Sahli in Calgary

Mid Dec my 25 yr old furnace failed to ignite once/day randomly for a week. Found CHS in Homestars. Mohsin arrived on time. He confirmed the flame sensor (installed last winter) was good. He cleaned the burner in front of the spark generator and adjusted the gas pressure. At my request, he replaced the sparker with one I supplied. He was professional, accomodating and friendly. Price was resonable. Problem has not recurred since the service.
