nhamparian in Toronto

I called Toronto Home Comfort twice within a 4 month period as I could smell gas from my fireplace. The first technician checked it out and reported all was well. ( $126.30) The smell persisted and I called once again to say the pilot light was now going out on its own (had never happened in the 7 years I have owned the fireplace) . A second technician came, changed a part going to the pilot. He assured me it was now in good working order. ($565.00) The smell persisted and I finally called Enbridge who came immediately, issued a tag and shut the gas off to the fireplace. The Toronto Home Comfort technician who came to address the TSSA tag told me that it was a manufacturer's defect and changed a part going to the pilot. (no charge) I have asked and not been given a clear explanation as to why the defect was not detected at the outset and why I was left at risk for 4 months.
