In this first course of the instructional program, students are taught to professionally install, repair, and maintain the operating conditions of heating, ventilation, air-conditioning, and refrigeration (HVACR) systems. Students work with piping and tubing, study the principles of heat and electricity, install duct systems, and comply with U.S. Environmental Protection Agency (EPA) regulations. Successful completion of the two-course sequence may prepare students for a career as an HVACR technician. Contextual instruction and student participation in co-curricular career and technical student organization (CTSO) activities will develop leadership, interpersonal, and career skills. High-quality work-based learning (HQWBL) will provide experiential learning opportunities related to students' career goals and/or interests, integrated with instruction, and performed in partnership with local businesses and organizations.


Legislation enacted in the 2015 Virginia General Assembly (HB1616) requires each sequence of courses constituting a career and technical education (CTE) program completion to be aligned with state or national program certification and accreditation standards, if such standards exist. To comply with this requirement all Heating, Ventilation, Air Conditioning, and Refrigeration programs must be accredited by HVAC Excellence.
