Why does my furnace smell like formaldehyde?
If the odor has a distinct chemical smell similar to formaldehyde, chances are that your furnace’s heat exchanger is broken.

Only those with a heat pump will have to deal with this problem for more than a day; a furnace gets hot enough to kill off bacteria, but a heat pump does not produce that level of heat. Heat pump coils will typically only reach between 105 degrees and 130 degrees Fahrenheit, which is the perfect temperature for microorganism growth.
Why does my furnace smell like rotten eggs?
If you notice a rotten egg smell when you turn the heat on, you likely have a serious problem that you must deal with immediately. This heat smell is typically emitted from gas furnaces and usually indicates that there is a gas leak in your home. A furnace is fed natural gas through enclosed gas lines. The gas then ignites inside the furnace to create heat and warm your home. However, sometimes these gas lines or the furnace itself can have leaks, allowing the gas to escape the heating system and seep into your home. If there is a leak in the gas lines, a small spark could cause a deadly explosion or ignite a fire.
