Understanding Furnace Smells: What's Normal and What's Not

As the seasons change and the temperatures drop, it’s time to switch on your furnace and welcome the cozy warmth into your home. However, you might notice a burning smell when you first turn on your furnace. This can be alarming, but in many cases, it’s completely normal.

Why Your Furnace Smells Like It’s Burning

The first time you turn on your furnace in the cooling season, it may emit a burning smell. This is typically caused by dust that has settled on the heating elements burning off. Fortunately, this smell should dissipate quickly and is usually nothing to worry about.

When to Take Action

While a brief burning smell is normal, pay attention if it persists or if you notice other unusual scents. Here are some important ones to be aware of:

  • Dead Smell: If your furnace emits an odor that resembles a decaying animal, there might be a pest that has unfortunately found its way inside. It's wise to have it checked professionally to ensure nothing is blocking the airflow.
  • Gas Smell: A gas odor is serious, as it could indicate a gas leak. If you detect a lingering gas smell, shut down your furnace immediately and contact us or your gas company right away.

Ensuring your furnace is in good working order creates a safer, more comfortable home environment. If you have any concerns or need a professional check, don't hesitate to reach out to us at Nemchek Heating & Cooling.
