A professional, well coordinated team that doesn't take shortcuts.
McMaster installed a 2 tonne central air, 3 tonne central heating, air purifier and attic insulation in my 1930's home. They were confronted by challenges at every turn that required solutions that a seasoned professional would know that met local building code. They showed up promptly each day and worked quickly and as well coordinated team that managed to complete the install in 3 days in spite of the complications. I read many reviews on Carrier equipment and concluded that the install and comissioning of the system is at least as important as the choise of equipment. The installation is neat and as unobtrusive as possible. McMaster came highly recommended by a neighbor and friend and now i am happy to continue the recommendation.
