Why Does Your Furnace Smell When You Turn It On?

November 01, 2016

The weather is getting colder in St. Louis and we must turn our furnaces on soon. This time of year we get a great deal of furnace repair calls from homeowners expressing that they smell something when they turn their furnace on for the first time. Most likely you haven’t been using your furnace since it was last cold. In that time dust may have collected inside your system. The first time you turn on your furnace, that dust will burn off. The smell from this will travel through your ducts throughout your house. This doesn’t usually present any sort of hazard and the smell will normally be gone after a little bit. However, if the odor does not decrease after a bit, please notify one of our pros.

Another reason you could be smelling an odor from your furnace is that your air filter might have gotten clogged. This can cause your blower motor to run harder than necessary and could cause the motor, and/or the furnace to overheat.

Your furnace is going to be an key part of your life in the near future. If you haven’t yet scheduled your annual furnace repair, now is the perfect time. Our professionals will be sure your system is running safely and clean the internal components before you have to worry about a burning scent.
