HVAC System (Psychometric – Air Handling System – Duct Selection)

Hello! If you are starting out in the HVAC industry, or wished to gain more knowledge in an area which seems complicated and confusing to most people, you have found the right course!

My strength and approach in training is simplifying the important knowledge into something you will be able to grasp easily. In this course, I cover the air side in building air conditioning systems extensively, and will build your knowledge slowly until you reach the competency of evaluating, selecting and sizing Air Handling Units (AHU) and Air Ducts.

Join me to give yourself a head start in the HVAC career!
