2024 Test and Balance Report.pdf

This is a Room Air Change Certification Report for the Whiteriver Indian Health Service facility located at 200 W. Hospital Dr., Whiteriver, Arizona 85941, dated May 10, 2024. The report was prepared by Arizona Air Balance Company (Tempe, Arizona) with engineer AMG Company (San Clemente, California). The certification verifies room airflow and air change rates in accordance with ANSI/ASHRAE/ASHE Standard 170-2017 and AABC (Associated Air Balance Council) National Standards for independent services.

The report includes detailed room-by-room verification data for 23 areas within the facility, documenting room properties (square footage, cubic footage), required and actual air changes per hour, airflow rates (supply, return, and exhaust in CFM), and pressurization measurements. Testing was conducted on May 10, 2024, using an Evergreen Electronic Micromanometer calibrated for velocity and volume measurements. Key findings indicate that most rooms passed certification requirements, though several rooms are flagged with notes regarding damper adjustments, exhaust airflow modifications, and system rebalancing needs. Rooms with deficiencies include several isolation rooms, a decontamination area, and supply processing areas that require corrective maintenance work order WKD0922851 to achieve full compliance with pressurization and air change rate requirements.
