Steve was very knowledgeable. He diagnosed the problem and repaired it, all the while patiently answering my questions. My only concern with Bovio's service today was that they entered the time of my appointment incorrectly, and consequently I was in the house from 8:30 AM, when the technician was supposed to come, through 12 PM when the technician actually came, until 3:45 when the job was finished.
