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 Centennial Homes Are Different
Centennial’s neighborhoods - Piney Creek, Foxridge, Willow Creek, Hunters Hill - were built almost entirely in planned tract phases between the late 1970s and mid-1990s. That means a concentrated wave of original ductwork is now 30-50 years old and overdue for service simultaneously, a dynamic you won’t find in newer suburbs where housing stock ages in staggered waves.
At 5,900-6,200 feet on the Front Range, Centennial’s arid air dries out flex duct seals and fiberglass duct liner faster than at lower elevations. Colorado’s chronically low relative humidity keeps ultra-fine High Plains prairie dust and wildfire smoke particulates airborne longer, allowing them to penetrate deeper into aging systems. In Foxridge and Piney Creek, many homes used internal fiberglass duct board rather than sheet metal; after 30-plus years in dry air, that liner crumbles and the HVAC system itself becomes the source of airborne glass fibers. Finished basements with drop ceilings conceal deteriorating ductwork homeowners have never inspected.
Our Main Centennial Services
Centennial homeowners call us most often for these three services:
Air Duct Cleaning in Centennial
We clean the full duct network - supply and return runs, trunk lines, and registers - using negative-pressure extraction (a vacuum system that pulls debris out while containing it) and rotary brush agitation. In Centennial’s 1975-1995 housing stock, we regularly find original galvanized sheet metal with corrosion at the seams, or fiberglass duct board shedding particulates into the airstream. Every run is photographed before and after. Air Duct Cleaning in Centennial includes the documented photo record as standard.
Dryer Vent Cleaning in Centennial
Dryer vent blockages are a leading cause of house fires, and Centennial’s lint accumulation is accelerated by the dry climate and frequent high-wind days that pressurize vent terminations. We clear the full run from appliance to exterior cap, measure airflow before and after, and photograph the obstruction. Dryer Vent Cleaning in Centennial takes 45-90 minutes for most homes.
Duct Repair & Sealing in Centennial
Seals fail faster at altitude. We repair disconnected runs, seal leaks with mastic or metal-backed tape (the proper materials, not duct tape), and replace degraded flex sections. In Willow Creek and Hunters Hill, we’ve found original duct tape turned to powder after 30 years in dry air. Duct Repair & Sealing in Centennial restores system efficiency and stops conditioned air from dumping into attics or crawl spaces.

BeforeAfterHVAC Cleaning in Centennial
Centennial’s forced-air gas furnace systems, installed during the 1975-1995 suburban boom, run hard through dramatic seasonal temperature swings at 6,000 feet. The combination of aged components, ultra-dry air degrading seals, and wildfire smoke particulates coating internal surfaces creates a maintenance backlog unique to this market. HVAC Cleaning addresses the components the ductwork connects to - the coil, blower, and air handler - where accumulated debris restricts airflow and strains equipment. We photograph every component before and after, and the written price is set before work begins under Haven Standard Clause 1.
Evaporator Coil Cleaning
Signs you need it
Weak airflow from registers, ice formation on the coil cabinet, or cooling bills that climb without thermostat changes.
What it costs in Centennial
Evaporator coil cleaning in Centennial typically runs $180-$340.
How we do it
We access the coil through the plenum (the distribution box above the furnace), apply foaming cleaner, rinse with low-pressure water, and photograph the fin condition before reassembly.
Blower Cleaning
Signs you need it
Rattling from the air handler cabinet, uneven heating across rooms, or a blower wheel visibly caked with dust when the panel is removed.
What it costs in Centennial
Blower cleaning in Centennial typically runs $140-$260.
How we do it
We remove the blower assembly, clean the wheel and housing with compressed air and solvent, balance the assembly, and photograph the cleaned components before reinstalling.
What HVAC Cleaning Costs in Centennial
| Item | Typical range in Centennial |
|---|---|
| Evaporator coil cleaning | $180-$340 |
| Blower cleaning | $140-$260 |
| Full HVAC cleaning (coil + blower + air handler) | $320-$580 |
How do I know my HVAC components need cleaning, not just my ducts?
If your registers blow weakly despite clean ducts, or your system short-cycles in summer, the coil or blower is likely restricted. We inspect these components during every duct cleaning and photograph what we find - no separate visit required. Call (719) 259-4520 to schedule.
Will cleaning my HVAC components improve efficiency in Centennial’s climate?
Yes - a clean coil transfers heat properly, and a clean blower moves design airflow. In Centennial’s dry, high-altitude conditions, where systems already work harder to overcome thin air, removing debris reduces runtime and wear. We document the before-and-after amp draw on the blower motor when accessible.
Air Quality & Sanitizing in Centennial
Centennial’s 30-50-year-old duct systems, combined with wildfire smoke events that push fine combustion particulates through air intakes, create conditions where biological growth and persistent odors take hold in ways newer systems resist. The same dry air that degrades fiberglass liner also allows ultra-fine particulates to settle deep in duct runs, providing a substrate for mold and bacteria when humidity spikes seasonally. Air Quality & Sanitizing treats these problems at the source with documented application methods and post-treatment verification photos.
Mold Treatment
Signs you need it
Musty odor when the system cycles, visible growth on register faces, or aggravated allergies that worsen when home.
What it costs in Centennial
Mold treatment in Centennial typically runs $280-$520.
How we do it
We apply an EPA-registered antimicrobial through the duct system using a fogging device, treat affected registers and the plenum directly, and photograph all treated surfaces for the job record.
UV Light Installation
Signs you need it
Recurring mold or biofilm on the evaporator coil, or a household with allergy-sensitive occupants and chronic HVAC-related symptoms.
What it costs in Centennial
UV light installation in Centennial typically runs $380-$680.
How we do it
We mount a UV-C lamp in the supply plenum or above the coil, wire it to the blower circuit for automatic operation, and photograph the installed position for the job record.
What Air Quality & Sanitizing Costs in Centennial
| Item | Typical range in Centennial |
|---|---|
| Mold treatment | $280-$520 |
| UV light installation | $380-$680 |
| Full air quality package (treatment + UV) | $480-$920 |
Does wildfire smoke make air quality treatment more necessary in Centennial?
Yes - fine combustion particulates from regional wildfires penetrate standard filtration and settle in duct runs, where they combine with dust to support microbial growth when humidity rises. We treat these accumulations with antimicrobial application and can recommend filtration upgrades. Call (719) 259-4520 for an assessment.
How do I verify the mold treatment was actually applied?
We photograph every treated surface before and after application, include these images in your documented photo record, and note the product lot number and application time on the written scope. Haven Standard Clause 2 requires this documentation on every sanitizing job.

"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."
- Suzanne B."My allergies genuinely improved. They also told me the ducts did not need sealing, which I had been quoted for elsewhere."
- Petra K.
