HVAC technician careers for veterans: the fastest-growing trade on our list
Of the twelve trades we cover, heating, air conditioning and refrigeration has the fastest projected growth. It also has the most flexible entry: a 6-month to 2-year school program, an apprenticeship, or both.

Start with the outlook
BLS projects employment of heating, air conditioning and refrigeration mechanics and installers to grow 11% between 2025 and 2035, against 3% for all occupations[2]. That is the highest growth rate among the twelve trades we track; lineworkers (10%) and electricians (9%) are next. BLS expects about 40,600 openings a year over the decade, most of them from workers retiring or changing occupations[2].

BLS Occupational Outlook Handbook profile: Heating, Air Conditioning, and Refrigeration Mechanics and Installers[2]. OOH job counts include self-employed workers and, for some profiles, related occupations, so they run higher than the OEWS wage-survey count above. Openings include replacement of workers who retire or change occupations, which is why they exceed net growth.
Growth rate is only part of the picture. A trade growing quickly from a small base can still produce fewer openings than a slow-growing large one: welding grows at 2% but has nearly as many openings a year as HVAC. What the HVAC number tells you is that the field is adding positions, not only refilling them, which tends to mean more employers willing to train newcomers.
Two ways in, and they can be combined
BLS describes HVAC as a trade where many people start in a postsecondary program, lasting from 6 months to 2 years, that ends in a certificate or associate's degree. Others train through an apprenticeship that usually lasts several years and combines paid on-the-job training with technical instruction each year[2]. Neither path is required to the exclusion of the other. Some veterans use a short school program first and then join an employer as a trainee.
The GI Bill treats the two routes differently. A school program is paid as tuition and fees with a housing allowance for the months you are enrolled. An approved apprenticeship or on-the-job program pays you a housing amount that steps down over time while the employer pays your wage. The GI Bill apprenticeship pay guide walks through that taper.
2,436 GI Bill-approved HVAC programs show in VA's GI Bill Comparison Tool, including 903 listed as on-the-job training or apprenticeship and 1,533 as school-based non-college-degree programs[3].
Counts compiled from the public Comparison Tool data on October 29, 2026 by an affiliated site (see disclosure). Approval status changes; confirm a specific employer or school in the tool before you rely on it.
HVAC is one of the few trades where VA's list is weighted toward schools rather than employers: fewer than four in ten approved programs are on-the-job training. That reflects how the trade is usually entered, and it means a veteran looking specifically for a paid apprenticeship has fewer listings to choose from than an electrician or plumber would.
The one certification almost everyone needs
The Environmental Protection Agency requires nearly all HVAC technicians to be certified in proper refrigerant handling, and BLS notes that the exam is typically included in a postsecondary HVACR program[2]. Some states and localities also license HVAC technicians, and many manufacturers and industry groups offer optional certifications that some employers prefer or require[2]. Check your state's rules through CareerOneStop's License Finder before you choose a program[4].
If you maintained environmental control units, refrigeration plants or shore-based air conditioning in the service, check whether your training included refrigerant certification. If it did, get a copy of the card before you separate; it is evidence a civilian employer can verify.

Pay: lower ceiling than the electrical trades, steady middle
The median HVAC technician earned $61,010 in May 2025[1]. The middle half of the field earned between $48,360 and $77,060, and the 90th percentile was $95,210. Compared with electricians and plumbers, the median is a few thousand dollars lower and the top end is lower by more than $10,000, while the bottom of the range is similar.
- 10th percentile$40,050 $19.25/hr
- 25th percentile$48,360 $23.25/hr
- Median$61,010 $29.33/hr
- 75th percentile$77,060 $37.05/hr
- 90th percentile$95,210 $45.78/hr
Spread from 10th to 90th percentile: $55,160. The 90th-percentile worker earns 2.4× the 10th. Mean annual wage: $64,780. Employment covered by the survey: 409,670 (wage and salary jobs; excludes the self-employed).
The highest state median was in the District of Columbia at $84,390, followed by Alaska, Illinois, Massachusetts and Connecticut, all above $76,000[6]. Florida had more HVAC jobs than any other state and an above-average concentration, which fits a cooling-heavy climate.

| North Carolina | 15,230 | $57,260 | 1.17 |
Together these 6 states hold 40% of the national total. Location quotient above 1.0 means the trade is a larger share of local jobs than nationally[6].
A practical sequence
From separation to working technician
- Check whether your military training already gave you EPA refrigerant certification, and get a copy of the card.
- Decide between a short school program and an employer apprenticeship; compare the GI Bill treatment of each.
- If you choose school, confirm in VA's GI Bill Comparison Tool that it is approved and that it prepares you for the EPA exam.
- If you choose an apprenticeship, ask the employer whether the program is registered and VA-approved for on-the-job training.
- Look up your state's HVAC licensing rules, if any, before you commit to a location.
- Add manufacturer or industry certifications once you know which equipment your employer services.
