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

Duties and responsibilities.

Put the description in writing before the posting goes up.

The ADA treats the fundamental duties of a job as its essential functions, and a written description prepared before you advertise or interview is evidence of what is essential — a function can be essential because the position exists to perform it, because few employees are available to share it, or because it is highly specialised.

For a commercial technician, that written list doubles as your screening rubric: it is what you quiz candidates against and what the first review cycle measures.

Start from the occupation, then narrow it to your buildings.

O*NET defines the occupation — Heating, Air Conditioning, and Refrigeration Mechanics and Installers — as workers who install or repair heating, central air conditioning, HVAC or refrigeration systems, and BLS notes that some technicians specialize: commercial refrigeration is one named specialty, and some specialize in installation while others repair and maintain systems.

"Commercial HVAC technician" tells a candidate the market, not the job — your posting does that work.

Name the buildings (offices, schools, hospitals, retail, industrial — or your mix of them), the equipment your crews run — rooftop units, chillers, boilers, VAV systems, building controls — and whether the job is service and repair, maintenance-agreement work, new installation, or a mix of all three.

The worker-side version of this question — what the job is like day to day — belongs to our commercial HVAC technician career guide; this page stays on the employer's side.

Physical demands, stated plainly.

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

Writing them into the description tells candidates what the day costs their body and gives you wording you can screen on later.

For commercial work, say where the demands come from: rooftop access, mechanical rooms, ladder and lift work, or the weights your crews move.

Licence and certification requirements — worded exactly.

Do not write a generic "must hold a state HVAC licence" line: licence names come from each state's or city's own files, and as of September 2026 nine states — Alaska, Florida, Georgia, Hawaii, Louisiana, Michigan, Nevada, Ohio and Tennessee — have statewide HVAC licensing only at the contractor/business level, with no worker licence, so a requirement that fits nowhere reads to a working tech as an employer who never checked their own market.

The names differ enough to prove the point: states license HVAC work as "Air Conditioning and Refrigeration" in Texas, "Mechanical" classes in Michigan, Iowa, Oklahoma, New Mexico, Tennessee, Louisiana, Mississippi and South Carolina, "Conditioned Air" in Georgia, "Heating, Piping, Cooling" in Connecticut, "Heating" groups in North Carolina, and a separate "Refrigeration" licence in California (C-38), Massachusetts and North Carolina.

So use the template's placeholder until you have looked up the exact licence name and class your jobs need, with the issuing authority named, and if the right candidate could qualify after you hire them, say so — "or ability to obtain within [N] days" is an honest line.

The federal certification needs no lookup: under EPA rules, any person who could reasonably be expected to violate the integrity of a refrigerant circuit while maintaining, servicing, repairing or disposing of appliances containing regulated refrigerants must pass a test from an EPA-approved technician certification program.

Match the 608 type to the equipment in your buildings: Type II certification covers maintaining, servicing, repairing or disposing of medium-, high- and very-high-pressure appliances (the rule excepts small appliances, MVACs and MVAC-like appliances); Type III covers low-pressure appliances — for example, chillers using refrigerants such as R-11 and R-123; and Universal certification covers all appliance types across Types I, II and III.

Two details employers get wrong: EPA 608 certification does not expire, so do not ask for a "current" card; and apprentices are exempt from the certification only while closely and continually supervised by a certified technician — the rule sets no time limit on that exemption, so supervision is the condition, not tenure.

Internal level names are yours to define.

Our research found no primary source that defines tiers like "Tech I", "Tech II" or "senior" as a regulated ladder — they are employer job titles — so if you post for a numbered level, say in the posting what it means at your shop.

Before an offer you may ask applicants about required licences and certifications and ask them to describe or demonstrate how they would do a task; collect licence and certification numbers on the application so you can check each one, a step our guide to verifying a licence before you hire walks through.

Verify before you post.

Licensing for HVAC work is set state by state — under licence names and classes that differ by state — and by the cities and counties that issue licences where licensing is local, and the rules change.

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

The fuller licence, pay and screening picture sits in our guide to how to hire a commercial HVAC technician.

Pay and pay-plan disclosure.

Post a real range — the low, the high, and how the plan works — because in a number of states the range is a legal requirement in the posting itself, not a nice-to-have.

Laws confirmed in our research (September 2026, from statute text or the state labor agency) to require pay disclosure in job postings include California (employers with 15 or more employees), Colorado, Washington State (15 or more), the District of Columbia, Maryland (for work performed at least partly in the state), Maine (10 or more, since July 29, 2026), Massachusetts (25 or more in the state), Minnesota (30 or more in the state), Illinois (15 or more), New Jersey (10 or more, over 20 calendar weeks), New York (4 or more, for work performed at least partly in the state), Vermont (5 or more) and Virginia (since July 1, 2026).

Delaware's law is signed but does not take effect until September 2027, and it will not apply to employers with 25 or fewer employees.

Connecticut and Rhode Island do not require the range in the posting; each requires giving the applicant the wage range on request — by the time of an offer at the latest in Connecticut, and before pay is discussed in Rhode Island.

Our research did not confirm the posting requirement reported for Hawaii, and city ordinances were outside this check; our research produced no closed national list, so verify each state — and each city — where the job is located or where applicants will work.

The state-by-state detail lives in our guide to pay transparency laws by state.

Several of these laws reach past the number, so build the posting accordingly.

Colorado requires a benefits description and how and when to apply in every posting; Illinois (15 or more employees) accepts a hyperlink to a public page carrying the pay scale and benefits; Minnesota (30 or more in the state) and Washington (15 or more) require a general description of benefits in the posting; 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 — while 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 — and settle the overtime math before the posting, not after.

The federal Fair Labor Standards Act follows the pay, not the label: a flat-rate technician is still owed overtime — the regular rate is total job pay divided by hours actually worked, plus half-time for each hour over 40 in the workweek; commissions — including on equipment sales or service tickets — count in the regular rate; a bonus or spiff schedule announced in advance is a promised, non-discretionary bonus no matter what you call it; and the commission overtime exemption that can fit commission-heavy plans, section 7(i), applies only in a retail or service establishment, only when the regular rate exceeds 1.5 times the minimum wage and more than half of pay is commissions — whether a shop like yours qualifies is decided case by case.

Anchor the range to the market, then check it against your metro.

Our research found no commercial-specific BLS wage: residential and commercial work sit inside one occupation — Heating, Air Conditioning, and Refrigeration Mechanics and Installers (SOC 49-9021) — so every BLS OEWS figure is the whole-occupation band, not a commercial number.

Within that SOC, the median wage was $61,010 a year ($29.33 an hour) in May 2025, with the middle half earning between $48,360 and $77,060 — and those figures exclude overtime pay, shift differentials and nonproduction bonuses, so a tech who works heavy call-out hours can earn above them.

State-by-state numbers sit on our commercial HVAC technician salary page — use them rather than a competitor's ad.

Schedule, on-call, truck and tools.

State each of these instead of letting the new hire discover them.

Schedule: give the working days and hours and the honest shape of the year — BLS notes that most HVAC technicians work full time, that schedules may include evening or weekend shifts, and that technicians may need to be on call for emergencies — so if your rotation means standing night coverage or chiller-changeover weekends, write it 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 sitting in the pay section, not nowhere.

Our research found no primary source for typical on-call rotations or call volume in this trade — it varies by shop, which is exactly why your posting should say yours.

Truck and tools: say whether the shop provides a vehicle — and whether it goes home — or whether the crew meets at the shop and rides out together.

Draw the tools line explicitly: list the items the company supplies and the items the technician is expected to buy or bring, and keep each item on one side of the line — a posting that leaves it vague is how the first tool argument starts.

If you fund certification fees, licence renewals, factory training or a tool allowance, name it in the posting.

Each of the problems below lives in the copy, and each is yours to fix before you publish.

No pay range.

Where one of the posting laws above covers your shop, a posting without a range is a legal exposure — not a stylistic choice.

A licence line that fits nowhere.

A generic "state HVAC licence required" tells a working tech you have not checked your own market: in nine states statewide HVAC licensing sits only at the contractor/business level — no worker licence — and where licences exist the names differ by state.

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

A 608 line that does not match the equipment.

"EPA cert required" is as underspecified as no line at all — Type II covers medium-, high- and very-high-pressure appliances (the rule excepts small appliances, MVACs and MVAC-like appliances), Type III covers low-pressure appliances such as chillers, and Universal covers all appliance types across Types I, II and III.

Ask for the type your buildings actually need.

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 generally 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 picture 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.

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.

Screening rules you have not checked.

Background-check, ban-the-box and paid-sick-leave rules were not verified state by state in our research — confirm the rules that apply where you hire before you screen.

Eligibility verification, before the first day.

While applications come in, check whether your state mandates E-Verify.

Florida (private employers with 25 or more employees, since July 1, 2023) and North Carolina (25 or more in the state) require it for new hires; South Carolina requires every private employer to verify every new employee within three business days; and Arizona, Alabama and Mississippi require every employer to use it.

The thresholds reported for Georgia, Tennessee and Utah were not verified in our research, so check your state's current rule directly.

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

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

Before you publish, run the wording past our guide to how to write a job ad for HVAC technicians, and when the replies come in, how to hire a commercial HVAC technician picks up the rest: sourcing, screening, pay and the first review cycle.
