FAQs
Is this the same as mechanical engineering?+
No. While it shares some principles, this program is highly specialized in heating, cooling, and ventilation systems, whereas mechanical engineering is much broader.
Will I need to work outdoors?+
Yes, part of the job often involves installing or repairing outdoor condenser units, sometimes in challenging weather conditions.
Is mathematics important in this program?+
Yes, you will need a solid grasp of applied mathematics and physics to understand thermodynamics and electrical loads.
Can I start my own business after graduating?+
Absolutely. Many graduates eventually start their own HVAC contracting or maintenance businesses.
What safety certifications will I need?+
You will typically need certification for handling refrigerants safely, as well as general occupational health and safety training.
