What noises are normal for a furnace?
Normal noises for a furnace can be a range of sounds, depending on the type of furnace and age of the system. Generally, the following sounds and noises should be expected from a working furnace:
•Gurgling, popping or boiling noises are caused by the formation and release of air and sediment in the heat exchanger when it begins to heat, which is normal.
•The sound of the gas igniting is the most common sound associated with a furnace, and can sometimes include a light “thunk” when the gas ignites.
•A blower motor sound is normal for furnaces that use a fan to push air through the duct work into the living spaces of the house. This is typically a whirring or clicking sound that may be heard throughout the home as the fan starts up and runs.
•Light thumping or humming sounds are expected as the blower turns on and off when the furnace cycles.
•The furnace may also make a vibrating sound if the blower or fan is running too fast. This should be diagnosed as quickly as possible and is a warning of a potentially serious issue, such as too much air flow.
Overall, if you hear a consistent noise coming from your furnace, it is always best to have it checked out by a professional to ensure it is in proper working order.
When should I worry about my furnace noise?
Generally, furnace noise is not indicative of an important operational issue. However, if you begin to hear loud, persistent noises coming from your furnace, you should contact a professional.
