I was referred to Mike Li by my neighbor, who had done a fair of shopping around and was most impressed with Mike's price point and level of service for a furnace and hot water tank he bought from the Furnace Room. So I got Mike in for an estimate, he was very punctual, he illustrated well on paper the various options, rebates, etc. which impressed me. After Mike left, I still did my homework and got a few estimates but eventually decided to go with Mike for the following reasons: Professionalism, Punctuality, Good Advice, Good Product (Trane Furnace) recommendations, his efficient network of other trades people (energy auditor, duct cleaners, etc.) and good after sales service. All the best to Mike, the staff at the furnace room and the readers of this review!
