1. Why We Created Free HVAC Training
The HVAC industry is constantly evolving.
New control technologies, communication protocols, energy efficiency regulations and building standards mean engineers must continually develop their knowledge.
Rather than keeping that knowledge behind paid training courses, we've decided to share our expertise openly through our YouTube channel.
Every video is built around practical engineering, helping viewers understand not only how HVAC systems work, but why they are designed in specific ways.
