The first guy from Southside Plumbing they sent out seemed to know what he was doing, but when my part came in, and the second guy came out - he first told me that he was told he just needed to replace the part. I informed him that I needed the gas line for the pilot line replaced and the igniter checked out, he informed me he had no paperwork from the initial service call. He cut the old tubing, that was leaking, and used it to make a shoddy line connection to the pilot and igniter, dumb me I assumed they would use a new piece of tubing. Then he had me come down and look to see that he was getting any kind of spark from the furnace or any kind of gas, and without the wiring diagram he couldn't figure out what the 24v line was, thought that was strange I can use a volt meter, but I don't get paid $120 an hour either. He told me he would have to go back to the shop, and they would be in touch. I waited several days and contacted them, they informed me that they technician says I need to buy a new furnace because mine is almost 30 years old. I was shocked, because the furnace had worked perfectly last winter and on the initial service call told everything looked good. So I went down turned on the power and the gas and set the thermostat, it lighted up perfectly and worked just like it always had. Then I assumed that maybe this technician didn't turn on the power or the gas when he showed me nothing was working, I told him when he came in they were both off and showed him how to turn them on. I was very angry at this point, because they were obviously trying to sell me a new furnace, so I called them back told them it was working fine and didn't appreciate the fact that the technician was obviously not aware how to work on a furnace or was trying to mislead me. I told them I still expected the pilot light gas line to be replaced properly, and the igniter still needed to be adjusted or replaced - they told me a technician would be in touch with me. I finally got in touch with the gentleman returning my call, I guess the owner, he asked me if I was certified to work on furnaces, I told him no, he said that means I don't know anything then and have no right to tell them how to do their job! He told me that he hires only the best technicians, I inquired how come he can't use a volt meter, or figure out how to turn the gas valve on. He told me that since they can't find a wiring diagram for my furnace, the manufacturer doesn't offer them anymore, and therefore it is unsafe to use and he will not guarantee any of the work done on it. He would replace the pilot gas line tubing on his dime, but any other work would be priced heavily and without any guarantee of my safety. That is what I call good customer service, you get caught trying to take advantage of someone, then belittle them for questioning it and threaten their safety. On the initial service call the technician checked all of the burners and the heat exchanger, he informed me that everything was in good working order, I only needed to replace the flame sensor and fix the leaking pilot line, and would have to wait and see if the igniter needed replacing or adjusting - then I went to an unsafe system with no guarantee of any work done on it, and all this for $600 - what a bargain?
