No complaints whatsoever. The office staff was professional, had good communication skills, and generally easy to work with. They even were able to schedule a same-day after hours appointment. Our technician, Justin, arrived on time (a bit early, actually), quickly repaired our broken condenser, and saved us from two weeks of roasting in our own house.

I would definitely use McMaster again, but hopefully I won't have to do so in the near future (crosses fingers). This was probably one of my best experiences with a contractor.

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.
