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 HVAC Cleaning in Rockville: What to Know First
We provide independent Abatement Technologies HVAC cleaning in Rockville, MD, with most evaporator coil, blower, and air handler jobs completed in a single scheduled visit. Every job starts with a written price before any panel comes off, and ends with a documented photo record of every component we touched. If you own an Abatement Technologies HEPA-AIRE or Predator series system, or any of their portable or truck-mounted air scrubbing equipment tied into your home’s forced-air setup, we clean it to manufacturer tolerance without voiding your warranty. Call (240) 255-4519 for a free written estimate. The photo comes first. The price comes after.
How Abatement Technologies Products Fail - and How We Fix Them
- HEPA-AIRE PAS2400 blower motor housing - grease and drywall dust caking. These portable units see heavy use in Rockville renovation jobs, and when they’re tied back into residential HVAC, the blower wheel loads up with fine construction debris that the standard 1-inch pleated filter won’t catch. We remove the housing, clean the wheel with controlled negative-pressure extraction (suction that pulls debris out rather than pushing it deeper), and photograph the gap between before and after.
- Predator 1200 series evaporator coil - fin corrosion from Montgomery County’s chloramine-treated water. The coil’s aluminum fins react with chloramine over seasons, shedding oxide flakes that collect in the condensate pan and restrict airflow. We apply a foaming cleaner rated for aluminum, rinse with low-pressure water, and document fin density recovery in the photo record.
- Abatement Technologies air handler cabinet - microbial growth on the insulation liner. The foil-faced liner in older PAS series handlers delaminates near the coil, trapping moisture. We don’t paint over it. We remove degraded sections, treat the substrate, and replace with closed-cell material that won’t wick water.
- Truck-mounted HEPA system crossover ducting - flexible trunk collapse in Rockville’s freeze-thaw cycle. When Abatement Technologies truck units feed permanent home ductwork through transitional flex, the material fatigues in unconditioned attic spaces. We inspect with a borescope, mark the failed section, and replace with insulated hard pipe where the run allows.
- Predator 600 series - heat exchanger soot staining from short-cycling in tight homes. These smaller units get oversized for the load in new Rockville construction. Incomplete combustion leaves carbon residue we remove with soft-bristle mechanical cleaning, then we flag the underlying sizing issue in the written job record for your HVAC contractor’s review.
Our Abatement Technologies HVAC Cleaning Process
- 1
System shutdown and access. We lock out power, remove service panels, and identify the unit model and serial for the job record.
- 2
Visual inspection with borescope and camera. Every evaporator coil, blower wheel, and heat exchanger surface is photographed before contact. You see what we see before any price is written.
- 3
Written scope and price delivered. Haven Standard Clause 1: the price is fixed per system, agreed in writing, before work starts. No per-vent arithmetic, no add-ons after the fact.
- 4
Component-level cleaning. We select the method - foaming cleaner, mechanical brushing, or negative-pressure extraction - based on what the Abatement Technologies unit actually needs and what its materials will tolerate.
- 5
Post-clean testing and photo record. We run the system through a full cycle, check static pressure where accessible, and deliver before-and-after photos of every cleaned component as a standard deliverable.
- 6
365-Day Done Right Promise activation. The written guarantee goes into your job file. If it’s not right, we make it right.

Why Rockville Homeowners Call CleanRun Air Duct Cleaning Rockville for Abatement Technologies Work
We’ve been running jobs across Rockville since 2013, including plenty of work in the older split-levels near Congressional Plaza where the original flex duct tends to show its age in ways that aren’t obvious until you pull the register cover. Tomas Reyes and our crew know Abatement Technologies equipment from renovation-site portable units through permanent residential installs. When a Predator series coil needs cleaning, we don’t guess at fin spacing or cleaner compatibility - we document, verify, and clean to the material’s tolerance. Our equipment roster includes Abatement Technologies, Rotobrush, Nikro, Honeywell, Aprilaire, and Guardsman, so if your system integrates multiple brands, we’re not learning on your job. The 365-Day Done Right Promise, the documented photo record, and the written upfront price are standard on every visit, not exceptions. Haven Standard Clause 3: Verified Crews - background-checked, uniformed, identified by name before arrival.
FAQs
No, routine maintenance and cleaning performed by a qualified independent technician does not void your Abatement Technologies warranty, provided no components are altered or replaced with incompatible parts. We document every step and use manufacturer-specified methods so your warranty record stays clean. Call (240) 255-4519 if you’d like us to review your warranty terms before scheduling.
Restricted airflow from a dirty coil or blower wheel persists even with a new filter, and you’ll often notice longer run times or uneven temperatures between rooms. We inspect with a borescope before quoting - if the debris isn’t visible in the image, we won’t charge as though it is. Call (240) 255-4519 for a free inspection.
For consumables like filters and gaskets, quality aftermarket parts meeting the same MERV and temperature specs are typically fine and carry no warranty risk. For proprietary components - certain Predator series control boards or HEPA-AIRE motor assemblies - we source OEM or cross-reference equivalents and note the choice in your written job record. We never substitute without documenting why.
Every three to five years for typical residential use; every two to three years if you run portable Abatement Technologies units through your home ductwork after renovation or remediation jobs. Montgomery County’s pollen load and the freeze-thaw debris that gets pulled into attic air handlers push Rockville homes toward the shorter end of that range. Call (240) 255-4519 and we’ll set a schedule based on your actual usage.
Yes. Haven Standard Clause 1 includes our Free Second Opinion on any written estimate. Bring us a competitor’s quote for the same repair; we’ll put our number next to it in writing, no charge. The 365-Day Done Right Promise covers the work either way.
