Earl Diaz made quite an impression on my wife and me. He was very knowledgeable about the equipment and financing programs, and when our unit was proving to be more difficult to repair than usual Earl spent the time he needed (on his hands and knees out in the heat) to do the job right. Our house became very warm and we were uncomfortable, but because of Earl's persistence we're now cool and comfortable again. Alaska Air has a great representative in Earl.
