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.
Abatement Technologies Coil Cleaning: The Leesburg Owner’s Guide
Abatement Technologies coil cleaning in Leesburg typically runs $340-$620 for a full evaporator or condenser coil service, depending on accessibility and contamination level. We stock Abatement Technologies-compatible cleaning agents and tools on our Leesburg trucks, and most residential coil jobs are completed in a single visit. The camera goes in before the quote comes out - every time.
Most Leesburg homeowners realize their Abatement Technologies system’s coil needs attention when the upstairs never reaches set temperature despite the compressor running continuously, or when their energy bill spikes during a humid July without any thermostat change. In neighborhoods like Lansdowne and Beacon Hill, we regularly find coils that haven’t been accessed since the original construction crew closed up the basement ceiling.
Which Abatement Technologies Models This Applies To
Abatement Technologies builds coil housings across several product families, and the cleaning approach differs by series. The CAP600-UV and CAP1200-UV air purification systems use integrated evaporator coils with 16×20 or 20×25 inch footprints that sit directly above the plenum (the main distribution box where conditioned air splits into duct runs). The HEPA-Care HC500 and HC800 series use a separate coil module with a slide-track mounting that requires partial disassembly of the return air cabinet to access properly.
To identify your exact configuration, check the specification label on the coil housing itself - not the blower motor label, which is what most homeowners photograph first. The coil label lists the fin density (typically 8-14 fins per inch on residential Abatement Technologies units) and the refrigerant connection size. OEM cleaning protocols from Abatement Technologies specify pH-neutral foaming agents for their coated aluminum fins; we’ve found that generic alkaline cleaners strip the factory corrosion treatment within two to three applications, which is why we stock Abatement Technologies-formulated cleaner on every Leesburg truck. For units out of factory warranty, we also carry a quality aftermarket equivalent from Guardsman that meets the same pH specification at a lower parts cost.
Signs Your Abatement Technologies Coil Cleaning Is Failing

- Ice formation on the evaporator coil. When the coil surface is clogged with dust and biological growth, airflow drops below the threshold needed to keep coil temperature above freezing. The ice builds progressively, and by the time a Leesburg homeowner notices reduced airflow at the registers, the ice layer can be an inch thick.
- Musty or sour odor when the system cycles on. Abatement Technologies coils with UV-C lamp integration are designed to suppress microbial growth, but when the lamp expires at 9,000-12,000 hours and the coil hasn’t been cleaned, the combination of moisture and organic debris creates a biofilm that standard filters won’t capture.
- System runs longer to reach temperature. A clean Abatement Technologies coil transfers heat at the design rate of 400-450 CFM per ton. With fin blockage, that rate drops 30-40 percent, so the compressor runs 50 percent longer for the same cooling output - directly visible on the Dominion Energy bill.
- Water staining or rust below the air handler. The condensate pan beneath an Abatement Technologies coil is sized for normal drainage volume. When a dirty coil sheds excess water during defrost or when biofilm clogs the drain line, overflow follows. In Leesburg’s limestone-heavy water supply, that overflow leaves distinctive orange-brown staining on concrete basement floors.
- UV-C lamp appears dim or dark during operation. The lamp inspection window on CAP-series units should show a distinct blue-violet glow. A dark or flickering lamp has lost germicidal output, which accelerates coil contamination and indicates the unit is overdue for combined lamp and coil service.

AfterReplacement Cost & What’s Included
For Leesburg homeowners, Abatement Technologies coil cleaning breaks down as follows:
| Service Level | Price Range | What’s Included |
|---|---|---|
| Standard evaporator coil cleaning | $340-$480 | Access panel removal, foaming chemical application, fin straightening, condensate pan treatment, before/after photo record |
| Condenser coil (outdoor unit) | $280-$420 | Fin combing, refrigerant line inspection, cabinet cleaning, photo documentation |
| Combined evaporator + condenser | $520-$620 | Both coils, UV-C lamp status check, full system photo record, written scope summary |
| UV-C lamp replacement (if needed) | $85-$140 | OEM-spec lamp, installation, disposal of expired unit |
The range reflects three factors: coil accessibility (a ceiling-mounted air handler in a finished Leesburg basement takes longer than a closet unit), fin damage requiring comb restoration, and whether the condensate drain needs separate clearing. Every price is written and agreed before work starts - Haven Standard Clause 1 - and every job includes our Documented Photo Record of the coil condition before and after. The 365-Day Done Right Promise covers the workmanship; if contamination returns due to cleaning deficiency, we return at no charge.
DIY or Call Us?

What a Leesburg homeowner can safely check: verify the thermostat is set to Cool, confirm the outdoor disconnect switch is on, and inspect the condensate drain line for visible clogs at the exterior termination. These checks take five minutes and rule out the obvious.
Where DIY goes wrong: Abatement Technologies coil fins are aluminum, 0.006 inch thick, and deform permanently under pressure from a standard vacuum brush or compressed air nozzle held too close. We’ve replaced entire coil assemblies in Leesburg homes where a homeowner’s “gentle cleaning” collapsed three rows of fins and restricted airflow worse than the original dirt. The foaming agents matter too - household degreasers attack the hydrophilic coating that helps condensate sheet off the coil rather than bead and blow into the ductwork.
There’s no electrical lockout danger in simply looking, but accessing the evaporator coil requires removing sealed panels and disturbing refrigerant line insulation. If you see ice, oil staining, or hear hissing, stop and call. For everything else, (571) 487-7204 reaches our live answering line, and we’ll schedule a written-estimate visit.
FAQs
In Leesburg’s climate, with pollen seasons running March through June and high humidity July through September, a properly cleaned coil stays clear 18-24 months with standard 1-inch pleated filters changed every 60-90 days. Homes with pets or near active construction may need annual service. Call (571) 487-7204 and we’ll check your filter schedule against your actual coil condition - estimates are free.
No - “repair” isn’t the right term for coil contamination. The choice is between cleaning (restoring the existing coil) and replacement (when fins are corroded through or the copper tubing has leaked). In our Leesburg jobs, roughly 15 percent of Abatement Technologies coils we access are past cleaning and need replacement; the other 85 percent restore fully with proper chemical and mechanical service. We show you the photo evidence before recommending either path.
A standard residential Abatement Technologies evaporator coil cleaning takes 90-120 minutes from panel removal to system restart. Condenser coils run 60-90 minutes. Combined service is typically a half-day appointment. We don’t schedule overlapping jobs, so the technician who starts your work finishes it - Haven Standard Clause 3: Verified Crews.
Yes - our Leesburg trucks carry Abatement Technologies-spec foaming cleaner, fin combs sized for their fin density, replacement UV-C lamps for CAP-series units, and compatible drain pan treatment tablets. We also stock parts for Lennox, Trane, and Carrier systems. CleanRun is an independent service provider; we are not affiliated with Abatement Technologies, though our technicians train on their published service protocols.
