Whether it’s the beginning of a new season or the dead of winter, the burning smell of a furnace brings a sense of dread. Why does your furnace smell like it’s burning, and what can you do to avoid costly repairs?
Your nose may tell you otherwise, but a burning smell coming from your furnace isn’t always a reason to panic. Numerous factors can contribute to this odor, ranging from harmless to bad news. The following are a few reasons why your furnace may smell like it’s burning.
An air filter’s purpose is to block foreign particles, not to restrict airflow. A clogged filter can cause your furnace to overheat or build up excess hot air.
You’re probably familiar with that “first use” odor when you turn your furnace on for the first time each winter. Dust settles inside the vents and burns up when the furnace kicks on, causing a burning smell. If you haven’t run your furnace in a while, this is probably the source of the odor.
A furnace’s blower maintains the internal temperature of the furnace. If it breaks down or malfunctions, it can lose control of the temperature and cause your furnace to overheat.
Electrical fires are dangerous and can cause a lot of damage. If you do smell a burning odor, it is important that you check all electrical wires and lines to ensure they aren’t malfunctioning.
In oil furnaces, you need to change your oil filter as often as the package directs. Burning oil can be harmful, so make sure you don’t procrastinate.
Occasionally, loose dirt, debris, and other particles can find their way inside your furnace. When this happens, the heat burns them off and causes an odor. Small particles aren’t a huge problem, but you should check your system to ensure there aren’t holes or leaks.
Gas leaks are dangerous and can certainly cause a burning odor. Inspect your gas lines to ensure no leaks are polluting your home’s airflow.
So, what are the steps to eliminating your furnace’s burning odor?
Even if the problem is harmless, the first step is to turn off your furnace. Don’t turn it back on until you are positive that the issue has been resolved.
Check every unit, line, etc. Look for visible signs of damage like holes, dents, or rust.
Dust and wipe down everything you can reach. Pay particularly close attention to areas that heat up significantly.
Always check your air filter to make sure it’s clean and functioning. Make sure you follow the manufacturer’s instructions for changing the filter.
If the odor’s source is not immediately evident, call an HVAC technician. It is always better to eliminate dangerous situations before they happen.
The best maintenance is preventive maintenance. Avoid a burning odor by applying the following 2 tips.
Again, your health and comfort should be a priority. Address problems as they arise and save money on long-term repairs and replacements.
You should have your system services by a professional on an annual basis. This ensures that everything runs smoothly and safely.
