Info
HVAC School provides free, practical HVAC/R training—primarily for techs, by techs. We connect the “why” to the work: electrical, refrigeration, airflow, diagnostics, installation, commissioning, service, building science, and commercial refrigeration. You’ll find field demonstrations, 3D explanations, full classes, interviews, and honest conversations with people who do the work. Facts only become useful when you can apply them. Our goal is to help you understand the system, take better measurements, solve problems safely, and remain humble enough to keep learning.
