What Do You Learn in an HVAC Trade School?

Ready to become an HVAC technician but still deciding on the right trade school? Different HVAC programs will offer different curricula. However, Ohio Business College (OBC) not only offers a complete curriculum, but we also provide real world scenarios for you to get plenty of hands-on experience. So, let’s start by looking at what HVAC is and what an HVAC technician does.

What is HVAC/R?

HVAC/R stands for heating, ventilation, air conditioning, and refrigeration. The professionals that work to maintain these systems are referred to as HVAC/R technicians. HVAC systems are segmented by the residential and commercial monikers, the main difference being the large size and complexity of the commercial HVAC systems.


A heating unit warms the air naturally entering into a home or commercial setting. Heating units can use gas, heating oil, or electricity. They must be regularly serviced and maintained. This requires an HVAC technician to set appointments on a regular basis to ensure that filters are replaced, and other critical components are still working properly.


Without proper ventilation, the air will quickly become unhealthy to breathe. HVAC technicians work to ensure that all structures are properly ventilated, and air quality is at healthy levels.

Air Conditioning

Air conditioners operate when the outdoor temperatures are exceeding a comfortable temperature during the summer months. Air conditioners are serviced in the spring, right before they are typically used in the summer. A/C units require periodic filter changes and other refrigerant fluid refills.


Many commercial businesses utilize refrigeration units to keep food and merchandise at a cool temperature. Beverages need to be chilled and ready to consume, medications need to stay at a stable temperature or cool temperatures must keep bacteria from contaminating food. These means refrigeration systems must be maintained regularly by HVAC/R technicians.

What Does an HVAC/R Technician Do?

An HVAC/R technician maintains, repairs, and installs HVAC/R systems. As an HVAC/R technician, you will work with complex mechanical equipment and HVAC/R components. According to the U.S. Bureau of Labor Statistics, heating, air conditioning, and refrigeration mechanics and installers typically do the following:

  • Install, diagnose, troubleshoot, and maintain HVAC/R systems.
  • Install electrical components and wiring.
  • Inspect and repair HVAC/R systems and components.
  • Educate customers on proper HVAC/R care and maintenance.
  • Repair or replace parts for different HVAC/R brands.
  • Recommend maintenance to improve system performance.
  • Keep records for future appointments.
