HVAC Apprenticeship: 2025 Guide to Pay, Hours & Skills

Starting a career in heating, ventilation, and air conditioning (HVAC) is a smart move toward a stable, in demand job. For many, the best path forward is through an HVAC apprenticeship. This earn while you learn model is a powerful way to build a long lasting career without the heavy burden of student debt.

This guide breaks down everything you need to know, from what an HVAC apprenticeship is and how to apply, to the specific skills you’ll learn on the job.

What is an HVAC Apprenticeship? The Basics

At its core, a registered HVAC apprenticeship is a full time job that combines structured on the job training (OJT) with related classroom instruction. You get paid from day one. Once you complete the program, you earn a nationally recognized credential that proves your expertise.

Program Length and Training Hours

Most HVAC apprenticeship programs are built around a time based or competency based model. Time based programs typically require at least 2,000 hours of on the job learning, though most comprehensive programs last four to five years and involve around 8,000 OJT hours. Union programs might even require up to 10,000 hours to ensure complete mastery of the trade.

Related Classroom Instruction

Alongside your hands on work, you will also attend classes. Federal standards recommend a minimum of 144 hours of related instruction for each year of the apprenticeship. This classroom time covers the theoretical and technical knowledge that supports what you do in the field. This instruction can happen in a traditional classroom, at a community college, or even through approved online courses.

Getting Started: Your Path to an Apprenticeship

Ready to jump in? Here’s how the process generally works.

The Application Process

To start an HVAC apprenticeship, you typically apply directly to a program sponsor. A sponsor can be a single employer, a consortium of businesses, or a labor management committee like a local union. The sponsor is ultimately the one who decides who gets selected. You can find opportunities through resources like the official Apprenticeship Job Finder.

The selection process often includes:

• A formal application

• Checking documents like your high school diploma or GED

• An interview or aptitude test

• Meeting physical requirements or passing a drug screening

Common Eligibility Requirements

While each sponsor sets its own minimum qualifications, most programs require you to be at least 18 years old and have a high school diploma or equivalent. Some may also ask for prerequisites in math, such as algebra, or have you take a placement test to gauge your skills.

Continuous Enrollment and Finding a Sponsor

Some programs have specific intake periods once a year, while others use a continuous enrollment model, accepting applications year round and hiring as employers need new apprentices. To find programs, check the U.S. Department of Labor’s partner finder or your state’s apprenticeship agency website for lists of active sponsors and their contact information.

The Financials: Pay, Tuition, and Career Outlook

One of the biggest advantages of an HVAC apprenticeship is the financial structure. You avoid the massive debt often associated with traditional postsecondary education.

Starting Wage and Progression

Apprentices are paid employees from their first day. Programs must include a progressively increasing wage schedule that rewards you as your skills grow. While starting pay can’t be below the minimum wage, the outcomes are impressive. Roughly 91% of apprentices are employed after completion, with an average starting salary over $60,000 across all trades.

Tuition and Paid Instruction

While not required by federal regulations, many sponsors cover the cost of your classroom instruction, meaning you get a top tier education at little to no personal cost. This makes an apprenticeship an incredible value compared to the average tuition for a public two year college, which was over $4,000 for the 2025-2026 school year.

If a multi year HVAC apprenticeship feels like a big commitment, you can build a strong foundation first. SkillCat offers self paced courses that can help you learn the fundamentals and get certified on your own schedule.

A Look Inside the Program

What does daily life in an HVAC apprenticeship actually look like?

Weekly Schedule and Class Hours

A typical week involves working a full time 40 hour schedule on a job site with an employer. Your classroom training might be scheduled for one or two evenings per week. Some programs use a day release model, where you attend an eight hour class every week or two.

Union Apprenticeship Option

Union apprenticeships, often run by Joint Apprenticeship and Training Committees (JATCs), are a very common and structured pathway.

These programs are governed by collective bargaining agreements, which clearly define your wages, benefits, and scheduled pay increases as you progress.

Equal Opportunity Policy

All registered apprenticeship programs must adhere to strict equal opportunity policies. For inspiration and community, see these women in the trades. Sponsors are prohibited from discriminating based on race, color, religion, national origin, sex (including pregnancy and gender identity), sexual orientation, age (40 or older), genetic information, or disability.

Essential Certifications and Foundational Skills

Before you can master complex systems, you need a solid foundation. An HVAC apprenticeship curriculum is designed to build your skills from the ground up.

EPA 608 Certification Requirement

Under federal law, any technician who maintains, services, repairs, or disposes of equipment that could release refrigerants must be certified. This is known as the EPA Section 608 certification. While an apprentice may work on equipment under the direct and continuous supervision of a certified technician, you must get certified to perform these tasks independently.

Getting this credential early can make you a more attractive candidate. You can get your EPA 608 certification online with SkillCat’s approved, on demand courses and proctored exams.
