I was favorably impressed with G&M from the first phone call until the final installation. I very much appreciated the fact that everyone connected with the company spent time answering my questions and helping me to decide what kind of unit I needed. They were always timely returning my phone calls and on time for appointments. Overall, they did an excellent job and I couldn't have asked for better. I have recommended G&M to friends and neighbors and shared information with them to use in the future if and when they need service.
