ASE Question Of the Month 
Sponsored By
Federated Auto Parts
Which is correct?

You’re correct if you answered C!

Refrigerants have unique service ports and specific RRR machine requirements, and the newer R1234yf gas is no different. Additionally, the R1234yf machine requires a refrigerant ID check prior to recovery. Good thing, too! The cost of R1234yf is significantly more than R134a and the last thing you want to do is contaminate your supply!
