Why Does My Monterey, TN, Furnace Smell Weird?

January 17, 2021

The presence of odors coming out of your furnace can often mean something is wrong with your system. If you’re experiencing strange smells emitting from your Monterey, TN, furnace, there are several possible causes for the issue.

Rotten Eggs or Sewage

It won’t take you long to notice the stench of rotten eggs coming from your furnace. While this smell is one of the strongest, it’s also one of the most dangerous. If your heat exchanger has a crack in it, your furnace can leak carbon monoxide.

People usually call carbon monoxide the “silent killer” because it’s a naturally odorless gas. However, chemical companies put something in it that gives it a strong, sulfuric odor, so you become aware when you have a leak. This is often the reason for the smell of rotten eggs.

Musty Odor

When you first turn your furnace on, you may notice a musty odor coming from your vents. While this doesn’t always mean there’s something wrong, it can mean that there’s bacterial growth in your ductwork. Fortunately, we offer duct cleaning services that can help eliminate these smells.

Burning Odor

A lot of people panic when they smell a burning odor coming from their furnaces. When you turn your furnace on for the first time, it’s not unusual to smell dust burning off of the elements. However, if this smell continues, you should turn off your furnace, cut off the gas source and call a professional to check out the issue.

While every odor that comes from a furnace isn’t a sign of trouble, you should always call a professional HVAC technician if the odors persist. Whether you need a repair or replacement, our team of professional service techs can provide the services you need to keep your home comfortable, safe and efficient.
