Minneapolis home covered in snow with large icicles hanging from gutters.When the cold Minneapolis snow begins to fall, there is nothing better than cuddling up under a blanket and sipping some hot cocoa. The cold weather is the perfect time to turn up the heat in your house and get comfy. However, if you begin to hear some strange noises coming from your furnace, it could mean that a repair is necessary. With a damaged furnace, you could be facing a cold winter. Instead of letting your system freeze you out, pay attention to the weird noises. What do those clinks, clunks, and whistling noises mean? They could mean nothing, or they could be a reason to call someone who specializes in home furnace installation in Minneapolis. Either way, here are a few ways to decode what those furnace noises mean.

    • Loud booms or thuds. While these thumping noises may be alarming, they could be relatively harmless. Often times, it could be the ducts contracting and expanding with the heat and the cold. However, it also might be a problem with your furnace’s burners. If they appear to be dirty, it’s best to remove them and clean them with hot and soapy water. Once they are completely dry, reinstall them. If you still notice that the thudding is occurring, you could be dealing with a defective gas valve. If this is the case, it’s always best to call a technician to examine your system.
    • This unnerving noise is often a sign of trouble. Whether loud or soft, it’s important to pay attention. While your system might make a slight humming noise when it starts up, it shouldn’t ever begin to screech or squeal. If it does, it could be an indicator that there is a problem with the motor. If the motor isn’t the culprit, it could be a bearing that is loose. No matter what it is, it’s best to call a professional to check it out.
    • Your furnace will have a natural noise it makes when it is starting up and while it is running. However, if you begin to notice a metallic chirping noise, you may want to do some investigating. Try wiggling the fan wheel to see if it may be out of alignment. If you notice that this doesn’t quiet the sound, take a look at the mounting pump. Sometimes, it can become warped and rub against the blower wheel. If that doesn’t seem to be the problem, check the motor mounts and bearings. If you notice a problem with any of these parts, seek the help of a professional as soon as possible. This will help to prevent future costly repairs.
