Free Online HVAC Courses

Becoming a HVAC Professional 

This all-rounder course covers psychrometric charts for optimum humidity, various HVAC systems, and how indoor ventilation works in buildings. An optional certificate is available.

Basics of Air Conditioning and Refrigeration Systems

In about three hours, this short free course can ground you in the basics of AC and cooling systems for indoor air quality in buildings, food storage and even water chillers.

As man-made climate change increases global temperatures every year, the need for qualified heating, ventilation and air conditioning designers, suppliers, installers and maintenance crews will only increase. 

Our free online courses make HVAC easier to study by breaking this extensive topic down into shorter modules with plenty of supporting diagrams, illustrations, videos, charts and graphs. This approach demystifies complex topics like HVAC even if you don’t have a science or engineering background. 

Our foundational courses are generally around two to three hours long: complete one over a morning or evening when your schedule allows. Once you know that this is the profession for you, you can specialise with longer courses of up to 30 hours of learning in marine climate control for ships or sustainable architecture.
