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.

AfterAbatement Technologies Coil Cleaning: The Austin Owner’s Guide
We stock and install Abatement Technologies-compatible coil cleaning for residential HVAC systems across Austin, with typical installed pricing between $340 and $620 depending on coil accessibility and contamination level. Most Abatement Technologies coil jobs we book are completed same-day because we carry the compatible foaming agents, fin combs, and protective treatments on every truck. Homeowners usually discover the problem when their upstairs never cools below 78 degrees despite the compressor running nonstop, or when they spot ice building on the refrigerant lines outside.
CleanRun Air Duct Cleaning Austin is an independent service provider, not affiliated with Abatement Technologies. We service equipment from multiple manufacturers, including Lennox, Trane, and Carrier, and our technicians are trained on each brand’s specific coil geometry and access requirements.
Which Abatement Technologies Models This Applies To
Abatement Technologies builds coil cleaning equipment primarily for the abatement and restoration trade, but their portable HEPA-AIRE systems and related HVAC components appear frequently in Austin homes built between 2015 and 2022, especially in master-planned communities like Mueller and Easton Park where builders specified abatement-grade air handling during construction. The model plate you’re looking for sits on the blower housing or coil cabinet, not the thermostat.
Key identifiers: the HEPA-AIRE PAS2400 and PAS1200 series use a 20×20 or 16×16 evaporator coil configuration with a distinct three-bolt access panel. The newer Guardian Air series switched to a slide-track panel in 2019. Measure your coil face before calling, not the cabinet. The actual fin pack is typically 1.5 to 2 inches smaller than the nominal cabinet dimension on all sides.
OEM Abatement Technologies foaming concentrate runs $45 to $68 per quart through industrial suppliers with a two-week lead time. We use a NSF-certified equivalent from the same chemical family that matches the manufacturer spec sheet for pH and surfactant load. The difference is delivery time and price, not performance. For fin straightening on damaged Abatement Technologies coils, we stock OEM-compatible fin combs in 8, 9, 10, 12, and 14 fins-per-inch because mismatched comb teeth will shear the aluminum and turn a cleanable coil into a replacement.
Signs Your Abatement Technologies Coil Cleaning Is Failing
- Uneven cooling across rooms. The coil’s upper fin pack is clogged with construction dust and pollen that settled during Austin’s spring cedar season. Restricted airflow across the top third of the coil forces the compressor to overwork while the lower rooms stay comfortable.
- Ice on refrigerant lines or the coil itself. When fins are packed tight enough to drop airflow below 350 CFM per ton, the coil surface temperature falls below freezing and condensate turns to ice. The ice then insulates the coil further, accelerating the freeze-up cycle.
- Musty or chemical odor from registers. Biofilm builds in the condensate pan and on wet fin surfaces when cleaning intervals stretch past three years in Austin’s humidity. Abatement Technologies coils run a deeper fin pack than standard residential equipment, so they hold moisture longer and grow odor-causing bacteria faster.
- Water staining around the air handler. The condensate drain line backs up because algae and construction debris from a dirty coil wash downstream and clog the trap. We see this most in Austin homes with attic units where the drain runs 20+ feet to an exterior soffit.
- Electric bill jumps 20% or more with no rate change. A contaminated coil forces the system to run longer cycles to hit thermostat setpoint. In July and August, when Austin’s outdoor ambient stays above 95 degrees for weeks, that extra runtime translates directly to kilowatt hours.
BeforeAfterReplacement Cost & What’s Included
| Service Level | Price Range | What’s Included |
|---|---|---|
| Standard coil cleaning (accessible attic or closet unit) | $340 - $480 | Full foaming treatment, fin straightening, condensate pan treatment, before/after photo record |
| Restricted-access coil (tight attic, platform mount, or rooftop) | $480 - $620 | Everything in standard plus additional labor for access, protective sheeting, and extended documentation |
| Coil replacement when cleaning is not viable | $1,200 - $2,400 | OEM or equivalent coil, recovery/recharge, brazing, pressure test, vacuum, and written warranty |
What drives the range: coil location (attic kneewall vs. garage closet), contamination depth (surface dust vs. embedded construction debris from a never-cleaned new build), and whether the coil fins are damaged enough to require combing or replacement. Every price is written and signed before work starts, per Haven Standard Clause 1. No per-vent add-ons, no equipment fees that appear after the crew arrives.
The 365-Day Done Right Promise covers all coil work. If airflow readings don’t improve or the ice returns, we return and make it right. The photo record from your job, delivered before we leave, documents the condition we found and the condition we left.
DIY or Call Us?
What you can safely check yourself: the filter (replace if it’s gray and opaque), the condensate drain line outside (wet/dry vac the end if it’s clogged), and the thermostat schedule (make sure someone didn’t set a 68-degree hold in August). These three checks solve about 15% of the “coil issue” calls we get.
Where DIY goes wrong: foaming cleaner from the hardware store is formulated for automotive radiators, not HVAC evaporators. The pH is too high for the aluminum-copper junctions in Abatement Technologies coils, and the surfactants leave a residue that attracts dust. We’ve replaced coils that were chemically etched by well-meaning homeowners. High-pressure water or compressed air bends the fins permanently; once fins are flattened past 50%, air won’t flow through regardless of how clean the surface looks.
And the refrigerant lines are under pressure. If you open the wrong panel or nick a line, you’re looking at a full recovery and recharge, not a cleaning.

FAQs
In Austin’s climate, with cedar pollen in winter, oak in spring, and constant dust from limestone geology, a properly cleaned coil stays efficient for 18 to 30 months. Homes near active construction or with pets at the shedding threshold need cleaning closer to the 18-month mark. Call (737) 243-9544 and we’ll put you on a maintenance schedule that matches your actual conditions, not a generic calendar.
No. “Repair” in this context means replacement. A contaminated coil can only be cleaned or swapped; there is no patch or sealant that restores fin geometry or removes embedded biofilm. If the fins are intact and the copper tubing shows no corrosion, cleaning is the right call. If the fins are deteriorated from age or chemical damage, replacement is the only lasting fix. We make that determination with a camera scope and tell you before quoting either option.
Most Abatement Technologies coil cleanings run 90 minutes to 2.5 hours from truck arrival to final airflow check. Restricted-access units in tight Austin attics take longer because we protect your insulation and flooring with sheeting before setting up equipment. The actual chemical dwell time is 15 minutes; the rest is access, documentation, and verification.
Yes. We carry Abatement Technologies-compatible foaming concentrate, fin combs in all standard FPI counts, condensate pan tablets, and protective treatments on every service truck. For coil replacement, we stock common Abatement Technologies coil dimensions and can source same-day from our Austin supplier for less common sizes. We do not make you wait for a parts run while your house warms up.
