Covered is a history of HVAC systems, airflow throughout the system, the principles of refrigerant, diagnosis of common faults in older systems, testing procedures, and finally repair and, in the case of AC, recharging your system.

Components such as compressors, condensers, evaporator and heater cores, pressure switches, and climate control electrics and switches are also covered.
