In a forced air system, some furnace sound is common and to be expected. However when they hear uncommon bangs, pops, squeals or clicks, homeowners get worried – and with good reason! Certain furnace noises suggest certain problems. While some can be fixed throughout a routine maintenance visit, others are an early warning sign that your heating system is in need of more serious and probably costly fixings. How can you tell the difference? Begin with this simple guide:
Banging noises: In time, carbon can accumulate over the gas pipeline openings resulting in your furnace’s burner. This creates a very small pocket where natural gas can gather as long as the furnace is starting up. Whenever that gas pocket ignites, a bang is heard. Normal cleaning of the burner and the incoming gas jets will get rid of the concern and can be managed as part of a standard maintenance visit.
Popping sounds: House owners sometimes notice a popping or banging noise when their furnace is operating. In many cases, the sound originates in the ductwork and is caused by the growth and contraction of the sheet metal as air moves through it. Although distressing to some house owners, this kind of sound is generally part of a furnace’s typical operation.
Clicking sounds: A clicking noise is frequently created if the furnace’s flame indicator isn’t functioning correctly. This sensor is developed to inform the furnace when the gas has ignited and is correctly flowing to the burner. If dirty or corroded, the indicator will make a clicking sound. The solution? Have a licensed technician figure out no matter if a basic cleaning will be enough or if the indicator just needs to be replaced.
Squealing noises: Loose or worn blower belts produce a loud, squealing noise. Don’t delay – have them changed immediately to avoid serious issue to the furnace.
