Sam was a referral from a plumber we use. Our mid-efficiency furnace crapped out on us and given it's age, it was time for a replacement. He installed a high efficiency unit that met our needs perfectly. The price, including installation, was right where I needed it to be (substantially less than the total cost of the mid efficiency furnace I had installed years earlier). He explained things thoroughly, with no surprises. On top of that he explained what he was doing, step by step, to my son who is attending Humber for their HVAC program. Would recommend Sam in a second.
