How do you hire an HVAC technician? Sourcing, pay, screening and red flags

Your HVAC technician is the person who installs, maintains and repairs the heating, cooling and refrigeration equipment your customers pay you for — which makes them the direct producer of your service revenue.

The occupation sits exactly where your company does: in 2025, 68% of HVAC mechanic and installer jobs were with plumbing, heating and air-conditioning contractors, and another 6% were self-employed (BLS).

On top of the self-employed, BLS counted 409,670 wage-and-salary jobs in the occupation nationally in May 2025.

Schedule reality belongs in the posting, not in the fine print after the offer.

BLS says most HVAC technicians work full time, schedules may include evenings or weekends, they may be on call for emergencies, and they sometimes work overtime or irregular schedules during peak heating and cooling season.

Candidates price your on-call rotation in either way — state it up front.

Pick the level before you pick the person.

Three hiring shapes work:

• Apprentice or helper — you train. Apprentices learn under supervision, and the federal refrigerant rule is explicit: an uncertified apprentice may assist only while closely and continually supervised by a certified technician. The rule sets no time limit on that exemption, so supervision — not a calendar — decides when they go solo.
• School-trained entry tech — you finish the training. BLS says HVAC technicians typically need a postsecondary nondegree award (programs run 6 months to 2 years) followed by lengthy on-the-job training. They bring fundamentals and tool discipline; your senior techs bring your equipment and your customers.
• Experienced service tech — productive on a truck now. Judge them on the certification they hold (next section), the systems they have serviced, and references from previous employers.

The job-seeker-side description of the role — duties, tools, career path — is a career question, and it lives in our guide to what an HVAC technician does.

This page stays on the hiring decision.

One credential is federal law: EPA Section 608.

Under 40 CFR 82.161, any person who could reasonably be expected to violate the integrity of a refrigerant circuit while maintaining, servicing, repairing or disposing of appliances containing refrigerant must pass an exam from an EPA-approved technician certification program.

The certification comes in four levels, and the level decides what a tech may legally work on:

• Type I — small appliances: fully manufactured, charged and hermetically sealed in a factory with 5 pounds or less of refrigerant, such as window and portable ACs and PTACs.
• Type II — medium-, high- and very-high-pressure appliances, the category that covers residential split-system AC and heat pumps.
• Type III — low-pressure appliances such as chillers.
• Universal — all three types at once.

Tests are closed-book and proctored with a 70 percent pass mark (the mail-in Type I path passes at 84 percent), the certification does not expire, and EPA does not issue the cards — approved certifying organizations do.

Refrigerant purchasing is certification-gated too: only certified technicians may buy refrigerant, with limited exceptions — and your company may purchase if you give the wholesaler written evidence that you employ at least one certified technician.

Above that federal floor, licensing is a state-and-local question.

Whether your state also licences the technician individually — and at what level — is set by your state licensing board, or by your city or county where licensing is local.

Confirm what applies to your shop with the issuing body before you write it into a job posting, because the requirement your trucks must satisfy is the one your jurisdiction enforces.

The refrigerant transition changes the skills spec, not the certification.

Since January 1, 2025, new residential and light-commercial AC and heat-pump split systems may not be installed with refrigerant of GWP 700 or more (with a narrow exception for systems whose components were all made or imported before that date) — which is why R-410A (GWP 2,088) is being phased out of new installations of that equipment.

(VRF systems are excluded from that provision and have their own installation date of January 1, 2026.)

Existing systems may still be serviced and repaired for their whole useful life, including component replacement.

New equipment uses lower-GWP refrigerants such as R-454B (GWP 465) and R-32 (GWP 675), which EPA's SNAP rules list for new residential and light-commercial AC and heat pumps only, subject to use conditions.

The transition adds no federal certification: EPA's SNAP use conditions say technicians should obtain training consistent with UL 60335-2-40 Annex HH — a recommendation, not a requirement — and EPA says technicians already certified under 608 do not need to recertify.

Treat voluntary A2L courses as a plus on a resume, never as a legal requirement you must demand.

The dependable pipelines are the ones the trade already trains through:

• Registered apprenticeship programs. ABC's 67 chapters run more than 450 registered apprenticeship programs, and PHCC state chapters sponsor registered programs too — apprentices training through them need employing contractors. BLS points apprenticeship seekers to state employment services, state apprenticeship agencies, local contractors and union-management apprenticeship committees, and to apprenticeship.gov, which tells you where candidates gather on the other side of those doors.
• Veterans. SkillBridge lets employers become training providers and host service members in their last 180 days of service — a way to develop a tech before the vacancy even exists.
• Trade schools and association networks. EPA's approved 608 certifying programs include ACCA, the ESCO Institute, NATE, the PHCC Educational Foundation, RSES and the United Association — the schools and associations running those programs are where freshly certified candidates already are.

Sourcing is a standing task, not a when-someone-quits task: BLS projects employment of HVAC mechanics and installers to grow 10.9% from 2025 to 2035, against 3.5% for all occupations, with 40,600 openings a year.

Our research found no primary-source cost comparison between channels, so we will not invent one — budget by what each pipeline actually produces for your shop.

And post where techs already look: a complete posting on a board techs read beats a perfect post nobody sees.

You can see what candidates see on the HVAC technician jobs page.

Anchor the offer to the Bureau of Labor Statistics numbers, then adjust for your market and the tech's certification level.

For Heating, Air Conditioning, and Refrigeration Mechanics and Installers (SOC 49-9021), May 2025 OEWS:

• Median: $29.33/hour, $61,010/year
• 25th percentile: $23.25/hour ($48,360/year); 75th percentile: $37.05/hour ($77,060/year)
• 90th percentile: $45.78/hour ($95,210/year)

Three cautions when you use them.

First, there is no BLS starting-pay statistic — the closest proxies for an entry-level offer are the 10th percentile ($19.25/hour, $40,050/year) and the 25th.

Second, OEWS pay excludes overtime, shift differentials and non-production bonuses while including commissions and production bonuses, so a flat-rate tech working peak-season overtime can earn well above the measured figure.

Third, your competition is not only other contractors: the May 2025 median at plumbing, heating and air-conditioning contractors was $60,030, but wholesale trade paid HVAC mechanics a $71,190 median — your distributor's counter can outbid your truck.

Within the contractor industry itself (NAICS 238220), the median was $60,030 with the 90th percentile at $93,790.

State and metro figures for your market are on our HVAC technician salary page.

Pay plan is a separate decision from pay level — hourly, flat rate and commission each change what you owe at overtime, and none of them opts a technician out by itself.

For flat-rate (job-rate) techs, the regular rate is total job pay divided by hours actually worked, plus an extra half-time for each hour over 40; commissions count in the regular rate.

The narrow FLSA section 7(i) commission exemption requires a retail or service establishment, a regular rate above 1.5 times the minimum wage and more than half of pay from commissions — and whether an HVAC shop can use it has been decided case by case since DOL withdrew its old list of non-retail businesses in May 2020.

Price the plan with your bookkeeper and employment attorney before you promise a split.

Screen in a fixed order so every candidate clears the same gates:

• 1. Verify the certification they claim. Ask which 608 type they hold and which organization issued it. The certifying organization — not EPA — issues and replaces cards, and there is no EPA-run national lookup: since January 1, 2018, each certifying program must publish an online list of technicians it certified on or after January 1, 2017, though technicians may opt out. So take the card, note the issuer, and confirm through that program's list.
• 2. Verify any state or local licence with the issuing board's own lookup — not with a screenshot the candidate sends.
• 3. Test judgment on a real job. Have them talk through a diagnosis on equipment you actually service: what they check first, what they rule out, when they stop and escalate. The 608 Core exam covers recovery, recycling and reclaim, evacuation techniques and safety — hearing a candidate narrate that sequence on your own equipment tells you more than any quiz.
• 4. Map their training onto your trucks. The typical path is a postsecondary nondegree program of 6 months to 2 years followed by lengthy on-the-job training. Ask where they trained, then ask precisely what they can do unsupervised — the answer decides which calls you can dispatch them to alone.
• 5. Screen the customer conversation. Your tech quotes and explains work inside customers' homes. Have them explain a repair recommendation to you as if you were the homeowner, and listen for clarity, not just correctness.

One more compliance check: certification is not unconditional.

EPA may require a technician to demonstrate at their place of business that they can properly recover and recycle refrigerant, and may suspend or revoke a certificate for failing to do so or for violating the rule.

A tech who cannot walk the walk is more than a callback risk.

None of these is automatically a no — each is a reason to slow down and verify before you offer.

• Certification that cannot be documented. No card, or cannot name the certifying organization. Cards come from the certifying organization, so a candidate who cannot name theirs cannot be verified through it.
• The wrong 608 type for your work. Type I covers small appliances — factory-sealed units with 5 pounds or less of refrigerant. A tech holding only Type I is not your residential split-system service hire; that work sits under Type II.
• Drop-in refrigerant talk. SNAP and industry standards prohibit putting refrigerants such as R-454B into systems not designed for them. A candidate who pitches refitting old equipment with new refrigerant as routine is behind on the transition — and is proposing work SNAP and industry standards prohibit.
• Casual venting. Venting substitute refrigerants is prohibited under the Clean Air Act, where the maximum civil penalty is $124,426 for penalties assessed on or after January 8, 2025. "Everybody vents a little" is the most expensive sentence a candidate can say in an interview.
• Pay arrangements built to skip overtime. A proposal that a technician role be paid flat-rate or on commission with no overtime at all: the overtime calculation applies to flat-rate and commissioned techs unless a specific exemption applies, and the exemption HVAC shops sometimes assume has narrow tests and case-by-case status. Structure the plan with advice — not around the rule.
• Experience no reference will confirm. Years claimed but previous employers unreachable or vague. Ask for the equipment, refrigerant and system types they actually serviced — specifics survive reference checks, titles do not.
• Schedule mismatch discovered late. Evenings, weekends, on-call and peak-season surges are structural in this trade. A candidate who balks when first hearing your rotation will balk again in July — cover the schedule in the interview, not the exit interview.

The first 90 days decide whether the hire becomes a productive truck or your next opening.

Structure them:

Week 1 — the compliance file.

Copy the new tech's 608 certificate into your records: certified technicians must keep a copy of their certificate at their place of business, and keep it until three years after they stop working as a technician.

Having it on file also supports your refrigerant purchases — a company may buy refrigerant when it gives the wholesaler written evidence that it employs at least one certified technician.

Complete whatever registration your state board or local jurisdiction requires, confirming the requirement with the issuing body rather than assuming.

Weeks 2–4 — ride-alongs.

Your trucks, your customers, your call sequence.

If the hire is an apprentice or otherwise uncertified, refrigerant work happens only under the close, continual supervision of a certified technician — the exemption has no time limit, but the supervision is the rule, not a formality, and the supervising technician shares responsibility for compliance.

Months 2–3 — supervised solo and a real checkpoint.

Move the tech to solo calls your service manager reviews, and hold a 90-day review against what the job actually requires: quality of the diagnosis, callbacks, paperwork.

If your shop installs new residential or light-commercial equipment, the units going in now carry lower-GWP refrigerants such as R-454B and R-32 — federal law does not require a separate certification for them, but EPA's use conditions say technicians should obtain training consistent with UL 60335-2-40 Annex HH.

Schedule that training inside the 90 days, before the cooling season tests the tech instead.

Keep the recruiting math in front of you: BLS projects 40,600 openings a year for HVAC mechanics and installers through 2035, much of it from replacing workers who retire or change occupations, and growth is expected to come from commercial construction (including data centers), residential construction and retrofit/replacement work.

Every trained tech you have is hireable elsewhere — retention is the cheap half of hiring.

What moves a tech to stay:

• A pay path they can see. The BLS spread shows the room: from the $61,010 median to $77,060 at the 75th percentile and $95,210 at the 90th. Whatever plan you run, a tech should be able to see the next step and what earns it — a number they have to guess at is a number they will take somewhere else.
• A schedule that is honest and predictable. Evenings, weekends, on-call and peak-season overtime are structural in this trade. You cannot remove them, but rotating them fairly and publishing the rotation costs nothing and is remembered.
• Work that keeps up with the trade. The refrigerant transition is a development path as much as a compliance item — the techs trained on the new lower-GWP equipment are building the skill the next decade of installations runs on. Fund the training EPA's use conditions recommend, and treat certification as something the company invests in, not just verifies.

Hiring one role well is easier when the rest of the operation is set up for it — our guide to hiring HVAC and plumbing techs covers the cross-role work: job descriptions, pay plans, verification and onboarding that apply to both trades.

This page is employer career and business information, not legal advice. Certification requirements are set by the U.S. EPA; technician licensing by your state licensing board, or your city or county where licensing is local; and pay rules by federal and state wage law.
