Furnaces, especially older models, will tend to make some noise. Minor pops are some of the more normal sounds you tend to hear coming from a furnace. However, if the noises you are hearing are loud or uncommon, you may want to get your furnace checked out by a professional. Ignoring these sounds can lead to long-term problems that could end up costing you a fortune. Here are some specific noises that should never be overlooked.
A Loud Metal Scraping Sound
A loud scraping noise that sounds like metal is rubbing against other metals is something that needs a professional look! This sound usually indicates that something is terribly wrong with the furnace’s blower wheel. As soon as you hear this noise, it is imperative that you immediately turn off your furnace and call a professional as quickly as possible.
A Very Loud Pop Or Bang
As soon as you turn your furnace on, what do you hear? Is it a loud bang or pop? If so, you might have a severe problem on your hands. One common reason that your furnace is making this specific sound is that your furnace’s burners are dirty. Another reason could be that you have expanding and contracting air ducts. Homeowners with metal ducts will typically encounter this issues at least once. The ducts expand and contract as the furnace turns on and off. This sound could merely be a sign of undersized ducts, closed vents or a clogged air filter.
A Squealing Or Whining Noise
A high-pitched squealing noise should never be ignored. There are a few reasons that your furnace is making this particular sound. One reason could be that your blower belt is loose, slipping or possible even fraying. In essence, you’ll need to replace it immediately so that it doesn’t do any damage to your actual furnace. Sometimes, your furnace will make a whining noise when the shaft bearings need some more oil. This can really only be done by a professional technician. That is why it becomes so critical to contact your technician to examine the issue before it becomes severe.
