It’s normal for a furnace to smell when you first turn it on for the season. But you must understand the differences between normal odors and those that are concerning. Recognizing them could alert you to contact your HVAC contractor promptly and avoid a significant issue. Below are a few of the most common smells your furnace might emit.

How to Understand Different Furnace Odors

1. Rotten Eggs

The smell of rotten eggs is easy to discern—and there’s a reason why. Gas companies scent their fuel with this sulfuric odor to alert homeowners of a leak. If you smell this potent aroma in your home, evacuate right away and contact the gas company. They’ll need to turn off the gas supply before your HVAC service can fix the problem.

2. Burning

A burning odor is not unusual. It’s the same odor you’re likely to detect when you first turn the heater on for the season. When dust, dirt, and grime accumulate inside the furnace during the offseason, the device will burn it away. It shouldn’t continue for long, however. If you notice that it continues to smell, replace the air filter first. Otherwise, your HVAC contractor will need to check the internal parts for possible damage.

3. Metallic

You should be alert to metallic odors, too, especially if they smell like something is sizzling, or wires are burning. Occasionally, this problem occurs when an interior part overheats. Some components, like those made with metal or rubber, may burn away if they’re especially old or if the furnace hasn’t had service recently. Be mindful of the possible severity of the problem; turn the unit off until it’s resolved.
