Johnson County Community College – HVAC Technician Program

Program Information

The HVAC Technician program at Johnson County Community College is built for students who want a deep, system-level understanding of heating, ventilation, air conditioning, and refrigeration rather than a short-term overview. The program takes a methodical approach, combining classroom instruction with extensive lab work so students learn how HVAC systems operate, interact, and fail under real conditions.

Students are trained across the full range of HVAC functions, from installation and start-up to diagnostics and repair. Rather than focusing on memorization, the program emphasizes how to evaluate system performance, identify root causes of problems, and apply safe, code-compliant solutions.

Core areas of instruction typically include:

• Residential and light commercial HVAC system design
• Electrical fundamentals for HVAC equipment
• Refrigeration cycles, refrigerant handling, and recovery procedures
• Airflow, duct design, and ventilation principles
• Gas, electric, and heat pump systems

Lab-based training plays a central role in the program. Students work with industry-standard equipment in controlled settings, allowing them to practice system assembly, testing, and troubleshooting without the pressure of live job sites. This repeated hands-on exposure helps students build confidence working with tools, meters, and diagnostic equipment.

Beyond core mechanical skills, the program introduces students to modern efficiency and sustainability considerations. Coursework may address:

• Energy-efficient HVAC system design
• Load calculations and system sizing
• Green building concepts and indoor air quality
• Preventative maintenance strategies

Students also develop practical job-readiness skills such as reading blueprints, interpreting technical documentation, and following safety protocols required in both residential and commercial environments.

Program Length

The HVAC Technician program is typically completed over two years. Both full-time and part-time attendance options are available, making the program accessible to students balancing work or other responsibilities. The extended timeline allows for deeper technical coverage and more lab repetition than shorter certificate programs.

Program Requirements

• High school diploma or GED
• Basic math and reading comprehension skills
• Ability to lift equipment and work in varied physical environments
• Willingness to follow safety procedures and technical instructions

Graduates of the program are typically prepared to pursue industry certifications, including EPA refrigerant credentials, and to enter entry-level HVAC technician roles with a strong technical foundation. The program is often a good fit for students who want long-term advancement potential and a solid understanding of HVAC systems before entering the field.

Johnson County Community College’s HVAC Technician program is commonly chosen by students seeking structured training, extensive hands-on lab experience, and a comprehensive approach to HVAC technology.
