Hi Emmanuel: Being an HVAC technician, is not boring at all, opposite to that, is a challenging career to develop your hands-on abilities and the thermodynamics knowledge you have acquired while in the school. And the HVAC technician earns a high amount of money a year, in such a way, that you would be able to create your own HVAC business, just by leading a team work to perform the tasks you previously calculated by using a HVAC simulation software. By the other side, you can work on a leading HVAC company, on the design, manufacturing or installation of refrigeration and ventilation equipment to be used in hospitals, schools, offices or any other building complex. You can go any further in your career provided you like this area of Mechanical Engineering, so feel motivated, look in the internet what are the requirements the HVAC leading companies look on their employees; about this, I can mention just a few companies: Carrier, Johnson Controls Inc., York, among others. Finally, you can work as a service or maintenance technician on HVAC equipment as well.
