and deliver the photo record with your written invoice under Haven Standard Clause 1.
