Faint clicks when your furnace starts running are normal, just like a low humming noise when it’s in operation. However, strange sounds coming from the system can point to significant problems. Find out more about strange furnace sounds and why they deserve immediate attention today.
The High Cost of Being a Procrastinator
When a furnace starts to fail, it does not always stop working completely. Instead, it starts working much harder and longer to produce the same amount of heat. Every problem that your furnace runs into has the chance to make it less efficient, costing you more money to accomplish the same results.
While not every furnace problem causes sounds, those that do need to be addressed immediately. As soon as you notice a different noise coming from your furnace, let a professional diagnose and repair the problem so you can avoid sudden spikes in monthly utility bills.
Common Furnace Sounds and What They Really Mean
Every house has its own unique creaks. However, certain noises from your vents should definitely make you sit up and take notice. A loud boom or bang when the heat starts is often a sign of delayed ignition, allowing gas to build up before igniting. This issue can cause a crack in your heat exchanger, the component that keeps dangerous exhaust fumes out of your breathing air so that you can avoid carbon monoxide poisoning. If that metal box cracks, the furnace is usually ruined. You might have to spend thousands of dollars on a total replacement.
A clicking noise is normal when the furnace begins running, but it shouldn’t persist. If it does, you’re probably dealing with a faulty ignition.
If your furnace screeches or squeals while the motor runs, you have a slipping belt or a bearing that needs lubrication. Replacing or lubricating parts is an easy task for a technician.
Rattling noises can be annoying, but they generally point to one of the most minor problems that our team runs into. The panels on the outside of your furnace can become loose over time. Tightening up a few screws can generally resolve your problems with rattling noises coming from the system.
