Now is when homeowners start turning on their heating systems to settle in for a cold 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 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 scratching noise that sounds like metal on metal, there is likely something defective with the blower wheel. If you hear a sound like this, turn off your furnace immediately and call Mountainwest Service Experts to inspect the system. There are a few things that could be amiss with the blower wheel. First, it might just be loose and if the part is not too damaged, can be tightened. Second, it could be that the blower wheel is broken and will require replacement. Or third, it may be that the motor mount is what broke, causing the complete blower assembly to rattle uncontrollably. One of our service technicians would be happy to come over and take a look, and get you back to the noiseless and warm home you have come to adore.
Loud Bang When Furnace Starts
If there is a loud boom when your furnace comes on, there are a handful of things that could be happening. Two common issues are a dirty furnace burner or ignitor. Stretching and contracting air ducts can also create loud booms after the heating system blower starts up. A soiled furnace burner or ignitor could holdup the burners from igniting, resulting in gas to build up. When the gas does finally ignite, it will create the loud pop you hear. This could cause a safety issue, especially if one of the small explosions caused the heat exchanger to break. Not only could that result in a carbon monoxide leak, but you would also have to replace the heat exchanger, which can be very pricey.
The other issue, extending and contracting air ducts, is a typical noise complaint for homeowners with metal ducts. If your furnace is making the loud bang and it is a result of your air ducts, it could be a symptom of undersized ducts, closed vents, or a clogged air filter. Mountainwest Service Experts is happy to set up an appointment to diagnose your problem and get your home back to order. Ultimately, this will also provide improved comfort as well.
If you hear a whining disturbance, 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. An annual system tune-up will help discover these issues before they become big problems so make sure you give us a call at 385-399-0280 and we’ll make sure your furnace is ready to keep you safe and comfortable all winter long.
