What are the different types of HVAC licenses?

There are three types of Connecticut HVAC licenses: Apprentice, Journeyperson, and Contractor. Both the Journeyperson and Contractor licenses include ten separate specialty licenses.

Apprentice

Apprentice HVAC technicians enroll in a 4-year course, beginning with an S-2 qualification. The course is 720 hours of instruction and 8,000 hours of on-the-job training. You must obtain a permit from the Connecticut DCP and register with the Connecticut Office of Apprenticeship Training. Apprentices can work only under the supervision of a licensed contractor or journeyperson.

Journeyperson

To reach journeyperson status, an applicant must first complete a registered apprenticeship program and then pass a licensing exam. A journeyperson can only work under a licensed HVAC contractor. A journeyperson can obtain two types of licenses:

• Limited: Allows the licensee to work in a specific area of the industry
• Unlimited: Allows the licensee to work in any area of the trade.

Specialty licenses available for Connecticut HVAC Journeypersons are as follows:

• S-2 Unlimited Heating, Piping, and Cooling Journeyperson
• S-4 Limited Heating, Cooling, and Piping Journeyperson

Information detailing the scope of work and requirements for each of these licenses is maintained by the Connecticut Department of Consumer Protection.

Contractor

To become a contractor, a person must have worked for two years as an HVAC Journeyperson. As a licensed contractor, the HVAC technician can offer his or her services to the general public and employ journeypersons as well as apprentices. Services offered may include installing, repairing, and maintaining heating, piping, cooling, and sheet metal systems. 

In Connecticut, there are two official contractor licenses: Limited and Unlimited. A Limited license allows the contractor to work in a specific area of the trade, while an Unlimited license allows the contractor to operate in any area of HVAC. A contractor must pass a trade exam as well as a business and law exam.

Benefits of getting a Connecticut HVAC license

Obtaining advanced certification in the HVAC industry will give you room to further your career, increase your earnings, and develop your skills. Apprentice HVAC technicians can land a job and start earning money after only a few months, and they can grow their expertise while they work toward more advanced licenses. 

Working in the HVAC industry will also give you the opportunity to stay active. Where many careers require a significant amount of time spent at a desk or in an office, HVAC technicians move to a number of different job sites and work outside. An active career conveys health benefits like better physical condition, lowered risk of heart disease, and lowered risk of type 2 diabetes.

Average salaries for HVAC professionals in Connecticut

Hourly wages in Connecticut range from $21.44 to $48.78 per hour, although most techs, mechanics, and journeymen earn close to the state average of $32.34 per hour. A few things affect your wage: where you live (higher cost-of-living cities tend to pay more), your licenses and certification, experience, and education all factor in. As an hourly employee, you may be able to earn overtime, if you work over 40 hours per week, or receive a pay increase for working nights or weekends, for emergency calls. 

Salaried HVAC supervisors (such as an HVAC manager, field foreman, or supervisor) earn an average of $98,171 per year, with a range of $73,385 to $131,327. If you earn bonuses, that could affect your salary, as can your experience and education. If you own your own HVAC contractor business, you could make considerably more, especially as your business grows.
