When a furnace operates normally in Pennsylvania, it makes a soft humming sound. This is the sound that you usually don’t notice. But when it starts making some unusual noises, you suddenly pay attention to it. This is the time when your furnace demands immediate care and a professional technician. Though it might be working well at that time and keeping your residential or commercial place at a comfortable temperature, this is not usually an issue you should leave unaddressed. If you do so, you are at risk of experiencing major repairs ahead.
This blog post covers the core causes that make your furnace produce unusual clicking sounds. It also mentions some of the expert tips to prevent this issue in the future. If you need furnace repair services from certified experts, you can contact Lehigh HVAC right away.
A furnace can make unusual sounds for various reasons. From electrical components to mechanical damage and neglected maintenance, everything contributes to similar symptoms. Here is a brief overview of some of the most common causes.
A gas valve is responsible for supplying fuel to the ignition components. When this valve is faulty, it can’t regulate the gas flow to the combustion chamber. The result is that the furnace requires fuel frequently, and that’s why it makes the clicking sound. You can differentiate this issue from other issues by checking whether the furnace makes sounds continuously or at frequent intervals. If you hear clicking sounds at intervals, it is likely due to gas valve issues.
The flame sensor sits around the rear of the furnace. This small component is responsible for turning off the system when the burner flame is absent. If the flame sensor is corroded, dirty, or clogged, it fails to detect the presence of the flame. The result is that you hear clicking sounds repeatedly. The solution to this problem lies in inspecting the flame sensor and replacing it if it is faulty, outdated, or corroded.
The inducer fan is a very critical component of a furnace. It plays an important role. It clears any leftover fuel in the combustion chamber and also supplies continuous oxygen to the components. If this inducer motor is outdated or has heavy wear and tear, it fails to play its normal role, and that’s why the furnace keeps producing clicking sounds.
Though ductwork is least related to clicking sounds, it can sometimes be the culprit. The issue arises when there are cracks and gaps in the ductwork. Air escapes through these tiny pores and creates noises that seem similar to clicking furnace noise.
A furnace installation is a major investment at any residential or commercial facility. It needs the same attention and care as other expensive electronic appliances. It keeps the system running at peak performance and maintains its error-free operation. Here are a few tips from Lehigh HVAC experts to prevent unusual sound issues.
Schedule annual HVAC maintenance to inspect and service key components before winter.
Replace air filters regularly to prevent restricted airflow and system strain.
Keep air vents and registers open and unblocked throughout your home.
Clean the flame sensor and surrounding ignition assembly periodically to avoid buildup.
Inspect ductwork for visible cracks or leaks and seal them properly.
