It’s that time of year when homeowners start turning on their heating systems to settle in for a cold winter. Unfortunately, when some heating systems start up, especially if it hasn’t undergone a yearly heating tune-up, there are some problems that need to be inspected. A serious problem you may run into is your furnace making unusual noises – take a look at these furnace noises you should never neglect.
If you hear a loud raking noise that sounds like metal on metal, there is possibly something defective with the blower wheel. If you hear a noise like this, turn off your furnace ASAP and call Comfortech Service Experts to inspect the equipment. There are a couple things that could be amiss with the blower wheel. First, it could just be loose and if the piece is not too damaged, can be tightened. Second, it could be that the blower wheel is broken and will require replacement. Or third, it could be that the motor mount itself broke, causing the entire blower assembly to vibrate uncontrollably. One of our service technicians would be happy to come over and take a look, and get you back to the quiet and cozy home you have come to expect.
Loud Bang When Furnace Starts
If there is a loud pop when your furnace kicks on, there are a couple things that could be happening. Two typical things are a dirty furnace burner or ignitor. Expanding and contracting air ducts can also create loud noises after the furnace blower comes on. A dirty furnace burner or ignitor could delay 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 would also have to replace the heat exchanger, which may be very expensive.
The other issue, extending and contracting air ducts, is a common noise complaint for homeowners with metal ducts. If your equipment is making the loud boom and it is caused by your air ducts, it could be an indication of undersized ducts, blocked vents, or a clogged air filter. Comfortech Service Experts is happy to visit your home to diagnose your issue and get your home back in working order. Also, this will also result in improved comfort as well.
If you hear a whining disturbance, it could be the blower motor is malfunctioning, the shaft bearings are in need of oil, or an issue with the blower belt. An annual heating tune-up will help catch these issues before they become major problems so make sure you call us at 601-852-3105 and we’ll make sure your heating equipment is ready to keep you safe and comfortable all winter long.
