Licensing pointers
Federal EPA Section 608 rules require certification for technicians who maintain, service, repair or dispose of equipment that could release refrigerants (epa.gov/section608). State and local HVAC licensing varies, so check your state board.
Federal EPA Section 608 rules require certification for technicians who maintain, service, repair or dispose of equipment that could release refrigerants (epa.gov/section608). OSHA heat guidance: osha.gov/heat-exposure. Some states have their own heat rules, so check with your state's workplace safety agency too.
Rules vary by state, county and city. Confirm with your state board or agency before you start. This isn't legal advice.
Insurance to ask about
- Ask your employer what coverage applies while you're an apprentice or employee
- If you go independent later: general liability, commercial auto, tools coverage, workers' compensation once you hire
- Ask about any license bond your state or city requires for contractors
Equipment and tools to research
- Tools your employer or program lists
- Protective gear
- Gauges and recovery equipment as you advance
- Reliable vehicle
