About Course

Online HVAC Prep Course: Heating, Ventilation and Air Conditioning Basics

The Online HVAC Prep Course: Heating, Ventilation and Air Conditioning Basics is an online course dedicated to providing an introduction and overview of the principles of the refrigeration cycle and the mechanical components of an air conditioning system.

Initially, students learn about refrigerant safety and handling. The HVAC General Safety Practices online course gives specific information regarding which tools are safer to use and why. There is an abundance of screwdrivers, drills, electrical testers, saws, hummers, extension cords, hex-head screws and bolts, pliers, pipe ratchets, shears, crimpers, staple guns, refrigeration gauges available on the market. The instructor will go over safety features for the most used tools, give industry tips and inform of OSHA safety recommendation practices.

The Online Prep Course: Heating, Ventilation and Air Conditioning progress to a study of pressure, temperature, and basic thermodynamics.  In our Online HVAC Prep Course, the discussion of thermodynamics lays the foundation for understanding refrigeration systems,  the function of their components, variations of their design and as a result help you diagnose a problem in more systematic and effective manner, saving you time, money and effort. 

This will be followed by studying the refrigeration cycle and the components common to any refrigeration system.  Each component will be examined for their basic function and operation within the refrigeration cycle.  In this Online HVAC Prep Course, we discuss refrigerants, old and new, along with the certifications that may be needed to handle them. We pay attention to the different types of refrigerants: CFCs, HCFCs, and HFCs.Other components (accessories) that may be found in a refrigeration system will be discussed and explained and studied for their appearance and function within the system.

Finally, the Online HVAC Prep Course: Heating, Ventilation and Air Conditioning describes appropriate pressures and temperatures to be found within an HVAC system will be discussed and studied to ensure their proper operation.

About Teacher

Julio Herrera is the co-founder of AirCon Academy and an experienced vocational technical skills instructor for over 30 years.

In 1979 Julio enlisted in the US NAVY where he acquired necessary skills in maintaining and servicing various types of air conditioning systems, air handlers, chillers, hydraulics/pneumatics systems, pumps, and boilers.

After the Navy, Julio made a decision to continue his career as a building engineer with Washington Metropolitan Air Transit Authority (WMATA) where he developed a passion for teaching. He felt strongly about sharing and passing his knowledge to others and taught HVAC systems, Refrigeration, Electrical Motors, Schematics, Basic Electricity, and Heat Pumps, as well, as prep courses for CFC Universal and R410-A and other refrigerants to over 9,000 students during his teaching career.


Julio Herrera believes that the online technical skills training school without walls “AirCon Academy” will provide the opportunity to learn HVAC trade to everyone, any place, any time, on any device.


“I enjoy teaching and seeing how information and knowledge which I give to my students, changes their confidence at a work place, enhances careers, and improves their financial state. I am proud of my students who are now owners of HVAC companies, directors of building engineering, or just extraordinary HVAC professionals who can troubleshoot the equipment, fix it if needed, and suggest improvements to it’s maintenance”
