About the HVAC Exam
Heating, Ventilation, and Air Conditioning (HVAC) is the backbone of indoor comfort — keeping homes, workplaces, and vehicles at the right temperature with clean, healthy air. It blends engineering principles from thermodynamics, fluid mechanics, and heat transfer, and often includes refrigeration (HVACR).

The HVAC certification exam is your gateway to becoming a licensed or certified technician. It assesses your ability to install, maintain, troubleshoot, and repair HVAC systems. Passing shows employers you have the technical skills, problem-solving ability, and professionalism to succeed in this essential trade.
