HVAC Qualification Pharmaceutical Checklist [FREE PDF]

HVAC qualification in pharmaceutical manufacturing facilities is a regulatory requirement under FDA 21 CFR 211.42 and EU GMP Annex 1 (2022), which mandate that heating, ventilation, and air conditioning systems be designed, qualified, and maintained to prevent contamination and cross-contamination. The HVAC system directly impacts cleanroom classification, environmental monitoring outcomes, and product quality, making its qualification a cornerstone of the facility's contamination control strate

Installation Qualification (IQ) - Documentation Review

Verify that all HVAC system components are installed per approved design specifications and engineering drawings.

Are approved P&ID (Piping and Instrumentation Diagrams) and engineering drawings available and version-controlled for the HVAC system?
Have all HVAC components (AHUs, filters, dampers, coils, ductwork) been verified against the approved vendor equipment list and purchase specifications?
Have HEPA filter integrity certificates and manufacturer's specifications been collected and filed for all installed filters?
Have material certifications (mill certificates) been obtained for all ductwork and verified as appropriate grade (e.g., 304/316L stainless steel or epoxy-coated galvanized) per design specification?
Have all instrumentation tags (temperature sensors, pressure transmitters, flow meters) been verified as installed per the approved instrument list?

HEPA Filter Integrity Testing

Perform in-situ HEPA filter integrity testing using aerosol challenge to confirm filter installation and integrity.

Was HEPA filter integrity testing performed using a photometer or laser particle counter with PAO/DOP aerosol challenge per ISO 14644-3 methodology?
Was upstream aerosol concentration confirmed to be within the validated challenge concentration range (typically 10-20 μg/L) before scanning?
Was each HEPA filter face scanned at a traverse speed of no more than 5 cm/s with the probe held 2-3 cm from the filter face?
Did all HEPA filters pass the integrity test with downstream penetration at or below the site-specified acceptance criterion?
Have HEPA filter test results been documented with filter tag number, location, upstream concentration, and peak downstream reading for each filter tested?
Was re-testing of any initially failed filters performed after repair or replacement, with results documented?

Airflow Volume and Velocity Measurements

Measure and verify supply air volumes, face velocities, and air change rates against design specifications.

Was supply air volume flow rate measured at each supply diffuser/grille using a calibrated balometer or anemometer?
Was unidirectional airflow velocity measured at the face of grade A laminar flow zones and confirmed to be within the range of 0.36-0.54 m/s ± 20%?
Was the air change rate per hour (ACH) calculated for each room and confirmed to meet or exceed the design specification?
Was total exhaust air volume measured and confirmed to be balanced against supply air to achieve the design pressure differential?
Was airflow parallelism (uniformity) verified for all grade A laminar flow zones using smoke visualization or equivalent method?

Room Pressure Differential Verification

Verify that pressure cascades between rooms of different classifications meet GMP requirements.

Were room pressure differentials measured between each adjacent pair of rooms in the pressure cascade using a calibrated Magnehelic gauge or electronic transmitter?
Did all pressure differentials meet the minimum acceptance criterion of ≥10 Pa (or site-specified value if greater) with all doors closed?
Were pressure readings recorded at a minimum of three time points over the measurement period to confirm stability?
Was the direction of airflow confirmed (from higher to lower grade) by smoke test or equivalent at each doorway transition?
Are continuous pressure monitoring alarms set to alert at ≥15% below the minimum accepted pressure differential set point?

Temperature and Humidity Control Verification

Verify that temperature and relative humidity are controlled and maintained within GMP-required ranges.

Were temperature readings taken at multiple locations and time points in each controlled room using calibrated reference probes?
Was the room temperature confirmed to be within the design specification range (typically 18-22°C for aseptic areas) at all measurement points?
Was relative humidity confirmed to be within the design specification (typically 30-65% RH for most classified areas) at all measurement points?
Were temperature and humidity loggers calibrated and within their calibration interval at the time of use?
Was the HVAC system challenged under worst-case conditions (maximum occupancy, equipment heat load) and results documented?

ISO Cleanroom Classification Particle Count Testing

Perform non-viable particle count testing to confirm ISO classification of each controlled environment.

Was particle count testing performed using a calibrated laser particle counter with a flow rate of at least 28.3 L/min (1 CFM)?
Was the number of sample locations calculated per ISO 14644-1 Annex B formula (based on room area) and the required minimum number of locations sampled?
Were particle counts measured in both at-rest and in-operation conditions for Grade A and B areas as required?
Did all rooms pass their respective ISO classification limits for both ≥0.5 μm and ≥5.0 μm particle sizes?
Were particle count data statistically evaluated (95% UCL per ISO 14644-1) and formal classification certificates issued for each room?

Room Recovery and Containment Testing

Verify HVAC system recovery time and containment effectiveness under challenge conditions.

Was airborne particle recovery (clean-up) time measured and confirmed to meet the 15-20 minute recovery specification per EU GMP Annex 1?
Was airflow containment between adjacent rooms verified under door-open conditions using smoke visualization?
Was the HVAC system tested under simulated failure mode (e.g., single AHU failure) to verify alarm response and impact on classified areas?
Were all BMS (Building Management System) alarms for temperature, humidity, pressure, and airflow verified to activate correctly at defined set points?
Has the completed qualification package been reviewed, approved, and signed by the responsible Validation Engineer and QA representative?

Qualification Summary and Periodic Review

Summarize qualification outcomes, identify open items, and confirm requirements for periodic requalification.

Have all qualification protocol deviations been documented, assessed, and formally dispositioned as acceptable or requiring additional testing?
Has the HVAC requalification frequency been defined (minimum annually for classified areas) and scheduled in the facility validation master plan?
Has a change control process been established to trigger requalification when HVAC system components are modified, replaced, or relocated?
Have all snag list items identified during qualification been assigned to responsible owners with target closure dates?
Has the qualification report been issued and filed in the site validation master file (VMF) and is it accessible for regulatory inspection?
