National True-Test's Team


Billy C. Bivins III leads the National True-Test team in providing accurate testing and balancing of commercial HVAC systems. He oversees the test and balance of projects ranging from hospitals that are over a million square feet to office buildings, freestanding medical buildings, banks and schools. He performs work primarily in the southeast but works throughout the US and does work internationally as well.

He is a certified NEBB Professional who has been with National True-Test since 2004. He holds the following certifications: Test, Adjust & Balance, Sound Measurement, Vibration Measurement and Building Enclosure Testing. He is also a member of the ASHRAE organization.

Billy graduated with a bachelor’s degree in Mechanical Engineering from Auburn University. He earned the Engineer in Training (EIT) Certification. He has also completed the 10-hour Occupational Safety & Health Administration (OSHA) Hazard Recognition Training and he holds the rank of Eagle Scout.

“When a problem with an HVAC system presents itself, I view it as an opportunity to find the solution. Challenges are one of the most rewarding parts of the job because I pride myself in overcoming them to provide a solution.”

In the rare occurrence when Billy isn’t working, he can be found mountain biking, taking his jeep for a spin or doing yardwork. Snow skiing, serving on the parking team at his church and spending time with his family and friends rounds out his free time.

Austin Swindle joined the National True-Test team in 2017. He brought with him a control background which made it easy for him to transition into the test and balance field. Austin performs test and balance for all types of buildings including medical facilities, universities, office buildings, banks and restaurants, but hospitals are his specialty.

Austin is a NEBB Certified Technician who has also completed the 10-hour OSHA Hazard Recognition Training.

“My favorite part of working at NT-T is the environment. It’s more like a family than business.”

Austin enjoys fishing in lakes and has won multiple tournaments. When he’s not working or competing in fishing tournaments, he enjoys spending time with his wife and friends.

Dylan Willcutt joined the National True-Test team after working 5 years in the construction field as a plumber. Dylan performs test and balance work in a variety of buildings but working in hospitals is one of his favorite job sites because of all the different people he has the opportunity to meet.

“I really like the traveling part of the test and balance work. It’s great to see new places and different things.”

Dylan completed the 10-hour OSHA Hazard Recognition Training.

“I have never seen a more involved work/family than NT-T. They always exceed expectations whether it be for the workers, job site, or serving the Lord in any way they can. I love working here and couldn’t thank God enough for putting me in the path of National True-Test.”

Outside of work, Dylan can be found out on the lake fishing or enjoying just about any type of outdoor activity. He also enjoys spending time with his wife, friends and family.

Isaac Darty earned a degree in Applied Science in Industrial Electronics Technology from Shelton State Community College. He brought with him experience in preventative maintenance of robots and other machinery.

Isaac holds a certification in KUKA Kore Robotics. He has also completed the 10-hour OSHA Hazard Recognition Training.

"The decision to join the NT-T team has proven to be a blessing. One of my favorite things about the team is how everyone works together to complete the task at hand."

Outside of work, Isaac enjoys hunting, fishing, and spending time with his family.

Jacob Bivins joined the National True-Test team in 2009. He reviews the mechanical drawings to create bids for upcoming projects. Jacob also sets up jobs and creates the electronic reports for the technicians to use when they are recording the test and balance data on jobsites. Upon completion of the projects, Jacob assembles reports before their final submission.

Jacob attended Jefferson State Community College where he earned a degree in Computer-Aided Drafting (CAD) and Design. He also graduated from Wallace State Community College with a Technical degree in Heating, Air Conditioning and Refrigeration.

Jacob completed the 30-hour OSHA Hazard Recognition Training and he is EPA Certified.

“I enjoy setting up jobs that include hospitals, schools, military bases and churches. It’s rewarding to see how the engineer’s design for the HVAC systems becomes a reality when our technicians ensure the building is properly balanced per the required specifications.”

When Jacob isn’t working, he can be found trail riding, camping, or hanging out with friends. He enjoys spending time in the great outdoors and spending time with his yellow Labrador retriever.

Stephanie Bivins manages the daily operations of the National True-Test office. She ensures everything runs smoothly and that each task is performed with excellence. She processes contracts, sends test and balance reports, bids, invoices and handles the accounting aspect of the business.

When Stephanie joined National True-Test, she brought experience in finance, marketing and office management. Stephanie graduated Cum Laude from Auburn University with a Bachelor of Arts degree in Public Relations. Prior to working at National True-Test, Stephanie worked as an office manager at a home security company in the Birmingham area.

“One of the best parts of being on the National True-Test team is having the opportunity to work with the amazing Owners, Contractors and Mechanical Contractors who allow us to partner with them to perform their test and balance work.”

“I also could not ask to work with a kinder, more thorough and efficient team who strives to deliver accurate test and balance reports with excellence at all times. I am grateful to be a part of a team who values honesty and hard work.”

In Stephanie’s free time, she can be found outside running, kayaking, hiking, or reading in her hammock. Traveling is another passion of hers and some of her most memorable trips include backpacking on mission trips, scuba diving anywhere in the Caribbean and snow skiing out west. Spending time with her husband and pets is also one of her favorite activities.
