HVAC Design & Drafting

Heating, Ventilation, and Air Conditioning (HVAC) is the technology of indoor environmental comfort that has now become the required industry standard for the construction of new buildings - Residential/Commercial, Hotels, Malls, Industrial units, Hospitals, Schools Etc.

HVAC system design is a sub discipline of mechanical engineering & effectively designing an HVAC system is of core importance to any project as HVAC Services alone consume more than 70% of Building power. Designing & selecting these Equipment’s to meet their utmost efficiencies is of prime importance.

Our course instills smart, sustainable technologies and offers hands-on experience to each & every candidate for their secured future.
