Fixing a furnace is a lot of hard work, especially when the furnace keeps catching on fire! I have never seen anything like this furnace. It all started when I was called into an Heating, Ventilation, and A/C customer’s household on an emergency visit. Their Heating, Ventilation, and A/C customer said that their gas furnace was spitting flames out of it. I jumped into my heating and cooling van and rushed to the scene, hoping I had all of the heating and cooling device for sale that I would need. When I arrived at the household and was led to the furnace, I saw the strangest scene ever. The gas furnace had fire coming out of three or four bizarre spots,and it was making a unusual noise. The first thing I did was turn off the gas so that the gas furnace had nothing to feed the fire. After putting the fire out, I took care of the air ducts and gas lines for gas leaks, however found none. The gas furnace itself seemed perfectly fine, and I, a heating serviceman, had no idea what was wrong with the gas furnace. After doing all I knew to do, I left the house, still confused about the gas furnace, later that week, I was called in again for the same reason. This time I brought a fellow heating serviceman to see if she could help me find the issues with the gas furnace, once again, I saw the gas furnace with fire spitting out of it. My pal and I turned off the gas and took care of the air ducts and gas lines however found no leaks. The other heating serviceman was as frustrated as I was. To this afternoon my good friend and I don’t know what was wrong.
