Loud noises coming from your furnace can be alarming, but it doesn’t mean there is a huge problem. When you hear a banging noise, the problem can be simple to fix. Whether you need to replace a dirty filter or clean your ductwork, loud noises are due to several things. We don’t recommend attempting a DIY repair to fix the problem. It’s time to call in a professional for furnace service. Here are some things you can do to try and fix the problem yourself.
Change the Filter
A filter inside your furnace can cause a banging sound when the furnace shuts off. A clogged filter can cause this problem, and a filter that’s not correctly in place. Extra air gets into the furnace and ductwork, causing a banging sound when it shuts off.
The Ductwork Needs Cleaning
Similar to the air filter, if the ductwork is partially blocked, air won’t be able to flow freely. Your ductwork should be replaced or cleaned to help get rid of loud noises.
The Dampers Can be Adjusted
Your ductwork is sensitive to temperature changes and expands and contracts when the system turns on and off. If you hear loud noises, try opening up a damper to see if that improves the airflow in your ductwork and removes some of the noise.
Clean the Fan
A dirty fan can cause your furnace to make noises when it shuts off and on. The fan is inside the ductwork and should be inspected and cleaned if you hear sounds from your furnace. If your furnace makes loud noises, it may be time to call the professionals. Contact the experts at Smoak’s Comfort Control online today or call them at 843-556-9550.
