HVAC Basics
The purpose of Heating, Ventilation and Air Conditioning (HVAC) systems is to provide environments that are comfortable for people and allow temperature- or humidity- sensitive equipment to operate safely and reliably. HVAC systems are used in residential, commercial and industrial facilities. This module will identify safe work practices to use when working around HVAC systems and the most common HVAC system components.

Sample Video Transcript
The purpose of heating, ventilation, and air conditioning, or HVAC systems is to provide environments that are comfortable for people, and allow temperature, or humidity sensitive equipment to operate safely, and reliably. HVAC systems are used in residential, commercial, and industrial facilities. An HVAC system is simply a group of components working together to condition the air in an enclosed space. The components insure that the sir in this space is clean and odor free. And its temperature, humidity, and movement are maintained within desired ranges.
