Luke was the technician. I appreciated that he called to let me know when he was arriving. He came prepared with the equipment to diagnose the problem with the generator. After careful examination, he determined what was creating the loud noise when the machine shut down. Unfortunately, he was not able to remedy the problem. He assured me that he would consult Kevin and find a way to find a remedy. He was able to update the software so that the machine would power down more slowly and thus reduce the noise level. He was knowledgeable, professional and very courteous. He answered all questions respectfully. He is a credit to the company.
