Heating season is here, which means that heating problems are going to start cropping up as more people start to rely on their heating systems for warmth. If you are one of the millions of people who use furnaces, you are going to want to listen for strange noises once you turn your heating system on. These noises can indicate a wide variety of problems with the furnace. Read on to find out more about furnace noises, and what they can mean for your system.
A deep booming noise is quite common in many homes with furnaces. Some homeowners have reported that it almost sounds like a cannon firing. Fortunately, this isn’t as dangerous as cannonballs. Booming noises are often caused by delayed burner assembly ignition. Carbon molecules can build up on the burner assembly, and over time the buildup can cause some jets to fire later than others. When the jet finally does fire, it burns through all the excess gas at once. This is what creates that booming sound.
If you hear your furnace turning itself on and off every few seconds, it’s doing what is called short cycling. Short cycling is the result of a malfunction in the furnace, in which the internal temperature rises to dangerous levels. The furnace shuts itself off as a safety measure, but when it turns back on it overheats again and the cycle continues. This needs to be repaired as soon as possible, since short cycling puts the furnace under far more stress than it is designed to handle. Prolonged short cycling will drastically shorten the service life of the furnace, and also increases the likelihood of a breakdown.
