Our home was hit hard by Toronto's recent blizzard with power surges knocking out our electrical system, various lights, and frying our furnace. Based on our previous excellent service from Convertible Heating and Air Conditioning, we contacted the company. Sean was not even on call that weekend, but because our furnace is in a crawl space and one of his colleagues has bad knees, he was "next man up." He was confronted with multiple issues over three days and late into the night because of his prior work schedule. First, he discovered that the furnace control board was rendered defective. When he tested its replacement, he found that the thermostat was also not functional. Finally, after replacing our thermostat, he found that the blower motor had burnt out. Having to go out of his way to find a new blower motor, he added it and a power choke to reach ultimate success. Perseverance and determination came through for us thanks to Sean's exceptional patience. He also did not charge for all the hours he put it. On top of that, he still takes his boots off when he's not working on the furnace. My wife and I were thrilled to have our heat back on thanks to his relentless efforts.
