Furnaces are notorious for making unusual noises. When the furnace is running, you may hear tiny little pops or buzzes. When your furnace becomes louder than usual, or you hear a sound you’ve never heard before, it’s usually a sign of a problem with it, and it’s best to speak with your furnace specialist about routine maintenance work. You can also contact professionals for maintenance or furnace repair in Thornton, CO, to get your unit looked at.

What are Some Strange Noises Your Furnace Makes? 

While some sounds that a furnace makes are normal and should not be worried about, others indicate a severe problem. Mentioned below are three sounds a heating system produces and what they mean – 

  • Grinding Noises

If your heating system begins to make scraping noises, particularly the sound of metal scraping metal, something must be loose and must be repaired right away. 

Your air compressor wheel is most likely malfunctioning. Your furnace will not be able to heat your house if the exhaust motor is damaged. Any issues with your blower wheel should be addressed by a professional.

  • Banging or Popping Sounds

When dirt builds up on the furnace heaters, it can lead to a gas accumulation. When this happens, you will hear the loud pop or thump when the burners finally light up. 

This series of pops can cause damage to your boiler and fracture your heating system, requiring costly repairs. Hence if you hear this kind of noise, it’s a good idea to contact a specialist as soon as possible before an extended breakdown. 

Apart from this, damaged air filters or ducts can also create banging or popping sounds. When the heater gets turned on and off, the steel air ducts in your home can expand or contract. Hence, if you hear a popping noise, there could be problems like shuttered vents, fragile ducts, or a clogged air filter and, it is advisable to get it fixed timely. 

  • Whistling Noises

A high-pitched screeching noise could indicate several issues, but it usually means that a component needs to be rebuilt or repaired. Such sounds are commonly produced by worn-out parts such as a corroded air compressor belt or a nonfunctioning blower engine, leading to furnace problems that require more extensive repairs.

These are usually simple fixes, but it’s best to get them taken care of before your heating system suffers any harm. Of course, these aren’t the only strange noises your furnace can produce. It’s a good idea to consult a technician if you hear weird noises coming from your furnace. Avoiding these sounds may result in more costly repairs in the future.
