This could be an indicator that there is an excess of carbon monoxide gas in the system and this could not only be dangerous but it can also be deadly
Heating with natural gas is one of the most economical ways to keep your house warm. In many cases electrical HVAC systems are far more costly to run due to the average price of this energy source. For this reason most homeowners, especially in regions where Winters are long, tend to choose natural gas as their fuel of choice. There is one issue that needs to be carefully monitored when heating with natural gas and that is the supply line for your furnace or boiler. With natural gas there needs to be a proper ratio of elements in order for it to burn efficiently and the pilot light is a good indicator as to whether this is happening. A normal pilot light should burn with a bluish colored flame and if it does then all things are operating properly in most cases. However, if your pilot light is a yellow color, you may want to have your system serviced right away. This could be an indicator that there is an excess of carbon monoxide gas in the system and this could not only be dangerous but it can also be deadly. Should you notice this problem you should more than likely shut down your furnace and call for a repair. Her monoxide is one of the most dangerous gasses and it can be present in your home without you ever knowing it. In most cases if the pilot light goes out your system will automatically shut down anyway but the likelihood of you knowing whether there is a carbon monoxide leak, unless you have a monitor in place, is slim to none.
