Typically, the only time homeowners notice a sound coming from their furnace is when it kicks on. At this time a click followed by a low, humming sound can be heard. While it may be normal to hear a furnace making noise at the start of a heating cycle, disruptive sounds that occur throughout the entire heating cycle may indicate a moderate to severe issue with the heating system.
Furnace Noises and What They Mean
Have you noticed the heater in your home making scraping, screeching, banging, or other noises while running? These sounds can be warning signs that something is wrong with the internal workings of your furnace system. To help identify the issue, we’ve compiled a list of the most common furnace noises. Find out what these sounds can mean and when it’s time to call in an expert.
Scraping Noises May Indicate a Twisted Fan Blade
If your furnace is making noises that are identical to nails on a chalkboard, this is an indicator of loose or broken parts inside the furnace. Oftentimes the fan blade is off-balance or bent, or screws or other parts are loose. When a heater is making this noise, calling a certified technician should be your first move.
If caught early, the issue should be an easy fix. Prolonging the call can lead to more issues, broken parts, and higher repair bills.

Screeching Sounds Are a Sign of Damaged Motor Bearings
If your furnace is making a screeching noise, this is a sign of issues with the motor bearings or bad belts. This is also a common issue with automobiles. The screeching will be heard anytime the furnace kicks on and will continue while it’s running. Anytime internal components are having issues, it’s best to call a certified HVAC repair technician.
By replacing a belt or lubricating the bearings, the technician will eliminate this annoying furnace noise and restore the efficiency of your system.

Component Obstruction May Be a Culprit of a Thwapping Noise
Does your furnace sound like baseball card-clad bicycle tires? While not the most irritating noise, a furnace will make a thwapping noise if something is interfering with the fan blade and should be looked into quickly. Anytime there is strain on an internal component, the efficiency of the furnace is lowered and the probability for additional damage increases.
Banging & Popping Sounds Are Caused By Temperature or Humidity Variations
As the temperature and humidity levels of the air in our homes increases and decreases, popping and banging sounds can occur within the HVAC system’s ductworfurk. These noises most often occur upon starting the furnace, and as the heat makes its way throughout the system, they should stop.
If the furnace unit itself is making a banging or popping noise, problems with the internal combustion unit may be at play. If not attended to, the issue can put unneeded stress on the internal furnace components, leading to breaks and the need for larger repairs down the road.
