I brought in MAS approximately 2 years ago for as the main Repair and Maintenance company here at Oracle Arena. I was looking for a new company based on the lack of service the location was receiving. I am very pleased with the decision to switch to them as the service we have received has been absolutely top notch every step of the way. MAS is incredibly quick to respond when service is needed and they send you email updates letting you know the name of the tech coming for service and the time he left. The technicians are all quite knowledgeable about the work they are doing and go out of their way to explain everything to me so I understand it. I would personally recommend MAS to others as we are very happy with them from both a service standpoint and the quality of work they do for us.
