Honest evaluation

Daniel was great and I plan to have him return. He did as much as he could since my system was frozen and all that he was able to do was evaluate and recommend. He could have snowed me and stayed longer and charged me for things he would not have done and I would not have been any wiser about. I appreciate honesty in service people. I will have him back and complete my service.
