Description
Technical instructor and HVAC expert Jerry Clemons completely covers both air-conditioning as well as heating systems, so you can save money repairing your own vehicle.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 air conditioning, recharging your system. Also included is proper evacuation and disposal of any residual refrigerant in the system. Components such as compressors, condensers, evaporators and heater cores, pressure switches and climate control electrics and switches are also covered. Finally, for people with older cars, converting from the no-longer-available R-12 to R134a is detailed.Automotive climate controls are a complex system and are difficult to repair without proper instruction.
