Freddy in Old Toronto

My gas furnace stopped working so I phoned Belyea Brothers from whom I originally purchased the furnace in 2000. I figured out myself what the problem was - the hot surface ignitor. They told me on the phone the cost of an evaluation ($130) plus parts, etc. They arrived within an hour and 15 minutes. So far, excellent. The speed of response was better than excellent. The repairman agreed with my diagnosis in about 2 minutes (cost, so far: $130). He then went to the truck and after a long phone call, presumably with his office, came back and told me had the part which would cost me just under $500. This is sort of blackmail and we both knew it. I had no heat in the house and had little option but to agree. He could have made up any number for the cost so i guess I'm lucky it wasn't even more. I checked on the web later and the part costs between $75 and $200 but he charged me $500. I would never use this company again.
