Particle count excursions
Loaded ductwork sheds particulate the moment airflow changes, pushing classified rooms out of spec mid-campaign.
Cleanrooms & Biological Laboratories · Metro Atlanta, GA
Regulatory compliance, operational continuity and verified air quality — delivered with zero disruption to your cleanrooms & labs operation in Metro Atlanta, GA. Certified crews, engineered containment, and a documented report at handover.

Cleanrooms & labs in Metro Atlanta, GA share a specific set of failure modes in their HVAC systems. Below are the four we are called about most, and the standards that govern how each one has to be corrected and documented.
Loaded ductwork sheds particulate the moment airflow changes, pushing classified rooms out of spec mid-campaign.
Restricted returns and fouled coils stretch recovery time past the qualification limit.
Shared returns move biological load between rooms that are supposed to be independent.
Uncontrolled cleaning forces a full requalification instead of a targeted one.
| Standard | How it applies |
|---|---|
| ISO 14644 | Cleanroom air-cleanliness classification and monitoring expectations. |
| IICRC-certified source removal | Verified source removal on supply, return and AHU components. |
| ASHRAE 62.1 | Ventilation rate and filtration baseline for occupied lab space. |
| OSHA / EPA | Registered antimicrobial use and technician protection during biological work. |
Licensed mold remediation inside ductwork, air handlers and affected building cavities, under engineered containment with clearance verification.
Every project follows the same sequence, whether it is one air handler or a full campus. Each step produces evidence that ends up in your handover report.
Every system is filmed before a brush touches it. The baseline footage sets the scope, identifies damage and closed dampers, and becomes the first half of your before/after record.
Work zones are isolated and held under negative pressure with HEPA-filtered machines, so debris leaves through the equipment instead of into the occupied building.
Rotary brushes, air whips and compressed-air tools release bonded debris while the vacuum holds continuous capture — source removal, not surface dusting.
Once the system is physically clean, labeled antimicrobial chemistry is applied to duct interiors, coils and pans, with product, dilution and dwell time logged.
Post-clean camera footage, airflow readings and particle counts are compiled into one report with technician credentials, standards applied and a floor-plan reference.
We scope the work so it does not. Terminal filters stay undisturbed, containment is built upstream, and we coordinate with your validation group so any testing is targeted to affected rooms rather than the whole suite.
Yes. We record a baseline count per classified room, repeat it after the system is cleaned and balanced, and hand over both sets with the technician log and camera footage.
Both are scoped. Remediation without a moisture-source fix fails within a season, so the report names the cause — a failed pan, a duct leak, an unbalanced return, a humidity problem — and what it takes to correct it.
Post-remediation verification is standard. For projects where an independent clearance is required, we coordinate with a third-party hygienist so the verification is not performed by the company doing the remediation.
Yes. Most commercial work in Metro Atlanta runs outside normal operating hours. We build the schedule around your occupancy and hand each area back clean and ready for use before your team returns.
