About Us

Founded in 2013, Precision Flow Engineering has quickly established themselves as one of the most trusted names in independent or 3rd party TAB and Commissioning firms in the DFW area and beyond. We achieved certifications by the National Environmental Balancing Bureau (NEBB) in 2014 and the Associated Air Balancing Council (AABC) in 2018. We are now one of very few firms to be certified by both top certifying agencies in the country. Our firm’s President, Mr. Cody Shook has more than 22 years in the TAB and commissioning industries.

The mindset of our firm is that our clients and partners are essentially purchasing trust. Integrity is our top selling product followed closely by knowledge and experience. We utilize the very latest in technology and instrumentation to execute and carry out our work while maintaining the standards set forth by AABC, ACG, ASHRAE and NEBB.

It is the goal of our firm, on every project we engage in, to provide the building owner with the most optimum performance of their mechanical system. This is achieved first through understanding all aspects of the building design. We then apply a unique and rigorous process of testing, adjusting, balancing, calibrating and documenting all flows and variables of the mechanical system. This is where Precision Flow Engineering believes true mechanical system optimization is achieved. PFE makes it a priority to understand the building automation system and the sequences that govern every mode of temperature control. We apply a thorough and systematic approach to testing and verifying all sequences, temperature control modes, inputs, and the appropriate responses of the equipment.


We apply this methodology to:

  • Chilled Water Plants
  • Boiler Plants
  • Chilled and Hot Water Systems of all types
  • Critical Pressure Environments (Operating Rooms, Clean Rooms etc.)
  • Process and Industrial Pumping Systems
  • Variable Air Volume (VAV) systems DDC and Pneumatic
  • VRV/VRF Systems
  • Data Halls and White Spaces
  • Packaged Roof Top Units
  • Dx Split Systems


We have served but are not limited to the following industries and building types:

  • Healthcare
  • Laboratories
  • Educational
    • K-12
    • Higher Education
    • Private Schools
  • Defense
  • Data Centers
