State Licensing vs. National Certification
Important: Most states require hvac contractors to have a state license IN ADDITION to national certifications. National certifications demonstrate skill and knowledge; state licenses give you legal authorization to work and pull permits.
Check your state's requirements in our state licensing guides. Many states recognize national certifications as partial exam waivers or experience documentation.
