As was already indicated, there isn’t always a need to be concerned when you turn on the heat and smell something off. “Why is there a burning smell?” you may be asking yourself. Spend some time inspecting your furnace to see if there is anything that should concern you right now.

Let’s go over some of the most frequent causes of burning smells coming from your furnace when you turn on the heat for the season.

1. Dust Burn-Off

When a furnace has been idle and unused for a while, dust buildup is a frequent occurrence. Your furnace gathers layers of dust and detritus during the off-season, just like unused goods might do in your house. When you first turn on your furnace, the built-up dust slowly burns away. The dust burn-off may fill your entire home with a distinct burning odor as it travels through your ductwork. If the smell persists after a few minutes, you should call a local HVAC expert to check your furnace for any problems.

2. Dirty/Clogged Air Filter

Before reactivating your furnace for the season, make sure the filter is clear and in good condition. A common cause of problems with the HVAC systems, including an unpleasant odor, is dirty, unaltered filters. Your furnace’s air filter can be changed to prevent it from emitting a burning odor. The blower motor works harder when the air filter is soiled and clogged, which can lead to overheating and produce a burning odor. Additionally, a blocked filter allows dust to accumulate on the furnace, which burns off and emits a burning stench when the furnace is heated.

3. Electrical Problems

You should call an HVAC expert right away if you smell burning electricity coming from your furnace. Due to the chemicals and plastic used to cover electrical components heating up and beginning to melt or burn, an electrical fire typically has a fishy odor.

This is a problem since it puts your family and you at risk of an electrical fire.
