What should an HVAC technician job description include? (free template)

Duties and responsibilities.

Write the description before you advertise the job.

Under the Americans with Disabilities Act, essential functions are the fundamental duties of the position, not the marginal ones, and a written description prepared before advertising or interviewing is evidence of what is essential — a function can be essential because the job exists to perform it, because few employees are available to share it, or because it is highly specialised.

If you need the day-to-day definition of the role first, the HVAC technician career guide covers what the job is; this page stays on the employer's side of it.

Split the work the way your trucks actually run.

Residential or commercial.

Service and repair, installation and changeouts, or both.

Maintenance-agreement callbacks or new construction.

A tech who has run residential changeouts all year reads a commercial service posting as a different job, and vice versa, so the split is the fastest signal your posting gives about fit.

Then list the duties that make the job what it is at your shop: diagnosing failures, explaining repair options and pricing to customers, documenting work in your field software, keeping truck inventory straight.

Physical demands, stated plainly.

Before a conditional offer you may state the job's physical requirements — lifting a set weight, climbing ladders — and ask whether the applicant can meet them.

Putting them in the description does double duty: it tells candidates what the day costs their body, and it gives you compliant wording to screen on later.

Licence and certification requirements — worded exactly.

Never write a generic "must hold a state HVAC licence" line: only about a quarter of US jurisdictions (13, including D.C.) license HVAC workers at an apprentice, technician or journeyman rung — the rest license contractors only, license at the master level only, split the trade into fuel-gas, refrigeration and electrical pieces, or leave licensing to cities — and names and levels differ by state.

Georgia, for example, has no state licence for individual HVAC technicians — the state licenses conditioned air contractors (Class I and Class II).

Michigan does not issue a journeyman or technician licence for HVAC workers and licenses mechanical work only at the Mechanical Contractor level.

Write the exact licence class your state, or city, requires, with the state named, or use the placeholder line in the template below and fill it before you post.

Refrigerant work needs EPA 608 on top of any state licence.

Under the federal rule (40 CFR 82.161), anyone who could reasonably be expected to violate the integrity of the refrigerant circuit while maintaining, servicing, repairing or disposing of appliances containing CFC/HCFC or non-exempt substitute refrigerants, such as HFCs, must pass an exam from an EPA-approved technician certification program.

Ask for the type in the posting: Type II covers medium-, high- and very-high-pressure appliances — the category that includes residential split-system AC and heat pumps — and Universal covers all appliance types.

When you check the credential, note that the certifying organization issues and replaces the documentation; EPA does not issue the cards.

Pre-offer, you may ask applicants about required certifications and licences and have them describe or demonstrate how they would do the work — how to check each credential at its source is our guide to verifying licences before you hire.

Verify before you post.

Licence classes and thresholds change, and licensing is often local.

Confirm the requirements for your jobs with your state's licensing board — or the city and county where licensing is local — and treat this page as employer information, not legal advice.

Pay and pay-plan disclosure.

Post a real range — the low, the high, and how the plan works.

A number of states now require the range in the posting itself.

As of September 2026, statutes confirmed to require a pay range in job postings include California (employers with 15 or more employees), Colorado, Washington State (15 or more), the District of Columbia, Maryland, Maine (10 or more, from July 29, 2026), Massachusetts (25 or more), Minnesota (30 or more), Illinois (15 or more), New Jersey (10 or more), New York (4 or more), Vermont (5 or more) and Virginia (from July 1, 2026).

Delaware's law is signed but does not take effect until September 2027.

Connecticut and Rhode Island do not require the range in the posting but require the wage range on request, by the time of an offer, or before pay is discussed.

Our research did not confirm posting requirements in Hawaii or Nevada, and city ordinances — New York City among them — were outside this check, so verify each state, and city, where the job is located.

Several of these laws reach past the number.

Colorado requires a benefits description and how and when to apply in every posting; Illinois lets a hyperlink to a public page carrying the pay scale and benefits satisfy the rule; Minnesota and Washington require a general description of benefits; Washington, D.C. requires the minimum and maximum projected pay in every listing and disclosure of healthcare benefits before the first interview.

If the job is paid on commission, say so in the posting.

New York's labor department requires it — postings must clearly state if a position is commission-based — and Vermont goes the other way: an ad for a job paid on commission, in whole or in part, need only disclose that fact and may skip the range.

Name the pay plan itself: hourly, flat rate, commission, salary, or a mix.

Whatever the mix, the federal Fair Labor Standards Act follows the pay, not the posting.

Flat-rate pay does not remove overtime — for 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 — and commissions count toward the regular rate too.

The narrow overtime exemption for commissioned employees of a retail or service establishment applies only when the regular rate exceeds 1.5 times the minimum wage and more than half the pay over a representative period of at least one month is commissions.

If you are not sure how your plan treats overtime, resolve that before you write the posting, not after a tech works a flat-rate summer week.

For the market numbers behind the range — median wages and percentiles, nationally and by state — use our HVAC technician salary page rather than a competitor's ad.

Schedule, on-call, truck and tools.

These four lines filter more techs than any perk, so state each one instead of letting the new hire discover it.

Schedule: give the working days and hours and the honest seasonal shape of the work — if summer means six-day weeks, say that here.

On-call: say whether there is a rotation, how often it lands on one tech, and how after-hours call-outs are paid, with that pay treatment in the pay section rather than nowhere.

Truck and tools: say whether the truck is company-provided and whether it goes home with the tech, what the company supplies — fuel card, tablets, large and specialty tools — and what the tech is expected to bring, such as hand tools and gauges.

If you fund certifications or licence renewals, name it; techs read paid renewals as a signal you run a legitimate shop.

Good HVAC technicians read postings the way managers wish candidates read resumes: fast, and looking for reasons to stop.

The fastest reasons to stop are all fixable in the copy.

No pay range.

Techs shop jobs on pay, and a posting that hides the number reads as a number worth hiding.

In the states listed above it is also a legal exposure, not just a conversion problem.

A licence line that fits no state.

A generic "must hold a state HVAC licence" tells a Georgia tech — whose state licenses conditioned air contractors rather than individual technicians — that you have not checked your own market, and it gives a Michigan mechanical contractor nothing to act on.

Name the licence class and the state, or state plainly that you will help the right candidate obtain it.

Age-coded wording.

Terms like "young", "recent college graduate", "boy" or "girl" violate age-discrimination rules unless a statutory exception applies, and help-wanted ads may not show a preference for, or discourage, applicants based on race, color, religion, sex, national origin, age 40 or older, disability or genetic information.

Describe the work, not the person you imagine doing it.

Questions the posting cannot ask.

Stating the physical demands and asking whether the applicant can meet them is allowed.

Asking about past job injuries or workers' compensation history before an offer is not — keep those questions out of the posting, the application form and the phone screen.

Referral-only hiring.

Recruiting mainly by word of mouth through a mostly one-group workforce can itself be discriminatory if almost all hires come from that group.

Post the job publicly.

And if you screen with a skills test, a test with adverse impact on a race, sex or ethnic group is treated as discriminatory under the Uniform Guidelines on Employee Selection Procedures unless it has been validated.

Small-shop assumptions.

Federal EEO laws cover private employers with 15 or more employees and the age law those with 20 or more, but state laws often cover smaller shops, so check yours.

Federal contractors must include the equal-consideration tagline in job ads; many other employers add an equal-opportunity line voluntarily.

With the copy fixed, put the posting where techs actually look: browse current HVAC technician jobs to see what candidates see on the board.

When you are ready to run the full process, our guide to how to hire an HVAC technician covers sourcing, screening, pay and the first 90 days, and onboarding new technicians is what turns a good posting into a retention story.
