HVAC Design and Drafting

HVAC Design and Drafting

COURSE OVERVIEW

HVAC Design and Drafting course is designed for Engineering/Diploma graduates who wants to build a career in the Construction field as HVAC Engineers. HVAC stands for Heating, Ventilation, and Air Conditioning. The system is used to provide heating and cooling services to buildings.

HVAC systems have become the required industry standard for construction of new buildings. Heating, Ventilation and Air Conditioning (HVAC) is a profession of providing human comfort by installing AC systems. It not only provides human comfort, but is also used in storage industry. HVAC is one of the most popular fields among Mechanical/Civil degree and diploma holders.
