It’s that time of year when families start turning on their heating systems to settle in for a cold winter. Unfortunately, when some heaters start up, especially if it hasn’t received a yearly heating tune-up, there are some problems that need to be inspected. A serious problem you may encounter is your furnace making weird noises – take a look at these furnace noises you should never neglect.
If you hear a loud raking racket that sounds like metal on metal, there is likely 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 couple things that could be faulty with the blower wheel. First, it may just be loose and if the component is not too damaged, can be tightened. Second, it could be that the blower wheel is broken and needs to be replaced. Or third, it may be that the motor mount itself broke, causing the whole blower assembly to shake uncontrollably. One of our service professionals would be happy to come over and take a look, and get you back to the quiet 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 couple things that could be happening. Two general things are a dirty furnace burner or ignitor. Expanding and contracting air ducts can also produce loud noises 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 does finally ignite, 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 would also have to replace the heat exchanger, which could be very pricey.
The other trouble, expanding 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 come out to diagnose your issue and get your home back in shape for the winter. Ultimately, this will also provide improved comfort as well.
If you hear a squealing 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 furnace tune-up will help discover these issues before they become major 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 comfortable all winter long.
