The introduction of HFO-1234yf refrigerant in some models this year will generate a ripple effect into the entire landscape of A/C service. The Cadillac XTS will be the first car in the U.S. with a factory fill of HFO-1234yf. Others will gradually enter the vehicle fleet as manufacturers make the transition to this new refrigerant. Working on these systems will be governed by new regulations due later in 2012, when pending revisions from EPA for Section 609 programs will address servicing vehicles with HFO-1234yf systems.

Unlike the change from R-12 to R-134a, it’s illegal to retrofit R-134a systems to HFO-1234yf.  In fact, the two refrigerants should never be mixed, no matter the scenario. For this reason, systems using HFO-1234yf will use different service fittings. The stage is set to bring challenge and change to your air conditioning service practices--and ASE will be there to help you meet the challenge with an updated Section 609 Certification Program.

We're waiting to hear from EPA what their requirements will be going forward. Stay tuned.
