Summer has ended, and it has happened. Temperatures have dropped just enough to create a nip in the air, and you’re forced to turn on the heat. Your home begins to warm, but wait, what is that burning smell? First and foremost, it is important to remain calm; turn the furnace off, and go to the area of your house where the unit is located. Confirm that there isn’t a fire or the need to call 9-1-1. Once you decide that you and your family are not in immediate danger, you then can take a sigh of relief and start to wonder what could have caused that alarming smell. Here are a few conditions that can generate this odor.
What’s Giving Off That Burning Odor?
Combustion Chamber Dust
It is not uncommon to experience a burning smell when you turn on the furnace after it has sat idle for an extended period of time. When a heating unit isn’t in use, dust and dirt settle in the combustion chamber. Once the chamber ignites, debris will sear off, and produce a burning odor or scent of smoke. From there, a blower pushes warm air through the ducts, which eventually gets delivered into your home. If this is the source of a burning odor, the alarming stench will dissipate quickly. If needed, open a window or two to expedite this process.
Do you remember the last time you changed the furnace filter? If not, this should be the first place to check. Filters in a forced-air furnace serve a vital role in delivering warm air to the rooms in your home. Their job is to remove particulates (such as dust, pet dander, pollen, mold spores, and more) from the air before the unit gets warmed up. When a filter is dirty or soiled, the airflow becomes compromised, and it is not be able to blow freely through the fibers. When this happens, there’s potential for the unit to overheat and start a fire. But, if dirt is the only culprit, a clean filter should eliminate an occurrence of such smells. In fact, it is important to change filters every 30 days or follow directions on the specific filter’s packaging. This will help decrease odors and provide longevity to your furnace.
The function of a furnace blower is to draw heat from the furnace and distribute it throughout your house. It also maintains the internal temperature of the unit from getting too hot, and just like other mechanical devices, it has the potential to breakdown from time to time. If the blower stops working, it could cause the furnace to overheat and give off a burning odor. Contact a professional at Four Seasons to provide a full evaluation of your unit.
