Burning smell when turning on the heat? Don’t panic, it’s likely just dust

As cooler, fall temperatures creep into Mid-Missouri, you might be turning on your heat for the first time in months.
If you are turning up the heat, you may notice a burning smell; however, there’s likely nothing to worry about if the smell dissipates within a few minutes. When furnaces haven’t been touched for months, dust tends to collect. When the heat is turned on for the first time, that dust burns off, creating a burning smell.
An additional reason for that burning smell would be clogged filters. You should change the filter in your furnace or HVAC system, as it can restrict airflow and cause your system to overheat.
If that burning smell sticks around when turning on the heat, it could be a few things:
Electrical issues, such as damaged wires or a malfunctioning component.
The blower motor or other parts of your system are overheating or not working properly.
If you see smoke or flames, immediately turn your system off and call 911.
As you turn on your furnace, it is best to slowly transition to turning on the heat. An instant jump from cool to warm temperatures could damage your system, leading to expensive repairs.
During this time of year, it’s a good time to check your carbon monoxide alarm. Since your heating system may run for an extended period, it is essential to have a functioning carbon monoxide alarm in your home.
