Furnace Odor: Why is Your Furnace Emitting a Burning Smell?
The occasional unusual smell coming out of the furnace in your Durham home is generally not a big problem, but it is important that all homeowners know when these smells are a sign that something dangerous is taking place.
Here is a look at some of the most common causes of these unusual odors and when you should start being concerned about them.
The Filter Has Become Clogged
One of the most important maintenance tasks in a home is to change out the HVAC system’s filters a few times per year. Depending on how often you use your HVAC system and the type of filters that you purchase, these might need to be changed as often as every 30 days.
When the filter becomes clogged, it will force your furnace to work much harder in order to keep your home at a consistent temperature. This increases its internal temperature and can result in unusual smells.
Dust Is on the Furnace
No matter how clean you keep your Durham home, dust is sure to find its way into the furnace at some point. This generally takes place during the warmer seasons when the furnace goes unused for six months or longer.
The easiest way to avoid this is to have your system professionally inspected and cleaned before you turn your furnace on for the first time. In most instances, the burning smell that you notice during the start of the cold season is not dangerous, but dust can be flammable in sufficient quantities.
Damaged Electrical Parts
Electrical fires are extremely dangerous and should never be taken lightly. When electrical components become damaged, they will often produce a smokey smell that can be described as metallic as well.
You might begin to smell this odor when wires have become too hot and are burning away at their protective covers. It can also take place when the furnace’s motor has burnt out and needs to be replaced.
Debris in the Furnace’s Chimney
Most furnaces have an exhaust vent or chimney that sends carbon monoxide outside of the home. During the spring and summer months, animals such as birds will often find their way into these vents to make a nest.
When the furnace is turned on for the first time in the fall, this debris can produce an incredibly strong smell. Inspecting these vents is just one more task that is carried out during seasonal service calls.
