In an ideal world, all the appliances you’ve installed in your house will make your home a comfortable place to live in without creating any problems. It would be even better if none of your appliances make any noise while they are at it. Unfortunately, the world is not perfect, and appliances like your furnace make sounds when they operate.
However, if you hear odd sounds from your furnace that do not sound normal, it could be a sign that something is wrong with your unit. We will discuss some of the strange noises your furnace might be making so you can understand why you need to call us for HVAC services in Glendale, AZ.
Strange Noises from Your Furnace
Here are some of the strange noises that indicate a problem with your furnace.
1. Banging noises
If you hear banging noises coming from your furnace as it turns on, it could be a problem with the ignition system. The thermostat signals the furnace to turn on the gas valve so it can start. The pilot light should ignite the gas immediately. However, any ignition system issues can cause the gas to accumulate in the combustion chamber and create a loud bang.
2. Whistling noises
Furnaces make humming sounds when they operate, but a whistling sound could be a sign of trouble. If you hear whistling sounds, it means that something is interfering with its airflow. Whether there is a leak in the ductwork, closed vents, dampers, or a blocked return, it is a problem you cannot ignore.
3. Clanking noises
A properly working furnace will never make clanking noises. If it is creating a knocking noise inside, the blower fan could be malfunctioning. Furnaces can start making clanking noises if the fan becomes misaligned, and the blades are hitting other parts of the furnace or the walls of its housing. You should not ignore the problem. Turn it off and call a professional to fix it because it could severely damage your furnace.
4. Rumbling noises
Furnaces make a whoosh or roaring sound when it completes a cycle. You should keep your ears open. If that sound ever changes into a rumbling noise, it could mean something is wrong with your furnace. The rumbling can happen due to problems with the burner or if gas accumulates in the combustion chamber even after the cycle is complete. It could cause a lot of problems and even contribute to high carbon monoxide levels in your house.
Call a Professional Immediately
If you hear any of these unusual sounds, you should not waste time and call a professional to immediately repair your furnace. Ignoring these problems could lead to severe damage to your heating system that could cost a lot for repairs.
