Particle count excursions
Loaded ductwork sheds particulate the moment airflow changes, pushing classified rooms out of spec mid-campaign.

Risks and compliance drivers in cleanrooms & biological laboratories
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.
Recovery-time failures
Restricted returns and fouled coils stretch recovery time past the qualification limit.
Cross-contamination between suites
Shared returns move biological load between rooms that are supposed to be independent.
Requalification cost
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. |
What iaq & disinfection includes
Baseline indoor air quality testing, whole-system disinfection and a corrective plan that resolves sick building syndrome complaints at the source.
- Particle counts, CO2, temperature and relative humidity by zone
- Surface and air sampling where microbial growth is suspected
- System disinfection with EPA-registered chemistry
- Written corrective plan ranked by impact
Our five-step field process
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.
Fiber-optic & robotic camera inspection
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.
Negative pressure containment & HEPA filtration
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.
Mechanical agitation, brushing & vacuum extraction
Rotary brushes, air whips and compressed-air tools release bonded debris while the vacuum holds continuous capture — source removal, not surface dusting.
EPA-registered antimicrobial disinfection
Once the system is physically clean, labeled antimicrobial chemistry is applied to duct interiors, coils and pans, with product, dilution and dwell time logged.
Air quality audit & compliance report
Post-clean camera footage, airflow readings and particle counts are compiled into one report with technician credentials, standards applied and a floor-plan reference.
Cleanrooms & labs FAQ
Will duct cleaning force a cleanroom requalification?
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.
Do you take particle counts before and after?
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.
Can testing tell us why staff are complaining?
Usually yes. Complaint patterns map to measurable causes — low outdoor air, high CO2, humidity above 60 percent, or particulate from a fouled system. We test by zone and report which of those is driving your complaints.
Is disinfection alone enough?
No. Disinfecting a loaded system is temporary. Physical source removal comes first, disinfection second, and the ventilation issue that allowed the problem gets named in the corrective plan.
Do you work nights, weekends and shutdowns?
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.
