Depending on the state or granting organization, the cost of getting your HVAC license or certification may vary. Most of the time, the overall cost will range from a few hundred to a few thousand dollars. Standard expenses can include course registration fees, coursework and materials, examination fees, renewal fees, and possible reinstatement fees if your certification lapses or expires.

9. Difference Between HVAC License and HVAC Business License

Plumbing License

A business license is granted by government bodies that enable people or companies to conduct profit-generating activities within a geographical jurisdiction. It is the local government’s permission to set up a company. On the other hand, an HVAC certification proves that you have the necessary skills and training in your field.

Because a person obtains his HVAC license after completing his training program and earning his certification or degree, it’s a kind of post-graduate education. While this may seem like an unnecessary extra step, it is essential to note that most states require applicants to pass the license test before working independently in the sector to guarantee competence. Altogether, you may need an HVAC certification, HVAC license, and business license, although certification and licensing can be two separate things or interchangeable based on your state.
