How long does it take to get an HVAC contractor license in Idaho?

The full path from apprentice to licensed contractor typically takes 6-7 years: approximately 4 years as a registered apprentice (8,000 hours + 576 classroom hours to qualify for journeyman), then 2+ years as a licensed journeyman before you can apply for the contractor license. This is the minimum; many contractors take longer depending on work availability and exam preparation.

What exams are required for Idaho HVAC licensing?

Idaho requires a written exam at both the journeyman and contractor levels. Both exams are open-book and administered by Pearson VUE. The exam fee is $100 per attempt. Exams test Idaho-specific code knowledge and HVAC technical knowledge. As of 2025, Idaho does not require continuing education for license renewals.

Is a bond required for Idaho HVAC contractors?

Yes. An Idaho HVAC Contractor License requires a $2,000 compliance bond. The bond protects clients in the event of code violations or incomplete work. The annual premium for a $2,000 bond is typically $50-$200 depending on your credit history. The bond must remain active throughout the license period.

Does Idaho require EPA 608 certification for HVAC technicians?

Can I do HVAC work in Idaho without a license?

No. Idaho requires licensing at every level of HVAC work – apprentice, journeyman, and contractor.
