Now is when families start turning on their furnaces to settle in for a long winter. Unfortunately, when some furnaces start up, especially if it hasn’t received a yearly heating tune-up, there are some troubles that need to be examined. A big problem you may run into is your furnace making unusual noises – read about these furnace noises you should never ignore.
If you hear a loud scraping sound that sounds like metal on metal, there is likely something faulty with the blower wheel. If you hear a sound like this, turn off your furnace immediately and call Service Experts Heating & Air Conditioning to inspect the furnace. There are a few things that could be wrong with the blower wheel. First, it might just be loose and if the part is not too impaired, can be tightened. Second, it could be that the blower wheel is broken and in need of replacement. Or third, it could be that the motor mount is what broke, causing the whole blower assembly to vibrate uncontrollably. One of our service experts would be happy to come out and take a look, and get you back to the silent and comfortable home you have come to adore.
Loud Bang When Furnace Starts
If there is a loud pop when your furnace kicks on, there are a handful of things that could be going on. Two typical issues are a dirty furnace burner or ignitor. Extending and contracting air ducts can also produce loud bangs after the heating blower turns on. A filthy furnace burner or ignitor could prevent the burners from igniting, resulting in gas to build up. When the gas finally ignites, it will create the loud boom you hear. This could cause a safety issue, especially if one of these small explosions caused the heat exchanger to crack. Not only could that cause a carbon monoxide leak, but you’d end up having to replace the heat exchanger, which may be very pricey.
The other issue, expanding and contracting air ducts, is a usual noise complaint for homeowners with metal ducts. If your system is making the loud boom and it is produced by your air ducts, it could be an indication of undersized ducts, closed vents, or a clogged air filter. Service Experts Heating & Air Conditioning is happy to set up an appointment to diagnose your trouble and get your home back to order. Ultimately, this will also provide improved comfort as well.
If you hear a high-pitched noise, it could be the blower belt, shaft bearings in need of oil, or even a malfunctioning blower motor. A routine system tune-up will help catch these issues before they become major problems so make sure you call us at 330-305-2799 and we’ll make sure your heating equipment is ready to keep you safe and cozy all winter long.
