2025 Test and Balance Report.pdf

This is a Room Air Change Certification Report prepared by Arizona Air Balance Company for the Whiteriver Indian Health Service facility located at 200 W. Hospital Drive, Whiteriver, Arizona 85941. The report, dated June 2, 2025 (Project #2762), documents certification testing and measurements of room air flow rates and air change rates in compliance with ANSI/ASHRAE/ASHE Standard 170-2017 and Associated Air Balance Council (AABC) National Standards for independent services.

The report includes detailed airflow verification data for 18 certified rooms within the facility, presenting measured air change rates, supply/return/exhaust airflow in cubic feet per minute (CFM), and pressurization requirements. All tested rooms achieved passing status as of the certification date. Key room types certified include soiled utility biohazards, isolation rooms, decontamination areas, operating rooms, and central supply areas. Measurements were conducted using an Evergreen Electronic Micromanometer (Model S-PVF-1, Serial #2000552C) that was calibrated on March 26, 2025, with calibration due March 26, 2027, traceable to NIST standards. The certification confirms that listed air flow rates and air changes measured on the test date meet specification requirements, though the report notes this is not a guarantee for continuing conditions and recertification may be necessary if HVAC system operations are affected by construction, filter loading, duct cleaning, or other factors.
