A/C systems are constantly being updated with new technology and service procedures. Find out if you’re up to speed on the latest in mobile A/C systems with this five question quiz.

Technician A states that the job of the A.C. compressor is  to act as a refrigerant pump. Technician B says it also raises the pressure and temperature of the refrigerant for greater heat transfer in the condenser. Who is correct?





Technician A states that the evaporator uses the cooling action of vaporizing refrigerant to cool the air inside the vehicle. Technician B says the most commonly used refrigerant in today’s vehicles is R-12. Who is correct?





Two technicians are discussing A.C. system operation. Technician A states that the refrigerant oil in the A.C. charge is there only to  reduce friction and wear in the compressor. Technician B says the oil is used to lubricate the parts of the A.C. system and is carried throughout the entire system. Who is correct?





Technician A states that A.C. uses 5% of all fuel burned by today’s motor vehicles. Technician B says that A.C. use only consumes about 2%  of all fuel burned. Who is correct?





Technician A states that design modifications such as solar powered roof ventilators and insulated head liners are being tested for use. Technician B says that infrared reflective glass as well as infrared reflective coated roofs are also being tested. Who is correct?

  1. The second question concerning the “cooling action” of “vaporizing” refrigerant. This is incorrect as refrigerant is vaporized by taking on latent heat to push it over from a liquid to a gas, therefore the statement is incorrect. It should read:

    “Technician A states that the evaporator is used to transfer heat thus vaporizing the refrigerant to cool the air inside the vehicle.”

    Thanks for the time and effort you put into your site.
