Pretty soon, we will start experiencing winter. When we first turn on the heater, many people wonder what the banging sound is.
You cross your fingers, hoping that nothing bad happens. Unfortunately, sometimes you will hear a loud BANG sound when you turn on your heater. This can either be an easy fix, or something potentially dangerous to your home’s safety. Here are a few pointers to help you figure out what may be going on, and how to prevent it from happening.
So what’s that banging sound coming from your furnace?
2 Reasons Why Your Furnace Would be Making a Banging Sound.
- Popping Ducts – During the heating cycles, your ductwork contracts and expands. When this happens, it’s not odd that it would make a BOOM sound or something of the like when the pressure changes inside of your ducts due to the air handler turning on. Pressure buildup in your ducts via a clogged air filter or some vents that are closed in your rooms can cause this sound to get louder and occur more frequently.
- Dirty burners on your furnace – Dirt can build up on your furnace in large amounts when your furnace filter is dirty or if you’re not getting the annual maintenance on your system. Whatever the case may be, this dirt will delay the ignition of the gas fed to your system, and build up will cause a mini explosion when the ignition starts. This problem is a bit more serious and a bit louder as well, and may lead to a cracked heat exchanger.
So what should be my first step?
If this furnace noise happens as soon as you turn it on, you should call the professional heating team at Will’s All Pro to get one of our licensed technicians out there to solve the heating problem for you. If the sound is being caused by delayed ignition, you definitely don’t want to waste any time.
