The technician who came to my house, Joel S, was extremely helpful and courteous. He gave me a courtesy call prior to coming out which I appreciate. Once on site, he showed a lot of enthusiasm and showed he likes what he does and cares about his customers. He was very patient with my questions and he enjoyed educating me. He was very helpful in setting up my thermostat and at no point did he show he was in a hurry to leave to get to his next call or eat lunch. I will be requesting Joel S. the next time I require service.
