摘要：	For many, the Memorial Day weekend we'll celebrate later this month not only marks the end of winter, but it also heralds in another A/C service and repair season. And for the uninitiated, it may also present new challenges that will need to be overcome. For example, while the refrigerant known as R1234yf is not new, servicing these systems that are falling out of factory warranty may be new to you! Another challenge may be in deciding how to approach your troubleshoot- ing when dealing with even the most common customer concern-lack of cooling. With the advances in climate control systems and multizone comfort areas in the cabin, the answer may not be a system that is low on refrigerant but one that is not sending the incoming air where it needs to go.
