Why Does My Furnace Smell Like Sewer

Why does my furnace smell like sewer?

If your furnace is emitting a sewer-like smell, it can be a cause for concern. There are several possible reasons for this unpleasant odor:

• Blocked or clogged sewer vent pipe: If the sewer vent pipe is blocked or clogged, it can cause sewer gases to back up into your home through the furnace system.
• Cracked heat exchanger: A cracked heat exchanger can allow combustion gases, including sewer-like smells, to enter the air being circulated by your furnace.
• Sewer gas leak: If there is a sewer gas leak in your home, it can be drawn into the furnace system and distributed throughout your house.
