HVAC Design is a domain of building services which is having huge demand throughout the world. HVAC stands for Heating Ventilation and Air Conditioning which maintain human comfort by controlling various properties of air. Every human needs comfort, in order to maintain comfort level in a closed room we need to calculate the amount of heat produced in a room.
HVAC industry offers good potential for numerous careers in various fields as in Design & Drafting, Execution & Maintenance, AC Technicians and sales & Marketing. Apart, it also provides scope even for self employment and entrepreneurship. HVAC industry can even thrive in times of poor economy. According to US Bureau of Labor Statistics, a typical Technician can earn around US $18 dollars per Hour, narrating the work and economical potential of the industry.
In the present scenario, the global Environmental Imbalances are creating a substantial hike in the use of air conditioning, transforming it from a luxury to a need. In an effort to “GO GREEN”, saving money to attain better comfort level for Spaces, making the consumers to Acquiring the HVAC Systems. According to a survey on job opportunities in the field of HVAC, there is a increase of 40% in the past five years which is expecting to be 34% more by 2020.
