How Can I Work in HVAC Repair and Maintenance

Educational Options

HVAC training programs can be found at trade schools, technical colleges and some universities. While most programs are available at the certificate level, some schools might allow you to transfer your certificate credits to an associate degree program in HVAC or a bachelor's degree program in HVAC. These are hands-on courses of study that teach you how to service and test HVAC systems in residential and commercial structures. In particular, you'll learn about heat pumps, furnace types, air-conditioning units and electrical systems; the planning and design of different HVAC systems might also be covered.


Some states require HVAC technicians to have a professional certification or certificate. Although each state has its own licensing requirements, you might need to complete a formal apprenticeship program and pass a test. A state certification is also required if you want to buy or use refrigerants, which requires a passing score on a written exam.
