National picture for hvac technician
Of the 49 jurisdictions currently published in this dataset, 47 require a trade examination administered by PSI, Prometric, NASCLA, Pearson VUE, ICC, or the state board directly. 17 require an explicit surety bond filed with the regulator before the license issues, and 0 accept the NASCLA Accredited Examination as a path toward reciprocal licensure for this line of work. Where the regulator publishes a numeric threshold, the average documented experience requirement is 3.5 years.
The comparison above is generated at build time directly from the state license entries on this site. Every value is traceable to the regulator's published rule. If you spot a discrepancy, the state page is the source of truth and will be re-verified against the official source set.
Choosing where to license first
- Lowest barrier to entry: sort by initial fee and look closely at rows where Exam = No or the state is marked Local / municipal.
- Strongest reciprocity downstream: states marked NASCLA Accepted, because the same exam can unlock multiple jurisdictions later.
- Lowest upfront cost: focus on combinations with the smallest initial fee and no bond requirement.
- Fastest path to wallet card: compare the Time column, but remember that municipal programs can still involve multiple city registrations.
