I found this company through Homestars. They had a ten star rating as well more than 700 reviews. I figured I couldn't go wrong, and I was right! This company has an exceptional level of communication, respect and empathy for their clients. They did the little things that impress me. When providing me with a window of arrival, 2-4pm, they called at around 1pm letting me know the exact time of arrival so that I wouldn't have to wait around. Unfortunately, when they arrived, both compressors had malfunctioned as it was one of the coldest days ever recorded in Toronto (-37 degrees Celsius with the wind chill). Both technicians were incredibly apologetic and explained the situation to me. They said that Paul would be calling me shortly to reschedule. The situation was out of their control but they were still the first to offer me a further $100 off of my quoted (and emailed!) work order and sincerely apologized for the inconvenience. Costs were transparent and fair, the work was professional and the technicians were efficient, courteous and skilled. I will definitely be using this company again and would recommend them to anyone I know.
