Afer the warmer days are over you need to switch on your heater again to survive the cold weather. Sometimes, you may get a burning smell coming from your heater. You should understand why it happens so that you can fix it before anything dangerous happens.

Burning dust

Dust or other debris may accumulate on your heater if you leave the heater off for a long time; for example, during summer. So, when you switch it on suddenly, the dust gets burned off. This plastic smell mixes with the warm air in your house. That’s when you begin to get that odd smell. This is something normal, particularly at the beginning of the winter. The smell can last for more than 30 minutes.

Clogged filters

When your heater’s motor gets overworked, it produces a burning smell. When your heater’s motor is overworked due to clogged filter, it also produces a burning smell. You need to change your air filter, else the burning smell will increase, and the motor may get damaged. It is a good idea to change the filter at the beginning of the colder month.

Damaged furnace

Because of age or lack of maintenance, your systems motor can get overheated. If you put some oil, the motor may start to work again. But the chances are that it can be a serious problem as well. If the smell doesn’t go away after you put the oil, you must turn off your system and call a professional HVAC technician.

Closed vents

If the vents in your home are closed, then you may get the burning smell. The HVAC system may try to push out the warm air to your home, but the air becomes trapped due to the closed vents. When too much hot air gets trapped inside, you may get a burning odor.
