4 Reasons Your Furnace is Making Weird Noises

Why Is My Furnace Making Noises?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

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

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.
