I was very satisfied with the job. Only time will tell how good the performance is. The installation crew DJ. Otis, and Jermaine where very polite,courteous,and Knowledgeable.My experience with the office staff and my salesman David Hogg was very good. I was also satisfied with the cleanup that the crew did. My salesman David was very knowledgeable. The installers worked under horrible heat index of 107 but never complained. They deserve some recognition or bonus.
