Testimonial – Local 104 HVAC/R Training with Testo Instrumentation
“What stands out most is the moment when a student sees the data from the Testo tools, everything clicks, and their confidence takes off” – Chris Coatsworth, TAB Instructor
How Testo HVAC/R Tools Are Powering Real-World Training at Local 104
Interview Participants:
Chris Coatsworth, TAB Instructor
Nick Colon, Service Instructor
Instructor Background
At Local 104, Chris Coatsworth teaches Testing, Adjusting, and Balancing (TAB), while Nick Colon focuses on HVAC Service instruction. Together, they lead a comprehensive 5-year apprenticeship program covering everything from HVAC fundamentals to advanced building automation and commissioning.
Apprentices earn certifications such as OSHA 30, EPA 608, Brazing, HVAC Excellence, and multiple TABB credentials, while gaining 1,200 hours of hands-on instruction. Throughout this program, Testo tools are fully integrated into labs and field simulations.
Integration of Testo Tools
Testo instrumentation is used across all five years of training. From basic refrigerant cycle analysis in year one to advanced air balancing and commissioning in later years, students rely on Testo for real-time system diagnostics. Key tools include:
Testo 550s/557s Manifolds
Testo 400/440 Air Flow & IAQ Kits
Testo 300 Combustion Analyzers
Testo 420 Flow Hood
Smart Probes
Clamp Meters, Thermometers, Leak Detectors
The Bluetooth connectivity and live data from the Testo Smart App help students see system changes instantly, making theory easier to understand.
Teaching Impact
Using Testo tools has transformed how instructors teach technical concepts. Chris and Nick highlight that:
Students can see how systems respond in real time, which helps complex ideas—like superheat and subcooling—“click.”
The intuitive design of the tools reduces the learning curve, allowing students to focus more on diagnosing and less on tool operation.
Multiple probes connected at once give students a complete view of system performance, enhancing their troubleshooting skills.
Overcoming Training Challenges
A major challenge in HVAC education is keeping students engaged and helping them understand how systems operate. Testo tools help bridge that gap by making abstract concepts visual and interactive.
For example, when students struggled to grasp subcooling and superheat, instructors used a Testo manifold and app to show live data on a screen. As the system was adjusted, the students could watch values shift in real time—turning confusion into clarity.
Outcomes & Benefits
Improved Student Confidence: Apprentices trust the accuracy of Testo tools and gain confidence in evaluating systems.
Higher Engagement: Students are more involved in labs and ask deeper questions thanks to live data and visual learning.
Modernized Curriculum: The tools help keep the program current with industry standards and evolving technology.
Certification Readiness: Testo tools align closely with what students will use in the field, better preparing them for real jobs.
Preparing for the Field
Chris and Nick emphasize that Testo tools mirror what students will use on the job. Their intuitive design and mobile app integration allow students to create reports, document findings, and analyze system performance—just like they would in the field. Students also learn calibration processes and how to verify equipment performance, building a professional mindset early.
Final Thoughts
Testo has become a trusted educational partner at Local 104. The accuracy, reliability, and innovation of the tools support both instructors and apprentices. What stands out most is the moment when a student sees the data, everything clicks, and their confidence takes off. That "ah-ha" moment—made possible by Testo—is what makes teaching truly rewarding.
