Career Pathway Outlook Overview The Heating, Ventilation, and Air Conditioning Refrigeration (HVACR) pathway covers occupations related to systems that control the temperature and air quality in buildings, climatecontrolled environments, and refrigeration systems enabling storage and transportation of goods and services. In this secondary program, students can earn the NCCER HVACR Level 1 certification, which will give students a head start on obtaining industry-recognized credentials and better prepare them for a post-secondary HVACR program. The growing number of sophisticated climate-control systems is expected to increase the demand for qualified HVACR technicians. This pathway focuses on the following: installing, cleaning, and maintaining systems; installing electrical components and wiring; inspecting and testing systems and components; using communication skills to discuss system malfunctions; repairing or replacing worn or defective parts; maintaining systems to improve performance; and keeping records of work performed. In addition to technical skills, good listening, speaking, time management, and critical thinking skills can contribute to success in this occupation. HVACR professionals work in various settings, such as in homes, schools, stores, hospitals, office buildings, or factories. Some technicians are assigned to specific job sites at the beginning of each day, and others travel to several locations to make service calls. The top four industries with the highest levels of employment for HVACR mechanics and installers are building equipment contractors (namely, plumbing, heating, and air-conditioning contractors), direct selling establishments, commercial and industrial machinery and equipment, and personal and household goods repair and maintenance. In addition, the natural gas distribution sector is among the highest-paying industries for this occupation. The U.S. Environmental Protection Agency (EPA) requires all HVACR technicians who buy, handle, or work with refrigerants to be EPA 608–certified in proper refrigerant handling. Many trade schools, unions, and employer associations offer training programs to prepare students for the EPA certification exam. Most professionals in heating, ventilation, and air conditioning receive postsecondary instruction from technical and trade schools or community colleges that offer programs in HVACR. These programs generally last six months to two years and lead to a certificate or an associate degree. Success in this field requires continuous education to stay current with the latest equipment and skills. High school students interested in becoming an HVACR technician should take CTE, math, and physics courses. For example, careers with the highest earning potential—HVACR mechanical engineers or postsecondary teachers—require advanced degrees. An HVACR engineer is a mechanical engineer who designs ventilation, air-conditioning, and heating systems for buildings such as offices, schools, or residential spaces. HVACR engineers are usually professionals with previous expertise in plumbing and electricity, which helps them understand climate control systems. They know how air flows through different structures and can calculate heat load and loss. They collaborate with other construction specialists and follow local, state, and federal regulations and building codes. Needs of the Future Workforce According to the U.S. Bureau of Labor Statistics, employment of HVACR mechanics and installers is projected to grow 5% from 2021 to 2031. Also, on average, about 40,100 openings

13

for HVACR mechanics and installers are projected each year over this decade. Commercial and residential building construction is expected to drive employment growth. In Mississippi, the average employment growth total from 2020 to 2030, is projected to increase by 9.5% for all general occupations combined. The data given in Table 1.1 below, including the average hourly earnings, was compiled from the Mississippi Department of Employment Security in 2022. Table 1.1: Current and Projected Occupation Report Description Jobs, Projected Change Change Average Hourly 2020 Jobs, 2030 (Number) (Percent) Earnings, 2022 Control and Valve 480 500 20 $22.90 4.2% Installers and Repairers Cooling and Freezing 190 240 50 26.3% $17.60 Equipment Operators General and Operations 19,310 20,980 1,670 8.6% $40.72 Managers Heating, Air 2,650 2,930 280 10.6% $20.52 Conditioning, and Refrigeration Mechanics and Installers Helpers—Installation, 710 750 40 5.6% $14.88 Maintenance, and Repair Workers Installation, 1,140 1,200 60 5.3% $21.53 Maintenance, and Repair Workers, All Other Mechanical (HVAC) 1,590 1,710 120 7.5% $40.66 Engineers Plumbers, Pipefitters, 3,050 3,300 250 8.2% $22.80 and Steamfitters Source: Mississippi Department of Employment Security; mdes.ms.gov (2022). Perkins V Requirements and Academic Infusion The HVACR curriculum meets Perkins V requirements of introducing students to and preparing them for high-skill, high-wage occupations in HVACR fields. It also offers students a program of study, including both secondary and postsecondary courses, that will further prepare them for HVACR careers. Additionally, this curriculum is integrated with academic college- and careerreadiness standards. Lastly, the curriculum focuses on ongoing and meaningful professional development for teachers, as well as relationships with industry. Transition to Postsecondary Education The latest articulation information for secondary to postsecondary can be found at the Mississippi Community College Board website, mccb.edu.

Best Practices Innovative Instructional Technologies Classrooms should be equipped with tools that will teach today’s digital learners through applicable and modern practices. The HVACR educator’s goal should be to include teaching strategies that incorporate current technology. To make use of the latest online communication tools—wikis, blogs, podcasts, and social media platforms, for example—the classroom teacher is encouraged to use a learning management system that introduces students to education in an online environment and places more of the responsibility of learning on the student. Differentiated Instruction Students learn in a variety of ways, and numerous factors—students’ background, emotional health, and circumstances—create unique learners. By providing various teaching and assessment strategies, students with various learning preferences can have more opportunities to succeed. CTE Student Organizations Teachers should investigate opportunities to sponsor a student organization. There are several here in Mississippi that can foster the types of learning expected from the HVACR curriculum. SkillsUSA is an example of a student organization with many outlets for HVACR. Student organizations provide participants and members with growth opportunities and competitive events. They also open doors to the world of HVACR careers and scholarship opportunities. Cooperative Learning Cooperative learning can help students understand topics when independent learning cannot. Therefore, you will see several opportunities in the HVACR curriculum for group work. To function in today’s workforce, students need to be able to work collaboratively with others and solve problems without excessive conflict. The HVACR curriculum provides opportunities for students to work together and help each other complete complex tasks. There are many field experiences within the HVACR curriculum that allow and encourage collaboration with professionals currently in the HVACR field. Work-Based Learning Work-based learning is an extension of understanding competencies taught in the HVACR classroom. This curriculum is designed in a way that necessitates active involvement by the students in the community around them and the global environment. These real-world connections and applications link all types of students to knowledge, skills, and professional dispositions. Work-based learning should encompass ongoing and increasingly more complex involvement with local companies and HVACR industry professionals. Thus, supervised collaboration and immersion into the HVACR industry around the students are keys to students’ success, knowledge, and skills development.
