Before a furnace breaks down completely, you must have noticed signs that signify that your equipment is malfunctioning. The following are the most common furnace issues that may point to something more pressing problems that can soon result in a damaged furnace or to something more dangerous scenario.

Undoubtedly, when you smell fuel in your house, it may be normal to panic. Everyone who smells fuel fear of an explosion, and that is not impossible to happen when there is a leaking furnace. While leaks may not always lead to an explosion, it can have some severe health implications. You can have carbon monoxide poisoning for all you know, which can make you unconscious.

You can truly get irritable when your furnace produces continuous disturbing sounds. While furnaces produce some sounds, a persistent loud and squealing noise signifies that there must be a problem with your heating device. The noise is usually caused by the fan or belt or some loose components.

The pilot light provides the flame that lights the gas coming out from the gas burner. The standard color of the flame is blue.
