Someone told me the other day that drivers should always turn off their car or truck's A/C BEFORE shutting down its engine. He said that this would lead to longer compressor life. I had never heard of this before and was wondering if this is even true. Anyone out there know of a good reason 'why' turning off an automobile's A/C compressor just before shutting off its engine would make it last longer? I couldn't think of a good reason myself. Now I CAN understand how not running the compressor very much at all would lengthen its lifecycle. That's obvious there.
Thanks in advance for any A/C-related expert advice.
