HVAC Apprentice Job Description: Duties, Template, Interview Questions & Pay (2026)
An HVAC apprentice learns the heating, air conditioning and refrigeration trade on real jobs beside a certified technician while taking classes. This page has an HVAC apprentice job description template, the duties apprentices take on as they progress, what the EPA Section 608 rules allow an apprentice to do, pay data, and six interview questions with what a good answer sounds like.
HVAC apprentice duties
An HVAC apprentice learns the heating, air conditioning and refrigeration trade by working beside a certified technician on real installs and service calls, while taking classes. In the first months that means carrying equipment, running line sets and ductwork, cleaning up and watching; within a couple of seasons it means doing the maintenance visits, taking readings and helping diagnose faults under supervision.
BLS does not count apprentices separately: under the SOC classification principles, apprentices and trainees are classified with the occupation they are training for. The figures on this page are therefore for heating, air conditioning and refrigeration mechanics and installers (SOC 49-9021).
Typical HVAC apprentice duties, drawn from the O*NET task list and ordered roughly by when an apprentice takes them on:
- Loading and unloading equipment and materials, and keeping the van stocked
- Measuring, cutting, threading or bending pipe and tubing
- Mounting condensers, compressors and air handlers, and cutting or drilling openings for equipment
- Connecting equipment to fuel, water or refrigerant lines
- Installing and adjusting thermostats, humidistats and timers
- Testing circuits and components with electrical test equipment
- Testing lines and connections for leaks, and brazing or soldering joints
- Recording time, materials and faults on work orders
- Talking customers through what was found and what was done
Refrigerant work comes with a federal rule (below), and it is the one duty federal rules bar an uncertified apprentice from doing alone.
| Working conditions (HVACR mechanics and installers) | Share reporting it |
|---|---|
| Face-to-face discussions | 98% every day |
| Wearing common safety equipment | 88% every day |
| 79% every day | |
| Indoors, not environmentally controlled | 74% every day |
| Outdoors, exposed to all weather | 58% every day |
| In an enclosed vehicle | 58% every day |
| A 40-hour typical week | 83% |
Attics in July and rooftops in January are the job. BLS also says HVAC technicians have one of the highest rates of injuries and illnesses of all occupations, from electrical shock, burns and muscle strain. A posting that names the safety training and the PPE provided reads as a company that takes it seriously.
EPA Section 608 and the apprentice
The Environmental Protection Agency requires Section 608 certification for technicians who maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere. There are four types:
- Type I: servicing small appliances
- Type II: servicing or disposing of high- or very high-pressure appliances, except small appliances and motor vehicle air conditioning
- Type III: servicing or disposing of low-pressure appliances
- Universal: servicing all types of equipment
Certification requires passing an exam, and the EPA says Section 608 credentials do not expire. To get Universal certification the core section must be taken as a proctored exam; an open-book core test does not count toward Universal.
The rule that matters for apprentices is in 40 CFR 82.161: apprentices are exempt from the certification requirement provided they are closely and continually supervised by a certified technician while doing any work that could reasonably be expected to release refrigerant. The supervising technician and the apprentice share responsibility for compliance. So an uncertified apprentice can work on refrigerant circuits with a certified tech beside them, not alone. If you pay for the exam, say so in the posting.
How HVAC apprenticeship works
The Occupational Outlook Handbook says HVAC technicians usually train through a postsecondary program of 6 months to 2 years or an apprenticeship, which lasts several years and combines paid on-the-job training with technical instruction each year covering safety practices, blueprint reading and heating and cooling systems. Some states and localities also license HVAC technicians; check yours.
If you register your program with the Department of Labor or a state apprenticeship agency, the federal standards in 29 CFR 29.5 apply: at least 2,000 hours of on-the-job learning in total for a time-based program (or a competency-based or hybrid approach), a recommended minimum of 144 hours of related instruction for each year, and a progressively increasing wage schedule. That schedule is the most persuasive line in an apprentice ad.

Requirements: what to ask for, and what to drop
| Requirement | What to know |
|---|---|
| EPA 608 | Not required at hire for an apprentice, because apprentices under close supervision are exempt. Offer to pay for the exam instead of requiring it. |
| Experience | Ask for none. Trade school or mechanical experience is a plus. |
| Education | BLS lists a postsecondary nondegree award as typical entry education for HVAC technicians overall, but apprentices are usually hired before or during school. A high school diploma is the common minimum. |
| Driver’s license | Nearly always needed. Say whether the apprentice will drive company vehicles and what record your insurer requires. |
| Tools | Say what they must bring and what you supply. |
| Schedule | BLS notes schedules may include evening or weekend shifts, on-call work for emergencies and overtime during peak heating and cooling seasons. Say how on-call works for apprentices. |
Customizing it by setting
Residential service and replacement
Say the ratio of install to service work and whether apprentices move toward sales-assisted replacement jobs. If technicians earn commission or spiffs on replacements, say how apprentices share in it.
Commercial and refrigeration
Rooftop units, chillers and walk-in coolers mean more Type II and Type III work, more heights and more travel. Say which equipment and which certifications you will pay for.
Facilities and schools
Educational services employ 3 percent of HVAC technicians at a $62,520 median. Say the building types, the shifts and whether the role includes on-call.
What HVAC apprentices earn
BLS does not publish apprentice pay. HVACR mechanics and installers as a whole had a median wage of $61,010 a year, or $29.33 an hour, in May 2025; the lowest 10 percent earned less than $40,050 and the highest 10 percent more than $95,210. Apprentice wages start toward the bottom of that range and rise with the wage schedule.
| Industry (HVACR mechanics and installers) | Median annual wage (May 2025) | Share of employment |
|---|---|---|
| Wholesale trade | $71,190 | 3% |
| Retail trade | $62,830 | 3% |
| Educational services | $62,520 | 3% |
| Plumbing, heating and air-conditioning contractors | $60,030 | 68% |
There were 440,900 HVACR mechanics and installers in 2025. BLS projects employment to grow 11 percent to 489,100 by 2035, with about 40,600 openings a year. That growth is why contractors who train their own technicians stop competing for the same few experienced ones.
Interview questions for an HVAC apprentice
You are hiring for reliability, mechanical interest and how the person handles customers and heat. Six questions and what a good answer sounds like:
1. What have you fixed or built with your hands?
Good answers are specific: a car, a bike, a house project, a job. You are looking for curiosity about how things work.
2. How do you handle working in an attic in summer or on a roof in winter?
Honest answers win. Candidates who have done outdoor or physical work and can describe how they managed it are a safer bet than those who say it will be fine.
3. A homeowner asks you what is wrong with their system, and the technician is in the truck. What do you say?
A good answer: be polite, say the technician will explain, and go get them. You are checking that the apprentice will not guess or promise.
4. Why is it important to follow procedures when handling refrigerant?
No certification is needed to answer this. Good candidates mention safety, the environment or the law. Anyone already studying for the 608 exam will say more.
5. Tell me about a time you were late or missed work. What happened?
Everyone has one. Look for ownership and what changed afterward.
6. Where do you want to be in three years?
Running calls on their own, holding Universal certification, or moving into commercial work are strong answers. They show the candidate sees the path.

What it costs to reach an HVAC apprentice
The closest benchmark family is technician / mechanic, the family we use for HVAC technicians. It has a median cost per applicant of $13.41 on Meta across our managed campaigns, with the middle half between $7.40 and $23.58, a blended figure of $8.35 and a 16 percent apply rate. The all-role median is $13.88. Our benchmark does not report apprentice campaigns separately.
Apprentice ads reach a wider pool than technician ads because they do not screen on a credential. Keep the form to a few questions (driver’s license, availability, interest in the trade) and call back fast. Cost per applicant is not cost per hire.

The job description is not the job ad
The template is the document. The ad is for someone who has not thought about HVAC yet.
- First line: “Paid HVAC apprenticeship, $00/hr to start, we pay for your EPA 608.”
- Show where the wage schedule goes and when they get their own van.
- Say “no experience needed” and mean it.
- Keep the form short. Many applicants will be applying from a phone at another job.

Frequently asked questions
What does an HVAC apprentice do?
An HVAC apprentice works beside certified technicians on installs, service calls and maintenance visits while taking classes. Early duties include carrying equipment, running line sets and ductwork, mounting units and cleaning up. With experience they test circuits, check for leaks, braze joints, take readings and help diagnose faults, handling refrigerant only under close supervision until EPA 608 certified.
What are the main HVAC apprentice duties?
Assisting with installation of furnaces, air conditioners, heat pumps and ductwork; measuring, cutting and bending tubing; mounting equipment; helping with maintenance visits; testing electrical components; leak testing and brazing under supervision; stocking the van; recording time and materials; and attending related instruction.
Does an HVAC apprentice need EPA 608 certification?
Not to start. Under 40 CFR 82.161, apprentices are exempt from the technician certification requirement as long as they are closely and continually supervised by a certified technician during any work that could release refrigerant. Employers can have apprentices take the exam early, and the EPA says Section 608 credentials do not expire.
What are the EPA 608 certification types?
Type I covers servicing small appliances; Type II covers high- and very high-pressure appliances, except small appliances and motor vehicle air conditioning; Type III covers low-pressure appliances; and Universal covers all types. For Universal certification, the EPA requires the core section to be taken as a proctored exam.
How long is an HVAC apprenticeship?
BLS says HVAC apprenticeships last several years and combine paid on-the-job training with technical instruction each year. Registered programs follow 29 CFR 29.5, which requires at least 2,000 hours of on-the-job learning in total for a time-based program and recommends at least 144 hours of related instruction for each year.
How much do HVAC apprentices make?
BLS does not publish apprentice pay. HVACR mechanics and installers had a median wage of $29.33 an hour, or $61,010 a year, in May 2025, and the lowest 10 percent earned less than $40,050. Apprentices typically start near the lower end and move up a wage schedule as they progress.
What are good HVAC apprentice interview questions?
Ask what they have fixed or built, how they handle heat and cold, what they would tell a homeowner if the technician is not there, why refrigerant procedures matter, about a time they missed work, and where they want to be in three years. You are testing mechanical interest, reliability and judgment with customers.
What qualifications does an HVAC apprentice need?
Usually a high school diploma, a valid driver’s license, the ability to work in attics, crawl spaces and on roofs, and to lift and climb. No experience or certification is required for most apprentice roles. Some states and localities license HVAC technicians, so check your local rule for how apprentice hours count.
Is HVAC a growing trade?
Yes. BLS projects employment of HVACR mechanics and installers to grow 11 percent from 440,900 in 2025 to 489,100 in 2035, with about 40,600 openings a year. Training apprentices is a way to add technicians without bidding against competitors for experienced ones.
How much does it cost to recruit HVAC apprentices on social media?
Our benchmark does not separate apprentices. The technician and mechanic family, which we use for HVAC technicians, had a median cost per applicant of $13.41 on Meta in 2026, with the middle half between $7.40 and $23.58 and a 16 percent apply rate. Cost per applicant is not cost per hire.
