The TE Techs are very well trained knowledgeable. Prior to TE Certified I had 6 service calls for the same issue days apart via home warranty with 2 different companies. Neither company could accurately diagnose the problem. In one visit the tech accurately diagnose the problem, showed photo evidence of the problem and provide options. The tech explained all the options in detail. He provided me with enough information to make an informed decision. The estimated repair cost was market average. They honor returning clients with a discount.
