I was most impressed with the notice I got from Direct Energy advising me that I needed to book my maintenance appointment. As soon as I requested the service, I was given a time slot and date and your guy was there on time. He called to ensure I was ready for him and throughout the experience, he was very friendly and most knowledgeable. He explained things to me about the system and think I should check every year, Nobody has ever told me these things so now I have some idea of making sure I look after our investment. I wish I could remember the technicians name as he was just great and should be commended for his customer service... I was truly impressed. Thanks!
