What Do Furnace Noises Mean?
Your heater can’t verbally communicate with you. But, if it’s making a consistent loud noise, it can help you determine the source of the problem. These sounds can be annoying, but it’s crucial to monitor them to know if repairs are necessary.
Banging At The Start Of Cycle
When turning on your furnace, listen for any banging. This situation may mean there is a possible delay in ignition. Your combustion chamber can fill up with gas, causing a loud noise to echo throughout your furnace.
A clog in your ignition can be dangerous if ignored. You shouldn’t attempt trying to correct the issue on your own! A professional technician can examine your furnace and safely perform repairs.
Irregular Banging
Although it is the same sound, irregular banging can signal a problem with your ductwork. Your ducts can expand and contract due to changes in pressure and temperature. This won’t cause issues with your system but can be removed with a few tweaks to your ductwork!
Rattling
Broken and loose parts can cause the occasional rattle in your furnace. Since your system is comprised of many components, it can be challenging to discover the source of the problem. An expert can inspect your heater to find the issue and replace any faulty parts.
Whistling
Your air filter may need to be changed if you hear your furnace whistling! Airborne contaminants can block airflow, creating an annoying high-pitched sound. The spooky sound can be corrected with a filter replacement! Professionals recommend that you replace your air filter every three months.
If the noise persists, you may have a leak in your ductwork. You can inspect your ducts and vents for damage, but a professional can perform repairs to correct the issue.
Persistent Humming
Humming or low-pitch may signal a severe issue with your heater. This noise can be difficult to hear at first but typically grows louder as the problem persists. A hum usually means a problem with an electrical component, which can be dangerous if not taken care of.
A malfunctioning blower component or transformer can produce this sound. Since electricity can be hazardous, you should have a professional inspect your system. If this problem continues, you risk significantly damaging your heating system.
