Are you starting to hear noises in your furnace? Some sounds might be more alarming than others, and you could have a big issue on your hands. However, it could also be nothing! But what if it is serious and you are forced to be stranded in your house or snowed in if it’s winter? But then again… it could be nothing. It’s hard to determine whether or not to call an expert if you aren’t sure if you have an issue on your hands or not. Therefore, if you are hearing some scary noises, here are some things that might be causing them! Banging Noises Louder bangs and booms aren’t normal. If you hear something like a gunshot when you turn your furnace on, you should be worried because it could be a serious problem. You may need to clean your burners or have some duct issues. It could also be a gas buildup. There’s a chance that it’s a quick, easy fix. However, it could also be a problem that could lead to a hazardous carbon monoxide leak. This could also mean that you need to install a whole new system. Either way, you should call your HVAC provider right away. Scraping Sounds If you hear something that sounds like scraping metal, rattles, or clanks, your fan might be loose or broken. This sound may occur when the furnace is on. You will want to call in a technician in case it is a case where the heat exchanger is cracked because this could be a more serious issue that should be fixed right away. Metal scratching metal can never be good. Buzzing Noises Buzzing will usually indicate that there is something loose inside your HVAC system, mainly in the transformer. This may not be as dangerous as a gas leak, but it will definitely be an annoying noise to listen to. Your furnace will need to work harder to keep the inside of your house comfortable with this sort of issue, which is why you should get this fixed right away. It could just be the tightening of a loose bolt, but even so, make sure to have them inspect your system while they are at it. It’s always good to have someone check an issue if you are hearing strange noises in the case that it could be potentially dangerous. You could also save yourself money. If your furnace is working harder and longer without making your living space comfortable, you will have to pay a lot more in energy costs. Squeals Screeching noises most definitely should not be ignored. It could mean damage or a loose component in your blower belt, a malfunction in your blower motor, or maybe just a need for some lubrication. Whatever it is, fixes like these will not be as time-consuming or costly, but it is important to take action if something out of the ordinary is happening. Pops Clicks and pops can mean a malfunction in your wiring or flame sensor. They could also mean a gas leak or that your burners need to be cleaned. Aside from those things, pops could also be an indication of air duct damage or that cleaning is needed. The situation can potentially be dangerous, so it’s best to get it checked out just in case. With any of these noises and sounds, it’s always best that you get your HVAC system checked, even if it doesn’t seem serious. Who knows? You may be saving yourself a ton of money in the long run. It’s always better to be safe than sorry. Are you looking for an HVAC repair service? Contact us today! We’re based in Plano, TX. Get in touch to see how we can help.
