“We understand the value of NATE certification in terms of quality service and customer satisfaction, and we require it of all of our technicians.  Every technician we hire must already be NATE-certified or must become certified within three months of joining our team.  By letting our customers know that we’re 100% NATE-certified, we’re assuring them that they’ll always be working with a technician who has proven to have what it takes to get the job done right.”
