Why Is My Furnace Making A Banging Noise?

Why Is My Furnace Making A Banging Noise?
Furnaces are complex machines that are designed to deal with high temperatures and extreme environments. It doesn’t take much for something to go wrong with your furnace, and the noises that this machine can make when you are experiencing issues can be very worrying.

Hearing banging from your furnace isn’t unusual, but this doesn’t mean that you can comfortably ignore it. Instead, you need to make sure that you are looking after your furnace when it has an issue like this. But what exactly causes your furnace to make a banging noise?

Delayed Ignition

Furnaces burn gas to produce heat, and this gas has to be lit for the machine to start working. This is done using a valve that releases a small amount of gas to be lit. If this valve opens before the ignition starts, enough gas can build up to cause a very small explosion and banging noise. This can cause damage to your furnace, with the potential to render it inoperable until you get help with it.

This type of banging will usually only occur when the furnace is turned on and can be solved with some minor work from the experts on furnace repair in Denver, TNT Plumbing Heating and Cooling.

Expanding & Contracting Ductwork

Materials can exhibit a wide range of responses when exposed to extreme heat. Paper and wood will burn quite quickly, while plastic will melt before it burns. Metal is able to withstand far higher temperatures than these materials, but it will expand and contract when exposed to changes in temperature. This can cause metal ductwork to make banging noises as it changes shape as your furnace heats. When extreme, this can cause damage to your ducts as they crack and warp.

Unlike delayed ignition, this type of banging will occur when the furnace is turned off. Dirty and clogged air filters block airflow, causing pockets of hot air to expand the ducting beyond its usual size. Once shut off, they cool down very quickly. TNT Plumbing Heating and Cooling can also help with this type of furnace maintenance.
