“I was really impressed by the level of professionalism shown by your service technician.  He was well dressed  and was wearing  a company shirt.  He showed up in the coolest AC van I’ve ever seen.  Nice graphics.  And, he did an excellent job of explaining everything to me before starting the repair.  When he was done, he cleaned up and my problem was solved.  Thanks, Econo Air.  I will recommend you to my friends.”
