Noises coming from your furnace mean many things, and it is important to figure out if it is normal or a Furnace Repair is needed. In addition to sometimes scaring the living daylights out of you, they may signal some other problems that could be coming from your furnace.
Some of the issues you can take care of on your own, and other times, we recommend consulting a professional. Below are descriptions of various furnace noises you may here and what they could mean.
Let’s start with the bang. If you hear a loud bang or a boom coming from your furnace, this could be gas buildup and a delayed explosion. The same thing could happen if you leave the propane on for a long period of time before lighting your BBQ.
There might be other reasons for the banging sound, and it is recommended contacting a professional.
If you hear a groaning or deep rumbling noise, it might be an indication something is wrong with your motor bearings, gas burners, or pilot light.
A house shaking rumble could be unburnt fuel in the combustion chamber, and there is a possibility it continues to burn, even after being shut off.
If you hear any groaning or rumbling noise it is recommended to contact a professional immediately.
Hearing a Furnace Rattle could mean several things. If the rattling comes before your blower turns on, it could be due to a cracked heat exchanger. This may turn into a serious issue as it is the main cause for carbon monoxide leaks. Call a professional ASAP.
If the Rattling comes after the blower comes on, it could mean there are loose ductwork connections. Another cause of persistent rattling and rumbling could be an imbalanced blower wheel, motor, or a loose screw. Best to contact a professional.
Hearing your Furnace Click is probably your ignition kicking on and is normal for your furnace.
However, if there is excessive clicking then it could mean there is a problem with your flame sensor. Over time this sensor could accumulate a large amount of dust and debris. You may want to call someone to come in and clean the sensor or have them replaced.
A Scraping Metal sound could mean there is a problem with your blower wheel. It might be something is stuck in the blower assembly, or something might be broken. Best to call in a professional to assess the problem and provide recommendations.
