Every state in the U.S. is a little different when it comes to what’s required to attain an HVAC license. This includes differences in cost and who issues the license in each state.
Some states allow transferring a license from other states, this is called reciprocity. Others require licensed HVAC professionals from other states to start fresh and apply for a unique license for that state. Every state is a little different, that’s why we created this guide.
This complete guide will provide:
- A quick reference list of every U.S. state’s requirements
- A link to each state’s issuing body for an HVAC license
- Testing requirements to receive an HVAC license
- Any costs required when applying in each state
