HVAC Systems and Functions

The video tutorial explains HVAC, which stands for Heating, Ventilation, and Air Conditioning. It covers how HVAC systems maintain temperature and air quality in closed spaces. Heating involves using AC in summer and heaters in winter, while ventilation ensures fresh air circulation to prevent discomfort from high carbon dioxide levels. Air conditioning filters dust and eliminates moisture to provide good quality air. The video concludes with a request for feedback to improve content quality.
