New A/C Service Requirements - Are You Prepared to Cross the Threshold from the Unknown to the Known?

In your shop, you deal with knowns and unknowns every  day. While you might know what a  customer's complaining about when they drop off their car, you won't know the cause of that complaint until you investigate it further.
The upcoming changes to mobile air conditioning service regulations have their own set of knowns and unknowns.
Here's what we know:
-HFO-1234yf Refrigerant has been accepted by EPA as R-134a's successor.
-Cars are entering the vehicle fleet with HFO-1234yf.
-HFO-1234yf will be roughly 10 times as expensive as R-134a, at least initially.
-Unique fittings and labels will be required for the new refrigerant.
-New equipment will be required.
-Some revisions to the ASE Section 609 Refrigerant Program will be coming.
Here's what we don't know:
-The exact date when EPA will release its new requirements for air conditioning service.
-The scope of details that will impact the ASE Refrigerant Recovery and Recycling Program. This means things like content changes, and credentialing requirements.
-When you’ll be presented with your first HFO-1234yf service opportunity.
OK, so, you know change is on its way. Now, how can ASE help you cross the threshold from the unknown to the known?

The exact cost of the changeover is unknown, since the exact specifics have not been decided. Plus, the cost will be influenced by exactly what's needed in each shop. The exact EPA requirements for re-credentialing are still pending from EPA, so stay tuned for details. HFO-1234yf will only be made in larger containers; there will be no small containers for the DIY market. It will be illegal to retrofit R-134a systems to HFO-1234yf, so this latest refrigerant transition will not mimic the switch from R-12 to R-134a. Legalities notwithstanding, it wouldn't prove cost-effective to retrofit from R-134a to HFO-1234yf anyway, since it's estimated HFO-1234yf will initially cost 10 times as much as R-134a.

How much will this change cost? Are all technicians required to get re-certified for the 1234yf? Is the 1234yf going to be widely available for personal use, or is it just for dealerships to purchase? Will we have to change older systems to be compatable.

The 2013 Cadillac XTS and ATS will be introduced with HFO-1234yf refrigerant. Service procedures, credentialing, and equipment will all be affected. There are standards addressing these areas, but they need to be adopted by EPA and put into a final rule before ASE can advise you about the "final word" on all the details. The pressure/temperature relationships of R-134a and HFO-1234yf are very similar. Thanks for the questions and stay tuned.

When is this going to hit the new cars is it going to come out in 2013 or 2014

will there be certifications for this new system of ac service, or procedure. or is it just new revisions equipment etc ?

When will the new equipment be available for purchase? Such as, reclamation, recycling Also, gauges. Will the viscosity of the 1234yf be compatible to the curent 134A, Will techsbe required to have additional credentialing? The credentialing costs?
