How to get there
Typical education: High school diploma or equivalent
On-the-job training: Moderate-term on-the-job training
Starting from high school
- Complete on-the-job training (moderate-term on-the-job training)
- Earn industry-recognized certifications (EPA Section 608, ASE certifications, manufacturer-specific training)
- Complete OSHA 10-Hour or OSHA 30-Hour safety certification ($25–$200)
- Gain 1–2 years of supervised work experience
- Advance to journeyman level or specialized role
Start with a vocational program or community college certificate in your specialization. Many manufacturers (like HVAC companies, automotive brands) offer their own certification programs, some of which are free or employer-sponsored. The EPA Section 608 certification is required for anyone handling refrigerants. Apprenticeships through IBEW (electrical) or UA (plumbing/pipefitting) provide paid training.
Many employers provide paid training. Union apprenticeships are typically paid from day one. Trade school programs may require tuition.
Switching from another career
- Assess which of your existing skills transfer (many do — see below)
- Complete a short certification or orientation program (EPA Section 608, ASE certifications, manufacturer-specific training)
- Apply for entry-level or apprentice positions — highlight transferable skills
- Complete any required on-the-job training (often shortened for experienced workers)

If you've worked with your hands, operated equipment, or have any technical background, you're ahead of most applicants. Many skills transfer directly: diagnostic thinking from any troubleshooting role, tool familiarity from any trade, and safety awareness from any industrial setting. Companies are struggling to fill these positions and are often willing to train motivated career changers. Consider contacting local HVAC, electrical, or plumbing companies directly — many prefer to train their own staff.
Certification costs are typically self-funded, but some employers reimburse. Union programs are paid positions.
