HVAC Certification

Guide to HVAC Certification & Licensing

One of the last, and most-important steps in becoming a heating, ventilation and air conditioning technician is earning your HVAC certification or license. While you may hear differing opinions on the necessity of this step, the truth of the matter is that there are far more reasons to become licensed and certified than there are not to.

Is HVAC Certification & Licensing Mandatory?

Guidelines for HVAC certification and licensing vary from state-to-state and, in many cases, industry-to-industry. In general, however, a good rule of thumb to remember is that your state will determine whether or not it’s mandatory that you become licensed, while employers and industry standards will usually dictate if a certification is required.
