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.
Abatement Technologies Coil Cleaning: The Aurora Owner’s Guide
CleanRun Air Duct Cleaning Aurora stocks and installs Abatement Technologies-compatible coil cleaning assemblies for residential and light-commercial HVAC systems, with typical installed pricing between $340 and $680 depending on coil accessibility and contamination level. Most Aurora homeowners who call us about this service have already noticed their energy bills climbing or their system running longer cycles than it used to. We carry the right foaming agents, low-pressure rinse equipment, and protective pan liners for Abatement Technologies AHU and HEPA-Care series units on every truck, and we can usually schedule within 48 hours.
Most owners figure out something’s wrong with their coil when the upstairs never quite cools off in July, or when they spot ice forming on the refrigerant lines outside. The coil sits inside the air handler, usually above the furnace or in a dedicated closet, and it’s the surface where heat actually leaves your air. When it’s clogged with pollen, pet dander, and the fine dust that blows through Aurora’s dry winters, the system works harder for less result. We show you the photo first, then we talk about what comes next.
Which Abatement Technologies Models This Applies To
Abatement Technologies builds two main product families where coil cleaning comes up: the HEPA-Care portable and ceiling-mounted air filtration units, and the AHU-series air handling units used in remediation and high-end residential installs. The HEPA-Care HC500, HC800, and HC1500 models use a compact evaporator coil behind the first filter bank; the AHU-800, AHU-1200, and AHU-2000 series use larger cased coils with drain pans that need proper sloping and liner protection during cleaning.
To identify your unit, check the nameplate on the side of the housing. It lists model number, serial prefix, and rated CFM. The critical spec for us is coil fin density, measured in fins per inch. Abatement Technologies typically uses 8 to 14 FPI depending on the series; higher density traps more debris but also requires lower-pressure rinse equipment to avoid bending the aluminum. We match our cleaning approach to that spec.
CleanRun Air Duct Cleaning Aurora is an independent service provider, not affiliated with Abatement Technologies. We use manufacturer-recommended foaming agents where available, but we also stock quality aftermarket equivalents that meet the same pH-neutral, non-corrosive standards. For units still under warranty, we note whether OEM chemicals are required to preserve coverage. Most Aurora homeowners with units past the five-year mark choose the aftermarket route; the cleaning result is identical, and the price drops accordingly.
Signs Your Abatement Technologies Coil Cleaning Is Failing

- Longer cooling cycles with less temperature drop. The thermostat calls for cooling, the compressor runs, but the supply air at your registers only drops 8 to 12 degrees instead of the normal 18 to 22. The coil’s surface area is choked with debris, so heat transfer collapses even though refrigerant pressures look normal.
- Ice formation on refrigerant lines or the coil itself. A dirty coil restricts airflow across the fins, which drops the surface temperature below freezing. Moisture in the air flash-freezes instead of draining. In Aurora’s low-humidity climate, this usually shows up as a thin frost line rather than a solid block, but the damage to the compressor is the same.
- Musty or sour smell when the blower kicks on. Organic debris on the coil, combined with condensate in the drain pan, grows microbial film. Abatement Technologies units with UV options delay this, but no UV system eliminates the need for physical cleaning. The smell is your first warning before visible contamination spreads.
- Water stains below the air handler or in the ceiling. A clogged coil often means a clogged drain pan. When condensate can’t flow to the trap fast enough, it overflows. In ranch homes near the Aurora Hills Golf Course, we’ve found pans rusted through after years of slow overflow that the owner never traced back to the coil.
- Energy bills rising 15 to 30 percent with no rate change. The system compensates for poor heat transfer by running longer. Xcel Energy bills in Aurora spike hardest in July and August when the coil is already at its dirtiest and the outdoor condenser is fighting 90-degree days.

AfterReplacement Cost & What’s Included
Coil cleaning for Abatement Technologies systems in Aurora runs $340 to $680 installed, with the full job documented under Haven Standard Clause 1: written price before any work starts. The low end covers accessible HEPA-Care units with light contamination, single-stage foaming, and rinse. The high end applies to AHU-series units in tight mechanical closets, heavy buildup requiring multiple chemical passes, and drain pan restoration.
Here’s how the pricing breaks:
| Service Component | Typical Range |
|---|---|
| Standard coil cleaning (accessible, light to moderate debris) | $340 - $450 |
| Heavy-contamination restoration (multiple passes, pan cleaning) | $480 - $580 |
| Restricted-access surcharge (attic, crawlspace, tight closet) | $80 - $120 |
| Drain pan treatment and algae inhibitor | $45 - $65 |
Every price is written and signed before we touch the unit. The work includes full system inspection, before-and-after photography of the coil surface and drain pan, and a 365-Day Done Right Promise backed in writing. If contamination returns because our cleaning was incomplete, we return and correct it at no charge. We also stock Lennox, Trane, and Carrier coil cleaning components for mixed-system homes.
DIY or Call Us?

There’s a short list of things an Aurora homeowner can safely check before calling. Verify your filter is clean and correctly seated. Confirm the thermostat is set to cooling and the outdoor unit’s running. Look at the condensate drain line outside; if it’s bone-dry in summer while the AC runs, you likely have a clog upstream.
What we don’t recommend: opening the air handler cabinet, spraying foaming cleaner from a hardware store, or using a pressure washer on the fins. Abatement Technologies coils use aluminum fins bonded to copper tubes; bend the fins and you’ve permanently reduced airflow. Use the wrong chemical and you corrode the tubing. Worse, the electrical compartment sits inches from the coil in most AHU-series units; wet hands and 240 volts are a bad combination. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and they lock out power before the cabinet opens.
If you’ve checked the basics and the symptoms persist, call (720) 513-5159. We’ll give you a free second opinion on any written estimate you’ve already received, and we’ll put our own flat price next to it.
FAQs
In Aurora’s climate, with standard 1-inch pleated filters changed every 60 to 90 days, a thorough coil cleaning lasts three to five years. Homes near construction zones or with multiple pets may see faster recontamination. We timestamp your photo record so you have a baseline for comparison.
No. Once debris is embedded in the fin pack, physical removal is the only fix. Chemical cleaning is that removal process; there’s no separate “repair” option that avoids it. If the coil itself is leaking refrigerant, that’s a replacement job, not a cleaning, and we’ll tell you immediately upon inspection. Call (720) 513-5159 for an exact quote; estimates are free.
Most Abatement Technologies coil cleanings take 90 minutes to two and a half hours from arrival to final test. HEPA-Care units in open basements run shorter; AHU-series units in attic installations take longer due to access and setup. We quote the time estimate in writing along with the price.
We carry Abatement Technologies-compatible foaming agents, low-pressure rinse wands, fin combs, and drain pan liners on every truck. For standard residential units, we don’t need to order anything. Specialty HEPA-Care configurations in commercial settings sometimes require a 24-hour parts pull, but we know that before we quote and we say so upfront.
