I'm in an on-going fight with my gas company. All my appliances are gas (water heater, range, furnace). My gas usage had doubled from the previous year, for no reason, so I asked the gas company to check on it, they changed the meter at my house and sent it out for testing. It wasn't long after that when I noticed that there were yellow flames with little to no blue on all my appliances. This is especially noticable when the furnace is running. I have had the appliances serviced, the gas company told me to call 911 to have the fire department check for CO in the house, there was none, the gas man finally came out to the house and told me he had never seen anything like this before. He changed the meter again and checked the pressure at the furnace, everything checks out. He told us we just needed to adjust the air mix in the furnace, we called the heater service man back out, he checked everything again and said the furnace was fine, there was nothing to adjust. I am at my wits end. Everything I read online says not to use gas appliances when they have a yellow flame, but then I won't be able to cook, shower or heat my home and it's 20 degrees outside already. Both the fire department and the appliance service people say it's the gas or something in the gas lines (i.e. rust got knocked around when the gas company changed the meter, etc.), but the gas company keeps trying to blame my appliances. I'm to the point where I'm considering purchasing a new gas range, because that's the least expensive and the easiest to change out just to prove someone wrong. Please help.
