With cold weather already in full force, now isn’t the time to close your ears to the noise going on around you and hope that your furnace just shuts up. Everyone grows accustomed to all of the sounds that go on every day throughout their home. Many tend to tune them out and ignore them. If you end up hearing a new sound coming from your furnace, it’s an excellent idea to let an HVAC technician come out and investigate what the noise might be. You don’t want to wait until after the unit breaks down, especially now that the weather is so frigid.
The Sounds Relating to a Noisy Furnace
Ignoring a furnace that is noisy could end up costing you a large sum of money in repairs or even cause you to replace the unit. In certain instances, the repairs needed might be dangerous to your health and your home. It is imperative that you call in a professional if you hear any unusual noises coming from the furnace. Certain sounds indicate that the furnace is in desperate need of a thorough cleaning. Dirty furnaces could end up catching on fire and destroying the home.
You can expect a certain amount of rattling or popping in your ductwork. Ducts are composed of metal, as it cools and heats, it will contract and expand causing a certain degree of popping. Rattling is a lot more serious and could be an indication that a duct has gotten loose. A technician will be able to localize the problem and get it fixed for you. If the noise is loud or persistent, insulation can be used to muffle the noise.
If you hear clicking before the gas ignites on the inside of your furnace, it might mean that you have a vital sensor that is in dire need of a cleaning. If the problem persists after a technician has cleaned it, you may need to have it replaced. This isn’t something that you should try to repair on your own.
Could It Be Something Larger?
If you hear a loud booming noise after the furnace ignites, the burners probably have a great deal of debris built up on them. The boom sound is the gas pushing and making its way through your pipes. This potential problem can end up leading to costly damage if you don’t address it quickly. Cleaning the burners is something best left to a professional HVAC company.
Furnaces that become suddenly noisy is something that you need to have inspected quickly. Beyond the inconvenience of having your furnace go out in the middle of winter, or worse yet having it catch on fire, it is also a potential hazard to your family’s health.
