What We Do


Air & Hydronic Balancing

All air and water flow volumes associated with the HVAC Systems are measured and adjusted with calibrated instruments to meet the design determined by the mechanical engineer’s design requirements.


Control System Verification

Correct operation of the Building Automation Control System and associated communication devices are verified, tested, calibrated and functionally tested during the testing and balancing process.


Cleanroom Performance Testing

Cleanrooms provide controlled environments that require strict certified performance testing and adjusting, including space leakage levels, progressive room pressurizations, HEPA filter leakage, air flow and pressure testing, and required Cleanroom air flow volumes.


Chiller And Cooling Tower Performance Testing

Chiller and Cooling Tower System testing and adjustments are performed to ensure optimum system performance and safety. Malfunctioning Chiller and Cooling Tower Systems can adversely affect the performance and energy consumption of the overall HVAC System.


Duct Pressure Testing

Duct leakage is a major contributor to overall poor system performance and available pressure inconsistencies to provide for the needed airflows, per the design requirements. With our duct pressure testing method we are able to quickly identify duct system leaks and assist the mechanical contractor to efficiently remedy them.


Fumehood Testing

Exhaust air volume and velocity measurements are taken to insure safety with proper fume hood exhaust for operator safety and assists in certification of the fume hood in order to meet design specifications for the lab space.


Indoor Environmental Testing

We perform a variety of indoor environmental testing including air flow tests to determine air changes per hour for specific occupancy functions. Improper ventilation and distribution is a cause of a poor indoor environment, which will affect employee comfort and productivity.


Sound And Vibration Testing

Design parameters for the occupied building spaces normally have specified noise and vibration level requirements. We provide testing which identifies the amount of noise and vibration that is permitted to enter the spaces from the HVAC equipment or diffuser/grille air velocities. Noise is measured in (SPL) Sound Pressure Levels with a calibrated SPL meter. This meter is used to confirm that the spaces are in agreement the design requirements. Equipment and System Vibration is measured similarly and recorded.


Pre-Construction Document Review

Our Pre-Construction Document Review provides for review to identify coordination issues and potential problems that will affect the balancing and system performance. This assists in the testing and balance phase of the project to provide a much more efficient process.


Building Systems Commissioning

After a thorough review of all building systems documentation, a commissioning plan is created to provide a clear process for verification of the installation, operation, and performance of the mechanical, electrical, plumbing, and control systems. The commissioning authority conducts site observations, meets with contractors, manages deficiency issues, oversees training for the facilities operator, and performs a 10-month post construction review. Finally, a commissioning report is provided to the owner and the design and construction teams documenting the entire commissioning process.

What are Others Saying About Us?

“PacTAB went above and beyond to ensure everyone was well coordinated and understood their roles and responsibilities. They also played a vital role in sharing information to the project team without requiring oversight from the mechanical team to manage the distribution channels. Most importantly,

PacTAB provided effective and timely feedback to the team that allowed us to be more productive.

I look forward to working with their team in the future.”

“I have been fortunate to have the opportunity to work with Steve Smith and the crew of technicians at Pacific Test & Balance.

When working with us, our subcontractors, and our clients, their solution-based approach is rarely found in today’s market.

Whether it has been a comfort cooling system balance, cleanroom, lab performance testing, or even a fireplace pressurization issue for a prominent hotel, the PacTAB team and Steve have excelled.”

“I have worked with PacTAB on multiple projects, primarily in the healthcare sector, over the course of the last couple of years. I have been tremendously pleased with PacTAB’s efforts.

They have been extremely collaborative, true team players, and solutions-oriented.

This collaborative spirit has become more and more rare in the current environment, so my dealings with PacTAB have truly been a breath of fresh air.”
