David Hernandez was one of the kindest, most patient and professional individuals I have had the pleasure to contact for service. He reviewed my situation in depth and patiently explained the issues that I didn’t understand. He NEVER pressured me about anything. He wanted me to be sure that the $4,500 service was right for me. In the end, I agreed and now my tenant and I are very pleased! I even requested David to be the technician at my Irvine house on 12/28, which your office staff kindly arranged. I have heard your radio adds for more than 15 years and I have always wanted to try your service. I am now a customer for life thanks to David! Happy New Year!! Cynthia Belmonte
