October is generally a spooky time of year because all the scary movies are on television and we start thinking about Halloween. It is also the time of year that some of use start turning on our heat. So to add to the dilemma many of us start hearing spooky noises coming from the furnaces in our Virginia Beach, VA homes. Whether it is a deep rumbling, high pitched squealing, or a unsettling rattling, the noises from your furnace are trying to tell you something is wrong.
A rattling noise could be simply from ductwork cooling down and contracting after the heat shuts off. This is something you really would not need to work about. But, a rattling noise can also be a sign of an imbalanced blower motor or wheel. Most furnace noises are caused by a problem with the blower motor which pushes the cool or warm air through the filter into the ductwork. Lubrication or a new belt may solve the problem, but you will want to have an HVAC technician come and diagnose what exactly needs to be done.
Deep rumblings or a loud boom
This is one sound you are going to want to have diagnosed as it can be stemming from a variety of things including ducts expanding and contracting as they cool, to intricate parts of the furnace. Those deep rumbling signs may be an indicator that the furnaces gas burners are dirty or that the pilot light needs to be adjusted. It could also be that your gas valve is defective.
Noises are a common part of a house and a heating and cooling system. But if you start to hear a new noise coming from the furnace, or that occurs when you have the heat on, you will want to call a heating expert. Ignoring the noise could lead to serious damage that could have easily been prevented with a quick tune up or a simple replacement part. So as you turn your heat on this winter keep your ears alert and see if your HVAC system is trying to tell you something.
