If the furnace in your Highland Village, Texas, home is making some strange noises, you may be wondering what they mean. Certain sounds shouldn’t concern you, but others can indicate a more serious problem. A heating system shouldn’t make a lot of noise, so any sound that is out of the ordinary should be investigated by a professional.
If your furnace is making a noise like a banshee, the experience can be quite startling. In most cases, a screeching sound indicates an issue with the motor, such as a bearing that is wearing out or has slipped out of place.
You shouldn’t try to fix any problem with your furnace’s motor on your own, as you could end up causing more damage. Contact an HVAC technician to take a closer look.
Whining or Humming
A humming or whining sound can indicate a motor mount that has come loose, which can be a risky situation if not properly addressed. The motor in your furnace is mounted in place to prevent it from sliding or moving as it runs. If you hear this sound, turn off the heating system right away and call a technician to investigate what is causing it.
When the furnace sounds like it’s making popcorn, you may think something serious is awry. However, this is one of the noises that actually isn’t too worrisome. The ducts that allow air to move throughout your home are made of metal and can expand and contract as the system cycles on and off. The expanding and contracting process may result in a popping noise.
Hearing crackling coming from your furnace may also seem like a major problem, especially since this sound often indicates the presence of excessive heat. However, in a heating system, crackling usually occurs when the heated metal components within the unit start to cool down as the system cycles off.
