Air Balance

A thorough certified air balance should be performed after an HVAC system is installed, modified or control systems are upgraded to ensure that it is operating according to the design criteria, manufacturer's specifications, and NEBB standards for high-performance building systems.

Hydronic Balance

A comprehensive hydronic balance should be performed after a cooling or heating system is installed to ensure that it is operating according to the manufacturer's specifications and the system is operating in accordance with the design intent. A complete hydronic system balance includes temperature performance testing of all heat exchange equipment.

Sound and vibration Testing

To ensure occupant comfort and mitigate noisy HVAC systems, sound and vibration testing measures the performance of HVAC equipment against the manufacturer's specifications. This process may uncover potential installation or operating issues.

Control system verification

A meticulously balanced system will not perform as intended without a commissioned control program. A detailed control system verification program will ensure that the HVAC system is functioning as intended and that the building automation system graphical user interface accurately represent the associated equipment.

Fume hood certification

DAC offers complete fume hood testing and certification services to ensure safe operating conditions in laboratory facilities and provide effective, economical fume hood performance. Fume hoods should be routinely certified, at minimum, in 12-month intervals.

Stairwell Pressurization

DAC provides stairwell pressurization testing to ensure the operational reliability of this key component to the life safety system. This includes full compliance with local codes and ordinances to ensure compliance and the safety of building occupants.

Smoke Management systems testing

DAC performs smoke management systems testing to verify proper operation and provide a certified report detailing the system's performance levels.

Existing Infrastructure assessment

An existing system survey is a necessary first step if you are interested in improving an HVAC system to enhance efficiency, air quality, and/or comfort levels. DAC provides these assessments and works directly with our clients to identify options and opportunities unique to each facility and system.
