This course is a presentation of the Laws of the Thermodynamics of Heat, which are associated in the design and engineering of heating and air conditioning equipment. A well-founded understanding of such fundamentals is critical for valid functioning assessments of air conditioning and heating equipment during home inspections. Home inspectors will also be provided with minimal-time, uncomplicated procedural techniques of evaluating HVAC equipment performance so as to increase confidence when professional judgments are made as to whether HVAC systems are “just working or working properly.”
