HVAC
HVAC stands for Heating, Ventilation, and Air Conditioning. It refers to the various systems and technologies that control indoor temperature, humidity, and air quality in buildings. This field is essential in both residential and commercial construction, focusing on making indoor spaces comfortable and energy-efficient. When you see HVAC on a resume, it typically indicates experience with designing, installing, maintaining, or repairing these climate control systems. This could range from home heating and cooling units to complex industrial climate control systems in large buildings.
