HVAC Design & Drafting Course
HVAC is the backbone of modern infrastructure, ensuring indoor comfort in residential, commercial, industrial, and institutional buildings. With HVAC systems responsible for over 70% of a building’s energy use, energy-efficient HVAC design, accurate equipment selection, and sustainable practices are essential to improve performance and lower operating costs.
Most academic courses lack real-world exposure to modern HVAC design tools and global industry standards. At Finnaire, we bridge this gap with practical, job-ready HVAC training programs that provide hands-on experience, advanced software training, and real project-based learning—preparing you for success in today’s dynamic HVAC industry.
