It may indicate the presence of carbon monoxide if your furnace’s flame is yellow rather than blue. Our heating replacement technicians in Ardmore, OK, advise that any color other than blue in the furnace flame can signify incomplete combustion and a potentially dangerous issue, such as gas or carbon monoxide leaks.
Our heat pump repair experts in Ardmore say that carbon monoxide, a poisonous gas, is generated every time fuel is burned. The following are some indications that your furnace is emitting carbon monoxide:
- Absence of an upward draft in the chimney, and soot streaks around the furnace.
- Rust on flue pipes or other pipe connections seen on windows, walls, or other cold surfaces.
Leave your home and call your utility company to cut off your gas if your furnace emits carbon monoxide.
