Frequently Asked Questions
Most maintenance mechanics complete a 4-year registered apprenticeship — typically 8000+ hours of paid on-the-job training plus 144 classroom hours per year. After completing the apprenticeship and passing the journeyman exam, you can work independently. Master-level certification (where applicable) usually takes another 2-4 years of journeyman experience.
No. Maintenance Mechanics do not require a four-year college degree. The standard credential is a journeyman license earned through a paid apprenticeship registered with the U.S. Department of Labor at https://www.apprenticeship.gov/. Some workers complete a 1- or 2-year certificate at a community or trade college before applying — but the journeyman license is what employers actually require.
Maintenance Mechanic apprentices typically start at $45,890 per year (10th percentile) and progress upward each year of the apprenticeship. By year 3, pay usually reaches the 50th percentile around $51,020. All training is paid — apprentices are W-2 employees of contractors or unions, not students paying tuition.
Common maintenance mechanic certifications include: Certified Maintenance & Reliability Technician (CMRT); OSHA 10/30-Hour; EPA Section 608 (for refrigerants); Boiler operator license. Most states also require a journeyman license; some have a separate master license for independent work.
Maintenance Mechanics earn a national median of $51,020 (Trade Pay Score grade C), wages have grown 4% over the past 5 years, and the BLS counts roughly 627,680 maintenance mechanic jobs nationwide.
