This is the time of year 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 issues that need to be inspected. A serious problem you may run into is your furnace making weird noises – take a look at these furnace noises you should never neglect.
If you hear a loud scraping racket that sounds like metal on metal, there is probably something wrong with the blower wheel. If you hear something like this, power off your furnace immediately and call Strand Brothers Service Experts to inspect the system. There are a few things that could be faulty with the blower wheel. First, it may 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 may be that the motor mount itself broke, causing the whole blower assembly to vibrate uncontrollably. One of our service professionals would be happy to come over and take a look, and get you back to the silent and cozy home you have come to adore.
Loud Bang When Furnace Starts
If there is a loud boom when your furnace kicks on, there are a few things that could be happening. Two general things are a dirty furnace burner or ignitor. Stretching and contracting air ducts can also produce loud noises after the heating blower turns on. A dirty furnace burner or ignitor could delay the burners from igniting, resulting in gas to build up. When the gas does finally ignite, it will create the loud boom you hear. This could end up being a safety issue, especially if one of these small explosions caused the heat exchanger to crack. Not only could that result in a carbon monoxide leak, but you would also have to replace the heat exchanger, which could be very expensive.
The other issue, extending and contracting air ducts, is a usual noise complaint for homeowners with metal ducts. If your equipment is making the loud boom and it is a result of your air ducts, it could be an indication of undersized ducts, closed vents, or a clogged air filter. Strand Brothers Service Experts is happy to visit your home to diagnose your problem and get your home back in shape for the winter. Ultimately, this will also provide improved comfort as well.
If you hear a whining noise, it could be the shaft bearings are in need of oil, there is an issue with the blower belt, or the blower motor is malfunctioning. A routine heating tune-up will help discover these issues before they become big problems so make sure you contact us at 512-592-3072 and we’ll make sure your heating equipment is ready to keep you safe and warm all winter long.
