Why Does My Furnace Smell? (Common Furnace Smells & What They Mean) (Part 1)

Have you been noticing strange odors in your home whenever your furnace is cycling? Do you suspect that those strange odors are coming from your furnace? When you notice weird smells coming from your furnace, it can sometimes be an indication that your furnace has some sort of problem that needs to be addressed, and possibly a sign that repairs or replacements may be needed as well. Here are some of the most common smells and what they mean: Why Does My Furnace Smell

Rotten Egg Smell

One smell that you should pay extra attention to if you notice it is the smell of rotten eggs. When you smell rotten eggs in your house, it’s never a good sign. Rotten egg odors are an indication that your furnace has a gas leak, which can be extremely dangerous and hazardous for both you and your home. If you detect rotten egg odors when your heating system is cycling, turn off your system immediately and call your local HVAC contractor ASAP for emergency furnace repair services.

Burning Smell

Another common furnace odor is a burning odor. While a burning smell oftentimes simply indicates dust burning when you first turn your furnace on for the season, if the smell persists, that’s a sign that something may be wrong with your furnace. Another possible source of the burning smell can be due to having a dirty or clogged furnace filter. However, if you’ve cleaned or replaced your furnace filter and the smell continues to persist when your furnace is cycling, then that’s a sign that something is wrong and that your furnace needs to be inspected and repaired by an HVAC professional as soon as possible.

Metallic Smell

Lastly, it’s also not uncommon for homeowners to notice metallic or plastic-like smells when their furnaces are running. A metallic odor is generally an indication that some components in your HVAC system are loose, or that your furnace is overheating. The same goes for plastic smells–they are an indication that your furnace components are loose or overheating, and that your furnace requires repairs or perhaps even a replacement.
