Check state requirements regarding licensure. Some states require HVAC workers to obtain certification. Specific requirements vary greatly. Some areas developed a test that applicants must pass, and others insist applicants gain experience through apprenticeship programs.
Investigate technical schools and colleges to find an HVAC program that fits your needs. Certification programs typically take about one year to complete, while associate degrees include general education courses such as composition, laboratory science, social studies and math and so take additional time, usually another year.
Contact schools to see if you can take individual classes rather than enroll in an entire program if you are just looking for information rather than professional certification. Programs with hands-on training often have limited space available.
Call local HVAC employers to see if you can shadow an employee or work as an apprentice, depending upon the level of involvement you want. Apprenticeship programs may require classroom work in addition to field training.
Apply for the program or classes. You will need to fill out forms to indicate your resident status. If you enter a degree program, you will have to take a basic skills exam.
Read the program's requirements carefully. Note the deadlines for withdrawing (if you discover the program isn't what you wanted), when coursework needs to be completed and the procedures for graduation.
