It’s normal for heating systems to make noise. Furnaces can make a low hum or even rumble under normal operation. However, you should be concerned if you start hearing clicking noises. You need to have your equipment checked by professionals if it’s making this kind of sound.

Read on to learn why your furnace is clicking from a local HVAC maintenance expert.
What causes furnaces to make a clicking noise
The flame sensor, or thermocouple, is a component that detects the presence of a flame and signals the gas valve to open. If it’s damaged or clogged with dirt, it won’t send the signal, making the ignitor click. Another thing that can cause clicking noises in your furnace is a broken gas valve. A jammed or clogged valve may not produce gas, and when this happens the ignitor will click nonstop.
In some cases, the fan or inducer can produce clicking noises if they’re defective. If you have an electric furnace and it makes clicking noises, this means that your equipment needs to be repaired. Moreover, this noise can also come from your ductwork if something gets stuck in it. Whether you need a furnace repair or duct cleaning, you can turn to Bill Reynolds Heating & Air Conditioning.
