MACS A/C Temperature Testing

In order to determine variations in refrigerant charge, MACS’ Steven Schaeber walks you through measuring temperatures from the inlet to the outlet ports on various HVAC components so that A/C malfunctions can be determined. A wide range of related topics are included: identifying sealant and refrigerant; diagnostics for temperature drop, and pre-and post recovery; testing evaporator and condenser temperature, as well s coolant voltage. The tools to conduct temperature testing are also covered. Moreover, case studies on the orifice tube and expansion valve system are presented.
