Why Your Furnace is Being Noisy

With Halloween behind us, you don’t want to have scary sounds coming from your furnace.  Here are some of the reasons you are hearing these noises:
Screech – never a pleasant sound to say the least, your furnace makes this sound when the motor or blower wheel of the fan is turned on.  You most likely have a faulty motor, belt or motor bearing which you definitely need to get your furnace looked at and fixed.
Boom or thump – these noises usually happen when the ducts in your furnace expand and contract in cold weather.  The sound may mean that your furnace has dirty burners or is getting a build-up of gas from delayed ignition.
Rumbling or rattling – the rumbling noise may be caused by a buildup of grime on the heating elements which causes the unit to strain.  The worst case scenario for this sound, you have a leak in the heat exchanger which can allow carbon monoxide gasses to work their way into your home.
It’s best to get your furnace checked if it is making any of the above noises to make sure your family is safe and your home is comfortable.  Contact Family Air today for a heat inspection.
