Heating FAQ: Why is My Gas Furnace Making That Noise?

Have you recently noticed a loud banging or explosion noise when you turn on the gas furnace in your Coon Rapids home? This can be caused by a few different things, but it’s important that you call a heating technician at Air Mechanical to look at your furnace any time you hear strange noises. We’ll send someone to your home as soon as we can to investigate the issue. Gas furnaces have special concerns due to the combustible fuel source. Improper ventilation, issues with the pilot light, and burner problems can all be hazardous situations. One problem that is not as common but can be easy to detect is a delay in the ignition of the burners. A delay in the ignition of may be an indicator that not enough gas is getting to the burners. One sign that you have a delay issue is if when you turn on the furnace you hear a loud banging sound. You may also hear what sounds like a small explosion when you turn the furnace on. If you hear these sounds or any other unusual sound, it is an indicator that gases within the furnace are not being transferred to the right compartments. This means that excess gas can build inside the chamber, creating the loud banging noise when the furnace is fired up. In addition to being a sign of problems with your furnace, a delayed igniter is a safety issue because it can lead to a dangerous situation for anyone near the furnace or trying to light the pilot light. The accumulation of unburned gasses in the chamber can result in instantaneous or extremely hot fire. For these reasons, if you believe your furnace has an ignition delay, it is important to call a technician as soon as possible. A technician should be able to tell why the gas doesn’t ignite when it should and will remedy the problem accordingly. Contact Air Mechanical for all your Coon Rapids heating repair needs!
