HVAC license requirements by state

Do you know your state's HVAC license requirements? HVAC licenses can vary wildly from state to state, all with different rules and requirements. Some states may reciprocate licenses from other specific states.  Meanwhile, other states may not require a license at all— or they may require a license locally. To ease the confusion, we've compiled a full list of HVAC license requirements by state.

Why Become Certified

Some states may not have requirements for HVAC licenses. For example, Colorado doesn’t require a state license although it’s possible to become certified through a recognized industry or trade organization.However, it's generally a good idea to obtain a professional certification even if your state doesn't require it. Becoming certified gives HVAC businesses a number of competitive advantages, like helping increase sales. When potential clients are choosing a company, certifications can assure them your company has the most qualified technicians to complete a job. This can give clients the final push they need to choose you over a competitor.

Additional HVAC Certification Requirements

In addition to state requirements, the EPA requires all HVAC technicians to take an exam for handling refrigerant. The test covers topics like compliance and leak repair requirements in order to protect the environment. Technicians will then receive a Section 608 Technician Certification that lasts for life and doesn't require renewal.
