Program Overview

Collins Career Technical Center in Ohio offers a Heating and Air program for high school students interested in exploring careers in the heating, ventilation, and air conditioning (HVAC) industry. The program covers various aspects of HVAC systems, including refrigeration, electrical systems, and HVAC installation and maintenance. Students will learn about the fundamentals of HVAC technology, such as principles of thermodynamics, and how to use industry-standard tools and equipment. This program offers hands-on training and allows students to gain experience in the HVAC industry. The Heating and Air program is a two-year program for high school juniors and seniors. Upon completing the program, students will have the skills and knowledge necessary to pursue careers in the HVAC industry, such as HVAC technician or installer, or continue their education in a related field. According to the Bureau of Labor Statistics (BLS), job growth for HVAC technicians and installers is projected to be much faster than average for all occupations. The median annual wage for HVAC technicians was $48,630 in May 2021.

What do HVAC Technicians Do?

Heating, air conditioning, and refrigeration mechanics and installers typically do the following:

  • Install, clean, and maintain HVACR systems
  • Install electrical components and wiring
  • Inspect and test HVACR systems and components
  • Discuss system malfunctions with customers
  • Repair or replace worn or defective parts
  • Recommend maintenance to improve system performance
  • Keep records of work performed

Heating and air conditioning systems control the temperature, humidity, and overall air quality in homes, businesses, and other buildings. By providing a climate-controlled environment, refrigeration systems make it possible to store and transport food, medicine, and other perishable items.

Some HVACR technicians specialize in one or more specific aspects of HVACR, such as radiant heating systems, solar panels, testing and balancing, or commercial refrigeration.

When installing or repairing air conditioning and refrigeration systems, technicians must follow government regulations regarding the conservation, recovery, and recycling of refrigerants. The regulations include those concerning the proper handling and disposal of fluids and pressurized gases.

Some HVACR technicians sell service contracts to their clients, providing periodic maintenance of heating and cooling systems. The service usually includes inspecting the system, cleaning ducts, replacing filters, and checking refrigerant levels.

Careers in this Field

Here are some career fields that students interested in HVAC (heating, ventilation, and air conditioning) may pursue:

  • HVAC Technician: HVAC technicians install, maintain, and repair heating, ventilation, and air conditioning systems in residential and commercial buildings.
  • HVAC Engineer: HVAC engineers design, develop, and test HVAC systems and equipment, including heating systems, air conditioning units, and ventilation systems.
  • Energy Auditor: Energy auditors assess the energy efficiency of buildings and recommend improvements, such as upgrading HVAC systems or adding insulation.
  • HVAC Sales Representative: HVAC sales representatives sell HVAC systems and equipment to customers, including residential and commercial clients.
  • HVAC Project Manager: HVAC project managers oversee the planning, budgeting, and execution of HVAC projects, such as the installation of new HVAC systems in buildings.
  • Building Automation Specialist: Building automation specialists design, install, and maintain building automation systems, which control HVAC systems, lighting, and other building systems.
  • HVAC Instructor: HVAC instructors teach students about the principles and practices of HVAC systems and equipment.
  • HVAC Controls Technician: HVAC controls technicians install, maintain, and repair the electrical and electronic components of HVAC systems, such as thermostats, sensors, and controllers.

These are just a few examples of career fields related to HVAC. The field is constantly evolving, and new career paths may emerge as technology advances.
