What should an HVAC service 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.

Split the work the way your service trucks actually run.

Residential or commercial.

Emergency and repair calls, maintenance-agreement tune-ups, changeout support, or a mix.

A solo truck, or calls run alongside a lead tech.

A tech who has spent the year on residential repair calls inside occupied homes reads a commercial building-service posting as a different job, and the split is the fastest signal your posting gives about fit — if you are hiring for a residential HVAC service technician, say residential in the title and the first line.

Then list the duties that make a service truck what it is at your shop: diagnosing failures on the customer's equipment, explaining repair options and pricing to the customer, performing repairs and servicing maintenance agreements, documenting every job in your field software, keeping truck inventory straight.

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

Physical demands, stated plainly.

Before a conditional offer you may state the job's physical requirements — lifting a set weight, climbing ladders, attics and crawlspaces — 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, or county — requires, with the state named, or use the placeholder line in the template below and fill it in before you post.

Which licence applies to your hire is its own question; our guide to which license your hire needs works through it.

Refrigerant work is the federal floor for a service hire.

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 — which describes a service tech's ordinary Tuesday.

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

When you check the credential, two notes: the certifying organization issues and replaces the documentation — EPA does not issue the cards — and the certification does not expire, so it is a one-time verification, not an annual renewal.

Pre-offer, you may ask applicants about required certifications and licences and have them describe or demonstrate how they would do the work; our guide to verifying EPA 608 certification shows how to confirm the card at its source.

Verify before you post.

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

Confirm the requirements for your service trucks 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, in force since 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) and Vermont (5 or more), with Virginia in force since 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.

The state-by-state rules are in our guide to pay transparency laws by state.

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 any part of the job's pay is 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 service technician salary page rather than a competitor's ad, and our guide to tech pay plans: hourly, flat rate and commission for the plan structures themselves.

Schedule, on-call, truck and tools.

These four lines filter more service 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 — BLS describes the occupation's schedules as usually full time, often including evenings or weekends, with on-call duty for emergencies and overtime or irregular schedules during peak heating and cooling season — 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 service truck is company-provided and whether it goes home with the tech, what the company supplies — fuel card, tablet, refrigerant recovery equipment, 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 service 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, or a range with no plan behind it.

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

In the states above that require a posted range for an employer your size, that is a legal exposure, not just a conversion problem — and on a service truck, where commission or bonus layers can sit on top of hourly, a range with no plan description invites the candidate to assume the worst.

The on-call rotation discovered after the offer.

Service work lives on the rotation.

A candidate who learns the schedule during onboarding instead of in the posting is a short-timer; the honest rotation in the ad filters out the mismatches before they cost you a hire.

A service-and-install blur.

If the truck is service, say service.

A generic technician ad for a diagnosis-heavy service seat pulls installer applications, buries the candidates you want, and tells experienced service techs you are not sure what you are hiring for.

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.

One more check between the posting and the first day: E-Verify.

Florida requires it for private employers with 25 or more employees (since July 1, 2023); North Carolina for employers with 25 or more employees in the state; South Carolina for all private employers, within three business days of hire; Arizona for every employer, with the record kept; Alabama for every employer (since April 1, 2012); and Mississippi for every employer, for all new hires.

Our research did not confirm the reported thresholds in Georgia, Tennessee and Utah — check with each state.

Federal contractors with the FAR E-Verify clause must enroll within 30 days of award.
