This is the time of year people 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 assessed. A serious problem you may encounter 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 immediately and call Comfortech Service Experts to inspect the equipment. There are a few things that could be wrong with the blower wheel. First, it could just be loose and if the piece is not too damaged, can be tightened. Second, it may be that the blower wheel is broken and will require replacement. Or third, it may 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 warm home you have come to love.
Loud Bang When Furnace Starts
If there is a loud pop when your furnace kicks on, there are a few things that could be happening. Two typical things are a dirty furnace burner or ignitor. Expanding and contracting air ducts can also cause 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 result in 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 typical noise complaint for people with metal ducts. If your system is making the loud boom and it is caused by your air ducts, it could be an indication of undersized ducts, closed vents, or a clogged air filter. Comfortech Service Experts is happy to come out to diagnose your problem and get your home back to order. Also, this will also provide 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 furnace tune-up will help find these issues before they become big 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 warm all winter long.
