Terrible communication and never followed through with their commitments. They initially provided great and advice and responses right up to the point of paying a deposit and trying to book in install. From then on they were impossible to communicate with to book in an install date. Following install we had problems with one of the components in our system and over 3 months on, Energy Assist still wont come out to fix the problem. Would never recommend or use these guys again. Once your money is paid, forget about getting any customer service again.
