Becoming an experienced and successful HVAC technician means committing yourself to the occupation from day one. While classroom instruction from a highly rated HVAC school is a huge step in the right direction, there is no substitute for hands-on training in the field and one of the best ways to obtain this type of experience is through an apprenticeship.

In some states, an apprenticeship can act in place of an HVAC degree when it comes time to apply for a license. However, many states have a combined requirement for apprentice hours and classroom hours, so any prospective apprentice should be sure to review the requirements for their particular state before proceeding down a certain path.

HVAC apprentices may be able to find work with one of several different organizations. Some apprentices may work through a local union or may choose to find an independent technician that is willing to train them. Most HVAC apprenticeships last between three and five years, but again different states have requirements for how many years (usually measured in hours worked) an apprentice must work before becoming licensed and able to work on his or her own.

The following list includes a variety of HVAC apprenticeships across the country, including those programs that are offered through local colleges. These programs pair up new HVAC technicians who are eager to learn with experienced technicians who can teach them. With a variety of programs all around the country, there is likely to be a nearby HVAC apprenticeship somewhere on this list.

As you can see from this list, there are HVAC apprenticeship programs located in every corner of the country and there is no way this list could include all of them. Instead, we have culled available apprenticeships according to some basic criteria, which we outline below.

  1. State Approval - The US Department of Labor regulates apprenticeship programs throughout the country with a specific set of standards. The apprenticeships on this list all adhere to the US and local state requirements for an approved apprenticeship, which means they include a minimum number of on-the-job hours and classroom training activities.

  2. Geographic Variety - While there are generally more apprenticeship opportunities available in larger states, we wanted to be sure to include programs throughout the country. Most prospective apprentices will not be willing to uproot themselves for this type of opportunity so for the sake of usefulness, it was important to create a list with geographic variety apparent.

  3. Union Diversity - A number of the apprenticeship programs listed here are affiliated with local unions that maintain a Joint Apprentice Training Committee (JATC). While these programs are generally thorough and offer some of the best wages available, we wanted to be sure to also include those programs for which joining a union was not required.

The United States needs more skilled tradespeople, particularly in the HVAC workforce. Part of the reason is demographics: as the Baby Boomers retire, there are fewer Millennials and Zoomers to replace them, and the number of skilled trade jobs continues to outpace the supply of qualified workers to fill them. But that shortage is compounded by a historical cultural push towards students getting traditional, four-year liberal arts bachelor’s degrees, few of which are necessary for a successful career as a skilled tradesperson.
