Abatement Technologies Coil Cleaning: The Dallas Owner’s Guide
CleanRun stocks and installs coil cleaning for Abatement Technologies negative-air machines and HEPA filtration systems used in Dallas residential and light commercial jobs. Typical installed service runs $280-$480 for a full coil cleaning on an Abatement Technologies PRED750 or CAP600-series unit, and we can usually get to it within 24-48 hours of your call. Most owners figure out something’s wrong when the unit pulls noticeably less airflow or the HEPA alarm trips during a duct cleaning run - the coil is choked with construction dust, mold, or the greasy residue that builds up fast in Dallas’s humid months.
Which Abatement Technologies Models This Applies To
We regularly clean coils on the PRED750, PRED1200, CAP600-UV, and HEPA-AIRE SAH2 series - the four units we see most often in Dallas homes, especially in the Design District and Oak Cliff where older buildings get retrofitted with abatement-grade systems. The coil sits behind the pre-filter bank; on most Abatement Technologies units, the model plate is on the blower housing side, not the control panel side, which trips up some owners.
Here’s how to tell what you’ve got: the PRED series uses a 16x20x1 coil footprint, while the CAP600-UV takes a deeper 20x25x2. The HEPA-AIRE SAH2 has a split-coil design that’s easy to identify by the two access panels. We clean both OEM Abatement Technologies coils and quality aftermarket equivalents from CoilGuard and ThermoFlo - the aftermarket units match the fin density (12 fins per inch on the PRED750, 14 on the CAP600) but run about 30% less on parts cost. For warranty-holding units still under Abatement Technologies service coverage, we note the OEM preference in our written scope so you can decide before we start. CleanRun is an independent service provider, not affiliated with Abatement Technologies.
Signs Your Abatement Technologies Coil Cleaning Is Failing

- Reduced suction at the hose whip. The manometer on your unit reads normal, but the actual airflow at the duct register feels weak. That’s usually a coil choked with compacted debris - the blower works harder, draws the same amps, but can’t push through the restriction.
- HEPA filter alarm trips early or repeatedly. The differential pressure sensor thinks the HEPA is loaded, but the filter’s got hours left. What it’s actually reading is back-pressure from a dirty coil upstream, a misdirection that costs owners unnecessary filter swaps.
- Musty or sour smell during operation. Dallas humidity runs 60-70% from May through October. A coil with organic buildup becomes a breeding surface; the smell hits when the unit first kicks on and the blower aerosolizes what’s living in the fins.
- Ice formation on the coil housing in cooling mode. Restricted airflow across a dirty coil drops the surface temperature below dew point, then below freezing. We’ve pulled units in Lakewood and Preston Hollow with 1/4-inch ice sheets that the owner thought meant a refrigerant leak.
- Unusual blower motor noise or heat. The motor’s working against a pressure wall. Amp draw climbs, bearings run hot, and the unit sounds like it’s laboring. Left long enough, you replace the motor too.

AfterReplacement Cost & What’s Included
Our written price for Abatement Technologies coil cleaning in Dallas breaks down as follows:
| Service | Price Range |
|---|---|
| Standard coil cleaning (PRED750, PRED1200) | $280-$360 |
| Deep coil cleaning with foaming agent (CAP600-UV, heavy buildup) | $340-$480 |
| Coil replacement with OEM part (if fins are corroded or damaged) | $520-$780 |
| Aftermarket coil replacement (CoilGuard/ThermoFlo equivalent) | $420-$620 |
What drives the range: accessibility (some units are ceiling-hung in commercial spaces), fin condition (bent or corroded fins need more labor), and whether we’re also replacing the pre-filter and HEPA as part of the same visit. Every price is written and agreed before work starts - Haven Standard Clause 1 - and includes the Documented Photo Record of the coil before and after. The 365-Day Done Right Promise covers the workmanship; parts carry their manufacturer’s warranty, which we note on your job record.
DIY or Call Us?

An owner can safely check the pre-filter, verify the model plate, and look for obvious ice or debris on the coil face. What we don’t recommend: pulling the coil bank without locking out power properly, using a pressure washer on aluminum fins (they fold at 40 PSI), or attempting to straighten damaged fins with a kitchen knife. The Abatement Technologies CAP600-UV has a 240V blower section that stays hot for ten minutes after disconnect - we’ve seen that surprise homeowners.
We carry foaming cleaner, fin combs, and replacement coils for the PRED and CAP series on every truck. If the coil’s beyond cleaning, we can swap it same visit. Call (469) 405-6133 and we’ll confirm your model and give you a written price before we dispatch.
FAQs
In Dallas’s climate, with proper filter maintenance, five to seven years is realistic. Without regular pre-filter changes, three years is more common because the coil becomes the filter. Call (469) 405-6133 and we’ll check yours against that timeline.
Corroded or separated fins can’t be restored; cleaning works when the aluminum is intact and the tubes aren’t leaking. We photograph the coil and show you the condition before recommending either path.
Most coil cleanings run 90 minutes to two hours. A full replacement on a ceiling-hung unit might stretch to three hours. We put the duration in writing with the price.
We carry cleaning supplies, fin combs, and replacement coils for the PRED750, PRED1200, and CAP600-UV on every Dallas truck. Less common HEPA-AIRE SAH2 split-coils we can source within 24 hours if not in stock.
