COURSE overview

In our Air Conditioning & Heat Pumps Course, complex mechanical systems are broken down into simple components. Starting with basic principles of operation and building on an understanding, considerable detail is provided on how these systems fail.

Upon completion, students can inspect air conditioning and heat pump systems as a professional home inspector.

Within each section are several Study Sessions to guide you through the material. The Quick Quizzes will help you check your progress.
