Your furnace does the important job of keeping your home warm and comfortable during the cold parts of the year. Since you rely on this appliance so heavily, it is a good idea to monitor its operations, especially during the months when it is used the most, and to have a certified HVAC (Heating, Ventilation and Air Conditioning) technician perform routine maintenance on your furnace and carry out repairs when necessary.
Like any other appliance, a furnace will occasionally suffer from functional problems, and as its life goes on its age will start to show. One sign of this that you may notice is unusual noises your furnace may make as it operates. Though this can be alarming, it’s not always something to worry about. Recognizing what causes different noises will help you know when your furnace is behaving normally and when it is in need of heating service in Richmond, Virginia.
Furnace Noises To Listen For
A screeching noise can be indicative of a problem with your furnace’s motor or one of the motor’s bearings. Repairs may be necessary.
A high-pitched metallic sound may simply be a minor misalignment of the furnace’s fan motor or blower wheel, or a warped mounting plate. It may be possible to adjust these components yourself, but if you aren’t sure, contact a trained professional.
A rattling noise when the furnace starts up might be caused by a problem with a motor bearing. A rattling noise as the unit shuts down, however, is normal as the metal cools off and probably does not require attention.
Various Metallic Noises
Small, occasional pings or pops are generally just your home’s ducts expanding and contracting as the temperature changes. Louder, booming sounds coming through the ducts more frequently might indicate dirty furnace burners or a faulty gas valve—both issues that should be dealt with by a technician.
Vibrating or Whining
These noises are very irregular and you should contact a professional immediately upon hearing them.
Getting to know the sounds made by your furnace a little better lets you determine when heating service in Richmond, Virginia may be necessary.
A heating system is sometimes part of a larger HVAC system. This equipment is usually incorporated into a home when it is first constructed, or installed and should be maintained by a Richmond-area heating service company employing professional HVAC experts.
