The consultation and review of our homes requirements and options were explained very well and done in a professional manner by Greg. Gary was very helpful and honest when discussing options and recommendations also. Daniel and Mike were very professional and cordial in the removal of the old system and installation of new system. The system works as advertised. Daniel and Mike explained the operation and details of the system to us prior to leaving and answered all questions very thoroughly and politely. They also fixed our gas insert remote which was greatly appreciated. We would highly recommend G&G.
