Reviews
What customers say
Installation feedback is positive about the crews: one customer called the technicians friendly and experienced, while another praised the installers and noted a moving blanket used to protect the floor. One customer found the three-week installation wait longer than desired. In a separate service account, a heat-pump noise problem took time to resolve, but the team stayed involved until it was fixed.
Customer Reviews
larry cousens
Technician's were very good at installing my two units. They both were friendly and experienced. The wait time for installation was three weeks, would like to have had them sooner. Overall A+.
Gaetan Caron
We had a noise problem with the heat pump inside the house. The service was impeccable; even though it took some time, they never left us with the problem and resolved it perfectly. I highly recommend this company.
Marc Andre
I had an excellent experience with GNR, especially with Joël who gave me a great price thanks to the Logis Vert grant; I got a top-of-the-line machine for half price. I have nothing but praise for the installers too; they even took the time to put a moving blanket on the floor to protect it.
