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 Highlands Ranch Homes Are Different
Highlands Ranch was mass-developed in rapid waves from the late 1980s through the mid-2000s, meaning the community now has an enormous, nearly uniform cohort of flex-duct HVAC systems hitting 20-35 years of age simultaneously, most never professionally cleaned. The semi-arid, high-altitude environment at roughly 5,900-6,200 feet suspends fine Front Range particulate dust and sends it recirculating through those aging corrugated flex ducts indefinitely. Homes backing up to the 70-plus miles of open-space trails experience measurably heavier pollen, soil dust, and weed-seed infiltration than interior lots, and technicians consistently pull visibly dirtier evaporator coils and return plenum debris from these properties. The production-built stock by Richmond American and Shea Homes used long duct runs serving two-story layouts with return-air chases built into framed walls that become significant debris collectors over decades.
Our Main Highlands Ranch Services
Homeowners in Highlands Ranch call us most often for deep duct cleaning and dryer vent maintenance, though duct repair work has risen sharply as the first wave of flex-duct systems passes 30 years.
Air Duct Cleaning in Highlands Ranch
We clean the full supply and return network using negative-pressure extraction, agitating debris from corrugated flex duct with Rotobrush contact systems before vacuum capture. In Highlands Ranch, we regularly find 2-4 inch debris build-up at first elbows in homes backing open space, and we document every run with before-and-after photos.

Dryer Vent Cleaning in Highlands Ranch
Dryer vent blockages in Highlands Ranch often combine lint with fine clay dust that hardens into dense obstructions in the long vent runs typical of two-story layouts. We pull the full obstruction, inspect with a camera, and measure airflow before and after. Dryer Vent Cleaning in Highlands Ranch
Duct Repair & Sealing in Highlands Ranch
Sagging flex duct, crimped runs, and disconnected boots are common in 20-35 year old Highlands Ranch systems. We repair or replace damaged sections and seal leaks with mastic, then pressure-test to verify. Duct Repair & Sealing in Highlands Ranch

BeforeAfterHVAC Cleaning in Highlands Ranch
Most Highlands Ranch HVAC systems have never had their evaporator coils or blower assemblies cleaned, despite running continuously in a climate where chinook winds drive fine dust through home envelopes year-round. The 2020 wildfire season deposited combustion particulates throughout Douglas County ductwork that standard filter changes cannot reach. HVAC Cleaning addresses the components that actually move and condition air, not just the ducts that carry it.
Evaporator Coil Cleaning
Signs you need it
Ice buildup on the coil, 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-$340.
How we do it
We access the coil through the plenum, apply foaming cleaner, rinse with low-pressure water, and photograph the full surface before and after.
Blower Cleaning
Signs you need it
Vibration or noise from the air handler, dust puffing from registers at startup, or uneven heating across zones.
What it costs in Highlands Ranch
Blower assembly cleaning in Highlands Ranch typically runs $140-$260.
How we do it
We remove the blower wheel, clean blades and housing with compressed air and solvent, balance the assembly, and reinstall with torque verification.
What HVAC Cleaning Costs in Highlands Ranch
| Item | Typical range in Highlands Ranch |
|---|---|
| Evaporator coil cleaning | $180-$340 |
| Blower assembly cleaning | $140-$260 |
| Full HVAC cleaning (coil + blower + housing) | $320-$580 |
How often should HVAC components be cleaned in Highlands Ranch?
Every 3-5 years for typical Highlands Ranch homes, or 2-3 years for properties backing open space or with pets. The 2020 wildfire particulate load accelerated buildup for many systems. Call (720) 315-7291 and we’ll inspect and quote in writing.
Can HVAC cleaning fix weak airflow upstairs?
It can if the restriction is a dirty coil or blower, but not if the issue is duct design or leakage. We diagnose before quoting, under Haven Standard Clause 1.
Air Quality & Sanitizing in Highlands Ranch
Highlands Ranch’s semi-arid climate keeps dust airborne rather than letting it settle, and the 20-35 year old flex-duct systems recirculate that load continuously through living spaces. Wildfire seasons have added fine combustion particulates to the mix, while homes near open-space corridors see elevated pollen and mold spore counts. Air Quality & Sanitizing targets biological and particulate contamination that mechanical cleaning alone cannot address.
Mold Treatment
Signs you need it
Musty odor at registers, visible growth on duct liner, or allergy symptoms that worsen when the system runs.
What it costs in Highlands Ranch
Mold treatment in Highlands Ranch typically runs $280-$520 depending on affected duct length.
How we do it
We apply EPA-registered fungistat to affected runs, mechanically remove visible growth, and verify with post-treatment inspection.
UV Light Installation
Signs you need it
Recurring mold despite cleaning, or a household with respiratory sensitivity to airborne biologicals.
What it costs in Highlands Ranch
UV light installation in Highlands Ranch typically runs $380-$650 including fixture and electrical connection.
How we do it
We mount a Honeywell or Aprilaire UV-C fixture in the supply plenum, wire to the blower circuit, and verify irradiance with a meter.
What Air Quality & Sanitizing Costs in Highlands Ranch
| Item | Typical range in Highlands Ranch |
|---|---|
| Mold treatment | $280-$520 |
| Bacteria sanitizing | $180-$340 |
| UV light installation | $380-$650 |
Does UV light actually work in dry climates like Highlands Ranch?
Yes, UV-C kills biological growth on coil and plenum surfaces regardless of ambient humidity; the target is the wet surfaces inside the air handler, not the air itself. We specify Honeywell and Aprilaire units with documented output. Call (720) 315-7291 for a written quote.
Is mold common in Highlands Ranch ducts?
Less common than in humid climates, but it occurs in homes with oversized AC units that short-cycle and fail to dehumidify, or where condensation collects in sagging flex duct.
