Why Does My Furnace Have A ‘Burning’ Smell?

Did you know, according to the National Fire Protection Association, heating equipment has been ranked as the 2nd highest cause of house fires?

The smell of something burning is always scary, so we are careful with candles, fireplaces, and anything else that could cause a fire.

What about our heating systems?

A burning smell in a heating system can have many meanings:

  1. There is dust in the combustion chamber.
    A burning smell at the beginning of the season is pretty common. The dust and particles from summer has built up in the combustion chamber, and now has to be burned away.  This process should only take a few hours to a day.
  2. Your air filter may be dirty.
    Air filters should be checked monthly and replaced every 1-3 months. If this is not being done, you risk the chance of dust building up in your furnace and producing a burning smell.
  3. The blower in your furnace may become overheated.
    Whether due to a clogged filter or an improperly-sized system, a furnace blower can become overheated. A burning smell could be an indicator that your system is overworked.


**Quick Tips**

Make it a habit of doing regular inspections, searching for items lying around your furnace. Keep toys, clothes and other flammable objects away from your unit. Even though you may be able to correctly diagnose these different problems with your furnace, it is always safer to contact Logan Services and have a professional take care of it for you.
